Power Consumption in CRT TV

dipti — Mon, 28 Nov 2011 11:58:09 +0000

Do you have any idea how much power CRT TV consumes when it is on? The answer can be a cause of worry for you.

Everybody needs modern appliances for their homes and such appliances are more power hungry as compared to older ones. Excess of circuit boards, lights and buttons suck electricity at fast rate. If you compare an old TV and new generations highly advance TV, you will find huge difference between electricity costs of both. Size and technology also matter a lot. Let’s see how size and technology influence the electricity consumption in a TV. In order to produce picture on TV screen, four kinds of technologies are required.

Normal CRT (Cathode Ray Tube) TV consumes a lot of power to generate black and white screen. Backlight of TV runs at maximum power. However, if you check out same old CRT TVs, you would get to know that power consumption by them was lesser, hence they produced dimmer images and this is the reason why they were replaced by new CRT TVs. 45 watts of power used by 20 inch CRT TV can be used to charge laptop, and 55 inch plasma TV can consume up to 507 watts of power, that is close enough to a large size refrigerator.

Most of the TV manufacturing companies have considered this issue and introduced power-saving mode in their new televisions like Maxent’s MX-50X3. Never forget that for any electrical appliance size matters a lot, that is why experts have divided power use by the area of the screen so that they can calculate watts per square inch and can calculate power consumed by large and small size screens. If you check out TV power consumption chart you will see that results are quite interesting, CRT consumes 0.25 to 0.40 watt per square inch, LCD consumes 0.16 to 0.41 watt per square inch and Plasma screen consumes 0.30 to 0.40 watt per square inch.

If power is the only concerning factor for your television, then you can switch to rear-projection technology but the only problem is that the image you will see is not as bright as other television gives. Another power consuming factor related to TV is that it consumes power even if it is not turned on. So the latest TV manufacturers have incorporated standby power mode. Some TV sets use nearly 20 watts of standby power while other uses 20 watts of power, but the standby power gets added to the overall electricity consumption of the television.

Most of us use TV as a source for other devices like gaming console, DVD player, external speakers and handy cam but don’t forget that they all need power to function. The shocking result is that Xbox 360 uses 160 watts which is more than any big screen HDTV tested by the experts. If you want to keep a track of total electricity consumed by your television, you can do so by recording actual current flow into your television so that if you want to reduce power consumption, you can do so by using such power measuring instruments.

Finally this serious issue of excess of power consumption by TV has been considered by major TV manufacturing companies and they are working hard to make their product more efficient by reducing its power consumption. So new age LCD TVs are better choice when compared to CRT TVs from power consumption point of view.

Computer Monitors CRT

HighDisplay — Sat, 16 Jan 2010 18:34:17 +0000

Computers are essential in the world of technology in which we live nowadays. Computer monitors are very important hardware components for users. In present, there are two basic types of computer displays: the cathode ray tube type and the liquid crystal display type. CRTs are considered the old fashioned type of monitors, while LCDs are the modern ones which are used by almost every user these days. Even if cathode ray tube type of monitors have been widely used in the past and nowadays most of the users prefer to have liquid crystal display types of monitors there are still available for users some interesting models of CRTs available on the market for users to analyze and see whether they might enjoy working with them or not. This is because many of the old models of CRT computer monitors have been changed and improved so that they might have better features included and become a possible choice for users to work with. When discussing about which of the two types of computer monitors is better it should be mentioned the fact that both of the two types of computer monitors present advantages and disadvantages. In this way, we cannot say that all liquid crystal display monitors or all cathode ray tube type of monitors is good or bad. They all present good and bad aspects and this is why it is important for users to analyze the offers made available to them by the companies manufacturing these products and decide for themselves whether they might enjoy working with one type or another of computer monitors.

In order to be able to decide whether CRT computer monitors might be considered to be good ones or not it is important to analyze both their advantages and their disadvantages. These are also general types of data which do not characterize all the models of CRT computer monitors but which are possible to be encountered in some of them. In this respect, it is important to be mentioned among the advantages that have been considered to be presented by CRT computer monitors the high contrast ratio which is considered to be better than the one presented by many of the liquid crystal display type of monitors, the great additive color which presents a low black level that has been widely appreciated by many users. Also advantageous related to this type of computer monitors has been considered to be the fact that it is considered to be able to display images and texts in almost any resolution and refresh type of rate. This is a very important feature but it is also true that this is not a characteristic of all the cathode ray tube types of monitors. There are certain models which have been improved and for which this can be applied but there are also others for which this does not apply.

Another important advantage presented by CRT computer monitors has also been consider to be the fact that they are said to present almost no saturation or brightness type of distortion, which is very important in determining a good imaging quality. Again, it is important to be mentioned the fact that this is also a characteristic that characterizes some of the CRTs but not all of them. The good viewing angle presented by most of the cathode ray tube types of displays has been included among the advantages presented for this type of monitors.

There are also certain drawbacks which should be considered related to CRT computer monitors. The most obvious one is represented by their size and weight which determines many users to prefer using liquid crystal display types of monitors which present a nicer design and which are said to weight less than the CRTs. It has also been considered that old models of CRTS presented a geometric distortion which interfered with the quality of the images being displayed. These older cathode ray tube types of monitors have also been considered to be exposed to the risk of burn-in. The power consumption has also been evaluated to be greater than in many of the liquid crystal display type of monitors. Some of the CRT computer monitors, especially the old ones have been discovered to present the risk of wet failure, which can lead to an immediate deterioration. The voltages have been considered to be very high which can also lead to severe damages being caused to this type of computer components.

Another drawback having been considered by users of old CRT computer monitors is the fact that they present a lower brightness within the images being displayed. It has also been considered being very hard to actually be able for companies to manufacture good models of CRTs at high definition resolutions because they are generally seen as antiquities by most of the users. It has also been considered very difficult sometimes to actually find necessary monitor parts to be used when certain problems are being encountered by users working with these types of computer displays. Taking in account the fact that almost everyone uses liquid crystal display type of monitors there are easily found all sorts of spare monitor parts for this type of monitors which makes the other type to be very rarely and hardly found.

There are many important aspects which can be analyzed when discussing about CRT computer monitors. Both the advantages and disadvantages that have been presented should be analyzed so as for users to understand what this type of monitors actually means and what their functions are. It is also important for users to be aware of the fact that these characteristics do not apply to all the CRT computer monitors but they have been encountered in some models, especially in the old ones.

The modern models of cathode ray tube type of monitors have been very much improved and in this way they might be considered a possible choice for many users who might want to try and see whether they are actually better or not. It is possible for users nowadays to analyze all sorts of computer monitors, both CRT computer monitors and liquid crystal display type and in this way we can all decide whether one type of computer display or another might be better to be considered a possible choice for users to have and use.

Computer Monitor CRT

There are two main types of computer monitors present on the market nowadays: the Liquid Crystal type of monitors and the Cathode Ray Tube type. There are numerous and various models that have been presented among the offers of the market. They are all different according to their size, their resolution, their brightness and many other features that characterize them. CRT computer monitors are considered to be the old model, as nowadays many users use LCDs, which are considered innovative and more performant. There are still users who have CRTs and are still satisfied with the way in which it functions. In the end, it all depends on what each user wants and chooses when he or she buys a computer monitor.

<-300×250 Medium Rectangle – center->

The Cathode Ray Tube is the picture type of tube within a monitor. The users, when buying a computer monitor are interested in the performance of the monitor. This is because we all want to have a good, performant computer monitor so as to be able to work properly with our PC. The performance of a computer monitor is usually established by taking in account important features related to the monitor: the luminance, the viewing angle, the aspect ratio, the resolution of the display, the dot pitch, the refresh rate, its response time, the contrast ratio and the power consumption. These features are taken in account when analyzing both CRT computer monitors and LCDs.

There are users who still consider CRT computer monitors as being very good and do not agree with the fact that LCDs are necessarily much better than the old type. Others in exchange do not even want to hear anymore about the CRT type of computer monitors as they are using LCDs and consider them much improved than the other ones. Among the features which make the Cathode Ray Tube type of computer monitors to be used by some of the users are considered the high contrast ratio, the high seed response, the colors, the low black level, the brightness, the excellent viewing angle and the display technology. Users who still have and work with this type of computer monitors consider them to be very good because of these good features that characterize them.

There are also persons who do not agree with those who still consider CRT computer monitors as a good component for their computers. Among the bad features about the Cathode Ray Tube type of monitors are considered to be the large size, the weight, the geometric distortion, the big warm-up time, the big power consumption, the possible failures which usually happen with them, the high interior voltages, the brightness which cannot reach the maximum value reached by the LCDs and the lower contrast ratio. The opinions are numerous and various related to the performance of CRT computer monitors. In the end, every user chooses what kind of computer monitor to use and why.

One example of CRT computer monitor is Samsung Sync Master 790DF-Black. Its size is of 17 inches, with a viewable image size of about 16 inches. It presents three different brightness settings and a variety of features and applications included. Its resolution is of 1,280 x 1,024 and the dot pitch is a.20 mm. The images displayed on the screen are very clear and accurate. It supports an RGB type of input signals. The power consumption has been evaluated to be of 80 watts during a normal type of operation. The horizontal frequencies are 30 to 70 kHz and the vertical one is 50 to 160 Hz. The maximum bandwidth is of 110 MHz this computer monitor weights 31.5 pounds. The offer presented by the Samsung Company includes the monitor, the monitor base, and a 15-pin D-sub type of cable, a power cord, a warranty type of card, a useful guide and a CD-ROM with the user’s guide.

Another example of CRT computer monitors is Samsung Sync Master 750S White. Its size is of 17 inches. The resolution is of 1280 x 1024 and the horizontal frequency is of 30-70KH. It presents an analog type of interface. Among the many features included within the offer presented by Samsung Company is fully supplied software, a plug and a plug type of compatibility, an integrated power supply and multimedia speakers.

Samsung Sync Master 753DF-T/T CRT computer monitor is another example of computer monitors presented by the Samsung Company. Its size is of 17 inches. It is characterized by a great precision. The horizontal dot pitch is of 0.20 mm and the resolution is of 1280 x 1024. The horizontal scanning frequency is of 30-70 kHz and the vertical one is 50-160 Hz. It also has included an anti-glare surface type of treatment.

One of the main problems considered by the users related to CRT computer monitors is their large size. The size of the Cathode Ray Tube type of monitors is usually measured diagonally by taking in account the lower corner and its opposite. On the other hand, very important about this type of computer monitors is the fact that there are various resolutions available for this type of monitors.

Nowadays, the Cathode Ray tube type of computer monitors are considered to be the old fashioned type because almost everyone has and uses nowadays a Liquid Crystal Display type of monitor. This does not mean that they are not used at all. There are still some users who use them. CRT computer monitors represent the older type of computer display, but it still presents some features that can even be considered better in comparison with the LCDs. It also presents certain disadvantages, such as the large sizes in which it can be found. It all depends on what each user decides to be most important for him when buying a computer monitor: the size, the resolution, the contrast ratio, the aspect ratio, the luminance, the viewing angle or another important feature. What is important is that we have many offers from which to choose so that each of us might buy the best computer monitor that can help us work easier and properly with our computers.

CRT Computer Monitor

HighDisplay — Tue, 10 Nov 2009 14:21:37 +0000

The CRT monitor was one of the most common computer monitors up until a few years ago. Today it is loosing more and more ground to new and technologically improved monitors like the LCD(Liquid Crystal Display) monitor which has climbed to the top of the computer monitor purchases. Despite this recent decline of the CRT monitor and the uprise of LCD monitors on the market, experts say that CRT monitors are not dead, but rather they will live as a niche product.

<-300×250 Medium Rectangle – center->

CRT monitors are based of the cathode ray tube technology invented by German physicist Karl Ferdinand Braun in 1897. Cathode ray tubes consist of a glass vacuum tube inside which an electron gun emits electrons that are guided by an electrical field towards the screen. The screen is covered in small phosphorescent elements. The electron beams move back and forth across the back of the screen illuminating the phosphorescent elements. The gun that emits electrons is made up of a cathode and one or more anodes. The cathode, which is a negatively charged metallic electrode, emits electrons that are attracted by the anodes, which are positively charged electrodes. The electrical field which guides electrons is made by the anodes who act as accelerators for the electrons and concentrate them into beams. These beams light the phosphorescent elements on the screen in lines. This is accomplished by using two deflectors (electrified X and Y plates). The magnetic field generated helps the electrodes to move left to right (horizontally) and top to bottom (vertically).

The lit-up dots that appear as a result of the movement of the electrons are called pixels. The number of pixels that a monitor displays is called definition (often confused with resolution) and starts as low as 640×480. Resolution is actually the number of pixels per surface unit which is abbreviated as dpi (Dots per inch). The refresh rate represents how often the image is refreshed each second and it is expressed in Hertz (Hz). Dot pitch is tied up to the image quality. Lower dot pitch means better image quality.

CRT monitors are sold based on the size of their screens, which is measured diagonally, from corner to corner including the case. The measurement is done in inches, CRT monitor size ranging from 15 to 21 inches (38 – 53 cm). The actual size of the screen which is viewable is in fact about 1 inch smaller because of the monitor casing and because the tube can not project the image to the edges of the tube.

While the CRT monitor has some good qualities like high speed response, higher contrast rate than many many LCDs computer monitors, excellent viewing angle, able to display in almost all definitions and refresh rates and has proven to be a reliable display technology the negative aspects of it have proven to be it’s undoing causing its decline and the rise of of LCD monitors despite the fact that these cost more.

Among the negative aspects of the CRT monitors we have the large size and weight, greater power consumption compared to LCD monitors, the fact that lower refresh rates cause noticeable flicker. It’s also intolerant of damp conditions, prone to burn-in (older models), internal lethal high voltages, lower maximum brightness than LCD monitors and geometric distortion in the case of non-flat CRTs.

For low budget people and home users it is still a viable alternative since it cost a lot less that a LCD computer monitor.

Top Rated Computer Monitors

HighDisplay — Thu, 17 Sep 2009 07:59:03 +0000

You can’t say that they are as good as the flat-panel displays or as sleek but the traditional 19 inches monitors have a large viewable area than the LCD monitors costing hundreds of dollars more in some cases. You may need a much bigger desk to hold one of these devices but if your choice is the most screen space then you should try a 18 inches CRT computer monitor. We shall present you with ten of the best options, top rated computer monitors.
<-300x250 Medium Rectangle - center->
The first one is the Samsung SyncMaster 957mb being highly recommended for its shap text and vivid graphics at a very reasonable price. It even has an adjustable highlight box that will let you brighten the screen areas. Its price was ranked at $319.

The Phillips 109B43 has the best colors and produces the best realistic and lively images, with a intuitive monitor controls with fine tuning and software for image adjustment. It was recommended also for its manual and its prices are between $200 and $250.

An accurate and vivid photographic imagine provides even the Compaq S9500 with his on screen controls which are easily used to get high marks and without no software for the image adjustment.

The ViewSonic G90f will liven up your photos and enrich them with warm and wonderful colors but the text will appear small for some and many times blurry. This one although has got an adjustment software being ranked at $239.

For users that do a lot of on screen writing or reading the best choice would be the Dell M992 monitor, which displays the text clearly, even the smallest font will be seen crystal like and with a color mapping profile. At $249 this one would be a bargain.

The Mitsubishi Diamond Pro 930SB has the same text features but comes with extra ones such as color adjustment software and toggling to a brighter setting with just one button press. You would find on the market at $340.

Better with graphics than text, would be the Hitachi CM721F that comes with many features like good on screen controls for only $266.

The IBM P97 has realistic colors, rich and very good looking photos, images, making this the ideal graphic application monitor. There are some disadvantages to it for instance its pretty expensive, it was priced at $409, and the user controls are not that intuitive.

And last but definitely not least is the Hansol 920D monitor, which is a very well priced monitor, you can find it on the market at $249, and it is considered the best bargain if you are looking for graphics quality. It displays the text very crisp but sadly, the on screen controls are not that great, being difficult to surf on the internet and it does not have a very helpful manual

If you still are undecided in the case is what is the best rated computer monitor, after reading this article you should go into a store or online and ask around more to be sure that when you are going to buy your monitor, it will be the best choice and it will satisfy you technological needs.

What Is A Computer Monitor?

HighDisplay — Wed, 09 Sep 2009 18:46:44 +0000

We all use our computers every day and we know quite a little bit about the gadgets that it has and it needs to perform at its maximum capacity but does not anyone knows how to explain exactly what is a computer monitor and what makes it so important for the computer use. The computer monitor is an output device that is part of the display of your computer.
<-300x250 Medium Rectangle - center->
The monitor is connected to a video adapter or a video card through a cable and it is installed on you computers’ motherboard in an expansion slot. The system changes the signal into images, displays and text like on a TV like screen – the monitor. The video adapter receives a signal from the computer that tells it what kind of image, character and graphic should it display. That signal is converted by the video adapter into a set of instructions that say to the display device, the monitor, how and why to draw on the screen the imagine.

The ‘picture tube’ or the CRT, Cathode Ray Tube is like a large vacuum tube that is shaped like a bottle. It tapers in the back where there is a negative charged cathode or as it is called ‘electron gun’. This electron gun shoots electrons to the back of the positive charged screen which has a coat of phosphorous chemical. This excites the phosphor making it glow as individual dots, as we know pixels (picture elements). The imagine that we see on the computer screen is made up from thousands of these dots, pixels.

The quality of the imagine has to do with the distance between the pixels and if the distance between the pixels is too big the imagine will appear grainy. The main issue is that the closer the pixels are the clearer and sharper would be the imagine. That distance is called dot pitch and the best monitor you should get is with .28 mm dot pitch or less. If we are to look at the computer monitor from an environmental point of view, the most difficult computer peripheral to dispose of is the monitor because of the lead that the monitor contains.

A couple of electromagnets ( yokes ) are around the collar of the tube that bend the beam of electrons which scans all across the monitor from left to right and top to bottom to draw or to create the image line by line.
