2. WHAT DO YOU KNOW ABOUT SCREEN: Last year was the end of a chapter control screen technology- based cathode ray tube (crt) devices on the market, desktop computers. Where the top Mraguib LCD (lcd) sales this year. This subject will be trying very hard to know you the difference between both plasma screens and the Lcd and Crt and also new technologies in the world of screens. Badr reading this post, you will think that very technique Crt screens in the leg. And of course the reason for this innovation manufacturing companies sought to get a more pure in both the small screens of mobile devices in addition to the screens to compete with the tubes. Of defects in the screens tubes, for example, they increase at an average depth of 8 times more space doubled the horizontal screen. Which makes it impractical when you need to screens.

3. KINDS ABOUT SCREEN: 1:LCD Features WHITH :Famous for the quality of the screens elegant appearance and attractive design But you overlook the flaws of many - Do not fit this screen movie lovers and gamers or rather do not represent the best option and this was because Alchrisital molecules move from one point to another relatively low speed. Which makes movies and games, Video, look stained. The tubes and monitors are the perfect choice for such use due to instantaneous excess phosphorus on the screen with the cathode ray electrons - Requires screen Amartistalip for so is 16 to 25 milliseconds to change from white to black and back to white, while consuming 4 times this time to change from a derivative of gray to the derivative of another of the same color of course this is not important for the images of the other mobile or the fact that the biblical texts become a problem in watching movies - Those screens suffer from another problem, which change the angle seen and of course superior screen tubes because it is transmitted light from the surface of the screen and launched in all directions, while liquid crystal molecules have six Scala. It may therefore seem the image of straight forward but it is not angled in different

5. 2:CRT Features WHITH :1 - Some cathode ray tube screens were sold for less than than 900 Egyptian pounds, while the LCD was sold five times that amount and Batali had such statistics do not reflect the volume of sales but does not prevent the other's sales volume was actually higher _ Of course, taking into account that some companies but not all screens stopped making cathode ray tube (CRT) at the moment 2 - I screen cathode ray tube (CRT) is always the best performer in the past and this performance was a rock, which crashed by Mraguib LCD competition every time. As they represent the best solution for many because it was less expensive and enjoy the sympathy of professionals and lovers of movies, games and of course those days it had changed completely The only thing that was a superior screen cathode ray tube (CRT) technology liquid crystal (LCD) is the cost Alovtsade This has now ended and this down the curtain on the screen cathode ray tube (CRT).

7. THE DIFIIRENT BETWEEN PLASMA AND LCD: 1:The plasma deal with a broadcast image to you via the gas!! As for the LCD, they rely on liquid. 2:Beats the LCD screen if you simply close after the text of meters from the screen kept CLEAR full clarity Would have no effect on the eyes Unlike plasma, if approaching the same distance will not see the image well and tell a danger to the eyes.

8. For the size of the screen: Ever seen plasma screens up to 80 inches or inches and has the largest As for the size of the LCD and more is now is 46-inch Sony-made and available in this size so far only to consumers in Japan, America, for we have in the Middle East and Europe, there are 40-inch Sony 43 inch I think of the Samsung If plasma superior to the LCD size..

9. Weight and design: As to the form vary from one company to another But LCD screens are characterized by Bkhvtha Unlike plasma screens are HUGE Here are superior LCD weight, but weight is not important except in some of the requirements....

10. Consumption: Htina if a certain number of hours for example, say 4 hours a day and to have been testing and Plasma would consume an average of 4 hours a day, claimed the lives with you 20 years LCD, while an average of 4 hours per day consumption claimed the lives you Dubl 40 years!! But what is important in that the plasma after the consumption end and unfit LCD, but require you to only change made in the heart of the device and started a new device Erdjalk Excel here of course the LCD but generally for consumption plasma fairly reasonable..

11. Clarity of the image: The most important thing Plasma-Z i said it Tbutlk image by gas As for the LCD through the liquid They excel more clarity from the plasma.

12. (CONTRAST):What is meant by the highest degree of color white and the highest degree of color estimates provided by Black screen.. All Mazad Halmadl increased the ability of the screen to show details better image "... In terms of contrast plasma was estimated to reach a very high degree of showing black reach reach Makedrt 3000:1 LCD screens have the highest number reached a 1000:1 but of course that the LCD ISNT MEAN bad are estimated as a result gives you more than enough for the degree of color to the black
