LED is better than LCD picture quality
This rumor logic is clear: Since the LED TV is the latest out, then the quality is certainly better than in the past with CCFL backlight ( commonly known as LCD) LCD TV is good. What this really true ?
As mentioned earlier , LED TV's biggest advantage is long life , high brightness, low power consumption, small size. As to the quality better than that of LCD, but also depends on the spectral characteristics of the LED , high- performance focusing on only those LED TVs , by using particles of a high-performance LED , combined panel and picture quality processing techniques to achieve high quality. In addition , in the past , when the LED TV does not appear , there are many high-end LCD TV by using a high performance CCFL backlight and panel to achieve a high quality , which is the same reason.
5 = buy buy LCD TV panels
LCD panel LCD TV sets accounted for more than 70 % of the cost , this is not to deny the fact . But does that mean that buying a TV panel is to buy it ? The answer is of course no.
The following reasons:
1 , the LCD panel only occupy a larger share of the costs of the machine . For "good" TV and " bad" TV is the same.
2 , bucket theory tells us that the key factor in determining good or bad thing is how short the shortest piece of board , rather than how long the longest piece of board . So if only the LCD panel is good,20x4 lcd
display the other bad parts , but also can not make a good TV.
3 , even the best LCD panel plant , out of the products have quality differences. Can not say that so and so long as it is produced in a liquid crystal panel is good, so and so is the production of LCD panels bad .
6 , hard screen than the soft screen strong , impact
This statement is more popular in the last year , many consumers once considered hard-screen LCD TV in front of the screen adds an extra layer of protection , so the more solid , impact resistance. At that time a lot of sales in stores selling television sets in order to prove himself with a "hard screen" , will hand to knock , push the TV screen , in order to prove their strong sales of the TV screen , and durable.
In fact, the difference between hard and soft-screen in the direction of the liquid crystal molecules are arranged just different decision . Hard screen and no additional protective layer on the surface, so it does not seem to be more solid than the soft screen , impact resistance.
In fact , the biggest difference between hard and soft-screen or display different characteristics , focusing on hard screen color reproduction of authenticity , but generally not as soft contrast screen ; soft screen contrast generally good , but the color is more obvious tendency . In fact, this is the difference in style ,Character LCD
Modules and physical structure , is strong, durable , and no significant relationship .
A liquid crystal panel section of the module (LCM): panel process can be divided into three stages, first semiconductor processes preceding (array), that is, the transistor is a thin film layer on the glass substrate made, compared with the middle of the liquid crystal filling assembly process (cell), that is, the color filter layer of glass and glass film transistors, together, poured into a liquid crystal intermediate.
