Screen. First of all, the screen of LCD TV can account for 60-70% of the total cost, which is directly related to the cost of LCD TV. At present, the seventh generation LCD panel production line of upstream suppliers has been established, which has achieved a leap in both cost and performance. Consumers can give priority to TV products with new panels when purchasing. Take the s-lcd factory, a joint venture of Sony and Samsung, which was the first to establish the seventh generation LCD panel production line, as an example. Its production line has been able to produce 60000 pieces of base plates per month, and each base plate can cut 8 pieces of 40 inch or 6 pieces of 42 inch LCD screens, that is to say, it can support the monthly production of 480000 40 inch LCD TVs, greatly reducing the screen cost. The resolution of the new screen is as high as 1366 × 768, the viewing angle has reached 178 degrees, and the response speed has reached the world's fastest 8 milliseconds, almost comparable to CRT TV. In addition, the physical resolution of the screen is an important index to measure whether a TV reaches the high-definition level. The physical resolution of the high-definition TV should reach at least 1280 × 720, otherwise HD signal can only be degraded. In August 2005, CCTV asked dozens of TV manufacturers at home and abroad to send their flat-panel TV products to the national authoritative testing agency digital TV product quality testing laboratory for HD testing. In the test results officially released in September, LCD TV basically passed, but most isoionic TV failed, So now when you buy LCD TV, you don't have to worry about the physical resolution.. Backlight. Unlike the plasma screen, the LCD screen itself does not emit light, and the light we see comes entirely from the screen..
