LCD Monitor

To the LCD Monitor (including Desktop PC and Laptop PC) and LCD TV this level, inches count has exceeded 700, "there are at least 8.4", 12.1 ", and even the majority in 15", 17 "or more, this level WLED there with PDA / PMP levels were the same degree of light problem, and the ratio is even more serious when the number of small and medium-inch, while the price derived from the heat problem and the problem to be solved.TFT Display Module
First explain heat problem, it is a large-size LCD backlight, due to the low flat space in the clouds a lot of WLED, WLED will not easily dissipate the heat, which is kind of CCFL cold light does not have the problem, and must be light are all taken into account and heat two, but not feasible due to heat unevenly luminosity. In addition, there are industry (eg Sony) overcame WLED backlight thermal problems, and then launch the actual production of LCD TV products, but the first to overcome the industry will also cooling technology patent, so that other operators is difficult to follow up, and let inch WLED backlight for large number of products hinder the progress.
Followed by the price, the current unit cost of WLED technology is still high due to phosphor patents, according to estimates of the number in the same big-inch backlit demand, the cost will be using WLED CCFL five times, and therefore at this stage Sony, Samsung and other industry although the actual volume production launch WLED backlit LCD TV, but all appeals in the high-price, high-quality article. WLED backlight so the price is hard to spread the high number of applications an inch big reason, although the number of small and medium-inch spread applications have the same problem, but not as good as the number of big-inch camel obvious.character oled
