LCD lamp and other related arguments detailed

Since the LCD is a cross between between solid and liquid substances, so the LCD itself is not luminous, for technical, cost and design control and other considerations, it is impossible for every Character LCD Module monitor LCD pixel is individually assigned a light, and therefore have internal lamp to illuminate the LCD panel. Is currently using more than two lamps designed that the upper and lower sides of the liquid crystal have a lamp, the liquid crystal is also the most common.
           
Now, with the technology continues to evolve, but also began to appear four and six lamp lamp design. In the four-lamp camp divided into two categories, one category is based on the original two lamps, the left and right of the screen each increased by a lamp, the lamp became four, more typical Mayan V500; while the other two are in the original lamp, based on a parallel increase in the upper and lower lamps, four parallel composition of the lamp, more typically Xunyi "Chun Jingjie" LCD.
           
We look at six lamp, in fact, six lamp design actually uses three lamps, manufacturers will have three tubes bent "U" shape, and then placed in parallel, so it looks like the six tubes in a similar The. Currently, the market-leading brands such as several LCD LG, Samsung, ViewSonic, Chun Jingjie mainstream products are produced with four lamp design, and six tubes of this design in the country currently only CHILI mini lcd module monitor in use.
           
That in the end what is good? We say no one is bad. Let me talk about two tubes, this technique is a relatively old, but it is also the most mature, followed by four lamps are developed out from two lamps. Some people think that two lamp brightness is uneven, in fact, this is not absolute. The top and bottom of each screen is a lamp, plus both optical devices can also be largely ensure uniform brightness, of course, the premise is better LCD workmanship.
           
From two out of the four lamp lamp design development, and its advantage is that the screen can be uniformly supplementary light, avoid screen gloomy existence of the phenomenon, but also can increase the expressiveness of color. In the viewing angle range, the naked eye longer feel differences in brightness. Six lamp allows more uniform brightness of the liquid crystal, it is very easy to understand. However, to be noted that the problem of heat lamps, six lamps are not only more than two out of the four lamp tube, and the two lamp more than a portion of the connection, so that the heat will cause the increase in . As we all know, the heat affects the life of the display, how to solve arising cooling, lamp life, low power consumption and other issues, which depends on the ability of manufacturers.
