A Substance Between Solid And Liquid
- Apr 25, 2018 -

The control IC, filters, and orientation films used in LCD manufacturing are related to the contrast of the panel. For the average user, a contrast ratio of 350:1 is sufficient, but the contrast level in the professional field cannot be satisfied. User needs. Compared to CRT displays that easily achieve 500:1 or higher contrast, only high-end LCD monitors can achieve this level. On the market, Samsung, Asus, LG, and other first-line brands can now achieve a 1000:1 contrast ratio. However, because contrast is difficult to measure accurately through the instrument, when it comes to picking, they still have to look at themselves.

LCD is a substance that is between the solid and the liquid. It cannot emit light itself. It requires the use of an extra light source. Therefore, the number of lamps is related to the brightness of the LCD. The earliest LCD monitors only had two tubes, one for the upper and the lower, and four lamps for the most popular models. Six lamps were used for the high-end models. The four lamp designs are divided into three types: one is that each of the four sides has one lamp, but the disadvantage is that a dark shadow appears in the middle, and the solution is to arrange the lamps in four rows from top to bottom. The last is the "U" type of display, which is actually the two lamps produced by the two lights in disguise. The six-tube design actually uses three lamps. The manufacturer bends all three lamps into a “U” shape and places them in parallel to achieve the effect of six lamps.
