The working principle and life of LCD

Viewing angles should be discussed from actual applications. Generally speaking, the six o&#;clock direction and the twelve o&#;clock direction are terms in the industry. To put it simply, the six o&#;clock direction is to look from the bottom up, and the twelve o&#;clock direction is to look from the top down. Correspondingly, the 3 o&#;clock and 9 o&#;clock directions that we seldom use are looking from left to right and looking from right to left. Generally speaking, we use the 12 o&#;clock and 6 o&#;clock directions the most.
Generally speaking, the viewing angle direction is determined by the use characteristics of the terminal product. For example, all kinds of meters and household equipment are all at 6 o&#;clock. But it should be noted that the viewing angles at 6 o&#;clock and 12 o&#;clock will look very close. But if you look closely, you will find that the difference is the depth of the font color. For example, a display with a viewing angle of 6 o&#;clock is very clear when viewed from the 12 o&#;clock direction, but it will appear slightly dim compared to the 6 o&#;clock direction.
Therefore, the viewing angle of the display screen needs to be determined according to the application of the terminal product. We generally suggest the corresponding perspective based on the customer&#;s product.
In addition, some customers require a wide viewing angle. Here, because it involves the difference of display types, liquid crystals and polarizers and so on. Let&#;s briefly summarize it. The viewing angle size from narrow to wide is TN, HTN, STN, FSTN, DSTN. The reason why we don&#;t talk about VA here is that it is special. Because it is white on a black background, its viewing angle is theoretically super wide. But it is not easy to compare directly. So we will not discuss it for the time being, but it is worth noting that VA is generally used in car display devices.
