What is the angle of view of the LCD display? How to distinguish?
 



I believe that people who have been in contact with LCD for a long time know that when talking about LCD display, there will be a lot of parameter problems, and one of them seems to be not the focus but it is very important, that is, "lcd display angle"!


This problem seems to be very simple, and many business people talked about it when they talked about it.


But for the customer, it may not be so professional, you don't say that he may have to find it when it is used, then the trouble can be big!

Then, today I will talk about the seemingly simple but not negligible range of LCD display angles.



The lcd display viewing angle range means that the user can clearly observe the angle of all the content on the screen from different directions.


Since some lcd display sources have a certain directionality after being refracted and reflected, the color distortion will occur when viewed beyond this range.



LCD is divided into TN perspective and IPS perspective, so what is the difference?

Big head? It doesn't matter, please continue to look down.


The TN perspective is the common perspective we often say. The English name is TN Mode LCDs.

The TN viewing angle parameters in the industry are: 6H, 9H, 3H, 12H. It is commonly referred to as the 6 o'clock direction, the 9 o'clock direction, the 3 o'clock direction, and the 12 o'clock direction.


Take a wall clock as an example - explain the direction of the view, 6 points for the bottom view, 3 points for the left view, 9 points for the right view, and 12 points for the top view.
According to the angle, it is 45° left and right. Although the angle of view is not so good, but many occasions are applicable, and the yield is high.


This point, in our Tianzheng product specification book, has a profound manifestation:



 

The IPS perspective, as the name suggests, is In-Plane Switching or Super-TFT.


By aligning the alignment of the liquid crystal molecules parallel to the glass substrate, the viewing angle can be expanded to 170 degrees, just as the viewing angle of the CRT monitor is as good.
However, this technique also has disadvantages because the alignment of the liquid crystal allows its electrodes to be placed on only one of the two glass sheets, unlike the TN mode.
