Chenghao shares LCD viewing angle:
LCD is a kind of backlight display device, and its light is provided by the backlight behind the LCD module, which inevitably leads to the best viewing angle of LCD - face up. When you view from other angles, because the backlight can penetrate through the adjacent pixels and enter the human eye, it will cause color distortion. The undistorted range is the viewing angle of the LCD. The angle of view of LCD is divided into horizontal angle and vertical angle, and the horizontal angle is generally larger than the vertical angle. At present, as long as the horizontal perspective reaches 120 degrees and the vertical perspective reaches 140 degrees, it can meet the application needs of most users. The latest LCD panel is produced with wide viewing angle technology, which can reach 140 degrees up and down and 150 degrees left and right, reducing the inconvenience caused by small viewing angle. Of course, this performance for CRT display close to 180 degrees of view can not be compared, but for most applications, it is more than enough.
We also can according to your demand to customized your touch screen.
Such as:
1.Customized cover glass's shape,
2.Silk-printing color,
3.Touch with water,
4.With salt water touch,
5.With gloves and so on.
