The LCD Module Visual Angle
Mar 24, 2017

LCD viewing Angle is a headache problem, when the back light by partial plate, liquid crystal and orientation layer, the output light is directional. That is to say, most of the light is vertical shoot from the screen, so watch from the perspective of a large LCD, cannot see the original color, even only see all white or all black. IN order to solve this problem, manufacturers are also set out to develop wide technology, so far there are three of the more popular technology, respectively is: TN + FILM, IPS (IN - PLANE - SWITCHING) and MVA (MULTI - DOMAIN VERTICAL alignMENT).

TN + FILM, on the basis of the technology is in the original, increased a layer of wide Angle compensation FILM. This compensation film viewing angles can be increased to 150 degrees, is a kind of simple and feasible method, a large number of applications in the liquid crystal display. But this technique does not improve the contrast and response time, such as performance, perhaps the makers, TN + FILM is not the best solution, but it is the cheapest solution, so most Taiwanese manufacturers are using this method to build 15 inch LCD monitor.
