What is the LCD module? What is the difference between LCD module and LCD panel? A: TN + film technology is to add a wide angle compensation film on the original basis. This compensation film can increase the viewing angle to about 150 degrees, which is a simple method and widely used in LCD. However, this technology can not improve the performance of contrast and response time. Maybe TN + film is not the best solution for manufacturers, but it is indeed the cheapest solution. Therefore, most manufacturers in Taiwan use this method to build 15 inch LCD.

What is the difference between LCD module and LCD panel?

this layer of compensation film can increase the viewing angle to about 150 degrees.
it is a simple and easy method, which is widely used in liquid crystal displays.
however, this technology can not improve the performance of contrast and response time.
maybe for manufacturers, TN + film is not the best solution, but it is indeed the cheapest solution, so most Taiwan manufacturers use this method to build 15 inch LCD.

IPS (in-plane-switching.
on board switching) technology, It is claimed that it can make the viewing angle of up, down, left and right reach 170 degrees.
although iPS technology increases the viewing angle.
however, using two electrodes to drive liquid crystal molecules requires more power consumption, This will increase the power consumption of liquid crystal display.
in addition, the fatal thing is that the response time of driving liquid crystal molecules in this way will be relatively slow.
.
MVA (multi-domain vertical alignment.
technology, The principle is to add protrusions to form multiple visible regions.
the liquid crystal molecules are not completely vertically arranged in static state.
after the voltage is applied, the liquid crystal molecules are horizontally arranged, In this way, MVA technology can improve the viewing angle to more than 160 degrees through each layer.
and provide shorter response time than IPS and TN + film.
this technology is developed by Fujitsu.
at present, Taiwan Qimei (a subsidiary of Qimei in mainland China) and Taiwan Youda are authorized to use this technology.
this paper introduces the development of this technologyYoupai's vx2025wm is the representative of this kind of panel.
the horizontal and vertical viewing angles are 175 degrees, basically without visual dead angle, and promise no bright spot; The viewing angle is divided into parallel and vertical viewing angles. The horizontal angle is centered on the vertical central axis of the liquid crystal, moving left and right to clearly see the angle range of the image.
the vertical angle is centered on the parallel central axis of the display screen.
moving up and down to clearly see the angle range of the image.
