In the field of display technology, with the continuous advancement of input technology and display technology, the combination of commonly used liquid crystal displays and touch devices has become a major trend in the market development, and the experience of touch input is becoming higher and higher. For example, the pursuit of the original handwriting input effect, the electromagnetic screen technology has been widely used. In a conventional direct type LED backlit display, a light source is disposed on the back of the liquid crystal panel, and the electromagnetic panel is mounted on the liquid crystal panel. Due to the presence of some fine texture on the electromagnetic plate, the effect of the light source on the liquid crystal screen is seriously affected.
为解决上述技术问题，现有技术公开了一种直下式背光显示模组及显示设备，其将电磁膜片设置在发光结构及扩散板之间，通过扩散板的扩散作用使电磁膜片上的纹理模糊化，从而不会影响液晶屏的显示功能。由于电磁膜片具有一定的膨胀系数，电磁膜片的背面正对光源，光源散发的热量会使电磁膜片发生变形，温度降低时电磁膜片发生翘曲变形导致其不平整，从而严重影响液晶屏的触控效果。In order to solve the above technical problem, the prior art discloses a direct-lit backlight display module and a display device, which are disposed between a light-emitting structure and a diffusion plate, and are made on the electromagnetic film by diffusion of the diffusion plate. The texture is blurred so as not to affect the display function of the LCD screen. Since the electromagnetic diaphragm has a certain expansion coefficient, the back surface of the electromagnetic diaphragm faces the light source, and the heat emitted by the light source causes the electromagnetic diaphragm to be deformed. When the temperature is lowered, the electromagnetic diaphragm is warped and deformed, thereby causing unevenness thereof, thereby seriously affecting the liquid crystal. The touch effect of the screen.
