Problems solved by technology

[0002] In the traditional double-sided liquid crystal display, due to the use of transmissive liquid crystal panels, two liquid crystal displays and corresponding backlights need to be applied, so the thickness is relatively thick and the power consumption is high, especially when displaying in bright outdoors. The display screen requires high brightness to see clearly, so the backlight of the display needs to have a high brightness, which will lead to high power consumption of the display, which is not conducive to energy saving and emission reduction; and the reflective display screen is located at the bottom of the liquid crystal display panel. It is installed with reflective material to replace the luminescent material of the transmissive display screen. When the ambient light is sufficient, it uses the light reflected by the mirror to illuminate the screen. The reflective LCD screen is more dependent on ambient light.
