Abstract

The invention provides a stacked screen display device and a control method of the display device. The stacked screen display device comprises a backlight module, a light control panel and a display panel which are sequentially stacked, the backlight module comprises a back plate, a light reflecting plate and a diffusion plate which are sequentially stacked, a plurality of light emitting units are arranged on the light reflecting plate, and a temperature sensor is arranged on the backlight module. The temperature sensor is used for detecting the temperature of the backlight module so as to compensate the display panel according to the temperature. According to the embodiment of the invention, the temperature detection of the backlight module is realized by arranging the temperature sensor, and the display panel is compensated according to the temperature detection result, so that the influence of the temperature on the display effect of the display panel is reduced, and the display effect is improved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a stack screen display device and a control method of the display device. Background technique [0002] The liquid crystal display device needs to be equipped with a backlight source, which may generate a lot of heat during operation, thereby causing the overall temperature of the display device to change, and the temperature change of the display device may cause the color temperature of the display device to change, affecting the display effect. SUMMARY OF THE INVENTION [0003] In a first aspect, an embodiment of the present disclosure provides a stacked-screen display device, including a backlight module, a light control panel, and a display panel that are stacked in sequence, and the backlight module includes a backplane, a reflector, and a diffuser that are stacked in sequence. , a plurality of light-emitting units are arranged on the reflector, and a tempe...
