Problems solved by technology

[0003] The traditional area backlight adjustment technology needs to use a large number of mini LEDs as the direct backlight, which requires a large number of mini LEDs as the backlight, which will greatly increase the cost. At the same time, the direct light source also increases the thickness of the fuselage
In addition, there are also manufacturers who use the design of double-layer liquid crystal cells to realize regional backlighting, but the above-mentioned existing design of double-layer liquid crystal cells will seriously affect the transmittance of the panel and increase the power consumption of the backlight

Abstract

The invention discloses a display device, a display terminal and a backlight adjusting method. The display device comprises a backlight module, a display panel and a backlight adjusting panel. The display panel includes a plurality of sub-display areas. The backlight adjusting panel includes a plurality of backlight control areas corresponding to the sub-display areas and a display medium layer that at least includes a first liquid crystal unit and a dichroic dye unit. The brightness of one sub-display area corresponding to each backlight control area can be controlled by controlling the electric field of each backlight control area. According to the invention, the function of adjusting the backlight intensity in different areas can be realized; and the penetration rate of the backlight adjusting panel can be well kept.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device, a display terminal and a backlight adjustment method. Background technique [0002] Regional backlight adjustment technology is a new technology to enhance the display effect of LCD monitors. It divides the image signal into several regions through the TV system, analyzes and calculates according to the image brightness of each region, and then automatically controls the brightness and darkness of the backlight in each region. Doing so can greatly improve the dark state of the LCD display and improve the contrast. [0003] The traditional area backlight adjustment technology needs to use a large number of mini LEDs as the direct backlight, which requires a large number of mini LEDs as the backlight, which will greatly increase the cost, and the direct light source also increases the thickness of the fuselage. In addition, there are also manufacturers u...
