Abstract

The invention discloses a display device, which comprises a backlight module, a first display panel and a second display panel, wherein the backlight module comprises a back plate, a lamp panel, a rubber frame, a diffusion plate and an optical film, the lamp panel is arranged on the back plate, a plurality of Mini LED lamp beads distributed in an array are arranged on the lamp panel, the rubber frame is arranged on the back plate and surrounds the lamp panel, and the second display panel, the first display panel, the optical film and the diffusion plate are stacked above the lamp panel. According to the invention, on the basis of the Mini LED technology, in combination with the overlapped screen design, the contrast ratio and the display image quality of the display device are further improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display device. Background technique [0002] Mini LED backlight technology refers to the LED array backlight technology that integrates high-density array distribution. Through the introduction of packaging, size reduction and mass transfer technology, the ability to control the backlight area is improved, and the optical distance of the backlight is reduced. Dynamic contrast backlight technology. [0003] Compared with OLED display devices, display devices using Mini LED technology have a higher dynamic range and a longer lifespan than OLED display devices, and become a future trend and development direction in the technical field of liquid crystal display devices. However, the contrast ratio of the display device adopting Mini LED technology is not as good as that of the OLED display device. Therefore, for those skilled in the art, how to further improve the ...
