Problems solved by technology

[0004] In the existing liquid crystal display panel, in the edge part of the quantum dot film layer, the quantum dots in the quantum dot film layer are damaged due to edge cutting and the quantum dots near the edge are easily oxidized, so that the edge position of the backlight quantum dot film layer The increase of blue light and the decrease of green light and red light will cause the image displayed at the edge of the display area of ​​the LCD panel corresponding to the backlight emitted by the backlight module to be bluish, which will affect the image display quality

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] like figure 1 as shown, figure 1 It is a schematic diagram of the principle that the image displayed at the edge position of the existing liquid crystal display panel is bluish. In the quantum dot film layer 11 of the backlight module, there are a plurality of quantum dots 12 uniformly distributed. The quantum dots 12 can be excited by blue light to emit red light and Green light, which is mixed with blue light to form white light, is used for the whit...

Abstract

The invention discloses a display device, which comprises a display module and a backlight module, which further comprises a blue light source device and a quantum dot film layer. The quantum dot film layer is triggered by blue light to generate red light and green light. The display module comprises a display region and a border region surrounding the display region. The display region comprises a first region and a second region surrounding the first region; the display region has a plurality of pixel units in array configuration. For pixel units located in the second region, blue light transmittance is smaller than that of the red light and that of the green light. This invention makes the transmission rate of the blue light of the display unit in the edge position of the display region relatively smaller than that of the red light and the green light, thus prevents the display from being comparatively blue, guaranteeing the display quality.

Description

technical field [0001] The present invention relates to the technical field of image display, and more specifically, to a display device. Background technique [0002] With the development of science and technology, more and more display devices are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable tool for people today. . [0003] The main component of the display device to realize the display function is the display panel. Liquid crystal display panels are one of the mainstream displays today. The liquid crystal display panel includes a display module and a backlight module. In the existing liquid crystal display panel, the backlight module includes a quantum dot film layer excited by blue light to generate green light and red light. When the liquid crystal display is displayed, the quantum dots in the quantum dot film layer are excited by the blue LED to generate red light and g...
