Problems solved by technology

However, after the quantum dot enhanced film is cut and sealed by laser, a quantum dot failure area of ​​1.3~1.5mm will be produced. This failure area will prevent the blue light emitted by the blue LED from effectively exciting the quantum dots, resulting in blue light leakage in the liquid crystal display area. phenomenon, which in turn causes the liquid crystal display device to have a visual difference in perception

Embodiment Construction

[0029] see figure 1 , the display device 100 according to the embodiment of the present invention includes a display panel 10 and a backlight module 20 . The display device 100 may be a liquid crystal display device, and the display panel 10 may be a liquid crystal display panel, but not limited thereto. The display panel 10 includes an upper polarizer 11 , a lower polarizer 12 and a color filter 13 disposed between the upper polarizer 11 and the lower polarizer 12 . It can be understood that the display panel 10 also includes structures such as a liquid crystal layer and a TFT substrate. In this embodiment, a black matrix (Black Matrix, BM) 132 for light shielding is formed around the color filter 13 . The display panel 10 is divided into a main display area 110 and a peripheral area 111 by the black matrix 132 . It can be understood that the color filter 13 also includes red (R), green (G) and blue (B) color layers for color representation.

Abstract

Provided is a display device. The display device comprises a display panel and a backlight module. The display panel comprises a main displayarea and a peripheral area. The backlight module comprises a blue light source, a light guide board and a quantum dot enhancement film. The blue light source is arranged on one side of the light guide board. The quantum dot enhancement film is arranged on the upper surface of the light guide board. The distance from the edge of the main display area to one end, close to the blue light source, of the quantum dot enhancement film is larger than or equal to pre-set distance. Therefore, no blue light leaks during observation when the display panel is viewed at a viewing angle larger than or equal to a pre-set viewing angle.

Description

technical field [0001] The invention relates to a display device. Background technique [0002] Currently, liquid crystal display devices on the market tend to have low energy consumption and high color saturation, and liquid crystal display devices must provide a light source through a backlight module to display images. Backlight required for liquid crystal display devices. For the purpose of reducing energy consumption and thinning the design, most backlight sources in the prior art use light emitting diodes (Light Emitting Diode, LED). Based on the purpose of improving the optical characteristics and visual effects of the light source, the optical film group usually includes a plurality of optical films, such as prism sheets, diffusion sheets, light guide plates, etc., but the optical structure of the backlight module in the prior art is usually difficult to achieve effective Improve color saturation and reduce energy consumption. [0003] In order to effectively impr...
