Embodiment Construction

[0017] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0018] see figure 1 , figure 1 It is a partial schematic diagram of a display device 1 according to an embodiment of the present invention. like figure 1 As shown, the display device 1 includes a display panel 10 and a backlight module 12 . In this embodiment, the display device 1 can be a liquid crystal display device, and the display panel 10 can be a liquid crystal display panel, but not limited thereto. The display panel 10 has an effective display area 100 with an effective display boundary 1000 . Generally speaking, a black light-shielding layer (Black Matrix, BM) is formed around the display panel 10, and the effective display area 100 is the area inside the black light-shielding layer, that is, the area where text and images can be displayed for users to w...

Abstract

The invention discloses a display device which comprises a display panel and a backlight module, wherein the display panel is provided with a valid display boundary; the backlight module comprises a frame, a light-guiding plate, a blue-ray light source and a quantum dot enhancing film; the frame is provided with a supporting part; the display panel is arranged on the supporting part; the valid display boundary is arranged a first preset distance away from the supporting part; the light-guiding plate is arranged in the frame; the light-guiding plate is located under the supporting part; the blue-ray light source is arranged in the frame and is located on one side of the light-guiding plate; the quantum dot enhancing film is arranged on the light-guiding plate; the distance of the quantum dot enhancing film exceeding the valid display boundary is a preset length; the preset length is greater than the first preset distance, so that the supporting part is partially overlapped with the quantum dot enhancing film.

Description

technical field [0001] The present invention relates to a display device and its backlight module, in particular to a display device and its backlight module which can effectively avoid light leakage. Background technique [0002] Due to the advantages of thinness, light weight, low power consumption, no radiation pollution, and compatibility with semiconductor process technology, liquid crystal display devices have been widely used in various electronic devices, such as notebook Computers, mobile phones, digital cameras, personal digital assistants, etc. The liquid crystal display device provides light to the display panel through the backlight module to display images. Generally speaking, a backlight module usually has a combination of a light source and an optical film. The light source is used to provide light, and the optical film combination is used to improve the optical characteristics of the light. The optical film included in the optical film assembly is, for ex...
