Problems solved by technology
[0003] With the development of display panels, people are no longer only satisfied with conventional performance indicators such as large size and high definition of display panels, but also have more diverse requirements for the shape of display panels, so special-shaped display panels appear. Correspondingly, special-shaped backlight modules have also appeared. For example, there is a hole-digging area in the backlight module for placing the camera. At this time, if the backlight module still uses the original structure, the light emitted by the backlight module is likely to leak to the camera. position, thus affecting the optical effect of the camera

The invention discloses a display device, and relates to the technical field of display. The display device includes a display panel and a backlight module; the display panel includes a hollowed-out part, a display area, a first non-display area and a second non-display area, wherein the first non-display area surrounds the hollowed-out part, and the second non-display area surrounds the display area; the backlight module includes a first through hole, a containing frame, a reflection sheet and an optical film layer, wherein the first through hole corresponds to the hollowed-out part and penetrates through the backlight module in the depth direction of the hollowed-out part; the backlight module further includes a first shading film and a second shading film; the first shading film includes a first extension part and a second extension part which is connected with the first extension part and located inside the first through hole; the extension direction of the second extension part points to the main body of the containing frame from the first extension part; the second shading film includes a third extension part and a fourth extension part which is connected with the third extension part and located inside the first through hole; the extension direction of the fourth extension part points to the first extension part from the third extension part; the second extension part and the fourth extension part are attached to each other. In this way, the situation is effectively avoided that light of the backlight module leaks to the position corresponding to the first through hole.
Description
technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device. Background technique [0002] The backlight module is one of the key components of the liquid crystal display, which is used to provide sufficient brightness and evenly distributed light sources for the liquid crystal display panel, and its luminous effect will directly affect the visual effect of the liquid crystal display. With the continuous development of liquid crystal display technology, the application fields of liquid crystal displays, especially color liquid crystal displays, are also constantly expanding. Driven by the liquid crystal display market, the backlight industry presents a scene of prosperity. LCD (Liquid Crystal Display, liquid crystal display) is a non-luminescent display device, and it needs a backlight source to achieve the display function. The performance of the backlight will not only directly affect the image quali...
