Problems solved by technology

[0005] Existing display modules include a backlight module, a casing, etc. The backlight module includes a light guide plate and a reflector. The light source is usually arranged on one side of the backlight module, but the optical path between the side of the backlight module away from the light source and the casing is relatively short. , resulting in more light here, which makes the local brightness of the display module brighter, so when viewed at a large viewing angle, light leakage is prone to occur, which reduces the display effect

Abstract

The invention provides a display module and an electronic device. The display module comprises a backlight module, a liquid crystal display panel and a casing; the backlight module comprises a light guide plate and a light source arranged in one side of the light guide plate; the casing accommodates the backlight module and the liquid crystal display panel, at least the inner surface of the firstside of the casing is provided with a light-absorption layer, position of the light-absorption layer corresponds to position of the light guide plate at least, and the first side is opposite to the light source and far from the light source. The display module and electronic device can avoid light leakage, and improve the display effect.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of display technology, in particular to a display module and an electronic device. [0003] 【Background technique】 [0004] With the continuous development of the display module, the frame of the display module is getting narrower and narrower, so it is widely used in electronic products. [0005] Existing display modules include a backlight module, a casing, etc. The backlight module includes a light guide plate and a reflector. The light source is usually arranged on one side of the backlight module, but the optical path between the side of the backlight module away from the light source and the casing is relatively short. , resulting in more light here, which makes the local brightness of the display module brighter, so when viewed at a large viewing angle, light leakage is prone to occur, which reduces the display effect. [0006] Therefore, it is necessary to provide a display module and an electronic de...
