Double-vision display module

Abstract

The invention relates to a double-vision display module which comprises a backlight source and a display panel, wherein the display panel comprises a display screen and a shading grating; the shading grating which is positioned between the display screen and the backlight source comprises a base plate, a reflective film layer and a shading film layer, wherein the reflective film layer is formed on the base plate, and the shading film layer is formed on the reflective film layer; a slit is formed in the shading film layer for light to emit, and the light emitting part and the non light emitting part of the shading film layer are proportionally and periodically distributed; and the shape and the structure of the reflective film layer are the same as those of the shading film layer. Light rays which are irradiated by the backlight source on the reflective film layer are reflected to the backlight source, so that recycling of light energy is realized, the light emitting rate of the display module is increased, and the light emitting brightness of the display module is guaranteed on the premise that the brightness of the backlight source does not need to be enhanced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a dual-view display module capable of simultaneously displaying two images. Background technique [0002] Dual-vision display means that a display screen presents two different images at different angles at the same time. The screen is an entertainment screen such as a movie, so that it can guide the driver's route and at the same time make the passengers happy physically and mentally without affecting the driver. [0003] At present, the most commonly used dual-view display technology is grating occlusion. The viewer can only see the even pixel columns of the display screen illuminated by the backlight through the grating slits on one side of the display screen, and can only see the pixel columns on the other side. To the odd pixel columns of the display screen illuminated by the backlight through the grating slits, so as long as the even pixel columns and odd pixel columns of...

Problems solved by technology

However, since this dual-view display structure needs to emit backlight energy in two directions separately, the brightness of each viewpoint is reduced accordingly, and the aperture ratio of the grating is usually only about 20%, which blocks a large amount of light, making the display The brightness is greatly reduced. Usually, in order to meet the display brightness, the brightness of the backlight will be greatly increased, which will increase the energy consumption of the entire dual-view display module.
