Problems solved by technology

[0004] However, due to the fixed divergence angle of the supplementary light source, the light emitted by the supplementary light source will naturally propagate in two directions after total reflection in the light guide plate, so there is a certain amount of light emitted from the reflection surface of the light guide plate and directly Injected into human eyes, causing damage to human eyes

Abstract

The invention relates to a light guide plate, a light guide plate assembly and a display device. The light guide plate comprises a light guide plate main body, the light guide plate main body is provided with a reflecting surface and a light emitting surface which are oppositely arranged, and a light incident surface adjacent to the reflecting surface and the light emitting surface, the light incident surface enables light from a light source to enter the light guide plate main body, and the light is totally emitted in the light guide plate main body; the light guide plate further comprises a number of reflecting parts which are positioned in the light guide plate main body, and each reflecting part is provided with a reflecting and scattering surface which reflects light and emits the light from the light emitting surface; the light guide plate further comprises a semi-transparent and semi-reflective film layer located on the reflecting and scattering surface, and the semi-transparent and semi-reflective film layer is used for reflecting and transmitting light, so that the light reflection quantity of the reflecting and scattering surface can be increased, more light can be emitted from the light emitting surface of the light guide plate, and the number of light emitted from the reflecting surface of the light guide plate is reduced; therefore, the damage to human eyes when a reflective display device uses a supplementary light source for display under the condition of insufficient ambient light can be reduced, and the utilization rate of light emitted by the light source is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a light guide plate, a light guide plate assembly and a display device. Background technique [0002] At present, according to different types of light sources (backlight, external light) used by the display devices, the display devices can be classified into three types: transmissive, reflective and transflective. Wherein, the reflective display device realizes display by reflecting ambient light incident into the reflective display device. Since the reflective display device does not need an additional backlight module to provide backlight for its display, the reflective display device has received extensive attention and applications. [0003] However, reflective display devices are highly dependent on ambient light. In the case of sufficient ambient light, the display is clear and bright, but in the case of insufficient ambient light, the display effect drops a l...
