Problems solved by technology

[0004] On this basis, as figure 1 As shown, since both sides of the light guide plate 101 can emit light, and they all belong to a large-angle light emission (that is, the direction perpendicular to the liquid crystal display panel is the normal direction, and the angle at which the light deviates from the normal direction is relatively large), so the side light source After the emitted light enters the light guide plate 101, it will form a large-angle incident light relative to the liquid crystal display panel; in this way, the large-angle incident light may be absorbed by the polarizer and the color film layer, resulting in the reflective LCD. The contrast is seriously low or even cannot be displayed normally

Abstract

The embodiment of the invention provides an optical module and a reflective display device and relates to the technical field of display. The optical module and the reflective display device can be used for improving the display effect under a dark environment and increasing the contrast ratio of a displayer. The optical module is arranged at a display side of a display panel and comprises a light guide plate, a light emitting unit arranged on the side surface of the light guide plate, and an optical film and a scattering film which are arranged between the light guide plate and the display panel, wherein the optical film is arranged close to one side of the light guide plate and is used for reducing the incident angle of incident light; the scattering film is arranged close to one side of the display panel and is used for scattering the incident light. The optical module is used for manufacturing a display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical module and a reflective display device. Background technique [0002] Reflective LCD (Liquid Crystal Display, liquid crystal display) is to realize the display function by reflecting light under the condition of sufficient ambient light by setting a reflective layer under the liquid crystal display panel (that is, the side where the liquid crystal layer is away from the light-emitting side). However, traditional reflective LCDs are highly dependent on ambient light and cannot display in low light conditions. [0003] In order to solve the above problems, in the prior art, a light guide plate is arranged above the liquid crystal display panel (that is, the side of the liquid crystal layer close to the light-emitting side), and a light-emitting unit is arranged on the side of the light guide plate, so that the reflective LCD has insufficient ambient light. It can also ...
