Abstract

The invention provides a light guide plate, an optical module and an all-reverse display device, relating to the technical field of display and being capable of increasing the light of the light guide plate emitting to the reflection area of a display panel and further realizing high contrast display. The light guide plate includes a light incident plane, a light emitting plane, and a first plane opposite to the light emitting plane, the light guide plate further includes screen dots arranged on the first plane, the screen dots are in the shape of a groove and at least enable the light incident parallel to the light emitting plane to be emitted out at the angle of 60-90 degrees with respect to the light emitting plane.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate, an optical module and a full-reflection display device. Background technique [0002] With the development of display technology and the rapid increase in demand for outdoor wear, outdoor display technology has received more and more attention. [0003] The total reflection display device has attracted much attention as a new type of display device. It can be used with the front light guide plate and the light source to realize the display at night or in low brightness. When the ambient light is bright enough, only the ambient light can be used. Display is realized, thereby reducing the power consumption of the display device when displaying to a certain extent. [0004] However, if figure 1 As shown, most of the light that exits from the light guide plate 10 and enters the display panel 30 is absorbed by the black matrix (Black Matrix, BM) 31 in the displ...
