A LCD having backlight and forelight function light guiding plate

Abstract

The invention discloses a liquid crystal display having a backlight and fore light function light conducting plate, mainly comprising cooperating light conducting plate and a liquid crystal display module and at least one illuminating source, wherein the light conducting plate is divided into a first light conducting portion and a second light conducting portion, a first deflector plate is arranged on the surface of the first light conducting plate far from the liquid crystal display module, a second deflector plate is arranged on the surface of the second light conducting plate in cooperation with the liquid crystal display module, for reflecting the light rays projected to the second display portion from the second light conducting portion.

Description

technical field [0001] The invention relates to a liquid crystal display with backlight and front light function light guide plate, especially relates to a single light guide plate combined with a liquid crystal display module, and cooperates with reflective plates respectively arranged on the light guide plate and the liquid crystal display module, so that the light guide plate and It is a liquid crystal display with front light and back light functions, and can achieve double-sided display effect. Background technique [0002] Figure 5 It is a structural diagram of a commonly used double-sided liquid crystal display. It is mainly provided with a backlight plate 82, 83 on both sides of the reflection plate 81, and then a backlight plate 82, 83 is provided on the side opposite to the reflection plate 81. A group of liquid crystal display modules 84, 85, so that each backlight board 82, 83 provides the backlight required by two groups of liquid crystal display modules 84, 85...

AI Technical Summary

Problems solved by technology

[0005] The double-sided liquid crystal display of above-mentioned structure, although only supply the required light of two liquid crystal display modules 92,93 through light source 94 and light guide plate 91, still need to use two groups of liquid crystal display modules 92,93, therefore, manufacturing cost It is still high, and it still consumes more power; the overall thickness cannot be effectively reduced, so it will also affect the design freedom of mobile phones or other electronic products.
