Abstract

The invention discloses a curved light guide plate and a manufacturing method thereof. The curved light guide plate comprises an incidence surface, a first curved surface and a second curved surface. The first curved surface is parallel to the second curved surface and the first curved surface and the second curved surface are mounted on each side of the in-light surface. The first curved surface is provided with lattice points. Lights are reflected by the lattice points upon penetrating the incidence surface and shoots out from the second curved surface. The curved light guide plate is made of ultra clear glass and is made by curving ultra clear glass to be formed and constructing the lattice points on the first curved surface. The processed curved light guide plate is stable in performance and insusceptible to environmental changes of temperature and humidity under the conditions that the good area light and the light use efficiency are guaranteed. Accordingly, good dimensional stability to form stable and even backlights is guaranteed.

Description

technical field [0001] The invention relates to the field of light guide plates, in particular to a curved light guide plate and a manufacturing method thereof. Background technique [0002] For a curved display device, it is necessary to make the backlight module that provides the backlight source into a curved shape, and the curvature of the light-emitting surface depends on the curved shape of the display panel; therefore, the optical components in the backlight film assembly Parts also need to be machined into curved shapes. In the backlight module, the light guide plate is the main optical part, and in the prior art, the light guide plate is usually made of PMMA (polymethylmethacrylate: PolymethylMethacrylate) material, the curved light guide plate made of this material The disadvantage is that its shape and size will be affected by changes in ambient temperature and humidity; for example, when the humidity is too high, the volume of the curved light guide plate will e...
