Abstract

The embodiments of the invention relate to a device and system used for simulating a light guiding plate, a backlight module and a test method. The device used for simulating the light guiding device comprises a light guiding substrate layer and an electroactive polymer layer, wherein the electroactive polymer layer is formed on the light guiding substrate layer and is configured to generate deformation according to network point arranging signals so as to simulate network points. According to the embodiments of the invention, the distribution of the network points of the light guiding plate can be simulated in real time without the production of a light guiding plate, so that the design and test assessment period of the light guiding plate is shorted, and the cost is saved.

Description

technical field [0001] Exemplary embodiments of the present invention relate to the fields of optical design and optical testing, and more particularly, to a device, system, backlight module and testing method for simulating a light guide plate. Background technique [0002] At present, the optical design and testing and evaluation methods of light guide plates in the prior art include: after arranging dots by optical design software (for example, mathcad), producing light guide plates with dots by printing, rolling, injection molding, etc.; and then Assemble the light guide plate and other components (such as film, light bar, plastic frame, back plate, etc.) into a backlight module; finally, perform optical testing and evaluation on the assembled backlight module. The disadvantage of the existing light guide plate optical design, test and evaluation system and method is that the light guide plate design, test and evaluation cycle is too long and the cost is high because the...
