PC light diffusion plate experimental research device
PC light dispersion plate contains the main body of the PC light dispersion plate, and also contains at least one stopper and at least two mounting parts; the stopper is used to restrict the optical film, and each stopper is located on the PC light dispersion plate On the light-emitting side of the main body, each limiter has no overlap between the orthographic projection of the main body of the PC light dispersion plate and the performance area and overlaps with the peripheral area; the mounting parts are used to mount the lamp board, and each mounting part is located on the main body of the PC light dispersion plate On the light-incident side of the PC light diffusion plate body, each mount has no overlap with the display area and overlaps with the peripheral area on the contact surface of the PC light diffusion board body. At least a pair of comparable peripheral areas of the PC light diffusion board body are equipped with mounts. , At least one peripheral area of u200bu200bthe main body of the PC light dispersion board is not equipped with mounting parts. The backlight module, assembly techniques, and performance assembly belong to the performance technology platform, which can at least one-sidedly solve the problem that the existing direct-type backlight module is difficult to further float.
