Abstract: A multilayer light diffuser plate and a method for manufacturing the same are disclosed. The multilayer light diffusion plate comprises a main layer and a partially-transmissive and partially-reflective layer located under the main layer. The top surface of the main layer is the light-emitting surface, and the light-incident surface is the bottom surface of the partially-transmissive and partially-reflective layer. The partially-transmissive and partially-reflective layer comprises a plurality of first base material layers and a plurality of second base material layers stacked alternately. The materials of the first and second base material layers have different refractive indices. The partially-transmissive and partially-reflective layer formed by alternately stacking the first and second base material layers with different refractive indices is arranged on the light-incident surface of the light diffuser plate by means of extrusion, which is simpler and less expensive to manufacture.

Abstract: A light diffusion plate is configured to be assembled with a blue light source module having blue Mini LEDs to form a white light backlight module. The light diffusion plate is added with organic dyes with light-emission wavelength of 490-650 nm in order to convert the blue light into white light. The light diffusion plate is made by a foaming extrusion process and contains a plurality of micro-bubbles with a size of 60-400 ?m and a weight-reduction ratio of 15-25% for improving the uniformity of white light and resolving the MURA problem. The size of micro-bubbles is controlled by reducing the temperature of at the exit end of the T-die head, such that the wavelength of the white light emitted from the light diffusion plate can be narrower to achieve the effect of wider color gamut display.

Abstract: A touch display device is provided. The touch display device comprises a display panel and a touch panel disposed on the display panel. The touch panel comprises a touch substrate and a sensing electrode layer. The touch substrate has a first surface, a second surface and a third surface. The first surface is opposite to the third surface and away from the display panel. The second surface is connected to the first surface and the third surface, and has a stress fracture area adjacent to the first surface. The sensing electrode layer is disposed on the third surface.
