Abstract: This invention provides a composite diffuser plate comprising a light-emitting layer for emitting light, a middle layer for guiding light, and a light-entering layer for entering light, being sequentially stacked downwardly. At least one surface of the middle layer is provided with an array of curved protrusions. Refractive indexes of the light-emitting layer, the middle layer and the light-entering layer are gradually increased. This invention further provides an ultra-thin direct type backlight module. In the composite diffuser plate of this invention, in addition to a gradual increase in refractive indexes of the light-emitting layer, the middle layer and the light-entering layer, the middle layer is provided with a microstructure having curved protrusions, which further enhances diverging effect of emitting angle. The direct-light TV can increase a light-emitting area with a small OD value, and thus improves a LED Mura problem, realizing a slim direct-light TV and enhancing market competitiveness.

Abstract: A temperature regulating liquid crystal panel packaging box is provided, including a box body and a temperature regulator, the box body includes an accommodating part, the temperature regulator is arranged in the accommodating part to release or absorb heat as an outside temperature changes to keep an internal temperature of the box body balanced. In the liquid crystal panel packaging box, by disposing a temperature regulator on the periphery of the box body, when the outside temperature changes, the temperature regulator may spontaneously absorb heat or release heat to regulate the temperature inside the box body, thereby reducing the temperature difference between the inside and outside the box and preventing the water vapor in the air from condensing inside the box.

Abstract: The present disclosure provides a LCD screen, including a liquid crystal panel, a first functional layer disposed on an array substrate of the liquid crystal panel, a quarter-wave plate and a polarizing layer sequentially stacked on the first functional layer, wherein the array substrate has a metal wire that reflects ambient light sequentially passing through the polarizing layer, the quarter-wave plate and the first functional layer and striking the surface of the metal wire; an included angle is between the optical axis of the quarter-wave plate and the absorption axis of the polarizing layer so as to block the ambient light reflected by the metal wire in the polarizing layer. The angle between the optical axis of the quarter-wave plate and the absorption axis of the polarizing layer of the present disclosure is 30-60°, so that the ambient light entering the polarizing layer is blocked in the polarizing layer.

Abstract: Disclosed are a display panel and manufacturing method thereof and a display device. The display panel includes a first substrate, a second substrate, a chip on film, and a shading array layer. The end of the first substrate extending beyond the second substrate forms a bonding end and the chip on film is bonded onto inner side of the bonding end. The inner surface of the first substrate is provided with metal signal wires located in non-pixel area. The shading array layer is located in the non-pixel area and completely shades the wires. Because the first substrate faces the viewer and the chip on film is bonded onto the inner side of bonding end, a bezel-less design is attained. The patterned shading layer forms a pattern corresponding to the metal signal wires to shade the wires for weakening lights reaching the wires and reducing reflectiveness of wires.
