Abstract: The application provides an array substrate, a display panel, and a display device. The display panel comprises the support plate and the array substrate. The backlight surface of the flexible driving circuit substrate of the array substrate is bonded to the support plate in the display area. The area where the flexible driving circuit substrate is provided with the gate driving circuit and the data driving circuit is bent and attached to the other surface of the support plate. The light emitting surface of the display panel only has a display area capable of displaying pictures, which alleviates the problem that the existing display panel cannot fully display.

Abstract: A display device provided includes a display panel, a first backlight module, a second backlight module, a light sensor, and a viewing angle adjusting component. The first backlight module includes an optical element, and the viewing angle adjusting component is disposed corresponding to a display sensing area. When the optical element is in a fog state, the viewing angle adjusting component reduces an exit angle of backlight. When the optical element is in a transparent state, external light enters the light sensor through the viewing angle adjusting component and the first backlight module, which improves uniformity of backlight viewing angle.

Abstract: The present invention teaches a method of having a built-in polarizer in a LCD panel, a LCD device, and a LCD device manufacturing method. The method of having built-in polarizer in a LCD panel taught by the present invention uses a nano imprinting technique to form a wire-grid built-in polarizer. The built-in polarizer, when applied to a LCD device, is able to resolve the QDCF-based product's difficulty in controlling light's on and off and to enhance backlight utilization efficiency. The built-in polarizer has a sandwich structure where a metallic wire grid layer is sandwiched between a first inorganic protection layer and a second inorganic protection layer, preventing the metallic wire grid layer from erosion by oxidation and enhancing the operation life of the built-in polarizer.
