Abstract: The present application provides a method and device of managing materials. In processes of manufacturing display devices, circuit board identifiers of flexible circuit boards and panel identifiers of display panels are obtained, and then the circuit board identifiers are bound with the panel identifiers. In a later stage, material management is performed on the display panels according to the circuit board identifiers. Based on the circuit board identifiers, sources of the display panels can be traced, so that no industrial inkjet printers are required and thus costs of material management can be reduced.

Abstract: The present invention provides an array substrate, a manufacturing method thereof, and a display panel. Orthographic projections of channel layers of two types of thin film transistors in a design of a driving circuit on the array substrate at least partially overlap, that is, two thin film transistors are stacked on top of each other, thereby facilitating a narrow border design of the display panel. In addition, a channel layer of one of the thin film transistors is an amorphous oxide semiconductor layer, which can reduce node leakage in the driving circuit, which is conducive to improving circuit stability and reducing power consumption.

Abstract: The disclosure provides a photo-etching compensation structure of an array substrate, including a substrate, a base layer, a light-sensitive layer, and a photo-etching compensation pattern layer disposed between the substrate and the base layer. The photo-etching compensation pattern layer includes a plurality of compensation patterns distributed in an array arrangement, and the compensation patterns change a thickness of the base layer along a thickness direction of the substrate, thereby making a thickness of the light-sensitive layer in an area corresponding to the compensation patterns less than a thickness of the light-sensitive layer in a corresponding area around the compensation patterns.

Abstract: A mini light emitting diode (LED) backlight panel is provided, which includes a plurality of backlight sub-panels in a docking way. A light-filling region is disposed between the arbitrary adjacent two backlight sub-panels. Fluorescent powder or quantum dots are filled in the light-filling region. The mini LED backlight panel emits light to excite material of the light-filling region to emit light. Secondly, adopting design solutions of large and small light emitting angles in mixed arrangement on different heights of the light emitting surfaces in the mini LED backlight panel, improving brightness on the splicing position, thereby improving quality of light emitted from the mini LED backlight panel, and meanwhile is advantageous for an ultra-thin design of the backlight module.

Abstract: The present application provides a liquid crystal display panel and a display device. Invalid pixels of the liquid crystal display panel include a test pixel. In this structure, when no tests are required, the test pixel is in an off state, and there is no voltage difference between a pixel electrode and a common electrode to cause rotation of liquid crystals. When a test is required, the test pixel is in an on state, and the pixel electrode is disconnected from the common electrode to cause a voltage difference, so that the liquid crystals are normally rotated.
