    摘要： Display panel and display device, and fabrication methods are provided. The method for fabricating the display panel includes forming a protective layer at least on a bending region, the bending region being in a non-display region containing peripheral circuits of the display panel, to cover the peripheral circuits, and folding the display panel at the bending region towards a back surface of the display panel. When the display panel is folded at the bending region towards the back surface of the display panel, the protective layer coated on the bending region provides protection for the peripheral circuits formed on the surface of the bending region.

    摘要： The present disclosure relates to a device and a system for testing flatness. The device for testing flatness includes a base, a testing platform, and a ranging sensor. The testing platform is assembled on the base. The testing platform includes a supporting structure. The supporting structure is disposed on the side of the testing platform away from the base and is used to support a to-be-tested board. The structure matches the structure of the to-be-tested board. The ranging sensor is disposed on the side of the testing platform away from the base. After the to-be-tested board is placed on the testing platform, the ranging sensor is used to test distances between a number N of to-be-tested positions on the to-be-tested board and the ranging sensor, to obtain N pieces of distance information, and the N pieces of distance information are used to determine the flatness of the to-be-tested board, where N is an integer greater than 2. According to the embodiments of the present disclosure, the flatness of the glass substrate can be tested to improve the manufacturing process to reduce the flatness of the glass substrate, and avoid the problem that the glass substrate is easily broken when entering the subsequent process equipment and the process equipment is down.
