    Abstract: 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.

    Abstract: The present disclosure relates to a method of preparing a display substrate. The method may include forming a pattern layer on a base substrate; forming a planarization layer on the pattern layer, the planarization layer comprising a host material and a hydrophilic material and a hydrophobic material mixed in the host material; treating the planarization layer so that the host material reacts with the hydrophilic material to form a hydrophilic polymer, the host material reacts with the hydrophobic material to form a hydrophobic polymer, and the planarization layer is delaminated to form a first sub-planarization layer and a second sub-planarization layer; and cleaning the planarization layer with a cleaning solution that reacts with the hydrophobic polymer to remove at least part of the first sub-planarization layer. The first sub-planarization layer includes the hydrophobic polymer, and the second sub-planarization layer includes the hydrophilic polymer.

    Abstract: Embodiments of the present invention provide a beam splitter, a laser generator and an excimer laser annealing apparatus, which relate to field of display technology, and reduce probability of pollution of the beam splitter to some extent and increase homogeneity of the laser beam that is passed through the beam splitter. The beam splitter includes a transmission region configured as a through-hole and a reflective region arranged at a periphery of the through-hole, wherein the through-hole is configured to be transmitted by a first laser beam that is received; and the reflective region is configured to reflect the first laser beam that is received. The beam splitter may be used in a laser generator to perform a scanning annealing process.
