Abstract: Embodiments of the present disclosure provide a display substrate having a display region and a frame region. The display substrate includes a plurality of display pixels and a plurality of dummy pixels arranged in an array; the display pixels are distributed in the display region; the dummy pixels are distributed in the frame region. Each display pixel includes a first pixel electrode and a first common electrode; and a first voltage difference exists between the first pixel electrode and the first common electrode. Each dummy pixel includes a second pixel electrode and a second common electrode; and a second voltage difference exists between the second pixel electrode and the second common electrode. A difference between the first voltage difference and the second voltage difference is less than a set value. Embodiments of the present disclosure further provides a display panel and a display apparatus.

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.
