Abstract: The present disclosure provides a display backplane and a preparation method therefor, and a display apparatus. The display backplane includes a plurality of display units, at least one display unit includes a pixel area and a light transmitting area, the pixel area is configured to perform image display and the light transmitting area is configured to transmit light; and in a plane perpendicular to the display backplane, the light transmitting area includes a substrate and a light transmitting structure layer arranged on the substrate, and the light transmitting structure layer is provided with light transmitting holes.

Abstract: The disclosed subject matter is a method to reduce film shedding from components internal to a process chamber. In one example, the method includes forming a dielectric film layer on each of a successive plurality of substrates within the process chamber, and, after a pre-determined number of the successive plurality of substrates have had the dielectric film layers formed thereon, forming an undoped-silicate glass (USG) film on the components internal to the process chamber to passivate accumulated levels of the dielectric film layers. Other devices and methods are disclosed.
