Abstract: The present invention provides a substrate and a method for monitoring positions of boundaries of a film layer disposed on a substrate. A plurality of sets of positioning units are provided in a non-display region of the substrate. Each set of the positioning units includes at least two primary positioning marks and corresponding primary positioning rulers. There are at least two secondary positioning marks and corresponding secondary positioning rulers disposed between the two adjacent primary positioning marks. The present invention determines a specific position of the boundaries of the film layer according to readings of the positioning rulers of the plurality of sets of positioning units corresponding to the boundaries of the film layer.

Abstract: According to an embodiment of the present disclosure, a display screen, a display device, and a method for manufacturing the display screen are disclosed. The display screen includes a display panel and a light bar. The light bar includes an array substrate and a plurality of light emitting elements, and a first gap is provided between two adjacent light emitting elements. A light absorbing layer is arranged in the first gap between at least two adjacent light emitting elements. By arranging the light absorbing layer, the side light of the light emitting elements can be partially absorbed, thereby reducing an emission angle of the light bar.
