Abstract: The embodiment of the present application provides a display panel. The display panel includes a driver substrate and a light emitting device bonded to and disposed on the driver substrate. The driver substrate includes a driver circuit and a first power line. The first power line includes a conductive pad. The light emitting device includes a first soldering pad and a second soldering pad. The first soldering pad overlaps and is bonded to the conductive pad. The second soldering pad is electrically connected to the driver circuit. The embodiment of the present application overlaps and bonds the opaque first soldering pad to the first power line, particularly overlaps and bonds the first soldering pad to the conductive pad. Therefore, an overlapping area between the first soldering pad and the first power line is increased.

Abstract: A display panel is provided by the present application. The display panel includes a display area and a non-display area. The display panel includes a plurality of power signal lines. Each of the power signal lines includes a power signal input line arranged on the non-display area, a power signal main line and a plurality of power signal sub-lines arranged on the display area. The power signal input line is connected to the power signal main line. At least part of the power signal sub-lines are directly connected to the power signal main line. a width of an input end of the power signal main line is wider than a width each of the power signal sub-lines. The width of the input end of the power signal main line is increased by an embodiment, which can avoid the power signal main line damage due to large current.

Abstract: The present disclosure relates to a composite substrate adapted for manufacturing a flexible display screen. The composite substrate includes a base substrate, a sacrificial layer, and a flexible layer. The sacrificial layer is located on the base substrate. The flexible layer is located on the sacrificial layer. The sacrificial layer is an inorganic layer which contains hydrogen element and is semi-transparent. The present disclosure further provides a method for manufacturing a flexible display screen, comprising: depositing a sacrificial layer on a base substrate, the sacrificial layer is an inorganic layer, the inorganic layer contains hydrogen element and is semi-transparent; forming a flexible layer on the sacrificial layer; forming electronic components on the flexible layer; and irradiating the sacrificial layer by a laser beam to cause the hydrogen element in the sacrificial layer to form hydrogen gas bubbles, so as to separate the base substrate and the sacrificial layer.
