摘要： A display driving circuit, a method of driving a display driving circuit, a display panel, and a display device are provided. The display driving circuit includes a compensation circuit and at least one pixel circuit electrically connected to the compensation circuit. The pixel circuit is configured to receive a data compensation signal and control a current magnitude of a driving current flowing through a light-emitting element according to the data compensation signal, so as to apply an operating voltage to a first terminal of the light-emitting element. The compensation circuit is configured to receive the operating voltage and a data voltage and adjust the data compensation signal according to a difference between the operating voltage and the data voltage.

摘要： A photomask and an exposure method are provided. The photomask includes a photomask body including a first surface and a second surface opposite to each other; and a first light-transmissive region penetrating through the first surface and the second surface, wherein a light adjustment component is in the first light-transmissive region and configured to converge a first light beam incident onto the first surface to a second light beam emergent from the second surface, and a cross-sectional area of the first light beam sectioned by the first surface is larger than that of the second light beam sectioned by the second surface.
