A display panel, a method for driving the display panel and a display apparatus are provided. The display panel includes a light-emitting element and a pixel circuit, the pixel circuit includes: an enable signal terminal being a pulse width modulation signal, including a plurality of first active levels spaced in one frame light-emitting duration, a first inactive level being between two adjacent first active levels, where the enable signal is capable of driving the light-emitting element to emit light during a first active level period; a reset signal terminal including at least one second active level and one second inactive level in one frame light-emitting duration, the second active level being in a first inactive level period, and the first active level being in a second inactive level period, where the reset signal is capable of resetting the light-emitting device during a second active level period.

Display panel and method for driving display panel, and display apparatus

The present disclosure relates to an OLED display substrate including a base substrate, a thin film transistor array layer and a planarization layer on the base substrate, and an anode, a pixel definition layer, a cathode, and a light emitting layer on a side of the planarization layer away from the base substrate, the pixel definition layer defining pixel regions, the light emitting layer being located on a side of the pixel definition layer away from the base substrate. The display substrate further includes a light guide that is in contact with the light emitting layer and is used to lead out light from the light emitting layer, so as to test the led-out light and adjust light emission.

OLED display substrate and manufacturing method thereof, OLED display device, and brightness compensation method

The present disclosure relates to a method for manufacturing an OLED light emitting device, an OLED light emitting device, and an OLED display device. The method for manufacturing an OLED light emitting device according to an embodiment of the present disclosure includes forming a pixel defining layer on a substrate, wherein the pixel defining layer comprises a lyophilic material or a lyophobic material and the pixel defining layer comprises a plurality of openings which are spaced apart from each other; forming an anode layer on the substrate and in each opening; adding a preset solvent having a property opposite to that of the lyophilic material or the lyophobic material of the pixel defining layer in an OLED film layer ink; and ink-jet printing the OLED film layer ink on the anode layer and in each opening to form an OLED film layer.
