The present invention relates to a pixel circuit comprising a first sub-pixel circuit and a second sub-pixel circuit, and the first sub-pixel circuit comprises a first light-emitting element which emits light in the first half of a frame period, and the second sub-pixel circuit comprises a second light-emitting element which emits light in the second half of the frame period.

Pixel circuit

The present patent application is related to the field of display devices, and provides a display device with panel test circuit the attenuation of data voltage signal could be reduced in the programs of testing pixel array. The display device comprises a plurality of first and second type of bonding pads located on the substrate and around periphery of the pixel array, and the panel test circuit has transistors, the transistors are disposed on the substrate and around periphery of the pixel array, a plurality of data lines of the pixel array are electrically connected with the second type of bonding pads one-to-one, and data detection signal applied to the first type of bonding pads is transmitted to the second type of bonding pads through the panel test circuit.

Display device with panel test circuit

The present disclosure provides a display device, a device and a method for gamma compensation. The device for gamma compensation includes: a flexure recording module, provided in a flexible display panel, and configured to acquire a flexure count of the flexible display panel; a parameter inquiring module, connected to the flexure recording module, and configured to inquire a corresponding gamma correction value from a comparison table involving a correspondence between flexure counts of the flexible display panel and gamma correction values according to the flexure count of the flexible display panel; and a voltage output module, connected to the parameter inquiring module, and configured to provide a gamma compensation voltage to the flexible display panel according to the gamma correction value.

Device and method for gamma compensation and display device

A dual-gate-driven lateral pixel arrangement structure includes two horizontally adjacent primary pixel regions having each three vertically adjacent secondary pixel regions forming a grid of six secondary pixel regions, and six thin-film transistors disposed in each of the six secondary pixel areas. The structure also includes two gate lines and three data lines crossing each other and electrically isolated from each other. Each data line is connected to the source of two thin-film transistors having the gate connected to a different gate line. The two gate lines are interposed between the three secondary pixel regions or arranged along a side or opposite sides of the primary pixel regions in a first direction. The three data lines are arranged between the primary pixel regions and along a side or opposite sides of the primary pixel regions in a second direction different from the first direction.
