A pixel structure, a display substrate and a display device are disclosed. The pixel structure comprises a plurality of first pixels, second pixels and third pixels. The first pixel comprises a first sub-pixel arranged at upper-right part and a second sub-pixel arranged at lower-left part. The second pixel comprises the second sub-pixel arranged at upper-right part and a third sub-pixel arranged at lower-left part. The third pixel comprises the third sub-pixel arranged at upper-right part and the first sub-pixel arranged at lower-left part. The second pixels are arranged at the right and upper sides of the first pixels. The third pixels are arranged at the right and upper sides of the second pixels. The first pixels are arranged at the right and upper sides of the third pixels. According to an embodiment, when an image having an oblique boundary, a transverse boundary and/or a vertical boundary is displayed, the phenomenon of color crispening will not occur because the first sub-pixels, the second sub-pixels and the third sub-pixels are arranged along the boundary of the image in a staggered way.

Pixel structure, display substrate and display device

A method and device for detecting a defect of a display panel, the method comprises steps of: connecting at least one electrical test pad on the display panel to a first detecting terminal, and connecting another at least one electrical test pad on the display panel to a second detecting terminal; providing a preset voltage between the first detecting terminal and the second detecting terminal; and, detecting whether magnitudes of currents passing through the first detecting terminal and the second detecting terminal within a predetermined time are less than a preset current threshold, and if not, then determining there is a defect on the display panel. The present disclosure can implement effective detection and interception of a progressive defect or badness in the display panel.

Method and device for detecting defect of display panel

The present invention provides a shift register and a method for driving the same, a gate driving circuit and a display device, the shift register includes a NOR gate circuit, a latch circuit and an output control circuit. First to fourth input terminals of the NOR gate circuit are connected to a clock control signal terminal, a signal input terminal, a high-level power supply terminal and a low-level power supply terminal, respectively, and an output terminal thereof is connected to a first input terminal of the latch circuit; second to fourth input terminals of the latch circuit are connected to the signal input terminal, the high-level power supply terminal and the low-level power supply terminal, respectively, and first and second output terminals thereof are both connected to the output control circuit, which is connected to the clock control signal terminal, the low-level power supply terminal and a signal output terminal.
