Abstract:
A display panel comprises a display area and a peripheral area around the display area. The peripheral area comprises: an electroluminescent layer test region, a TFT test region and a plurality of lead-out lines. The electroluminescent layer test region comprises a plurality of thin film transistors having electroluminescent layers, a first test line connecting sources of the plurality of thin film transistors having electroluminescent layers, and a switch lead and a second test line connecting gates of the plurality of thin film transistors having electroluminescent layers. The TFT test region comprises a plurality of thin film transistors. Each of the plurality of lead-out lines is used for connecting a source-drain metal layer of one thin film transistor in the electroluminescent layer test region and a source-drain metal layer of one thin film transistor in the TFT test region.
Abstract:
An array substrate, a display panel and a display device are provided. The array substrate comprises: an active area, a package area and a drive circuit area, wherein the drive circuit area is located between the active area and the package area. A package metal layer is provided at the package area, and at least one groove structure is provided on a side of the package metal layer in a proximity to the drive circuit area.

Abstract:
The present invention belongs to the field of display technology, and particularly relates to an array substrate, a display panel and a display device. The array substrate comprises a light-emitting unit, a driving unit for driving the light-emitting unit, and a driving signal unit for providing a driving signal to the driving unit, the driving unit being provided in a central area of the array substrate, the driving signal unit being provided on at least one side of a marginal area surrounding the central area, wherein the light-emitting unit covers the driving unit and extends into the at least one side of the marginal area on which the driving signal unit is provided. The array substrate can have not only enlarged display area but also decreased bezel width, and also have improved aperture ratio of a pixel.
Abstract:
A pixel driving circuit and a driving method thereof, and an array substrate are provided. The pixel driving circuit includes a data line (Data), a gate line (Gate), a first power supply line (ELVDD), a second power supply line (ELVSS), a reference signal line (ref), a light emitting device (D), a driving transistor (T7), a storage capacitor (C1), a reset unit, a data writing unit, a compensating unit and a light emitting control unit. The pixel driving circuit can compensate and remove non-uniformity in displaying caused by variances in threshold voltage among driving transistors.
