Abstract: The present disclosure relates to a gate driving circuit applied to a foldable display panel comprising B display areas arranged in order. The gate driving circuit may include B gate driving subcircuits and a control circuit. Each of the gate driving subcircuits may correspond to one of the display areas and each of the gate driving subcircuits may comprise a plurality of stage gate driving units. The control circuit may be configured to, when the foldable display panel is in a full screen display state, control a type of an input signal in a last stage gate driving unit of a bth gate driving subcircuit to be the same as a type of an input signal in a first stage gate driving unit of a (b+1)th gate driving subcircuit, where B is an integer greater than 1 and b is a positive integer less than B.

Abstract: The application provides a wiring structure, a display substrate, and a display device, which pertain to the field of display technologies. The wiring structure includes a plurality of hollow units connected in series, and each of the hollow units includes a hollow area and a non-hollow area. The non-hollow areas of any two adjacent hollow units at least partially overlap, and the hollow areas thereof do not overlap. Compared with a conventional linear-type wiring structure, the wiring structure can release stress through the hollow area of the hollow unit in the process of bending, stretching, and twisting, so as to avoid breaking of the wiring structure which may result in failure of the device on the substrate that employs the wiring structure.

Abstract: The application discloses a wiring structure, a display substrate and a display device. The wiring structure provided includes a plurality of hollowed pattern strings, each hollowed pattern string including a plurality of hollowed patterns arranged sequentially in a length extension direction of the wiring structure, each hollowed pattern including a hollowed region and a non-hollowed region. The non-hollowed region of any hollowed pattern in a hollowed pattern string at least partially overlaps the non-hollowed region of a hollowed pattern in a further hollowed pattern string adjacent to the hollowed pattern string, and the hollowed regions of the hollowed patterns in the plurality of hollowed pattern strings do not overlap each other. The wiring structure is particularly adapted for flexible display.

Abstract: A pixel compensation circuit, a driving method thereof and a display device are provided. The pixel compensation circuit includes: a signal input unit, a driving unit, a light-emitting control unit, a first reset unit, a second reset unit, a first storage capacitor, a first switching transistor and a second switching transistor. When display data are written into the signal input unit, a signal write control line controls the first switching transistor to be switched on. The driving method of the pixel compensation circuit can be applied in the pixel compensation circuit. The pixel compensation circuit can be applied in an OLED display device.

Abstract: A display substrate and a method of manufacturing the same, and a display device, are disclosed. The display substrate includes a control portion and a color portion, the control portion and the color portion both including position aligning regions at corresponding positions and further including position aligning marks provided in the position aligning regions. The black matrix is located on top of the color portion and at least the position aligning marks in the color filter layer are formed in a hollowed-out structure. The position aligning marks has an increased level drop or height difference, such that more accurate position alignment may be achieved by identifying the position aligning marks based on height difference at edge of standard pattern.
