The OLED display panel comprises: a substrate comprising a display area and a non-display area; a pixel driving circuit disposed on the display area, wherein the pixel driving circuit comprises a reset signal input end and a cathode signal input end; and a cathode signal trace arranged on the non-display area, wherein the cathode signal trace is electrically connected to both the reset signal input end and the cathode signal input end.

OLED display panel and OLED display device

A touch display panel at least includes a plurality of touch signal lines, the touch signal lines includes a first type touch signal line and a second type touch signal line, and a distance between a first end of the first type touch signal line and a touch integrated circuit is less than a distance between a first end of the second type touch signal line and the touch integrated circuit. The first type touch signal line includes a single sub-signal line, and the second type touch signal line includes at least two sub-signal lines.

Touch display panel

The disclosure provides a polyimide (PI) substrate and a manufacturing method thereof. The PI substrate includes a first area and a plurality of second areas, wherein the second areas are spaced apart from each other in the first area, and the PI substrate includes a glass substrate and a plurality of PI layers disposed on the glass substrate.

PI substrate and manufacturing method thereof

A display panel, a folding method thereof, and a display device are provided. The display panel includes a display region, a non-display region, and a bending region. Side edges of the bending region include bending points, the bending points are disposed in the bending region, and the side edges are concaved toward an interior of the bending region at the bending points. During folding, the bending points on the side edges of two sides form at least one guiding axis, which makes the display panel easier to bend, and folding precision and folding effect are good.

Display panel, folding method thereof, and display device

A display panel has a non-display area comprising a GOA wiring area is provided. The display panel includes GOA wirings disposed in the GOA wiring area, and an electrostatic shielding unit, disposed at least corresponding to the GOA wirings of part of the GOA wiring area. The electrostatic shielding unit is configured to prevent the GOA wirings from being damaged by static electricity.

Display panel
