Abstract

The present application relates to the technical field of display. Disclosed are a touch panel and a touch device. Third conductive patterns in a second touch trace layer are connected to first conductive pattern groups by means of openings in a first insulating layer, and the third conductive patterns are also connected to second conductive patterns. Fourth conductive patterns in the second touch trace layer are connected to the second conductive patterns by means of first via holes in a touch insulating layer and the first insulating layer, and the fourth conductive patterns are further connected to touch electrodes. The touch insulation boundary of the touch insulating layer is located in gaps between the third conductive patterns and the fourth conductive patterns, and therefore even if there is residual conductive material at the touch insulation boundary during the preparation of the second touch trace layer, a short circuit between different fourth conductive patterns cannot be caused, and a short circuit between different third conductive patterns cannot be caused. Thus, short circuits between different connection interfaces can be avoided, thereby ensuring the touch panel yield.

Abstract

Provided are a display panel, a driving method for a pixel circuit in a display panel, and a display device, relating to the technical field of display. In the pixel circuit, a switching circuit, a control circuit and a driving circuit can cooperate with each other to transmit a light-emitting driving signal to a light-emitting element on the basis of different signals such as a switching control signal, a reference power supply signal, a gate driving signal, and a light-emitting control signal, to drive the light-emitting element to emit light. Therefore, by flexibly configuring a switching control signal, when the light-emitting element is driven to emit light, the switching circuit can control a reference power line to be decoupled from a first node, so that the potential variations at a control end and an output end of the driving circuit are equal, thereby avoiding offset of a light-emitting driving signal transmitted by the driving circuit, and ensuring that the light-emitting element is reliably driven to emit light.

Abstract

A shift register unit and a driving method therefor, a display driving circuit, and a display apparatus, belonging to the technical field of display. In the shift register unit, under the control of a clock signal provided by a first clock end (CKn) and a clock signal provided by a second clock end (CB), an input control circuit (01) controls connection and disconnection of an input end (IN_n) and an input node (Q_n).

Thus, by means of flexibly configuring the clock signals and the reset control signal, the shift register unit can be made to output to the output end (OUT_n) a light-emitting control signal matching a P-type transistor and/or an N-type transistor in the pixel, and can also reliably reset the outputted light-emitting control signal when a display panel (10) is powered on or powered off, thereby ensuring good driving flexibility and abundant driving modes, and also ensuring good dependance on startup and shutdown and a good driving effect.
