Problems solved by technology

[0003] In the prior art, in order to realize the capacitive touch function, touch driving electrodes need to be provided in the display device, but the touch driving circuit for providing touch driving signals to the touch driving electrodes is relatively complicated, which makes it difficult to realize the corresponding display device. Narrow frame; in addition, since the touch drive circuit has more signal input terminals, the touch drive circuit needs more output signals from an integrated control circuit (Integrated Circuit, referred to as IC), thereby increasing the cost of the IC

Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

[0042] In the prior art, in order to realize the capacitive touch function, the touch sensing electrodes are usually arranged on the side of the color filter substrate away from the array substrate, and the common electrodes arranged in the array substrate are multiplexed as touch driving electrodes, that is, In the display state, the common electrodes are used for receiving common voltage signals, and in the touch state, the common electrodes are used as touch driving electrodes for receiving touch driving signals.

Abstract

The invention discloses a drive circuit, an array substrate and a touch display device as well as a drive method thereof. A first gate electrode drive circuit and a touch drive circuit electrically connected with the first gate electrode drive circuit are arranged in the drive circuit; a secondary trigger signal output by a shifting register in the first gate electrode drive circuit is used as a grating signal of a touch selecting output unit in the corresponding touch drive circuit; correspondingly, the touch drive circuit is not needed to be equipped with a scanning unit for providing the grating signal for the touch selecting output unit, so that the touch drive circuit is relatively simple, not only can the touch display device easily realize narrow side frame, but also the output signal of IC and the cost of the IC can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving circuit, an array substrate, a touch display device and a driving method thereof. Background technique [0002] With the development of modern electronic technology, corresponding components will be installed in the display device to realize corresponding functions, such as capacitive touch function, etc., so as to bring convenience to users. [0003] In the prior art, in order to realize the capacitive touch function, touch driving electrodes need to be provided in the display device, but the touch driving circuit for providing touch driving signals to the touch driving electrodes is relatively complicated, which makes it difficult to realize the corresponding display device. Narrow frame; in addition, since the touch driving circuit has more signal input terminals, the touch driving circuit needs more output signals of an integrated control circuit (Integrate...
