Self-contained touch panel, driving method and touch display device

Abstract

The invention provides a self-contained touch panel, a driving method and a touch display device. The self-contained touch panel comprises a switching unit and multi-row and multi-rank touch control electrodes arrayed in a matrix mode. Each touch control electrode of at least one row of touch control electrodes is connected with the same rank of touch control electrodes in the other row of touch control electrodes through the switching unit, wherein the switching unit is used for controlling the multi-row touch control electrodes to be connected into corresponding touch control signals in a time sharing way in the touch control time section; or each touch control electrode of the at least one rank of touch control electrodes are connected with the same row of touch control electrodes in the other rank of touch control electrodes through the switching unit, wherein the switching unit is used for controlling multi-tank touch control electrodes to be connected into corresponding touch control signals in a time sharing way in the touch control time section. According to the self-contained touch panel, the driving method and the touch display device, the number of channels between the touch control electrodes and the corresponding touch control signal lines can be reduced on the premise of determining the touch position, the dimensions and the production cost of the self-contained touch panel are reduced, and production of narrow borders can be facilitated.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a self-capacitive touch panel, a driving method and a touch display device. Background technique [0002] The self-capacitive touch control method has been widely used in the field of display devices, but under the premise of ensuring the touch resolution, there is a requirement for the size and width of the touch electrode. The existing embedded self-capacitive touch panels include Most of the touch electrodes in the world adopt a square (Block Pattern) design, and the embedded self-capacitive touch panel needs to use a large number of touch electrodes, and in the prior art, between each touch electrode and the corresponding touch signal line They are all connected through separate channels, so the number of channels between the touch electrodes and the touch signal lines also increases accordingly, which makes it impossible to meet the design requirements of narro...
