Problems solved by technology
In the touch stage, when the I / O on the IC performs touch detection work, not only the corresponding I / O will send and receive pulse signals to the common electrode block 10 at the same time, but also the IC will uniformly process the received signals to achieve To determine the position of the touch point, it is obvious that each I / O sends pulse signals to and receives signals from all the common electrode blocks 10 on the array substrate at the same time, resulting in a significant increase in the power consumption of the display panel during touch detection.
Therefore, with the time-sharing effect of the touch phase and the display phase, the touch power consumption of the display panel increases significantly during the touch phase

The invention discloses a touch driving method, system, driving module and display device. The touch driving method includes: during the display stage of the display panel, acquiring the current display screen of the display panel in real time; extracting the information of the effective touch area of the current display screen; according to the information of the effective touch area, driving All corresponding touch electrodes in the effective touch area. The present invention extracts the information of the effective touch area from the current display screen, drives all the corresponding touch electrodes in the effective touch area according to the information of the effective touch area, adopts the local driving mode, reduces the amount of driving data, and shortens the processing time. time, the purpose of reducing touch power consumption in the touch stage is achieved, and the number of touch electrodes driven during touch driving is also reduced correspondingly, which improves the driving capability.
Description
technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch driving method, system, driving module and display device. Background technique [0002] With the rapid development of scientific and technological information products, electronic products tend to be light, thin, short and small, and display products are no exception. Among display products, liquid crystal display technology has the advantages of wide viewing angle, low power consumption, small size, zero radiation, etc., so it conforms to the current development trend of electronic products. [0003] Referring to FIG. 1( a ), it is a schematic diagram of an array substrate provided in the prior art. As shown in the figure, the array substrate includes common electrode blocks 10 arranged in a matrix (taking 16 blocks as an example, marked as RX1-RX16 in sequence), touch signal lines 11 arranged in one-to-one correspondence with the common electrode blocks ...
