Problems solved by technology

However, in order to provide sufficient touch sensing time, the vertical blanking interval needs to be widened. In the case of a fixed frame rate (Frame Rate), the transmission rate of image data will need to be greatly increased, resulting in transmission lines, bus bars and display drivers. Increased requirements for overall systems such as chips
[0004] On the other hand, in the prior art, it is also possible to suspend the scanning line and data line driving sequence once or more in the frame of the display, so as to perform touch sensing during the suspension period. However, in this case, The display driver chip needs to add additional cache to temporarily store a large amount of image data, which will also cause system burden

Embodiment Construction

[0027] Please refer to figure 1 , figure 1 It is a schematic diagram of a touch display system 10 according to an embodiment of the present application. The touch display system 10 can be a display system with a touch function such as a smart phone or a tablet computer. The touch display system 10 includes a display 102 , a touch sensor 104 and a control unit 106 . The display 102 includes a display panel, wherein the display panel can be a gate driver on array (Gate Driver on Array, GOA) panel, or the display 102 can include a gate driver circuit (GateDriver) chip, so that the gate driver circuit can be used to drive the display panel The display 102 also includes a source driver circuit (Source Driver) chip to drive the display panel using the source driver circuit. The gate driver circuit chip and the source driver circuit chip can be integrated into a single chip, but this application does not This is the limit. The display 102 may further include a timing control circ...

Abstract

The invention discloses a touch control display driving method, which is used for a touch control display system, the touch control display system comprises a display and a touch control sensor, and the touch control display driving method comprises the following steps: transmitting a touch control scanning signal to the touch control sensor by a control unit, driving the touch sensor to carry out touch sensing in a time interval; wherein the time interval is located in a scanning line driving waveform of a gate electrode driving circuit of the display and located outside a plurality of data line driving waveforms of a source electrode driving circuit of the display. The driving method and the touch display system can provide good touch accuracy and reduce system cost.

Description

technical field [0001] The present application refers to a touch display driving method and its related touch display system, especially a driving method for improving the touch reporting rate and its related touch display system. Background technique [0002] With the progress and development of touch sensing technology, touch displays have been widely used in various electronic devices, such as mobile phones, tablet computers, personal digital assistants, notebook computers and other fixed or portable touch display devices, etc. , to replace traditional keyboards, mice and other input devices with touch sensing technology to achieve a more intuitive human-machine interface. However, as users have higher and higher requirements on the thickness and quality of existing electronic devices, manufacturers continue to develop touch displays with thinner and lighter appearances, high screen occupation, and higher touch accuracy. Therefore, touch displays It has gradually evolved...
