Embodiment 1

[0036] as attached figure 1 -Attached Figure 4 As shown, the first embodiment of the present invention provides a touch panel, the touch panel includes: a display module 1;

[0037] a control module, used to acquire touch information and calculate display data information 3, where the display data information 3 includes coordinate data 31 and its corresponding display data 32;

[0038] The driving module is configured to acquire the display data information 3 and drive the pixel units corresponding to the coordinate data 31 of the display module 1 to refresh and display the information corresponding to the display data 32 .

[0039]Specifically, the touch panel proposed in this embodiment can be applied to the field of active pen touch, and is based on the Memory in Pixel (MIP) display technology. In the MIP display mode, a fixed Voltage (a certain voltage), no need for regular refresh, and low-power display can be achieved. The display module 1 includes a plurality of sig...

Embodiment 2

[0056] as attached Figure 5 -Attached Image 6 As shown, the second embodiment of the present invention provides a driving method for a touch panel, and the driving method for the touch panel includes: S1: Acquire touch information, and calculate display data information 3, where the data information includes coordinate data 31 and its corresponding display data 32;

[0057] S2 : Acquire the display data information 3 , and drive the pixel units corresponding to the coordinate data 31 of the display module 1 to display the display data 32 .

[0058] Specifically, when the active pen touch panel performs a continuous touch operation, the active pen can emit a driving signal, and the control module of the touch panel can acquire touch information of each touch point, and the touch information includes the coordinate data 31 and Display data 32, wherein the coordinate data 31 is the position of the pixel unit corresponding to the touch point of the active pen, and the display ...

Embodiment 3

[0070] The third embodiment of the present invention provides a display device including the above-mentioned touch panel.

[0071] Specifically, the display device may be an electronic device with a touch panel, such as a notebook computer and a tablet computer, and may be used with an active pen.

[0072] According to the above list, an embodiment of the present invention provides a display device, the touch information of each point when the active pen touches the touch panel can be obtained through the control module of the touch panel, and the touch information includes coordinate data 31 and display data , the drive module of the touch panel can drive the pixel unit at the corresponding position of the coordinate data 31 to display the information corresponding to the display data, and only refresh the pixel unit at the coordinate position to realize the single-point data refresh display of the pixel unit, avoiding the use of the current one-by-one The redundant display d...

Abstract

The invention discloses a touch panel, a driving method thereof, and a display device, which relate to the technical field of touch display, and solve the problem that the current driving structure of the display screen is progressive scan display, which causes the touch and display of the active pen to be out of synchronization. The display lags behind the touch, which affects the user experience. The main technical scheme of the present invention includes: a display module; a control module for acquiring touch control information and calculating display data information, where the display data information includes coordinate data and corresponding display data; a driving module for The display data information is acquired, and the pixel unit corresponding to the coordinate data of the display module is driven to refresh and display the information corresponding to the display data.

Description

technical field [0001] The present invention relates to the technical field of touch display, and in particular, to a touch panel, a driving method thereof, and a display device. Background technique [0002] With the development of display technology and the continuous expansion of application scope, higher requirements are put forward on the power consumption of display devices. The Memory in Pixel (MIP) display technology can achieve a lower refresh rate, so it can have lower power consumption. [0003] In the current active pen touch display field, since the drive structure of the display screen is progressive scan display, the system segment needs to calculate and transmit redundant display data during display, and the LCD display device needs to perform progressive scan on the display area to turn on This will inevitably lead to a corresponding time difference from the touch response to the display, that is, the touch display time is prolonged, and the touch and displ...
