Embodiment 1

[0074] refer to figure 1 , which shows a flow chart of a driving method in an embodiment of the present invention, which may specifically include the following steps:

[0075] Step 101 , adjust the load mode of the TDDI chip according to the signals of the touch electrodes on the touch panel read by the reading module.

[0076] In the embodiment of the present invention, the reading module in the TDDI chip reads the signals of the touch electrodes on the touch panel, and adjusts the load mode of the TDDI chip according to the read signals of the touch electrodes on the touch panel.

[0077] Among them, there are two load modes of the TDDI chip, which are heavy load mode and light load mode; heavy load mode refers to the mode when the display panel and touch panel are used at the same time, light load mode refers to the use of the display panel, but Mode when the touch panel is not used.

[0078] For example, when a user touches a touch display device to refresh a webpage, it...

Embodiment 2

[0091] refer to Figure 4 , which shows a specific flow chart of a driving method in an embodiment of the present invention, which may specifically include the following steps:

[0092] Step 401, when the TDDI chip is in the heavy load mode and it is detected that the signal of the touch electrode on the touch panel read by the reading module has not changed within a preset period of time, the TDDI chip The load mode is adjusted to light load mode.

[0093] In the embodiment of the present invention, when the TDDI chip is in the heavy load mode, the control reading module reads the signals of the touch electrodes on the touch panel. When the signal of the touch electrode does not change, the load mode of the TDDI chip is adjusted to the light load mode.

[0094] It should be noted that the preset duration can be set manually, such as 1s, 10s, etc.; the signal of the touch electrode on the touch panel read by the reading module within the preset duration does not change means: ...

Embodiment 3

[0150] refer to Figure 8 , shows a structural block diagram of a driving device according to an embodiment of the present invention.

[0151] The driving device 800 of the embodiment of the present invention is applied to a touch display device, the touch display device includes a touch display panel and a TDDI chip connected to the touch display panel, and the touch display panel includes a display panel and A touch panel, the display panel includes a plurality of pixels arranged in an array, the touch panel includes a plurality of touch electrodes arranged in an array, and the TDDI chip includes a driving module and a reading module; the driving device 800 include:

[0152] The load mode adjustment module 801 is configured to adjust the load mode of the TDDI chip according to the signals of the touch electrodes on the touch panel read by the reading module;

[0153] The first display duration adjustment module 802 is configured to control the drive module to adjust the di...

Abstract

The invention provides a driving method and device and a display device, and relates to the technical field of display. The method comprises: reading the signal of the touch electrode on the touch panel by the reading module; adjusting the load mode of the TDDI chip; when the TDDI chip is in a heavy load mode, the TDDI chip being in a heavy load mode; controlling the driving module to adjust the display duration of each row of pixels in the display panel into a first display duration according to the first clock signal, when the TDDI chip is in a light load mode, switching on the light load mode; and controlling a driving module to adjust the display duration of each row of pixels in the display panel into a second display duration according to the second clock signal, wherein the second display duration is greater than the first display duration, so that the display duration distributed to each frame of image by the TDDI chip in a light load mode is improved, the touch duration distributed to each frame of image is reduced, and the touch time is not idle. Moreover, charging and discharging of each row of pixels are more sufficient, and the display effect of the touch display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method, device and display device. Background technique [0002] With the continuous development of display technology, touch display devices have been widely used. Usually, the touch panel and display panel in touch display devices are independently controlled by two chips. In order to improve the integration of touch display devices , TDDI (Touch and Display Driver Integration, touch and display driver integration) chip came into being. [0003] The TDDI chip integrates the functions of the touch chip and the display chip into a single chip. The TDDI chip usually has two load modes, namely the heavy load mode and the light load mode. The data volume of the touch signal that needs to be processed in the heavy load mode Larger, and the amount of touch signal data that needs to be processed in the light load mode is small. In the two load modes, the TDDI chip a...
