Abstract

The invention discloses a noise scanning method, a noise scanning device and a touch screen, and belongs to the technical field of touch screens. The noise scanning method comprises the following steps: performing touch scanning on the touch screen; performing noise scanning on the touch screen, wherein touch scanning and noise scanning are carried out simultaneously; noise scanning comprises the following steps: performing noise scanning on a plurality of Tx or performing noise scanning on a plurality of Rx; obtaining positions of all touch units on the touch screen according to a touch scanning result and a noise scanning result. According to the noise scanning method and the noise scanning device, the problem of poorer touch scanning effect when the touch scanning and display scanning are carried out on the an embedded touch screen simultaneously is solved; the touch scanning effect is enhanced. The touch screen is used for touch scanning of the embedded touch screen.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a noise scanning method and device, and a touch screen. Background technique [0002] The embedded touch display screen is formed by integrating the touch screen and the display screen, and the touch screen is embedded in the display screen. The touch screen includes a plurality of touch units arranged in an array. The touch screen is provided with a plurality of horizontally arranged touch driving lines Tx and a plurality of vertically arranged touch sensing lines Rx. One touch driving line Tx corresponds to a row of touch units, and one touch sensing line Rx Corresponds to a column of touch units. [0003] When the embedded touch screen realizes the touch function, it is necessary to input the touch scan signal to the embedded touch screen to perform touch scanning to obtain the position of each touch unit on the embedded touch screen; When the touch display screen real...
