DISPLAY SUBSTRATE HAVING TOUCH FUNCTION, METHOD FOR DRIVING THE SAME AND DISPLAY APPARATUS
First Claim
1. A method for driving a display substrate having a touch function, comprising steps of:
- dividing touch driving electrodes comprised in the display substrate and parallel to gate lines into N portions, wherein each portion of the touch driving electrodes is arranged in a direction perpendicular to the gate lines, and N is a positive integer greater than or equal to 2; and
resetting pixels corresponding to an nth portion of the touch driving electrodes before a touch driving for the nth portion is started, so that the pixels have a same grey scale value, wherein n is a positive integer greater than or equal to 1 and less than or equal to N.

Abstract
The present disclosure provides in some embodiments a display substrate having a touch function, a method for driving the display substrate and a display apparatus. The method includes steps of: dividing touch driving electrodes included in the display substrate and parallel to gate lines into N portions, wherein each portion of the touch driving electrodes is arranged in a direction perpendicular to the gate lines, and N is a positive integer greater than or equal to 2; and resetting pixels corresponding to an nth portion of the touch driving electrodes before a touch driving for the nth portion is started, so that the pixels have a same grey scale value, wherein n is a positive integer greater than or equal to 1 and less than or equal to N.

11. A display substrate having a touch function, comprising a plurality of touch driving electrodes extending in a direction parallel to gate lines, wherein
the touch driving electrodes are divided into N portions, each portion of the touch driving electrodes is arranged in a direction perpendicular to the gate lines, and each portion of the touch driving electrodes is connected to a driving line, wherein N is a positive integer greater than or equal to 2; - and
pixels corresponding to an nth portion of the touch driving electrodes are capable of being reset to have a same grey scale value before a touch driving for the nth portion is started, so that liquid crystal molecules corresponding to the nth portion have a same deflection state, wherein n is a positive integer greater than or equal to 1 and less than or equal to N;
during a touch driving time period for the nth portion, the nth portion of the touch driving electrodes is applied with a touch driving signal; and
during a display scanning time period for the nth portion, the nth portion of the touch driving electrodes is applied with a common electrode signal. - View Dependent Claims (12, 13, 14, 15, 18, 19)
