Abstract

Disclosed are a display device comprising panel portions and a driving method thereof, which are capable of dividing the display panel into two or more panel portions and adding a touch mode between the display modes of each panel portion, thereby improving the frequency of the touch sensing or the touch report rate. The display device comprising panel portions and the driving method thereof can reduce the pulse width of the signals from 4H 8 phase to 2H 4 phase by using an oxide TFT and maintain or reduce the number of the signal lines applied to the gate driver of the partial display panel, thereby having the advantages in terms of the bezel.

First claim

What is claimed is:

1. A display device comprising a total of N gate lines and two or more panel portions, comprising:
a first panel portion comprising the 1st to N/2th gate lines driven during a display mode before a touch-sensing mode period;
a second panel portion comprising the (N/2+1)th to Nth gate lines driven during a display mode after the touch-sensing mode period;
an even gate driver comprising even gate circuit blocks (GIP blocks # 2 , 4 . . . , N) arranged at one…
