Display Device Having Partial Panels and Driving Method thereof

摘要

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 8phase to 2H 4phase 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.

主权项

1. A touch sensing display device comprising:
a display panel having a common electrode and gate lines, the display panel including a first panel portion having a first subset of the gate lines and a second panel portion having a second subset of the gate lines; and gate drivers to drive the gate lines, wherein during a single display frame period the display device operates in the following modes during distinct periods of time:
a first display mode during which a common voltage is applied to the common electrode and the gate drivers drive the first subset of the gate lines;a first touch sensing mode during which at least one first touch driving pulse is applied to the common electrode and touch is sensed across both the first panel portion and the second panel portion, the first touch sensing mode being after the first display mode;a second display mode during which the common voltage is applied to the common electrode and the gate drivers drive the second subset of the gate lines, the second display mode being after the first touch sensing mode; anda second touch sensing mode during which at least one second touch driving pulse is applied to the common electrode and touch is sensed across both the first panel portion and the second panel portion, the second touch sensing mode being after the second display mode.
