DISPLAY DEVICE AND METHOD OF DRIVING THE SAME
First Claim
1. A method of driving a display device comprising a plurality of pixels, a plurality of sensing units, and a plurality of sense data lines to which the plurality of sensing units are connected, comprising:
- reading sense signals from the sense data lines;
determining from the sense signals whether or not the display has been touched;
determining from the sense signals the number of touches, and generating X-axis and Y-axis position data based on the sense signals; and
,when a plural number of touches have occurred, determining whether the plurality of touches are sequentially generated and a touch position thereof based on the X-axis and Y-axis position data.

Abstract
A method of driving a display device having a plurality of pixels, a plurality of sensing units, and a plurality of sense data lines to which the plurality of sensing units are connected, includes: reading sense signals from the sense data lines; determining whether or not the display has been touched and the number of touches, generating X-axis and Y-axis position data based on the sense signals, and determining, when the quantity of touches is plural, whether a plurality of touches are sequentially generated, and the touch position of each.

11. A display device comprising:
-
a display panel having a plurality of pixels; a plurality of first sense signal lines extending in a first direction in the display panel and transferring first sense signals; a plurality of second sense signal lines extending in a second direction in the display panel and transferring second sense signals; a plurality of first sensing units that are connected to the first sense signal lines and that generate the first sense signals according to a touch with the display panel; a plurality of second sensing units that are connected to the second sense signal lines and that generate the second sense signals according to the touch with the display panel; and a touch determination unit for determining the touch or not and the quantity of touches, and generating X-axis and Y-axis position data of the touch based on the first sense signals and the second sense signals that are transferred through the first sense signal lines and the second sense signal lines, respectively, and determining, when the quantity of touches is plural, whether a plurality of touches are sequentially occurred, and the touch position based on the X-axis and Y-axis position data. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
