Abstract
Official abstract text for this publication.
The present invention relates to a display device having a touch sensor in which the touch sensor is driven in a period which has a small noise component from the display device to reduce influence from the noise for minimizing a touch error; and a method for driving the same. The display device having a touch sensor includes a display panel, a panel driving unit for driving the display panel, a timing controller for controlling driving timing of the panel driving unit, a touch sensor integrated with the display panel attached thereto or built therein, and a touch controller for driving the touch sensor in a no noise period excluding a period in which the noise is generated periodically from the display panel by using at least one synchronizing signal from the timing controller, and calculating touch coordinates from a signal from the touch sensor and forwarding the touch coordinates.
First claim
Opening claim text (preview).
What is claimed is: 1. A display device having a touch sensor, comprising: a display panel; a panel driving unit configured to drive the display panel; a timing controller configured to control driving timing of the panel driving unit; a touch sensor integrated with the display panel attached thereto or built therein; and a touch controller configured to: drive the touch sensor in a no noise period, excluding a period in which the noise is generated periodically from the…
