Abstract:
1. A display device comprising: a display panel; a plurality of pixels disposed on the display panel; a plurality of sensing units disposed on the display panel and adapted to generate a plurality of sensing signals in response to touches received by the sensing units; a sensing signal processor adapted to receive the sensing signals and generate sensing data in response to the sensing signals; and a touch detection unit having a first controller adapted to determine, based on the sensing data, whether or not a touch has been received by the sensing units and whether or not the sensing signals are in a desired range, and a second controller adapted to determine a position of the touch based on the sensing data and adapted to stabilize the sensing signals in the desired range; wherein the touch detection unit further comprises a register adapted to store values associated with a plurality of flags; and wherein the flags comprise an unstable state flag configured to indicate whether or not the sensing signals are in the desired range.
