Driving display device and display driving method

Abstract

A display driving device includes a sensing electrode array, transmission lines, a light-emitting circuit, and a scan driver. The sensing electrode array includes first sensing electrodes arranged along a first direction. The number of transmission lines is first greater than a second number, whereby the second number is equal to the width of one of the first sensing electrodes divided by the spacing between the transmission lines. In a planar viewing angle, the transmission lines overlap with the sensing electrode array. The light-emitting circuit includes a light emitter and a switch coupled to the light emitter. The scan driver transmits a first scan signal from the scan signals via the transmission lines to the switch to turn it on, causing the light emitter to emit light in response to the first scan signal.
