Abstract
A touch detection method includes the following steps: (1). providing a touch display device, wherein the touch display device includes a plurality of LED units and a plurality of switches, each LED unit includes a LED and a photo sensor, and the switches are electrically coupled to the LED units; and (2). enabling the LED and a photo sensor coupled to the conductive one non-simultaneously during a conductive period of a conductive one of the switches. As a result, an influence of a touch detection of the photo sensor by a light emission of the LED could be reduced.
