During the first time period and the second time period, the second module transmits the signal at the third signal-input terminal to the third module to allow the signal at the fourth signal-input terminal to be transmitted to a second terminal of the first capacitor. During a third time period, the second module and the third module both block signal transmission. The first terminal of the first capacitor is connected to the signal-output terminal for output.

Abstract: The present disclosure provides a touch display device, including an upper substrate, a lower substrate, and a liquid crystal layer placed between the upper and lower substrates. The upper substrate includes a touch detection structure, and a plurality of pixel units arranged in a matrix. Each pixel unit includes a switch element and a pixel electrode. The lower substrate includes a common electrode and a reflection layer. The reflection layer is used for reflecting external light, and the external light refers to light from outside and sequentially emitting to the upper substrate and the liquid crystal layer, and then being incident to the reflection layer. In the touch display device, no whole or large area display electrode such as the common electrode is placed between the touch detection structure and the users. Thus, external touch signals will not be shielded, and the touch function can be better realized.
