A flat panel sensor and a flat panel detector are provided on the basis of a top-gate TFT structure. The flat panel sensor comprises a base substrate, and a top-gate TFT and a storage capacitor that are formed on the base substrate; the storage capacitor includes a first conductive layer, a second conductive layer disposed in opposition to the first conductive layer, a third conductive layer for output of an electric signal, and a ground line; the first conductive layer is directly connected to a drain electrode and an active layer of the top-gate TFT, the second conductive layer is directly connected to the ground line, and the third conductive layer is connected to the first conductive layer through a via hole.

Flat panel sensor and flat panel detector

The embodiment of the present invention discloses a touch unit, an array substrate, a liquid crystal cell substrate and a touch display device. The touch unit comprise a plurality of touch sub-units, each of which comprising a sensor thin film transistor (TFT), an sensing capacitor, a reading induction line and a memory capacitor, the capacitance of the memory capacitor being less than that of the sensing capacitor. Due to the memory capacitor is added to stabilize the voltage of the sensor TFT, the interference of noise upon the voltage of the sensor TFT is reduced, thus effectively improving the signal stability of the touch unit.
