TFT ARRANGEMENT STRUCTURE

摘要

The present invention provides a TFT arrangement structure, comprising a first thin film transistor (T1) and a second thin film transistor (T2) controlled by the same control signal line; the first active layer (SC1) of the first thin film transistor (T1) and the second active layer (SC2) of the second thin film transistor (T2) are at different layers, and positioned to stack up in space, and the first source (S1) and the first drain (D1) of the first thin film transistor (T1) contact the first active layer (SC1), and the second source (S2) and the second drain (D2) of the second thin film transistor (T2) contact the second active layer (SC2); the bottom gate layer (Bottom Gate) of the first thin film transistor (T1) is positioned under the first active layer (SC1), and the top gate layer (Top Gate) of the second thin film transistor (T2) is above the second active layer (SC2). The TFT arrangement structure can reduce the space of the circuit arrangement to increase the flexibility of the circuit arrangement and satisfy the demands of the narrow frame and high resolution to the display panel.
