Abstract:
1. A field sequential liquid crystal display device, wherein a pixel structure of the device comprises: a first thin film transistor, a second thin film transistor, a third thin film transistor, a fourth thin film transistor, each having a gate, a source, and a drain; a frame buffer capacitor; a storage capacitor; and a holding capacitor; wherein the gate of said first thin film transistor is connected to a gate line, the source of said first thin film transistor is connected to a data line, and the drain of said first thin film transistor is connected to the source of the second thin film transistor; the source of said second thin film transistor is connected to an end of the frame buffer capacitor, and the drain of said second thin film transistor is connected to the drain of the third thin film transistor; the other end of said frame buffer capacitor and the source of the third thin film transistor both are connected to the drain of the fourth thin film transistor, and the source of the fourth thin film transistor is grounded; and the drain of said second thin film transistor is also connected to an end of the storage capacitor, the other end of said storage capacitor is grounded, and said storage capacitor and said holding capacitor are connected in parallel, wherein the gate of said second thin film transistor is connected to a video synchronization signal, the gate of said third thin film transistor is connected to a zero clearing signal, and the gate of said fourth thin film transistor is connected to a grounding control signal.
