摘要： A thin film transistor structure of a pixel is provided. In the present invention, a first metal layer serves as a gate electrode, and the gate electrode includes an extending gate electrode portion. A second metal layer includes a drain electrode partially and respectively overlapping the gate electrode and the gate electrode portion with the amorphous silicon layer interposed therebetween so as to form a first parasitic capacitor and a second parasitic capacitor. The total capacitance of the first parasitic capacitor and the second parasitic capacitor is invariable to withstand deviation caused by vibration of the machine in the photolithographic process, so that undesired effects in the liquid crystal display panel such as mura and flicker can be reduced.

摘要： A pixel structure includes a scan line, a data line, a gate electrode, a semiconductor layer, a source electrode, a drain electrode including a comb-shaped part surrounding the source electrode and a connecting part, and a pixel electrode electrically connected to the drain electrode. The scan line and the data line are arranged intersectedly and electrically insulated from each other. At least a portion of the source electrode and the drain electrode are disposed on the semiconductor layer. At least one branch of the comb-shaped part extends outside one side of the gate electrode to form a protrusion part. The connecting part extends from the comb-shaped part beyond the other side of the gate electrode. The protrusion part and the connecting part aligned with the margin of the gate electrode have a first width and a third width respectively, wherein the first width substantially equals to the third width.

摘要： A pixel circuit for a liquid crystal display panel includes a capacitor unit, a voltage-regulating mechanism, a first switching member, and a second switching member. The liquid crystal display panel includes a plurality of scan lines and data lines. The voltage-regulating mechanism is coupled to the first and second liquid crystal capacitors thereby enabling the first and second liquid crystal capacitors to be configured with different voltages when a voltage is applied to the capacitor unit. The first switching member is coupled to the capacitor unit, one of two corresponding scan lines, and one of two corresponding data lines. The second switching member is coupled to the second liquid crystal capacitor, the other of two corresponding scan lines.
