1. An active liquid crystal display panel comprising:
a pixel array comprising a plurality of pixels; a gate driving circuit for driving M first scan lines, wherein M is a natural number; a data driving circuit for converting display data into a plurality of data voltages and driving N data lines, wherein an output signal of each data line is used for charging/discharging a pixel corresponding to the data line to a predetermined voltage according to a data voltage of the plurality of data voltages; and an analog buffer coupled to the gate driving circuit comprising:
M buffer circuits, each buffer circuit comprising:
a P-type thin film transistor having a first terminal, a second terminal directly coupled to a first scan line, and a third terminal directly coupled to a second scan line corresponding to the first scan line, the second scan line being configured to control turning-on and turning-off of a switch coupled to a pixel; andan N-type thin film transistor having a first terminal directly coupled to the second scan line, a second terminal directly coupled to the first scan line, and a third terminal; anda regulator comprising:
a first diode having an anode terminal configured to receive a first reference voltage, and a cathode terminal directly coupled to the first terminal of the P-type thin film transistor; anda second diode having a cathode terminal configured to receive a second reference voltage, and an anode terminal directly coupled to the third terminal of the N-type thin film transistor. |
