SHIFT REGISTER AND DRIVING METHOD THEREFOR, GATE DRIVE CIRCUIT AND DISPLAY APPARATUS
A shift register and a driving method therefor, a gate driving circuit and a display apparatus. The shift register comprises a trigger reset module, a pull-up module, a first capacitor and a pull-down module, and further comprises a denoising module. The pull-up module is used for pulling up a signal output from an output terminal of the shift register and a signal output from a transmission signal output terminal. The pull-down module is used for pulling down a signal output from the output terminal of the shift register and the signal output from the transmission signal output terminal. The denoising module is used for cutting off the connection path between the transmission signal output terminal and a second terminal of the first capacitor in a pull-down phase. The shift register, by providing the denoising module, makes it possible to prevent a coupling effect of the capacitor from making a transmission signal output from the transmission signal output terminal generate a sparkle noise or the like, when a voltage jump occurs at a pull-up node thereof, so that a shift transmission signal of the shift register is more stable, thereby making the signal output from the shift register more stable.
DISPLAY DEVICE
A display device includes a display panel, a gate driving circuit, and an image determination unit. The gate driving circuit includes a double gate transistor. The image determination unit outputs an image determination signal to a second control electrode of the double gate transistor. When the display panel displays a still image, the double gate transistor is turned on by the image determination signal so that each of gate signals outputted from stages connected in cascade to a stage including the double gate transistor among stages included in the gate driving circuit has a gate-off voltage.

Edge-aware synchronization of a data signal
A signal comprising a first edge and a second edge is received. The first edge of the signal is synchronized with a first clock and the synchronized first edge of the signal is passed to an output. The synchronization results in a delay of the first edge of the signal. The second edge of the signal is passed to the output. The passed second edge of the signal has a delay that is less than the delay of the first edge of the signal by at least one clock cycle of the first clock.
DISPLAY DEVICE
A scan line to which a selection signal or a non-selection signal is input from its end, and a transistor in which a clock signal is input to a gate, the non-selection signal is input to a source, and a drain is connected to the scan line are provided. A signal input to the end of the scan line is switched from the selection signal to the non-selection signal at the same or substantially the same time as the transistor is turned on. The non-selection signal is input not only from one end but also from both ends of the scan line. This makes it possible to inhibit the potentials of portions in the scan line from being changed at different times.
