SOURCE DRIVING CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/200864
Kind Code:
A1
Abstract:
A source driving circuit and a driving method therefor, and a display device. The source driving circuit comprises: an input sub-circuit (11), configured to receive a data signal (INPUT), a first control signal (SW1), and a second control signal (SW2), and provide the received data signal (INPUT) according to the first control signal (SW1) and the second control signal (SW2); a first latching sub-circuit (12), configured to receive the first control signal (SW1) and the second control signal (SW2), and latch the data signal (INPUT) provided by the input sub-circuit (11) according to the first control signal (SW1) and the second control signal (SW2); a transmission sub-circuit (13), configured to receive a third control signal (SW3) and a fourth control signal (SW4), and transmit the data signal (INPUT) latched by the first latching sub-circuit (12) according to the third control signal (SW3) and the fourth control signal (SW4); and a second latching sub-circuit (14), configured to receive the third control signal (SW3) and the fourth control signal (SW4), and latch the data signal (INPUT) from the transmission sub-circuit (13) according to the third control signal (SW3) and the fourth control signal (SW4); the transmission sub-circuit (13) and the second latching sub-circuit (14) being configured to be that the second latching sub-circuit (14) is switched off when the transmission sub-circuit (13) is switched on, and the second latching sub-circuit (14) is switched on when the transmission sub-circuit (13) is switched off.
