Display device and driving method thereof

Abstract

A display device and a driving method thereof are provided. The display device includes a pixel array and a data driving circuit. The data driving circuit is coupled to pixel data lines in the pixel array. The data driving circuit includes a data driving chip and a data multiplexer. The data multiplexer includes a plurality of multiplexing circuits. Each multiplexing circuit includes a first transistor, a bootstrap capacitor, a diode, and a second transistor. The first transistor is coupled to one of the pixel data lines in the pixel array and one of the chip data lines. The bootstrap capacitor is coupled between a second terminal and the control terminal of the first transistor. The diode is coupled between the control terminal of the first transistor and a first control line. The second transistor is coupled to a reference voltage terminal, the control terminal of the first transistor, and a second control line. The data multiplexer may be combined with gate bootstrap circuits or pixel voltage bootstrap circuits to form a system-level low-voltage driving solution.
