摘要： Embodiments of the present disclosure provide a timing controller, a display device, and a display driving method. The timing controller includes a first digital gamma correction circuit, a second digital gamma correction circuit, and a microcontroller. The microcontroller is configured to count output frames in response to receiving a video signal; determine, based on the counting, whether a current output frame needs to be data voltage polarity inverted; responsive to determining that the current frame needs to be data voltage polarity inverted, using a first digital gamma correction table read from the first digital gamma correction circuit to calculate corrected data voltages; responsive to determining that the current frame does not need to be polarity inverted, using a second digital gamma correction table read from the second digital gamma correction circuit to calculate corrected data voltages; and output the corrected data voltages to a display.

摘要： A voltage control circuit comprises a sampling sub-circuit and a control sub-circuit. The sampling sub-circuit is configured to detect a potential difference between an output voltage and an input voltage to obtain a first voltage and output the first voltage to the control sub-circuit. The control sub-circuit is configured to compare a magnitude of the first voltage with a first voltage threshold, if the first voltage is less than the first voltage threshold, output the input voltage as the output voltage, and, if the first voltage is greater than or equal to the first voltage threshold, superimpose and output the input voltage and a bootstrap voltage as the output voltage.
