Assignee: TCL CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 9:
10. A display device, comprising a display panel and a driving circuit connected to the display panel, the driving circuit comprising:
at least one source driving chip, connected to the display panel;
a timing controller, connected to the at least one source driving chip; and
a power management circuit chip, comprising a first end and a second end, wherein the first end is connected to the timing controller and the second end is connected to the at least one source driving chip, and the power management circuit chip outputs a data driving voltage and a gamma voltage to the at least one source driving chip,
wherein the source driving chip determines whether a voltage difference between the data driving voltage and the gamma voltage is within a predetermined range, and based on a result of the determination the driving circuit decides whether to adjust the data driving voltage and the gamma voltage,
wherein the source driving chip determines whether the voltage difference is within the predetermined range, and if yes, the source driving chip outputs a driving signal to the display panel; if no, outputting, by the source driving chip, a voltage difference signal to the timing controller, transmitting, by the timing controller, a control signal, and adjusting, by the driving circuit, the driving voltage and/or the gamma voltage based on the control signal.
