Abstract
Official abstract text for this publication.
This application discloses a display device driving method and a display device. The driving method includes steps of: synchronously starting a backlight circuit, a timing control circuit and a power circuit; outputting a first signal after the timing control circuit is initialized; outputting a second signal after the power circuit is started; and controlling a gate driver to output a drive signal according to the first signal and the second signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A display device driving method, comprising steps of: synchronously starting a backlight circuit, a timing control circuit and a power circuit; outputting a first signal after the timing control circuit is initialized; outputting a second signal after the power circuit is started; and controlling a gate driver to output a drive signal according to the first signal and the second signal; wherein the second signal comprises a starting voltage signal, and the starting voltage signal is output to a scanning line through the gate driver; the step of controlling a gate driver to output a drive signal according to the first signal and the second signal comprises: controlling a gate driver to output a drive signal according to the first signal and the starting voltage signal; wherein the step of controlling a gate driver to output a drive signal according to the first signal and the starting voltage signal comprises: outputting a power starting signal according to the starting voltage signal; and controlling a gate driver to output a drive signal according to the first signal and the power starting signal; wherein the voltage of the power starting signal is lower than that of the starting voltage signal. 2. The display device driving method according to claim 1 , wherein the step of outputting a power starting signal according to the starting voltage signal comprises: outputting a power starting signal when the voltage of the starting voltage signal reaches 30 V. 3. The display device driving method according to claim 2 , wherein the step of outputting a power starting signal according to the starting voltage signal comprises: bucking the starting voltage signal by a buck circuit and then output the power starting signal.
