Abstract
Provided is a driving method for a display device. The driving method includes: obtaining, by the driving chip, a theoretical brightness value of the light-emitting diode in each of the plurality of light-exiting sub-areas based on an image to be displayed on the display panel; obtaining an actual brightness look-up table, searching the actual brightness look-up table for an actual brightness value closest to the theoretical brightness value, and setting the actual brightness value closest to the theoretical brightness value as a first brightness value; and generating a first pulse signal based on the first brightness value and outputting the first pulse signal to the switch in each of the plurality of light-exiting sub-areas, in such a manner that the switch controls, under driving of the first pulse signal, the light-emitting diode to emit light under an action of a first power supply signal and a second power supply signal.
