Abstract

The invention discloses a backlight driving method and device, and a display device; the backlight driving method comprises the following steps: receiving the Nth frame backlight data corresponding tothe Nth frame image data and sent by a serial peripheral interface, wherein N is a positive integer; controlling a corresponding area in the backlight module to illuminate at the corresponding luminance value according to the Nth frame backlight data after the Nth frame liquid crystal deflection is finished. The method and device can solve the technical problems that an existing backlight drivingmethod is easy to cause image streaking and vertigo.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight driving method and device, and a display device. Background technique [0002] As users have higher and higher requirements for image quality, devices such as computers and televisions begin to use multi-zone backlights to display images. Specifically, the Local Dimming (regional backlight) technology often uses a backlight composed of hundreds of LEDs (Light Emitting Diodes, light emitting diodes) to replace the CCFL (Cold Cathode Fluorescent Lamp, cold cathode fluorescent lamp) backlight. According to the brightness of the image, the LED corresponding to the bright part of the displayed image can be adjusted to the maximum brightness, while at the same time, the LED corresponding to the dark part of the displayed image can be correspondingly reduced or even turned off to achieve the best contrast. [0003] At present, the Local Dimming technology is directly appli...
