Abstract

The invention provides a display device and a backlight drive method thereof. The display device comprises a backlight module and a display panel. The backlight module comprises at least one light emitting diode unit containing red phosphorescent material. The light emitting diode unit is switched on at least twice in a frame period and maintains on for a first switch-on duration and a second switch-on duration separately, and the second switch-on duration is less than the first switch-on duration. The display panel corresponds to the backlight module.

Description

technical field [0001] The present invention relates to a display device, and in particular to a display device with a light-emitting diode (Light-Emitting Diode, LED) backlight source and a driving method for the backlight source thereof. Background technique [0002] Light-emitting diodes have the advantages of long service life, small size, unbreakable, low heat output, and low energy consumption. They have gradually replaced traditional cathode ray displays and become the mainstream of displays. [0003] In recent years, the development trend of displays is mainly moving towards the direction of multi-color and high brightness. Generally speaking, in order to obtain a full-color display image, the backlight module usually assembles red, green and blue three-color visible light LED dies together to mix visible light of various wavelengths to obtain a white light source. However, this design needs to use a relatively large number of LED packaging structures, and the cost ...
