Abstract
A display apparatus and a backlight driving method of the same are provided. The display apparatus includes a backlight module and a display panel. The backlight module includes at least one LED unit having a red phosphor. The backlight module turns on the LED unit at least twice within a frame period, and maintains the ON-state of the LED unit for a first ON-state interval and a second ON-state interval. The second ON-state interval is shorter than the first ON-state interval. The display panel is disposed corresponding to the backlight module.
Claims13
A display apparatus, comprising:
- a backlight module comprising at least one LED unit having at least a red phosphor;
- wherein, the LED unit has a first ON-state interval and a second ON-state interval within a frame period, and the second ON-state interval is shorter than the first ON-state interval;
- and
- a display panel disposed corresponding to the backlight module.
