Abstract

The invention relates to a backlight scanning type display method and a backlight scanning type display system. The display method comprises the steps: grouping at least one part of backlight devicesof a display panel, so as to generate a plurality of backlight device sets; selecting one backlight device from each backlight device set; and turning on the plurality of selected backlight devices insequence, wherein the starting time of the plurality of backlight devices in each backlight device set is not overlapped.

Description

technical field [0001] The present invention discloses a backlight scanning type display method and a backlight scanning type display system, especially a backlight scanning type display method and a backlight that group backlight devices to optimize the turn-on sequence, thereby reducing motion blur effects and improving display brightness Scanning display system. Background technique [0002] Liquid Crystal Display (LCD) and Organic Light Emitting Diode (OLED) display devices have been widely used in multimedia players and mobile phones due to their advantages of light and thin appearance, power saving and no radiation. , personal digital assistants, computer monitors, or flat-screen televisions. [0003] Traditional displays use pulse width modulation signals to drive the backlight when displaying images. And continuously turn on the backlight (called Hold Type Display), so users tend to feel that the picture is unstable and reduce the visual quality when watching the p...
