Abstract: An anti-flicker and motion-blur improvement method includes selecting one of display modes, obtaining a vertical synchronization signal and a data clock signal, and setting waveforms of a backlight driving signal in a vertical blanking interval and a data scan interval according to the display mode to make a motion blur effect correspond to the display mode. A voltage regulation signal is generated according to the display mode. A duty cycle of the voltage regulation signal is set as a first duty cycle in a dynamic image display mode. The duty cycle of the voltage regulation signal is set as a second duty cycle in a still image display mode. A backlight driving current corresponding to the backlight driving signal is generated via the voltage regulation signal. A current setting port generates a constant current. Accordingly, the present invention can improve the motion blur phenomenon by simplifying the backlight control circuit.

Abstract: The invention provides a backlight device, an operation method, and a display device for reducing motion blur. The display device includes a display panel, a scaler integrated circuit, and a backlight device. The backlight device includes N light zones for providing a backlight to the display panel, wherein N is a positive integer. The backlight device lights each of the N light zones in a time-sharing manner in each of a plurality of scan periods. Each of the scan periods has a time length greater than or equal to a time length of a video active data period of the display panel. A continuous lighting time length of each of the N light zones is less than or equal to a quotient of the time length of the video active data period divided by N.

Abstract: An image display device is provided. The image display device includes a display unit and a backlight module. The display unit is used for displaying pictures in an image frame cycle. The backlight module includes a plurality of light sources of different colors. The image frame cycle is divided into a first interval, a second interval and a third interval in sequence, and the second interval is adjacent to the first interval. The backlight module provides a white light source with a first intensity in the first interval and provides a white light source with a second intensity in the second interval, and the second intensity is smaller than the first intensity. The backlight module is turned off in the third interval.

Abstract: The application discloses an image display device and a control method thereof. The control method for the image display device includes: receiving a first image signal from a host and displaying a frame, a first frame data of the first image signal having a first frequency; determining that the image display device enters a Motion Blur Reduction (MBR) mode and writing a double frequency of a vertical synchronous signal into a storage unit; and informing the host to read the storage unit and alternatively outputting a second frame data and a black-insertion frame data from the host, the second frame data having a second frequency higher than the first frequency.

Abstract: A display method includes selecting a display mode from a plurality of display modes, acquiring a data clock signal having a data period including a pixel active interval and a blank interval, and setting waveforms of a backlight driving signal within the pixel active interval and the blank interval according to the display mode in order to meet a motion blur effect corresponding to the display mode. A power ratio of the backlight driving signal within the blank interval to the backlight driving signal within the pixel active interval determines the motion blur effect. The waveforms of the backlight driving signal within the pixel active interval and the blank interval are different.
