A display method for reducing motion blur in a video is provided. The display method includes the following steps. Receive a video signal including multiple frames. Display the multiple frames sequentially in multiple frame intervals on a display panel, wherein each frame interval includes a vertical blanking interval and a data scan interval. Provide a backlight enable signal in each frame interval to control turning on and turning off of a backlight unit for the display panel. The backlight enable signal includes a first enable pulse and a blanking enable pulse. The first enable pulse is in the data scan interval. The blanking enable pulse is in the vertical blanking interval. The backlight unit is turned on during the first enable pulse and the blanking enable pulse.

Display method and device for reducing motion blur

A picture adjusting method includes steps of measuring a plurality of first original parameters in a first picture and measuring a plurality of second original parameters in a second picture for a plurality of color patterns; calculating a first gain factor according to the first original parameters and the second original parameters of at least one of the color patterns except a black pattern; subtracting a product of the first original parameters of the black pattern and the first gain factor from the second original parameters of the black pattern to obtain a plurality of first offset values; adding the first offset values to the first original parameters of each color pattern to obtain a plurality of first updated parameters in the first picture; and multiplying the first updated parameters by a second gain factor to obtain a plurality of first adjusted parameters in the first picture.

The first enable pulse is in the data scan interval. The backlight unit is turned on during the first enable pulse.

A displaying system having a function of sensing displaying properties includes a displaying panel, a controlling module, and an optical sensor. The displaying panel has a displaying surface which includes a presentation area and a function area. The function area is at a side of the displaying panel. The function area has a length in pixels longer than that of the presentation area. The controlling module is electrically connected to the displaying panel and the optical sensor and controls the displaying panel to display a presentation image displayed on the displaying area and an image for inspection on the function area. The optical sensor is disposed corresponding to the function area and senses the image for inspection to generate an inspection signal relative to the image for inspection. Thereby, the controlling module can further adjust displaying parameters of the displaying panel.
