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: A white balance calibration method includes providing red light, green light, blue light, and white light to a display panel according to first image data; detecting a first temperature of a backlight module when the backlight module provides the red light, green light, blue light, and white light to the display panel; detecting whether luminance of white light of each pixel is lower than maximum luminance of a white light emitting diode (LED) corresponding to the pixel when a first difference between the first temperature and a standard temperature stored in a lookup table is less than a predetermined value; controlling the backlight module to turn on a red LED, a green LED, and a blue LED corresponding to the pixel during turning-on of the white light if the luminance of the white light is lower than the maximum luminance of the white LED corresponding to the pixel.

Abstract: A multi-dimensional touch display device includes a multi-dimensional display device and a touch sensing device. The multi-dimensional display device is used to provide stereoscopic images with different depths. The touch sensing device connected to the multi-dimensional display device has a plurality of sensing surfaces for determining a planar coordinate and a depth of a touch input point.
