Video display device and light source driving method thereof |
摘要 |
A display device uses a field sequential color scheme. Assume that a panel video writing period defines a period from the start of writing image data into a display panel to the completion of displaying the image on the basis of the image data in a sub-frame. A light source driving circuit generates a driving signal for gradually increasing the luminance of a light source of a color corresponding to a displayed image in the present sub-frame from zero to a predetermined value within the panel video writing period of the present sub-frame and for gradually decreasing the luminance of the light source from the predetermined value to zero within the panel video writing period of the next sub-frame. A light source driver drives the light source to emit light in accordance with the driving signal.
