Abstract: Provided are a color temperature adjustment device and a method for adjusting a color temperature of a liquid crystal panel. A sensor senses the color temperature of the liquid crystal panel. A controller generates a control signal in response to a difference between the sensed color temperature and a predetermined value being greater than a threshold. A backlight circuit is operable to adjust a driving current that drives a backlight unit of the liquid crystal panel in response to the control signal. When the difference is positive, the control signal reduces the driving current; and when the difference is negative, the control signal enhances the driving current.

Abstract: The present disclosure discloses a liquid crystal display driving device, including a time sequence controller, a data and scan drivers, a liquid display panel and a programmable gamma circuit connected to the data driver. The time sequence controller is respectively connected to the data and scan drivers. The data driver coverts an image data to an analog voltage. The programmable gamma circuit outputs a reference voltage to the data driver and used to assign the reference voltage in real time. The reference voltage corrects the analog voltage so the data driver outputs a gray-level voltage to a liquid crystal unit opened by the scan driver to display an image frame or a black frame. It overcome a problem of overlapping a left-eye and right-eye image frames and at the same time greatly decreases a power consumption of a system. The present disclosure also discloses a liquid crystal display driving method.
