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.

The display driver includes a data receiver, a bit-width memory, an image processing module, an image data latch, a digital-to-analog (D/A) conversion module, a gamma correction module, a voltage module, a pulse width modulation module, and an image analog data output module. The display driver further includes a control module activated by the processor to detect whether the bit-width memory is turned on. If the bit-width memory is on, the control module turns off the image processing and gamma correction modules. The voltage module provides grey-level voltages for the D/A conversion module according to and corresponding to the image data delivered from the bit-width memory to the image data latch. The image analog data output module is for receiving and outputting the analog signals.

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.
