Abstract: The present disclosure relates to a liquid crystal panel and the driving circuit. The liquid crystal panel includes a plurality of source driving circuits and a plurality of sub-pixel rows extending along a row direction. Each of the sub-pixel rows includes a plurality of sub-pixels of different colors and the sub-pixels are arranged periodically along the row direction. Within one scanning frame, polarity of driving voltage of at least one sub-pixel within the arranging period is opposite to that of other sub-pixels. Each of the source driving circuit includes at least two output ends respectively connecting to at least two sub-pixels having the same polarity of driving voltage within the same scanning frame to provide the driving voltage of the same polarity to the at least two sub-pixels. In this way, the power consumption of the source driving circuit may be reduced.

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.
