Abstract

The invention discloses a method and device for sharing electric charge. The method comprises the steps that signals capable of carrying out electric charge sharing in a display screen are acquired; whether the change amplitude of the signals capable of carrying out electric charge sharing exceeds the threshold value or not is judged; the signals with the change amplitude exceeding the threshold value are subjected to electric charge sharing. The technical problem that a driving chip of a display screen in the prior art is large in overall power consumption is solved, the power consumption of the chip is reduced, and the work temperature of the chip is reduced.

Description

technical field [0001] The present invention relates to the display field, in particular, to a charge sharing method and device. Background technique [0002] Charge sharing is mainly used in the driver chip of a display screen (such as a liquid crystal display screen), in order to reduce the power consumption of the display screen for charging and discharging. [0003] There are two methods for the charge sharing technology in the prior art. The first method is to short-circuit all the output signals of the signal source, regardless of the signal polarity of the output signal. It is more power-saving when the element (i.e. image unit, also known as pixel) is used for line inversion, but as the LCD panel becomes larger and larger, the resolution is getting higher and higher. In this case, if all signal sources are still output Shorting together will inevitably lead to waste of power consumption; the second way is to adopt the technology of sharing the charge by separating t...
