Embodiment Construction

[0046] figure 1 It is a schematic diagram of a driving circuit 100 of a display according to a first embodiment of the present invention. Examples of the above-mentioned display may include (but are not limited to): a liquid crystal display module (Liquid Crystal Display Module, LCM). This is for illustrative purposes only and is not a limitation of the present invention. According to some variations of this embodiment, as long as the implementation of the present invention is not hindered, the above-mentioned display may be a display module not implemented with liquid crystal display technology. To facilitate understanding, figure 1 It also shows the equivalent capacitance of a part of the display unit in the display module 50 (such as the above-mentioned liquid crystal display module) driven by the driving circuit 100, such as the load capacitance C LOAD (n1), C LOAD (n2), C LOAD (n3)..., where the load capacitance C LOAD (n1), C LOAD (n2), C LOAD (n3)... can be regarde...

Abstract

The invention discloses a display driving method and a relevant driving circuit. The display driving method comprises steps of checking the relationship between two voltage levels respectively represented by two continuous digital codes received by a special digital code input end and a first predetermined threshold value, or preferably, checking the relationship between at least one voltage level represented by at least one digital code in the two digital codes and a first predetermined area, so as to determine whether pre-charging is carried out on a special display unit group corresponding to the special digital code input end in a plurality of groups of display units, and temporarily conducting a pre-charging voltage generator to the special display unit group when pre-charging is determined to be carried out on the special display unit group so as to carry out pre-charging on the special display unit group. Thus, the method aims at control of any rising edge or any falling edge of driving signals in any situation so as to enhance the overall efficiency of the display.

Description

Technical field [0001] The present invention relates to a driver for a liquid crystal display module (Liquid Crystal Display Module, LCM), and particularly refers to a display driving method and related driving circuits. Background technique [0002] When the amplifier array in the traditional drive circuit drives a load with capacitive characteristics, in order to charge the equivalent capacitance of the load to the required voltage level, the traditional drive circuit needs to provide sufficient charge, which often causes unnecessary Power consumption. In response to this type of problem, some charge reuse methods have been proposed in related technologies. However, these charge utilization methods often have some side effects, such as the problem of excessive control phases or slow response speed. Therefore, a novel driving method is needed to improve the performance of the driving circuit while improving the aforementioned side effects. Summary of the invention [0003] An ...
