Abstract

A control method is sutiable for a display and is provided with a general mode and a power saving mode. The control method, in the power saving mode, includes the steps of: obtaining a second gray scale data according to a plurality of first gray scale datas, wherein the first gray scale datas are repsectively correpsonding to a plurality of first primary colors, and the second gray scale data is corresponding to a second primary color besides the first primary colors, and generating a plurality of thrid grey scale data according to the first gray scale datas and the second grey scale data, wherein first primary color grey data and second grey scale data are defined in the thrid grey scale data, the first primary color grey data is related to the first primary color and the second primary color grey data is related to the second primary color; and regulating the third grey scale data according to a comparison strengthening function; and finally querying a plurality of driving grey scale datas according to the regualted third grey scale data and driving the display by means of the driving grey scale datas to show an image.

Description

technical field [0001] The present invention relates to a control method, in particular to a control method for controlling grayscale data of multiple primary colors. Background technique [0002] With the advancement of technology, liquid crystal displays have been widely used in various mobile information display devices, such as mobile phones and tablet computers. In such electronic products, battery life has always been one of the most important issues for consumers. In addition to network or GPS positioning, LCD displays account for a very high proportion of power consumption. Now, the specifications of liquid crystal displays continue to pursue wide color gamut, high brightness and ultra-high resolution, so a backlight module with special specifications and a more complex graphics processing unit (GPU) may be required. [0003] However, these specification changes will increase the power consumption of the LCD panel, and shorten the use time of the electronic device ...
