Embodiment Construction

[0062] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0063] figure 1 is a flow chart of a screen display method shown according to an exemplary embodiment, such as figure 1 As shown, the screen display method is used in the terminal and includes the following steps.

[0064] In step S11, a grayscale transformation is performed on the first object to be displayed to generate a second object to be displayed.

[0065] In step S12, accord...

Abstract

The invention relates to a screen display method and device. The method comprises steps that gray transformation for a first to-be-displayed object is carried out to generate a second to-be-displayed object; according to a pixel value of the second to-be-displayed object, a driving voltage is inputted to a main data line of a display unit; the driving voltage is sequentally inputted to multiple sub data lines connected with the main data line through the main data line so as to make pixel points corresponding to the multiple sub data lines express the pixel value; the main data line is connected with the multiple sub data lines through a multi-path conversion unit. The method is advantaged in that frequent switching of the driving voltage inputted to the main data line can be avoided, and a purpose of reducing power consumption is realized.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, and in particular to a screen display method and device. Background technique [0002] In the related art, for the display screen, in order to reduce the data line (source line) connected to the display driver or the display processor, the source line of many display screens is implemented through RGB MUX (Multiple User Experiment; multiplexer) Switching, so that the three source lines originally required by RGB are reduced through the RGB MUX circuit. Taking 1:3MUX (three-way switch) as an example, the three source lines connected to the display driver or display processor become one source Wire. [0003] Although the number of source lines can be reduced through the RGB MUX, when displaying images through the display screen, due to the different values ​​of RGB, the level of the input end of the RGB MUX needs to be switched frequently, resulting in increased power consumption of t...
