Detailed Description
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, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a screen display method according to an exemplary embodiment, and the screen display method, as shown in fig. 1, is used in a terminal and includes the following steps.
In step S11, the first object to be displayed is subjected to gradation conversion, and a second object to be displayed is generated.
In step S12, a driving voltage is input to the total data lines of the display cells according to the pixel value of the second object to be displayed.
In step S13, the driving voltages are sequentially input to a plurality of sub data lines connected to the total data line through the total data line so that pixel points corresponding to the plurality of sub data lines can represent the pixel values.
The terminal in the present disclosure may be a smartphone, a tablet computer, a notebook computer, an e-book reader, etc. The Display screen of the terminal may be an LCD (Liquid Crystal Display) or an OLED (Organic Light-Emitting Diode) Display screen. A MUX switch is used on a display screen of the terminal, a total data line is connected with a display processor or a single display driver DDIC of the terminal, and the total data line is connected with a plurality of sub data lines through a multiplexing unit, namely the MUX switch.
Taking RGB MUX as an example, as shown in fig. 2, which is a schematic diagram of RGB MUX switches, the total data may be connected to the sub data line corresponding to the R channel, the sub data line corresponding to the B channel, and the sub data line corresponding to the G channel through RGB MUX. Assuming a resolution of 1920 × 1080 of the display screen, a pixel is usually composed of 3 sub-pixels, each column of pixels on the display screen includes three sub-data lines, and if each row has 1080 pixels, the display screen includes 1080 total data lines and 1080 × 3 sub-data lines. During the scanning time of one row, the circuit including the RGB MUX switch can input the driving voltage to different sub data lines by time division multiplexing.
In the present disclosure, the color mode of the object to be displayed may be an RGB color mode, a CMYK color mode, a Lab color mode, or the like, and in the present disclosure, the screen display method is described with the color mode of the object to be displayed being the RGB color mode.
First, in step S11, the second object to be displayed may be obtained through the following three implementations, but is not limited to the following three implementations. In the following three implementations, R0，G0，B0Is the pixel value on the first object to be displayed, R, G, B is the pixel value on the second object to be displayed.
The first implementation mode comprises the following steps: maximum value method. Let R ═ G ═ B ═ max (R ═ G ═ B-0，G0，B0) That is, let R be0，G0，B0The largest value in (a) is the new R, G, B value.
The second implementation mode comprises the following steps: average value method. Make R, G, B equal to R0，G0，B0I.e. R ═ G ═ B ═ R (R)0+G0+B0)/3。
The third implementation mode comprises the following steps: weighted average method. Giving R according to importance or other criteria0、G0、B0Giving different weights and weighted averaging R, G, B values, i.e. R, G, B (WrR)0+WgG0+WbB0) (ii)/3, wherein Wr, Wg and Wb are each R0、G0、B0The weight of (2).
In practical applications, since the human eye has high sensitivity to green, lower sensitivity to red than to green, and lowest sensitivity to blue, Wg > Wr > Wb may be taken, for example: let Wr be 0.30, Wg be 0.59, and Wb be 0.11.
Then, in step S12, a driving voltage is input to the total data lines of the display cells according to the pixel value of the second object to be displayed. For an RGB image, the pixel values of the pixels include the value of the R channel, the value of the G channel, and the value of the B channel. Taking the value of the R channel as an example, the value of R is [0, 255], where each step corresponds to a voltage value. For example, assuming that the global data line is connected to the driving display unit, if R, G, B, 216 corresponds to a voltage of 4.7V, the driving voltage input to the global data line by the driving display unit is 4.7V.
In step S13, the driving voltages are sequentially input to a plurality of sub data lines connected to the total data line through the total data line so that pixel points corresponding to the plurality of sub data lines can represent the pixel values. After the driving voltage is input to the sub data lines, the liquid crystal molecules rotate, so that the pixel points can express the pixel values, and multi-gray-scale display is realized.
In the disclosure, the gray scale conversion is performed on the color image, so that R ═ G ═ B of the converted gray scale image is achieved, and since R ═ G ═ B, the voltages on the three sub-data lines are the same or the difference is small, thereby reducing the switching times and the switching amplitude of the voltage of the total data line, and reducing the power consumption of the terminal.
In the present disclosure, the brightness of the first color channel in the RGB color mode may also be reduced, so that the brightness of the display screen is darkened. For example: the first color channel can be a B channel, and the effect similar to reading of old newspapers can be created by reducing the brightness of the B channel, so that the eyes of a user are protected, and the user experience is improved.
In one possible implementation, as shown in FIG. 3, reducing the brightness of the first color channel includes the following steps.
In step S1211, a second driving voltage corresponding to each gray scale of a first color channel of a plurality of color channels is obtained according to a preset transmittance, a first driving voltage and a preset gamma value, wherein the first driving voltage is an original driving voltage of the display unit, the plurality of color channels correspond to the pixel values, and the plurality of color channels correspond to the plurality of sub data lines one to one.
For example, assuming that the required brightness is 85% of the original brightness of the display screen, i.e., the predetermined transmittance is 85%, the driving voltage corresponding to the value 216 (i.e., 255 × 85%) of the first color channel may be selected as the driving voltage of the gray scale 255. For example: the original driving voltage corresponding to the original gray scale 255 is 5v, the voltage of the measured 216 is 4.7v, and the corresponding new driving voltage is 4.7v when the gray scale is 255, so that the brightness of 255 is 85% of the original brightness, thereby reducing the brightness of the first color channel and further reducing the overall brightness.
After the driving voltage corresponding to the brightness level 255 is determined, the luminance data 255brightness when the driving voltage is 4.7V can be obtained by measurement, then the luminance data of each gray level can be obtained according to the formula (N/255) ^ gamma-nbright/255 brightness, and the second driving voltage corresponding to each gray level can be obtained according to the luminance data of each gray level. Wherein gamma is a known predetermined gamma value, N is [0, 255], and Nbgightness is the luminance data when the gray scale is N.
In step S1212, the second driving voltage corresponding to the value of the first color channel in the pixel values is input to the total data line according to the pixel values. Since the second driving voltage corresponding to each gray scale is obtained, the value of the first color channel can be determined according to the value of the first color channel in the pixel values to determine the second driving voltage, for example: if the value of the first color channel is 130, the driving voltage is a second driving voltage corresponding to the gray scale 130.
Then, in step S13, the second driving voltage is input to a first sub data line corresponding to the first color channel among the plurality of sub data lines through the total data line. For example: and if the first color channel is a channel B, inputting the second driving voltage to the sub data line corresponding to the channel B through the total data line.
In another possible implementation, as shown in fig. 4, reducing the brightness of the first color channel comprises the following steps.
In step S1221, a value of a first color channel in the pixel values is reduced to a preset value.
In the present disclosure, the correspondence between the value of the first color channel and the preset value may be set in advance. For example, assuming that the required brightness is 85% of the original brightness of the display screen, that is, the preset transmittance is 85%, when the value of the first color channel is 255, the value 216 (that is, 255 × 85%) of the first color channel may be selected as the preset value; another example is: when the value of the first color channel is 100, the value of the first color channel is 85 (i.e., 100 × 85%) as the preset value. Then in step 1221, the preset value can be determined directly from the above correspondence.
In step S1222, the driving voltage corresponding to the preset value is input to the total data line based on the preset value. Then, in step S13, the driving voltage is input to a first sub data line corresponding to the first color channel among a plurality of sub data lines through the total data line. For example: the first color channel is a channel B, the value of the channel B is 255, the corresponding preset value is 216, and the driving voltage corresponding to 216 is 4.7V, and then the driving voltage of 4.7V is input to the sub data line corresponding to the channel B through the total data line.
According to the method and the device, after the gray level conversion is carried out on the color image, the brightness of one color channel in the gray level image is reduced, so that the power consumption of a terminal can be reduced, the brightness of a display screen can be reduced, the eyes of a user are protected, and the user experience degree is improved.
