Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

Fig. 1 is a flowchart of a screen display method according to an exemplary embodiment. As shown in Fig. 1 , the screen display method used in a terminal includes the following steps.

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

In step S12, a driving voltage is input to the total data line of the display unit according to the pixel value of the second object to be displayed.

In step S13, the driving voltage is sequentially input to a plurality of sub data lines connected to the main data line through the main data line, so that the pixel points corresponding to the plurality of sub data lines can represent the pixel value.

The terminal in the present disclosure may be a smart phone, a tablet computer, a notebook computer, an e-book reader, and the like. The display screen of the terminal may be an LCD (Liquid Crystal Display; liquid crystal display) or an OLED (Organic Light-Emitting Diode; organic light emitting diode) display screen. A MUX switch is used on the display screen of the terminal, the main data line is connected to the display processor of the terminal or a single display driver DDIC, and the main data line is connected to a plurality of sub-data lines through a multiplexing unit, that is, the MUX switch.

Taking RGB MUX as an example, as shown in Figure 2, it is a schematic diagram of the RGB MUX switch. The total data can be divided into the sub data lines corresponding to the R channel, the sub data lines corresponding to the B channel, and the sub data lines corresponding to the G channel through the RGB MUX. connect. Assuming that the resolution of the display screen is 1920*1080, a pixel is usually composed of 3 sub-pixels, then each column of pixels on the display screen includes three sub-data lines, if each row has 1080 pixels, the display screen includes 1080 total data lines line and 1080*3 sub data lines. During the scanning time of one line, the circuit including the RGB MUX switches can input driving voltages to different sub-data lines through time-division multiplexing.

In the present disclosure, the color mode of the object to be displayed may be RGB color mode, CMYK color mode, Lab color mode, etc. In the present disclosure, the screen display method is described by taking the color mode of the object to be displayed as the RGB color mode.

First, in step S11, the second to-be-displayed object may be obtained through the following three implementation manners, but is not limited to the following three implementation manners. In the following three implementation manners, R ₀ , G ₀ , and B ₀ are pixel values on the first object to be displayed, and R, G, and B are pixel values on the second object to be displayed.

The first implementation method: the maximum value method. Let R=G=B=max(R ₀ , G ₀ , B ₀ ), that is, let the maximum value of R ₀ , G ₀ , and B ₀ be the new R, G, and B values.

The second implementation method: the average method. Let the values of R, G, and B be equal to the average value of R ₀ , G ₀ , and B ₀ , that is, R=G=B=(R ₀ +G ₀ +B ₀ )/3.

The third implementation method: weighted average method. Give different weights to R ₀ , G ₀ , and B ₀ according to the importance or other indicators, and make the weighted average of the values of R, G, and B, that is, R=G=B=(WrR ₀ +WgG ₀ +WbB ₀ ) /3, where Wr, Wg, and Wb are the weights of R ₀ , G ₀ , and B ₀ respectively.

In practical applications, since the human eye is highly sensitive to green, less sensitive to red than green, and least sensitive to blue, Wg>Wr>Wb can be taken, for example: take Wr=0.30, Wg=0.59, Wb=0.11.

Then, in step S12, a driving voltage is input to the total data line of the display unit according to the pixel value of the second object to be displayed. For RGB images, the pixel value of a pixel includes 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 main data line is connected to the driving display unit, if R=G=B=216, and the voltage corresponding to 216 is 4.7V, the driving voltage input by the driving display unit to the main data line is 4.7V.

In step S13, the driving voltage is sequentially input to a plurality of sub data lines connected to the main data line through the main data line, so that the pixel points corresponding to the plurality of sub data lines can represent the pixel value. After the driving voltage is input to the sub-data line, the liquid crystal molecules will rotate, so that the pixel points can represent the pixel value, thereby realizing multi-grayscale display.

In the present disclosure, by performing grayscale conversion on the color image, R=G=B of the converted grayscale image. Since R=G=B, the voltages on the three sub-data lines are the same or the difference is small, thereby reducing the overall The switching times and switching amplitude of the voltage of the data line reduce the power consumption of the terminal.

In the present disclosure, the brightness of the first color channel in the RGB color mode can also be reduced, so that the brightness of the display screen is dimmed. For example, the first color channel can be the B channel. By reducing the brightness of the B channel, an effect similar to reading an old newspaper can be created, thereby protecting the user's eyes and improving the user experience.

In a possible implementation manner, as shown in FIG. 3 , reducing the brightness of the first color channel includes the following steps.

In step S1211, according to the preset transmittance, the first driving voltage and the preset gamma value, a second driving voltage corresponding to each gray level of the first color channel in the plurality of color channels is obtained, wherein the The first driving voltage is the 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, that is, the preset transmittance is 85%, the driving voltage corresponding to the value 216 (ie, 255*85%) of the first color channel can be selected. as the driving voltage of the gray scale 255 . For example: the original driving voltage corresponding to the original grayscale 255 is 5v, and the measured voltage of 216 is 4.7v, then when the grayscale is 255, the corresponding new driving voltage is 4.7v, so that the brightness of 255 will be the original brightness 85%, thereby reducing the brightness of the first color channel, which in turn reduces the overall brightness.

After the driving voltage corresponding to the brightness level of 255 is determined, the brightness data 255brightness when the driving voltage is 4.7V can be obtained by measurement. Then, according to the formula (N/255)^gamma=Nbrightness/255brightness, each gray level can be obtained. The luminance data of each gray scale is further obtained, and the second driving voltage corresponding to each gray scale is obtained according to the luminance data of each gray scale. Among them, gamma is a known preset gamma value, the value of N is [0, 255], and Nbrightness is the brightness data when the gray scale is N.

In step S1212, according to the pixel value, input the second driving voltage corresponding to the value of the first color channel in the pixel value to the total data line. Since the second driving voltage corresponding to each grayscale is obtained, the value of the first color channel can be determined to determine the second driving voltage according to the value of the first color channel in the pixel value. For example, the value of the first color channel is 130 , the driving voltage is the second driving voltage corresponding to the gray scale 130 .

Then, in step S13, the second driving voltage is input to the first sub-data line corresponding to the first color channel among the plurality of sub-data lines through the general data line. For example, if the first color channel is the B channel, the second driving voltage is input to the sub data line corresponding to the B channel through the main data line.

In another possible implementation manner, as shown in FIG. 4 , reducing the brightness of the first color channel includes the following steps.

In step S1221, the value of the first color channel in the pixel values is reduced to a preset value.

In the present disclosure, the corresponding relationship between the value of the first color channel and the preset value may be preset. For example, assuming that the required brightness is 85% of the original brightness of the display screen, that is, the preset transmittance is 85%, then when the value of the first color channel is 255, the value of the first color channel 216 ( That is, 255*85%) as the preset value; another example: when the value of the first color channel is 100, the value of the first color channel can be selected as 85 (ie, 100*85%) as the preset value value. Then, in step 1221, the preset value can be directly determined through the above-mentioned corresponding relationship.

In step S1222, based on the preset value, the driving voltage corresponding to the preset value is input to the bus data line. Then, in step S13, the driving voltage is input to the first sub-data line corresponding to the first color channel among the plurality of sub-data lines through the general data line. For example: the first color channel is channel B, the value of channel B is 255, the corresponding preset value is 216, and the driving voltage corresponding to 216 is 4.7V, then input 4.7V to the sub data line corresponding to channel B through the bus data line drive voltage.

In the present disclosure, by reducing the brightness of one color channel in the grayscale image after performing grayscale conversion on the color image, both the power consumption of the terminal and the brightness of the display screen can be reduced, thereby protecting the user's eyes and improving the User experience.
