Detailed Description
The invention will now be further explained by means of embodiments in conjunction with the accompanying drawings.
The invention is mainly applied to the terminal equipment with the self-luminous screen, controls the display of the self-luminous screen and further achieves the effect of reducing the power consumption; the self-luminous screen, also called as a second generation display screen, such as an AMOLED (Active Matrix/Organic Light Emitting Diode), is different from the currently commonly used backlight screen in a Light Emitting manner, in which pixels in the self-luminous screen emit Light by themselves for display, so that no backlight is required, and power consumption of the self-luminous screen is controlled by adjusting the display effect of the current interface of the self-luminous screen.
In the self-luminous screen, each pixel point uses red, green and blue independent luminescent materials to emit light, the proportion of the three colors is adjusted according to the formation principle of the color spectrum so as to achieve the effect of displaying different colors, when different colors are displayed, the emitted light is different, the power consumption is also different, when black is displayed, the pixel point can not emit any light, the electric quantity is basically not consumed, when white is emitted, the three colors of red, green and blue are emitted together to display white, so the power consumption is maximum and exceeds the power consumption of the traditional TFT (one of Thin Film Transistor, Thin Film field effect Transistor and backlight screen) screen; when a terminal user uses the terminal, the white color is often used as the light emitting color of the background area of the current interface, so that the self-luminous screen consumes a large amount of electric energy, and if the light emitting color of the background area of the current interface can be changed, the purpose of saving electricity can be achieved to a certain extent, but the invention uses the low-power consumption color to replace the light emitting color of different areas of the self-luminous screen in the current mainstream terminal so as to achieve the effect of saving electricity, and in order to facilitate understanding, the 'low-power consumption color' related to the invention is defined:
calculating the power consumption of the pixel in the self-luminous screen, if the power consumption of the pixel is 0.5 unit when the monochromatic light red light (color value, brightness and saturation are maximum) and 0.3 unit when the monochromatic light green light (color value, brightness and saturation are maximum), the power consumption of blue light (color value, brightness, saturation are maximum) is 0.2 unit, then the power consumption of white light (color value, brightness, saturation are maximum) is 1 unit, the power consumption of black light (no light) is 0 unit, the power consumption of dark gray (color value, brightness, saturation are minimum) is 0.1 unit, the power consumption of other colors (such as mixed colors, yellow mixed with red and blue, etc., and the power consumption of color value, brightness, saturation in single color is not maximum) is less than 1 unit; then, in order to highlight the power saving effect of the present invention, the low power consumption color of the present invention refers to all the light emitting colors with the power consumption less than 1 unit, that is, all the colors except the white light, preferably, the low power consumption color of the present invention may only include all the colors with the power consumption less than 0.5 unit when the pixel emits light, wherein, black, gray and monochrome are the best, because black is most power-saving and the monochromatic light display effect is good, of course, in practical application, the low power consumption color, such as yellow, purple, etc., may also be selected according to the preference of the end user;
on the basis of the above, the "non-black low power consumption color" in the present invention refers to all the "low power consumption colors" except black.

The invention will now be further explained by way of specific examples; fig. 3 is a schematic diagram of a terminal display control method according to a third embodiment of the present invention, and fig. 4a to 4c are schematic diagrams of display interfaces corresponding to the terminal display control method according to the third embodiment of the present invention; as can be seen from fig. 3, in this application example, the terminal display control method provided by the present invention includes the following steps:
s301: acquiring the running state of a terminal;
since the control of the self-luminous screen of the terminal has not been started at this time, it is assumed that the time is T0, and at this time, the display interface of the self-luminous screen of the terminal is schematically shown in fig. 4 a; in fig. 4a, the current interface includes a text region (e.g., the text regions such as the language box region and content in the dialog portion in fig. 4a, the user name and phone number of the head-up, and the "send" at the bottom end all belong to the text region, and the "text region" in the following is the same and is not described again), a picture region (e.g., the regions displayed in the picture form such as the user head portrait of the head-up portion in fig. 4a, the video player window in the dialog portion and the like in the dialog portion all belong to the picture region, and the "picture region" in the following is the same and is not described again) and a background region (e.g., the regions not displayed with content such as the blank portion in the dialog portion in fig. 4a all belong to the background region, and the "background region, moreover, the background area emits white light, the characters in the character area emit black light, and the pictures in the picture area emit mixed light;
s302: the detection module detects and judges whether the terminal meets a power saving condition; if yes, executing step S303, and if not, returning to step S301;
in this embodiment, the power saving condition is set to be that the remaining power of the terminal is less than a preset value; detecting whether the terminal meets the power saving condition or not: detecting the residual electric quantity of the terminal, and judging whether the residual electric quantity is smaller than a preset value; for convenience of explanation, assuming that the remaining power a of the terminal happens to be smaller than the preset value Th (which may be a specific power value or a percentage) at time T1, the schematic diagram of the display interface of the self-luminous screen of the terminal from time T0 to time T1 is shown in fig. 4 a;
the terminal executes step S303 at time T1;
s303: the control module selects a processing mode of displaying the current interface in a low-power-consumption color according to the terminal configuration;
for convenience of explanation, in the present embodiment, the current interface is divided into 3 major categories: background area, character area and picture area, and generally, the background area has a larger proportion, the character area is the second order, and the picture area is the smallest; aiming at the 3 large-class areas, whether each area carries out low-power-consumption color display processing or not can be set respectively, and the low-power-consumption colors in each area can also be set respectively, so that a terminal user can select according to own preference only by achieving the power-saving effect;
for the low-power consumption color display processing of the current interface, there are 7 types of processing modes: processing only background regions, processing only text regions, processing only picture regions, processing only background and text regions, processing only background and picture regions, processing only text and picture regions, and processing background, text and picture regions simultaneously; the display effect of the current interface of these 7 types of processing manners can refer to the following description of manners 1 and 2, and will not be described herein again.
S304: the control module controls the self-luminous screen to display the current interface in a low-power consumption color according to the selected processing mode;
two ways and the corresponding display effects are given below by way of example:
mode 1, performing black display processing on a background region, performing monochrome display processing on a character region, and also performing monochrome display processing on a picture region, where a display schematic diagram of a processed current interface is shown in fig. 4 b: the background area is displayed to be black, namely, the pixel points in the area do not emit light, the character area is displayed to be gray, namely, the pixel points in the area emit gray light with the same color parameters, and the picture area is displayed to be gray (the brightness of light emitted among the pixel points is different), namely, the pixel points in the area emit gray light with different color parameters; at this time, the following processing manner may be adopted for the picture of the picture region: detecting color difference values, brightness values and saturation values of all pixel points in the picture area, taking the pixel points with the similar color difference values, brightness values and saturation values as a subarea, and arranging edge lines between the subareas with the larger color difference values, brightness values and saturation values as contour lines;
mode 2, performing black display processing on the background area, performing monochrome display processing on the text area, and not performing monochrome display processing on the picture area, where a display schematic diagram of the processed current interface is shown in fig. 4 c: the background area is displayed as black, that is, the pixel points in the area do not emit light, the text area is displayed as gray, that is, the pixel points in the area emit gray light with the same color parameters, and the picture area in the picture area is displayed in a consistent manner in the picture area shown in fig. 4 a.
In summary, the implementation of the present invention has at least the following advantages:
the invention detects whether the terminal meets the power saving condition, and when the terminal meets the power saving condition, the current interface of the terminal is displayed by controlling the self-luminous screen of the terminal in a low-power consumption color, because the invention does not require the user to select to close the terminal application, the invention ensures the use experience of the terminal user while reducing the power consumption of the terminal, and solves the problem of poor user experience caused by prolonging the endurance time of the terminal by closing the terminal application in the prior art;
furthermore, the power saving condition is set to be that the residual electric quantity of the terminal is smaller than the preset value, if the electric quantity is sufficient, the residual electric quantity is not processed, and the residual electric quantity is displayed in a low-power-consumption color only when the electric quantity of the terminal is insufficient, so that the endurance time of the terminal is prolonged, and the use experience of a user is enhanced.
