[0022] Now, the present invention will be further explained and explained by means of specific embodiments in combination with the drawings.
[0023] The present invention is mainly applied to terminal devices with self-luminous screens to control the display of the self-luminous screens, thereby achieving the effect of reducing power consumption; self-luminous screens are also called second-generation display screens, such as AMOLED (Active Matrix/Organic) Light Emitting Diode (Active Matrix Organic Light Emitting Diode Panel), which is different from the currently commonly used backlight screen, is displayed by the pixels in the self-luminous screen, so it does not need backlight, and then It can control the power consumption of the self-luminous screen by adjusting the display effect of the current interface of the self-luminous screen.
[0024] In a self-luminous screen, each pixel emits light with independent luminescent materials of red, green, and blue, and adjusts the ratio of these three colors according to the formation principle of the color spectrum to achieve the effect of displaying different colors. When displaying different colors, The light emitted is different, and the power consumption is also different. When displaying black, the pixel does not emit any light, which basically does not consume power. When it is white, the red, green, and blue colors will be displayed in white. Therefore, the power consumption is the largest, and exceeds the power consumption of the traditional TFT (Thin Film Transistor, a kind of backlit screen) screen; while the end user often uses white as the background area of the current interface to emit light The color causes the self-luminous screen to consume a lot of power. If the luminous color of the background area of the current interface can be changed, the purpose of power saving can be achieved to a certain extent. The present invention uses low-power color to replace the current mainstream The light-emitting colors of different areas of the self-luminous screen in the terminal achieve the power saving effect. For ease of understanding, the "low-power color" involved in the present invention is now defined:
[0025] Calculate according to the power consumed by the pixel point in the self-luminous screen. If it is assumed that the pixel point monochrome light red light (color value, brightness, saturation is the maximum), the power consumption is 0.5 unit, green light (color color) When the value, brightness and saturation are the maximum), the power consumption is 0.3 unit, and the power consumption when the blue light (color value, brightness, saturation is the maximum) is 0.2 unit, then white light (color value, brightness , When the saturation is maximum), the power consumption is 1 unit, when it is black (no light), the power consumption is 0 unit, and the power consumption is dark gray (color value, brightness, saturation is the minimum) The power consumption of other colors (such as mixed colors, such as red and blue mixed into yellow, etc., the color value, brightness, and saturation of the color in a single color is not the maximum) is also less than 1 unit; then, for To highlight the power-saving effect of the present invention, the low-power color referred to in the present invention refers to all light-emitting colors whose power consumption is less than 1 unit, that is, all colors other than white light are emitted. Preferably, it can only include the light-emitting pixels. The power consumption is less than 0.5 unit of all colors. Among them, black, gray and monochrome are the best, because black is the most power-saving and has a good monochrome light display effect. Of course, in practical applications, it can also be based on the preferences of end users. Choose low-power colors, such as yellow, purple, etc.;
[0026] On this basis, the "non-black low-power color" referred to in the present invention refers to all "low-power colors" except black.
[0027] figure 1 Is a schematic diagram of a terminal display control method provided by the first embodiment of the present invention, which is composed of figure 1 It can be seen that, in this embodiment, the terminal display control method provided by the present invention includes the following steps:
[0028] S101: Obtain the running status of the terminal;
[0029] The method of acquiring the operating status of the terminal may be real-time acquisition or periodic acquisition. Since the terminal also detects its own operating status during normal operation, this step does not cause too much additional power consumption;
[0030] S102: Detect and determine whether the terminal meets the power saving condition; if it is satisfied, execute step S103, if not, then return to step S101;
[0031] S103: Control the self-luminous screen to display the current interface in a color with low power consumption.
[0032] Better, figure 1 The low-power color in the illustrated embodiment includes black; the step of controlling the self-luminous screen to display the current interface in low-power color includes: controlling the self-luminous screen to display the background area in the current interface in black, that is, the background in the current interface The area is displayed in black.
[0033] Better, in figure 1 In the illustrated embodiment, if the current interface includes text, the step of controlling the self-luminous screen to display the current interface in a low-power color color further includes: controlling the self-luminous screen to use a non-black low-power color (such as dark gray or low brightness) Monochrome) displays the text in the current interface, that is, the text in the current interface is displayed in a non-black color with low power consumption.

[0035] Better, figure 1 The color parameters in the illustrated embodiment include at least one of brightness, saturation, and color value. Of course, the color parameter may also include other parameters that can distinguish color differences.
[0036] Better, figure 1 The power saving conditions in the illustrated embodiment include that the remaining power of the terminal is less than a preset value; the specific steps of detecting whether the terminal meets the power saving conditions include: detecting the remaining power of the terminal and determining whether the remaining power is less than the preset value.
[0037] In other embodiments of the present invention, the power saving condition may also be that the terminal is always in the power saving mode, then, correspondingly, figure 1 Step S101 in the illustrated embodiment can be omitted, because the operation of the terminal at this time has no effect on whether the terminal needs to perform power saving processing; correspondingly, in other embodiments of the present invention, the power saving conditions are also acceptable It is whether the power consumption of the terminal in a unit time is greater than the threshold. For example, the terminal consumes 100 units of power per hour during normal use. If in a certain period of time, it is detected that the terminal consumes 500 units of power per hour, which is greater than 200 units/hour (It is a threshold and can be set by yourself), then at this time, the control terminal will be in power saving mode, and the current interface will be displayed in low-power color.

[0047] Better, in figure 2 In the illustrated embodiment, the control module 23 controls the display interface of the self-luminous screen by controlling the light-emitting mode of each pixel in the self-luminous screen; the control mode can be such as: a certain pixel should emit white light, then The pixel should trigger the red, green, and blue independent light-emitting materials to emit light at the same time. At this time, the control module 23 in the present invention sends a stop signal to the pixel to prevent the pixel from emitting light at this moment, then, The pixel point appears as black light. Correspondingly, a certain pixel point should emit red light, then the pixel point should trigger the red light-emitting material to emit light. At this time, the control module 23 of the present invention sends a modification to the pixel point. Signal to prevent the pixel from emitting red light and changing to emit blue light at that moment, then the pixel will appear as blue light.
[0048] The present invention will be further explained and illustrated in combination with specific examples; image 3 Is a schematic diagram of a terminal display control method provided by the third embodiment of the present invention, Figure 4a to Figure 4c It is a schematic diagram of a display interface corresponding to the terminal display control method provided by the third embodiment of the present invention; image 3 It can be seen that in this application example, the terminal display control method provided by the present invention includes the following steps:
[0049] S301: Obtain the running status of the terminal;
[0050] Since the control of the self-luminous screen of the terminal has not yet begun, it is assumed that this time is T0. At this time, the schematic diagram of the display interface of the self-luminous screen of the terminal is as follows: Figure 4a Shown in Figure 4a , The current interface includes text areas (such as Figure 4a The language box area and content in the middle dialogue part, the user name and phone number on the header, the "send" at the bottom and other words area belong to the text area, the "text area" below is the same as this, and will not be repeated), pictures Area (e.g. Figure 4a The user avatar in the header part, the video player window in the conversation part, and other areas displayed in the form of pictures belong to the picture area. The "picture area" below is the same as this and will not be repeated) and the background area (such as Figure 4a The blank part of the dialogue part in the middle part of the dialogue part and other areas with no content displayed belong to the background area. The "background area" below is the same as this and will not be repeated), and the background area is white, the text in the text area is black, The picture in the picture area emits mixed light;
[0051] S302: The detection module detects and judges whether the terminal meets the power saving condition; if it is satisfied, execute step S303, if not, then return to step S301;
[0052] In this embodiment, the power saving condition is set to be that the remaining power of the terminal is less than a preset value; the specific steps for detecting whether the terminal meets the power saving condition include: detecting the remaining power of the terminal and determining whether the remaining power is less than the preset value; for convenience Note, assuming that at time T1, the remaining power A of the terminal is coincidentally less than the preset value Th (which can be a specific power value or a percentage), then, from time T0 to time T1, the terminal self-luminous screen displays The schematic diagram of the interface is like Figure 4a Shown
[0053] The terminal executes step S303 at time T1;
[0054] S303: The control module selects a low-power color display processing mode of the current interface according to the terminal configuration;
[0055] For ease of description, in this embodiment, the current interface is divided into three types of areas: background area, text area, and picture area. Generally, the background area occupies a larger proportion, the text area is second, and the picture area is the smallest. ; For these three types of areas, you can set whether to perform low-power color display processing in each area separately, and the low-power color in each area can also be set separately, and the end user can choose according to their own preferences. Just achieve the power saving effect;
[0056] For the low-power color display processing of the current interface, there are 7 types of processing methods: processing only the background area, processing only the text area, processing only the image area, processing only the background and text area, processing only the background and image area, processing only Text and picture area, background, text and picture area are processed at the same time; the display effect of the current interface of these 7 types of processing methods can refer to the description of methods 1 and 2 below, which will not be repeated here.
[0057] S304: The control module controls the self-luminous screen to display the current interface in low-power color according to the selected processing mode;
[0058] The following exemplarily gives two methods and their corresponding display effects:
[0059] Method 1. Perform black display processing on the background area, monochrome display processing on the text area, and monochrome display processing on the picture area. The displayed schematic diagram of the current interface after processing is as follows Figure 4b As shown: the background area is displayed as black, that is, the pixels in the area do not emit light, and the text area is displayed as gray, that is, the pixels in the area emit gray light with the same color parameters, and the image area is displayed as gray (one of each pixel). The brightness of the light is not the same), that is, the pixels in the area emit gray light with different color parameters; at this time, the following processing methods can be used for the pictures in the picture area: detect the color difference of each pixel in the picture area , Brightness value and saturation value, the pixels with similar color difference, brightness value and saturation value are regarded as a sub-region, and edge lines are set between the sub-regions with large difference in color difference, brightness value and saturation value As a contour line
[0060] Method 2. Perform black display processing on the background area, monochrome display processing on the text area, and no monochrome display processing on the picture area. The displayed schematic diagram of the current interface after processing is as follows Figure 4c Shown: the background area is displayed as black, that is, the pixels in the area do not emit light, and the text area is displayed as gray, that is, the pixels in the area emit gray light with the same color parameters, and the image area is displayed Figure 4a The display in the picture area is the same.
[0061] In summary, through the implementation of the present invention, there are at least the following beneficial effects:
[0062] The present invention detects whether the terminal meets the power-saving conditions, and when it is detected that the terminal meets the power-saving conditions, the self-luminous screen of the control terminal displays the current interface of the terminal with low power consumption colors, because the present invention does not require the user to choose to turn off the terminal Therefore, while reducing the power consumption of the terminal, the present invention ensures the user experience of the terminal user, and solves the problem of poor user experience caused by the prior art by closing the terminal application to extend the battery life of the terminal;
[0063] Further, by setting the power-saving condition as the remaining power of the terminal is less than the preset value, if the power is sufficient, it will not be processed. Only when the power of the terminal is insufficient, it will be displayed in low-power color, which will extend the battery life of the terminal while also enhancing Improve the user experience.
[0064] The above are only specific embodiments of the present invention, and do not limit the present invention in any form. Any simple modification, equivalent change, combination or modification of the above embodiments based on the technical essence of the present invention still belongs to the present invention.
