All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
As shown in fig. 1, the method for saving power applied to an OLED screen device includes: step 110 to step 130.
And step 110, responding to the interface call for displaying the target webpage, and monitoring the real-time electric quantity of the equipment.
In some embodiments of the present application, the power saving method applied to the OLED screen device disclosed in the embodiments of the present application may be installed in a browser in the form of a plug-in, or may be called by a target web page in the form of a method or a code library. Then, the power saving method applied to the OLED screen device disclosed in the embodiment of the present application will be executed while the target web page is displayed.
When the power saving method applied to the OLED screen device disclosed by the embodiment of the application is operated, the real-time electric quantity monitoring of the device is started firstly.
In some embodiments of the present application, the real-time electric quantity of the device may be obtained by calling a power management interface provided by an operating system of the device in real time (for example, the real-time electric quantity of the device is obtained by calling the power management interface provided by the operating system of the device once every 30 seconds), so as to monitor the real-time electric quantity of the device.
In other embodiments of the present application, a battery power change event (generally, a battery power change event is triggered every time the battery power changes by 1%) may also be monitored through a system application for monitoring the battery power built in the device, so as to monitor the real-time power of the device.
In other embodiments of the present application, other methods may also be used to monitor the real-time electric quantity of the device, which is not illustrated herein. The specific implementation mode of the real-time electric quantity of the monitoring equipment is not limited.
And 120, modifying the root label style sheet of the target webpage according to the monitored real-time electric quantity value of the equipment so as to adjust the gray value of each pixel point in the target webpage.
An OLED (Organic Light Emitting diode) display is a display based on thin film display technology. An AMOLED (Active-matrix organic light-emitting diode) screen is one of the OLED screens. OLED screens have the property of self-luminescence, using very thin coatings of organic materials and glass substrates, which emit light when a current is passed through them. Each pixel of the OLED screen can be controlled independently without the need for a constant backlight.
The inventor repeatedly tests the power consumption of the OLED screen by displaying wallpapers with different colors on OLED screen equipment to find that the power consumption of the OLED screen is the least when the OLED screen displays black wallpapers, the power consumption is the least when green and other dark wallpapers are displayed, and the power consumption is the highest when white wallpapers are displayed. And by combining the display principle of the OLED screen, the OLED screen does not emit light under the condition of no power supply, and the screen displays black. Therefore, the inventor finds that the effect of saving screen power consumption can be achieved by adjusting the color of the page displayed by the OLED screen.
Specifically, in the embodiment of the application, after the real-time electric quantity value of the device is obtained, the real-time electric quantity value is used as a setting parameter of a webpage element label style in the target webpage, and the gray value of each pixel point in the target webpage is adjusted according to the setting parameter. For example, when the real-time electric quantity value of the device is greater than the preset low-electric-quantity threshold, the gray value of each pixel point in the webpage can be linearly increased along with the reduction of the real-time electric quantity of the device, so as to reduce the electric quantity consumption when the webpage is displayed; when the real-time electric quantity value of the equipment is smaller than or equal to the preset low-electric-quantity threshold value, namely the battery of the equipment is already in a low-electric-quantity state, the gray value of each pixel point in the webpage can be set to be the maximum, and the background color and the foreground color of the webpage are subjected to reverse color processing, so that the electric quantity consumption is further reduced when the webpage is displayed.
The display style of the whole webpage can be determined by the root label style of the webpage, so the gray value of each pixel point in the target webpage, the background color and the foreground color of the webpage are adjusted by modifying the follow label style of the target webpage.
And step 130, rendering the target webpage according to the modified root tag style sheet, and controlling the equipment to display the target webpage based on webpage data obtained by rendering.
And in the process of controlling the equipment to display the target webpage based on webpage data obtained by rendering, the equipment drives the luminous material at the corresponding position of the OLED screen of the equipment by using the current matched with the gray value of each pixel point in the target webpage.
For example, a target webpage is accessed on an OLED screen smart phone through a browser, the browser first obtains a page code of the target webpage and executes the page code to obtain page data. And then, rendering the page according to the obtained page data, and sending the rendered data to a display interface provided by the system of the smart phone for display. Specifically, in the embodiment of the present application, when the browser executes the code of the target webpage, the step of setting the foreground color, the background color and the gray value of the target webpage according to the obtained device real-time electric quantity value is executed, and then, the browser performs rendering on the target webpage according to the set foreground color, background color and gray value of the target webpage to obtain page data after the target webpage is adjusted.
And then, the browser sends the rendered page data to a display memory of the equipment, calls a display interface of an OLED screen and displays the page data.
As described in the previous steps, for a web page with a white background and a black foreground, when the battery of the device is in a low-power state, the web page is adjusted to be the black background and the white foreground. At this time, because the background pixel points are more than the foreground pixel points, when the background pixel points are displayed, the current does not need to be output to the screen pixel points corresponding to the pixel points, and therefore, the electric quantity consumption required by displaying the webpage can be greatly reduced.
According to the power saving method applied to the OLED screen equipment, the real-time electric quantity of the equipment is monitored by responding to the interface call of the display target webpage; then, modifying a root label style sheet of the target webpage according to the monitored real-time electric quantity value of the equipment so as to adjust the gray value of each pixel point in the target webpage; and finally, rendering the target webpage according to the modified root tag style sheet, and controlling the equipment to display the target webpage based on webpage data obtained by rendering, wherein in the process of controlling the equipment to display the target webpage based on the webpage data obtained by rendering, the equipment drives the luminous material at the corresponding position of the OLED screen of the equipment by using the current matched with the gray value of each pixel point in the target webpage, so that the power consumption of the OLED screen when the webpage is displayed can be effectively saved, and the power saving performance of the equipment is improved.
On the other hand, under the condition that screen brightness is higher, risk of screen burning and screen aging is more likely to occur, the gray value of the webpage displayed on the sub-screen is adjusted according to the real-time electric quantity value of the equipment, the pixel brightness value of the screen can be effectively reduced, risk of screen burning is reduced, screen aging is slowed down, and the service life of the screen is prolonged.
Example two
The following describes in detail a technical solution of a power saving method applied to an OLED screen device, which is disclosed in an embodiment of the present application, with reference to fig. 2. As shown in fig. 2, the method: step 210 to step 250.
For a specific implementation manner of monitoring the real-time electric quantity of the device in response to the interface call for displaying the target webpage, reference is made to embodiment one, and details are not repeated in this embodiment.
In the embodiment of the application, after the real-time electric quantity value of the device is obtained, the real-time electric quantity value is used as a setting parameter of a webpage element label style in the target webpage, and the gray value of each pixel point in the target webpage is adjusted according to the setting parameter. When the real-time electric quantity value of the equipment is larger than the preset low-electric-quantity threshold value, along with the reduction of the real-time electric quantity of the equipment, the gray value of each pixel point in the webpage can be linearly increased so as to reduce the electric quantity consumption when the webpage is displayed; when the real-time electric quantity value of the equipment is smaller than or equal to the preset low-electric-quantity threshold value, namely the battery of the equipment is already in a low-electric-quantity state, the gray value of each pixel point in the webpage can be set to be the maximum, and the background color and the foreground color of the webpage are subjected to reverse color processing, so that the electric quantity consumption is further reduced when the webpage is displayed.
And step 230, in response to that the real-time electric quantity value of the device obtained by the real-time electric quantity monitoring is smaller than or equal to a preset low-electric-quantity threshold value, performing reverse color processing on the foreground color and the background color of the target webpage by modifying parameters of the foreground color, the background color and the page gray value set in the root tag style sheet of the target webpage.
In some embodiments of the present application, the modifying the root tag style sheet of the target webpage according to the monitored real-time electric quantity value of the device to adjust the gray value of each pixel point in the target webpage includes: and in response to the fact that the real-time electric quantity value of the equipment obtained by the real-time electric quantity monitoring is smaller than or equal to a preset low-electric-quantity threshold value, performing reverse color processing on the foreground color and the background color of the target webpage by modifying parameters of setting the foreground color, the background color and the page gray value in a root tag style sheet of the target webpage, and setting the page gray value of the target webpage as the maximum value. CSS (Cascading styles lists) is used to set the display style and rules of a web page, and by modifying a row in CSS, the middle display style of all pages defined by the list changes accordingly. For example, the filter in CSS, gray () method, is used to perform gray conversion on a picture. In specific implementation, the amount of the conversion value of the gray scale (amount) may be a numerical value or a percentage, when the amount value is 100%, the gray scale of the image obtained by conversion is the largest, and when the amount value is 0%, the gray scale of the image obtained by conversion is not different from that of the original image. An amount value between 0% and 100% will cause the picture to change in gray linearly.
In some embodiments of the present application, the foreground color, the background color and the page gray value of the target webpage are set by calling the style setting method filter in the CSS, i.e., invert (1) and gray (1). It can be seen from the above method that when the original foreground color of the target web page is black and the original background color is white, the foreground color of the target web page is set to be white and the background color is set to be black by calling the above style setting method. Since most web pages have white original background color and black original foreground color, when the device battery is in a low-power state, the background color of the web pages can be adjusted to black and the foreground color can be adjusted to white by executing the above-described root tag style setting method. Taking the original web page displayed in fig. 3 as an example, the display effect of the adjusted target web page is shown in fig. 4.
And jumping to the step 250, rendering and displaying the adjusted target webpage.
In some embodiments of the present application, the modifying the root tag style sheet of the target webpage according to the monitored real-time electric quantity value of the device to adjust the gray value of each pixel point in the target webpage includes: in response to the real-time electric quantity value of the device obtained through the real-time electric quantity monitoring being larger than a preset low-electric quantity threshold value, taking the real-time electric quantity value of the device as a parameter for setting foreground color, background color and page gray value in a root label style sheet of the target webpage, and adjusting the gray value of the target webpage, wherein the foreground color is set to be inversely proportional to the real-time electric quantity value of the device, the background color is set to be directly proportional to the real-time electric quantity value of the device, and the page gray value is set to be inversely proportional to the real-time electric quantity value of the device.
Taking the monitored real-time electric quantity value of the device as x, wherein the real-time electric quantity value is that x is more than or equal to 0 and less than or equal to 1, when x is 0, the battery is in an electric quantity exhaustion state, and when x is 1, the battery is in a full electric state. Assuming that the preset low-power threshold is 20%, when the real-time power value x of the device is greater than or equal to 20%, it indicates that the device does not reach a low-power state at present, and in order to reduce the power consumption speed of the device, and simultaneously avoid the risks of screen burn-in and screen aging, and prolong the service life of the screen, in the embodiment of the application, the brightness achieved by each pixel point of the screen is reduced by modifying the gray value of each pixel point of the target webpage.
In some embodiments of the application, the foreground color, the background color and the page gray value are set by calling a style setting method filter (1-x) in the CSS, wherein x is a monitored real-time electric quantity value of the device. It can be seen from the above method that the foreground color of the target webpage is set to be inversely proportional to the device real-time electric quantity value, and the background color is set to be directly proportional to the device real-time electric quantity value. That is, when x is equal to 1 (i.e., when the battery is full), the background color of the target web page is set to white, and the foreground color (i.e., the font color) is set to black, and at this time, the gray scale value of the target web page is the minimum (i.e., the gray scale value of the target web page is the same as the original gray scale value), and the display effect of the target web page is as shown in fig. 3. When x is equal to 0 (i.e., when the battery power is low), the background color of the target web page is set to be close to black, and the foreground color (i.e., the font color) is set to be close to white, at this time, the gray value of the target web page is the largest, and the display effect of the target web page is similar to the web page display effect shown in fig. 4. When x is equal to 0.5 (i.e. when the battery level is low), the grayscale value of the target webpage is greater than the grayscale value of the original webpage, and at this time, the display effect of the target webpage is as shown in fig. 5.
And 250, rendering the target webpage according to the modified root tag style sheet, and controlling the equipment to display the target webpage based on webpage data obtained by rendering.
And in the process of controlling the equipment to display the target webpage based on webpage data obtained by rendering, the equipment drives the luminous material at the corresponding position of the OLED screen of the equipment by using the current matched with the gray value of each pixel point in the target webpage.
The specific implementation of rendering the target webpage according to the modified root tag style sheet and controlling the device to display the target webpage based on the rendered webpage data is referred to in embodiment one, and details are not repeated in this embodiment.
According to the power saving method applied to the OLED screen equipment, the real-time electric quantity of the equipment is monitored by responding to the interface call of the display target webpage; responding to the fact that the real-time electric quantity value of the device obtained through the real-time electric quantity monitoring is larger than a preset low-electric-quantity threshold value, taking the real-time electric quantity value of the device as parameters for setting foreground color, background color and page gray value in a root label style sheet of the target webpage, and adjusting the gray value of the target webpage; wherein the foreground color is set to be inversely proportional to the device real-time electric quantity value, the background color is set to be directly proportional to the device real-time electric quantity value, and the page gray value is set to be inversely proportional to the device real-time electric quantity value; responding to that the real-time electric quantity value of the equipment obtained by the real-time electric quantity monitoring is smaller than or equal to a preset low-electric-quantity threshold value, performing reverse color processing on foreground color and background color of the target webpage by modifying parameters of setting foreground color, background color and page gray value in a root tag style sheet of the target webpage, and setting the page gray value of the target webpage as a maximum value; and finally, rendering the target webpage according to the modified root tag style sheet, and controlling the equipment to display the target webpage based on the webpage data obtained by rendering, so that the power consumption of the OLED screen when the webpage is displayed can be effectively saved, and the power saving performance of the equipment is improved.
On the other hand, under the condition that screen brightness is higher, risk of screen burning and screen aging is more likely to occur, the gray value of the webpage displayed on the sub-screen is adjusted according to the real-time electric quantity value of the equipment, the pixel brightness value of the screen can be effectively reduced, risk of screen burning is reduced, screen aging is slowed down, and the service life of the screen is prolonged.

In some embodiments of the present application, a timing task may be started first, then, an operation of a user on the target webpage is detected through a trigger event of a registration screen, and when the operation of the user on the target webpage is detected, the timing task is restarted. And if the operation of the user on the target webpage is not detected, the timing task carries out accumulated timing on the webpage operation time interval of the user.
When the power saving method applied to the OLED screen device disclosed by the embodiment of the application is operated, the real-time electric quantity monitoring of the device is started firstly.
And if the user does not operate the target webpage within the preset time interval, adjusting the gray value of the displayed webpage to reduce the electric quantity consumption of the equipment.
In some embodiments of the application, the modifying the root tag style sheet of the target webpage in response to the operation interval being greater than or equal to a preset time interval to adjust the gray value of each pixel point in the target webpage includes: and performing reverse color processing on the foreground color and the background color of the target webpage by modifying parameters of setting the foreground color, the background color and the page gray value in the root tag style sheet of the target webpage, and setting the page gray value of the target webpage as the maximum value.
