Accordingly, the present disclosure provides a display screen control method to at least solve the problems in the related art.

Fig. 1 illustrates a flowchart of a display control method according to an exemplary embodiment of the present disclosure.

In step S101, in response to the display page switching, it is determined whether the display page currently in the foreground is in a preset page white list.

In the terminal device described in the present disclosure, a part of pages are listed in a preset page white list in advance, and for example, page tags may be stored in the page white list of the cloud in advance, and in the case that the terminal device is started, the page white list is stored in the list of the page manager ACTIVITY MANAGER SERVICE.

For example, display pages with high power consumption may be listed in the page whitelist, e.g., display pages with too high a pure white duty cycle, pages with too high saturation, etc.

Under the condition that the display pages of the terminal equipment are switched, whether the display pages of the current terminal equipment are in a preset white list or not can be determined in advance, so that whether the current display pages need to be processed or not is judged, and the electric energy consumption caused by displaying the current pages is reduced.

Preferably, part of the application program sequence can be put into a preset application white list in advance, wherein each display page of the application program in the preset application white list is in the preset page white list.

Under the condition that the display pages are switched, in response to the condition that the display page currently in the foreground belongs to an application program outside the application white list, whether the display page currently in the foreground is in the preset page white list or not needs to be further determined.

Under the condition that the current display page in the foreground belongs to an application program in an application white list, the current display page can be directly determined to be in the preset page white list, traversing judgment on the current page is not needed, and the operation efficiency of the terminal equipment is improved.

In step S102, in the case that the display page currently in the foreground is in the preset page white list, at least one of the color parameters RGB value of the display page, the brightness of the display page, and the saturation of the display page is reduced.

The display page currently in the foreground is in a preset page white list, the fact that the current display page has larger power consumption on a display picture of the terminal equipment is represented, the display effect of the display page can be adjusted by reducing at least one of the color parameter RGB value of the display page, the brightness of the display page and the saturation of the display page, and the power consumption of the display page is reduced.

Preferably, a plurality of different page whitelists may be set according to different page adjustment strategies, in response to the display page switching, it may be determined whether the display page currently in the foreground is in any one of the preset page whitelists, and in the case that the display page currently in the foreground is in any one of the preset page whitelists, at least one of a color parameter RGB value of the display page, brightness of the display page, and saturation of the display page may be reduced according to the page adjustment strategies corresponding to the different page whitelists.

In one example, the color parameter RGB values of the preset color in the display page may be reduced if the display page currently in the foreground is in the preset first page white list. For example, for a pure white area in a display page, the color parameter RGB value of the white area can be reduced by reducing the color parameter RGB value thereof to reduce the power consumption of displaying the area for a terminal device, and for example, the hexadecimal color code of all pure white in the display page currently in the foreground can be converted from #ffffff to # FCFCFC or # FAFAFA, and the color parameter RGB value of the white area can be reduced within the user color acceptance range.

In another example, when the currently-in-foreground display page is in the preset second page white list, the color parameter RGB values of all colors of the display page can be reduced, that is, the power consumption of each color area in the currently-displayed page to the terminal device is reduced as a whole.

In another example, in the case that the currently foreground display page is on the preset third page white list, the brightness value of the display page may be reduced, so as to reduce the power consumption of all the areas in the currently displayed page to the terminal device.

According to the scheme, under the condition that the display page in the preset page white list is in the foreground, at least one of the color parameter RGB value of the display page, the brightness of the display page and the saturation of the display page is reduced, so that the power consumption of all areas in the current display page to terminal equipment is reduced.

In an optional embodiment, the reducing the color parameter RGB value of the preset color in the display page when the display page currently in the foreground is in the preset first page white list specifically includes:

And responding to the display page in the preset first page white list at the foreground position, sending a color area to be adjusted in the current display page to a drawable object drawable through a static method, and controlling drawable in the display page to redraw so as to reduce the RGB value of the color parameter of the preset color in the display page.

Specifically, the specific adjustment value of the color to be adjusted in the display page may be sent to the renderable object drawable by using the boolean static method should Decline Color, and since the specific adjustment value of the color to be adjusted is a static value, all the renderable objects drawable in the current page use the static value to perform the picture processing.

According to the scheme, the color region to be adjusted in the current display page is sent to the drawable object through the static method, and drawable in the display page is controlled to be drawn again, so that the color parameter RGB value of the preset color in the display page is reduced, and compared with the drawing performed by using the value transfer control drawable of the UI system, the calculation efficiency of the terminal equipment is improved, and the electric energy consumption of the terminal equipment is further reduced.

In an alternative embodiment, in the case that the current drawable is in the non-bitmap form, the controlling the redrawing of drawable in the display page to reduce the color parameter RGB values of the preset color in the display page includes:

redrawing color parameters of preset colors in a current display page to reduce RGB values of the color parameters of the preset colors in the display page.

Specifically, in the case where the current drawable is a non-bitmap form (bitmap) such as a color renderable object (color drawable) or a gradient color renderable object (gradient drawble), based on the getpaint and setpaint methods, color parameters of a preset color in the current display page are redrawn, for example, a hexadecimal color code of all pure white colors in the current foreground display page is converted from #ffffff to # FCFCFC or # FAFAFA.

In the case that the current drawable is in bitmap form, the controlling the redrawing of drawable in the display page to reduce the color parameter RGB values of the preset color in the display page includes:

And reducing the RGB value of the color parameter of the preset color in the bitmap through a preset color filter matrix.

Specifically, for a non-bitmap-form renderable object such as a 9-patch, the product of all drawable of the currently displayed pages can be performed through a predefined color filter matrix to adjust and reduce the color parameter RGB values of the preset color in the displayed pages, without traversing the bitmap pixels of drawable.

And then, the image information in the current display page can be sent to the bottom layer for drawing so as to be displayed in the screen of the terminal equipment.

According to the scheme, the static setting of the drawable object is directly carried out to reduce the color parameters of the preset color in the display page, the image display module surface flinger is not required to be used for drawing the display page, the calculation efficiency of the terminal equipment is improved, and the electric energy consumption of the terminal equipment is further reduced.
