Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
According to an aspect of the embodiments of the present invention, there is provided a method for adjusting screen backlight, which is applied to a mobile terminal having a fingerprint identification area on a display screen, wherein the display screen further includes other areas except the fingerprint identification area.
As shown in fig. 1, the method of adjusting the screen backlight includes:
That is, if it is detected that the fingerprint acquisition function is turned on, a mask having a predetermined color is displayed on a region (hereinafter, referred to as a non-fingerprint recognition region) other than the fingerprint recognition region on the display screen, and is overlaid on an image displayed in the other region to reduce the brightness of the other region.
Because fingerprint identification needs high-intensity backlight to collect clearly visible fingerprint images, the brightness of a display screen needs to be increased to the brightness (generally the maximum brightness which can be set by a system) required by optical fingerprint identification, and in order to reduce the dazzling problem caused by the overhigh brightness of the whole display screen, when the fingerprint acquisition function is detected to be started, a mask is displayed in a non-fingerprint identification area, the mask is enabled to cover all the images displayed in the non-fingerprint identification area, and because the mask has the preset color which can reduce the backlight brightness transmitted from the non-fingerprint identification area, although the brightness of the non-fingerprint identification area is still the brightness required by fingerprint identification, because a layer of the mask with the preset color is covered, the light transmitted from the display screen can be weakened, and the brightness of the non-fingerprint identification area is reduced, therefore, the area of the highlight area on the display screen can be greatly reduced, and the dazzling problem caused by the highlight of the whole screen is reduced.
And 102, controlling the mask to be hidden when the mobile terminal closes the fingerprint acquisition function.
When detecting that the fingerprint acquisition function is closed, the mask is hidden, so that the mask is prevented from influencing the normal display of the display screen.
In the embodiment of the present invention, a dark color can be selected as a preset color, such as black, brown, gray, and the like, and one or more preset colors can be provided in one mask, and the specific situation can be designed according to actual requirements.
The mask described herein can also be understood as a layer of software window, which is the same as the window of the application program in any mobile terminal, except that the window only has a preset color and does not display other contents, and the software window is overlaid on the windows of all the application programs.
Further, in the embodiment of the present invention, when the mask is covered on the non-fingerprint identification area, in order to prevent the mask from affecting the user's view of the image of the non-fingerprint identification area, the transparency of the mask may be adjusted to make the mask have a certain transparency, that is, the mask having a preset color and a preset transparency is displayed in the non-fingerprint identification area, so that the brightness of the light transmitted from the display screen may be reduced to different degrees (generally, the smaller the transparency value is, the better the attenuation effect of the light transmitted from the display screen is), and the user may view the content displayed in the non-fingerprint identification area. Wherein, the transparency of the mask can be designed according to actual requirements.
Further, in the embodiment of the present invention, when the mask is covered on the non-fingerprint identification area, in order to enable the mask not to affect the user's view of the image of the non-fingerprint identification area and enable the color of the display screen to conform to the daily use color of the user, a black mask having a preset transparency may be selected to be used, that is, the black mask having the preset transparency is displayed in the non-fingerprint identification area.
By controlling the transparency of the mask, the brightness of the light transmitted from the display screen can be reduced to different degrees (the smaller the general transparency value is, the better the weakening effect of the light transmitted from the display screen is), the user can see the image in the non-fingerprint identification area, and the preset image is black filled, so that when the black mask with different transparencies covers the non-fingerprint identification area, the brightness adjustment of the non-fingerprint identification area can be more similar to the normal brightness adjustment, and the brought visual effect is more in line with the use habit of the user on the mobile terminal.
Further, in the embodiment of the present invention, when it is detected that the fingerprint capturing function is turned on, the backlight brightness of the display screen is further increased to a first preset brightness value required for optical fingerprint recognition, and after the mask is displayed in the non-fingerprint recognition area, the first preset brightness value in the non-fingerprint recognition area can be decreased to a second preset brightness value by controlling the transparency of the mask.
The second preset brightness value is the backlight brightness to be reduced after the backlight brightness of the non-fingerprint identification area is increased to the first preset brightness value.
Preferably, the second preset brightness value is the same as or similar to the brightness of the backlight of the non-fingerprint identification area increased to the brightness before the first preset brightness value, so that the brightness of the non-fingerprint identification area can be kept unchanged or changed insignificantly, and the problem of flashing backlight of the display screen caused by the process of brightness changing and dimming is avoided.
And determining the preset transparency of the mask according to the first preset brightness value and the second preset brightness value. When the first preset brightness value is the highest brightness value (i.e. 255) that can be set by the system, the relationship between the transparency of the mask and the second preset brightness value can be assumed as:
y＝a1x+a2x2+a3x3+…+anxn
wherein y represents the calculated transparency of the mask, and the value range is [0, 1 ]](ii) a x represents a second preset brightness value with the value range of 0, 255]；a1、a2、…、anFitting can be performed through experiments and experimental data.
Further, when the fingerprint collection function is detected to be turned off, the system brightness of the display screen is restored to the system brightness before fingerprint identification, and in order to avoid normal display of the display screen by the mask, the mask can be removed or set to be completely transparent.
In summary, according to the method for adjusting the screen backlight provided by the embodiment of the present invention, when it is detected that the mobile terminal starts the fingerprint acquisition function, a mask with a preset color is displayed on the other area except the fingerprint identification area in the display screen, and the light transmitted from the other area except the fingerprint identification area is weakened through the mask, so that the backlight brightness of the other area except the fingerprint identification area is reduced, thereby greatly reducing the area of the highlight area on the display screen, implementing the local backlight adjustment of the screen, not only ensuring the identification rate of the optical fingerprint, but also reducing the dazzling problem caused by the highlight of the whole display screen. In addition, when the brightness of the non-fingerprint identification area is reduced to the brightness before fingerprint identification when the mask is used for fingerprint identification, the problem of flashing backlight caused by the process that the display screen is lightened and darkened can be avoided. Furthermore, when the fingerprint collection function is detected to be closed, the mask is controlled to be hidden, and the mask is prevented from influencing the normal display of the display screen.
According to another aspect of the embodiments of the present invention, there is provided a mobile terminal, including on a display screen thereof: a fingerprint identification area and other areas than the fingerprint identification area.
