Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Aiming at the problem of low image quality obtained by the fingerprint sensing solution in the prior art, the present invention provides a display control method, which is applied to a terminal, where the terminal includes an optical fingerprint touch area, an optical lens and a screen brightness spot; the optical The lens is used to focus the touch information obtained in the optical fingerprint touch area, and the screen brightness light spot is used to perform a lighting operation on the optical fingerprint touch area to make the optical fingerprint touch area glow and display; as shown in the figure 1, the display control method includes:

Step 11 : if it is detected that there is a touch operation in the touch area of the optical fingerprint, according to the relative illuminance information of the optical lens, determine the grayscale parameter information of the screen brightness light spot.

The touch operation may be a pressing operation, but is not limited thereto. Regarding "determining the gray-scale parameter information of the screen brightness light spot according to the relative illuminance information of the optical lens", it may be that each time a touch operation is detected in the optical fingerprint touch area, it is performed once according to the relative illuminance RI information The detailed process of determining the gray-scale parameter information of the screen brightness spot, such as obtaining the gray-scale parameter information according to the calculation and processing of the RI information; it can also be the corresponding relationship between the pre-stored RI information and the gray-scale parameter information (the screen brightness spot can be fixed. The gray-scale parameter information), when detecting that there is a touch operation in the optical fingerprint touch area, directly obtain the corresponding relationship (which can be fixed gray-scale parameter information), and then control the optical fingerprint touch according to the corresponding relationship. The control area is illuminated and displayed, but it is not limited to this.

Step 12: Control the optical fingerprint touch area to emit light and display according to the grayscale parameter information.

Specifically, the brightness of the middle position of the optical fingerprint touch area is lower than the brightness of the edge position. More specifically, the display brightness value of the optical fingerprint touch area may gradually increase from the middle to the edge.

In the embodiment of the present invention, the optical fingerprint touch area may be displayed as a white brightness light spot, but it is not limited to this, and may also be a light spot of other colors.

The display control method provided by the embodiment of the present invention determines the grayscale parameter information of the screen brightness light spot according to the relative illuminance information of the optical lens if a touch operation is detected in the optical fingerprint touch area. ; According to the grayscale parameter information, control the light-emitting display of the optical fingerprint touch area; in this way, the brightness of the screen brightness spot can be adapted to the relative illuminance of the optical lens. When the fingerprint sensor obtains in the optical fingerprint touch area When the touch information is exposed, a fingerprint image with uniform quality can be obtained, thereby significantly improving the quality uniformity and clarity of the fingerprint sensing image, thereby improving the fingerprint recognition rate; the image quality obtained by the fingerprint sensing solution in the prior art is well resolved. low problem.

Wherein, determining the gray-scale parameter information of the screen brightness light spot according to the relative illuminance information of the optical lens includes: determining the brightness change rule of the outgoing light of the optical lens according to the relative illuminance information of the optical lens; According to the change rule of the brightness of the outgoing light, the grayscale parameter information of the brightness spot on the screen is determined.

In this way, the grayscale parameter information of the screen brightness light spot adapted to the RI can be accurately obtained.

Specifically, the determining the grayscale parameter information of the screen brightness spot according to the brightness change rule of the outgoing light includes: determining the brightness characteristic law of the screen brightness spot according to the outgoing light brightness change law;

Correspondingly, the controlling the light-emitting display of the optical fingerprint touch area according to the grayscale parameter information includes: controlling the light-emitting display of the optical fingerprint touch area according to the brightness characteristic law.

In this way, the brightness of the screen brightness spot can be adapted to the RI, and a fingerprint image with uniform quality can be obtained when the fingerprint sensor exposes the touch information obtained through the optical fingerprint touch area, thereby significantly improving the uniform quality of the fingerprint-perceived image. Sex and clarity.

More specifically, in the embodiment of the present invention, the brightness characteristic law may be opposite to the brightness change law of the outgoing light, that is, the brightness display law of the optical fingerprint touch area is opposite to the brightness change law of the outgoing light corresponding to the RI. It is adapted to the RI, so that after the light in the touch area of the optical fingerprint reaches the sensor pixel sensing through the lens, the brightness ratio of the adjacent areas of the sensor can reach 1, that is, when the center exposure reaches the target sensing value, from the middle to the edge The sensing intensity value of the pixels will all reach the target value, showing a consistent level of overall brightness, and there will be no problem of insufficient sensing.

In this embodiment of the present invention, the terminal further includes an image sensor (which may be a fingerprint sensor) for receiving the touch information, and the absolute value of the difference between the brightness values of any two positions on the image sensor is less than a preset value value.

That is, after the light in the touch area of the optical fingerprint reaches the sensor pixel sensing through the lens, the brightness ratio of the adjacent areas of the sensor can be greater than the threshold value, and try to present the same level of overall brightness (uniform brightness).

The display control method provided by the embodiment of the present invention is further described below, and the touch operation takes the pressing operation generated by the user's finger as an example.

In view of the above technical problems, considering that the light emitted by the current fingerprint acquisition area is only a single brightness color block, before being pressed by the finger, the screen of the terminal displays the fingerprint positioning icon. It emits a green or white circular light spot, which is used as the source of the emission light source for photoelectric fingerprint identification; at present, the brightness of the emission light spot is single and uniform, forming a uniform light spot light source;

After the uniform spot light source passes through the optical lens (LENS), due to the non-uniformity of the light received by the lens, the light intensity entering the surface of the fingerprint sensor is not uniform, and there will be strong middle and weak edges, gradually from the middle to the edge. The law of weakening is the relative illuminance index of the lens. The ratio of the brightness of the periphery to the center of the lens is the relative illuminance (RI: relative illumination) index of the lens. According to the principle characteristics of the convex lens of the lens, its (RI) cannot reach 100. %, such as reaching 60%, the brightness of the uniform spot light source will not match the RI index of the lens. When the fingerprint sensor is exposed, it will cause uneven image quality, that is, the fingerprint image will appear bright in the middle and dark in the edge. Happening;

Therefore, the embodiment of the present invention provides a display control method, which can be a lighting method for an optical fingerprint, which mainly uses a gradient light spot adapted to RI instead of a uniform light spot, which can significantly improve the image quality. Uniformity, improve the problem that the brightness from the middle to the edge gradually dims (the middle is too bright, the edge is dark), improve the image quality, and improve the fingerprint recognition rate.

Specifically, it is assumed that the optical fingerprint touch area in the existing solution is the original pure color brightness spot, and the brightness spot can be pure white or other colors. The following takes the white spot as an example:

When the original pure white light spot passes through the optical lens, due to the non-uniformity of light energy received by the lens, the brightness light spot of the outgoing light on the surface of the fingerprint sensor will become bright in the middle and dark in the edges in turn.

When the gradually darkening light is sensed by the sensor pixels, the sensing intensity value of each pixel will show a large sensing value in the middle, and gradually become smaller toward the periphery (as shown in the following table). When the intermediate pixel reaches the target sensing value, the sensing intensity from the middle to the edge The value parameter gradually decreases. The intermediate sensing value is 3200, which means that the brightness is the highest and the edge is the lowest, which means underexposure occurs. If the exposure continues, there will be intermediate overexposure.

Example table of sensor pixel light sensitivity parameter values

According to the sensor sensing value of the pure color spot above, the attenuation information of the brightness change of the optical system lens from the center to the edge can be obtained, such as the attenuation ratio, if the brightness value from the center to the periphery is A1, A2, A3...An; Then the luminance change ratio K1=A2/A1; K2=A3/A2...Kn=An/An-1.

In order to make up for the problem of weak image signal due to insufficient peripheral brightness, this solution adopts a gradient light spot, and the brightness characteristic law of the light spot is just opposite to the change law of the brightness of the outgoing light.

The specific operation can be as follows: adjusting the grayscale parameters of the screen brightness light spot to realize that the light spot is dark in the middle and gradually brightens from the middle to the edge.

If the brightness grayscales from the center to the edge are B1, B2, B3...Bn in sequence; then the brightness change ratio corresponding to the grayscale value is K'n=1/Kn=Bn/Bn-1, that is, the rule of reciprocal magnification can be used. Brighten the spots in turn.

Obviously, using the above gradient light spot, after the light of the light spot reaches the sensor pixel sensing through the lens, the brightness ratio of the adjacent areas of the sensor An/An-1=Kn×(1/Kn)=1, that is, when the center exposure reaches the target sensing value At the same time, the sensing intensity value of each pixel from the middle to the edge will reach the target value, showing a consistent level of overall brightness, and there will be no problem of insufficient sensing.

It can be seen from the above that the solution provided by the embodiment of the present invention mainly solves the problem of low signal volume caused by insufficient relative illumination of the lens by changing the uniform single-brightness light spot of the current photoelectric fingerprint light spot into a certain regular gradient light spot. problem, improved fingerprint image quality, improved recognition performance and user experience.
