The light sensor is a component that can detect the light intensity. The light sensor can detect the current brightness of the mobile terminal and feed it back to the processor of the mobile terminal, so as to realize automatic adjustment of the screen brightness.

The present invention will be described below with specific embodiments. Of course, the present invention is not limited to these specific embodiments.

Example 1

FIG. 2 is a schematic flowchart of a method corresponding to the first embodiment of the brightness adjustment method of the present invention, and the brightness adjustment method is applied to a mobile terminal.

In this embodiment, the mobile terminal is provided with a light sensor, and the light sensor is arranged below the display area corresponding to the display screen. The bottom of the display area can be any position below the display area of the display screen, and the protective layer below the display area An opening is provided, and the photosensitive sensor is arranged at a lower position corresponding to the opening.

In this embodiment, optionally, as shown in FIG. 3 , the light sensing sensor 200 is arranged below the edge position close to the display area. It can avoid the interference of the content displayed on the display screen of the mobile terminal, and collect light brightness information more effectively, so as to further adjust the brightness of the display screen, so that the brightness of the display screen is within a reasonable range, and prevent the display screen from being too bright for a long time. The resulting screen burn-in.

In this embodiment, the cross-sectional position of the light sensor 200 is shown in FIG. 4 . The display screen 300 includes a cover glass 310 , a screen body 320 and a protective layer 330 . The cover glass 310 , the screen body 320 and the protective layer 330 are self-contained The layers are stacked in sequence from top to bottom, an opening is provided on the protective layer 330, and a photosensitive sensor 200 is provided on the integrated circuit IC layer 340 (Integrated Circuit, IC) corresponding to the position below the opening. On the corresponding IC layer below the layer opening position, the light sensor 200 can avoid the influence of foam and vinyl when collecting light brightness data, so as to further adjust the brightness of the display screen, so that the brightness of the display screen is within a reasonable range.

In this embodiment, a preset identification component is further provided below the display area corresponding to the display screen of the mobile terminal.

In this embodiment, the preset identification component is disposed on the corresponding integrated circuit IC layer below the display area of the mobile terminal.

Referring to Figure 2, the brightness adjustment method includes:

Step S210, obtaining the current brightness value corresponding to the display screen through the light sensor.

The brightness of the display screen of the mobile terminal is too low during use, so that the user cannot view the displayed content. The brightness of the display screen is too high, on the one hand, it is easy to cause damage to the user's eyesight, and on the other hand, it is easy to cause the display screen to be at high brightness for a long time. The screen components are aging, so it is necessary to adjust the brightness of the display screen. By setting the light sensor, the mobile terminal can obtain the current brightness value corresponding to the display screen, which lays a foundation for the subsequent brightness adjustment of the display screen.

Step S220: Determine the brightness adjustment range corresponding to the display screen according to the brightness range of the recognition operation corresponding to the preset recognition component and the relative position of the preset recognition component relative to the light sensor.

The mobile terminal is generally provided with a preset identification component, and the preset identification component can obtain the brightness range of the identification operation corresponding to the preset identification component, wherein the preset identification component has a certain required range for the brightness of the display screen when performing the identification operation.

At different positions of the preset recognition component relative to the light sensor, the corresponding visible light transmittance and the corresponding light sensitivity are different, which in turn causes the brightness range of the recognition operation corresponding to the preset recognition component to change. For the brightness adjustment range corresponding to the screen, in addition to the brightness range of the reference recognition job, it is also necessary to consider the relative position of the preset recognition component relative to the light sensor for conversion processing.

Therefore, when determining the brightness adjustment range of the current display screen, it is necessary to consider the brightness range of the recognition operation and the relative position of the preset recognition component relative to the light sensor to achieve the ideal effect.

Wherein, as shown in FIG. 5 , in this embodiment, the preset identification component includes an optical identification sensor, the optical identification sensor is disposed at the lower position corresponding to the opening, and the optical identification sensor and the light sensing sensor are disposed in a horizontal phase. adjacent location, the step S220 includes:

Step S222 , obtain the corresponding minimum identification operation brightness value according to the identification operation brightness range of the optical identification sensor, and use the minimum identification operation brightness value as the lower limit value of the brightness adjustment range corresponding to the display screen.

Among them, when the optical recognition sensor performs the recognition operation, there is a certain required range for the brightness of the display screen, so the brightness range of the recognition operation corresponding to the optical recognition sensor can be obtained, and the minimum brightness value of the recognition operation corresponding to the optical recognition sensor can be obtained correspondingly.

Further, since the optical recognition sensor and the light-sensing sensor are arranged at the lower position corresponding to the same opening and are in horizontally adjacent positions, the corresponding visible light transmittance and the corresponding light-sensing amount are basically the same, and the optical recognition minimum recognition operation brightness value can be directly determined. As the lower limit value of the brightness adjustment range corresponding to the display screen, as the lower limit value of the brightness adjustment range, it can ensure the normal identification operation of the optical identification sensor while optimizing the brightness.

Among them, the optical identification sensor and the light sensing sensor are arranged at the lower position corresponding to the same opening and in a horizontally adjacent position, the positions are more reasonable, and one less opening is needed to save the process and cost.

In step S224, the preset multiple of the brightness value of the lowest identification operation is used as the upper limit value of the brightness adjustment range corresponding to the display screen.

Wherein, on the basis of determining the lower limit value of the brightness adjustment range, a preset multiple of the brightness value of the lowest identification operation may be used as the upper limit value of the brightness adjustment range.

Wherein, the value of the preset multiple is usually greater than 1 and not more than 1.3.

Optionally, in this embodiment, the preset multiple takes a value of 1.3, that is, the upper limit of the brightness adjustment range is 1.3 times the brightness value of the lowest recognition operation.

For example, if the preset recognition component is an optical fingerprint recognition component, and the minimum recognition operation brightness value of the optical fingerprint recognition component is usually 600 nits, the lower limit of the brightness adjustment range can be determined to be 600 nits. Further, the preset minimum recognition operation brightness value can be set. The multiple is used as the upper limit of the brightness adjustment range corresponding to the display screen. Here, 1.3 times may be taken, that is, 780nit is used as the upper limit of the brightness adjustment range, where nit is the unit of brightness, 1nit=1 canterla/square meter, and the brightness refers to the unit projection Luminous intensity over the area.

By determining the upper limit of the brightness adjustment range to be 1.3 times the brightness value of the minimum recognition operation, it can effectively slow down the screen aging caused by the long-term high brightness of the display screen while ensuring the preset recognition components.

Step S226: Determine the corresponding brightness adjustment range according to the lower limit value of the brightness adjustment range and the upper limit value of the brightness adjustment range.

In step S230, it is judged whether the current brightness value belongs to the brightness adjustment range, if yes, go to step S240; if not, go to step S250.

After obtaining the current brightness value and the recognition job brightness range through the light sensor 200, the current brightness value can be further compared with the recognition job brightness range to determine whether the current brightness value is within the recognition job brightness range corresponding to the preset recognition component.

Step S240, keeping the current brightness value unchanged.

If the current brightness value is within the brightness range of the recognition operation, the current brightness value is within the normal and reasonable brightness range, and the mobile terminal can keep the current brightness value unchanged. The aging process of the screen is relatively slow, and the service life of the display screen is relatively prolonged.

In one embodiment, the preset identification component is an optical fingerprint identification component. If the current brightness value is within the brightness range of the identification operation, the preset identification component can work normally, and the aging process of the display screen can be relatively slowed down, extending the display time. life of the screen.

Step S250, adjust the corresponding brightness of the display screen to be within the brightness adjustment range.

After the mobile terminal obtains the current brightness value corresponding to the display screen through the light sensor 200, the current brightness value is compared with the brightness adjustment range. If the current brightness value does not belong to the brightness adjustment range, the current brightness value is not within the normal and reasonable brightness range. , the mobile terminal needs to adjust the corresponding brightness of the display screen at this time.

Among them, when the current brightness value is lower than the brightness adjustment range, the preset recognition component cannot work, and the mobile terminal lights up more pixel units to increase the corresponding brightness of the display screen to further ensure that the preset recognition component can work normally; the current brightness value When it is higher than the brightness adjustment range, the preset recognition component can work, but because the brightness of the display screen is too high, the aging of the screen luminescent material will be further aggravated if it is in a high brightness state for a long time. At this time, the corresponding brightness of the display screen needs to be appropriately reduced. , to keep it within the brightness adjustment range, which can relatively slow down the aging process of the display screen, relatively extend the service life of the display screen, and ensure that the recognition components can perform normal recognition operations.

In one embodiment, the display screen is an OLED display screen, and the preset identification component is an optical fingerprint identification component including an optical identification sensor. Since the optical identification sensor is disposed below the display area corresponding to the display screen, the optical identification sensor and the light sensing sensor are both disposed at The lower position corresponding to the opening, and the optical recognition sensor and the photosensitive sensor are set in horizontally adjacent positions. If the recognition operation is to be performed normally, the brightness of the display screen needs to be kept within the corresponding brightness adjustment range, because the OLED display screen adopts The organic light-emitting diodes are made of OLED. Therefore, when the current brightness value corresponding to the display screen obtained by the light sensor 200 is lower than the brightness adjustment range, more organic light-emitting diodes are turned on or the light-emitting brightness of the light-emitting unit is increased to increase the corresponding brightness of the display screen. , so that the optical identification sensor can work normally; when the current brightness value is higher than the brightness adjustment range, although the optical fingerprint identification component can work, but due to the excessive brightness of the display screen, the aging degree of the screen luminescent material OLED will be further aggravated. Reducing the number of organic light-emitting diodes or reducing the brightness value of the corresponding light-emitting unit can appropriately reduce the corresponding brightness of the display screen to keep it within the brightness adjustment range, and further reduce the aging process caused by the display screen in a high-brightness state. Display the service life of the screen, and at the same time can ensure that the identification component can perform the identification operation normally.

The light sensor 200 and the preset identification component of the mobile terminal are arranged below the display area corresponding to the display screen, the protective layer under the display area is provided with an opening, and the light sensor 200 is arranged at the opening. The above-mentioned brightness adjustment method determines the brightness adjustment range corresponding to the display screen according to the brightness range of the recognition operation corresponding to the preset recognition component and the relative position of the preset recognition component relative to the light sensor, and judges the current brightness adjustment range. Whether the brightness value belongs to the brightness adjustment range, if yes, keep the current brightness value unchanged; if not, adjust the corresponding brightness of the display screen to the brightness adjustment range, which can recognize the recognition operation of the component according to the preset The brightness range determines the brightness adjustment range, and further optimizes and adjusts the brightness of the display screen according to the above-mentioned brightness adjustment range, so that the brightness of the display screen is within a reasonable range. Screen burn-in caused by high brightness prolongs the life of the display screen.
