Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are only a subset of the embodiments of the present disclosure, and not all embodiments. The embodiments described below with reference to the accompanying drawings are illustrative and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

The method for determining the under-screen photosensitive sensor can be applied to a scene of detecting the position of the under-screen photosensitive sensor of the terminal. The under-screen light sensor may include a light sensor and other sensors having a light sensing function.

With the continuous development of full-screen mobile phones, more and more sensors under the screen come into the visual field of people. The photosensitive sensor under the screen is used as an important component of the terminal, and provides light sensing capability for the environment for the terminal.

In the related art, it is generally required to store the precise position of the photosensitive sensor in the main board in the terminal, so as to be used as a parameter when the terminal performs a related algorithm or an optimized setting. In the related art, an off-screen photosensor is generally mounted on a terminal main board. Moreover, because the terminal main board is usually made of hard materials, the photosensitive sensor under the screen can be installed at a certain accurate position in the main board in a hard connection mode. In the related art, a certain position can be determined in the main board, the under-screen photosensitive sensor is installed at the accurate position in a hard connection mode, and further, the position is stored in the terminal so as to meet the requirements of the terminal for carrying out related algorithms or optimizing settings.

In the related art, the FPC has advantages of thin thickness, light weight, flexibility, and high flexibility. In order to make the circuit arrangement and/or device distribution inside the terminal more flexible, the terminal motherboard is usually replaced by a hard motherboard with an FPC motherboard. In the related art, the FPC main board is made of a soft material, so that the under-screen photosensitive sensor cannot be installed at a certain accurate position in the main board, and the position of the under-screen photosensitive sensor stored in the terminal and the actual position of the under-screen photosensitive sensor can deviate. For example, if the off-screen photosensor is required to be installed at the position shown in fig. 1, the actual position where the off-screen photosensor is installed may be the position shown in fig. 2 because the terminal main board is the FPC main board. According to the method, the position of the under-screen photosensitive sensor stored by the terminal is different from the actual position of the under-screen photosensitive sensor, so that the accuracy of the terminal in executing the related algorithm is influenced, and even the optimal setting of the terminal is invalid.

The embodiment of the disclosure provides a method for determining a position of an under-screen photosensitive sensor, which is used for controlling a terminal screen to respectively perform pixel row display and pixel column display, and determining a pixel row position and a pixel column position of the under-screen photosensitive sensor, which monitor that photosensitive data is greater than a preset data threshold value, in the process. The precise position of the photosensitive sensor under the screen can be determined through the pixel row position and the pixel column position.

Fig. 3 is a flowchart illustrating an off-screen photosensor position determining method according to an exemplary embodiment, which is used in a terminal as shown in fig. 3, and includes the following steps.

In step S11, the terminal screen is controlled to perform pixel row display and pixel column display, and the pixel row position and the pixel column position where the under-screen photosensitive sensor of the terminal monitors that the photosensitive data is greater than the preset data threshold are determined.

The terminal screen may be, for example, a screen having pixel row display, pixel column display, and oblique pixel display capabilities, such as an Organic Light-Emitting Diode (OLED) screen. The light sensing data monitored by the light sensing sensor under the screen may be, for example, a pixel color (RGB) value of the terminal screen, or may also be a pixel brightness value of the terminal screen.

In an example, the preset data threshold may be a minimum value of the light sensing data, and of course, may also be a light sensing data value monitored by the light sensing sensor in a case that the terminal screen does not perform pixel display.

In step S12, the position of the off-screen photosensor is determined based on the pixel row position and the pixel column position.

The method for determining the position of the photosensitive sensor under the screen can determine the accurate position of the photosensitive sensor under the screen. Furthermore, the accurate position of the photosensitive sensor under the screen is stored in the terminal, so that the accuracy of the terminal in executing related algorithms and/or optimizing settings can be improved.

In the embodiment of the disclosure, the position of the photosensitive sensor under the screen is determined by a position detection mode. Therefore, compared with a mode that the photosensitive sensor under the screen is directly installed at a certain position in the main board and the position is used as the position of the photosensitive sensor under the screen, the method has higher accuracy.

In addition, the position of the photosensitive sensor under the screen is determined by the position detection mode. Therefore, the terminal provided with the FPC mainboard can acquire the accurate position of the photosensitive sensor under the screen, and the terminal provided with the hard material mainboard can acquire the more accurate position of the photosensitive sensor under the screen.

In the embodiment of the disclosure, a terminal screen can be controlled to perform pixel row display and pixel column display in different ways. As shown in fig. 6 and 7, the terminal may include a first side end, a second side end, a third side end, and a fourth side end. The first side end is opposite to the second side end, and the third side end is opposite to the fourth side end. Further, for convenience of description, the embodiment of the present disclosure refers to an edge pixel row at a terminal first side end as a first pixel row, an edge pixel row at a terminal second side end as a second pixel row, an edge pixel column at a terminal third side end as a first pixel column, and an edge pixel column at a terminal fourth side end as a first pixel column.

In one example, the terminal screen is controlled to perform pixel row display and pixel column display respectively, and two adjacent side ends (for example, a first side end and a third side end) may be selected from four side ends of the terminal. Further, the selected side end may be used as a start end (a first side end) of line-by-line display of the pixel rows or a start end (a third side end) of column-by-column display of the pixel columns, so as to control the pixel rows of the terminal screen to be displayed line-by-line and the pixel columns of the terminal screen to be displayed column-by-column.

Fig. 4 is a flowchart illustrating another method for determining a position of an off-screen photosensor according to an exemplary embodiment, and as shown in fig. 4, step S22 of the method for determining a position of an off-screen photosensor according to the embodiment of the present disclosure is similar to the method for executing step S12 shown in fig. 1, and is not repeated here.

In step S21, the control terminal screen performs line-by-line display from the first pixel line to the second pixel line in a preset line unit, performs line-by-line display from the first pixel column to the second pixel column in a preset column unit, and determines a pixel line position and a pixel column position where the under-screen photosensor of the terminal monitors that the sensitization data is greater than a preset data threshold.

In the embodiment of the disclosure, in the process of controlling the terminal screen to perform line-by-line display from the first pixel line to the second pixel line in the preset line unit and to perform line-by-line display from the first pixel column to the second pixel column in the preset column unit, the previously displayed pixel line or pixel column may be controlled to be in the off state, so that only the pixel line of the preset line or only the pixel column of the preset column is displayed at each time point in the process of performing pixel display on the terminal screen. The method may determine each pixel row and pixel column that intersects the off-screen photosensor and thereby determine the position of the off-screen photosensor.

In another example, the terminal screen is controlled to perform pixel row display and pixel column display respectively, and four side ends of the terminal may be respectively used as a start end of pixel row line-by-line display or a start end of pixel column line-by-column display, so as to control the pixel row line-by-line display of the terminal screen and control the pixel column line-by-column display of the terminal screen.

Fig. 5 is a flowchart illustrating a further method for determining a position of an off-screen photosensor according to an exemplary embodiment, and as shown in fig. 5, step S32 of the method for determining a position of an off-screen photosensor according to the embodiment of the present disclosure is similar to the method for executing step S12 shown in fig. 1, and is not repeated here.

In step S31, the control terminal screen performs line-by-line display on the first pixel line in units of preset lines until the sensed light data monitored by the off-screen light sensor is greater than a preset data threshold, and performs line-by-line display on the control terminal screen in units of preset lines on the second pixel line until the sensed light data monitored by the off-screen light sensor is greater than the preset data threshold. And controlling the terminal screen to display the third pixel column row by row in a preset column unit until the photosensitive data monitored by the photosensitive sensor under the screen is larger than a preset data threshold value, and controlling the terminal screen to display the fourth pixel column row by row in a preset column unit until the photosensitive data monitored by the photosensitive sensor under the screen is larger than the preset data threshold value. And determining the pixel row position and the pixel column position of the photosensitive data detected by the under-screen photosensitive sensor of the terminal to be greater than the preset data threshold value.

For example, the preset row may be a single pixel row or a multi-pixel row. The preset column may be a single pixel column or a multi-pixel column. In the embodiment of the present disclosure, the position of the photosensitive sensor under the screen needs to be determined according to the pixel row position and the pixel column position. Therefore, the rows are preset by the single pixel rows, the columns are preset by the single pixel columns, the accuracy is highest, and the determined position of the photosensitive sensor under the screen is accurate.

In the embodiment of the present disclosure, since the pixels displayed on the terminal screen row by row or the pixels displayed on the terminal screen column by column are terminated when the light sensing data monitored by the light sensing sensor under the screen is greater than the preset data threshold, the display state of the previously displayed pixel row or pixel column has no influence on the process. In other words, the previously displayed pixel rows or pixel columns can be kept in the on state or adjusted to the off state. According to the method, when the photosensitive data monitored by the photosensitive sensor under the screen is larger than the preset data threshold value, the position of the pixel row and the position of the pixel column displayed by the terminal screen can be determined, and the position of the photosensitive sensor under the screen can be determined.

Fig. 6 is a diagram illustrating a control terminal screen displayed line by line in units of preset lines by a first pixel line according to an exemplary embodiment. Fig. 7 is a diagram illustrating a control terminal screen that performs column-by-column display in units of preset columns by a first pixel column according to an exemplary embodiment. As shown in fig. 6 and 7, in the process of controlling the terminal screen to perform line-by-line display or column-by-column display, if there is an intersection between the pixel line or the pixel column displayed on the terminal screen and the under-screen photosensor, the photosensitive data monitored by the under-screen photosensor will change significantly (for example, the monitored photosensitive data is greater than the preset data threshold). The terminal can record pixel rows or pixel columns displayed by the terminal when the photosensitive data monitored by the photosensitive sensor under the screen is larger than the preset data threshold value in the mode, and accordingly the position of the photosensitive sensor under the screen is determined.

Of course, the method for determining the position of the off-screen photosensor according to the embodiment of the present disclosure may also perform pixel row display and pixel column display in other manners, which is not specifically limited in the present disclosure.

The method for determining the position of the under-screen photosensitive sensor provided by the embodiment of the disclosure can determine the pixel row position and the pixel column position of the under-screen photosensitive sensor of the terminal, where the monitored photosensitive data of the under-screen photosensitive sensor is greater than the preset data threshold, under the condition that the screen of the terminal is controlled to perform pixel row display and pixel column display respectively. Further, the position of the photosensitive sensor under the screen can be determined according to the determined pixel row position and the determined pixel column position.

In one example, the location of the off-screen photosensor may be determined by the edge vertex coordinates of the intersection pixel area formed between the pixel row location and the pixel column location.

Fig. 8 is a flowchart illustrating a method for determining the position of an off-screen photosensor based on pixel row positions and pixel column positions, as shown in fig. 8, according to an exemplary embodiment, including the following steps.

In step S41, the edge vertex coordinates of the intersection pixel area formed between the pixel row position and the pixel column position are determined.

In step S42, the size of the coordinate area surrounded by the edge vertex coordinates in the screen is determined.

In step S43, the position of the off-screen photosensitive sensor is determined based on the coordinate area size and the size of the off-screen photosensitive sensor.

In the embodiment of the disclosure, the size of the under-screen photosensor can be stored in the terminal in a pre-stored manner, so as to be called when the position of the under-screen photosensor needs to be determined according to the size of the under-screen photosensor.

In an embodiment, the determining the coordinate area surrounded by the edge vertex coordinates in the screen may be controlling the terminal screen to perform line-by-line display by a first pixel row to a second pixel row in a preset line unit, and controlling the terminal screen to perform line-by-line display by a first pixel column to a second pixel column in a preset column unit. The preset rows may be any number of pixel rows, and the preset columns may also be any number of pixel columns. In this case, it may be determined that the pixel row or the pixel column displayed by the terminal is displayed when the sensed data monitored by the on-screen sensor is greater than the preset data threshold. Further, a pixel row area composed of a plurality of pixel row positions and a pixel column area composed of a plurality of pixel column positions may be determined in the manner shown in fig. 9, and an intersection pixel area between the pixel row area and the pixel column area may be determined as a coordinate area (an area where the under-screen photosensor is located) surrounded by edge vertices, that is, a black rectangular area shown in fig. 9.

In another embodiment, a coordinate area surrounded by the edge vertex coordinates in the screen is determined, and the preset row may be set as a single pixel row and the preset column may be set as a single pixel column. And further, the terminal screen is controlled to be displayed line by the first pixel line in a preset line unit until the photosensitive data monitored by the photosensitive sensor under the screen is larger than a preset data threshold value, and the terminal screen is controlled to be displayed line by the second pixel line in the preset line unit until the photosensitive data monitored by the photosensitive sensor under the screen is larger than the preset data threshold value. And the control terminal screen performs row-by-row display by the third pixel row in a preset row unit until the photosensitive data monitored by the photosensitive sensor under the screen is greater than a preset data threshold value, and performs row-by-row display by the fourth pixel row in the preset row unit until the photosensitive data monitored by the photosensitive sensor under the screen is greater than the preset data threshold value. In this case, it may be determined that the pixel row or the pixel column displayed by the terminal is when the sensed data monitored by the on-screen sensor is greater than the preset data threshold. Further, intersection pixels between pixel row positions and pixel column positions may be determined in the manner shown in fig. 10, and a coordinate area (an area where the on-screen photosensor is located) surrounded by edge vertices may be determined in the manner that the intersection pixels are determined as the edge vertices.

In another embodiment, the coordinate region defined by the edge vertex coordinates in the screen may be a preset row set as a multi-pixel row (e.g., a two-pixel row), and a preset column set as a multi-pixel column (e.g., a two-pixel column). And further, controlling the terminal screen to display line by the first pixel line in a preset line unit until the photosensitive data monitored by the photosensitive sensor under the screen is greater than a preset data threshold value, and controlling the terminal screen to display line by the second pixel line in the preset line unit until the photosensitive data monitored by the photosensitive sensor under the screen is greater than the preset data threshold value. And the control terminal screen performs line-by-line display by the third pixel line in a preset line unit until the photosensitive data monitored by the photosensitive sensor under the screen is greater than a preset data threshold value, and performs line-by-line display by the fourth pixel line in the preset line unit until the photosensitive data monitored by the photosensitive sensor under the screen is greater than the preset data threshold value. In this case, it may be determined that the pixel row or the pixel column displayed by the terminal is displayed when the sensed data monitored by the on-screen sensor is greater than the preset data threshold. Further, in the manner shown in fig. 11, the edge vertex of the intersection pixel region is determined, and thus the coordinate region (the region where the on-screen photosensor is located) surrounded by the edge vertex is determined.

In one example, in the case of determining a coordinate area surrounded by the edge vertex coordinates, the size of the coordinate area may be compared with the size of the off-screen photosensitive sensor, and the position of the off-screen photosensitive sensor may be determined according to the comparison result of the sizes of the coordinate area and the off-screen photosensitive sensor.

Fig. 12 is a flowchart illustrating a method of another method for determining a position of an off-screen photosensor according to a pixel row position and a pixel column position according to an exemplary embodiment, and as shown in fig. 12, steps S51 and S52 in the method for determining a position of an off-screen photosensor according to an exemplary embodiment of the present disclosure are similar to the method for executing steps S41 and S42 shown in fig. 8, and are not repeated here.

In step S53a, if the coordinate area size is the same as the size of the off-screen photosensitive sensor, the coordinate area is determined as the position of the off-screen photosensitive sensor.

In step S53b, if the coordinate area size is different from the size of the off-screen photosensor, the tilt angle of the off-screen photosensor with respect to the coordinate area is determined based on the coordinate area size and the size of the off-screen photosensor, and the position of the off-screen photosensor is determined based on the tilt angle.

In the embodiment of the disclosure, if it is determined that the size of the coordinate area is the same as the size of the photosensitive sensor under the screen, it is determined that the coordinate area coincides with the area where the photosensitive sensor under the screen is located, and then the coordinate area is directly determined as the position of the photosensitive sensor under the screen. If the size of the coordinate area is different from the size of the photosensitive sensor under the screen, the coordinate area is partially overlapped with the area where the photosensitive sensor under the screen is located, and the accurate position of the photosensitive sensor under the screen needs to be further determined by determining the inclination angle between the coordinate area and the area.

In the method for determining the position of the photosensitive sensor under the screen provided by the embodiment of the disclosure, the size of the coordinate area and the size of the photosensitive sensor under the screen are determined, which is equivalent to determining the side length of each side of the coordinate area and determining the side length of each side of the photosensitive sensor under the screen. In one example, in the case that the size of the coordinate area is different from the size of the off-screen photosensor, the inclination angle of the off-screen photosensor relative to the coordinate area can be determined by means of geometric operation. For example, as shown in fig. 13, in the case of determining the coordinate region size (one side is a, the other side is B) and the size of the photosensitive sensor under the screen (one side is a, the other side is B), it is possible to pass through

And

the values of x and y are determined, and the length of each line segment in the coordinate region is determined. Furthermore, the upper acute angle of the lower right triangle can be calculated through the side lengths A-x, B-y and a of the three sides of the lower right triangle. Since this angle is the same as the inclination angle of the sensor with respect to the coordinate region, this angle is the inclination angle of the sensor with respect to the coordinate region. In addition, the inclination angle of the under-screen photosensor relative to the coordinate area may also be determined in other ways, which is not specifically limited by the present disclosure.

In the embodiment of the disclosure, the position of the photosensitive sensor under the screen in the coordinate area can be determined in a pixel oblique line display mode under the condition that the inclination angle of the photosensitive sensor under the screen relative to the coordinate area is determined. Here, for convenience of description, any diagonal side end matching the inclination angle is referred to as a first diagonal side end, and the edge pixel diagonal line at the terminal first diagonal side end is referred to as a first pixel diagonal line.

Fig. 14 is a flowchart illustrating a method for determining the position of an off-screen photosensor based on a tilt angle according to an exemplary embodiment, as shown in fig. 14, including the following steps.

In step S61, the terminal screen is controlled to perform oblique line-by-oblique line display by the first pixel oblique line in a preset oblique line unit at an oblique angle until the sensed data monitored by the photosensitive sensor under the screen is greater than a preset data threshold.

In step S62, it is determined that the off-screen photosensor of the terminal monitors the diagonal position of the pixel where the sensitization data is greater than the preset data threshold, and determines the length corresponding to the intersection pixel line segment formed between the diagonal position of the pixel and the coordinate region.

In step S63, if the length corresponding to the intersection pixel line segment matches the side length of the off-screen photosensor, the endpoint coordinates of the intersection pixel line segment are determined as the vertex coordinates of the off-screen photosensor, and the position of the off-screen photosensor is determined based on the vertex coordinates of the off-screen photosensor.

In one example, the off-screen photosensor may have multiple poses within the coordinate region for the same tilt angle. For example, the off-screen photosensor may be in two poses within the coordinate region as shown in fig. 15 and 16. In this case, the terminal screen may be controlled to perform diagonal pixel display according to the determined tilt angle.

In one embodiment, if the off-screen photosensor is in the posture as shown in fig. 15 in the coordinate region, the terminal screen may be controlled to display in diagonal lines by the first pixels in units of preset diagonal lines in the manner as shown in fig. 17 and 18. In the process of performing pixel-by-pixel diagonal display on the terminal screen, controlling the under-screen photosensor to monitor the photosensitive data, and further determining that the pixels displayed on the terminal screen are diagonal (the pixels diagonal tangent to the under-screen photosensor in fig. 17 and 18) when the under-screen photosensor monitors that the photosensitive data is greater than a preset data threshold. In this case, an intersection pixel line segment (a bold line segment in fig. 17 and 18) formed between the diagonal line of the pixel and the coordinate region is determined, and the length corresponding to the line segment is compared with the side length of the photosensitive sensor under the screen. Further, when it is determined that the length corresponding to the intersection pixel line segment matches the side length of the on-screen photosensor, the coordinates of the end points of the intersection pixel line segment (the end points of the bold line segment in fig. 17) are determined as the coordinates of the vertex of the on-screen photosensor, so as to determine the accurate position of the on-screen photosensor.

According to the method for determining the position of the under-screen photosensitive sensor, the pixel row position and the pixel column position of the intersection part of the under-screen photosensitive sensor can be determined by controlling the terminal screen to respectively perform pixel row display and pixel column display, and the approximate area of the under-screen photosensitive sensor in the terminal screen is determined according to the pixel row position and the pixel column position. Further, whether the approximate area is the accurate position of the under-screen photosensitive sensor can be judged according to the size of the under-screen photosensitive sensor stored in advance and the size of the determined coordinate area. And if the sizes of the two are the same, determining the coordinate area as the accurate position of the under-screen photosensitive sensor, and if the sizes of the two are different, further determining the posture of the under-screen photosensitive sensor in the coordinate area so as to determine the accurate position of the under-screen photosensitive sensor. By the method, the terminal can know the accurate position of the photosensitive sensor under the screen, so that the terminal can complete the algorithm or the optimized setting related to the accurate position with higher accuracy.

Based on the same conception, the embodiment of the disclosure also provides a device for determining the position of the photosensitive sensor under the screen.
