With the development of the full screen technology, following Liu Haibing, a water drop screen, a through hole screen and a blind hole screen, an under-screen camera scheme capable of realizing the full screen is generated; the camera is positioned below an OLED (organic light-Emitting Diode) display screen, and the display screen can ensure normal display effect and light transmission effect of the camera.

In the related art, in the light emitting unit matrix of the display screen, the pixel arrangement in each light emitting unit has repeatability, so that each light emitting unit only needs to be locally and respectively rendered, and each light emitting unit can be suitable for the same rendering process, but when the arrangement modes of the pixels in each light emitting unit are different and do not have any regularity, the same rendering mode is adopted to process each light emitting unit, which can result in poor image display effect.

Embodiment two:

The present embodiment provides a display control method, which is executed by the processing device in the above-described electronic system; the processing device may be any device or chip having data processing capabilities. The processing equipment can independently process the received information, can also be connected with a server, and can jointly analyze and process the information and upload the processing result to the cloud. As shown in fig. 2, the method comprises the steps of:

Step S202, obtaining an image to be processed and pixel arrangement information of a light emitting unit of a target display device; the target display device is used for displaying at least one part of image area of the image to be processed; the light emitting unit in the target display device has a plurality of pixel arrangements.

In actual implementation, the terminal can shoot to acquire the image to be processed, and the terminal can be an electronic device with an under-screen camera such as a mobile phone or an iPad; the following description will take the example of capturing an image to be processed by a mobile phone, and the following two methods can be adopted: in the first mode, an image is shot through the mobile phone, and the image can be understood as the image to be processed; the whole display screen of the mobile phone can be understood as the target display device, and at least one part of image area of the image can be displayed through the whole display screen of the mobile phone; at least a part of the image area can be understood as an image area which is displayed corresponding to a designated display area of the whole display screen of the mobile phone, and the designated display area can be understood as a small part of the whole display screen of the mobile phone, namely a small display screen corresponding to an under-screen camera; in the second mode, in the whole display screen of the mobile phone, a small display screen corresponding to the under-screen camera can be understood as the target display device; the image to be processed can be understood as a small part of the images shot by the mobile phone, which need to be displayed by the target display device, and can also be understood as a small part of the images corresponding to a small display screen corresponding to the under-screen camera; at least a portion of the image area of the small portion of the image may be displayed through the small display screen; at least a part of the image area can be understood as an image area corresponding to a designated display area of the small display screen, the designated display area can be understood as an entire display area of the target display device, and the at least a part of the image area corresponds to a small part of the image displayed by the target display device.

The above-mentioned target display device generally includes a plurality of light emitting units, each of which generally includes a plurality of pixels, and it should be noted that the pixels in the light emitting units of the target display device are different concepts from the pixels in the image; taking the target display device as a display screen for example, the pixels in the light-emitting units of the display screen are physical structures, and the image pixels are actually integral units or elements in the image which can be observed by human eyes and the like. Such as RGB pixels, RGBW pixels, RYYB pixels, or RGBC pixels, etc., may be included in the light emitting unit. Taking an example of the light-emitting unit including RGB pixels, the light-emitting unit is generally composed of R, G, B pixels, and the light-emitting unit has corresponding display parameters, such as various colors, brightness, and the like, by adjusting parameters of R, G, B pixels and overlapping the parameters. In practical implementation, for example, R, G, B pixels in the light-emitting unit may be implemented by light-emitting diodes with R, G, B colors, the light-emitting diodes with the three colors together form the light-emitting unit, parameters such as brightness of the light-emitting diodes corresponding to each of the three colors of R, G, B may be adjusted, and when the light with the three colors are overlapped with each other, the colors are mixed, so that the colors and the brightness of the light-emitting unit are changed, and thus the light-emitting unit emits light with corresponding colors and brightness through R, G, B pixels together. In an embodiment, in the display area of the target display device, the number and types of pixels included in each light emitting unit are the same, for example, each light emitting unit includes 3 pixels, and the 3 pixels are R, G, B pixels respectively, but the embodiment is not limited thereto, and each light emitting unit may also include other numbers and types of pixels, which are not described herein again. In an embodiment of the present invention, the pixel arrangement in at least one light emitting unit in the display area corresponding to the target display device is different from the pixel arrangement in other light emitting units. Or the pixel arrangement in all the light emitting units corresponding to the target display device is different. For example, the pixel arrangement information of part or all of the light emitting units in the display area corresponding to the target display device has a difference, and generally does not have any regularity. For example, taking an example in which RGB pixels are included in the light emitting units, the RGB pixels in one light emitting unit may be arranged in a lateral order, the RGB pixels in the other light emitting unit may be arranged in a longitudinal order, or in a triangular order, or the like. For example, the pixel arrangement information of the light emitting unit may further include a size parameter, a shape parameter, a posture parameter, or a distance parameter of the pixel. In an embodiment, the RGB pixels in each light emitting unit may have different size, shape, posture or distance parameters, for example, by using R, G, B pixels in the light emitting unit as light emitting diodes of R, G, B three colors as examples, at least one parameter of the size, shape, rotation angle or arrangement distance of the light emitting diodes of three colors and the relative position relationship may be different.

In view of the variability of the pixel arrangement information in the different light emitting units, when display control is required for at least a part of the image area of the image to be processed, the pixel arrangement information of each light emitting unit of the target display device needs to be acquired in advance.

Step S204, adjusting the pixel parameters of the light emitting units of the target display device according to the pixel arrangement information of the light emitting units.

The above pixel parameters may be understood as related parameters of each pixel in each light emitting unit, such as luminance values, for example, taking an RGB pixel included in a light emitting unit as an example, the pixel parameters may include related parameters such as a luminance value of an R pixel, a luminance value of a G pixel, and a luminance value of a B pixel; considering different pixel arrangement information of different light emitting units, pixel parameter adjustment of the light emitting units of the target display device is affected, and in actual implementation, the pixel parameters of each light emitting unit need to be adjusted according to the pixel arrangement information of each light emitting unit.

Step S206, displaying at least a part of the image area by the adjusted target display device.

And after the pixel parameters of the light emitting unit of the target display device are adjusted, displaying at least part of the image area in the image to be processed through the adjusted target display device.

According to the display control method provided by the embodiment of the invention, the light-emitting unit of the target display device has various pixel arrangement information; when image display control is performed, firstly acquiring an image to be processed and pixel arrangement information of a light emitting unit of a target display device; according to the pixel arrangement information of the light emitting unit, adjusting the pixel parameters of the light emitting unit of the target display device; and displaying the at least one part of image area by the adjusted target display device. In this mode, the pixel parameters of the light emitting unit are adjusted based on the pixel arrangement information of the light emitting unit of the target display device; even if the light emitting units in the target display device have various pixel arrangements, the pixel parameters of each light emitting unit can be adjusted from the global angle, so that the displayed image area achieves the preset display effect, and the display effect of the image is improved.

Embodiment III:

the embodiment of the invention also provides another display control method, which is realized on the basis of the method of the embodiment; the method mainly describes a specific implementation process of adjusting pixel parameters of a light emitting unit of a target display device according to pixel arrangement information of the light emitting unit, wherein the pixel parameters comprise brightness of pixels; specifically, as shown in fig. 3, the method includes the following steps:

Step S302, obtaining an image to be processed and pixel arrangement information of a light emitting unit of a target display device; the target display device is used for displaying at least one part of image area of the image to be processed; the light emitting unit in the target display device has a plurality of pixel arrangements.

Step S304, determining an adjustment mode of at least two pixel parameters according to pixel arrangement information of the light emitting unit; the adjustment modes of the at least two pixel parameters comprise a first adjustment mode and a second adjustment mode.

The above adjustment method can be understood as an adjustment amplitude of the pixel parameter, or an adjustment amplitude combination, or the like. For example, when the pixel parameter is luminance, the adjustment may be 10 increases in luminance for the light emitting unit a, 20 decreases in luminance for the light emitting unit B, and so on. For another example, taking a light emitting unit including RGB pixels as an example, for the light emitting unit a, the adjustment may be an increase of 10 in R pixel brightness, an increase of 30 in g and B pixel brightness, and for the light emitting unit B, the adjustment may be an increase of 30 in R pixel brightness, a decrease of 10 in g and B pixel brightness, and so on. The adjustment manners of at least two pixel parameters are determined according to the pixel arrangement information of the light emitting units, and it may be understood that at least one light emitting unit in the target display device is different from other light emitting units, and the adjustment manner corresponding to the at least one light emitting unit may be understood as the first adjustment manner, and the adjustment manner of some or all of the other light emitting units may be understood as the second adjustment manner. In practical implementation, according to different pixel arrangement information of the light emitting units, two or more adjustment modes of pixel parameters may be included, for example, the target display device further includes light emitting units adjusted by a third adjustment mode, a fourth adjustment mode, and the like in addition to the light emitting units adjusted by the first adjustment mode and the second adjustment mode, and those skilled in the art may adjust the plurality of light emitting units in the target display device in different adjustment modes according to application situations, which will not be described herein.

Step S306, adopting a first adjustment mode to adjust pixel parameters of at least one light-emitting unit of the target display device; and adjusting pixel parameters of part or all of the light emitting units except at least one light emitting unit of the target display device in a second adjustment mode.

Since the pixel arrangement modes of the light emitting units in the target display device are different and have no regularity, for example, the relative positions and distances between the initial brightness centers of the light emitting units and the target brightness centers are different, in order to make the target brightness centers of the light emitting units meet the target display parameters, all pixels of the light emitting units in the target display device cannot be adjusted in the same adjustment mode, and the pixel parameters need to be adjusted in a pixel adjustment mode matched with the light emitting units according to the relative positions, distances between the initial brightness centers of the light emitting units and the target brightness centers, and the like. For example, if the two pixel parameter adjustment methods, i.e., the first adjustment method and the second adjustment method, are determined according to the pixel arrangement information of the light emitting units, the pixel parameter of at least one light emitting unit in the target display device is adjusted by using the first adjustment method, and the pixel parameter of all or part of the light emitting units except for the at least one light emitting unit in the target display device is adjusted by using the second adjustment method.

Step S308, at least a part of the image area is displayed by the adjusted target display device.

The above display control method describes in detail a specific process of adjusting pixel parameters of a light emitting unit of a target display device according to pixel arrangement information of the light emitting unit, and determines an adjustment mode including at least two pixel parameters according to the pixel arrangement information of the light emitting unit; the adjustment modes of the at least two pixel parameters comprise a first adjustment mode and a second adjustment mode; adjusting pixel parameters of at least one light emitting unit of the target display device in a first adjustment mode; and adjusting pixel parameters of part or all of the light emitting units except at least one light emitting unit of the target display device in a second adjustment mode. In this mode, the pixel parameters of the light emitting unit are adjusted based on the pixel arrangement information of the light emitting unit of the target display device; even if the light emitting units in the target display device have various pixel arrangements, the pixel parameters of each light emitting unit can be adjusted from the global angle, so that the displayed image area achieves the preset display effect, and the display effect of the image is improved.

Embodiment four:

The embodiment of the invention also provides another display control method, which is realized on the basis of the method of the embodiment; the method mainly describes a specific implementation process of adjusting pixel parameters of a light emitting unit of a target display device according to pixel arrangement information of the light emitting unit, wherein the pixel parameters comprise brightness of pixels; specifically, as shown in fig. 4, the method includes the following steps:

step S402, obtaining an image to be processed and pixel arrangement information of a light emitting unit of a target display device; the target display device is used for displaying at least one part of image area of the image to be processed; the light emitting unit in the target display device has a plurality of pixel arrangements.

Step S404, for each light emitting unit, determining an initial brightness center of an image area corresponding to the light emitting unit in at least a part of the image area displayed by the light emitting unit according to pixel arrangement information of the light emitting unit.

The initial luminance center described above may be understood as an initial position of the displayed luminance center for each light emitting unit before the luminance of the pixel of the light emitting unit is adjusted. In practical implementation, considering that different light emitting units generally have different pixel arrangement information, such as different pixel arrangement modes, when determining an initial brightness center of an image area corresponding to a light emitting unit in at least a part of image areas displayed by the light emitting unit, determination needs to be performed for each light emitting unit separately.

Step S406, adjusting the brightness of the pixels of the light emitting units of the target display device according to the initial brightness center corresponding to each light emitting unit and the target display parameter.

The target display parameters may make the brightness of at least a part of the image area for displaying the image to be processed uniform, or may make the brightness or color of at least a part of the image area for displaying the image to be processed change according to a preset rule, etc. In one embodiment, the target display parameters may include one or more of the following:

Parameter one: the target luminance center of each light emitting unit is the same distance as the target luminance center of each light emitting unit in the preset direction adjacent to the light emitting unit. In the display technology, the human eye perceives the luminance center most strongly, and the light emitting unit includes RGB pixels, and the RGB pixels are arranged in a triangle, so that the luminance center may be shifted and generally closer to the G pixel because the sensitivity of the human eye to the G pixel is relatively higher even though the luminance values of the RGB pixels are the same. For example, the human eye has sensitivity to three pixels, wherein the ratio of the sensitivity to the three pixels is 70% for the G pixel, 20% for the R pixel, and 10% for the B pixel, and if the brightness is different, the brightness center usually needs to be recalculated; the brightness center of the light emitting unit can be calculated by adopting the prior art, and is not described herein. The target luminance center may be understood as a position of a luminance center that can satisfy the target display parameter, for example, still taking the light emitting unit including RGB pixels, and the RGB pixels are arranged in a triangle as an example, and the target luminance center may be a center of the RGB pixels arranged in a triangle, or any position of a triangle area formed by the RGB pixels, and the like; the predetermined direction may be an upper, lower, left or right side of the light emitting unit, etc.

And (2) parameters II: when it is necessary to achieve a target display parameter that makes the luminance of at least a part of an image area where an image to be processed is displayed uniform, it is generally necessary to uniformly distribute the luminance center of each light emitting unit, and this can be achieved by making the target luminance center of each light emitting unit the same distance from the target luminance center of each light emitting unit in a preset direction adjacent to the light emitting unit. The uniform distribution of the target luminance center of each light emitting unit in the designated display area is equivalent to the uniform distribution of the target luminance center, which can also be understood as the equal distance of the target luminance centers of the adjacent light emitting units in the horizontal and vertical directions.

And (3) parameters III: the target brightness center of each light emitting unit is positioned on the same horizontal line with the target brightness center of the light emitting unit in the same row to which the light emitting unit belongs. In order to make the brightness of at least a part of the image area of the image to be processed more uniform, it is also generally possible to center the target brightness of each light emitting unit in the same row on the same horizontal line for each light emitting unit in the designated display area, and it is generally required that the horizontal line be sufficiently straight.

Parameter four: the target brightness center of each light emitting unit is positioned on the same vertical line with the target brightness center of the light emitting unit in the same column to which the light emitting unit belongs. In order to make the brightness of at least a part of the image area of the image to be processed more uniform, it is also generally possible to center the target brightness of each light emitting unit in the same column on the same vertical line for each column of light emitting units in the designated display area, and it is generally required that the vertical line be sufficiently straight.

In an embodiment, the target display parameters may also include display parameters of the reference image. The reference image can be stored locally in advance or can be obtained from a network; the reference image may be an original image or an image processed based on the original image. The display parameter of the reference image may be a parameter such as a pixel value, brightness, or color of the reference image, or may be a parameter obtained by processing the reference image based on the pixel value, brightness, or color. The brightness of the pixels of the light emitting unit of the target display device is adjusted based on the display parameters of the reference image, so that the display effect of the image to be processed displayed by the target display device can be similar to that of the reference image. Further, in order to make the display effect of the image to be processed displayed by the target display device universal, the display parameters of the reference image may be obtained based on a large number of original images, for example, the pixel values, brightness, colors, etc. of a large number of original images are calculated, the expected values, average values, etc. are calculated, and the calculated results are used as the display parameters of the reference image, so that a plurality of images to be processed are displayed based on the display parameters of the reference image, and the preset display effect can be obtained.

In actual implementation, the brightness of the display image can be made uniform by a rendering algorithm, which may be an SPR (Sub Pixel Rendering, sub-pixel rendering) algorithm or other rendering algorithms; the rendering algorithm module may also be referred to as a controller, where the task of the controller is to implement one or more of the target display parameters described above, and as shown in a flowchart of one rendering algorithm module shown in fig. 5, after the image to be processed is acquired, the image to be processed is sent to the controller, and the image to be processed is rendered by the controller, so as to obtain a rendered image finally.

In actual implementation, this step S406 may be specifically implemented by the following steps 30 to 31:

step 30, determining a target brightness center of each light-emitting unit according to the target display parameters; in actual implementation, this step 30 may be implemented specifically by the following steps 301 to 302:

step 301, for each light emitting unit, establishing the following constraint equation according to the target display parameter, wherein the constraint equation may be understood as an equation formed by some conditions that must be satisfied in order to reach the target display parameter:

The target brightness center of the light emitting unit is the same as the distance between the target brightness center of each light emitting unit in the preset direction adjacent to the light emitting unit; in actual implementation, for the current light-emitting unit, the distance between the target brightness center of the current light-emitting unit and the target brightness center of the light-emitting unit adjacent to the left side, the target brightness center of the light-emitting unit adjacent to the right side, or the target brightness centers of the two light-emitting units adjacent to the left side and the right side in the same row can be calculated first; calculating the distances between the target brightness center of the current light-emitting unit and the target brightness center of the light-emitting unit adjacent to the upper part, the target brightness center of the light-emitting unit adjacent to the lower part or the target brightness centers of the two light-emitting units adjacent to each other; the constraint condition may be understood that, for the current light emitting unit, the target luminance center of the light emitting unit is the same distance from the target luminance center of each light emitting unit above, below, left or right, etc., adjacent to the light emitting unit.

And the sum of absolute values of differences between the ordinate of the target brightness center of each light-emitting unit in the same row to which the light-emitting unit belongs and the preset standard ordinate is zero; in actual implementation, a specified light-emitting unit can be selected from the rows to which the current light-emitting unit belongs according to a preset rule, and the ordinate of the target brightness center of the specified light-emitting unit can be understood as a preset standard ordinate; for example, for each row of light emitting units in the designated display area, the first light emitting unit of the left number in the row to which the current light emitting unit belongs may be selected as the designated light emitting unit; or if the designated display area comprises a plurality of rows of light emitting units, selecting a first light emitting unit with the left number from the first row of light emitting units as a designated light emitting unit, selecting a second light emitting unit with the left number from the second row of light emitting units as a designated light emitting unit, and so on until the corresponding designated light emitting unit is selected from the plurality of rows of light emitting units; specifically, a rule for selecting a specified light emitting unit can be determined according to actual requirements.

The constraint condition can be understood that, after a specified light-emitting unit is selected from the row to which the current light-emitting unit belongs, the absolute value of the difference between the ordinate of the target brightness center of each light-emitting unit in the row and the preset standard ordinate is calculated, so that the sum of the absolute values of the calculated differences is zero; it is also understood that, based on the target luminance center of the selected specified light emitting unit, a horizontal line is drawn, and a lateral offset loss of each light emitting unit with respect to the horizontal line in the ordinate direction is calculated based on the ordinate of the target luminance center of each light emitting unit in the row to which the horizontal line belongs, the lateral offset loss also corresponds to the lateral offset distance, and the sum of the calculated lateral offset distances is zero.

And the sum of absolute values of differences between the abscissa of the target brightness center of each light-emitting unit in the same row to which the light-emitting unit belongs and the preset standard abscissa is zero; in actual implementation, a designated light-emitting unit can be selected from columns to which the current light-emitting unit belongs according to a preset rule, and the abscissa of the target brightness center of the designated light-emitting unit can be understood as a preset standard abscissa; for example, for each column of light emitting units in the designated display area, the first light emitting unit from above in the column to which the current light emitting unit belongs may be selected as the designated light emitting unit; or if the specified display area comprises a plurality of columns of light-emitting units, selecting a first light-emitting unit from the upper part from the first column of light-emitting units from the left part as a specified light-emitting unit, selecting a second light-emitting unit from the upper part from the second column of light-emitting units from the left part as a specified light-emitting unit, and so on until the corresponding specified light-emitting unit is selected from the plurality of columns of light-emitting units; specifically, a rule for selecting a specified light emitting unit can be determined according to actual requirements.

The constraint condition may be understood that, after a specified light-emitting unit is selected from a column to which the current light-emitting unit belongs, the absolute value of the difference between the abscissa of the target brightness center of each light-emitting unit in the column and the preset standard abscissa is calculated, so that the sum of the calculated absolute values of the differences is zero; it is also understood that, based on the target luminance center of the selected specified light emitting unit, a vertical line is drawn, and based on the abscissa of the target luminance center of each light emitting unit in the column, the longitudinal offset loss of each light emitting unit in the abscissa direction with respect to the vertical line is calculated, which also corresponds to the longitudinal offset distance, and the sum of the calculated longitudinal offset distances is zero.

Step 302, adjusting the initial brightness center of each light emitting unit based on the constraint equation to obtain the target brightness center of each light emitting unit.

Adjusting an initial brightness center of each light emitting unit based on the constraint equation, so that the adjusted initial brightness center of each light emitting unit in the same row is on the same horizontal line, the adjusted initial brightness center of each light emitting unit in the same column is on the same vertical line, and for the current light emitting unit, the distance between the adjusted initial brightness center of the light emitting unit and the adjusted target brightness center of each light emitting unit adjacent to the light emitting unit above, below, left or right is the same; for each light emitting unit, the adjusted initial luminance center of that light emitting unit is determined as the target luminance center.

Step 31, adjusting the brightness of the pixel of each light emitting unit in the target display device according to the target brightness center of each light emitting unit and the initial brightness center corresponding to each light emitting unit. Specifically, this step 31 may be specifically implemented by the following steps 311 to 312:

Step 311, for each light emitting unit in the target display device, determining a brightness adjustment coefficient of each pixel in the light emitting unit according to the target brightness center and the initial brightness center of the light emitting unit.

The above-mentioned brightness adjustment coefficient may be understood as a proportionality coefficient for adjusting brightness; for each light emitting unit in the target display device, determining a brightness adjustment coefficient of each pixel in the light emitting unit according to the coordinate of the target brightness center of the light emitting unit and the coordinate of the initial brightness center; for example, taking an example that a light emitting unit includes RGB pixels, according to a target luminance center and an initial luminance center of a specific light emitting unit, the determined luminance adjustment coefficients of an R pixel, a G pixel, and a B pixel of the light emitting unit are 1.5, 0.8, and 1, respectively; in actual implementation, the brightness adjustment coefficients of the pixels of each light emitting unit are generally required to be calculated respectively, and the current light emitting unit can be selected according to a preset manner, for example, in units of rows, that is, after the brightness adjustment coefficients of the pixels of each light emitting unit in a certain row are determined, the brightness adjustment coefficients of the pixels of each light emitting unit in the next row are continuously determined; or selecting the current light emitting unit in units of columns, that is, after determining the brightness adjustment coefficients of the respective pixels of each light emitting unit in a certain column, continuing to determine the brightness adjustment coefficients of the respective pixels of each light emitting unit in the next column.

Step 312, according to the brightness adjustment coefficients of the pixels, the initial brightness of the pixels in the light emitting unit is adjusted to obtain the final brightness of the pixels in the light emitting unit.

The initial luminance may be understood as a luminance value of each pixel for each light emitting unit before the luminance of each pixel in the light emitting unit is adjusted; the final brightness may be understood as a brightness value of each pixel after the brightness of each pixel in each light emitting unit is adjusted; the brightness value of the pixel is usually between 0 and 255, the brightness near 255 is higher, the brightness near 0 is lower, and the rest part belongs to the middle tone; in actual implementation, the brightness adjustment coefficient of each pixel can be multiplied by the initial brightness of each pixel in the light-emitting unit correspondingly to obtain the final brightness of each pixel in the light-emitting unit; for example, taking an example that a light emitting unit includes RGB pixels, initial luminance values of R pixels, G pixels and B pixels in a specific light emitting unit are respectively 100, 150 and 200, and luminance adjustment coefficients of R pixels, G pixels and B pixels of the light emitting unit determined by the above steps are respectively 1.5, 0.8 and 1, then final luminance values of R pixels, G pixels and B pixels in the light emitting unit are respectively 100×1.5=150, 150×0.8=120 and 200×1=200.

When the arrangement modes of the pixels in the light emitting units are different and have no regularity, taking the light emitting units including three kinds of pixels of RGB as an example, the distribution of the three kinds of pixels of RGB is equal to be non-uniform in the whole world, at this time, if the brightness of the three kinds of pixels of RGB in each light emitting unit is consistent, the phenomenon of non-uniform brightness of at least a part of the image area for displaying the image to be processed can occur, and the rendering method can lead the display brightness of at least a part of the image area for displaying the image to be processed to be uniform.

In actual implementation, each pixel of the light emitting unit of the target display device generally includes positive and negative electrodes, and the positive and negative electrodes are connected to an external driving circuit through a connection circuit, and the brightness of the corresponding pixel can be adjusted by controlling the magnitude of current or voltage output by the driving circuit.

In step S408, at least a part of the image area is displayed by the adjusted target display device.

The above display control method describes in detail a specific process of adjusting pixel parameters of a light emitting unit of a target display device according to pixel arrangement information of the light emitting unit, and for each light emitting unit, determining an initial brightness center when the light emitting unit displays at least a part of image areas corresponding to the light emitting unit according to the pixel arrangement information of the light emitting unit; and adjusting the brightness of the pixels of the light emitting units of the target display device according to the initial brightness center corresponding to each light emitting unit and the target display parameters. In this aspect, the brightness of each pixel in each light emitting unit is adjusted based on the pixel arrangement information of each light emitting unit in the designated display area of the target display device; even if the light emitting units in the target display device have various pixel arrangements, the pixel brightness of each light emitting unit can be adjusted from the global angle, so that the displayed image area achieves the preset display effect, and the display effect of the image is improved.

To further understand the above embodiment, an algorithm flow chart of a controller is provided below, as shown in fig. 6, first, calculating an initial luminance center of each light emitting unit in the target display device, for each light emitting unit, calculating a distance between the initial luminance center of the light emitting unit and an initial luminance center of an adjacent light emitting unit, a lateral offset loss of the initial luminance center of each light emitting unit of the same row to which the light emitting unit belongs, and a longitudinal offset loss of the initial luminance center of each light emitting unit of the same column to which the light emitting unit belongs, and adjusting the initial luminance center of each light emitting unit according to three constraint conditions in constraint equations in the above embodiment to obtain a target luminance center of each light emitting unit; for each light emitting unit, determining a proportionality coefficient of each pixel in the light emitting unit according to a target brightness center and an initial brightness center of the light emitting unit, wherein the proportionality coefficient is equivalent to the brightness adjustment coefficient, and can be understood as applying constraint on the proportionality coefficient through the constraint condition so as to obtain the proportionality coefficient of each pixel; according to the proportionality coefficient of each pixel, the initial brightness of each pixel is adjusted to obtain the final brightness of each pixel of the light-emitting unit, or the initial brightness of each pixel in the light-emitting unit is adjusted by a controller to obtain the final brightness of each pixel in each light-emitting unit of the rendered image, so that the rendering is completed; considering that the pixel arrangement of each light emitting unit in the designated display area has non-repeatability, the initial brightness of the pixels in each light emitting unit needs to be calculated and adjusted respectively to complete the global rendering of the designated display area.

Fifth embodiment:

The embodiment of the invention also provides another display control method, which is realized on the basis of the method of the embodiment; the method focuses on describing a specific implementation process of acquiring an image to be processed, as shown in fig. 7, and includes the following steps:

Step S702, acquiring an image to be processed through an under-screen camera device; wherein the under-screen camera device is arranged on the backlight surface of the target display device; pixels in the target display device are non-repeatedly arranged; or acquiring an image to be processed from a local storage area of the current equipment; or acquiring the image to be processed from the network connected with the current device.

The under-screen camera device can be an under-screen camera in electronic equipment with an under-screen camera such as a mobile phone or an iPad, and the under-screen camera device is used for collecting images to be processed; the backlight surface can be understood as the opposite surface of the target display device, which can also be referred to as the back surface of the target display device when facing the display screen of the terminal such as a mobile phone or an iPad; the under-screen camera device is usually arranged on the backlight surface of a display screen of a terminal such as a mobile phone or an iPad; in order to make the image display effect, light transmittance, or diffraction fringes distributed as uniformly as possible, the pixels in each light emitting unit in the designated display area of the target display device are typically arranged non-repeatedly and generally do not have any regularity, for example, RGB pixels included in the light emitting units may be arranged in a lateral order, RGB pixels in one light emitting unit may be arranged in a longitudinal order, or in a triangular order, or the like.

As can be seen from the foregoing embodiments, the target display device may be the entire display screen of an electronic device with an under-screen camera, such as a mobile phone or an iPad, or may be a small display screen corresponding to the under-screen camera in the entire display screen of the electronic device with the under-screen camera, such as the mobile phone or the iPad; when the target display device is the whole display screen of the mobile phone or the iPad and other terminals, pixels in a designated display area corresponding to the under-screen camera are arranged non-repeatedly, and image rendering is carried out by adopting a rendering mode in the following steps; in the display screen, pixels in other areas except a designated display area can be repeatedly arranged in a mode in the prior art, and the image rendering process of the area can be performed by adopting the prior art, namely, a single light-emitting unit is subjected to rendering, and each light-emitting unit in the area is suitable for the same rendering process; when the target display device is a small display screen corresponding to the under-screen camera in the whole display screen of the mobile phone or the iPad and other terminals, pixels in the target display device are arranged non-repeatedly, and the display control of the image is carried out by adopting the following steps.

In actual implementation, an initial image is generally collected by an under-screen camera device, and is preprocessed, wherein the preprocessing can be understood as removing interference information such as diffraction fringes and the like in the initial image; because the under-screen camera device collects the initial image through the light holes in the target display device, the initial image usually carries some optical interference information, such as diffraction fringes and the like, and the optical interference information can be removed through an image restoration algorithm, so that the preprocessed initial image is close to the non-screen image.

And extracting an image area to be displayed by the target display device from the preprocessed initial image, and determining the image area to be displayed by the target display device as an image to be processed.

When the target display device is the whole display screen of the mobile phone or the terminal such as the iPad, the whole preprocessed initial image can be understood as the image area required to be displayed by the target display device, and can also be understood as the image to be processed.

When the target display device is a small display screen corresponding to the under-screen camera in the whole display screen of the mobile phone or the iPad and other terminals, extracting a small part of image area corresponding to the target display device from the preprocessed initial image, wherein the small part of image area corresponds to the image to be processed.

In actual implementation, the image to be processed can also be obtained from a local storage area of the current equipment; or acquiring an image to be processed from a network connected with the current equipment; for example, taking the current device as a mobile phone, the image to be processed can be obtained from an album locally stored in the mobile phone, or the image to be processed can be downloaded from a network through connecting the mobile phone to the network.

Step S704, obtaining pixel arrangement information of a light emitting unit of a target display device; the target display device is used for displaying at least one part of image area of the image to be processed; the light emitting unit in the target display device has a plurality of pixel arrangements.

Step S706, adjusting the pixel parameters of the light emitting unit of the target display device according to the pixel arrangement information of the light emitting unit.

Step S708, displaying at least a part of the image area by the adjusted target display device. The display control method describes the specific process of acquiring the image to be processed in detail, and the image to be processed is acquired through a preset under-screen camera device; or acquiring an image to be processed from a local storage area of the current equipment; or acquiring the image to be processed from the network connected with the current device. In this mode, the pixel parameters of the light emitting unit are adjusted based on the pixel arrangement information of the light emitting unit of the target display device; even if the light emitting units in the target display device have various pixel arrangements, the pixel parameters of each light emitting unit can be adjusted from the global angle, so that the displayed image area achieves the preset display effect, and the display effect of the image is improved.
