[0040] The features and exemplary embodiments of various aspects of the present application will be described in detail below. For the purpose of making the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0041] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.

[0042] With the development of display technology, people's requirements for display devices have gradually increased. In order to achieve a higher screen-to-body ratio, the full-screen display device has emerged as the times require. The so-called full screen means that the functional area can not only implement functions such as under-screen camera or under-screen touch, but also display images.

[0043] In a full-screen display device, there are usually multiple different display areas. Exemplarily, the full-screen display device includes a normal display area and a photosensitive area. Both the normal display area and the photosensitive area can achieve a display effect. At the same time, an under-screen camera or a fingerprint recognition module can be arranged at the photosensitive area to implement a photosensitive function.

[0044] In order to ensure the display effect of the display device, it is necessary to perform parameter debugging processes such as gamma debugging on the display device before leaving the factory. Different from conventional display devices, the full-screen display device needs to perform parameter debugging processes such as gamma debugging on different display areas separately. In this process, it is necessary to manually intervene to adjust the relative position between the display device and the optical acquisition device, which will lead to an increase in the production cycle time of the full-screen display device, and at the same time, it is impossible to ensure the accuracy and precision of the adjustment, which is not conducive to the large-scale production process.

[0045] To solve the above problems, an adjustment device for a display module is provided in an embodiment of the present application. The adjustment device for a display module provided in an embodiment of the present application is used to execute the adjustment method for a display module provided in any embodiment of the present application. Please refer to Figure 1 and Figure 2 , the display module includes a first display area 11 and a second display area 12. The adjustment device includes an image acquisition module 21 and a position adjustment module 22.

[0046] The image acquisition module 21 is configured to acquire at least a part of the display screen of the display module. The position adjustment module 22 is configured to adjust the position of the display module and / or the image acquisition module 21 according to the image acquired by the image acquisition module 21 when different images are displayed in the first display area 11 and the second display area 12, so that the image acquisition module 21 and the display module are in a preset relative position.

[0047] The display module includes a first display area 11 and a second display area 12. During the use of the display module, both the first display area 11 and the second display area 12 can emit light to present corresponding display images. Before the display module leaves the factory, it is necessary to separately debug the parameters of the first display area 11 and the second display area 12, such as gamma debugging, etc., to improve the display accuracy of the two display areas. The present application embodiment does not limit the positional relationship, quantity, size, shape, etc. between the first display area 11 and the second display area 12. Exemplarily, the second display area 12 can be disposed around the outer peripheral side of the first display area 11. The first display area 11 can be circular or rectangular, etc. The second display area 12 can be circular or rectangular, etc. The size of the first display area 11 can be less than or equal to the size of the second display area 12. The first display area 11 and the second display area 12 can be adjacent and closely arranged. The acquisition area of the image acquisition module 21 can be less than or equal to the size of the first display area 11.

[0048] Optionally, the image acquisition module 21 and the display module being in a preset relative position may include: the image acquisition module 21 is opposite to the first display area 11 in a direction perpendicular to the display surface of the display module, that is, the image acquisition module 21 and the first display area 11 are in a first preset relative position.

[0049] Optionally, the image acquisition module 21 and the display module being in a preset relative position may include: the image acquisition module 21 is opposite to the second display area 12 in a direction perpendicular to the display surface of the display module, that is, the image acquisition module 21 and the second display area 12 are in a second preset relative position.

[0050] Exemplarily, the display characteristics of the first display area 11 and the second display area 12 may be different, and it is necessary to separately debug the parameters of the first display area 11 and the second display area 12, such as gamma debugging, etc., instead of unified debugging. Exemplarily, there are differences in the pixel structures in the first display area 11 and the second display area 12 (such as differences in pixel density, scan line length, pixel driving circuit structure, etc.), resulting in differences in the display characteristics of the first display area 11 and the second display area 12.

[0051] The image acquisition module 21 is used to acquire image information within a local area in the display module. Exemplarily, the image acquisition module 21 includes an optical acquisition module. For example, the image acquisition module 21 may include a charge coupled device (CCD). Before the display module leaves the factory, parameter debugging processes need to be performed on the first display area 11 and the second display area 12 respectively. For example, it may be gamma debugging, etc. During this process, the image acquisition module 21 can be used to acquire the images displayed in the first display area 11 and the second display area 12 respectively to obtain corresponding image information. In order to ensure that the image acquisition module 21 can accurately acquire the image information of the first display area 11 or the second display area 12 in the display module, the present application embodiment adds a position adjustment module 22, and through the mutual cooperation between the position adjustment module 22 and the image acquisition module 21, the perfect locking of the position of the first display area 11 is achieved, ensuring the precise positioning of the display module and the image acquisition module 21.

[0052] Specifically, the display module can control to display the required images. When different image contents are displayed in the first display area 11 and the second display area 12, there are differences in the corresponding image information of the first display area 11 and the second display area 12, so as to facilitate the identification of the boundary or junction position between the first display area 11 and the second display area 12, and then accurately identify the positions of the first display area 11 and the second display area 12, and then adjust to the corresponding positions for subsequent parameter debugging processes such as gamma debugging. Exemplarily, at this time, if the image information acquired by the image acquisition module 21 is the same as the image information presented in the first display area 11 of the display module, it means that the position of the image acquisition module 21 relative to the first display area 11 is accurate, and the two are in a first preset relative position.

[0053] Exemplarily, if the image information acquired by the image acquisition module 21 is different from the image information presented in the first display area 11 of the display module, it means that there is a deviation in the relative position between the image acquisition module 21 and the first display area 11. Then the position adjustment module 22 adjusts the position of the image acquisition module 21 and / or the display module until the image information acquired by the image acquisition module 21 is the same as the image information presented in the first display area 11. At this time, it means that the position of the image acquisition module 21 relative to the first display area 11 is accurate, and the two are in a first preset relative position.

[0054] Please refer to Figure 3 Similarly, the cooperation between the image acquisition module 21 and the position adjustment module 22 can be used to adjust the position of the image acquisition module 21 and / or the display module so that the image acquisition module 21 and the second display area 12 are in a second preset relative position.

[0055] It should be noted that Figure 2 and Figure 3Taking the example that the position adjustment module 22 drives the display module to move, so as to adjust the positional relationship between the display module and the image acquisition module 21 for illustration. Alternatively, the position adjustment module 22 can also adjust the positional relationship between the two by driving the image acquisition module 21 to move.

[0056] In the embodiment of the present application, through the mutual cooperation between the image acquisition module 21 and the position adjustment module 22, the automatic adjustment of the relative position between the display module and the image acquisition module 21 is realized, avoiding manual intervention during the adjustment process, thereby improving the accuracy and reliability of the adjustment process while improving the efficiency.

[0057] In some embodiments, referring to Figure 4 , the adjustment device further includes a parameter debugging module 23, and the parameter debugging module 23 is used to perform parameter debugging on the first display area 11 when the image acquisition module 21 and the first display area 11 are in a first preset relative position.

[0058] In some embodiments, the adjustment device further includes a parameter debugging module 23, and the parameter debugging module 23 is used to perform parameter debugging on the second display area 12 when the image acquisition module 21 and the second display area 12 are in a second preset relative position.

[0059] Among them, the first preset relative position is different from the second preset relative position, so as to separately perform parameter debugging on the first display area 11 and the second display area 12.

[0060] In addition to being able to cooperate with the position adjustment module 22 to change the positional relationship between the display module and the image acquisition module 21, the image acquisition module 21 can also cooperate with the parameter debugging module 23 to realize the parameter debugging of the display module.

[0061] Optionally, the parameter debugging module 23 is used to perform parameter debugging on the first display area 11 according to the display screen of the first display area 11 collected by the image acquisition module 21 when the image acquisition module 21 and the first display area 11 are in a first preset relative position.

[0062] Optionally, the parameter debugging module 23 is used to perform parameter debugging on the second display area 12 according to the display screen of the second display area 12 collected by the image acquisition module 21 when the image acquisition module 21 and the second display area 12 are in a second preset relative position. Optionally, the parameter debugging module 23 includes a gamma debugging module. Optionally, the parameter debugging includes gamma debugging.

[0063] Specifically, when the image acquisition module 21 is in a first preset relative position with respect to the first display area 11, the image acquisition module 21 can acquire the image information within the first display area 11. At this time, the gamma debugging module can cooperate with the image acquisition module 21 to perform gamma debugging on the first display area 11.

[0064] Similarly, when the image acquisition module 21 is in a second preset relative position with respect to the second display area 12, the image acquisition module 21 can acquire the image information within the second display area 12. At this time, the gamma debugging module can cooperate with the image acquisition module 21 to perform gamma debugging on the second display area 12.

[0065] Compared with the solution where different image acquisition modules 21 are used in the two processes of display module position adjustment and display module parameter debugging, in the embodiment of the present application, the same image acquisition module 21 is used in the two processes of display module position adjustment and display module parameter debugging. The image acquisition module 21 in the embodiment of the present application can play a specific role in the two processes of display module position adjustment and display module parameter debugging, without the need to additionally add other devices, thereby simplifying the overall structure of the adjustment device.

[0066] In some embodiments, the gamma debugging module is used to perform gamma debugging on the first display area 11 according to the display screen of the first display area 11 acquired by the image acquisition module 21 when the image acquisition module 21 is in a first preset relative position with respect to the first display area 11.

[0067] In some embodiments, the gamma debugging module is used to perform gamma debugging on the second display area 12 according to the display screen of the second display area 12 acquired by the image acquisition module 21 when the image acquisition module 21 is in a second preset relative position with respect to the second display area 12.

[0068] Exemplarily, during the process of performing gamma debugging on the first display area 11, the image acquisition module 21 continuously acquires and measures the display screen of the first display area 11 to obtain the optical parameters therein. Then the gamma debugging module can correct the gamma voltage of the first display area 11 as needed until the brightness and gray scale presented by the first display area 11 can conform to the target gamma curve.

[0069] Similarly, during the process of performing gamma debugging on the second display area 12, the image acquisition module 21 continuously acquires and measures the display screen of the second display area 12 to obtain the optical parameters therein.

[0070] Then the gamma debugging module can correct the gamma voltage of the second display area 12 as needed until the brightness and gray scale presented by the second display area 12 can conform to the target gamma curve.

[0071] Optionally, the gamma curves adopted by the first display area 11 and the second display area 12 may be the same or different.

[0072] In some embodiments, referring to Figure 4 , the adjustment device further includes a programming module 24 for programming the data obtained after parameter debugging by the parameter debugging module into the display module.

[0073] In some embodiments, the adjustment device further includes a gamma programming module 24 for programming the gamma data obtained after gamma debugging by the gamma debugging module into the display module.

[0074] The programming module 24 is used to program the gamma data corresponding to the first display area 11 and the second display area 12 after debugging into the memory of the display module, so that the display module can respectively obtain the mapping relationship between the target display parameters of the first display area 11 and the second display area 12 and the corresponding data signal parameters, so that the first display area 11 and the second display area 12 can be displayed according to the accurate data signal parameters at different gray levels.

[0075] In some embodiments, when the position adjustment module 22 is used to display a black screen in the first display area 11 and the brightness of the display screen in the second display area 12 is greater than the brightness of the black screen, if the brightness of the screen collected by the image acquisition module 21 is less than or equal to the preset brightness value, the position of the display module and / or the image acquisition module 21 is stopped from being adjusted, so that the image acquisition module 21 and the first display area 11 are in a first preset relative position.

[0076] In some embodiments, when the position adjustment module 22 is used to display a black screen in the first display area 11 and the brightness of the display screen in the second display area 12 is greater than the brightness of the black screen, if the brightness of the screen collected by the image acquisition module 21 is greater than the preset value, the position of the display module and / or the image acquisition module 21 is adjusted until the brightness of the screen collected by the image acquisition module 21 is less than or equal to the preset brightness value, and then the adjustment of the position of the display module and / or the image acquisition module 21 is stopped, so that the image acquisition module 21 and the first display area 11 are in a first preset relative position.

[0077] A black screen is displayed in the first display area 11, and a screen with a higher brightness than the black screen is displayed in the second display area 12. For example, the second display area 12 can be made to display the screen with the maximum brightness it can reach. Exemplarily, if the brightness (such as the average brightness or the maximum brightness, etc.) corresponding to the screen collected by the image acquisition module 21 is not greater than the preset brightness value, it means that the screen collected by the image acquisition module 21 is all black, then the image acquisition module 21 and the first display area 11 are opposite in the direction perpendicular to the display surface of the display module, that is, the image acquisition module 21 and the first display area 11 are in a first preset relative position.

[0078] Exemplarily, when the brightness corresponding to the picture captured by the image capture module 21 (such as the average brightness or the maximum brightness, etc.) is greater than the preset brightness value, it indicates that the picture captured by the image capture module 21 is not completely black, and at least part of the picture in the second display area 12 is included therein. At this time, it is necessary to adjust the positions of the display module and / or the image capture module 21 with the aid of the position adjustment module 22. Optionally, the preset brightness value is 0.001 nit.

[0079] Optionally, the capture area of the image capture module 21 may be less than or equal to the size of the first display area 11. Optionally, the capture area of the image capture module 21 may be greater than the size of the first display area 11. When making a position adjustment to make the image capture module 21 and the first display area 11 in a first preset relative position, a light-shielding layer may be provided on the periphery of the first display area 11, and the light-shielding layer covers a partial area of the second display area 12 outside the first display area 11, and the area formed by combining the light-shielding layer and the first display area 11 has the same size as the capture area of the image capture module 21. Optionally, the center of the area formed by combining the light-shielding layer and the first display area 11 coincides with the center of the first display area 11. Optionally, when performing parameter debugging on the first display area 11 subsequently, the light-shielding layer may be removed.

[0080] In addition, there are various ways to make the first display area 11 display a black picture, and the embodiments of the present application do not limit this.

[0081] In some alternative embodiments, the display module sends the gamma voltage corresponding to the minimum driving current to the first display area 11. The display module includes a pixel circuit. When the driving current is the smallest, the brightness of the first display area 11 is the lowest, and at this time, the first display area 11 can display a completely black picture.

[0082] It should be noted that when the pixel circuit in the display module uses a PMOS transistor as the driving transistor, the gamma voltage corresponding to the first display area 11 can be adjusted to the maximum, and the data voltage generated by this gamma voltage is also the maximum, so that the current in the pixel circuit is zero. When the pixel circuit in the display module uses an NMOS transistor as the driving transistor, the gamma voltage corresponding to the first display area 11 can be adjusted to the minimum, and the data voltage generated by this gamma voltage is also the minimum, so that the current in the pixel circuit is zero.

[0083] In some alternative embodiments, the display module can also send a completely black image to the first display area 11 for display, so as to make the first display area 11 display a black picture.

[0084] In some embodiments, please refer to Figures 2 to 3, the position adjustment module 22 includes a driving unit 221. The driving unit 221 is connected to the display module and / or the image acquisition module 21. The driving unit 221 can be used to control the moving distance of the display module and / or the image acquisition module 21.

[0085] In some embodiments, refer to Figures 2 to 3 , the position adjustment module 22 further includes a displacement detection unit 222.

[0086] The displacement detection unit 222 is used to detect the displacement of the display module and / or the image acquisition module 21. The driving unit 221 is used to control the moving distance of the display module and / or the image acquisition module 21 according to the displacement detected by the displacement detection unit 222. Optionally, the driving unit 221 can be electrically connected to the image acquisition module.

[0087] The driving unit 221 can be used to drive at least one of the display module and the image acquisition module 21 to move, so as to adjust the position of the display module and / or the image acquisition module 21. The displacement detection unit 222 is used to obtain the displacement information of the display module and feedback the displacement information to the driving unit 221 in real time. The cooperation between the driving unit 221 and the displacement detection unit 222 can ensure the accuracy of the displacement of the display module and / or the image acquisition module 21, and realize efficient automatic adjustment. Exemplarily, if the accuracy of controlling the movement of the display module and / or the image acquisition module 21 by using the driving unit 221 alone is at the millimeter level, through the cooperation between the driving unit 221 and the displacement detection unit 222, and the displacement detection unit 222 feeds back the displacement information to the driving unit 221 in real time, the accuracy of the driving unit 221 controlling the movement of the display module and / or the image acquisition module 21 can be improved, for example, it can reach the micron level.

[0088] In some alternative embodiments, the driving unit 221 includes a motor, which has strong actuation characteristics and can achieve fine adjustment of the positions of the display module and / or the image acquisition module 21. Optionally, the driving unit 221 may include a motor driver, etc. Optionally, the driving unit 221 may include a transmission mechanism. The motor may be connected to the display module and / or the image acquisition module 21 through the transmission mechanism. Optionally, the position adjustment module may further include a controller, etc. The controller may be electrically connected to the motor through the motor driver. The controller may be configured to output a control signal to the motor driver according to the displacement of the display module and / or the image acquisition module 21 detected by the displacement detection unit 222, so that the motor driver controls the rotation of the motor, and then drives the display module and / or the image acquisition module 21 to move through the transmission mechanism. The controller may be configured to determine a displacement reference signal according to the image acquired by the image acquisition module 21, and obtain a driving signal through a feedback adjustment algorithm (for example, it may include a proportional-integral adjustment algorithm, etc.) according to the difference between the displacement reference signal and the detected value of the displacement of the display module and / or the image acquisition module 21 detected by the displacement detection unit 222, and output it to the motor driver to control the rotation of the motor, and then control the moving distance of the display module and / or the image acquisition module 21.

[0089] In some alternative embodiments, the displacement detection unit 222 includes a grating scale, which is a measurement feedback device that works based on the optical principle of gratings and can be used for the measurement of linear displacement. At the same time, the grating scale itself has high precision, which can ensure higher moving precision.

[0090] In some embodiments, the transmittance of the first display area 11 is greater than the light transmittance of the second display area 12.

[0091] Both the first display area 11 and the second display area 12 can achieve a display effect. Since the light transmittance of the first display area 11 is greater than the light transmittance of the second display area 12, photosensitive elements such as an in-screen camera can be arranged at the position of the first display area 11 of the display module to realize the corresponding photosensitive function.

[0092] Optionally, the light transmittance of the first display area 11 is greater than or equal to 15%. To ensure that the light transmittance of the first display area 11 is greater than 15%, even greater than 40%, and even has a higher light transmittance, the light transmittance of each functional film layer in the first display area 11 is greater than 80%, and even the light transmittance of at least some functional film layers is greater than 90%.

[0093] In some embodiments, when the image acquisition module 21 and the first display area 11 are in a first preset relative position, the center of the first display area 11 is located at the center of the image captured by the image acquisition module 21, which is equivalent to that the center of the first display area 11 is located at the center of the acquisition area of the image acquisition module 21. The first display area 11 and the image acquisition module 21 may be directly opposite in a direction perpendicular to the display surface of the display module.

[0094] Optionally, the acquisition area of the image acquisition module 21 may be smaller than the size of the first display area 11. When the image acquisition module 21 and the first display area 11 are in a first preset relative position, it is only necessary that the first display area 11 falls within the acquisition area of the image acquisition module 21, and the center of the first display area 11 and the center of the acquisition area of the image acquisition module 21 may or may not coincide.

[0095] Optionally, as Figure 5 shown, the acquisition area of the image acquisition module 21 may be greater than or equal to the size of the first display area 11. When performing parameter debugging on the first display area 11, the center of the first display area 11 is located at the center of the acquisition area 13 of the image acquisition module 21. Compared with the solution where the center of the first display area 11 deviates from the center of the acquisition area 13 of the image acquisition module 21, color deviation can be improved.

[0096] For example, as Figure 5 shown, the first display area 11 is circular, the acquisition area 13 of the image acquisition module 21 is circular, and the first display area 11 and the acquisition area 13 of the image acquisition module 21 are concentric circles. Therefore, the second display area 12 within the acquisition area 13 of the image acquisition module 21 and outside the first display area 11 is an annular shape with the same width, and the light incident amount at each position is the same. As Figure 6 shown, if the center of the first display area 11 deviates from the center of the acquisition area 13 of the image acquisition module 21, the size of the second display area 12 within the acquisition area of the image acquisition module 21 and outside the first display area 11 is uneven, resulting in a deviation in the light incident amount of the second display area entering the acquisition area and causing color deviation.

[0097] As can be seen from the above, when the image acquisition module 21 and the first display area 11 are in a first preset relative position, the image acquisition module 21 can acquire the picture of the first display area 11. Generally, the size of the first display area 11 is smaller than that of the second display area 12. Therefore, in order to further improve the picture accuracy of the first display area 11 acquired by the image acquisition module 21, the embodiment of the present application makes the center of the first display area 11 coincide with the acquisition center of the image acquisition module 21, thereby reducing the risk of the image acquisition module 21 acquiring the picture of the second display area 12 and ensuring the accuracy of the subsequent gamma debugging result of the first display area 11.

[0098] In some embodiments, when the image acquisition module 21 and the second display area 12 are in a second preset relative position, the area of the second display area 12 close to the first display area 11 may be located at the center of the picture acquired by the image acquisition module 21. This is equivalent to the acquisition area of the image acquisition module 21 being located in the second display area 12, and the center of the acquisition area of the image acquisition module 21 being located in the area of the second display area 12 close to the first display area 11. When the image acquisition module 21 and the display module are in the second preset relative position, the image acquisition module 21 and the area of the second display area 12 close to the first display area 11 may be directly opposite in a direction perpendicular to the display surface of the display module.

[0099] Inside the display module, due to the influence of factors such as resistance, the voltage magnitudes at different locations in the second display area 12 are not the same, resulting in slight differences in the display effects of different regions of the second display area 12. In order to improve the display uniformity of the first display area 11 and the second display area 12 and improve the color deviation phenomenon of the first display area 11 and the second display area 12, the embodiments of the present application make the area of the second display area 12 close to the first display area 11 be located at the center of the picture acquired by the image acquisition module 21. Thus, gamma debugging is performed on the second display area 12 through the area of the second display area 12 close to the first display area 11, so that the display effect of the second display area 12 near the first display area 11 is consistent with the display effect of the first display area 11, improving the visual effect for the human eye.

[0100] Please refer to Figure 7 , the embodiments of the present application provide a method for adjusting a display module. The method for adjusting the display module provided by the embodiments of the present application can be implemented based on the display module adjustment device in any of the above embodiments. The display module includes a first display area 11 and a second display area 12, and the adjustment method includes:

[0101] S100: Acquire at least part of the display picture of the display module through an image acquisition module.

[0102] In step S100, the image acquisition module is used to acquire image information within a local area of the display module. Exemplarily, the image acquisition module includes an optical acquisition module.

[0103] S110: When different pictures are displayed in the first display area and the second display area, adjust the position of the display module and / or the image acquisition module according to the image acquired by the image acquisition module, so that the image acquisition module and the display module are in a preset relative position.

[0104] In the embodiments of the present application, through the mutual cooperation between the position adjustment module and the image acquisition module, the precise positioning of the display module and the image acquisition module is ensured. Specifically, if the image information collected by the image acquisition module is different from the image information presented in the first display area of the display module, it indicates that there is a deviation in the relative position between the image acquisition module and the first display area. Then, the position adjustment module adjusts the position of the image acquisition module and / or the display module until the image information collected by the image acquisition module is the same as the image information presented in the first display area. At this time, it indicates that the position of the image acquisition module relative to the first display area is accurate, and the two are in the first preset relative position.

[0105] The adjustment method of the display module provided by the embodiments of the present application can be implemented based on the display module adjustment device in any of the above embodiments. The adjustment method of the display module provided by the embodiments of the present application has the beneficial effects of the above embodiments, which will not be elaborated here.

[0106] It should be noted that the position adjustment module can adjust the relative position between the two by driving the image acquisition module to move, or can also adjust the positional relationship between the two by driving the display module to move.

[0107] In some embodiments, please refer to Figure 8 , the adjustment method further includes:

[0108] S120: When the image acquisition module and the first display area are in the first preset relative position, the parameter debugging module debugs the parameters of the first display area.

[0109] Optionally, when the image acquisition module and the first display area are in the first preset relative position, the parameter debugging module debugs the parameters of the first display area according to the display screen of the first display area collected by the image acquisition module.

[0110] S130: When the image acquisition module and the second display area are in the second preset relative position, the parameter debugging module debugs the parameters of the second display area.

[0111] Optionally, when the image acquisition module and the second display area are in the second preset relative position, the parameter debugging module debugs the parameters of the second display area according to the display screen of the second display area collected by the image acquisition module. The first preset relative position is different from the second preset relative position.

[0112] In steps S120 and S130, in addition to being able to cooperate with the position adjustment module to change the position of the display module and / or the image acquisition module, the image acquisition module can also cooperate with the parameter debugging module to achieve parameter debugging of the display module.

[0113] Optionally, the parameter debugging module includes a gamma debugging module. Optionally, the parameter debugging includes gamma debugging.

[0114] Before the display module leaves the factory, parameter debugging needs to be performed on the first display area and the second display area respectively. For example, it may include gamma debugging. During this process, the image acquisition module is used to acquire the images displayed in the first display area and the second display area respectively to obtain the corresponding image information.

[0115] Specifically, when the image acquisition module is in a first preset relative position with respect to the first display area, the image acquisition module can acquire the image information in the first display area. At this time, the gamma debugging module can cooperate with the image acquisition module to perform gamma debugging on the first display area.

[0116] Similarly, when the image acquisition module is in a second preset relative position with respect to the second display area, the image acquisition module can acquire the image information in the second display area. At this time, the gamma debugging module can cooperate with the image acquisition module to perform gamma debugging on the second display area.

[0117] It should be noted that in the embodiment of the present application, the image acquisition module can be first set to be in the first preset relative position with respect to the first display area, so as to first perform parameter debugging on the first display area. For example, it may include gamma debugging. Then, the position of the display module and / or the image acquisition module is adjusted through the position adjustment module so that the image acquisition module is in the second preset relative position with respect to the second display area. Then, parameter debugging is performed on the second display area. For example, it may include gamma debugging.

[0118] Optionally, the image acquisition module is first set to be in the second preset relative position with respect to the second display area, so as to first perform parameter debugging on the second display area. For example, it may include gamma debugging. Then, when different images are displayed in the first display area and the second display area, according to the images acquired by the image acquisition module, the position of the display module and / or the image acquisition module is adjusted through the position adjustment module so that the image acquisition module is in the first preset relative position with respect to the first display area. Then, parameter debugging is performed on the first display area. For example, it may include gamma debugging.

[0119] In some alternative embodiments, the first display area corresponds to the photosensitive area of the display module, and the second display area corresponds to the normal display area of the display module. The second display area surrounds the outer peripheral side of the first display area. During the parameter debugging (which may include gamma debugging), parameter debugging (which may include gamma debugging) is first performed on the second display area, and then parameter debugging (which may include gamma debugging) is performed on the first display area.

[0120] The transmittance of the first display area is greater than that of the second display area. Therefore, photosensitive device components such as an under-screen camera can be arranged at the position of the first display area of the display module to achieve corresponding photosensitive functions. When displaying a corresponding picture, usually, the second display area will generally become stable faster than the first display area. Therefore, in the embodiments of the present application, the parameters of the second display area are first debugged, which may include, for example, gamma debugging, so as to use this period of time to enable the first display area to display a stable picture, and then the parameters of the first display area are debugged, which may include, for example, gamma debugging, so as to improve the accuracy of parameter debugging (which may include, for example, gamma debugging).

[0121] In some embodiments, when the image acquisition module is at a first preset relative position with respect to the first display area, the gamma debugging module performs gamma debugging on the first display area according to the display picture of the first display area acquired by the image acquisition module.

[0122] In some embodiments, when the image acquisition module is at a second preset relative position with respect to the second display area, the gamma debugging module performs gamma debugging on the second display area according to the display picture of the second display area acquired by the image acquisition module.

[0123] Exemplarily, during the process of performing gamma debugging on the first display area, the image acquisition module continuously acquires and measures the display picture of the first display area to obtain the optical parameters therein. Then, the gamma debugging module can correct the gamma voltage of the first display area as needed until the brightness and gray scale presented by the first display area can conform to the target gamma curve.

[0124] Similarly, during the process of performing gamma debugging on the second display area, the image acquisition module continuously acquires and measures the display picture of the second display area to obtain the optical parameters therein. Then, the gamma debugging module can correct the gamma voltage of the second display area as needed until the brightness and gray scale presented by the second display area can conform to the target gamma curve.

[0125] In some embodiments, the adjustment method further includes: burning the data obtained after the parameter debugging module performs parameter debugging into the display module through a burning module.

[0126] The embodiments of the present application do not limit the order of the above steps and can be set as needed.

[0127] Based on the above embodiments, in some embodiments, please refer to Figure 9 , the adjustment method may include:

[0128] S200: Acquire at least part of the display picture of the display module through an image acquisition module.

[0129] S210: When the image acquisition module and the second display area are in the second preset position, the parameter debugging module performs parameter debugging on the second display area.

[0130] S220: When different images are displayed on the first display area and the second display area, according to the image acquired by the image acquisition module, the position adjustment module adjusts the position of the display module and / or the image acquisition module so that the image acquisition module and the first display area are in the first preset relative position.

[0131] Wherein, the first preset relative position is different from the second preset relative position.

[0132] S230: When the image acquisition module and the first display area are in the first preset relative position, the parameter debugging module performs parameter debugging on the first display area.

[0133] S240: The data obtained after the parameter debugging module performs parameter debugging is burned into the display module by the burning module.

[0134] Optionally, step S240 includes: the gamma data obtained after the gamma debugging module performs gamma debugging is burned into the display module by the burning module. The burning module is used to burn the gamma data corresponding to the first display area and the second display area after debugging into the memory of the display module, so that the display module can respectively obtain the mapping relationship between the target display parameters of the first display area and the second display area and the corresponding data signal parameters, so that the first display area and the second display area can be displayed according to the accurate data signal parameters at different gray levels.

[0135] In some embodiments, step S110 includes:

[0136] When a black screen is displayed on the first display area and the brightness of the display screen of the second display area is greater than the brightness of the black screen, if the brightness of the image acquired by the image acquisition module is less than or equal to the preset brightness value, the position adjustment module stops adjusting the position of the display module and / or the image acquisition module, so that the image acquisition module and the first display area are in the first preset relative position.

[0137] When a black screen is displayed on the first display area and the brightness of the display screen of the second display area is greater than the brightness of the black screen, if the brightness of the image acquired by the image acquisition module is greater than the preset brightness value, the position adjustment module adjusts the position of the display module and / or the image acquisition module.

[0138] A black screen is displayed on the first display area, and a screen with a higher brightness than the black screen is displayed on the second display area. If the brightness corresponding to the image acquired by the image acquisition module is not greater than the preset brightness value, it means that the image acquired by the image acquisition module is all black, then the image acquisition module corresponds to the position of the first display area, and the image acquisition module and the first display area are in the first preset relative position.

[0139] When the brightness corresponding to the picture captured by the image capture module is greater than the preset brightness value, it indicates that the picture captured by the image capture module is not completely black, and at least part of the picture in the second display area is included. At this time, it is necessary to use the position adjustment module to adjust the relative position between the display module and the image capture module. Optionally, the preset brightness value is 0.001 nit.

[0140] In some embodiments, adjusting the position of the display module and / or the image capture module by the position adjustment module includes:

[0141] Detecting the displacement information of the display module and / or the image capture module by the displacement detection unit;

[0142] Controlling the moving distance of the display module and / or the image capture module by the driving unit according to the displacement information of the display module and / or the image capture module detected by the displacement detection unit.

[0143] In some embodiments, the driving unit can determine the moving direction of the display module and / or the image capture module and / or the magnitude of the displacement reference signal according to the change of the difference between the brightness of the image captured by the image capture module and the preset brightness value.
