[0002] The human eye's perception of brightness is nonlinear, that is, for small changes in brightness, the human eye is relatively sensitive in dark areas, but relatively insensitive in bright areas. In order to compensate for this nonlinear perception, the display device simulates the perception characteristics of the human eye through gamma debugging and stores the corresponding gamma curve. When displaying, the display device drives the display panel to display the image by calling the pre-stored gamma curve, so that the color and brightness of the image are more in line with the natural perception of the human eye, and it can also optimize the image's contrast, shadow details and color reproduction.
[0003] When the display panel is gamma-adjusting, it is necessary to continuously obtain the current brightness of the display panel and make the brightness reach the expected value by changing the grayscale signal provided to the display panel. However, as the brightness requirements of the display panel gradually increase, the range of the existing optical probe may not cover the required brightness range, resulting in the inability to accurately complete the gamma adjustment under high brightness, and thus the inability to obtain an accurate gamma curve.

[0020] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present disclosure, the scheme of the embodiments of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other without conflict.
[0021] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the present disclosure, but the embodiments of the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.
[0022] The gamma curve is a nonlinear relationship curve that describes the output brightness of the display panel and the input grayscale signal during the gamma adjustment process. The goal of gamma debugging is to make the relationship between the grayscale input and the output brightness of the display panel conform to the expected gamma curve. Therefore, when the display panel is performing gamma debugging, it is necessary to continuously obtain the current brightness of the display panel.
[0023] In related technologies, the maximum brightness that display panels can achieve has gradually increased, evolving toward 8000 nit and 10000 nit. However, the range of optical probes used for gamma debugging is usually below 5000 nit. Optical probes with a large range are expensive, and replacing probes will undoubtedly increase the cost of gamma debugging.
[0024] In view of this, an embodiment of the present disclosure provides a display panel gamma debugging method. Specifically, the display panel can be an OLED (Organic Light-Emitting Diode) display panel, or it can be a Micro LED (micro light-emitting diode) display panel, LCD (Liquid Crystal Display) display panel, and other types of display panels, which are not limited here.
[0025] like Figure 1 As shown, the above method includes:
[0026] S1. Detect the current brightness of the display panel 10 using the brightness detection device 20, and perform gamma adjustment on the display panel 10 based on the current brightness.
[0027] In a specific implementation, the brightness detection device 20 may be an optical sensor (such as a color analyzer, etc.). Figure 2 As shown, during the execution of S1 , the brightness detection device 20 is disposed on the light-emitting side of the display panel 10 and receives the emitted light L of the display panel 10 , thereby acquiring the above-mentioned current brightness.
[0028] In response to the current brightness detected by the brightness detection device 20 being greater than or equal to the first threshold, S2 is executed to enable the brightness detection device 20 to detect the current brightness of the display panel 10 through the filter module 30 with a transmittance of the first transmittance, and gamma adjustment is performed on the display panel 10 based on the current brightness. The first transmittance is less than 100%. In specific implementation, the first transmittance can be selected as an appropriate value according to the range of the brightness detection device 20 actually used and the maximum brightness of the display panel 10, which is not limited here.
[0029] like Figure 3 As shown, during the execution of S2, the filter module 30 is located between the light-emitting side of the display panel 10 and the brightness detection device 20. It can be understood that Figure 3 It is only used to illustrate the approximate positional relationship between the display panel 10, the brightness detection device 20 and the filter module 30, and does not limit the distance ratio between the display panel 10, the brightness detection device 20 and the filter module 30. In a specific implementation, the position of the filter module 30 needs to make all the output light L of the display panel 10 pass through the filter module 30 before reaching the brightness detection device 20. Based on this, the filter module 30 can directly cover the side of the brightness detection device 20 that receives the light signal; in another embodiment, the filter module 30 can also be as Figure 3 As shown, there is a certain distance from the brightness detection device 20 , provided that the distance satisfies the condition that all the outgoing light L of the display panel 10 first passes through the light filtering module 30 and then reaches the brightness detection device 20 .
[0030] The brightness of the output light of the display panel 10 will decay after passing through the filter module 30. For example, the actual brightness of the output light of the display panel 10 is 5000nit. After passing through the filter module 30 with a transmittance of 50%, the brightness decays to 2500nit. At this time, the brightness detection device 20 with a range less than 5000nit can still be used for gamma adjustment of the display panel 10. The method provided in the embodiment of the present disclosure can complete the gamma adjustment of the high-brightness display panel by adding a low-cost filter module without replacing the expensive large-range brightness detection device, thereby accurately completing the gamma adjustment under high brightness and saving the cost of the gamma adjustment link.
[0031] Specifically, the first threshold is less than or equal to the range of the brightness detection device 20 .
[0032] For example, when the measuring range of the brightness detection device 20 is 5000nit, the first threshold value can be set to 5000nit, that is, when the brightness of the display panel 10 reaches the limit that the brightness detection device 20 can measure, the filter module 30 is added; when the measuring range of the brightness detection device 20 is 5000nit, the first threshold value can also be set to 4950nit, and the first threshold value is slightly smaller than the measuring range, that is, the filter module 30 is added in advance to avoid the execution process of adding the filter module 30 affecting the detection of the brightness value before and after the measuring range.
[0033] In specific implementation, the gamma adjustment of the display panel 10 based on the current brightness in the above S1 and S2 may include:
[0034] S01, set the target grayscale. The target grayscale can be selected from 0 to 255. The complete gamma adjustment process requires that each grayscale from 0 to 255 be used as the target grayscale for gamma adjustment.
[0035] S02. Continuously adjust the data signal provided to the light-emitting element in the display panel 10 so that the current brightness of the display panel 10 reaches the expected brightness. The expected brightness is the brightness value corresponding to the above-mentioned target grayscale in the target gamma curve. According to different display requirements and display panel 10 models, there are multiple commonly used gamma curves in the industry, and the gamma 2.2 curve is one of them. In the gamma 2.2 curve, every time the input signal (grayscale value or voltage value) doubles, the output brightness will increase exponentially, that is, increase to the 2.2th power of the original brightness. The above-mentioned target gamma curve can be a gamma 2.2 curve, or it can be other commonly used gamma curves.
[0036] S03, storing the correspondence between the target grayscale and the data signal finally provided to the light-emitting element in the display panel 10. When the display panel 10 is used to display a picture, the external device provides the display panel 10 with the grayscale corresponding to each light-emitting element in the next frame of the picture, and the display panel 10 provides the corresponding data signal to each light-emitting element based on the correspondence between the grayscale and the data signal obtained in S01 to S03.
[0037] The above S01 to S03 are only exemplary. In specific implementations, those skilled in the art may perform the above steps of gamma debugging the display panel 10 based on the current brightness in different ways based on the method provided in the embodiment of the present disclosure, which are all within the protection scope of the present disclosure.
[0038] In some embodiments, Figure 4 As shown, in the above S1, the step of using the brightness detection device 20 to detect the current brightness of the display panel 10 includes:
[0039] When the current brightness detected by the brightness detection device 20 is less than the first threshold value, execute S11, so that the brightness detection device 20 detects the current brightness of the display panel 10 through the filter module 30 with a transmittance of the second transmittance, wherein the second transmittance is greater than the first transmittance; or, the brightness detection device 20 detects the current brightness of the display panel 10 without passing through the filter module 30.
[0040] In a specific implementation, the filter module 30 may be a device with non-adjustable transmittance, such as a filter unit. In this embodiment, the above S2 and S11 need to be implemented by moving the position of the filter module 30. For example, when S11 is executed, the brightness detection device 20 directly detects the current brightness of the display panel 10 without using the filter module 30. When S2 is executed, the filter module 30 with the first transmittance is moved to between the light exit side of the display panel 10 and the brightness detection device 20 (such as Figure 3 As shown), the brightness detection device 20 detects the current brightness of the display panel 10 through the filter module 30 with a first transmittance; in other embodiments, the filter module 30 may also be a device with adjustable transmittance, such as a liquid crystal unit. In this embodiment, the above S2 and S11 may not be implemented by moving the position of the filter module 30. For example, when executing S2 and S11, the filter module 30 is always located between the light emitting side of the display panel 10 and the brightness detection device 20. The difference is that the transmittance of the filter module 30 when executing S11 is higher (i.e., the second transmittance mentioned above), and the transmittance of the filter module 30 when executing S2 is lower (i.e., the first transmittance mentioned above), thereby attenuating the brightness of the display panel 10.
[0041] The basic working mechanism of the brightness detection device 20 includes the generation of photogenerated carriers under illumination, the diffusion or drift of carriers to form current, and the amplification of photocurrent in the amplifier circuit and conversion into a voltage signal. Under low brightness conditions, the number of photogenerated carriers decreases, resulting in a weaker current, which affects the measurement accuracy of the brightness detection device 20. At the same time, external interference will also affect the measurement accuracy of the brightness detection device 20 under low brightness. Therefore, the brightness detection device 20 usually has an accuracy threshold, that is, only the brightness above this threshold can be accurately detected. In some embodiments, the accuracy threshold is 1% to 3% of the range of the brightness detection device 20.
[0042] In summary, if the brightness detection device 20 detects the current brightness of the display panel 10 through the filter module 30 with low transmittance when the brightness of the display panel 10 is low, the low brightness will be further attenuated, causing it to be lower than the accuracy threshold of the brightness detection device 20, affecting the detection accuracy of the brightness detection device 20. In the above embodiment of the present disclosure, the brightness of the display panel 10 is attenuated through the filter module 30 only when the brightness is higher than a certain threshold, thereby ensuring the detection accuracy of the brightness detection device 20 at full brightness, and then accurately completing the gamma adjustment of the display panel 10 at full brightness.
[0043] In some embodiments, Figure 5 As shown, the method provided by the embodiment of the present disclosure also includes:
[0044] In response to the current brightness detected by the brightness detection device 20 through the filter module 30 being less than or equal to the second threshold, S3 is executed to increase the transmittance of the filter module 30; or, the brightness detection device 20 does not detect the current brightness of the display panel 10 through the filter module 30. Specifically, the second threshold, i.e., the above-mentioned accuracy threshold, can be 1% to 3% of the range of the brightness detection device 20.
[0045] The above-mentioned embodiment of the present disclosure improves the brightness of the display panel 10 reaching the brightness detection device 20 when the brightness is less than or equal to the second threshold, thereby avoiding excessive attenuation of the brightness of the filter module 30 with low transmittance at low brightness, thereby ensuring the detection accuracy of the brightness detection device 20.
[0046] In a specific implementation, the filter module 30 may be a device with non-adjustable transmittance, such as a filter unit. In this embodiment, the above S3 may be achieved by moving the position of the filter module 30, for example, moving the filter module 30 with a first transmittance from a position between the light emitting side of the display panel 10 and the brightness detection device 20, so that the brightness detection device 20 directly detects the current brightness of the display panel 10 without passing through the filter module 30; in other embodiments, the filter module 30 may also be a device with adjustable transmittance, such as a liquid crystal unit. In this embodiment, the above S3 may improve the transmittance of the filter module 30 by changing the deflection angle of the liquid crystal molecules.
[0047] In some embodiments, Figure 6 As shown, the method provided by the embodiment of the present disclosure also includes:
[0048] In response to the current brightness detected by the brightness detection device 20 through the filter module 30 being greater than or equal to the first threshold, S4 is executed to reduce the transmittance of the filter module 30 .
[0049] When the brightness detection device 20 detects the current brightness of the display panel 10 through the filter module 30, it means that the actual brightness of the display panel 10 at this time has exceeded the first threshold value. If the current brightness detected by the brightness detection device 20 through the filter module 30 is greater than or equal to the first threshold value, it means that the actual brightness of the display panel 10 at this time far exceeds the range of the brightness detection device 20, and it is necessary to reduce the transmittance of the filter module 30, thereby ensuring that the brightness detection device 20 with a small range completes the gamma adjustment of the high-brightness display panel 10. At the same time, considering the problem of the accuracy threshold of the above-mentioned brightness detection device 20, the above-mentioned embodiment of the present disclosure uses distributed filtering instead of directly using the filter module 30 with lower transmittance, so as to avoid the filter module 30 with lower transmittance from excessively attenuating the brightness at low brightness, thereby ensuring the detection accuracy of the brightness detection device 20.
[0050] In a specific implementation, the filter module 30 may be a device with non-adjustable transmittance, such as a filter unit. In this embodiment, the above S4 may be executed by increasing the number of filters. In other embodiments, the filter module 30 may also be a device with adjustable transmittance, such as a liquid crystal unit. In this embodiment, the above S4 may be executed by changing the deflection angle of the liquid crystal molecules.
[0051] In some embodiments, the filter module 30 in the above embodiments includes at least one filter.
[0052] In the above S2, the step of enabling the brightness detection device 20 to detect the current brightness of the display panel 10 through the filter module 30 with a first transmittance includes:
[0053] Move at least one filter with a total light transmittance of the first light transmittance to between the brightness detection device 20 and the light emitting side of the display panel 10 (such as Figure 3 As shown), the brightness detection device 20 detects the current brightness of the display panel 10 through at least one filter.
[0054] In specific implementation, the brightness detection device 20 can detect the current brightness of the display panel 10 without passing through the filter module 30 by moving at least one filter out from the position between the light emitting side of the display panel 10 and the brightness detection device 20; improving the transmittance of the filter module 30 can be achieved by reducing the filters, and reducing the transmittance of the filter module 30 can be achieved by adding filters.
[0055] In a specific implementation, the first light transmittance and the second light transmittance can be achieved by superposition of one filter or multiple filters, and the number of filters is not limited.
[0056] In some embodiments, the filter module 30 in the above embodiment includes liquid crystal molecules. Specifically, the filter module 30 is an electrically controlled liquid crystal glass, including two layers of glass plates and two layers of transparent electrodes, the liquid crystal molecules are sandwiched between the glass plates and the transparent electrodes, and the deflection direction of the liquid crystal molecules can be changed by applying a voltage to the transparent electrodes, thereby changing the light transmittance of the filter module 30.
[0057] In the above S2, the step of enabling the brightness detection device 20 to detect the current brightness of the display panel 10 through the filter module 30 with a first transmittance includes:
[0058] The deflection direction of the liquid crystal molecules in the filter module 30 is changed to make the transmittance of the filter module 30 the first transmittance, so that the brightness detection device 20 detects the current brightness of the display panel 10 through the filter module 30 .
[0059] In specific implementation, increasing or decreasing the light transmittance of the filter module 30 can be achieved by changing the deflection direction of the liquid crystal molecules.
[0060] In some embodiments, Figure 7 As shown, the above S2 includes:
[0061] S21 , enabling the brightness detection device 20 to detect the current brightness of the display panel 10 through the filter module 30 with a first transmittance.
[0062] S22. Divide the current brightness by the first light transmittance to obtain actual brightness.
[0063] S23 , performing gamma adjustment on the display panel 10 based on the actual brightness.
[0064] For example, when the first transmittance is 50% and the current actual brightness of the display panel 10 is 5000 nit, the current brightness detected by the brightness detection device 20 after the filtering module 30 is 5000 nit×50%=2500 nit, but at this time the grayscale corresponding to the brightness of 5000 nit should be gamma adjusted, so the current brightness of 2500 nit needs to be divided by the first transmittance of 50% to obtain the actual brightness of 5000 nit.
[0065] Based on the above embodiment, the above S02 may include:
[0066] The data signal provided to the light-emitting element in the display panel 10 is continuously adjusted, and the current brightness is divided by the first transmittance to obtain the actual brightness, so that the actual brightness of the display panel 10 reaches the desired brightness.
[0067] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the above method.
[0068] It should be noted that the above describes some embodiments of the present application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the above embodiments and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or continuous order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
[0069] Based on the same inventive concept, corresponding to any of the above-mentioned embodiments and methods, the present application also provides a display panel gamma adjustment device, including a brightness detection device 20, a filter module 30, a control module 40 and a gamma adjustment module 50, such as Figure 3 and Figure 8 As shown (specifically, Figure 3 The positional relationship among the display panel 10, the brightness detection device 20 and the filter module 30 is shown. Figure 8 The figure shows the communication connection relationship among the display panel 10, the brightness detection device 20, the filter module 30, the control module 40 and the gamma adjustment module 50).
[0070] Specifically, the brightness detection device 20 is used to detect the current brightness of the display panel 10. The control module 40 is used to make the brightness detection device 20 detect the current brightness of the display panel 10 through the filter module 30 with a transmittance of the first transmittance in response to the current brightness detected by the brightness detection device 20 being greater than or equal to the first threshold, wherein the first transmittance is less than 100%. The gamma debugging module 50 is used to perform gamma debugging on the display panel 10 based on the current brightness.
[0071] The device provided by the embodiment of the present disclosure can complete the gamma debugging of the high-brightness display panel by adding a low-cost filter module, without replacing the expensive large-range brightness detection device, thereby accurately completing the gamma debugging under high brightness while saving the cost of the gamma debugging link.
[0072] Specifically, the control module 40 and the gamma debugging module 50 may be located in the same electronic device and perform different functions accordingly. In other embodiments, the control module 40 and the gamma debugging module 50 may also be different electronic devices. For example, the control module 40 may be a machine for controlling the filter module 30; the gamma debugging module 50 is a device used in gamma debugging in the related art.
[0073] In one embodiment, if Figure 8 As shown, the gamma debugging module 50 is connected to the brightness detection device 20 and the control module 40 in communication (the gamma debugging module 50 can be directly connected to the control module 40 in communication, or can be connected to the control module 40 in communication through other master control modules), and the gamma debugging module 50 receives the current brightness fed back by the brightness detection device 20. In response to the current brightness detected by the brightness detection device 20 being greater than or equal to the first threshold, the gamma debugging module 50 sends an enable signal to the control module 40, and the control module 40 responds to the enable signal to enable the brightness detection device 20 to detect the current brightness of the display panel 10 through the filter module 30 with a transmittance of the first transmittance, and sends a feedback signal to the gamma debugging module 50 at the same time, and the gamma debugging module 50 responds to the feedback signal to perform gamma debugging on the display panel 10 based on the current brightness. The process of controlling other states of the filter module 30 is the same as the above process, and will not be repeated.
[0074] In some embodiments, the filter module 30 in the above embodiments includes at least one filter.
[0075] The control module 40 is specifically used for:
[0076] Move at least one filter with a total light transmittance of the first light transmittance to between the brightness detection device 20 and the light emitting side of the display panel 10 (such as Figure 3 As shown), the brightness detection device 20 detects the current brightness of the display panel 10 through at least one filter.
[0077] In a specific implementation, the control module 40 may also be used to move at least one filter out from a position between the light emitting side of the display panel 10 and the brightness detection device 20 , and to reduce or increase the number of filters.
[0078] In some embodiments, the filter module 30 in the above embodiment includes liquid crystal molecules. Specifically, the filter module 30 is an electrically controlled liquid crystal glass, including two layers of glass plates and two layers of transparent electrodes, the liquid crystal molecules are sandwiched between the glass plates and the transparent electrodes, and the deflection direction of the liquid crystal molecules can be changed by applying a voltage to the transparent electrodes, thereby changing the light transmittance of the filter module 30.
[0079] The control module 40 is specifically used for:
[0080] The deflection direction of the liquid crystal molecules in the filter module 30 is changed to make the transmittance of the filter module 30 the first transmittance, so that the brightness detection device 20 detects the current brightness of the display panel 10 through the filter module 30 .
[0081] For the convenience of description, the above device is described in terms of functions divided into various modules. Of course, when implementing the present application, the functions of each module can be implemented in the same or multiple software and / or hardware.
[0082] The device of the above embodiment is used to implement the corresponding display panel gamma adjustment method in any of the above embodiments, and has the beneficial effects of the corresponding method embodiment, which will not be described in detail here.

[0084] like Fig. 9 As shown, the electronic device may include a processor 1101 and a memory 1102 storing computer program instructions.
[0085] Specifically, the processor 1101 may include a central processing unit (CPU), or an application specific integrated circuit (ASIC), or may be configured to implement one or more integrated circuits of the embodiments of the present application.

By way of example and not limitation, the memory 1102 may include a hard disk drive (HDD), a floppy disk drive, a flash memory, an optical disk, a magneto-optical disk, a tape, or a universal serial bus (USB) drive or a combination of two or more of these. Where appropriate, the memory 1102 may include a removable or non-removable (or fixed) medium. Where appropriate, the memory 1102 may be inside or outside the integrated gateway device.
