[0002] In the past two years, the development of the VR (Virtual Reality) industry has led to increasingly higher requirements for the display performance of VR glasses, a core component. High contrast and specific brightness ranges have become important parameters for evaluating the display effect of VR glasses. This necessitates strict control over optical parameters such as brightness during the production of VR displays. Summary of the Invention

[0003] This disclosure provides a parameter adjustment method, apparatus, electronic device, display panel, and storage medium to solve or alleviate one or more technical problems in the prior art.

[0004] As a first aspect of the present disclosure, the present disclosure provides a parameter adjustment method, including:

[0005] The adjustment direction of the brightness control parameters of the display panel is determined based on the brightness of the display panel at the first gray level and the brightness at the second gray level, wherein the first gray level and the second gray level are adjacent.

[0006] Adjust the brightness control parameters of the display panel based on the adjustment direction of the brightness control parameters;

[0007] When the difference between the brightness of the display panel at the first grayscale and the brightness at the second grayscale is reversed, a target parameter value for the brightness control parameter of the display panel is determined based on the current parameter value of the brightness control parameter of the display panel.

[0008] As a second aspect of this disclosure, this disclosure provides a parameter adjustment device, including:

[0009] The adjustment direction determination module is used to determine the adjustment direction of the brightness control parameters of the display panel based on the brightness of the display panel at the first gray level and the brightness at the second gray level, wherein the first gray level and the second gray level are adjacent.

[0010] The parameter adjustment module is used to adjust the brightness control parameters of the display panel based on the adjustment direction of the brightness control parameters;

[0011] The target parameter determination module is used to determine the target parameter value of the brightness control parameter of the display panel based on the current parameter value of the brightness control parameter of the display panel when the difference between the brightness of the display panel in the first gray level and the brightness in the second gray level is reversed.

[0012] As a third aspect of this disclosure, this disclosure provides an electronic device, including:

[0013] At least one processor; and

[0014] A memory communicatively connected to the at least one processor; wherein,

[0015] The memory stores instructions that can be executed by the at least one processor, which, when executed by the at least one processor, enables the at least one processor to perform the parameter adjustment method provided in the embodiments of this disclosure.

[0016] As a fourth aspect of the present disclosure, the present disclosure provides a display panel including the electronic device provided in any embodiment of the present disclosure.

[0017] As a fifth aspect of the present disclosure, the present disclosure provides a non-transitory computer-readable storage medium storing computer instructions for causing a computer to execute the parameter adjustment method provided in the present disclosure.

[0018] As a sixth aspect of the present disclosure, the present disclosure provides a computer program product, including a computer program that, when executed by a processor, implements the parameter adjustment method provided in the present disclosure.

[0019] The technical solution provided in this disclosure determines the adjustment direction of the brightness control parameters of the display panel based on the current brightness of the display panel at the first gray level and the brightness at the second gray level. The brightness control parameters of the display panel are adjusted based on this adjustment direction. When the difference between the brightness of the display panel at the first gray level and the brightness at the second gray level reverses, the target parameter value of the brightness control parameters of the display panel can be accurately determined based on the current parameter value of the brightness control parameters of the display panel. This can avoid the brightness of the display panel from reversing and can also make the brightness of the panel reach the maximum value as much as possible, reducing brightness loss.

[0020] The above overview is for illustrative purposes only and is not intended to be limiting in any way. Further aspects, embodiments, and features of this disclosure will become readily apparent from the accompanying drawings and the following detailed description, in addition to the illustrative aspects, embodiments, and features described above. Attached Figure Description

[0026] Figure 5 This is a structural block diagram of an electronic device according to an embodiment of the present disclosure. Detailed Implementation

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this disclosure. Therefore, the drawings and description are to be considered exemplary in nature and not restrictive.

[0028] During the production, testing, and use of display devices, gamma adjustment is typically performed to ensure that brightness, contrast, and other parameters meet standard requirements. In gamma adjustment schemes, the VOP voltage, which affects the liquid crystal aperture ratio of the display panel, is usually a fixed value provided by the development department after testing. To avoid brightness inversion in the panel, such as the brightness of grayscale L255 being lower than that of grayscale L254 (normally, the brightness of grayscale L255 should be greater than that of grayscale L254), multiple VOP values ​​are set for each batch of panels. The VOP voltage value at 98% of the average brightness is selected as the preferred VOP voltage value for the panel and provided to the factory for mass production. For example, with a product boasting 400 nits brightness, under unchanged backlight conditions, there will be a 2% brightness loss, or 8 nits. When customers have stringent brightness requirements, the factory experiences some yield loss.

[0029] Secondly, due to fluctuations in panel manufacturing processes, the maximum VOP (Volume Point of View) is actually different for each panel. When configuring all panels with a fixed VOP voltage, a mismatch between the maximum VOP value and the panel often occurs, leading to brightness inversion. After adjusting gamma, uneven grayscale transitions appear.

[0030] Therefore, in order to solve the problem of brightness loss and uneven grayscale transition caused by the existing fixed VOP value, this disclosure proposes a scheme for dynamically adjusting the VOP value.

[0031] Figure 1 This is a flowchart of a parameter adjustment method provided in an embodiment of this disclosure. For example... Figure 1 As shown, the parameter adjustment method may include the following steps:

[0032] S110, based on the brightness of the display panel at the first gray level and the brightness at the second gray level, determine the adjustment direction of the brightness control parameters of the display panel, wherein the first gray level and the second gray level are adjacent.

[0033] S120, adjusts the brightness control parameters of the display panel based on the adjustment direction of the brightness control parameters;

[0034] S130: When the difference between the brightness of the display panel in the first grayscale and the brightness in the second grayscale is reversed, the target parameter value of the brightness control parameter of the display panel is determined based on the current parameter value of the brightness control parameter of the display panel.

[0035] In this example, the adjustment direction of the brightness control parameters is determined based on the current brightness of the display panel at the first gray level and the brightness at the second gray level. The brightness control parameters of the display panel are adjusted based on this adjustment direction. When the difference between the brightness of the display panel at the first gray level and the brightness at the second gray level reverses, the target value of the brightness control parameters of the display panel can be accurately determined based on the current value of the brightness control parameters. This can avoid the brightness of the display panel from reversing and can also make the brightness of the panel reach the maximum value as much as possible, reducing brightness loss.

[0036] For example, the first gray level and the second gray level can be selected from 0 to 255 gray levels, where the relationship between the first gray level and the second gray level is simply that they are two adjacent gray levels. For example, the first gray level is 255 and the second gray level is 254. Another example is that the first gray level is 230 and the second gray level is 229. Yet another example is that the first gray level is 254 and the second gray level is 255. The first gray level can be greater than or less than the second gray level.

[0037] For example, generally speaking, the maximum brightness of grayscale 255 is the maximum brightness of the display panel. Therefore, the first grayscale and the second grayscale can be grayscale 255 and grayscale 254, respectively.

[0038] For example, in step S110 above, the initial parameter value of the brightness control parameter of the display panel can be set first, and then the brightness of the display panel in the first grayscale and the brightness in the second grayscale can be obtained to determine the adjustment direction of the brightness control parameter. Alternatively, the initial parameter value can be not set, and the current brightness of the display panel in the first grayscale and the brightness in the second grayscale can be directly obtained to determine the adjustment direction of the brightness control parameter.

[0039] For example, the initial parameter value can be the median, mean, or a value located in the quartile or tertiary of its parameter range. Taking the VOP parameter as an example, it can be the center value of VOP determined based on the VT curve of the panel, and this center value can be used as the initial parameter value.

[0040] For example, the brightness control parameter is a parameter in the display panel used to control the brightness inversion of the display panel, such as the VOP voltage value.

[0041] For example, the adjustment direction of the brightness control parameter can include a direction of increasing or decreasing the parameter value. The increasing direction can include an incremental direction, a random increasing direction, or an increasing direction following a set straight line or curve. The decreasing direction can include a decreasing direction, a random decreasing direction, or a decreasing direction following a set straight line or curve.

[0042] For example, in steps S120 to S130 above, when adjusting the brightness control parameters of the display panel, each time the brightness control parameters of the display panel are set, the brightness of the display panel at the first gray level and the brightness at the second gray level are obtained, and it is determined whether the difference between the brightness at the first gray level and the brightness at the second gray level has reversed. For example, during the adjustment process, the brightness at gray level 255 is always higher than the brightness at gray level 254. As the parameter value continues to increase, the brightness at gray level 255 becomes less than the brightness at gray level 254, and the difference between the two reverses. At this time, it can be considered that a brightness reversal has occurred. As another example, during the parameter adjustment process, the brightness at gray level 255 is always less than the brightness at gray level 254. As the parameter value continues to decrease, the brightness at gray level 255 becomes greater than the brightness at gray level 254, and the difference between the two reverses. At this time, it can be considered that the brightness reversal state has changed to a normal state.

[0043] For example, if the first gray level is higher than the second gray level, step S110 above, based on the brightness of the display panel at the first gray level and the brightness at the second gray level, determines the adjustment direction of the brightness control parameters of the display panel, including:

[0044] If the brightness of the display panel at the first gray level is greater than the brightness at the second gray level, the adjustment direction of the brightness control parameter of the display panel is determined to be the increasing direction.

[0045] For example, if the brightness at grayscale 255 is greater than the brightness at grayscale 254, then the adjustment direction of the brightness control parameter of the display panel is determined to be increasing, that is, the parameter value of the brightness control parameter of the display panel is adjusted by increasing.

[0046] For example, step S120 above, adjusting the brightness control parameters of the display panel based on the brightness control parameter adjustment direction, includes:

[0047] Given that the adjustment direction of the brightness control parameter value is determined to be increasing, the parameter value of the brightness control parameter of the display panel is increased incrementally based on the parameter step value of the brightness control parameter of the display panel.

[0048] For example, when determining that the adjustment direction of the VOP value is incremental, the parameter step value Vt of the VOP value is determined. Using the current VOP value as the initial value Vo, the VOP value can be sequentially increased as V = Vo + n * Vt, where n is the number of increments. The first VOP value is set to V = Vo + Vt, the next value is set to V = Vo + 2 * Vt, and the value after that is V = Vo + 3 * Vt. The interval between two adjacent times can be the same or different, as long as they are set sequentially.

[0049] In some embodiments, if the brightness does not change much after setting the parameter values ​​of the brightness control parameters in sequence, the parameter step value can be adjusted, for example, by increasing the parameter step value.

[0050] For example, step S130 above, which determines the target parameter value of the brightness control parameter of the display panel based on the current parameter value of the brightness control parameter of the display panel, includes:

[0051] The difference between the current parameter value and the parameter step value of the display panel's brightness control parameter is determined as the target parameter value of the display panel's brightness control parameter.

[0052] For example, when the brightness at grayscale 255 is greater than that at grayscale 254, the VOP value is increased incrementally until the brightness at grayscale 255 is less than that at grayscale 254. At this point, the VOP value is stopped. Since the current VOP value has already caused the brightness to reverse, the previous value will not cause the brightness to reverse. Therefore, the previous VOP value is the maximum VOP value that the panel VOP can be set to, which allows the panel to reach maximum brightness at grayscale 255 without causing the brightness to reverse.

[0053] For example, if the first gray level is higher than the second gray level, step S110 above, based on the brightness of the display panel at the first gray level and the brightness at the second gray level, determines the adjustment direction of the brightness control parameters of the display panel, including:

[0054] If the brightness of the display panel at the first gray level is less than the brightness at the second gray level, the adjustment direction of the brightness control parameter of the display panel is determined to be decreasing.

[0055] For example, if the brightness at grayscale 255 is less than the brightness at grayscale 254, it indicates that the panel is currently in a brightness inversion state. The normal brightness state should be that the brightness at grayscale 255 is greater than the brightness at grayscale 254. That is, the brightness order of two adjacent grayscale levels should be the same as their grayscale order. If the two orders are reversed, the brightness is inverted. In this case, the VOP value needs to be decreased, and the brightness control parameter should be adjusted in a decreasing direction.

[0056] For example, step S120 above, adjusting the brightness control parameters of the display panel based on the brightness control parameter adjustment direction, includes:

[0057] When the adjustment direction of the brightness control parameter value is determined to be a decreasing parameter value, the parameter value of the brightness control parameter of the display panel is decreased based on the parameter step value of the brightness control parameter of the display panel.

[0058] For example, if the brightness at grayscale 255 is less than the brightness at grayscale 254, then the adjustment direction of the brightness control parameter of the display panel is determined to be decreasing, that is, the parameter value of the brightness control parameter of the display panel is adjusted to decrease.

[0059] For example, when determining that the adjustment direction of the VOP value is decreasing, the parameter step value Vt of the VOP value is determined. Using the current VOP value as the initial value Vo, the VOP value can be sequentially increased and decreased as follows: V = Vo - n * Vt. Here, n is the number of decreases. The first VOP value is set to V = Vo - Vt, the next value is set to V = Vo - 2 * Vt, and the next value is set to V = Vo - 3 * Vt. The interval between two adjacent times can be the same or different, as long as they are set sequentially.

[0060] For example, step S130 above, which determines the target parameter value of the brightness control parameter of the display panel based on the current parameter value of the brightness control parameter of the display panel, includes:

[0061] The current value of the display panel's brightness control parameters will be used as the target value for the display panel's brightness control parameters.

[0062] For example, when the brightness at grayscale 255 is less than that at grayscale 254, the VOP value is decreased until the brightness at grayscale 255 is greater than that at grayscale 254. At this point, the VOP value is stopped. The current VOP value causes the panel to switch from a brightness reversal state to a normal brightness state. Therefore, the current VOP value is the maximum VOP value that can be set for the panel. It can make the panel reach the maximum brightness at grayscale 255 without brightness reversal.

[0063] In some embodiments, the display panel has a maximum brightness setting. If the current target parameter value causes the panel brightness to exceed the set threshold, the VOP value needs to be reduced.

[0064] Taking a direct-lit backlight panel as an example, after determining the target VOP value, if the brightness exceeds the standard, the brightness can be reduced by lowering the MLED backlight.

[0065] Taking a side-lit backlight panel as an example, if the brightness is too bright under a fixed current, exceeding the maximum brightness, the VOP needs to be adjusted to make its brightness meet the requirements, such as 80nit to 110nit.

[0066] For example, the above method may further include:

[0067] Configure the brightness control parameters of the display panel to the target parameter value;

[0068] If the brightness of the display panel in the first grayscale is greater than the set brightness threshold, the brightness control parameter of the display panel is decreased from the target parameter value based on the parameter step value of the brightness control parameter of the display panel until the brightness of the display panel in the first grayscale is less than the brightness threshold. The current parameter value of the brightness control parameter of the display panel is then determined as the target parameter value of the brightness control parameter of the display panel.

[0069] For example, when the VOP value of the display panel is set to the maximum VOP value determined above, the brightness of grayscale L255 is greater than 110 nits. Then, the VOP value of the display panel is reduced sequentially until the brightness of the panel in grayscale L255 reaches the target range. Then, the current VOP value of the panel is taken as the maximum VOP value.

[0070] like Figure 2 As shown, the following will describe an application example of adjusting the VOP value of the panel according to this disclosure.

[0071] When setting the VOP value of the panel, first set an initial VOP value and collect the brightness at L255 and L254 gray levels; if the brightness of L255 is greater than the brightness of L254, increase the VOP value in a set step until the brightness of L255 is less than the brightness of L254, then use the previous VOP value as the target VOP value of the panel; if the brightness of L255 is less than the brightness of L254, decrease the VOP value in a set step until the brightness of L255 is greater than the brightness of L254, then use the current VOP value as the target VOP value of the panel.

[0072] Therefore, if each panel uses this scheme to determine its VOP value, the VOP value set for each panel will be optimal for that panel, reducing brightness loss and grayscale unevenness.

[0073] like Figure 3 As shown, another application example of adjusting the VOP value of the panel will be described below.

[0074] When determining the target VOP value, if the L255 brightness is >110 nits, the VOP value is decreased in fixed steps until the L255 brightness reaches the target range.
