Description

一种亮度补偿方法、可折叠显示装置及存储介质Brightness compensation method, foldable display device and storage medium 技术领域Technical field
本发明涉及显示领域，尤其涉及一种亮度补偿方法、可折叠显示装置及存储介质。The present invention relates to the field of display, and in particular to a brightness compensation method, a foldable display device, and a storage medium.
背景技术Background technique
随着人们对移动终端显示区域的需求越来越大，移动终端的尺寸正在朝着越来越大的趋势发展。然而，随着尺寸的增大，移动终端的便携性成为亟待解决的问题。可折叠显示装置的出现解决了这一问题。可折叠显示装置具有完全展开状态，即所有的子屏幕完全展开形成一个共同显示的屏幕，满足了用户对尺寸的需求；完全折叠状态，即所有的子屏幕通过卷绕、折叠等方式使该移动终端的尺寸达到最小化，满足了人们对便携性的需求；以及中间状态，即子屏幕之间未完全展开，但移动终端亦未达到尺寸最小化的状态。尤其在中间状态下，移动终端中只有一部分子屏幕处于被使用状态，或者各个子屏幕在共同使用，但由于被分别设置成了不同的显示模式，随着使用时间的累积，各个子屏幕的亮度衰减程度亦不同。如此，在完全展开状态下，或者若干连续子屏幕形成共屏共同显示一显示界面的情况下，由于各个子屏幕亮度衰减程度不一致，会导致各个分屏的亮度不致，即，同一显示画面出现不同的亮度值，这会严重影响用户体验。With the increasing demand for the display area of mobile terminals, the size of mobile terminals is developing towards an increasing trend. However, as the size increases, the portability of mobile terminals becomes an urgent problem to be solved. The advent of foldable display devices has solved this problem. The foldable display device has a fully expanded state, that is, all the sub-screens are fully expanded to form a common display screen, which meets the user's size requirements; a fully folded state, that is, all the sub-screens are moved by winding, folding, etc. The size of the terminal is minimized to meet people's needs for portability; and the intermediate state, that is, the sub-screens are not fully expanded, but the mobile terminal has not reached the state of minimum size. Especially in the intermediate state, only a part of the sub-screens in the mobile terminal are in use, or the sub-screens are used together, but because they are set to different display modes, the brightness of each sub-screen is accumulated with the use time The degree of attenuation is also different. In this way, in the fully expanded state, or in the case where several consecutive sub-screens form a common screen and display a display interface together, due to the inconsistent brightness attenuation of each sub-screen, the brightness of each split screen will be inconsistent, that is, the same display screen will appear different The brightness value, which will seriously affect the user experience.

具体实施方式detailed description
下面，结合附图以及具体实施方式，对本发明做进一步描述，需要说明的是，在不相冲突的前提下，以下描述的各实施例之间或各技术特征之间可以任意组合形成新的实施例。In the following, the present invention will be further described in conjunction with the drawings and specific implementations. It should be noted that, without conflict, the various embodiments described below or the technical features can be arbitrarily combined to form new embodiments. .
图1为本发明一实施例提供的亮度补偿方法的应用场景图，该亮度补偿方法应用于可折叠显示装置。可折叠显示装置包括可绕转轴相对转运的多个子屏幕，或者整体可任意弯曲或卷绕的柔性屏，或者两者的结合，以及其他具有实现共同显示的展开状态和关闭显示功能或分别显示的折叠状态的显示装置。在一非限制性实施例中，可折叠显示装置的多个子屏幕(包括两个及两个以上)包括多个间隔设置的折弯部11和非折弯部12。上下文所指的“共显状态”表示该可折叠显示装置的至少两个子屏幕共同构成同一个显示界面。具体地，该至少两个子屏幕为连续的，即中间未间隔有除该至少两个子屏幕之外的其他子屏幕。而该共同构成同一显示界面的子屏幕即为上下文所指的“共显子屏幕”。需要特别指出的是，这里的“共显子屏幕”并非一个静态的概念，即在不同的显示状态下，该“共显子屏幕”所指代的子屏幕是不同的。例如，可折叠显示装置1包括依次可转动连接的子屏幕A，B，C(图中未示出)，当可折叠显示装置完全展开时，共显子屏幕表示包括子屏幕A，B，C；当可折叠显示装置1完全折叠时，则此时该可折叠显示装置1处于非共显状态下，因此不存在共显子屏幕。当A，B共同构成同一显示界面，而C单独显示或者不显示时，A，B即为该共显子屏幕；而当B，C共同构成同一显示界面，而A单独显示或者不显示时，B，C即为该共显子屏幕。FIG. 1 is an application scene diagram of a brightness compensation method according to an embodiment of the present invention. The brightness compensation method is applied to a foldable display device. The foldable display device includes a plurality of sub-screens that can be relatively transported around a rotation axis, or a flexible screen that can be bent or wound arbitrarily as a whole, or a combination of the two, and other functions that have a common display expansion state and a closed display function or are displayed separately Display device in folded state. In a non-limiting embodiment, the plurality of sub-screens (including two or more) of the foldable display device includes a plurality of bending portions 11 and non-bending portions 12 which are arranged at intervals. The "co-display state" referred to in the context means that at least two sub-screens of the foldable display device together constitute the same display interface. Specifically, the at least two sub-screens are continuous, that is, there are no sub-screens other than the at least two sub-screens in between. The sub-screens that together constitute the same display interface are referred to as "co-display sub-screens" in context. It should be particularly pointed out that the "co-display sub-screen" here is not a static concept, that is, the sub-screens referred to by the "co-display sub-screen" are different in different display states. For example, the foldable display device 1 includes sub-screens A, B, and C (not shown in the figure) that are connected in turn, and when the foldable display device is fully expanded, the co-display sub-screen indicates that the sub-screens A, B, and C are included. When the foldable display device 1 is completely folded, then the foldable display device 1 is in a non-co-display state, so there is no co-display sub-screen. When A and B together form the same display interface, and C displays or does not display separately, A and B are the co-display sub-screens; and when B and C together form the same display interface, and A displays or does not display separately, B and C are the co-display screens.
如图2所示，本发明一实施例提供的亮度补偿方法，包括：As shown in FIG. 2, the brightness compensation method provided by an embodiment of the present invention includes:
步骤S101：检测处于该共显状态下的至少两个共显子屏幕所对应的至少两个亮度衰减值，该至少两个共显子屏幕共同构成同一显示界面。Step S101: Detect at least two brightness attenuation values corresponding to at least two co-display sub-screens in the co-display state, and the at least two co-display sub-screens together constitute the same display interface.
其中，多个子屏幕分别具有初始使用时的初始亮度值，存储器中存储有子屏幕的累计使用时长与亮度衰减值的映射关系。具体地，该可折叠显示装置还包括用于分别统计每个子屏幕的累计使用时长的计时器，该计时器可以由软件 实现，也可以为具体的硬件装置。在另一应用实例中，该累计使用时长为理论使用时长，该理论使用时长例如可以为该子屏幕在第一驱动电流或电压驱动下的亮度下的实际使用时长；当该子屏幕的显示状态为对比度较高或者亮度需求比较高的内容时，其理论使用时长要大于该实际使用的时长；反之，则小于该实际使用的时长。具体折算方式例如可以通过其所需的第二驱动电流或电压与该第一驱动电流或电压的比例进行折算。然而，本申请并不限于此处陈述的折算方式。Wherein, the multiple sub-screens each have an initial brightness value during initial use, and the memory stores a mapping relationship between the cumulative use time of the sub-screen and the brightness attenuation value. Specifically, the foldable display device further includes a timer for separately counting the cumulative usage time of each sub-screen. The timer may be implemented by software or may be a specific hardware device. In another application example, the cumulative usage time is a theoretical usage time, and the theoretical usage time may be, for example, the actual usage time of the sub-screen under the brightness of the first driving current or voltage drive; when the display status of the sub-screen For content with higher contrast or higher brightness requirements, the theoretical duration of use is greater than the actual duration of use; otherwise, it is less than the actual duration of use. The specific conversion method can be converted, for example, by the ratio of the required second driving current or voltage to the first driving current or voltage. However, this application is not limited to the conversion methods stated here.
如上文提到的，仅对共显子屏幕进行亮度衰减的检测，用于下文将提到的亮度补偿，相对于对所有显示状态下的子屏幕进行亮度补偿而言，即保证了构成同一显示界面的亮度均匀性，也降低了补偿功耗。As mentioned above, only the co-display sub-screen is used for brightness attenuation detection, which is used for the brightness compensation mentioned below. Compared with the brightness compensation for all sub-screens in the display state, it is guaranteed to constitute the same display The brightness uniformity of the interface also reduces the compensation power consumption.
如图3所示，在一种实施方式中，步骤S101包括：As shown in FIG. 3, in one embodiment, step S101 includes:
步骤S201：统计该至少两个共显子屏幕对应的至少两个累计使用时长。Step S201: Count at least two cumulative usage durations corresponding to the at least two co-display sub-screens.
步骤S202：基于该映射关系和该至少两个累计使用时长，确定与该至少两个共显子屏幕对应的至少两个亮度衰减值。Step S202: Determine at least two brightness attenuation values corresponding to the at least two co-display sub-screens based on the mapping relationship and the at least two cumulative use durations.
如上文提到的，在其中一实施方式中，该累计使用时长为实际累计使用时长；而在另一实施方式中，该累计使用时长为理论使用时长。而上文提到的存储器所存储的映射关系，是通过对该可折叠装置的亮度衰减与累计使用时长的对应关系通过多次学习而获得的，从而获得最接近于实际情况的映射关系。As mentioned above, in one embodiment, the cumulative usage time is the actual cumulative usage time; and in another embodiment, the cumulative usage time is the theoretical usage time. The mapping relationship stored in the memory mentioned above is obtained through multiple studies of the correspondence between the brightness attenuation of the foldable device and the cumulative use time, so as to obtain the mapping relationship closest to the actual situation.
在一种实施方式中，每个子屏幕对应一个映射关系，根据各子屏幕的累计使用时长和映射关系计算出共显状态下的子屏幕的亮度衰减值。In one embodiment, each sub-screen corresponds to a mapping relationship, and the brightness attenuation value of the sub-screen in the co-display state is calculated according to the cumulative usage time of each sub-screen and the mapping relationship.
进一步地，该多个子屏幕的映射关系及初始亮度值分别相同。需要说明的是，该多个子屏幕的映射关系及初始亮度值也可以不同。Further, the mapping relationships and initial brightness values of the multiple sub-screens are the same. It should be noted that the mapping relationship and initial brightness values of the multiple sub-screens may also be different.
步骤S102：基于该至少两个亮度衰减值确定与该至少两个共显子屏幕对应 的至少两个亮度补偿值。Step S102: Determine at least two brightness compensation values corresponding to the at least two co-display sub-screens based on the at least two brightness attenuation values.
基于亮度衰减值确定亮度补偿值，在实现亮度均匀的前提下，选取可实现的亮度补偿值，提高了亮度补偿的可实现性。The brightness compensation value is determined based on the brightness attenuation value. On the premise of achieving uniform brightness, the achievable brightness compensation value is selected to improve the achievability of brightness compensation.
如图4所示，在一种实施方式中，步骤S102包括：As shown in FIG. 4, in one embodiment, step S102 includes:
步骤S301：基于该至少两个亮度衰减值确定一加权平均亮度衰减值，该加权平均亮度衰减值为该多个亮度衰减值的加权平均值。Step S301: Determine a weighted average brightness attenuation value based on the at least two brightness attenuation values, and the weighted average brightness attenuation value is a weighted average of the plurality of brightness attenuation values.
在一种实施方式中，至少两个亮度衰减值的权重相同，加权平均亮度衰减值为至少两个亮度衰减值的平均值。例如，处于共显状态下的子屏幕的数量为3个，3个亮度衰减值分别为30％L、20％L和10％L，其中L为初始亮度值，则计算出的加权平均亮度衰减值为20％L。In one embodiment, at least two luminance attenuation values have the same weight, and the weighted average luminance attenuation value is the average of at least two luminance attenuation values. For example, the number of sub-screens in the co-display state is 3, and the three brightness attenuation values are 30%L, 20%L, and 10%L, respectively, where L is the initial brightness value, then the calculated weighted average brightness attenuation The value is 20% L.
在其他实施方式中，至少两个亮度衰减值的权重也可以不同，例如，处于共显状态下的子屏幕的数量为3个，3个亮度衰减值和权重分别为30％L，45％、20％L，10％和10％L，45％，则此时亮度衰减值为：In other embodiments, the weights of at least two brightness attenuation values may also be different. For example, the number of sub-screens in a co-display state is three, and the three brightness attenuation values and weights are 30% L, 45%, 20%L, 10% and 10%L, 45%, then the brightness attenuation value is:
(30％L*45％+20％L*10％+10％L*45％)＝19％L。(30%L*45%+20%L*10%+10%L*45%)=19%L.
在一具体实施例中，该至少两个亮度衰减值的权重与该至少两个共显子屏幕的面积成正比；替换性地，该至少两个亮度衰减值的权重与初始使用时将该至少两个共显子屏幕设置为相同亮度时所需的驱动电流或驱动电压正成比。这样处理的有益效果在于，共显子屏幕越大，或者实现相同亮度所需的驱动电流或电压越大，则后续亮度补偿时，该共显子屏幕在相同的补偿值的前提下所需的驱动电流或电压亦越大，因此在计算亮度衰减时，需要更多地考虑屏幕更大或者在相同的补偿亮度的前提下所需的驱动电流或电压更大的共显子屏幕。In a specific embodiment, the weight of the at least two brightness attenuation values is proportional to the area of the at least two co-display sub-screens; alternatively, the weight of the at least two brightness attenuation values is The drive current or drive voltage required when the two co-display screens are set to the same brightness is proportional. The beneficial effect of this process is that the larger the co-display sub-screen, or the larger the drive current or voltage required to achieve the same brightness, then when the subsequent brightness compensation, the co-display sub-screen under the premise of the same compensation value The driving current or voltage is also larger, so when calculating the brightness attenuation, it is necessary to more consider the co-display sub-screen with a larger screen or a larger driving current or voltage under the premise of the same compensation brightness.
如上文所述，相对于未知亮度衰减值的情况下，即对各个共显子屏幕进行亮度补偿，上述实施例非常有效地将各个共显子屏幕的亮度补偿值进行差异化， 从而在后续步骤中，使得亮度补偿后的折叠显示装置的显示亮度更加均匀。As described above, relative to the case of unknown brightness attenuation value, that is, the brightness compensation of each co-display sub-screen, the above embodiment is very effective to differentiate the brightness compensation value of each co-display sub-screen, so that in the subsequent steps In the middle, the display brightness of the folded display device after brightness compensation is made more uniform.
此外，通过获取加权平均亮度衰减值，可以找到与各个共显子屏幕的当前亮度最接近的亮度；或者，在满足各个共显子屏幕的亮度相同或基本相同的前提下，最小化整体亮度补偿值，换言之，最小化亮度补偿所需的整体驱动电流或驱动电压。In addition, by obtaining the weighted average brightness attenuation value, the brightness closest to the current brightness of each co-display sub-screen can be found; or, on the premise that the brightness of each co-display sub-screen is the same or substantially the same, the overall brightness compensation is minimized The value, in other words, minimizes the overall drive current or drive voltage required for brightness compensation.
步骤S302：基于该加权平均亮度衰减值和该至少两个亮度衰减值，确定该至少两个共显子屏幕对应的至少两个亮度补偿值。Step S302: Based on the weighted average brightness attenuation value and the at least two brightness attenuation values, determine at least two brightness compensation values corresponding to the at least two co-display sub-screens.
例如，以权重完全相同为例，共显子屏幕的数量为3个，3个亮度衰减值分别为30％L、20％L和10％L，计算出的加权平均亮度衰减值为20％L，则该工显子屏幕的各子屏幕的亮度补偿值分别为10％、0和-10％。For example, taking the same weight as an example, the number of co-display sub-screens is 3, the three brightness attenuation values are 30%L, 20%L and 10%L, respectively, and the calculated weighted average brightness attenuation value is 20%L Then, the brightness compensation value of each sub-screen of the industrial display sub-screen is 10%, 0 and -10%, respectively.
步骤S103：根据该至少两个亮度补偿值，对该至少两个共显子屏幕分别进行亮度补偿，以使该至少两个共显子屏幕之间的亮度差异位于预设范围内。Step S103: Perform brightness compensation on the at least two co-display sub-screens respectively according to the at least two brightness compensation values, so that the brightness difference between the at least two co-display sub-screens is within a preset range.
在一种实施方式中，亮度补偿值包括至少两个共显子屏幕的驱动电压或者驱动电流的补偿值，驱动电压或者驱动电流用于驱动至少两个共显子屏幕进行亮度补偿；对该至少两个共显子屏幕分别进行亮度补偿包括：根据该驱动电压或者驱动电流的补偿值分别调整该至少两个共显子屏幕的驱动电压或者驱动电流，对该至少两个共显子屏幕分别进行亮度补偿。In one embodiment, the brightness compensation value includes the compensation value of the drive voltage or drive current of at least two co-display sub-screens, and the drive voltage or drive current is used to drive at least two co-display sub-screens for brightness compensation; The brightness compensation of the two co-display screens includes adjusting the drive voltage or drive current of the at least two co-display screens according to the compensation value of the drive voltage or drive current, respectively Brightness compensation.
上文提出的亮度补偿方法，通过检测共显状态下的至少两个共显子屏幕的至少两个亮度衰减值，确定出亮度补偿值，根据亮度补偿值对共显状态下的各子屏幕进行亮度补偿，保证可折叠显示装置共显状态下亮度的均匀性。The brightness compensation method proposed above determines the brightness compensation value by detecting at least two brightness attenuation values of at least two co-display sub-screens in the co-display state, and performs the sub-screens in the co-display state according to the brightness compensation value Brightness compensation to ensure the uniformity of brightness under the co-display state of the foldable display device.
如图5所示，本发明一实施例提供的亮度补偿方法包括：As shown in FIG. 5, the brightness compensation method provided by an embodiment of the present invention includes:
步骤S401：检测处于该共显状态下的至少两个共显子屏幕所对应的至少两个亮度衰减值，该至少两个共显子屏幕共同构成同一显示界面。Step S401: Detect at least two brightness attenuation values corresponding to at least two co-display sub-screens in the co-display state, and the at least two co-display sub-screens together constitute the same display interface.
步骤S402：基于该至少两个亮度衰减值确定与该至少两个共显子屏幕对应的至少两个亮度补偿值。Step S402: Determine at least two brightness compensation values corresponding to the at least two co-display sub-screens based on the at least two brightness attenuation values.
步骤S403：根据该至少两个亮度补偿值，对该至少两个共显子屏幕分别进行亮度补偿，以使该至少两个共显子屏幕之间的亮度差异位于预设范围内。Step S403: According to the at least two brightness compensation values, perform brightness compensation on the at least two co-display sub-screens respectively, so that the brightness difference between the at least two co-display sub-screens is within a preset range.
步骤S404：定期获取该多个子屏幕的累计使用时长。Step S404: Acquire the cumulative usage time of the multiple sub-screens regularly.
共显子屏幕使用过程中，记录使用时长，定期获取累计使用时长。即使用一定时间后，获取累计使用时长，根据累计使用时长重新计算共显子屏幕的亮度补偿值，以对共显子屏幕的亮度进行更精确的补偿，保证共显子屏幕亮度的均匀性。During the use of the co-display screen, record the duration of use and periodically obtain the cumulative duration of use. That is, after a certain period of time, the cumulative usage time is obtained, and the brightness compensation value of the co-display sub-screen is recalculated according to the cumulative usage time, so as to more accurately compensate the brightness of the co-display sub-screen and ensure the uniformity of the co-display sub-screen brightness.
如图6所示，本发明一实施例提供的亮度补偿方法，包括：As shown in FIG. 6, the brightness compensation method provided by an embodiment of the present invention includes:
步骤S501：判断该可折叠显示装置是否处于共显状态。Step S501: Determine whether the foldable display device is in a co-display state.
如图7所示，步骤S501包括：As shown in FIG. 7, step S501 includes:
步骤S601：检测每个相邻的该折弯部和该非折弯部之间的夹角角度。Step S601: Detect the angle between each adjacent bending part and the non-bending part.
步骤S602：若至少一个该夹角角度在预设角度范围内，则判断该可折叠显示装置处于共显状态。Step S602: If at least one of the included angles is within a preset angle range, it is determined that the foldable display device is in a co-display state.
例如，设定可折叠显示装置中处于同一平面的各子屏幕为处于共显状态下的子屏幕。当有一个相邻的折弯部和非折弯部之间的夹角角度为180度时，则判定可折叠显示装置处于共显状态。然而，由于在用户使用该可折叠显示装置时，用户可能未将该可折叠显示装置完全展平，或者由于可折叠显示装置未能完全展开，但是此时折弯部和非折弯部之间的夹角满足可以构成同一个显示界面，换言之，该角度为用户可接受弯折角度，则亦判断该可折叠显示装置处于共显状态。在一具体实施例中，该预设角度范围为-30°～30°，在另一实施例中，该预设角度范围为-10°～10°或-15°～15°。For example, each sub-screen on the same plane in the foldable display device is set as a sub-screen in a co-display state. When the angle between one adjacent bending part and the non-bending part is 180 degrees, it is determined that the foldable display device is in the co-display state. However, because when the user uses the foldable display device, the user may not fully flatten the foldable display device, or because the foldable display device fails to fully unfold, but at this time between the bent portion and the non-bent portion If the included angle satisfies, the same display interface can be formed. In other words, the angle is the acceptable bending angle of the user, and the foldable display device is also judged to be in the co-display state. In a specific embodiment, the preset angle range is -30°-30°, and in another embodiment, the preset angle range is -10°-10° or -15°-15°.
步骤S502：检测处于该共显状态下的至少两个共显子屏幕所对应的至少两个亮度衰减值。Step S502: Detect at least two brightness attenuation values corresponding to at least two co-display sub-screens in the co-display state.
步骤S503：基于该至少两个亮度衰减值确定与该至少两个共显子屏幕对应的至少两个亮度补偿值。Step S503: Determine at least two brightness compensation values corresponding to the at least two co-display sub-screens based on the at least two brightness attenuation values.
步骤S504：根据该至少两个亮度补偿值，对该至少两个共显子屏幕分别进行亮度补偿，以使该至少两个共显子屏幕之间的亮度差异位于预设范围内。Step S504: Perform brightness compensation on the at least two co-display sub-screens respectively according to the at least two brightness compensation values, so that the difference in brightness between the at least two co-display sub-screens is within a preset range.
如图8所示，在本发明另一实施方式中，在对该至少两个共显子屏幕分别进行亮度补偿之前还包括：As shown in FIG. 8, in another embodiment of the present invention, before performing brightness compensation on the at least two co-display sub-screens, the method further includes:
步骤S701：根据该至少两个亮度衰减值，判断该至少两个亮度衰减值中的最大值和最小值的差值的绝对值是否在大于预设阈值。Step S701: According to the at least two brightness attenuation values, determine whether the absolute value of the difference between the maximum value and the minimum value of the at least two brightness attenuation values is greater than a preset threshold.
步骤S702：若该至少两个亮度衰减值中的最大值和最小值的差值的绝对值大于预设阈值，则执行根据该至少两个亮度补偿值对该至少两个共显子屏幕分别进行亮度补偿。Step S702: If the absolute value of the difference between the maximum value and the minimum value of the at least two brightness attenuation values is greater than a preset threshold, perform at least two common display sub-screens according to the at least two brightness compensation values Brightness compensation.
具体的，共显状态下，若该至少两个亮度衰减值的差异较小，不足以影响共显子屏幕的均匀性，则可以不对共显子屏幕进行亮度补偿，若共显子屏幕的亮度衰减值之间的差异较大，则对共显子屏幕分别进行亮度补偿。Specifically, in the co-display state, if the difference between the at least two brightness attenuation values is small and insufficient to affect the uniformity of the co-display sub-screen, the brightness compensation of the co-display sub-screen may not be performed. If the difference between the attenuation values is large, the brightness of the co-display sub-screens are compensated separately.
例如，设定预设阈值为5％L，若3个共显子屏幕的亮度衰减值分别为10％L、12％L和13％L，则不对共显子屏幕进行亮度补偿。若3个共显子屏幕的亮度衰减值分别为10％L、15％L和20％L，则对共显子屏幕进行亮度补偿。For example, the preset threshold is set to 5% L, and if the brightness attenuation values of the three co-display sub-screens are 10% L, 12% L, and 13% L, respectively, no brightness compensation is performed on the co-display sub-screen. If the brightness attenuation values of the three co-display sub-screens are 10% L, 15% L, and 20% L, respectively, the brightness compensation is performed on the co-display sub-screen.
如图9所示，还提供一种可折叠显示装置，包括多个子屏幕13、处理器14和存储器15，存储器15中存储有计算机可读程序，计算机可读程序被处理器14执行时实现本发明一些实施例提供的亮度补偿方法，以保证可折叠显示装置展开时亮度的均匀性。该计算机可读程序被处理器执行时实现下述步骤：As shown in FIG. 9, a foldable display device is also provided, which includes a plurality of sub-screens 13, a processor 14, and a memory 15, the memory 15 stores a computer-readable program, which is implemented when the computer-readable program is executed by the processor 14.

进一步地，该可折叠显示装置包括存储有子屏幕的累计使用时长与亮度衰减值的映射关系的存储器；该计算机可读程序被该处理器执行时还实现：Further, the foldable display device includes a memory that stores a mapping relationship between the cumulative usage time of the sub-screen and the brightness attenuation value; when the computer-readable program is executed by the processor, it is also implemented:

基于该映射关系和该至少两个累计使用时长，确定与该至少两个共显子屏幕对应的至少两个亮度衰减值。Based on the mapping relationship and the at least two cumulative usage durations, at least two brightness attenuation values corresponding to the at least two co-display sub-screens are determined.
进一步地，该多个子屏幕的该映射关系及该初始亮度值分别相同。Further, the mapping relationship and the initial brightness value of the multiple sub-screens are respectively the same.
进一步地，该计算机可读程序被该处理器执行时还实现：Further, when the computer-readable program is executed by the processor, it is also implemented:
基于该至少两个亮度衰减值确定一加权平均亮度衰减值，该加权平均亮度衰减值为该多个亮度衰减值的加权平均值；Determining a weighted average brightness attenuation value based on the at least two brightness attenuation values, the weighted average brightness attenuation value being a weighted average of the plurality of brightness attenuation values;
基于该加权平均亮度衰减值和该至少两个亮度衰减值，确定该至少两个共显子屏幕对应的至少两个亮度补偿值。Based on the weighted average brightness attenuation value and the at least two brightness attenuation values, at least two brightness compensation values corresponding to the at least two co-display sub-screens are determined.
