具体实施方式Detailed ways
在下文中，仅简单地描述了某些示例性实施例。正如本领域技术人员可认识到的那样，在不脱离本公开的精神或范围的情况下，可通过各种不同方式修改所描述的实施例。因此，附图和描述被认为本质上是示例性的而非限制性的。In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present disclosure. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.
图1是本公开一实施例的OLED器件的发光电路图。如图1所示，该发光电路包括第一晶体管T1、第二晶体管T2和第三晶体管DT。第三晶体管DT为OLED器件。流经OLED器件的电流受控于g、s两个节点的电压Vgs。当G1打开第一晶体管T1，将数据电压Vdata写入g节点，从而，g节点电压Vg＝Vdata。随着OLED器件随发光时间的老化，OLED器件的发光效率会衰减，显示亮度也随之降低。因此，对OLED器件进行光老化补偿的目的是为了解决OLED器件老化的问题，延长OLED显示面板的正常使用寿命。FIG. 1 is a light emitting circuit diagram of an OLED device according to an embodiment of the present disclosure. As shown in FIG. 1 , the lighting circuit includes a first transistor T1 , a second transistor T2 and a third transistor DT. The third transistor DT is an OLED device. The current flowing through the OLED device is controlled by the voltage Vgs of the two nodes of g and s. When G1 turns on the first transistor T1, the data voltage Vdata is written into the g node, so the g node voltage Vg=Vdata. As the OLED device ages with the luminous time, the luminous efficiency of the OLED device will decay, and the display brightness will also decrease accordingly. Therefore, the purpose of performing light aging compensation on the OLED device is to solve the aging problem of the OLED device and prolong the normal service life of the OLED display panel.
对OLED器件进行光补偿的原理是：对数据电压Vdata增加一个增量电压Δv，从而增加OLED器件的电流I，提高OLED器件的发光功率，以提高OLED器件的亮度。从而达到对OLED器件进行亮度补偿。The principle of performing light compensation on the OLED device is: adding an incremental voltage Δv to the data voltage Vdata, thereby increasing the current I of the OLED device, increasing the luminous power of the OLED device, and increasing the brightness of the OLED device. In this way, the brightness compensation of the OLED device is achieved.
对于如何确定OLED器件的亮度补偿值，一般的方案是：对OLED器件的亮度分级再累积亮度衰减值，根据累积亮度衰减值与亮度补偿值之间的映射关系，确定目标亮度补偿值，然后再根据目标亮度补偿值对电路中的数据电压Vdata增加一个对应的增量电压Δv，从而实现OLED器件的光补偿。For how to determine the brightness compensation value of the OLED device, the general solution is: classify the brightness of the OLED device and then accumulate the brightness attenuation value, determine the target brightness compensation value according to the mapping relationship between the accumulated brightness attenuation value and the brightness compensation value, and then A corresponding incremental voltage Δv is added to the data voltage Vdata in the circuit according to the target brightness compensation value, so as to realize light compensation of the OLED device.
本公开实施例提供的光补偿方法除了应用于上述OLED器件之外，还可以应用于其他发光器件。例如，量子点发光二极管(Quantum Dot Light Emitting Diodes，简称QLED)或微发光二极管(Micro Light Emitting Diodes，简称Micro LED)等。The light compensation method provided by the embodiments of the present disclosure can be applied to other light-emitting devices in addition to the above-mentioned OLED device. For example, Quantum Dot Light Emitting Diodes (Quantum Dot Light Emitting Diodes, QLED for short) or Micro Light Emitting Diodes (Micro Light Emitting Diodes, Micro LED for short).
图2是本公开一实施例的光亮度补偿方法的流程图。如图2所示，该方法可以包括：FIG. 2 is a flowchart of a brightness compensation method according to an embodiment of the disclosure. As shown in Figure 2, the method may include:
S210，基于显示面板的初始显示亮度对应的亮度衰减曲线，确定显示面板在经过衰减时间的亮度衰减后所得到的预测显示亮度；S210, based on the luminance decay curve corresponding to the initial display luminance of the display panel, determine the predicted display luminance obtained by the display panel after the luminance decay of the decay time;
S220，基于显示面板的衰减时间确定累计衰减时间；S220. Determine the cumulative decay time based on the decay time of the display panel;
S230，基于预测显示亮度更新初始显示亮度；S230, updating the initial display brightness based on the predicted display brightness;
S240，基于更新后的初始显示亮度更新衰减时间；S240, updating the decay time based on the updated initial display brightness;
S250，重复执行上述步骤S210至S240，直至累计衰减时间达到设定的时间阈值时，基于当前的预测显示亮度，确定显示面板的亮度补偿值。S250, repeatedly execute the above steps S210 to S240, until the accumulated decay time reaches the set time threshold, determine the brightness compensation value of the display panel based on the current predicted display brightness.
在本示例中，通过确定显示面板的初始亮度，并逐个衰减时间地确定对应的亮度衰减曲线以及经过该衰减时间的亮度衰减后的预测亮度，并在衰减累计时间达到设定的时间阈值，则基于最后预测得到的亮度进行亮度补偿，能够减少亮度补偿的累计误差，提高亮度补偿的精度。In this example, by determining the initial luminance of the display panel, and determining the corresponding luminance decay curve and the predicted luminance after the luminance decay of the decay time, and the cumulative decay time reaches the set time threshold, then Performing brightness compensation based on the finally predicted brightness can reduce the cumulative error of brightness compensation and improve the accuracy of brightness compensation.
示例性地，上述方法除了应用于显示面板也可以应用于OLED灯或者其他发光器件的亮度补偿，并不局限于显示面板。这可以根据实际需要进行选择设备。发光器件可以包括OLED器件、QLED器件、LED器件等。Exemplarily, the above method can also be applied to brightness compensation of OLED lamps or other light-emitting devices in addition to being applied to display panels, and is not limited to display panels. This can be selected according to actual needs. Light emitting devices may include OLED devices, QLED devices, LED devices, and the like.
示例性地，在上述步骤S210之前，在显示面板开始显示时，检测显示面板的显示亮度，将其为初始显示亮度。也可以是在显示面板的当前显示亮度满足亮度补偿条件的情况下，以显示面板的当前显示亮度作为初始显示亮度，然后开始进行亮度补偿。显示面板满足亮度补偿条件可以为，当前显示亮度低于设定的亮度阈值，或者在设定时间段内显示面板的亮度衰减量达到设定的亮度衰减量阈值。Exemplarily, before the above step S210, when the display panel starts to display, the display brightness of the display panel is detected and used as the initial display brightness. Alternatively, when the current display brightness of the display panel satisfies the brightness compensation condition, the current display brightness of the display panel is used as the initial display brightness, and then brightness compensation is started. The condition for the display panel to meet the brightness compensation may be that the current display brightness is lower than a set brightness threshold, or the brightness attenuation of the display panel reaches the set brightness attenuation threshold within a set time period.
示例性地，在上述步骤S210之前，可以基于显示面板的初始显示亮度，确定衰减时间。或者，可以基于显示面板的初始显示亮度对应的亮度等级，确定对应的衰减时间。例如，如果初始显示亮度对应的亮度等级为L1，对应的衰减时间为t1。如果初始显示亮度对应的亮度等级为L2，对应的衰减时间为t2。Exemplarily, before the above step S210, the decay time may be determined based on the initial display brightness of the display panel. Alternatively, the corresponding decay time may be determined based on the brightness level corresponding to the initial display brightness of the display panel. For example, if the brightness level corresponding to the initial display brightness is L1, the corresponding decay time is t1. If the brightness level corresponding to the initial display brightness is L2, the corresponding decay time is t2.
示例性地，上述衰减时间也可以基于上述设定的时间阈值进行确定，例如划分成多个相同的衰减时间或者不相同的衰减时间。Exemplarily, the above-mentioned decay time may also be determined based on the above-set time threshold, for example, divided into multiple same or different decay times.
示例性地，亮度衰减曲线可以包括显示亮度随时间变化的曲线，显示亮度衰减率(显示亮度衰减率)随时间变化的曲线。Exemplarily, the brightness attenuation curve may include a curve showing changes in brightness with time, and a curve showing changes in brightness attenuation rate (displaying brightness attenuation rate) with time.
示例性地，不同的初始显示亮度对应不同的亮度衰减曲线。例如，确定初始显示亮度所在亮度区间，确定该亮度区间对应的亮度衰减曲线。在绘制亮度衰减曲线时，则按照不同的亮度区间分别进行绘制。再如，确定初始显示亮度所在的亮度级别，确定该亮度级别对应的亮度衰减曲线。在绘制亮度衰减曲线时，则按照不同的亮度级别分别进行绘制。Exemplarily, different initial display brightnesses correspond to different brightness decay curves. For example, the brightness interval where the initial display brightness is located is determined, and the brightness attenuation curve corresponding to the brightness interval is determined. When drawing the brightness attenuation curve, it is drawn separately according to different brightness intervals. For another example, the brightness level at which the initial display brightness is located is determined, and the brightness decay curve corresponding to the brightness level is determined. When drawing the brightness attenuation curve, it is drawn separately according to different brightness levels.
示例性地，在上述步骤S220中，显示面板的初始累计衰减时间可以置零，也可以是一个固定的非零时间。然后，每执行一次步骤S210，则将衰减时间累计到累计衰减时间中。Exemplarily, in the above step S220, the initial cumulative decay time of the display panel may be set to zero, or may be a fixed non-zero time. Then, each time step S210 is executed, the decay time is accumulated into the cumulative decay time.
例如，初始累计衰减时间为0，第一次执行步骤S210时的衰减时间为10分钟，则将累计衰减时间更新为10分钟。第二次执行步骤S210的衰减时间为20分钟，则将本次的衰减时间20分钟累计到累计衰减时间10分钟中，得到更新后的累计衰减时间为30分钟。For example, the initial cumulative decay time is 0, and the decay time when step S210 is executed for the first time is 10 minutes, then the cumulative decay time is updated to 10 minutes. The decay time of the second execution of step S210 is 20 minutes, and the current decay time of 20 minutes is accumulated into the cumulative decay time of 10 minutes, and the updated cumulative decay time is 30 minutes.
示例性地，在上述步骤S240中，基于更新后的初始显示亮度对应的亮度等级，确定对应的衰减时间。例如，如果初始显示亮度对应的亮度等级更新为L1，则衰减时间更新为t1。如果初始显示亮度对应的亮度等级更新为L2，衰减时间更新为t2。Exemplarily, in the above step S240, the corresponding decay time is determined based on the brightness level corresponding to the updated initial display brightness. For example, if the brightness level corresponding to the initial display brightness is updated to L1, the decay time is updated to t1. If the brightness level corresponding to the initial display brightness is updated to L2, the decay time is updated to t2.
在一些可能的实现方式中，亮度衰减曲线可以按照亮度等级进行绘制。在确定亮度补偿值时，根据初始显示亮度对应的亮度等级来确定对应的亮度衰减曲线。然后，基于亮度衰减曲线进行衰减预测，得到预测显示亮度。In some possible implementation manners, the brightness attenuation curve may be drawn according to brightness levels. When determining the brightness compensation value, the corresponding brightness attenuation curve is determined according to the brightness level corresponding to the initial display brightness. Then, attenuation prediction is performed based on the brightness attenuation curve to obtain predicted display brightness.
示例性地，上述基于初始显示亮度对应的亮度衰减曲线以及衰减时间，确定显示面板在经过衰减时间的亮度衰减后所得到的预测显示亮度，可以包括：Exemplarily, the determination of the predicted display brightness obtained by the display panel after the brightness decay of the decay time based on the brightness decay curve corresponding to the initial display brightness and the decay time may include:
基于初始显示亮度对应的亮度等级，确定对应的亮度衰减曲线；Determine a corresponding brightness decay curve based on the brightness level corresponding to the initial display brightness;
基于初始显示亮度、亮度衰减曲线以及衰减时间，确定显示面板的预测显示亮度。A predicted display brightness of the display panel is determined based on the initial display brightness, the brightness decay curve, and the decay time.
在本示例中，在设定的时间阈值内，每段衰减时间采用不同亮度衰减曲线来预测显示面板的预测显示亮度，且该亮度衰减曲线与该段衰减时间的起始初始显示亮度所对应的亮度等级对应，这样可以减少预测亮度的累计误差，从而提高显示面板的亮度补偿精度。In this example, within the set time threshold, each decay time uses a different brightness decay curve to predict the predicted display brightness of the display panel, and the brightness decay curve corresponds to the initial display brightness of the decay time. The luminance level corresponds, which can reduce the cumulative error of the predicted luminance, thereby improving the brightness compensation accuracy of the display panel.
在一些可能的实现方式中，亮度衰减曲线为随时间变化的亮度衰减比值曲线。亮度衰减比值曲线的X轴为时间，Y轴为亮度衰减比值。不同的亮度等级对应不同的亮度衰减比值曲线。In some possible implementation manners, the brightness attenuation curve is a time-varying brightness attenuation ratio curve. The X-axis of the brightness attenuation ratio curve is time, and the Y-axis is the brightness attenuation ratio. Different brightness levels correspond to different brightness attenuation ratio curves.
示例性地，上述基于初始显示亮度、亮度衰减曲线以及衰减时间，确定显示面板的预测显示亮度，可以包括：Exemplarily, the determination of the predicted display brightness of the display panel based on the initial display brightness, the brightness decay curve, and the decay time may include:
确定起点亮度衰减比值；Determine the brightness attenuation ratio of the starting point;
基于起点亮度衰减比值以及衰减时间，在亮度衰减比值曲线中确定终点亮度衰减比值；Based on the brightness attenuation ratio of the starting point and the decay time, determine the brightness attenuation ratio of the end point in the brightness attenuation ratio curve;
基于终点亮度衰减比值与起点亮度衰减比值之间的差值，以及初始显示亮度，确定显示面板的预测显示亮度。Based on the difference between the end point brightness attenuation ratio and the starting point brightness attenuation ratio, and the initial display brightness, the predicted display brightness of the display panel is determined.
在本示例中，基于起点亮度衰减比值以及衰减时间，在亮度衰减比值曲线中确定终点亮度衰减比值，基于终点亮度衰减比值与起点亮度衰减比值之间的差值，得到显示面板在这个衰减时间的衰减量，再将衰减量与初始显示亮度相乘，初始显示亮度减去该乘积，从而，可以得到显示面板从初始显示亮度开始衰减亮度并经过该衰减时间之后的预测显示亮度。In this example, based on the brightness attenuation ratio at the starting point and the decay time, the brightness attenuation ratio at the end point is determined in the brightness attenuation ratio curve. The attenuation amount is multiplied by the initial display brightness and the initial display brightness is subtracted from the product, so that the predicted display brightness of the display panel after the decay time from the initial display brightness can be obtained.
示例性地，起始亮度衰减比值为70％，经过衰减时间t1之后，从亮度衰减比值曲线中可知，终点亮度衰比值为60％。则计算得到显示面板在衰减时间t1的衰减量10％。假设初始显示亮度为90，则预测显示亮度为：90-(90*10％)＝81。Exemplarily, the initial brightness attenuation ratio is 70%, and after the decay time t1, it can be seen from the brightness attenuation ratio curve that the terminal brightness attenuation ratio is 60%. Then the attenuation of the display panel at the attenuation time t1 is calculated to be 10%. Assuming that the initial display brightness is 90, the predicted display brightness is: 90-(90*10%)=81.
在一些可能的实现方式中，上述确定起点亮度衰减比值，可以包括：在累计衰减时间为0的情况下，起点亮度衰减比值为1。In some possible implementation manners, the determination of the starting point brightness attenuation ratio may include: when the accumulated decay time is 0, the starting point brightness attenuation ratio is 1.
在本示例中，在第一次执行步骤S210时，第一次得到的亮度衰减比值曲线的起点亮度衰减比值为1。In this example, when step S210 is executed for the first time, the brightness attenuation ratio at the starting point of the brightness attenuation ratio curve obtained for the first time is 1.
在一些可能的实现方式中，上述确定起点亮度衰减比值，可以包括：在累计衰减时间未达到上述时间阈值且得到终点亮度衰减比值的情况下，基于终点亮度衰减比值更新起点亮度衰比值。In some possible implementation manners, the determination of the starting point brightness attenuation ratio may include: updating the starting point brightness attenuation ratio based on the ending point brightness attenuation ratio when the accumulated decay time does not reach the above time threshold and the end point brightness attenuation ratio is obtained.
在本示例性中，在累计衰减时间未达到上述时间阈值时，将上一次确定显示面板的预测显示亮度时所确定终点亮度衰减比值，作为下一次计算显示面板的预测显示亮度时的起点亮度衰比值。从而可以不断地累计衰减比值，避免出现预测误差。In this example, when the cumulative attenuation time does not reach the above time threshold, the end-point luminance attenuation ratio determined when the predicted display brightness of the display panel was determined last time is used as the starting point luminance attenuation ratio for the next calculation of the predicted display brightness of the display panel. ratio. Therefore, the attenuation ratio can be continuously accumulated to avoid prediction errors.
在一些可能的实现方式中，方法还包括：In some possible implementations, the method also includes:
基于显示面板的亮度补偿值，对显示面板进行亮度补偿；performing brightness compensation on the display panel based on the brightness compensation value of the display panel;
在针对显示面板进行亮度补偿之后，检测显示面板的当前显示亮度；After brightness compensation is performed on the display panel, the current display brightness of the display panel is detected;
将显示面板的当前显示亮度作为初始显示亮度，并重新计算显示面板的亮度补偿值，以继续对显示面板进行亮度补偿。Taking the current display brightness of the display panel as the initial display brightness, and recalculating the brightness compensation value of the display panel, so as to continue to perform brightness compensation on the display panel.
在本示例中，在每一次进行亮度补偿后，利用检测到的显示面板的当前显示亮度作为预测显示面板在未来显示时间内衰减的初始显示亮度，可以准确地计算在未来显示时间内亮度补偿值，提高下一次亮度补偿的精度。In this example, after each brightness compensation, the detected current display brightness of the display panel is used as the predicted initial display brightness of the display panel to decay in the future display time, and the brightness compensation value in the future display time can be accurately calculated , to improve the accuracy of the next brightness compensation.
在一些可能的实现方式中，还可以按照不同的亮度等级，绘制显示面板的亮度衰减曲线。示例性地，上述方法还可以包括：In some possible implementation manners, brightness attenuation curves of the display panel may also be drawn according to different brightness levels. Exemplarily, the above method may also include:
按照所述初始显示亮度对应的亮度等级，控制所述显示面板开始显示；controlling the display panel to start displaying according to the brightness level corresponding to the initial display brightness;
在显示面板中预设的多个测试位置中，按照设定的检测频率，检测多个测试位置中的每个测试位置的显示亮度，得到多个时间点各自对应的显示亮度；In the plurality of test positions preset in the display panel, according to the set detection frequency, the display brightness of each test position in the plurality of test positions is detected, and the display brightness corresponding to each of the plurality of time points is obtained;
根据多个时间点各自对应的显示亮度，确定初始显示亮度对应的亮度衰减曲线。A brightness decay curve corresponding to the initial display brightness is determined according to the display brightness corresponding to each of the multiple time points.
在本示例性中，可以预先绘制出初始显示亮度对应的亮度衰减曲线，方便后续在进行亮度补偿时调取出来使用。In this example, the brightness attenuation curve corresponding to the initial display brightness can be drawn in advance, so that it can be retrieved and used later when brightness compensation is performed.
示例性地，也可以直接为显示面板的显示亮度设置不同等级的亮度级别，然后按照各亮度级别对应的平均亮度，控制显示面板开始显示。并按照上述测试步骤进行测试，可以得到每个亮度级别对应的亮度衰减曲线。Exemplarily, it is also possible to directly set different brightness levels for the display brightness of the display panel, and then control the display panel to start displaying according to the average brightness corresponding to each brightness level. And test according to the above test steps, you can get the brightness attenuation curve corresponding to each brightness level.
示例性地，测试位置可以根据需要进行设置。例如将显示面板划分为多个区域，每个区域作为一个测试位置。例如，如图3所示，将显示面板划分为9个区域，对每个区域的中心位置进行显示亮度的检测。Exemplarily, the test location can be set as required. For example, the display panel is divided into multiple areas, and each area is used as a test location. For example, as shown in FIG. 3 , the display panel is divided into 9 regions, and the display brightness is detected for the central position of each region.
示例性地，检测频率可以根据进行设备。例如，每隔10分钟或者20分钟测量一次。Exemplarily, the detection frequency may be based on the performing device. For example, measure every 10 minutes or 20 minutes.
示例性地，为了提高绘制效率，在上述得到多个时间点各自对的显示亮度时，按时间顺序对显示亮度进行排序，然后利用插值法，插入多个显示亮度，从而基于插值之后得到的所有显示亮度，绘制亮度衰减曲线。Exemplarily, in order to improve drawing efficiency, when obtaining the display luminances of respective pairs at multiple time points, sort the display luminances in time order, and then use interpolation to interpolate multiple display luminances, so that based on all Display brightness and draw brightness decay curve.
