Description

一种发光元件的亮度确定方法、装置及移动终端Method, device and mobile terminal for determining brightness of light-emitting element

技术领域technical field

背景技术Background technique

目前,有机发光二极管(OrganicLight-EmittingDiode,简称为“OLED”)作为平面显示器新兴应用技术,由于具有自发光特性,不需背光源,能够节省电能,可视角度大等优势,已在手机、数码摄像机、平板电脑及电视机等终端中得到广泛应用。At present, Organic Light-Emitting Diode (Organic Light-Emitting Diode, referred to as "OLED") is an emerging application technology of flat-panel displays. It is widely used in terminals such as cameras, tablet PCs and TVs.

由于OLED是自发光的,其发光过程就是OLED材料不断消耗的过程。因此,随着时间的推移,OLED材料会发生老化,如其发光度会逐渐降低,并会产生色差。为确保用户体验,提升OLED显示效果,则需要检测出发生老化的OLED以对该发生老化的OLED进行老化补偿。目前一般是直接根据光传感器测量出终端显示屏的亮度值来确定OLED是否发生老化,然而,在通过显示屏进行内容显示时,测量出的亮度值不仅包括OLED发光亮度,往往还与当前环境亮度有关,导致老化检测准确性较低。Since OLED is self-luminous, its light-emitting process is the process of continuous consumption of OLED materials. Therefore, as time goes by, the OLED material will age, such as its luminosity will gradually decrease, and chromatic aberration will occur. In order to ensure the user experience and improve the display effect of the OLED, it is necessary to detect the aged OLED to perform aging compensation for the aged OLED. At present, it is generally determined whether the OLED is aging directly based on the brightness value of the terminal display screen measured by the light sensor. However, when the content is displayed through the display screen, the measured brightness value not only includes the OLED luminance, but also often differs from the current ambient brightness. related, resulting in lower accuracy of aging detection.

Each will be described in detail below.

请参阅图1,图1是本发明实施例提供的一种发光元件的亮度确定方法的流程示意图。具体的,如图1所示,本发明实施例的所述发光元件的亮度确定方法可以包括以下步骤:Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of a method for determining brightness of a light-emitting element provided by an embodiment of the present invention. Specifically, as shown in FIG. 1, the method for determining the brightness of the light-emitting element in the embodiment of the present invention may include the following steps:

101、当移动终端的显示屏包括的发光元件发光时,获取所述发光元件发光时所述显示屏的第一亮度。101. When a light emitting element included in a display screen of a mobile terminal emits light, acquire a first brightness of the display screen when the light emitting element emits light.

应理解,本发明实施例的所述方法可具体应用于上述的移动终端(简称“终端”)中,该终端的显示屏由至少一个发光元件组成。进一步的,该发光元件与屏幕像素相对应,具体可以为OLED。每一个所述屏幕像素包括红色子像素点(R)、绿色子像素点(G)以及蓝色子像素点(B),则该屏幕像素中的每一个子像素点即可为一个OLED,该红色子像素点(R)对应的OLED用于显示红色(发红光)、绿色子像素点(G)对应的OLED用于显示绿色(发绿光),蓝色子像素点(B)对应的OLED用于显示蓝色(发蓝光),从而通过RGB进行混色显示。It should be understood that the method in the embodiment of the present invention can be specifically applied to the above-mentioned mobile terminal ("terminal" for short), and the display screen of the terminal is composed of at least one light-emitting element. Further, the light-emitting element corresponds to the pixels of the screen, specifically, it may be an OLED. Each of the screen pixels includes red sub-pixels (R), green sub-pixels (G) and blue sub-pixels (B), then each sub-pixel in the screen pixels can be an OLED, the The OLED corresponding to the red sub-pixel (R) is used to display red (emits red light), the OLED corresponding to the green sub-pixel (G) is used to display green (emit green light), and the OLED corresponding to the blue sub-pixel (B) OLED is used to display blue (emits blue light), thus performing color mixing display through RGB.

具体实施例中,一般情况下,在点亮OLED,即通过显示屏(具体可以是终端显示屏中的某一特定显示区域)包括的发光元件进行发光时,检测到的显示区域的亮度(即第一亮度)往往包括发光元件的发光亮度,还包括受当前环境光影响反射的部分环境光的亮度。由此,将发光元件发光时检测到的亮度值直接作为该发光元件的发光亮度并不准确。具体的,该发光元件发光时显示屏对应的亮度值即第一亮度可通过预置的光感器件如光传感器测量得到。In a specific embodiment, in general, when the OLED is turned on, that is, when the light-emitting elements included in the display screen (specifically, a specific display area in the terminal display screen) emit light, the detected brightness of the display area (i.e. The first brightness) often includes the luminous brightness of the light-emitting element, and also includes the brightness of part of the ambient light reflected by the current ambient light. Therefore, it is not accurate to directly use the luminance value detected when the light-emitting element emits light as the light-emitting luminance of the light-emitting element. Specifically, when the light-emitting element emits light, the corresponding brightness value of the display screen, ie, the first brightness, can be measured by a preset light-sensing device such as a light sensor.

102、控制所述发光元件停止发光,并获取所述发光元件停止发光时所述显示屏的第二亮度。102. Control the light emitting element to stop emitting light, and acquire a second brightness of the display screen when the light emitting element stops emitting light.

其中,该发光元件停止发光时显示屏对应的亮度值即第二亮度同样可通过预置的该光传感器测量得到。Wherein, the brightness value corresponding to the display screen when the light-emitting element stops emitting light, ie, the second brightness, can also be measured by the preset light sensor.

进一步的,在获取得到发光元件发光时显示区域的第一亮度之后,即可控制该显示区域的发光元件停止发光,并获取得到此时该显示区域对应的亮度值即第二亮度。由于该步骤下显示区域的发光元件并未发光,则该获取得到的第二亮度可作为当前环境光折射的亮度值。Further, after obtaining the first brightness of the display area when the light-emitting element emits light, the light-emitting element in the display area can be controlled to stop emitting light, and the brightness value corresponding to the display area at this time, that is, the second brightness can be obtained. Since the light-emitting elements in the display area do not emit light in this step, the obtained second brightness can be used as the brightness value of the current ambient light refraction.

103、根据所述第一亮度和所述第二亮度,计算得到所述发光元件的发光亮度,以根据所述发光亮度对所述发光元件进行老化补偿。103. According to the first brightness and the second brightness, calculate the light emitting brightness of the light emitting element, so as to perform aging compensation on the light emitting element according to the light emitting brightness.

在获取得到显示屏中发光元件发光时的第一亮度及不发光时的第二亮度之后,即可按照预设的算法过滤环境光的影响,计算出该显示屏中发光元件的实际发光亮度,比如将该第一亮度减去第二亮度的差值作为该显示屏的发光元件的实际发光亮度,从而能够根据该发光元件的实际发光亮度判断其是否发生老化,以在确定发生老化时及时地对发生老化的发光元件进行补偿。具体的,可预先存储一个亮度基准值,从而可通过将该发光元件的实际发光亮度与该亮度基准值进行比较,并在该实际发光亮度低于该亮度基准值时确定该发光元件发生老化。其中,该亮度基准值可以是终端出厂时屏幕点亮后自动获取并存储的,或者由终端设计人员预先配置的,本发明实施例不做限定。After obtaining the first brightness when the light-emitting element in the display screen emits light and the second brightness when it does not emit light, the influence of ambient light can be filtered according to a preset algorithm, and the actual light-emitting brightness of the light-emitting element in the display screen can be calculated. For example, the difference between the first luminance minus the second luminance is used as the actual luminous brightness of the light-emitting element of the display screen, so that it can be judged according to the actual luminous brightness of the light-emitting element whether it is aging, so that when it is determined that aging occurs, timely Compensation for aging light-emitting elements. Specifically, a brightness reference value may be stored in advance, so that the actual luminous brightness of the light-emitting element can be compared with the brightness reference value, and when the actual luminous brightness is lower than the brightness reference value, it can be determined that the light-emitting element is aging. Wherein, the brightness reference value may be automatically obtained and stored after the screen of the terminal is turned on when the terminal leaves the factory, or may be preconfigured by a terminal designer, which is not limited in this embodiment of the present invention.

在本发明实施例中,可通过在移动终端的显示屏包括的发光元件发光时获取发光元件发光时该显示屏对应的第一亮度,并通过控制发光元件停止发光,获取发光元件停止发光时该显示屏对应的第二亮度,从而能够根据该第一亮度和第二亮度计算得到发光元件的实际发光亮度,而过滤掉环境光的影响,以根据计算出的实际发光亮度确定该发光元件是否发生老化,从而在发生老化时及时地对该发光元件进行老化补偿,提升了老化检测的准确性。In the embodiment of the present invention, the first brightness corresponding to the display screen when the light-emitting element is light-emitting can be obtained when the light-emitting element included in the display screen of the mobile terminal emits light, and by controlling the light-emitting element to stop emitting light, the first brightness when the light-emitting element stops emitting light can be obtained. The second brightness corresponding to the display screen, so that the actual luminous brightness of the light-emitting element can be calculated according to the first brightness and the second brightness, and the influence of ambient light is filtered out, so as to determine whether the light-emitting element has Aging, so that aging compensation is performed on the light-emitting element in time when aging occurs, and the accuracy of aging detection is improved.

进一步的,请参阅图2,图2是本发明实施例提供的另一种发光元件的亮度确定方法的流程示意图。具体的,如图2所示,本发明实施例的所述发光元件的亮度确定方法可以包括以下步骤:Further, please refer to FIG. 2 . FIG. 2 is a schematic flowchart of another method for determining the brightness of a light-emitting element provided by an embodiment of the present invention. Specifically, as shown in FIG. 2, the method for determining the brightness of the light-emitting element in the embodiment of the present invention may include the following steps:

201、对移动终端的显示屏进行分区,得到所述分区后的至少一个显示区域,且每一个显示区域配置有光传感器。201. Partition the display screen of the mobile terminal to obtain at least one display area after the partition, and each display area is configured with a light sensor.

具体实施例中,可预先在移动终端中配置多个光感器件如光传感器。比如,可预先通过对终端显示屏进行分区,划分得到多个显示区域,并为每一个显示区域配置其对应的光传感器。具体的,每一个光传感器可仅对应一个显示区域(用于测量该一个显示区域的亮度),或者可对应多个显示区域(可分别测量得到该多个显示区域的亮度),从而能够通过每一个显示区域对应的光传感器来进行亮度测量。In a specific embodiment, multiple photosensitive devices such as photosensors may be pre-configured in the mobile terminal. For example, the terminal display screen may be partitioned in advance to obtain multiple display areas, and a corresponding light sensor may be configured for each display area. Specifically, each light sensor may only correspond to one display area (for measuring the brightness of the one display area), or may correspond to multiple display areas (the brightness of the multiple display areas may be measured separately), so that each A light sensor corresponding to the display area is used for brightness measurement.

202、在当前显示区域包括的发光元件发光时,获取所述发光元件发光时所述当前显示区域的第一亮度。202. When the light emitting element included in the current display area emits light, acquire a first brightness of the current display area when the light emitting element emits light.

其中,该当前显示区域可以为终端显示屏划分得到的多个显示区域中的任一显示区域。Wherein, the current display area may be any display area among a plurality of display areas divided by the display screen of the terminal.

203、控制所述发光元件停止发光,并获取所述发光元件停止发光时所述当前显示区域的第二亮度。203. Control the light emitting element to stop emitting light, and acquire a second brightness of the current display area when the light emitting element stops emitting light.

204、计算所述第一亮度与所述第二亮度的差值,并将所述差值作为所述当前显示区域的发光元件的发光亮度。204. Calculate a difference between the first brightness and the second brightness, and use the difference as the light-emitting brightness of the light-emitting element in the current display area.

具体实施例中,由于通过显示屏任一显示区域中的发光元件进行发光时,检测到的显示区域的亮度往往包括发光元件的发光亮度,还包括受当前环境光影响反射的部分环境光的亮度。由此,在发光元件发光时检测到的亮度值直接作为该发光元件的发光亮度并不准确,可通过该当前显示区域对应的光传感器分别测量得到该当前显示区域的发光元件发光时的第一亮度以及该当前显示区域的发光元件不发光(停止发光)时的第二亮度来获取该当前显示区域的发光元件的实际发光亮度。具体可将该第一亮度减去第二亮度的差值作为该显示区域的发光元件的实际发光亮度,从而能够根据该发光元件的实际发光亮度判断其是否发生老化,以在确定发生老化时及时地对发生老化的发光元件进行补偿。也就是说,所述第一亮度和所述第二亮度分别为同一显示区域对应的光传感器测量得到的发光元件发光时该显示区域的亮度以及该发光元件不发光时该显示区域的亮度。In a specific embodiment, when light is emitted by a light-emitting element in any display area of the display screen, the detected brightness of the display area often includes the light-emitting brightness of the light-emitting element, and also includes the brightness of part of the ambient light reflected by the current ambient light. . Therefore, it is not accurate to directly use the luminance value detected when the light-emitting element emits light as the light-emitting luminance of the light-emitting element. The light sensor corresponding to the current display area can be respectively measured to obtain the first brightness value when the light-emitting element in the current display area emits light. The actual luminous brightness of the luminous elements in the current display area is obtained by using the luminance and the second luminance when the luminous elements in the current display area do not emit light (stop emitting light). Specifically, the difference between the first brightness minus the second brightness can be used as the actual luminous brightness of the light-emitting element in the display area, so that it can be judged according to the actual luminous brightness of the light-emitting element whether it is aging, so that when it is determined that aging occurs, it can be determined in time. Compensate for aging light-emitting elements. That is to say, the first brightness and the second brightness are the brightness of the display area when the light-emitting element emits light and the brightness of the display area when the light-emitting element does not emit light, measured by the light sensor corresponding to the same display area.

可选的,在进行发光元件的实际发光亮度确定时,为了确保满足视觉残留效果,不影响用户对终端的使用,可以将所述发光元件停止发光的时间与所述发光元件发光的时间的比值设置为不超过25%,即发光元件停止发光的时间在每个周期(发光时间+停止发光的时间)所占的占空比小于20%,以保证显示屏显示效果不变,避免对用户使用终端造成打扰。Optionally, when determining the actual luminous brightness of the light-emitting element, in order to ensure that the visual residual effect is satisfied and the user's use of the terminal is not affected, the ratio of the time when the light-emitting element stops emitting light to the time when the light-emitting element emits light can be calculated Set it to no more than 25%, that is, the duty cycle of the time when the light-emitting element stops emitting light is less than 20% in each cycle (lighting time + time to stop emitting light), so as to ensure that the display effect of the display screen remains unchanged and avoid using The terminal is causing interruptions.

205、判断所述当前显示区域的发光元件的发光亮度是否低于预设的亮度基准值。205. Determine whether the luminance of the luminous elements in the current display area is lower than a preset luminance reference value.

进一步的,在获取得到当前显示区域的发光元件的实际发光亮度之后,即可根据该实际发光亮度判断该显示区域的发光元件是否发生老化。具体的,可预先存储一个亮度基准值,从而可通过将该发光元件的实际发光亮度与该亮度基准值进行比较,并在该实际发光亮度低于该亮度基准值时确定该显示区域的发光元件发生老化,则可执行步骤206;否则,可表明该显示区域的发光元件未发生老化,则可不做任何处理。Further, after the actual luminous brightness of the light emitting elements in the current display area is acquired, it can be judged whether the light emitting elements in the display area are aging according to the actual luminous brightness. Specifically, a brightness reference value can be stored in advance, so that the actual luminous brightness of the light-emitting element can be compared with the brightness reference value, and when the actual luminous brightness is lower than the brightness reference value, the light-emitting element in the display area can be determined. If aging occurs, step 206 may be performed; otherwise, it may indicate that the light emitting elements in the display area are not aging, and no processing may be performed.

可选的,在进行老化检测时,该第一亮度对应的显示区域输出的图像即该当前显示区域发光元件发光时输出的图像可以为预置的纯色图像,该亮度基准值与该预置的纯色图像相对应,以进一步提升老化检测准确性。又或者,该亮度基准值可以是终端出厂时屏幕点亮后自动获取并存储的,或者由终端设计人员预先配置的,本发明实施例不做限定。Optionally, when performing aging detection, the image output from the display area corresponding to the first brightness, that is, the image output when the light-emitting element in the current display area emits light, may be a preset solid-color image, and the brightness reference value is the same as the preset Corresponding to solid color images to further improve the accuracy of aging detection. Alternatively, the brightness reference value may be automatically obtained and stored after the screen of the terminal is turned on when the terminal leaves the factory, or may be preconfigured by a terminal designer, which is not limited in this embodiment of the present invention.

206、确定所述发光元件发生老化,并按照预设的补偿规则对所述发光元件进行老化补偿。206. Determine that the light emitting element is aging, and perform aging compensation on the light emitting element according to a preset compensation rule.

进一步的,在确定显示屏中某一个或多个显示区域的发光元件发生老化之后,即可按照预设的补偿规则对该确定为发生老化的显示区域的发光元件进行老化补偿,比如通过调整该显示区域发光元件的驱动电流(具体可以是增加驱动电流)、增加该显示区域的发光元件的驱动电压、降低该显示区域的发光元件的发光亮度等方式进行补偿,本发明实施例不做限定。Further, after it is determined that the light-emitting elements in one or more display areas in the display screen are aging, aging compensation can be performed on the light-emitting elements in the display areas determined to be aging according to preset compensation rules, for example, by adjusting the The driving current of the light-emitting elements in the display area (specifically, increasing the driving current), increasing the driving voltage of the light-emitting elements in the display area, reducing the luminance of the light-emitting elements in the display area, etc. are compensated, which are not limited in the embodiment of the present invention.

应理解,该计算出的发光元件的发光亮度可以为该当前显示区域中包括的发光元件整体对应的发光亮度。由此,在进行老化补偿时,可同时对该显示区域的所有发光元件进行老化补偿。或者,进一步对该显示区域的发光元件依次进行老化检测之后,再针对性地进行老化补偿。It should be understood that the calculated light emitting brightness of the light emitting elements may be the light emitting brightness corresponding to the whole light emitting elements included in the current display area. Thus, when aging compensation is performed, aging compensation can be performed on all light emitting elements in the display area at the same time. Or, after aging detection is further performed on the light emitting elements in the display area in sequence, aging compensation is performed in a targeted manner.

在本发明实施例中,可通过对终端显示屏进行分区,划分得到多个显示区域,从而通过在显示区域包括的发光元件发光时获取发光元件发光时该显示区域对应的第一亮度,并通过控制发光元件停止发光,获取发光元件停止发光时该显示区域对应的第二亮度,使得能够通过将该第一亮度和第二亮度的差值作为该显示区域发光元件的发光亮度,而过滤掉环境光的影响,并根据计算出发光亮度确定该发光元件是否发生老化,从而在发生老化时及时地对该发光元件进行老化补偿,提升了老化检测的准确性。In the embodiment of the present invention, a plurality of display areas can be obtained by partitioning the display screen of the terminal, so as to obtain the first brightness corresponding to the display area when the light-emitting element included in the display area emits light when the light-emitting element emits light, and pass Control the light-emitting element to stop emitting light, and obtain the second brightness corresponding to the display area when the light-emitting element stops emitting light, so that the difference between the first brightness and the second brightness can be used as the light-emitting brightness of the light-emitting element in the display area to filter out the environment According to the influence of light, it is determined whether the light-emitting element is aging according to the calculated luminous brightness, so that aging compensation is performed on the light-emitting element in time when aging occurs, and the accuracy of aging detection is improved.

请参阅图3,图3是本发明实施例提供的一种亮度确定装置的结构示意图。具体的,本发明实施例的所述装置可设置于上述的移动终端中,该移动终端的显示屏由至少一个发光元件组成。如图3所示,本发明实施例的所述亮度确定装置可以包括亮度获取模块11、控制模块12以及计算模块13。其中,Please refer to FIG. 3 . FIG. 3 is a schematic structural diagram of an apparatus for determining brightness according to an embodiment of the present invention. Specifically, the device in the embodiment of the present invention can be set in the above-mentioned mobile terminal, and the display screen of the mobile terminal is composed of at least one light-emitting element. As shown in FIG. 3 , the apparatus for determining brightness in this embodiment of the present invention may include a brightness acquisition module 11 , a control module 12 and a calculation module 13 . in,

所述亮度获取模块11,用于在移动终端的显示屏包括的发光元件发光时,获取所述发光元件发光时所述显示屏的第一亮度。The brightness acquisition module 11 is configured to acquire a first brightness of the display screen when the light emitting element included in the display screen of the mobile terminal emits light when the light emitting element emits light.

具体实施例中,一般情况下,在点亮OLED,即通过显示屏(具体可以是终端显示屏中某一特定显示区域)中的发光元件进行发光时,通过亮度获取模块11检测到的显示区域的亮度即第一亮度往往包括发光元件的发光亮度,还包括受当前环境光影响反射的部分环境光的亮度。由此,将发光元件发光时亮度获取模块11检测到的亮度值直接作为该发光元件的发光亮度并不准确。具体的,该发光元件发光时显示区域对应的亮度值即第一亮度可是亮度获取模块11通过预置的光感器件如光传感器测量并获取得到的。In a specific embodiment, in general, when the OLED is turned on, that is, when the light-emitting element in the display screen (specifically, a specific display area in the terminal display screen) emits light, the display area detected by the brightness acquisition module 11 The brightness, ie, the first brightness, often includes the luminous brightness of the light-emitting element, and also includes the brightness of part of the ambient light reflected by the current ambient light. Therefore, it is not accurate to directly use the luminance value detected by the luminance acquisition module 11 when the luminous element emits light as the luminous luminance of the luminous element. Specifically, the luminance value corresponding to the display area when the light-emitting element emits light, that is, the first luminance, can be measured and acquired by the luminance acquisition module 11 through a preset photosensitive device such as a photosensor.

所述控制模块12,用于控制所述发光元件停止发光。The control module 12 is configured to control the light emitting element to stop emitting light.

所述亮度获取模块11,还用于获取所述发光元件停止发光时所述显示屏的第二亮度。The brightness obtaining module 11 is further configured to obtain the second brightness of the display screen when the light emitting element stops emitting light.

其中,该发光元件停止发光时显示屏对应的亮度值即第二亮度同样可以是亮度获取模块11通过预置的该光传感器测量并获取得到的。Wherein, the brightness value corresponding to the display screen when the light-emitting element stops emitting light, ie, the second brightness, can also be measured and obtained by the brightness acquisition module 11 through the preset light sensor.

进一步的,在亮度获取模块11获取得到发光元件发光时显示区域的第一亮度之后,控制模块12即可控制该显示区域的发光元件停止发光,并触发亮度获取模块11获取得到此时该显示区域对应的亮度值即第二亮度。由于该显示区域的发光元件并未发光,则该获取得到的第二亮度可作为当前环境光折射的亮度值。Further, after the brightness acquisition module 11 acquires the first brightness of the display area when the light-emitting element emits light, the control module 12 can control the light-emitting element in the display area to stop emitting light, and trigger the brightness acquisition module 11 to obtain the display area at this time. The corresponding brightness value is the second brightness. Since the light emitting element in the display area does not emit light, the obtained second brightness can be used as the brightness value of the current ambient light refraction.

所述计算模块13,用于根据所述亮度获取模块11获取的所述第一亮度和所述第二亮度,计算得到所述发光元件的发光亮度,以根据所述发光亮度对所述发光元件进行老化补偿。The calculation module 13 is configured to calculate the luminous brightness of the light-emitting element according to the first luminance and the second luminance acquired by the luminance acquisition module 11, so as to calculate the luminous brightness of the light-emitting element according to the luminous brightness. Perform aging compensation.

在亮度获取模块11获取得到显示区域中发光元件发光时的第一亮度及不发光时的第二亮度之后,计算模块13即可按照预设的算法过滤环境光的影响,计算出该显示区域中发光元件的实际发光亮度,比如将该第一亮度减去第二亮度的差值作为该显示区域的发光元件的实际发光亮度,从而能够根据该发光元件的实际发光亮度判断其是否发生老化,以在确定发生老化时及时地对发生老化的发光元件进行补偿。After the brightness acquisition module 11 acquires the first brightness when the light-emitting element in the display area emits light and the second brightness when it does not emit light, the calculation module 13 can filter the influence of ambient light according to a preset algorithm, and calculate the brightness of the light in the display area. The actual luminous brightness of the light-emitting element, for example, the difference between the first brightness minus the second luminance is used as the actual luminous brightness of the light-emitting element in the display area, so that it can be judged according to the actual luminous brightness of the light-emitting element whether it is aging, and When it is determined that aging occurs, the aging light-emitting element is compensated in time.

在本发明实施例中,可通过在移动终端的显示屏包括的发光元件发光时获取发光元件发光时该显示屏对应的第一亮度,并通过控制发光元件停止发光,获取发光元件停止发光时该显示屏对应的第二亮度,从而能够根据该第一亮度和第二亮度计算得到发光元件的实际发光亮度,而过滤掉环境光的影响,以根据计算出的实际发光亮度确定该发光元件是否发生老化,从而在发生老化时及时地对该发光元件进行老化补偿,提升了老化检测的准确性。In the embodiment of the present invention, the first brightness corresponding to the display screen when the light-emitting element is light-emitting can be obtained when the light-emitting element included in the display screen of the mobile terminal emits light, and by controlling the light-emitting element to stop emitting light, the first brightness when the light-emitting element stops emitting light can be obtained. The second brightness corresponding to the display screen, so that the actual luminous brightness of the light-emitting element can be calculated according to the first brightness and the second brightness, and the influence of ambient light is filtered out, so as to determine whether the light-emitting element has Aging, so that aging compensation is performed on the light-emitting element in time when aging occurs, and the accuracy of aging detection is improved.

进一步的,请参阅图4,图4是本发明实施例提供的另一种亮度确定装置的结构示意图。具体的,本发明实施例的所述装置可包括上述图3对应实施例中的亮度确定装置的亮度获取模块11、控制模块12以及计算模块13。进一步的,如图4所示,在本发明实施例中,所述装置对应的显示屏可被分为至少一个显示区域,且每一个显示区域配置有光传感器。Further, please refer to FIG. 4 , which is a schematic structural diagram of another device for determining brightness provided by an embodiment of the present invention. Specifically, the device in this embodiment of the present invention may include the brightness acquisition module 11 , the control module 12 and the calculation module 13 of the brightness determination device in the above embodiment corresponding to FIG. 3 . Further, as shown in FIG. 4 , in the embodiment of the present invention, the display screen corresponding to the device may be divided into at least one display area, and each display area is configured with a light sensor.

具体实施例中,移动终端中预先配置一个或多个光感器件如光传感器。具体的,终端显示屏可预先被划分得到多个显示区域,并为每一个显示区域配置其对应的光传感器。具体的,每一个光传感器可仅对应一个显示区域(用于测量该一个显示区域的亮度),或者可对应多个显示区域(可分别测量得到该多个显示区域的亮度),使得能够通过每一个显示区域对应的光传感器对该显示区域来进行亮度测量。In a specific embodiment, one or more photosensitive devices such as photosensors are preconfigured in the mobile terminal. Specifically, the display screen of the terminal can be divided into multiple display areas in advance, and a corresponding light sensor is configured for each display area. Specifically, each light sensor may only correspond to one display area (for measuring the brightness of the one display area), or may correspond to multiple display areas (the brightness of the multiple display areas may be measured separately), so that each A light sensor corresponding to a display area measures brightness of the display area.

其中,所述第一亮度和所述第二亮度分别为同一显示区域对应的光传感器测量得到的发光元件发光时该显示区域的亮度以及该发光元件不发光时该显示区域的亮度。Wherein, the first brightness and the second brightness are the brightness of the display area when the light-emitting element emits light and the brightness of the display area when the light-emitting element does not emit light, which are measured by the light sensor corresponding to the same display area.

进一步的,在本发明实施例中,所述第一亮度和所述第二亮度是通过预置的光传感器获取的;所述计算模块13可具体用于:Further, in the embodiment of the present invention, the first brightness and the second brightness are acquired through a preset light sensor; the calculation module 13 can be specifically used for:

计算所述第一亮度与所述第二亮度的差值,并将所述差值作为所述发光元件的发光亮度。calculating the difference between the first brightness and the second brightness, and using the difference as the light emitting brightness of the light emitting element.

具体实施例中,由于通过显示屏任一显示区域中的发光元件进行发光时,亮度获取模块11检测到的显示区域的亮度往往包括发光元件的发光亮度,还包括受当前环境光影响反射的部分环境光的亮度。由此,在发光元件发光时检测到的亮度值直接作为该发光元件的发光亮度并不准确,亮度获取模块11可通过该显示区域对应的光传感器分别测量得到该显示区域的发光元件发光时的第一亮度以及该显示区域的发光元件不发光(停止发光)时的第二亮度,并通过计算模块13来获取该显示区域的发光元件的实际发光亮度。计算模块13具体可将该第一亮度减去第二亮度的差值作为该显示区域的发光元件的实际发光亮度,从而能够根据该发光元件的实际发光亮度判断其是否发生老化,以在确定发生老化时及时地对发生老化的发光元件进行补偿。In a specific embodiment, when the light-emitting element in any display area of the display screen emits light, the brightness of the display area detected by the brightness acquisition module 11 often includes the light-emitting brightness of the light-emitting element, and also includes the reflected part affected by the current ambient light The brightness of the ambient light. Therefore, it is not accurate to directly use the luminance value detected when the light-emitting element emits light as the light-emitting luminance of the light-emitting element. The brightness acquisition module 11 can obtain the luminance of the light-emitting element in the display area by measuring respectively through the light sensor corresponding to the display area. The first luminance and the second luminance when the light-emitting elements in the display area do not emit light (stop emitting light) are obtained through the calculation module 13 to obtain the actual light-emitting luminance of the light-emitting elements in the display area. Specifically, the calculation module 13 may use the difference between the first luminance minus the second luminance as the actual luminous luminance of the light-emitting element in the display area, so that it can be judged according to the actual luminous luminance of the light-emitting element whether it is aging, so as to determine the occurrence of aging. When aging, the aging light-emitting element is compensated in time.

可选的,在进行发光元件的实际发光亮度确定时,为了确保满足视觉残留效果,所述发光元件停止发光的时间与所述发光元件发光的时间的比值可被设置为不超过25%,从而确保显示屏显示效果不变,以避免对用户使用终端造成打扰。Optionally, when determining the actual light-emitting brightness of the light-emitting element, in order to ensure that the visual persistence effect is satisfied, the ratio of the time when the light-emitting element stops emitting light to the time when the light-emitting element emits light can be set to no more than 25%, so that Ensure that the display effect of the display screen remains unchanged to avoid disturbing the user's use of the terminal.

进一步可选的,在本发明实施例中,所述装置还可包括:Further optionally, in the embodiment of the present invention, the device may further include:

判断模块14,用于判断计算得到的所述发光元件的发光亮度是否低于预设的亮度基准值;A judging module 14, configured to judge whether the calculated luminous brightness of the light-emitting element is lower than a preset luminance reference value;

补偿模块15,用于在所述判断模块14的判断结果为所述发光元件的发光亮度低于所述亮度基准值时,确定所述发光元件发生老化,并按照预设的补偿规则对所述发光元件进行老化补偿。The compensation module 15 is configured to determine that the light-emitting element is aging when the judging result of the judging module 14 is that the light-emitting luminance of the light-emitting element is lower than the brightness reference value, and correct the luminous element according to a preset compensation rule. The light-emitting element is compensated for aging.

进一步的,在计算模块13获取得到各显示区域的发光元件的实际发光亮度之后,判断模块14即可根据该实际发光亮度判断该显示区域的发光元件是否发生老化。具体的,终端中可预先存储一个亮度基准值,从而判断模块14可通过将该发光元件的实际发光亮度与该亮度基准值进行比较,并在该实际发光亮度低于该亮度基准值时确定该显示区域的发光元件发生老化;否则,可表明该显示区域的发光元件未发生老化,则可不做任何处理。其中,该亮度基准值可以是屏幕点亮时自动获取并存储的,或者由终端设计人员预先配置的,本发明实施例不做限定。Further, after the calculation module 13 obtains the actual luminous brightness of the light-emitting elements in each display area, the judging module 14 can judge whether the light-emitting elements in the display area are aging according to the actual luminous brightness. Specifically, a brightness reference value may be pre-stored in the terminal, so that the judging module 14 may compare the actual luminous brightness of the light-emitting element with the brightness reference value, and determine the brightness when the actual luminous brightness is lower than the brightness reference value. The light-emitting elements in the display area are aging; otherwise, it can be shown that the light-emitting elements in the display area are not aging, and no treatment is required.
