图1示出了本公开根据一示例性实施例示出的一种显示屏控制方法流程图。
在步骤S101中,获取所述色温传感器采集的第一色温参数。
所述色温传感器是色彩传感器的一种,可以通过光电二极管、电压转换器等元件构成,能够通过采集环境中的可见光和不可见光,拟合得到当前环境光线的色温参数。所述第一色温参数表示由所述色温传感器采集到的当前 环境光的色温参数。
在步骤S102中,根据所述显示屏当前的亮度参数和第一对应关系,确定色温补偿值,并根据所述色温补偿值调整所述第一色温参数,得到第二色温参数,其中,所述第一对应关系用于表征所述显示屏亮度参数与色温补偿值之间的对应关系。
由于显示屏的漏光现象是由于显示屏背光源与晶体间由于结构问题或公差导致的缝隙溢出造成的,显示屏亮度越高,所述漏光现象越严重,因此可以通过显示屏当前的亮度参数(如尼特值)表示所述显示屏当前的漏光程度。根据所述显示屏当前的亮度参数和所述显示屏亮度参数与色温补偿值之间的对应关系,可以确定在显示屏以当前亮度参数工作的情况下,由漏光光线产生的色温参数,即所述色温补偿值。通过去除所述第一色温参数中,由于漏光光线产生的色温参数得到第二色温参数。所述第二色温参数即为通过色温补偿值对所述第一色温参数进行调整后,真实环境光线产生的色温参数。
在步骤S103中,根据所述第二色温参数,控制所述显示屏显示画面的色温。
根据经过调整后得到的由真实环境光线产生的色温参数,控制所述显示屏显示画面的色温。例如,在环境光线温呈暖色的情况下,显示屏会将显示画面调整至偏暖色调,在环境光线呈冷色的情况下,显示屏会将显示画面调整至偏冷色调,使显示屏在不同光线环境下呈现给用户的色彩观感保持一致,达到真彩显示的效果。
本公开所述方法,通过获取到的色温补偿值,对色温传感器采集到的第一色温参数进行补偿调整,并通过补偿调整后得到的第二色温参数控制显示屏显示画面的色温,使得终端设备能够屏蔽由于显示屏漏光对环境色温带来的影响,使显示屏能够根据真实的环境色温调节显示画面的色温,提升真彩显示功能的可靠性与用户体验。
在一个可选的实施例中,所述第一色温参数包括多个通道的子参数;
所述根据终端设备显示屏的当前亮度参数和第一对应关系,确定色温补 偿值,并根据所述色温补偿值调整所述第一色温参数,得到第二色温参数,包括:
根据所述显示屏当前的亮度参数和第一对应关系,确定所述第一色温参数中每个通道的子参数对应的色温补偿值;
可选的,所述色温参数可以分别由所述色温传感器的C、R、G、B、W五个通道获取,其中,通过RGB通道获取三色光源的色温参数,通过W通道获取白光的色温参数,通过C通道获取三色光源与不可见光源的总色温参数。上述五个通道中,每个通道的子参数均受显示屏漏光影响,通过分别获取上述五个通道中每个子参数对应的色温补偿值,可以确定在显示屏以当前亮度参数工作的情况下,由于漏光现象对每种色温参数造成的影响程度。
根据所述每个通道的子参数对应的色温补偿值调整所述第一色温参数中每个通道的子参数,得到所述第二色温参数。
可选的,对所述第一色温参数中每个通道的子参数进行调整,得到经调整后的每个通道的子参数,即所述第二色温参数。
本公开所述方法,通过获取到的色温补偿值,对色温传感器采集到的第一色温参数中每个通道的子参数进行补偿调整,以实现对色温传感器采集到的色温结果进行精确补偿调整。
图2是本公开根据一示例性实施例示出的一种对应关系标定流程图;
在步骤S201中,在预设标定环境下,获取所述显示屏以预设亮度参数显示画面时所述色温传感器采集的色温参数,以及所述色温传感器采集的色温参数为预设色温参数时所述显示屏的亮度参数。
可以在设备生产阶段通过最每台终端设备进行标定过程以获取每台终端设备的第一对应关系,即所述显示屏亮度参数与色温补偿值之间的对应关系。在一个示例中,所述预设标定环境可以通过黑箱实现,所述黑箱由低反射率的黑色不透光材质构成,用于屏蔽环境光线以及显示屏画面亮度对所述色温传感器的影响,使所述色温传感器仅能够通过显示屏的漏光光线获取所述色温参数。
在所述预设标定环境下,通过获取所述显示屏以预设亮度参数显示画面使所述色温传感器采集的色温参数,用于表示在显示屏的漏光现象严重情况下漏光光线的色温参数,所述预设亮度参数可以是所述显示屏能够达到的最高亮度参数。之后,获取所述色温传感器采集的色温参数为预设色温参数时所述显示屏的亮度参数。所述亮度参数用于表示所述显示屏在漏光无法对色温传感器产生影响情况下的亮度参数。在一个示例中,可以将0作为所述预设色温参数,此时,漏光光线的色温已无法被色温传感器采集到,漏光光线对色温传感器的影响最小。
在步骤S202中,根据所述显示屏的预设亮度参数、所述显示屏以预设亮度参数显示画面时所述色温传感器采集的色温参数,和所述色温传感器采集的色温参数为预设色温参数时所述显示屏的亮度参数,确定所述第一对应关系。
可选的,通过在显示屏的漏光现象最严重情况下漏光光线的色温参数和所述显示屏在漏光现象不对色温传感器构成影响情况下的亮度参数,可以确定所述显示屏亮度参数与色温补偿值之间的对应关系。在一个示例中,可以构建以所述显示屏亮度参数为自变量,所述色温传感器采集的色温参数为因变量的模型,根据在所述显示屏以预设亮度参数下所述色温传感器采集的色温参数和所述色温参数为预设色温参数时所述显示屏的亮度参数,确定所述显示屏亮度参数与所述色温参数之间的线性对应关系,即所述第一对应关系。根据所述第一对应关系,可以确定所述显示屏在以任一亮度参数工作时所述色温传感器采集到的显示屏漏光光线的色温参数,即所述色温补偿值。
在一个示例中,所述色温传感器采集的色温参数包括多个通道的子参数。
同样的,可以获取所述显示屏以预设亮度参数显示画面时,所述色温传感器采集的色温参数中每个通道的子参数,以及所述色温传感器采集的色温参数中每个通道的子参数分别为预设色温参数时所述显示屏的亮度参数,并分别构建以所述显示屏亮度参数为自变量,所述色温参数中每个通道子参数为因变量的模型。
在所述色温传感器通过C、R、G、B、W五个通道分别获取所述子参数的情况下,可以基于上述方法,确定所述显示屏亮度关系与所述每个子参数之间的线性对应关系,即所述每个通道的子参数的第一对应关系。根据所述第一的对应关系,可以确定所述显示屏以任一亮度参数工作时所述色温传感器采集到的显示屏漏光光线的色温参数中每一个通道的子参数,即所述色温补偿值。
本公开所述方法,通过在预设标定环境下,确定所述显示屏亮度参数引起的漏光现象带来的色温变化,确定所述第一对应关系,使每一台终端设备都能够根据实际的漏光程度确定特有的第一对应关系,以在后续过程能够个性化调整所述第一色温参数。此外,通过确定每个通道的子参数的第一对应关系,提升了获取到的所述补偿调整参数的精确性,从而提升所述第二色温参数的可靠性。
在一个可选的实施例中,所述在预设标定环境下,获取所述显示屏以预设亮度参数显示画面时所述色温传感器采集的色温参数,包括:
在预设标定环境下,控制所述显示屏以预设亮度参数显示白色图像,并获取所述色温传感器采集的色温参数。
对于LCD(液晶屏)等通过背光源与液晶材料组成的显示屏,在以预设亮度显示纯白图卡即白色图像的状态下,所述液晶材料无需改变内部分子的排列状况,在所述背光源与晶体间存在缝隙的情况下,所述漏光现象达到最严重程度,因此可以将所述显示屏以预设亮度参数显示白色图像的状态作为所述显示屏以预设亮度参数显示画面的状态同样的,同样的,所述预设亮度参数可以是显示屏能够达到的最高亮度参数。
本公开所述方法,通过控制所述显示屏以预设亮度参数显示白色图像,使所述终端设备处于漏光最严重状态,此时获取所述色温传感器采集的色温参数,能够准确确定显示屏的漏光现象最严重情况下漏光光线的色温参数。
在一个可选的实施例中,所述获取所述色温传感器采集的色温参数为预设色温参数时所述显示屏的亮度参数,包括:
控制显示屏以预设亮度参数为起始参数,逐渐降低所述亮度参数,在所述色温传感器采集的色温参数为预设色温参数时,获取所述显示屏的亮度参数。
可选的,在获取显示屏的漏光现象最严重情况下漏光光线的色温参数后,可以通过降低所述显示屏亮度以使所述亮度参数逐渐下探,在所述色温参数为预设色温参数时,确定所述亮度参数,即所述显示屏在漏光现象不对色温传感器构成影响的情况下的亮度参数。若所述色温传感器采集的色温参数中包括多个通道的子参数,可以在所述亮度参数的下探过程中依次获取每个子参数达到预设色温参数时显示屏的亮度参数。
本公开所述方法,通过逐渐降低所述亮度参数至所述色温传感器采集的色温参数为预设色温参数,获取所述显示屏的亮度参数,以准确获取到所述显示屏在漏光现象不对色温传感器构成影响的情况下的亮度参数。
在一个可选的实施例中,在确定所述第一对应关系之后,所述方法还包括:
将所述第一对应关系保存至终端设备的持久化分区。
可选的,所述持久化分区(persist分区)能够保证数据在终端设备中的持久化存储。由于每一台终端设备在同一亮度参数下的漏光程度不同,因此若所述第一对应关系丢失,则只能通过再次标定获取,为用户带来不便。因此可以在产线获取所述第一对应关系后,将所述第一对应关系同所述终端设备的蓝牙、相机校准数据等基本数据共同存储至所述持久化分区,以防止用户格式化或重装系统造成所述第一对应关系的丢失。
在根据所述显示屏当前的亮度参数和第一对应关系,确定色温补偿值之前,所述方法还包括:
从所述终端设备的持久化分区中获取所述第一对应关系。
可选的,在终端设备需要获取所述第一对应关系以确定所述色温补偿值前,可以获取在产线标定过程中预存在持久化分区中的所述第一对应关系,以便于后续对所述第一色温参数的调整。
本公开所述方法,通过在产线的标定阶段将所述第一对应关系存储至终端设备的持久化分区,防止用户格式化或重装系统造成所述第一对应关系的丢失。
在一个可选的实施例中,所述根据终端设备显示屏的当前亮度参数和第一对应关系,确定色温补偿值,并根据所述色温补偿值调整所述第一色温参数,得到第二色温参数,包括:
响应于当前环境亮度参数小于环境亮度阈值,根据终端设备显示屏的当前亮度参数和第一对应关系,确定色温补偿值,并根据所述色温补偿值调整所述第一色温参数,得到第二色温参数。
可选的,由于所述第一色温参数包含环境光线的真实色温参数以及所述显示屏漏光光线的色温参数,而在环境观光线越强的情况下,所述环境光线的真实色温参数在所述第一色温参数中的占比越高,漏光现象对所述显示屏真彩显示的影响越小。因此可以设置环境亮度阈值,在环境光线亮度参数大于所述环境亮度阈值的情况下,停止对所述第一色温参数的补偿调整以减少终端设备的运算压力。
而在环境光线偏弱的情况下,所述显示屏漏光光线的色温参数在所述第一色温参数中的占比提高,漏光现象对所述显示屏真彩显示的影响随之增大,可以在所述环境光线亮度参数小于所述亮度阈值的情况下,启动对所述第一色温参数的补偿调整过程,使显示屏能够根据真实的环境色温调节显示画面的色温,提升了真彩显示功能的可靠性与用户体验。
本公开所述方法,通过设置环境亮度阈值,在环境光线亮度参数大于所述环境亮度阈值的情况下,停止对所述第一色温参数的补偿调整以减少终端设备的运算压力,在所述环境光线亮度参数小于所述环境亮度阈值的情况下,启动对所述第一色温参数的补偿调整过程,使显示屏能够根据真实的环境色温调节显示画面的色温,提升了真彩显示功能的可靠性与用户体验。
在一个可选的实施例中,所述色温传感器位于所述终端设备屏幕边缘的 窄缝中。
当前,所述色温传感器通常设置于显示屏的晶体下方,而对于存在漏光现象的显示屏,该设置方式会导致所述色温传感器更易采集到漏光光线的色温参数,而通过将所述色温传感器设置于所述终端设备屏幕边缘的窄缝中,可以使所述色温传感器不易误采集到漏光光线的色温参数,以减少漏光现象对色温传感器的影响。
本公开所述方法,通过将所述色温传感器设置于所述终端设备屏幕边缘的窄缝中,进一步避免漏光现象对色温传感器的影响。
