具体实施方式
为了能够更加详尽地了解本申请实施例的特点与技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
申请号为201810965920.5的专利公开了：针对OLED显示屏的全面屏结构，将红外线发射器设置在受话器的出声孔内，配置于发射红外光；红外线接收器设置在显示屏的显示区的下方，配置于接收反射回的红外光，根据发射红外光和反射回的红外光来实现接近功能。
现有技术中，有两种确定环境光的亮度信息的方式：
第一种是利用导光柱将外界环境光传递至感光器件表面，此种方式需要保证显示屏的屏幕光不能干扰感光器件，故需要采用较大的黑边以避免屏幕光信号对感光器件的干扰。在终端具体为手机的情况下，如图1所示，图1为手机的显示屏所在平面的部分截图，图1中左边的圆形区域为手机的摄像头，图1中右边的小的圆形区域为感光器件的位置区域，该小的圆形区域外侧的环形区域为黑边区域，感光器件上方的区域为手机的听筒，由于在感光器件的周围设置了较大的黑边区域，缩小了显示屏的显示面积，降低了显示屏的屏占比。
第二种是直接将光感器件放置在显示屏的下方，如图2所示，终端通过光感器件采集到的屏幕光和环境光的总亮度信息，终端获取当前显示屏的截图信息，并在该截图信息中获取当前显示屏上的屏幕颜色信息和屏幕亮度等级，终端利用线性拟合的方式对该屏幕颜色信息和屏幕亮度等级进行拟合，来确定出显示屏上的显示亮度信息，然后终端利用印制电路板(Printed Circuit Board，PCB)板上的感光器件获取到的包括屏幕光和环境光的总亮度信息与该显示亮度信息，来确定当前的环境光中的亮度信息，并根据该环境光中的亮度信息来调节显示屏的亮度，由于终端获取到的显 示屏上的屏幕颜色信息为彩色信息，并非是单一色信息，使得终端进行线性拟合时得到的局部数据为非线性数据，终端根据该非线性数据计算得到的显示亮度信息的准确度低，从而导致终端确定的环境光中的亮度信息的准确度低。
其中，通过脉冲宽度调制(Pulse width modulation，PWM)方式也可以进行显示屏屏幕亮度调节，PWM调节是通过改变显示屏屏幕亮、灭交替的时间来调节显示屏屏幕亮度。在终端中设置有PWM亮度调节方式的情况下，终端可以在显示屏屏幕不亮的情况下，终端将显示屏的下方的感光器件获取的光信号直接作为环境光的亮度信息，并根据该环境光的亮度信息来调节终端显示屏屏幕的亮度，但是此种显示屏屏幕亮度调节方式只能应用于设置有PWM调节方式的终端中，具有限制性。
对于现有技术中存在的问题，具体可通过实施例一和实施例二中的方法进行解决

示例性的，如图5所示，终端通过第一光感传感器内部光敏二极管CH0采集屏幕光，得到第一光感值，终端通过第二光感传感器内部光敏二极管CH1采集环境光和屏幕光，得到第二光感值，终端根据第一光感值和第二光感值，确定环境光的亮度信息，并对该亮度信息进行电信号放大和A/D转换器转换。电源为终端显示屏供电，地址选择可设置其传感器内部寄存器(指令寄存器和模数转换(Analog-to-Digital Converter，ADC)寄存器)，通过其相应指令控制器件的接收积分时间、模拟增益、数字增益等参数。终端可通过集成电路总线(Inter-Integrated Circuit，IIC)接口与光感传感器通信，并且通过中断对终端显示屏的亮度进行调节，通过控制线通知终端的显示屏亮度，通过数据线进行数据传输。
示例性的，如图6所示，终端显示屏四周的黑边区域的局部位置印刷无色扩散油，将第二光感传感器(IC2)设置于印刷无色扩散油的黑边区域下方的主板上，将第一光感传感器(IC1)设置于印刷黑色油墨的黑边区域下方的主板上，第一光感传感器和第二光感传感器之间相邻设置，利用第一光感传感器采集屏幕光，利用第二光感传感器采集环境光和屏幕光，得到第二光感值，根据第一光感值和第二光感值，确定环境光的亮度信息，根据亮度信息调节显示屏屏幕的亮度。
可以理解的是，终端在利用第一光感传感器得到第一光感值的情况下，终端可直接根据包括环境光和屏幕光的第二光感值以及第一光感值确定出环境光中的亮度信息，不需要终端获取当前显示屏的截图信息，根据该截图信息中的彩色信息进行线性拟合来得到包括非线性数据的线性数据，并根据包括非线性数据的线性数据来确定出环境光中的亮度信息，提高了终端确定的环境光中的亮度信息的准确度。
