在步骤S1中,检测显示面板是否处于低亮度模式和/或低环境光模式,其中,在所 述低亮度模式下,所述显示面板发光的第一亮度小于第一预设亮度,在所述低环境光模式下,所述显示面板所处环境中环境光的第二亮度小于第二预设亮度。
在一个实施例中,可以通过光电传感器接收环境光,并生成响应的感应电流,根据感应电流的大小来确定环境光的第二亮度。
在一个实施例中,显示面板可以是液晶显示面板,在这种情况下,可以通过检测背光模组发光的亮度来确定显示面板发光的第一亮度。
在一个实施例中,显示面板可以是有机发光二极管显示面板(也即OLED),在这种情况下,可以通过检测像素单元中子像素的驱动电流来确定显示面板发光的第一亮度。
需要说明的是,检测第一亮度和第二亮度的方式并不限于上述方式,可以根据需要以及显示面板所在的设备来选择检测方式。
在一个实施例中,显示面板可以根据环境光的亮度调节自身发光的亮度,例如在环境光的第二亮度小于第二预设亮度的情况下,可以将自身发光的亮度调节至小于第一预设亮度,也即调整为低亮度模式,但是,该调节过程需要一段时间才能完成。因此,除了在显示面板发光的亮度小于第一预设亮度的情况下,还可以在环境光的亮度低于第二预设亮度的情况下,或者显示面板发光的亮度小于第一预设亮度且环境光的亮度低于第二预设亮度的情况下,确定显示面板处于低亮度模式,以便及时地开启护眼模式。
在一个实施例中,第一预设亮度和第二亮度可以根据需要进行设置。
例如,第一预设亮度可以大于或等于1nit,且小于或等于1.8nit,优选地可以设置为1.5nit;再例如,第二预设亮度可以大于或等于0.08lux,且小于或等于0.12lux,优选地可以设置为0.1lux。
在步骤S2中,在确定所述显示面板处于低亮度模式和/或低环境光模式时,开启护眼模式,所述护眼模式为相对所述低亮度模式进一步降所述显示面板中低损伤用户眼睛的颜色分量的亮度的模式。
在一个实施例中,在显示面板的像素单元包括红色子像素、绿色子像素、蓝色子像素的情况下,可以通过降低蓝色子像素的亮度来降低该颜色分量。而在显示面板的像素单元包括其他颜色子像素的情况下,降低该颜色分量方式则可以相应调整,例如在显示面板的像素单元包括青色子像素、品红子像素、黄色子像素的情况下,可以通过降低青色子像素和品红子像素的亮度来降低该颜色分量。以下主要在像素单元包括红色子像素、绿色子像素、蓝色子像素的情况下的对本公开的实施例进行示例性说明书。
在一个实施例中,通过在显示模板处于低亮度模式和/或低环境光模式的情况下,也即显示面板发光亮度较低,和/或环境光较低的情况下,自动开启护眼模式,以进一步降低显示面板中损伤用户眼睛的颜色分量,无需用户手动操作,从而避免了大部分对于显示面板的功能不熟悉的用户因未查找或找不到进行上述调节的功能,导致无法有效地保护眼睛,因此极大地提高了保护用户的范围。
图2是根据一示例性实施例示出的另一种显示控制方法的示意流程图。如图2所示,在图1所示实施例的基础上,开启护眼模式,包括:
在步骤S21中,降低所述显示面板的像素单元中蓝色子像素的亮度,并根据黑体轨迹线和所述蓝色子像素被降低的亮度,调整所述像素单元中其他子像素的亮度。
在一个实施例中,像素单元可以包括红色子像素、绿色子像素和蓝色子像素,还可以进一步包括白色子像素,并且每种颜色子像素的数量可以根据需要进行设置,对此,本公开不做限制。
在一个实施例中,第一亮度降低的情况可以是用户通过手动调节显示面板的发光亮度来降低;也可以是显示面板在感应到环境光亮度降低后,自动降低亮度。
在一个实施例中,第一亮度小于第一预设亮度,也即显示面板发光的亮度较低的情况,第二亮度小于第二预设亮度,也即环境光的亮度较低的情况,在这两种情况之一,或两种情况并存时,人眼对于颜色的敏感度也会降低,过亮的光线会对人眼造成较大的损伤。并且,其中较强的蓝光会对视网膜生极大的伤害,轻则诱发干眼症、眼疲劳、生物钟紊乱,严重的会导致眼睛黄斑变性,视力受损,并且蓝光也干扰人体分泌褪黑素,导致难以入眠。
因此在上述两种情况下,或两种情况并存的情况下,可以降低显示面板的像素单元中蓝色子像素的亮度,但是,只降低蓝色子像素的亮度会导致显示的画面的颜色朝着蓝色的补色,也即黄色,发生色偏,进而导致画面变黄。因此可以进一步根据黑体轨迹线和蓝色子像素被降低的亮度,调整像素单元中其他子像素的亮度。
图3是根据一示例性实施例示出的黑体轨迹线的示意图。
如图3所示,在CIE色度图中,其中的左下为蓝色,右下为红色,上方为绿色,黑体轨迹线表示CIE色度图中不同温度黑体(普朗克辐射体)的色度曲线,将显示的颜色调整为黑体轨迹线上的点,即可使得人眼观看到白色。
在一个实施例中,当降低像素单元中蓝色子像素的亮度时,可以根据黑体轨迹线调整像素单元中其他子像素的亮度(可以包括提高某些子像素的亮度,也可以包括降低某些子像素的亮度),使得调整后的像素单元发出的光的色度仍沿着黑体轨迹线变化的趋势变化,例如对于发白光的像素单元而言,调整后的像素单元发出白光的色度 仍位于黑体轨迹线上,从而保证像素单元显示的颜色不会发生明显的色偏,在降低蓝光实现对用户眼睛保护的同时,还保证了用户的观看效果几乎不会受到影响。
需要说明的是,上述显示面板可以具有供用户手动操作开启和关闭上述调节的功能的开关,基于此,用户可以设置进行上述自动调节,也可以设置为不进行上述自动调节。
可选地,还可以进一步考虑时间因素,也即在所述第一亮度小于第一预设亮度,和/或所述第二亮度小于第二预设亮度,和/或处于预设时间段的情况下,降低所述显示面板的像素单元中蓝色子像素的亮度,并根据黑体轨迹线和所述蓝色子像素被降低的亮度,调整所述像素单元中其他子像素的亮度。
在一个实施例中,预设时间段可以由用户预先设置,其中,预设时间段可以是一个夜间时段,例如22:00至24:00,当处于该预设时间段时,可以确定用户即将关灯睡眠,也即会在床上使用手机,因此可以在该时段进行上述调节,以保证用户在床上关灯使用手机的情况下,眼睛能够受到有效的保护,并且几乎不会影响用户观看的视觉效果。
图4是根据一示例性实施例示出的又一种显示控制方法的示意流程图。如图4所示,在图1所示实施例的基础上,开启护眼模式,包括:
在步骤S22中,降低所述显示面板的像素单元中蓝色子像素的亮度,并根据黑体轨迹线和所述蓝色子像素被降低的亮度,调整所述像素单元中其他子像素的亮度,使所述像素单元的亮度降低10%至20%。
在一个实施例中,虽然根据图1所示的实施例,通过降低像素单元中蓝色子像素的亮度,以及调整其他子像素的亮度,可以在有效保护用户眼睛的同事,降低对用户观看效果的影响。但是如果调整的结果使得像素单元的亮度降低过多,仍会使得用户觉察到显示面板显示的画面明显变暗。
因此可以根据像素单元的亮度降低10%至20%的程度来降低蓝色子像素的亮度,并调整其他子像素的亮度,以使得对于像素单元亮度的调整,仅会在较小的程度上降低像素单元的亮度,从而进一步降低调整像素单元中子像素的亮度之后对用户观看效果的影响,甚至在某些环境下,可以保证用户觉察不到像素单元亮度的改变。
其中,在显示面板为液晶显示面板的情况下,可以通过调整像素单元中蓝色子像素和其他子像素的公共电极的电压,来改变对应液晶的偏转程度,进而控制对于蓝色子像素发光的亮度以及其他子像素发光的亮度的改变程度。
在显示面板为有机发光二极管显示面板的情况下,可以通过调整像素单元中蓝色子像素和其他子像素的驱动电流,来控制对于蓝色子像素发光的亮度以及其他子像素 发光的亮度的改变程度。
图5是根据一示例性实施例示出的又一种显示控制方法的示意流程图。如图5所示,在图2所示实施例的基础上,所述调整所述像素单元中其他子像素的亮度包括:
在步骤S211中,降低所述像素单元中绿色子像素的亮度,和/或提高所述像素单元中红色子像素的亮度。
在一个实施例中,以发出白光的像素单元为例,该像素单元发出白光的色度在调整前就在图3所示的黑体轨迹线上,而在降低蓝色子像素发光的亮度时,为了使得调整后的像素单元发出的光的色度仍然在黑体轨迹线上,可以降低绿色子像素发光的亮度和/或提高红色子像素的亮度,从而使得调整后的像素单元发光的色度仍然位于黑体轨迹线上,只不过向右移动了,进而保证用户观看到的像素单元发光的色度几乎没有变化,从而降低对用户观看的影响。
其中,以液晶显示面板为例,可以通过降低蓝色子像素和绿色子像素中像素电极的电压来降低两者的透过率,实现降低两者亮度的效果,例如可以将蓝色子像素中像素电极的电压降低20%,将绿色子像素中像素电极的电压降低10%,和/或将红色子像素的亮度提高5%。
在一个实施例中,对于发出彩色光(例如黄光、绿光等)的像素单元,与发出白光的像素单元类似,也可以通过相同的方式和幅度调整蓝色子像素、绿色子像素和/或红色子像素的发光亮度。
以发绿光的像素单元为例,发出绿光的色度在调整前并非位于图3所示的黑体轨迹线上,而是位于黑体轨迹线上方的区域,在降低蓝色子像素发光的亮度时,为了使得调整后的像素单元发出的光的色度仍按照黑体轨迹线变化的趋势变化,也即在CIE色度图中向右移动,可以降低绿色子像素发光的亮度,或提高红色子像素发光的亮度,还可以既降低绿色子像素发光的亮度,又提高红色子像素发光的亮度,从而使得调整后的像素单元发光的色度与调整前相近,进而保证用户观看到的像素单元发光的色度几乎没有变化,从而降低对用户观看的影响。
图6是根据一示例性实施例示出的又一种显示控制方法的示意流程图。如图6所示,在图1所示实施例的基础上,检测显示面板是否处于低亮度模式和/或低环境光模式,包括:
在步骤S11中,在所述第一亮度小于第一预设亮度,和/或所述第二亮度小于第二预设亮度的情况下,记录所述第一亮度小于所述第一预设亮度的第一时长,和/或记录所述第二亮度小于所述第二预设亮度的第二时长;其中,在所述第一预设时长大于第一预设时长的情况下,确定所述显示面板处于低亮度模式,和/或在所述第二时长大于 第二预设时长的情况下,确定所述显示面板处于低环境光模式。
在一个实施例中,由于本公开实施例可以在第一亮度小于第一预设亮度,和/或第二亮度小于第二预设亮度的情况下,自动执行上述调节像素单元亮度的过程。但是在某些情况下,虽然第一亮度小于第一预设亮度,和/或第二亮度小于第二预设亮度,但是用户并不需要调节像素单元亮度,例如用户携带配置有上述显示面板的终端从寝室关灯准备外出,那么在关灯时也会出存在第二亮度小于第二预设亮度的情况,但是用户即将马上进入户外明亮的环境中,所以并不需要调节显示面板的亮度。
基于此,可以通过判断第一亮度小于所述第一预设亮度的第一时长是否足够长(大于第一预设时长),和/或记录第二亮度小于所述第二预设亮度的第二时长是否足够长(大于第二预设时长),以确定用户是否稳定地处于环境光亮度较低,或者手机亮度较低的情况下,并仅仅用户稳定地处于环境光亮度较低,或者手机亮度较低的情况下,才执行上述进入护眼模式的操作,降低显示面板的像素单元中蓝色子像素的亮度。而在用户并未稳定地处于环境光亮度较低,或者手机亮度较低的情况下,则可以继续保持显示面板以原亮度发光,从而避免误判断用户所处的情况,而调节显示屏幕的亮度进入护眼模式。
图7是根据一示例性实施例示出的又一种显示控制方法的示意流程图。如图7所示,在图1所示实施例的基础上,上述方法还包括:
在步骤S3中,确定所述显示面板退出低亮度模式和/或低环境光模式时,关闭护眼模式。
在一个实施例中,当显示面板退出低亮度模式时,显示面板的亮度可以恢复至接近正常水平,在这种情况下,用户一般需要观看亮度较高的画面,因此可以进一步退出护眼模式,保证用户的观看效果。
图8是根据一示例性实施例示出的又一种显示控制方法的示意流程图。如图8所示,在图7所示实施例的基础上,确定所述显示面板退出低亮度模式包括:
在步骤S31中,在所述第一亮度提高至大于所述第一预设亮度,确定显示面板退出低亮度模式;在所述第二亮度提高至大于所述第二预设亮度的情况下,确定所述显示面板退出低环境光模式。
