需要说明的是,本申请的说明书中的术语“第一”、“第二”等(如果存在)是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反,它们仅是与本申请的一些方面相一致的装置和方法的例子。
在显示技术领域中,显示屏幕的状态发生变化会导致显示屏幕上的光学材料的发光效率发生变化,进而导致显示屏幕的亮度衰减等现象。例如,随着显示屏幕的使用时间的增长,光学材料的发光效率变低,进而导致显示屏幕的亮度衰减;随着显示屏幕的显示温度的升高,光学材料中的用于发出RGB三种颜色光的光学材料的发光效率降低的程度不同,进而导致显示屏幕显示的画面的颜色发生偏差。
本申请实施例中,驱动参数是用于驱动显示屏幕的像素点发光的参数,驱动参数能够指示对应的像素点发出的光的亮度。例如,驱动参数可以是施加给像素点的电压值,施加的电压值的不同,像素点的亮度不同。由于显示屏幕上的光学材料的发光效率与显示屏幕的状态有关,因此,根据同一驱动参数点亮不同状态下的像素点的亮度可能不同。
相关技术中,对于待显示的画面,根据该画面的画面数据确定该画面对应的多个像素值,一个像素值对应一个驱动参数,无论显示屏幕的状态如何,均基于该驱动参数显示画面,但是同一驱动参数在不同状态下指示的亮度不同,因此,显示屏幕在不同状态下基于同一驱动参数显示同一画面的显示效果不同。以驱动参数是施加给像素点的电压,状态信息为使用时间为例,施加的电压不变,随着使用时间的增长,显示屏幕的发光效率降低,显示亮度也随之降低。
本申请实施例提供了一种屏幕显示的控制方法,请参考图1,其示出了本申请实施例提供的屏幕显示的控制方法实施环境的示意图。该实施环境可以包括:计算机设备101和显示屏幕102,计算机设备101和显示屏幕102通过有线或无线进行连接。可选地,显示屏幕102可以为安装在计算机设备101上的屏幕,在该情况下,显示屏幕102是计算机设备101的一部分。
本申请实施例不对计算机设备101的类型进行限定,例如,计算机设备101可以为终端,也可以为服务器。可选地,终端可以是任何一种可与用户通过键盘、触摸板、触摸屏、遥控器、语音交互或手写设备等一种或多种方式进行人机交互的电子产品,例如PC(Personal Computer,个人计算机)、手机、智能手机、PDA(Personal Digital Assistant,个人数字助手)、可穿戴设备、PPC(Pocket PC,掌上电脑)、平板电脑、智能车机、智能电视、智能音箱等。服务器可以是一台服务器,也可以是由多台服务器组成的服务器集群,或者是一个云计算服务中心。
本申请实施例不对显示屏幕102的类型进行限定,例如,显示屏幕102可以是LED(Light Emitting Diode,发光二极管)屏幕或者LCD(Liquid Crystal Display,液晶显示器)屏幕等。
本领域技术人员应能理解上述计算机设备101和显示屏幕102仅为举例,其他现有的或今后可能出现的计算机设备101和显示屏幕102如可适用于本申请,也应包含在本申请保护范围以内,并在此以引用方式包含于此。
参见图2,图2为本申请实施例提供的一种屏幕显示的控制方法的流程图。以计算机设备执行该方法为例进行说明,该计算机设备连接有显示屏幕。例如,计算机设备可以为图1所示的计算机设备101,显示屏幕可以为图1所示的显示屏幕102。如图2所示,该屏幕显示的控制方法包括但不限于如下步骤201-步骤 203。
步骤201,获取显示屏幕待显示的画面的多个像素值,多个像素值与显示屏幕上的多个像素点一一对应。
本申请实施例不对显示屏幕的类型或规格进行限定,例如,显示屏幕的类型可以为LED屏幕或LCD屏幕等,显示屏幕规格可以为23英寸、24英寸或27英寸等。显示屏幕包括多个像素点,通过点亮多个像素点使得显示屏幕能够显示画面。一个像素点对应一个像素值,即多个像素值与多个像素点一一对应,像素值能够指示对应像素点的显示效果。例如,若像素值是(255,255,255),则该像素值对应的像素点发出白光。
可选地,获取显示屏幕待显示的画面的多个像素值的方式可以为,从源端提取该待显示的画面的多个像素值,或者,根据待显示的画面的画面数据生成该多个像素值。其中,源端可以是计算机设备的内存、计算机设备连接的外部存储设备或者网络等。
步骤202,基于多个像素值和显示屏幕的状态信息,确定多个像素点在状态信息指示的状态下分别对应的驱动参数,任一像素点的驱动参数指示任一像素点的亮度,任一像素点在不同状态下对应的驱动参数指示的亮度满足亮度要求。
在本申请实施例中,像素值能够指示像素点的显示效果是指,基于像素点的像素值确定像素点的驱动参数,根据像素点的驱动参数来点亮像素点,像素点的发光亮度由该驱动参数和像素点的发光材料共同决定,像素点的发光材料受显示屏幕的状态影响。因此,对于同一像素值,需要根据不同的状态信息确定不同的驱动参数,以使在不同状态下像素点的发光亮度均满足亮度要求。其中,像素点的驱动参数可以是施加给像素点的电流值或者是施加给像素点的电压值等,本申请实施例对此不做限定。
针对显示屏幕的同一状态,任一像素点的驱动参数指示任一像素点的亮度。示例性地,以驱动参数是施加给像素点的电压值为例进行说明,施加给像素点的电压为10v(volt,伏特),该像素点基于10v电压点亮的亮度为10nit(尼特),若施加给该像素点的电压为12v,则该像素点基于12v电压点亮的亮度为12nit。也可以说是施加给像素点的电压值与像素点的亮度正相关。
显示屏幕的状态不同导致显示屏幕的光学材料的发光效率不同,即在第一 种状态下光学材料的发光效率可能是该光学材料的初始发光效率的100%,在第二种状态下该光学材料的发光效率可能是该光学材料的初始发光效率的80%。初始发光效率可以认为是该光学材料在最理想状态下的发光效率。因此,若在第一种状态下向包含该光学材料的像素点施加10v电压,则该像素点可能发出的亮度为10nit。若在第二种状态下向包含该光学材料的像素点施加10v电压,由于在第二种状态下该光学材料的发光效率是该光学材料的初始发光效率的80%,则该像素点可能发出的亮度为8nit。由此,在不同状态下施加相同的电压值即相同的驱动参数,像素点发出的光的亮度不同。
针对在不同状态下施加相同的电压值,像素点发出的光的亮度不同的情况,需要在不同状态下施加不同的电压值使得像素点发出的光的亮度相同,也即发出的光的亮度满足亮度要求。以上述第二种状态下为例,若施加的电压值为12.5v,则对应的像素点的亮度可能为10nit。因此,需要基于多个像素值和显示屏幕的状态信息,确定多个像素点在状态信息指示的状态下分别对应的驱动参数,以使多个像素点在不同状态下对应的驱动参数指示的亮度均满足亮度要求,进而使得在不同状态下显示同一画面的显示效果大致相同。其中,本申请实施例的显示效果即是指亮度或颜色等。
不同状态下显示同一画面的显示效果大致相同可以理解为不同状态下显示同一画面的亮度相同,也可以理解为任一像素点在不同状态下对应的驱动参数指示的亮度满足亮度要求。在本申请实施例中,满足亮度要求可以是指与用于确定驱动参数的像素值期望达到的亮度相匹配,相匹配包括相同或者差值在阈值范围内,阈值范围根据应用场景灵活调整,例如,阈值范围为[1nit,-1nit]。
示例性地,以任一像素点的像素值为(255,255,255)为例,该像素值指示期望达到的亮度为10nit,在显示屏幕的参考状态下,直接基于该像素值确定驱动参数,按照该驱动参数点亮任一像素点的亮度为10nit,即任一像素点在参考状态下的亮度满足亮度要求。参考状态可以是指显示屏幕出厂时的标准状态,以状态信息包括显示时长和显示温度为例,参考状态可以是指显示时长小于时长阈值且显示温度为常温。时长阈值可以根据应用场景灵活调整,例如,1000小时,常温可以是指25℃(摄氏度)-30℃。
若显示屏幕的状态不为参考状态,则需要考虑到显示屏幕的状态变化对显示屏幕的光学材料的发光效率的影响,进而需要基于该像素值和状态信息共同 确定驱动参数,若按照该共同确定的驱动参数点亮任一像素点的亮度在[9nit,11nit]的范围内,则确定任一像素点在参考状态发生变化后的亮度满足亮度要求。由此,使得像素点在发光效率受到影响的情况下发出的光的亮度与发光效率未受到影响的情况下发出的光的亮度相匹配。
也就是说,任一像素点在不同状态下对应的驱动参数指示的亮度满足亮度要求,指的是在不同状态下基于同一像素值点亮同一像素点,该同一像素点的亮度偏差在偏差阈值范围内,差阈值范围可以根据应用场景灵活调整。例如,像素值为255,差阈值范围为2nit,在第一状态下,像素值255对应第一驱动参数,以第一驱动参数点亮像素点得到第一亮度,第一亮度为9.8nit,在第二状态下,像素值255对应第二驱动参数,以第二驱动参数点亮像素点得到第二亮度,第二亮度为9.9nit。第一亮度与第二亮度的亮度偏差为0.1nit,0.1nit小于差阈值范围,则确定该像素点在不同状态下对应的驱动参数指示的亮度满足亮度要求。
在本申请实施例中,状态信息即显示屏幕的状态的数值化体现,可选地,状态信息包括显示时长、显示温度、显示亮度或显示频率中的至少一个。其中,显示时长是指显示屏幕显示画面所使用的总时长,显示温度是指显示屏幕的发光材料所达到的温度,显示亮度是是显示屏幕的整体亮度等级,例如,夜间模式整体显示亮度较低,显示频率是指显示屏幕的刷新频率,即显示屏幕显示的画面每秒刷新的次数。例如,显示时长1000小时,则指示该显示屏幕已使用了1000小时。由于显示屏幕的光学材料的特性,显示屏幕的使用时间越长显示屏幕的光学材料的发光效率越低。
本申请实施例不对状态信息的获取方式进行限定。以显示时长为例,可以在显示屏幕中设置一个计时器,计算机设备读取显示屏幕中的计时器记录的显示时长,或者,在显示屏幕连接计算机设备时,计算机设备记录显示屏幕的显示时长。以显示温度为例,可以在显示屏幕中设置一个温度计,计算机设备读取显示屏幕中的温度计记录的显示温度。
在一种可能的实施方式中,以状态信息包括显示时长为例;基于多个像素值和显示屏幕的状态信息,确定多个像素点在状态信息指示的状态下分别对应的驱动参数的过程可以包括但不限于如下步骤11-步骤13。
步骤11,在多个时长分别对应的像素补偿值中确定显示时长对应的像素补偿值,任一时长对应的像素补偿值指示多个像素点使用任一时长后产生的亮度 衰减程度。
参见图3所示的一种显示时长与发光效率的对应关系示意图,随着显示屏幕的显示时长的增长,显示屏幕上像素点的光学材料的发光效率降低。图3中以灰阶来表示发光效率的降低,灰阶指的是亮暗之间的亮度变化等级。例如,一个像素点被设计为有256个亮度等级,随着亮度等级的升高,亮度越高,随着显示时长的增长发光效率降低20个灰阶,即以原第256灰阶对应施加的电压点亮像素点,像素点发出的光的亮度等级是第236灰阶的亮度。
以同一驱动参数点亮像素点,像素点的亮度降低。例如,在发光效率未降低的情况下,以驱动参数b200点亮像素点,像素点的亮度为c200,在发光效率已降低的情况下,以驱动参数b200点亮像素点,像素点的亮度可能是c180。因此,在发光效率已降低的情况下,需要提高驱动参数,以提高后的驱动参数点亮该像素点,使得像素点的亮度与发光效率未降低的情况下的亮度一致。例如,在发光效率已降低的情况下,以驱动参数b220点亮像素点,像素点的亮度是c200,与发光效率未降低的情况下,以驱动参数b200点亮像素点的亮度一致。
其中,驱动参数以b加数字的方式进行表示,b后面的数字与驱动参数的实际值成正比,例如,若驱动参数为电压值,则b1代表的电压值小于b2代表的电压值。像素点的亮度以c加数字的方式进行表示,c后面的数字与亮度成正比,例如,c1代表的亮度小于c2代表的亮度。
在发光效率已降低的情况下,驱动参数b200对应的像素值是200,显示gamma值是a200。在此种实施方式中,原像素值200对应的像素点的亮度不能达到c200,因此为了使原像素值对应的像素点的亮度达到c200,需要对原像素值进行补偿,得到补偿后的像素值,以补偿后的像素值和补偿后的像素值对应的显示gamma值确定的驱动参数点亮像素点,使得像素点的亮度与原像素值指示的亮度一致。
本申请实施例中,基于显示时长确定显示时长对应的像素补偿值,以像素补偿值对原像素值进行补偿,得到补偿后的像素值。其中,显示时长与补偿像素值的对应关系是提前根据经验设定好的。例如,参见图4所示的多个时长与像素补偿值的对应关系示意图,显示时长在0-10000小时对应的补偿像素值为8,显示时长在10000-30000小时对应的补偿像素值为16,显示时长在30000-40000小时对应的补偿像素值为20。
步骤12,基于显示时长对应的像素补偿值分别对多个像素值进行补偿,获取补偿后的多个像素值。
本申请实施例不对基于像素补偿值对像素值进行补偿,得到补偿后的像素值的方式进行限定。可选地,基于显示时长对应的像素补偿值分别对多个像素值进行补偿,获取补偿后的多个像素值可以包括:对于多个像素值中的任一像素值,将任一像素值与像素补偿值的和作为补偿后的任一像素值。
或者,基于显示时长对应的像素补偿值分别对多个像素值进行补偿,获取补偿后的多个像素值也可以包括:基于显示时长对应的像素补偿值和像素参考值确定补偿比例系数;对于多个像素值中的任一像素值,确定任一像素值与补偿比例系数的乘积,将乘积作为补偿后的任一像素值。
此种实施方式中,像素参考值是像素值可选择的范围中的最大像素值,例如,像素值可选择的范围是0-255的情况下,参考像素值为255。基于显示时长对应的像素补偿值和像素参考值确定补偿比例系数的方式本申请实施例不做限定,显示时长对应的像素补偿值、像素参考值与补偿比例系数之间满足如下公式1的关系。
A÷(A-B)=X        公式1
其中,A为像素参考值,B为像素补偿值,X为补偿比例系数,(A-B)指示现像素值与原像素值之间的映射关系,现像素值是指亮度衰减后的像素值,原像素值是指亮度衰减前的像素值。例如,A为255,B为20,则指示现像素值255对应的亮度衰减到与原像素值235对应的亮度,即现像素值255对应的亮度为c235。因此,若像素值为235,则需要将235补偿到255,基于补偿后的像素值255得到对应的驱动参数b255,以驱动参数b255点亮像素点,才能使得像素点发出的光的亮度为像素值235指示的亮度c235。
步骤13,根据补偿后的多个像素值和显示gamma值,确定多个像素点在状态信息指示的状态下分别对应的驱动参数。
由上述内容可知,显示屏幕的像素点是基于驱动参数发光的,即像素点的亮度与驱动参数一一对应。像素值指示的是像素点的亮度,像素值需要转化为驱动参数来点亮像素点。在同一状态下,像素值与驱动参数一一对应,像素值与驱动参数的对应关系为,像素值和像素值对应的显示gamma值确定一个驱动参数,本申请实施例不限定像素值和像素值对应的显示gamma值确定驱动参数 的方式,例如,像素值点乘像素值对应的显示gamma值后得到驱动参数。
在显示面板设计制造的过程中,像素值与像素值对应的显示gamma值是被配置好的,例如,像素值255对应的显示gamma值是a255,由像素值和显示gamma值确定的驱动参数为b255,由驱动参数b255点亮像素点,像素点的亮度为c255。其中,显示gamma值以a加数字的方式进行表示,a后面的数字与显示gamma值的实际值成正比,例如,a1代表的显示gamma值小于a2代表的显示gamma值。
对于步骤12中基于该补偿比例系数对像素值进行补偿的过程,像素值为235,补偿比例系数为255/235,像素值与补偿比例系数的乘积为255,将乘积255作为补偿后的像素值。通过补偿后的像素值255和补偿后的像素值255对应的显示gamma值a255,得到驱动参数b255,以驱动参数b255点亮像素点,使得像素点发出的光的亮度为c235,c235为像素值235指示的期望发光的亮度。
为了便于理解,以图5所示的一种对像素值进行补偿的场景示意图为例进行说明。对于像素值进行数据映射,数据映射即将像素值映射为补偿后的像素值。补偿后的像素值进入亮度减少补偿,亮度减少补偿用于提供显示时长。补偿后的像素值和显示时长进行后续的统计范围调整,统计范围调整即基于显示时长确定像素补偿值。补偿后的像素值是基于上一显示时长对应的上一像素补偿值确定的,若统计范围调整确定的像素补偿值和上一像素补偿值一致,则直接输出补偿后的像素值,若统计范围调整确定的像素补偿值和上一像素补偿值不一致,则以统计范围调整确定的像素补偿值重新对像素进行补偿。
由此,根据上述步骤11-步骤13可知,通过动态获取不同显示时长对应的像素补偿值,使得随着显示时长的增加可以动态调整像素值的补偿范围,即无论显示时长增加到多长,本申请实施例提供的方法均能够为根据对应的像素补偿值进行补偿。
在一种可能的实施方式中,以状态信息包括显示时长、显示温度、显示亮度或显示频率中的至少一个为例,显示屏幕包括第一gamma值和第二gamma值;基于多个像素值和显示屏幕的状态信息,确定多个像素点在状态信息指示的状态下分别对应的驱动参数的过程包括但不限于如下步骤21-步骤23。
步骤21,对于多个像素点中的任一像素点,根据显示时长、显示温度、显示亮度或显示频率中的至少一个以及任一像素点对应的像素值,确定任一像素 点对应的gamma调整系数。
显示屏幕的第一gamma值和第二gamma值是预先设定在显示屏幕中的,第一gamma值和第二gamma值用于在不同状态下确定不同的驱动参数,例如,在黑暗环境下相比明亮环境下基于同一像素值得到的驱动参数更低,从而使得像素点的亮度更低,进而避免过高的亮度损伤用户的眼睛。示例性地,显示屏幕为LTPO(Low Temperature Polycrystalline Oxide,低温多晶氧化物)OLED(Organic Light-Emitting Diode,有机发光二极管)。
本申请实施例以第一gamma值和第二gamma值作为显示gamma值的计算参数,即显示gamma值基于显示屏幕的状态的不同可在第一gamma值和第二gamma值之间动态调整。参见图6所示的显示gamma的取值范围示意图,其中,不同灰阶下显示gamma值是不同的,显示gamma针对每一个灰阶的取值范围在第一gamma值和第二gamma值之间。
显示屏幕的状态信息指示显示屏幕所处的不同状态,一个状态对应一个gamma调整系数,该gamma调整系数用于确定该状态对应的显示gamma值。此外,如图6所示在同一显示亮度下不同灰阶对应的显示gamma值也不同,其中,同一显示亮度指的是显示屏幕的整体亮度固定,可以理解为同一显示亮度下分为256个灰阶,灰阶指示不同的亮度等级,不同显示亮度下同一灰阶的亮度随着显示亮度的增大而增大,同一显示亮度下不同灰阶的亮度随着灰阶的增大而增大。即同一显示亮度下不同灰阶对应的gamma调整系数不同,也就是不同的亮度等级下gamma调整系数不同,不同亮度等级体现在像素值上就是像素值的大小不同,例如,在同一显示亮度下像素值为10指示的像素点的亮度高于像素值为1指示的像素点的亮度。
同一显示亮度下,像素值的不同对显示屏幕的状态的影响不同,例如,在同一显示亮度下,某一像素点以像素值为255发光和该像素点以像素值为100发光对老化的影响程度不同。以像素值为255发光相比以像素值为100发光老化程度更高,因此,在确定gamma调整系数时还需要考虑像素值的影响。
在一种可能的实施方式中,根据显示时长、显示温度、显示亮度或显示频率中的至少一个以及任一像素点对应的像素值,确定任一像素点对应的gamma调整系数,包括:将显示时长、显示温度、显示亮度或显示频率中的至少一个以及任一像素点对应的像素值输入补偿模型,根据补偿模型的输出结果确定 gamma调整系数,补偿模型根据不同像素值在不同状态信息下的gamma校准值之间的偏差确定。
补偿模型是预先建立好的,本申请实施例不对补偿模型的类型进行限定,可以是表格的形式或者函数图的形式。针对补偿模型根据不同像素值在不同状态信息下的gamma校准值之间的偏差确定的,即在任一像素值在任一状态信息下进行gamma校准,基于不同像素值在不同状态信息下的gamma校准值之间的偏差确定gamma校准值与不同像素值和不同状态信息之间的关系。
参见图7所示的一种显示温度与gamma校准值的偏差之间的关系示意图,随着显示温度的升高gamma校准值偏差增大,也即随着显示温度的升高对像素点的亮度的影响增大。参见图8所示的一种显示时长与gamma校准值的偏差之间的关系示意图,随着显示时长的增大gamma校准值偏差增大,也即随着显示时长的增大对像素点的亮度的影响增大。
参见图9所示的一种显示亮度与gamma校准值的偏差之间的关系示意图。其中,gamma0可以理解为某一参考状态下的显示gamma值,参考状态可自由定义,例如,25℃为参考状态等。针对同一gamma0,在不同显示亮度下gamma校准值的偏差不同。
由上述图7、图8和图9可确定不同的状态信息对gamma校准值,即显示gamma值的影响,同上显示频率同样对显示gamma值存在影响。因此,可基于显示时长、显示温度、显示亮度或显示频率中的至少一个以及任一像素点对应的像素值对显示gamma值的影响程度建立补偿模型,影响程度可以以数值的方式体现。即补偿模型能够指示在某一状态下的gamma调整系数。
示例性地,可基于显示时长、显示温度、显示亮度和显示频率以及任一像素点对应的像素值对显示gamma值的影响程度建立补偿模型。同时考虑显示时长、显示温度、显示亮度和显示频率以及任一像素点对应的像素值对显示gamma值的影响程度能够使得建立的补偿模型更加准确,可以理解为每考虑一种状态信息能够更加准确的对应每一种场景。补偿模型可以表格的形式或者图谱的形式,将状态信息输入补偿模型,补偿模型能够输出该状态信息指示的状态对应的gamma调整系数。不同状态信息对最终输出的gamma调整系数的确定所占的权重比例可以相同也可以不同,本申请实施例对此不做限定。
对于补偿模型是根据显示时长、显示温度、显示亮度和显示频率以及任一 像素点对应的像素值对显示gamma值的影响程度建立的情况,输入显示时长、显示温度、显示亮度和显示频率以及任一像素点对应的像素值才能够确定该状态信息指示的状态对应的gamma调整系数。若输入的是状态信息的一部分,可能无法得出gamma调整系数。或者除输入的状态信息的一部分之外的其它状态信息默认为参考状态信息作为输入量,得出gamma调整系数,该情况下得出gamma调整系数可能准确性较低。参考状态信息可以是提前设置好的,例如,若不输入显示温度,则可默认显示温度为25℃等。
在一种可能的实施方式中,状态信息能够指示历史状态信息和当前状态信息,历史状态信息用于确定显示屏幕的老化程度,例如,一个显示屏幕以被设置的最高亮度点亮1小时和以最高亮度的一半点亮一小时,显示屏幕的老化程度是不同的。当前状态信息用于确定显示屏幕所处的状态,例如,显示屏幕以同一驱动参数驱动的情况下,若显示温度不同,像素点的亮度也会不同。因此在确定gamma调整系数时需要同时考虑历史状态信息和当前状态信息的影响。
参见图10所示的一种gamma调整系数的确定过程示意图,其中,RAM(Random Access Memory,随机存取存储器)用于临时存储计算机设备正在运行的数据和程序,但是掉电后会丢失数据。Flash(快闪)存储器在计算机设备掉电后不会丢失数据。计算机设备读取Flash存储器中存储的数据需要通过RAM。Flash存储器和RAM仅为举例说明,其它现有的能够实现对应功能的存储器也可对Flash存储器和RAM进行替换。老化预测和确定gamma调整系数可以在计算机设备的处理器中进行。为了便于说明,以虚拟模块完成对老化预测过程和确定gamma调整系数过程为例,即老化预测模块用于老化预测,确定gamma调整系数模块用于确定gamma调整系数。
老化预测模块对于显示屏幕运行过程中每一时刻的当前状态信息进行采集,通过RAM存储到Flash存储器中,以便在进行老化预测时能够通过RAM读取Flash存储器中存储的数据,即历史状态信息,从而确定显示屏幕的老化程度,老化预测模块基于历史状态信息确定老化数值,老化数值能够指示显示屏幕的老化程度。老化预测模块将老化数值发送给确定gamma调整系数模块,确定gamma调整系数模块基于老化数值指示的显示屏幕的老化程度和当前状态信息确定当前状态下的gamma调整系数。其中,确定老化数值和确定当前状态下的gamma调整系数均可通过对应的模型进行。本申请实施例不对模型的类型进行 限定。
步骤22,根据第一gamma值、第二gamma值与gamma调整系数获取任一像素点对应的显示gamma值。
可选地,根据第一gamma值、第二gamma值与gamma调整系数获取任一像素点对应的显示gamma值的过程可通过如下公式2执行。其中,α为gamma调整系数,由公式2可知,随着gamma调整系数的变化,显示gamma值在第一gamma值和第二gamma值形成的闭区间范围内变化。
显示gamma值=(1-α)×第一gamma值+α×第二gamma值公式2
示例性地,gamma校准值之间的偏差越大指示两个gamma校准值对应的显示屏幕的状态差距越大,以该两个gamma校准值对应的显示屏幕的状态中有一个状态是参考状态为例,可认为参考状态对应的显示gamma值为第一gamma值,即gamma调整系数为0。由此另一显示屏幕的状态与参考状态差距越大,gamma调整系数越大,即在其中一个gamma校准值为参考状态下的gamma校准值的情况下,gamma校准值之间的偏差越大另一状态对应的gamma调整系数越大。其中,第一gamma值的系数为(1-α),在其中一个gamma校准值为参考状态下的gamma校准值的情况下,gamma校准值之间的偏差越大另一状态对应的第一gamma值的系数越小。
步骤23,根据任一像素点的像素值和任一像素点对应的显示gamma值,确定任一像素点在状态信息指示的状态下对应的驱动参数。
在本申请实施例中,根据任一像素点的像素值和任一像素点对应的显示gamma值,确定任一像素点在状态信息指示的状态下对应的驱动参数的过程可参见步骤13中的相关描述,此处不再赘述。
由此,根据上述步骤21-步骤23可知,通过动态调节显示gamma值的方式,使得显示屏幕在状态发生变化的情况下的显示亮度满足亮度要求,由于显示亮度满足亮度要求,而发光颜色由每个RGB像素点的亮度确定,进而使得显示屏幕在状态发生变化的情况下的颜色不会发生偏移,改善状态变化导致的色偏问题。
在一种可能的实施方式中,基于多个像素值和显示屏幕的状态信息,确定多个像素点在状态信息指示的状态下分别对应的驱动参数的过程还可以包括:在多个时长分别对应的像素补偿值中确定显示时长对应的像素补偿值;基于显 示时长对应的像素补偿值分别对多个像素值进行补偿,获取补偿后的多个像素值;对于多个像素点中的任一像素点,根据显示温度、显示亮度或显示频率中的至少一个以及任一像素点对应的补偿后的像素值,确定任一像素点对应的gamma调整系数;根据第一gamma值、第二gamma值与gamma调整系数获取任一像素点对应的显示gamma值;根据任一像素点对应的补偿后的像素值和任一像素点对应的显示gamma值,确定任一像素点在状态信息指示的状态下对应的驱动参数。
该种方式下,先根据步骤11-步骤12的方式对像素值进行补偿,再根据步骤21-步骤22的方式调整显示gamma值,最终根据补偿后的像素值以及调整后的显示gamma值进行画面显示。该种方式下的实施过程可参见上述步骤11-步骤13以及步骤21-步骤23的实施方式,此处不再赘述。
步骤203,按照多个像素点分别对应的驱动参数点亮多个像素点,以使显示屏幕显示画面。
一个像素点对应一个驱动参数,以驱动参数点亮多个像素点可以理解为计算机设备基于驱动参数对驱动参数对应的像素点时间驱动参数指示的电压,从而点亮多个像素点,多个像素点点亮完成画面的显示。
示例性地,一个像素点可能包括R子像素点、G子像素点和B子像素点,每个子像素点中的光学材料有所不同,光学材料不同导致相同状态对光学材料发光效率的影响不同。参见图11所示的不同光学材料的gamma校准值偏差情况示意图,其中,gamma校准值偏差是三种光学材料的整体偏差,但是不同光学材料的单个的gamma校准值偏差不同。
以相同状态下R子像素点的光学材料相比G子像素点的光学材料衰减程度更高为例,相同状态下R子像素点对应的补偿比例系数相比G子像素点对应的补偿比例系数更大,使得R子像素点对应的显示gamma值越大,从而补偿R子像素点光学材料相对于G子像素点的光学材料更高的衰减程度。
在一种可能的实施方式中,任一像素点包括R子像素点、G子像素点和B子像素点,则任一像素点的像素值包括R子像素值、G子像素值和B子像素值,任一像素点的驱动参数包括R分量驱动参数、G分量驱动参数和B分量驱动参数。
基于多个像素值和显示屏幕的状态信息确定,多个像素点在状态信息指示的状态下分别对应的驱动参数的过程包括:基于多个R子像素值和显示屏幕的 状态信息,确定多个R子像素点在状态信息指示的状态下分别对应的R分量驱动参数,基于多个G子像素值和显示屏幕的状态信息,确定多个G子像素点在状态信息指示的状态下分别对应的G分量驱动参数,基于多个B子像素值和显示屏幕的状态信息,确定多个B子像素点在状态信息指示的状态下分别对应的B分量驱动参数。其中,基于多个子像素值和显示屏幕的状态信息,确定多个子像素点在状态信息指示的状态下分别对应的分量驱动参数的过程,可参见步骤202中基于多个像素值和显示屏幕的状态信息,确定多个像素点在状态信息指示的状态下分别对应的驱动参数的过程,此处不再赘述。
按照多个像素点分别对应的驱动参数点亮多个像素点的过程包括:按照多个R子像素点分别对应的R分量驱动参数点亮多个R子像素点,按照多个G子像素点分别对应的G分量驱动参数点亮多个G子像素点,按照多个B子像素点分别对应的B分量驱动参数点亮多个B子像素点。其中,按照多个子像素点分别对应的分量驱动参数点亮多个子像素点的过程,可参见步骤203中按照多个像素点分别对应的驱动参数点亮多个像素点的过程,此处不再赘述。
综上,本申请实施例提供的屏幕显示的控制方法,在确定显示屏幕的像素点的驱动参数时考虑到了显示屏幕的像素点所处的状态对像素点的发光效率的影响,结合状态信息来确定像素点对应的驱动参数。由此,使得在不同状态下通过不同的状态信息确定的驱动参数所指示的亮度均满足亮度要求,避免由状态发生变化导致的显示屏幕的亮度衰减问题,提升了用户体验。此外,对于像素点分为R、G和B三种子像素点进行考虑,不同子像素点采用不同的分量驱动参数,使得补偿更加准确,提高了显示效果。
