具体实施方式
应当理解,此处所描述的具体实施例仅仅用以解释本申请,并不限定本申请。
本申请实施例的主要解决方案是:
控制进行伽马值调整后的显示面板输出预设的各个灰阶的图片;
采集各个灰阶的图片对应的亮度,并根据所述亮度计算伽马值;
对比计算得到的所述伽马值与预设伽马值范围以判定伽马值调整是否正确,其中,在计算得到的伽马值在所述预设伽马值范围内时,判定所述伽马值的调整正确
由于现有技术中在进行gamma值调节后将调节后的gamma值与标准值进行对比,以确定gamma调节是否成功,但该种方式并未进一步确定亮度标准,导致调整后的gamma值不够准确。
本申请提供一种解决方案,在进行伽马值调整后,控制进行伽马值调整后的显示面板输出预设的各个灰阶的图片,并采集各个灰阶的图片对应的亮度,根据采集的亮度计算伽马值,在计算得到的伽马值在所述预设伽马值范围内时,判定所述伽马值的调整正确,该方案重新根据计算伽马值以确定伽马调整的准确性,而不是直接确定最终的伽马值是否在预设范围,以使的调整后的伽马值更加准确。
如图1所示,图1是本申请实施例方案涉及的硬件运行环境的装置结构示意图。
本申请实施例装置可为显示面板或者其它终端,如电脑,在本实施例终端为电脑时,电脑通过数据线或者无线的方式与显示面板进行通信以实现gamma的调节。
如图1所示,该装置可以包括:处理器1001,通信总线1002以及存储器1003。其中,通信总线1002设置为实现这些组件之间的连接通信。存储器1003可以是高速RAM存储器,也可以是稳定的存储器(non-volatile memory),例如磁盘存储器。存储器1003可选的还可以是独立于前述处理器1001的存储装置。
本领域技术人员可以理解,图1中示出的终端结构并不构成对终端的限定,可以包括比图示更多或更少的部件,或者组合某些部件,或者不同的部件布置。
如图1所示,作为一种计算机存储介质的存储器1003中可以包括操作系统以及显示面板的伽马值调节程序。

采集各个灰阶的图片对应的亮度,并根据所述亮度计算伽马值;

可选地在一实施例中,处理器可以设置为调用存储器1003中存储的显示面板的伽马值调节程序,并执行以下操作:

在所述伽马曲线与标准伽马曲线之间存在误差时,调整伽马电压。
可选地在一实施例中,处理器可以设置为调用存储器1003中存储的显示面板的伽马值调节程序,并执行以下操作:
输出判定结果。
可选地在一实施例中,处理器可以设置为调用存储器1003中存储的显示面板的伽马值调节程序,并执行以下操作:
在判定伽马值调整失败时,返回执行所述控制进行伽马值调整后的显示面板输出预设的各个灰阶的图片的步骤。
参照图2,提出本申请显示面板的伽马值调节方法一实施例,在本实施例中显示面板的伽马值调节方法包括以下步骤:
步骤S10,控制进行伽马值调整后的显示面板输出预设的各个灰阶的图片;
显示面板的伽马值调整以及调整值的确认可以在同一个制程也可处于不同的制程,在已同一制程时可通过标识来标记伽马值是否进行调整,标识为1可认为已经调整,为0说明未调整。
预设的灰阶可白色以及黑色对应的灰阶,输出的图片为各个灰阶的纯色图片。
该灰阶图片可由与面板连接的控制器传输至面板,面板接收到该图片后进行显示,该控制器的图片可由服务器得到,控制器可先获取面板类型,服务器根据面板类型向控制器下发对应的图片。
步骤S20,采集各个灰阶的图片对应的亮度,并根据所述亮度计算伽马值;以及
步骤S30,对比计算得到的所述伽马值与预设伽马值范围以判定伽马值调整是否正确,其中,在计算得到的伽马值在所述预设伽马值范围内时,判定所述伽马值的调整正确。
亮度值可通过显示面板中的各个像素点的色彩值(如RGB值)得到,才加当前显示画面中各个像素点的色彩值,根据各个像素点的色彩值可得到当前显示画面的亮度。伽马值可根据亮度以及伽马电压得到,在检测到亮度时可直接根据检测得到的亮度值以及伽马电压计算伽马值,各个灰阶的亮度可分别计算。
预设伽马值范围为2.0-2.4, 在步骤S30之后,可输出伽马值的判定结果,在成功是直接输出伽马曲线调节成功的提示信息,在失败是,直接输出调节失败的提示信息。或者,可以理解的是,在判定伽马值调整失败时,返回执行所述控制进行伽马值调整后的显示面板输出预设的各个灰阶的图片的步骤,以对伽马值重新进行调节,在调节次数大于预设值时,输出调整失败的提示信息。
本实施了公开的技术方案中,在进行伽马值调整后,控制进行伽马值调整后的显示面板输出预设的各个灰阶的图片,并采集各个灰阶的图片对应的亮度,根据采集的亮度计算伽马值,在计算得到的伽马值在所述预设伽马值范围内时,判定所述伽马值的调整正确,该方案重新根据计算伽马值以确定伽马调整的准确性,而不是直接确定最终的伽马值是否在预设范围,以使的调整后的伽马值更加准确
可选地在一实施例中,基于一实施例提出本申请显示面板的伽马值调节方法另一实施例,在本实施例中,所述步骤S10之前还包括:
步骤S40,控制显示面板输出预设的各个灰阶的图片;
步骤S50,采集各个灰阶的图片对应的亮度,根据采集的亮度计算各个灰阶对应的伽马值;以及
步骤S60,根据计算得到的所述伽马值生成所述显示面板的伽马曲线。
控制器可依次传输255个灰阶的图片至显示屏,为避免检测点过多,可每隔预设灰阶数(如4个灰阶)作为一个检测点,并输出该监测点对应的灰阶的图片,显示面板在接收到图片后显示接收到的图片,并采集图片的亮度,该亮度了通过亮度仪或者检测软件检测得到,在检测到亮度后将亮度转换为透过率,将灰阶以百分比来表示,然后用取对数的方法求出个点对应的伽马值,在得到伽马值后若计算得到的伽马值不在2.0-2.4范围内,则可重新进行校正。
伽马曲线的坐标系为透过率与灰阶对应的坐标形成,则在计算得到伽马后在预设的坐标系中标记计算得到的所述伽马值,并连接各个所述伽马值形成伽马曲线。由于检测的图片有限,在连接伽马值后形成的曲线可能不够平滑,会出现拐点,此时可对拐点的部分进行平滑处理,平滑处理的方式可包括增加检测点的方式,根据增加的检测点计算得到的伽马值重现进行曲线的连接。
在进行伽马调整后,可能会存在部分伽马值不在预设范围内如2.0-2.4范围内,则在生成伽马曲线后,将所述伽马曲线与标准伽马曲线进行对比;在所述伽马曲线与标准伽马曲线之间存在误差时,对伽马芯片中的伽马电压输出进行调整。
在生成伽马曲线后,由标准灰阶以及标准伽马值可以计算出标准透过率,得到标准伽马曲线,将每个灰阶下的透过率与标准透过率进行比较则会得到透过率的偏移值,根据透过率的偏移值即可得到电压调整值,透过率过高则需要降低伽马电压,透过率过低则可增大伽马电压值。调整伽马电压可分为两种方式,对称电压调整方式和非对称电压调整方式,得到最终的伽马电压后可通过调节gamma芯片中的寄存器设定的电压,实现伽马电压的调整。
本实施例公开的技术方案中限定了伽马曲线的生成方式,直接根据检测的亮度以及对应的灰阶生成伽马曲线。
可选地在一实施例中,参照图4,基于第一或另一实施例提出本申请显示面板的伽马值调节方法再一实施例,在本实施例中,所述步骤S10之前还包括:
步骤S70,点亮显示面板的背光光源;以及
步骤S80,在显示面板的亮度稳定后,对所述显示面板进行画面检测;
在画面检测完成后,执行所述步骤S10,即控制显示面板输出预设的各个灰阶的图片。
画面检测可包括闪烁的检测,在检测结果不符合标准值时,对显示面板的显示参数进行调节,然后重新进行检测,在检测结果均符合标准值时,执行步骤S10。
本实施例限定了面板进行伽马曲线调节之前的其它调节过程,使得显示面板的显示更加稳定。
