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,并不设置为限定本申请。
本申请实施例的主要解决方案是:
在显示面板进行伽马值调整后,获取调整后的伽马值以及面板信息;
根据所述伽马值以及面板信息生成预设格式的调整文件;
将所述调整文件存储至预设的存储路径,以在伽马值判等时由所述存储路径提取所述调整文件进行判等。
由于现有技术中伽马调节以及伽马判等是分开的,伽马判等需要对伽马调节得到的伽马曲线进行判等,但由于伽马调节以及伽马判等两个系统往往是分开的,往往无法自动提取伽马曲线进行判等,需要用户手动输入gamma曲线进行判等,导致对显示面板的出厂设置效率低。
本申请提供一种解决方案,在显示面板进行伽马值调整后,根据伽马值以及面板信息直接生成预设格式的调整文件,并将调整文件存储至预设的存储路径,在伽马判等时直接由预设存储路径提取伽马值提取调整文件进行判等,不用用户手动输入伽马值进行判等,提高显示面板的出厂设置效率。
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伽马的调节。
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。
在图1所示的终端中,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:

在显示面板进行伽马值判等后,获取判等结果以及进行判等的面板的面板信息;以及
将所述判等结果与所述面板信息关联保存。
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:

将所述伽马平均值作为所述伽马曲线的伽马值。
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,在显示面板进行伽马值调整后,获取调整后的伽马值以及面板信息;
面板信息可包括面板标识如面板的ID(标识)或者面板型号等,面板标识可通过扫描显示面板上的图形码(如二维码或者条形码)得到,也可由测试人员手动输入。可以理解的是,面板信息也可包括面板的调整时间点。
步骤S20,根据所述伽马值以及面板信息生成预设格式的调整文件;
预设格式的调整文件可为以面板标识以及调整时间命名的文本文件,读取该文本文件即可得到伽马值;通过面板信息和调整时间命名调整文件,则在判等时可通过调整文件的命名快速获取到当前进行判等的显示面板对应的调整文件,该文本文件可为TXT格式的文本文件。
步骤S30,将所述调整文件存储至预设的存储路径,以在伽马值判等时由所述存储路径提取所述调整文件进行判等。
在存储调整文件是可按照存储时间依次存储,也可按照显示面板的型号分类存储,并按照型号对存储的文件夹命名,在提取调整文件时,可直接获取显示面板的型号信息,根据型号信息获取对应的存储文件夹,并在文件夹中按照面板信息获取对应的调整文件。
在所述存储路径的剩余存储容量小于预设阈值时,可按照存储时间删除预设数量的调整文件;或者,每隔预设时间间隔删除预设数量的存储文件。
本实施例公开的显示面板的伽马值调节方法,在显示面板进行伽马值调整后,根据伽马值以及面板信息直接生成预设格式的调整文件,并将调整文件存储至预设的存储路径,在伽马判等时直接由预设存储路径提取伽马值提取调整文件进行判等,不用用户手动输入伽马值进行判等,提高显示面板的出厂设置效率。
可选地在一实施例中,参照图3,基于一实施例提出本申请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S30之后包括:
步骤S40,在所述预设的存储路径中提取待判等的显示面板的所述调整文件;
步骤S50,获取所述调整文件中的伽马值;以及
步骤S60,判断所述伽马值是否在预设伽马值范围,以进行伽马值判等。
预设伽马值范围为2.0-2.4,在伽马值在预设伽马值范围时,判定伽马值调节成功,在伽马值不在预设伽马值范围时,判定伽马值调节失败,在成功时直接输出伽马曲线调节成功的提示信息,在失败时,直接输出调节失败的提示信息。
可以理解的是,可能会存在存储的伽马值被损坏或者存储失败的情况,在未获取到调整文件时,可输出调整文件不存在的提示信息。
在检测到显示面板的判等指令时,可获取待判等的显示面板的面板信息,并根据面板信息获取对应的调整文件,然后根据调整文件获取对应伽马值即,步骤S40包括,获取待判等的显示面板的面板信息;根据所述面板信息提取对应的所述调整文件。可以理解的是,调用过的所述调整文件可添加已调用标识,在删除时,可优先删除有已调用标识的调整文件。
在显示面板进行伽马值判等后,获取判等结果以及进行判等的面板的面板信息;将所述判等结果与所述面板信息关联保存。也可将所述判等结果与所述面板信息发送至服务器。
本实施例公开的技术方案中,直接由预设存储路径中获取调整文件进行伽马值判等,避免用户手动输入伽马值进行判等,提高判等的效率。
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,步骤S10之前,所述显示面板的伽马值调节方法还包括:
步骤S70,控制显示面板输出预设的各个灰阶的图片;
步骤S80,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;
步骤S90,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;以及
步骤S100,获取所述伽马曲线的伽马值。
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,对背光光源的输出电压进行调整。
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伽马寄存器的设定得到伽马电压。
在获取伽马曲线的伽马值时,可仅获取预设灰阶范围内的伽马平均值,如获取50-200灰阶区间内的伽马平均值,将该伽马平均值作为伽马曲线的伽马值进行判等。
此外,本申请还提出一种所述显示面板的伽马值调节装置包括至少一个处理器,以及存储设备,其中,所述存储器存储有可被所述至少一个处理器执行的计算机可执行指令,所述计算机可执行指令被所述至少一个处理器执行时,使得所述至少一个处理器执行以下电路中的步骤:
