Description

显示器的亮度匹配方法及显示器 技术领域
本申请涉及显示技术领域，尤其涉及一种显示器的亮度匹配方法及显示器。
 背景技术
由于液晶面板的处理技术有限，现有技术中无法消除LCD（即，Liquid Crystal Display）拼接屏之间的黑缝，而LED（即，Light-Emitting Diode）的四周不设置电路，可以达到无缝衔接的效果。因此，现有技术中在LCD拼接屏的拼缝中间加入LED过渡，以便有效消除LCD拼接屏之间的黑缝。
现有技术中，要保证LED与LCD显示效果的一致性是实现无缝衔接所要突破的重大难点之一。例如，在亮度方面，由于在LCD屏幕内，光线由背光板发出，经过液晶与偏光片的作用后进入人眼被感知，而LED发出的光线由于其自发光属性，能直接被人眼感知。因此，在未对LED及LCD亮度做处理的情况下，LED的亮度会远比LCD的亮度高。
现有技术中，一般采用逐点校正技术来调节LED屏的亮度。逐点校正技术可以通过对LED屏上的每个像素区域的亮度进行采集，给出相应的校正系数，并反馈给控制系统，以实现对于LED屏每个像素区域的差异性驱动。
然而，相关技术中以色度仪量测的LCD屏亮度为基准来调整LED屏的亮度存在误差。在实际工作过程中，以色度仪量测的LCD屏亮度为基准来调整的LED屏的亮度与肉眼实际观测到的LED亮度不一致。因此，如何保证LED与LCD显示效果的一致性是一个亟待解决的问题。

如图1所示，本申请实施例中的显示器可以包括至少一块第一显示面板以及至少一块第二显示面板，所述至少一块第一显示面板与所述至少一块第二显示面板相拼接。示例性的，所述第一显示面板可以是LCD屏，所述第二显示面板可以是LED屏。
在图1中，以所述显示器包括4块LCD屏以及4块LED屏为例，在LCD屏四周可设置至少一块LED屏，任意一块LED屏可设置在对应的两块LCD屏的缝隙处。例如，在图1中，LED屏12可以设置在LCD屏11的周围。可以理解，图1是示例性的，图1中的LCD屏以及LED屏可以沿四周向外延展，本申请对于显示器中LCD屏以及LED屏的拼接方式并不限定。
图2示出本申请实施例的显示器的亮度匹配方法的流程图。
如图2所示，在本申请实施例中，所述显示器的亮度匹配方法可包括：
步骤S10：获取校正仪器对所述第一显示面板的第一校正信息；
其中，所述校正仪器包括色度仪或光谱仪。色度仪或光谱仪均可以用于测量本申请实施例中的显示面板的亮度。利用色度仪或光谱仪测量所述显示面板的亮度，简单方便。可以理解，在实际应用中，还可以用其他设备或装置测量屏幕的亮度，本申请对于如何测量显示面板的亮度并不限定。
进一步地，获取校正仪器对所述第一显示面板的第一校正信息，包括：
步骤S101：在所述第二显示面板上显示与所述第一显示面板相同的显示画面；
步骤S102：获取校正仪器对所述第一显示面板的第一校正信息，其中，所述第一校正信息包括所述第一显示面板的第一显示亮度以及所述第二显示面板的第二显示亮度。
由于需要将第二显示面板的亮度与第一显示面板的亮度进行适配，因此可以先分别向第二显示面板以及第一显示面板输入相同的显示画面，以对比第二显示面板以及第一显示面板在显示同一显示画面时的亮度差异。所述显示画面可以是全白画面，也可以是全黑画面，或者是任意色彩的其他画面。通过在第二显示面板以及第一显示面板输入相同的显示画面，能够便于对比第二显示面板与第一显示面板的亮度差异，方便进行后续的校正。
以所述第一显示面板为LCD屏为例，任意一块所述第一显示面板可包括多个以行列形式排布的像素单元。每个像素单元可以包括三种不同类型的子像素单元，例如红色子像素单元、绿色子像素单元以及蓝色子像素单元。每个子像素单元可以用于显示红（即，R）、绿（即，G）或蓝（即，B）中的其他一种颜色。可以理解，子像素单元还可以有其他类型，例如白色子像素单元，本申请对于子像素单元的类型并不限定。
继续以所述第一显示面板为LCD屏为例，任意一块所述第一显示面板中，每个像素单元可以与一条数据线电连接，每行像素单元可以与一条扫描线连接。每个像素单元中可设置有薄膜晶体管。当一行像素单元对应的扫描线打开时，可以使该行像素单元中的薄膜晶体管全部处于导通状态，从而使得相应的数据线上的显示数据能够写入到对应的像素单元中，从而驱动显示面板进行显示。
进一步地，每个像素单元对应的显示数据可包括灰阶数据。例如，每个子像素单元可对应设置有一个灰阶。灰阶可以表示每一颜色从最暗到最亮之间的不同亮度层级。以8位灰阶为例，所述LCD屏的灰阶的表示范围为从0至255，共256个等级，最大灰阶为255。当然，对于不同类型的显示屏，灰阶的数量和表示方式可以不同。例如，灰阶也可以用10位二进制表示，此时灰阶的表示范围可以从0至1023。可以理解，本申请对于灰阶的数量和表示方式并不限定。
进一步地，所述第二显示面板的灰阶范围与所述第一显示面板的灰阶范围相同。示例性的，所述第二显示面板的灰阶范围也可以是0至255。当然，在实际应用中，根据具体情况的需要，所述第二显示面板的灰阶范围与所述第一显示面板的灰阶范围也可以不同。
步骤S20: 根据所述第一校正信息对所述第二显示面板的亮度进行第一次校正，得到所述第二显示面板的第一校正亮度；
其中，示例性的，本申请实施例的第一次校正可以采用逐点校正。具体的，在第一次校正过程中，可以采用逐点校正对第二显示面板上的每个像素单元的亮度进行采集，并对比相应的第一显示面板上的亮度（即，第一显示亮度），根据对应的第一显示面板上的亮度来对第二显示面板的亮度（即，第二显示亮度）进行校正，从而得到第一次校正后的所述第二显示面板的第一校正亮度。可以理解，所述第一次校正也可以采用其他的校正方法，本申请对于第一次校正的方法并不限定。
在实际应用过程中，经过第一次校正后的第一校正亮度会与实际观测到的第二显示面板的亮度存在误差，因此需要进行进一步校正，以消除利用第一次校正产生的第二显示面板的亮度与实际观测到的第二显示面板的亮度之间的误差。
步骤S30：获取用户对所述第二显示面板的第二校正信息；
其中，获取用户对所述第二显示面板的第二校正信息，包括：
步骤S301：获取所述第二显示面板的灰阶范围；
步骤S302：在所述第二显示面板的灰阶范围内选择至少一个绑点灰阶；
步骤S303：根据所述至少一个绑点灰阶获取用户对所述第二显示面板的第二校正信息，其中，所述第二校正信息包括所述至少一个绑点灰阶对应的所述第二显示面板的亮度。
进一步地，获取所述第二显示面板的灰阶范围。所述第二显示面板的灰阶范围可以是第二显示面板整体的灰阶范围，例如0-255灰阶；也可以是第二显示面板局部的灰阶范围，例如，在0-255灰阶中选取0-128灰阶作为所述第二显示面板的灰阶范围。可以理解，本申请对于所述第二显示面板的灰阶范围并不限定。
进一步地，所述第二显示面板的灰阶范围与所述第一显示面板的灰阶范围相同，在所述第二显示面板的灰阶范围内选择至少一个绑点灰阶。例如，在0至255灰阶中可以选择7个绑点灰阶。示例性的，可以设置绑点灰阶为16、32、48、64、80、96、112。每个绑点灰阶下可对应驱动第二显示面板显示与每个绑点灰阶对应的亮度。需要说明的是，由于第一显示面板与第二显示面板在对比亮度时输入的是相同的显示画面，因此对应于第二显示面板的绑点灰阶，第一显示面板中也可以对应设置有与第二显示面板相同的绑点灰阶。由于所述第二显示面板的灰阶范围与所述第一显示面板的灰阶范围相同，因此本申请实施例在处理灰阶与亮度的对应关系时，能够减少校正的复杂度，提高校正效率。
进一步地，根据所述至少一个绑点灰阶获取用户对所述第二显示面板的第二校正信息，其中，所述第二校正信息包括所述至少一个绑点灰阶对应的所述第二显示面板的亮度。即，第二校正信息与所述至少一个绑点灰阶相对应。此外，所述第二校正信息还可包括与所述至少一个绑点灰阶的所述第一显示面板的亮度。
通过在所述第二显示面板的灰阶范围内选择至少一个绑点灰阶，并根据所述至少一个绑点灰阶来进行第二次校正，本申请实施例能够在保证校正质量的同时，简化校正过程的工作量。
进一步地，获取用户对所述第二显示面板的第二校正信息，还可包括：
步骤S300：判断所述第二显示面板的第一校正亮度与实际观测的所述第二显示面板的亮度是否一致；
步骤S301：在所述第二显示面板的第一校正亮度与实际观测的所述第二显示面板的亮度不一致的情况下，获取用户对所述第二显示面板的第二校正信息。
其中，所述实际观测的所述第二显示面板的亮度可以是使用肉眼实际观测第二显示面板的亮度。
由于所述第二显示面板的第一校正亮度可以是经过第一次校正后理想的亮度，而实际观测的所述第二显示面板的亮度与所述第二显示面板的第一校正亮度会存在差异，因此通过将实际观测的所述第二显示面板的亮度与所述第二显示面板的第一校正亮度进行对比，本申请实施例能够避免经过校正的第二显示面板的亮度与实际观测的第二显示面板的亮度出现差异，提升第二显示面板与第一显示面板显示效果的一致性。
进一步地，判断所述第二显示面板的第一校正亮度与实际观测的所述第二显示面板的亮度是否一致，包括：
步骤S3001：基于所述第一校正亮度在所述第二显示面板上显示与所述第一显示面板相同的显示画面；
步骤S3002：根据所述第二显示面板的显示画面的亮度以及所述第一显示面板的显示画面的亮度判断所述第二显示面板的第一校正亮度与实际观测的所述第二显示面板的亮度是否一致。
具体的，可以先基于经过第一次校正后的第一校正亮度，在所述第二显示面板上显示与所述第一显示面板相同的显示画面，然后用肉眼观测经过第一次校正后的所述第二显示面板的亮度是否与实际观测的第二显示面板的亮度是否一致。若经过第一次校正后的所述第二显示面板的亮度是否与实际观测的第二显示面板的亮度一致，则表明经过第一次校正后的所述第二显示面板的亮度与实际情况相符合，可以不进行下一步的校正；若经过第一次校正后的所述第二显示面板的亮度是否与实际观测的第二显示面板的亮度不一致，则表明经过第一次校正后的所述第二显示面板的亮度与实际情况不相符合，需要进一步对第二显示面板的亮度进行进一步校正。
通过根据所述第二显示面板的显示画面的亮度以及所述第一显示面板的显示画面的亮度判断所述第二显示面板的第一校正亮度与实际观测的所述第二显示面板的亮度是否一致，本申请实施例能够保持第一次校正和第二次校正的一致性，简单方便，易于实现。
步骤S40：根据所述第二校正信息对所述第二显示面板的亮度进行第二次校正，得到所述第二显示面板的第二校正亮度；
其中，为了方便使用，可以使用肉眼根据所述第二校正信息对所述第二显示面板的亮度进行第二次校正，得到所述第二显示面板的第二校正亮度。也就是说，可以通过人工根据所述第二校正信息对所述第二显示面板的亮度进行第二次校正。当然，在实际使用中，也可以预先模拟人眼对于亮度的观测特性，利用仿人工设备来替代人工对所述第二显示面板的亮度进行第二次校正。可以理解，本申请对于使用何种设备对所述第二显示面板的亮度进行第二次校正进行校正并不限定。
示例性的，人工对所述至少一个绑点灰阶对应的所述第二显示面板的亮度进行校正，得到所述至少一个绑点灰阶对应的经过第二次校正的第二显示面板的亮度。即，所述第二显示面板的第二校正亮度可以与所述至少一个绑点灰阶相对应，并经过第二次校正进行调整。
步骤S50：根据所述第一校正亮度以及所述第二校正亮度对所述第二显示面板的亮度进行第三次校正，得到所述第二显示面板的第三校正亮度，以使所述第二显示面板的亮度与所述第一显示面板的亮度相匹配。
其中，根据所述第一校正亮度以及所述第二校正亮度对所述第二显示面板的亮度进行第三次校正，得到所述第二显示面板的第三校正亮度，包括：
步骤S501：根据所述第一校正亮度以及所述第二校正亮度生成与所述至少一个绑点灰阶对应的第一增益系数；
步骤S502：基于所述至少一个绑点灰阶对应的第一增益系数进行线性插值，得到对应于所述第二显示面板的各级亮度的第二增益系数；
步骤S503：根据所述第二增益系数对所述第二显示面板的亮度进行第三次校正，得到所述第二显示面板的第三校正亮度。
进一步地，根据所述第一校正亮度以及所述第二校正亮度生成与所述至少一个绑点灰阶对应的第一增益系数。例如，在所述绑点灰阶为7个的情况下，将经过第二次校正后的所述第二校正亮度与经过第一次校正后的所述第一校正亮度作比值，可以得到对应于7个绑点灰阶的7个第一增益系数。
进一步地，基于所述至少一个绑点灰阶对应的增益系数进行线性插值，得到对应于所述第二显示面板的各级亮度的第二增益系数。其中，所述第二显示面板的亮度可以用16位来表示，即所述第二显示面板的亮度可以分为0至65535个亮度等级。所述第二显示面板的灰阶可以与所述第二显示面板的亮度相对应。例如，在本申请实施例中，选取7个绑点灰阶，对在7个绑点灰阶下所述第二显示面板的亮度进行校正后，可以通过一维线性插值基于所述至少一个绑点灰阶对应的第一增益系数得到对应于0至65535个亮度下的各个亮度，即通过线性插值将8位灰阶对应的亮度扩充到16位的亮度等级，从而得到对应于65536个等级亮度的第二增益系数。
进一步地，根据所述第二增益系数对所述第二显示面板的亮度进行第三次校正，得到所述第二显示面板的第三校正亮度。例如，所述第二增益系数设置有65536个，即对于所述第二显示面板的每个亮度等级都可以得到对应的第二增益系数，并可以将此第二增益系数与所述第二显示面板的第一校正亮度进行运算（例如，相乘），从而得到所述第二显示面板的第三校正亮度。
通过根据所述第一校正亮度以及所述第二校正亮度生成与所述至少一个绑点灰阶对应的第一增益系数，并基于所述第一增益系数进行线性插值，进而对所述第二显示面板的亮度进行第三次校正，本申请实施例能够将对于选定的绑点灰阶的校正扩充到所述第二显示面板的全部灰阶，减少了校正过程中的计算量，提高了所述第二显示面板的亮度校正的准确性。
进一步地，所述显示器的显示画面包括多个颜色，所述第一校正亮度、所述第二校正亮度以及所述第三亮度分别与所述显示器的显示画面的各个颜色相对应。例如，所述多个颜色可以是红（即，R）、绿（即，G）、蓝（即，B）。因此，在本申请实施例中，可以按照上述方法遍历对应于各个颜色下的对应的灰阶，对所述第二显示面板的亮度进行调节，得到对应于各个颜色的第二显示面板的亮度表。最终将该亮度表导入给显示面板中的控制系统（例如时序控制器），从而使第二显示面板的亮度与第一显示面板的亮度达到一致，保证第二显示面板的显示效果与第一显示面板的显示效果的一致性。
通过对所述显示面板的各个颜色进行遍历，本申请实施例能够保证校正过程的完整性，扩大了校正过程的应用范围，进一步提高所述第二显示面板的亮度校正的准确性。
