请参照图1，图1为本发明第一实施例的图像显示方法的流程图。
如图1所示，本实施例的图像显示方法包括以下步骤：
S101、输入初始图像数据；
在显示面板上显示时，所述初始图像数据通过共享像素的方式显示；即所述初始图像数据能够在具有特殊像素排列方式的显示面板上显示（譬如Pentile显示面板），这种面板在实际显示图像时，其中一个像素会共享与其相邻像素中的一种子像素来构成基本的像素，每个基本的像素包括红色子像素、蓝色子像素、绿色子像素，譬如其中一个像素缺少蓝色子像素，而该像素会共用与其相邻的像素中的蓝色子像素。
S102、将所述初始图像数据转换得到处理图像数据；
在所述显示面板上显示时，所述处理图像数据进行独立像素显示；所述处理图像数据在显示过程中不存在像素共享的现象。将所述初始图像数据按照预设的映射关系转换为处理图像数据，在制作Pentile显示面板时，就确定了这种映射关系。不同的Pentile显示面板，映射关系也不同。
S103、根据灰阶补偿列表，对所述处理图像数据中的像素数据进行灰阶数据补偿；
在进行S103步骤之前，已经得到了所述灰阶补偿列表。请参照图2，S103步骤中的灰阶补偿列表，通过以下步骤生成具体包括：
S201、获取测试图像数据的像素数据在多个不同预设灰阶下的测试灰阶数据；
测试图像数据可由显示面板的内部图像发生器提供，所述测试图像数据可以在所述显示面板上进行独立像素显示，即不存在像素共享的现象。预设灰阶也就是目标灰阶，譬如显示面板的灰阶阈值为0-255，所述预设灰阶譬如为100、200、254。所述测试图像数据在预设灰阶为100、200、254时，分别将具有上述灰阶值的测试图像数据在显示面板上显示，获取所述测试图像数据的像素数据在这几个灰阶值下具有的灰阶数据（即测试灰阶数据）。
S202、根据所述测试灰阶数据和预设灰阶数据，获取灰阶补偿列表。
将S201步骤中获取的测试灰阶数据和预设灰阶数据通过预设函数关系，获取灰阶补偿列表。譬如将测试图像的像素数据在预设灰阶值为100时的测试灰阶数据和预设灰阶数据通过预设函数关系的运算，得到该预设灰阶下所述灰阶补偿列表。所述灰阶补偿列表可包括多组。每个所述灰阶补偿列表譬如是由测试灰阶数据、预设灰阶数据以及灰阶补偿值组成的列表。
S104、将所述灰阶数据补偿后的所述处理图像数据在所述显示面板进行显示操作；
可以将经过灰阶数据补偿后的所述处理图像数据直接进行显示，也可以将经过灰阶数据补偿后的所述处理图像数据，转换为可以在具有特殊像素排列方式的显示面板上显示的图像。
通过上述过程，将在pentile显示面板上显示的具有像素共享的图像数据进行转换，使pentile显示面板上的图像数据不再存在像素共享，从而在出现显示不均时，能够确定具体是由哪个像素引起的。再对不存在像素共享的图像数据的像素数据的灰阶数据进行灰阶补偿，从而解决了现有技术不能够对pentile显示面板出现的显示不均进行处理的问题，提高了显示面板的显示效果，上述方法同样适用于液晶显示器（LCD，Liquid Crystal Display）和有机发光二极管显示器（OLED，Organic Light-Emitting Diode）。
本发明的图像显示方法，通过提供一种改进的方法，解决了特殊像素排列方式面板出现的显示不均的问题，从而提高显示效果。
请参照图3，图3为本发明第二实施例的图像显示方法的流程图。
如图3所示，本实施例的图像显示方法包括以下步骤：
S301、输入初始图像数据；
在显示面板上显示时，所述初始图像数据通过共享像素的方式显示；即所述初始图像数据能够在具有特殊像素排列方式的显示面板上显示（譬如Pentile显示面板），这种面板在实际显示图像时，其中一个像素会共享与其相邻的像素的一种子像素来构成基本的像素，每个基本的像素包括红色子像素、蓝色子像素、绿色子像素，譬如其中一个像素缺少蓝色子像素，而该像素会共用与其相邻的像素中的蓝色子像素。
S302、将所述初始图像数据转换得到处理图像数据；
在所述显示面板上显示时，所述处理图像数据能够进行独立像素显示；即所述处理图像数据在显示过程中不存在像素共享的现象。将所述初始图像数据按照预设映射关系转换为处理图像数据，在制作Pentile显示面板时，就确定了预设映射关系。不同的Pentile显示面板，预设映射关系也不同。
S303、获取所述处理图像数据中的像素数据的第一灰阶数据；
所述处理图像数据包括像素数据，在S302步骤之后，获取所述处理图像数据中的像素数据的灰阶数据（将其称为第一灰阶数据）。
S304、所述第一灰阶数据和灰阶补偿列表通过预设规则，获取所述第一灰阶数据对应的灰阶补偿值；
在S303步骤之后，由于在显示面板出厂前，已经得到了灰阶补偿列表，显示面板不同，灰阶补偿列表也不同。所述第一灰阶数据和灰阶补偿列表之间的函数关系（预设规则）也是提前设定好的，因此所述第一灰阶数据和灰阶补偿列表按照预设规则得到所述第一灰阶数据对应的灰阶补偿值。所述预设规则譬如为查找、逻辑运算等方式。譬如所述第一灰阶数据在所述灰阶补偿列表查找后，得到所述第一灰阶数据对应的灰阶补偿值。或者将所述第一灰阶数据与所述灰阶补偿列表中的预设灰阶数据进行逻辑运算后，得到所述第一灰阶数据对应的灰阶补偿值。所述灰阶补偿列表譬如包括第一灰阶数据、以及对应于第一灰阶数据的灰阶补偿值。
S305、将所述第一灰阶数据对应的灰阶补偿值进行存储。
在S304获取所述第一灰阶数据对应的灰阶补偿值的步骤之后，对所述第一灰阶数据对应的灰阶补偿值进行存储，以便于当显示面板输入相同灰阶值的图像数据时，直接使用存储的灰阶补偿值对其进行补偿，节省了显示面板的响应时间。
S305、根据所述灰阶补偿值对所述处理图像数据中的像素数据的第一灰阶数据进行补偿。
在S304步骤获取到所述第一灰阶数据对应的灰阶补偿值之后，使用所述灰阶补偿值对所述处理图像数据中的像素数据的第一灰阶数据进行补偿，从而消除了显示面板的显示不均的现象。
请结合图2，S304步骤中的灰阶补偿列表，通过以下步骤生成具体包括：
S201、获取测试图像数据的像素数据在多个不同预设灰阶下的测试灰阶数据；
测试图像数据可由显示面板的内部图像发生器提供，所述测试图像数据可以在所述显示面板上进行独立像素显示，即不存在像素共享的现象。预设灰阶也就是目标灰阶，譬如显示面板的灰阶阈值为0-255，所述预设灰阶譬如为100、200、254。所述测试图像数据在预设灰阶为100、200、254时，分别将具有上述灰阶值的测试图像数据在显示面板上显示，获取所述测试图像数据的像素数据在这几个灰阶值下具有的灰阶数据（即测试灰阶数据）。
优选地，S201步骤可以通过以下方式实现：
S2011、分别获取测试图像数据的每个像素数据在同一预设灰阶下的测试灰阶数据；
测试图像数据的像素数据的种类包括红色、绿色、蓝色，还可包括白色、黄色等；设置多个不同预设灰阶，获取测试图像数据中的每种像素数据在每个预设灰阶下的测试灰阶数据，譬如在获取所述测试图像数据的像素数据在灰阶值为100时的测试灰阶数据，分别获取蓝色像素数据在灰阶值为100时的测试灰阶数据、红色像素数据在灰阶值为100时的测试灰阶数据、绿色像素数据在灰阶值为100时的测试灰阶数据。
通过分别获取每种像素数据的测试灰阶数据，当测试图像数据较大时，针对每一种像素数据制作灰阶补偿列表，从而避免了得到的灰阶补偿列表较大，增加了运算的复杂度，有利于节省存储空间。
S202、根据所述测试灰阶数据和预设灰阶数据，获取灰阶补偿列表。
将S201步骤中获取的测试灰阶数据和预设灰阶数据通过预设函数关系，获取灰阶补偿列表。譬如将测试图像的像素数据在预设灰阶为100时的测试灰阶数据和预设灰阶数据通过预设函数关系的运算，获取该预设灰阶下的所述灰阶补偿列表。所述灰阶补偿列表譬如是由测试灰阶数据、预设灰阶数据以及灰阶补偿值组成的列表。
S104、将所述灰阶数据补偿后的所述处理图像数据在所述显示面板进行显示操作；
可以将经过灰阶数据补偿后的所述处理图像数据直接进行显示，也可以将经过灰阶数据补偿后的所述处理图像数据，转换为可以在具有特殊像素排列方式的显示面板上显示的图像。
所述显示面板的像素包括红色子像素、绿色子像素、蓝色子像素、白色子像素。通过上述过程，将在pentile显示面板上显示的具有像素共享的图像数据进行转换，使pentile显示面板上的图像数据不再存在像素共享，从而在出现显示不均时，能够确定具体是由哪个像素引起的。再对不存在像素共享的图像数据的像素数据的灰阶数据进行灰阶补偿，从而解决了现有技术不能够对pentile显示面板出现的显示不均进行处理的问题，提高了显示面板的显示效果，上述方法同样适用于液晶显示器（LCD，Liquid Crystal Display）和有机发光二极管显示器（OLED，Organic Light-Emitting Diode）。

所述显示模块24将所述补偿模块23进行灰阶数据补偿后的处理图像数据在所述显示面板进行显示操作。
所述显示模块24可以将经过灰阶数据补偿后的所述处理图像数据直接进行显示，也可以将经过灰阶数据补偿后的所述处理图像数据，转换为可以在具有特殊像素排列方式的显示面板上显示的图像。
所述显示面板的像素包括红色子像素、绿色子像素、蓝色子像素、白色子像素。通过上述过程，将在pentile显示面板上显示的具有像素共享的图像数据进行转换，使pentile显示面板上的图像数据不再存在像素共享，从而在出现显示不均时，能够确定具体是由哪个像素引起的。再对不存在像素共享的图像数据的像素数据的灰阶数据进行灰阶补偿，从而解决了现有技术不能够对pentile显示面板出现的显示不均进行处理的问题，提高了显示面板的显示效果，上述方法同样适用于液晶显示器（LCD，Liquid Crystal Display）和有机发光二极管显示器（OLED，Organic Light-Emitting Diode）。
本发明的图像显示方法，通过提供一种改进的装置，解决了特殊像素排列方式面板出现的显示不均的问题，从而提高显示效果。
本发明还提供一种显示器件，所述显示器件可包括上述任何一种图像显示装置，鉴于图像显示装置在上文已有描述，在此不再赘述。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
