【背景技术】
显示面板发展越来越多元化，人们对手机的需求越来越苛刻。为了能满足大众的需求，面板厂商也对面板的设计做出各种调整，比如改变设计降低面板的功耗，改变其色阻材料提高面板的显示效果等等。在对面板功耗降低的设计上，可以通过减小GOA（Gate Driver on Array，阵列基板驱动）的驱动TFT（Thin Film Transistor，薄膜晶体管）及改变像素的设计，随着而产生的就有WRGB面板设计，选用WRGB像素设计能降低面板的功耗，从而能降低面板在手机、电脑等电器上面的功耗。然而WRGB像素设计的面板，在显示纯色，或者是彩色画面时，与RGB显示面板相比，在同样的背景显示画面下，其纯色亮度就会越低，画面显示就会失真，严重影响画面的光学品质。

为解决上述技术问题，本发明采用的另一个技术方案是：提供一种像素结构，该像素结构至少包括相邻设置的第一像素电极和第二像素电极，第一像素电极包括第一有效显示部和第一非有效显示部，第二像素电极包括第二有效显示部和第二非有效显示部，第一有效显示部的显示面积小于第二有效显示部的显示面积，第二像素电极的实际覆盖面积与第一像素电极的实际覆盖面积的比值范围为1~2/3。
为解决上述技术问题，本发明采用的又一个技术方案是：提供一种显示面板包括第一基板和第二基板、夹持在第一基板和第二基板之间的液晶层、设置在第一基板上的像素结构、设置在第一基板上且与像素结构在液晶显示面板的厚度方向间隔设置的公共电极层，像素结构至少包括相邻设置的第一像素电极和第二像素电极，第一像素电极包括第一有效显示部和第一非有效显示部，第二像素电极包括第二有效显示部和第二非有效显示部，第一有效显示部的显示面积小于第二有效显示部的显示面积，第二像素电极的实际覆盖面积与第一像素电极的实际覆盖面积的比值范围为1~2/3。
本发明的有益效果是：区别于现有技术的情况，本发明通过第一有效显示部的显示面积小于第二有效显示部的显示面积，可以通过增加第二像素电极的显示所占比例，降低面板彩色画面的失真度，提升彩色画面的光学品味，第二像素电极的实际覆盖面积与第一像素电极的实际覆盖面积的比值范围为1~2/3，能够使得第一像素电极对应的存储电容和第二像素电极对应的存储电容差值很小，避免产生漏电、串扰、闪烁等现象，增加显示面板的稳定性。

第二引脚部122可用于连接至对应薄膜晶体管的漏极或者源极。
第一线栅a1、a2、a3、a4的条数可以等于第二线栅b1、b2、b3、b4的条数。各个第一线栅a1、a2、a3、a4的长度可以彼此相等，各个第二线栅b1、b2、b3、b4的长度可以彼此相等。各个第一线栅a1、a2、a3、a4的宽度可以彼此相等，各个第二线栅b1、b2、b3、b4的宽度可以彼此相等。第一线栅a1、a2、a3、a4的宽度可以等于第二线栅b1、b2、b3、b4的宽度。第一线栅a1、a2、a3、a4的长度可以大于第二线栅b1、b2、b3、b4的长度。
本实施例通过设置第一有效显示部111的显示面积小于第二有效显示部121的显示面积，可以通过增加第二像素电极12（红色像素电极、蓝色像素电极或者绿色像素电极）的显示所占比例，降低面板彩色画面的失真度，提升彩色画面的光学品味，在此基础上，通过增加第一延伸部a和第二延伸部b，增加第一引脚部1123的面积，使得第一非有效显示部112的面积大于第二非有效显示部122的面积，从而减小第二像素电极12的实际覆盖面积与第一像素电极11的实际覆盖面积的差值，进而使得第一像素电极对应的存储电容与第二像素电极对应的存储电容的差值减小，避免产生漏电、串扰、闪烁等现象，增加显示面板的稳定性。
请参阅图2，图2是本发明另一种实施例的像素结构的结构示意图。在本实施例中，像素结构20可至少包括相邻设置的第一像素电极21和第二像素电极22。
例如，第一像素电极21可以为白色像素电极，第二像素电极22可以为红色像素电极、蓝色像素电极或者绿色像素电极。
第一像素电极21可包括第一有效显示部211和第一非有效显示部212。
第二像素电极22可包括第二有效显示部221和第二非有效显示部222。
第一非有效显示部212可为第一像素电极21被黑色矩阵23遮盖的部分，第一有效显示部211可为第一像素电极21未被黑色矩阵23遮盖的部分。第二非有效显示部222可为第二像素电极22被黑色矩阵23遮盖的部分，第二有效显示部221可为第二像素电极22未被黑色矩阵23遮盖的部分。
第一有效显示部211的显示面积小于第二有效显示部221的显示面积。
第二像素电极22的实际覆盖面积与第一像素电极21的实际覆盖面积的比值范围为1~2/3。
在一种实施例中，第二像素电极22的实际覆盖面积与第一像素电极21的实际覆盖面积的差值范围为0，即第二像素电极22的实际覆盖面积与第一像素电极21的实际覆盖面积相等。
第一有效显示部211可包括多条间隔设置的第一线栅c1、c2、c3，第二有效显示部221可包括多条间隔设置的第二线栅d1、d2、d3、d4，第一线栅c1、c2、c3的条数少于第二线栅d1、d2、d3、d4的条数，各个第一线栅c1、c2、c3的宽度可以彼此相等，各个第二线栅d1、d2、d3、d4的宽度可以彼此相等，第一线栅c1、c2、c3的宽度大于第二线栅d1、d2、d3、d4的宽度。
进一步，第一非有效显示部212的面积可大于第二非有效显示部222的面积。具体如何将第一非有效显示部212的面积设置为大于第二非有效显示部222的面积，请看前文的描述，此处不再赘述。在其他实施例中，第一非有效显示部212的面积也可以小于或者等于第二非有效显示部222的面积，而只是通过改变第一线栅c1、c2、c3和第二线栅d1、d2、d3、d4的条数关系和宽度关系来使第二像素电极22的实际覆盖面积与第一像素电极21的实际覆盖面积的比值范围为1~2/3。
本实施例通过设置第一有效显示部211的显示面积小于第二有效显示部221的显示面积，可以通过增加第二像素电极22（红色像素电极、蓝色像素电极或者绿色像素电极）的显示所占比例，降低面板彩色画面的失真度，提升彩色画面的光学品味，在此基础上，通过设置第一线栅c1、c2、c3的条数少于第二线栅d1、d2、d3、d4的条数，第一线栅c1、c2、c3的宽度大于第二线栅d1、d2、d3、d4的宽度，从而减小第二像素电极12的实际覆盖面积与第一像素电极11的实际覆盖面积的差值，进而使得第一像素电极11对应的存储电容与第二像素电极12对应的存储电容的差值减小，避免产生漏电、串扰、闪烁等现象，增加显示面板的稳定性。
请参阅图3，图3是本发明实施例的显示面板结构示意图。在本实施例中，显示面板可包括：第一基板31和第二基板32、夹持在第一基板31和第二基板32之间的液晶层33、设置在第一基板31上的像素结构34、设置在第一基板31上且与像素结构34在液晶显示面板的厚度方向间隔设置的公共电极层35。
像素结构34为上述任意一实施例中所述的像素结构，此处不再赘述。图3中仅示出像素结构的一个像素电极，例如第一像素电极或者第二像素电极，但本领域技术人员不难理解其相邻的像素电极与之构成前述实施中的像素结构。
在一种实施方式中，显示面板还可以包括设置于第一基板31上的遮光层36、设置在遮光层36和第一基板31上的缓冲层37、设置在缓冲层37上的多晶硅半导体层38、设置在多晶硅半导体层38上的栅极绝缘39、设置在栅极绝缘层39上的栅极层40、栅极在栅极层40上的层间绝缘层41、设置在层间绝缘层41上的漏源层42、设置在漏源层42上的平坦化层43、设置在平坦化层43上的公共电极层35、设置在公共电极层35上的钝化层44、设置在钝化层44上的像素结构34。像素结构34在公共电极层35上的投影被公共电极层35覆盖。栅极层40和漏源层42形成薄膜晶体管结构。
像素结构37为像素电极层，像素电极层通过过孔与漏源层42电连接。
在一种实施例中，显示面板还可以包括设置于第二基板32上的黑色矩阵和彩色滤光片。
以上仅为一种显示面板的示例，显示面板可以采用其他显示原理的显示面板本发明实施例对此不做限定，显示面板还可以包括其他的膜层或者其他元件，此处不一一列举。
在显示面板工作时，像素结构的第一像素电极和公共电极层之间会产生第一存储电容，像素结构的第二像素电极和公共电极层之间会产生第二存储电容，由于第二像素电极的实际覆盖面积与第一像素电极的实际覆盖面积的比值范围为1~2/3，能够第一存储电容和第二存储电容差值很小，不会产生漏电、串扰、闪烁等现象，增加显示面板的稳定性。
本发明实施例通过设置第一有效显示部的显示面积小于第二有效显示部的显示面积，可以通过增加第二像素电极的显示所占比例，降低面板彩色画面的失真度，提升彩色画面的光学品味，通过设置第二像素电极的实际覆盖面积与第一像素电极的实际覆盖面积的比值范围为1~2/3，能够使得第一像素电极对应的存储电容和第二像素电极对应的存储电容差值很小，不会产生漏电、串扰、闪烁等现象，增加显示面板的稳定性。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
