本申请实施例提供了一种液晶显示面板，包括彩膜基板、与所述彩膜基板相对设置的阵列基板、和位于所述彩膜基板与所述阵列基板之间的液晶层，所述彩膜基板包括红（R）、绿（G）、蓝（B）、白（W）四种色阻，所述阵列基板上与所述白色阻相对应的区域设置有加热层，所述加热层可以对所述液晶层进行加热，防止所述液晶显示面板在低温环境下工作时出现动态拖影和显示异常。
下面参照附图具体说明本申请实施例提供的液晶显示面板的结构和工作原理：
如图1所示，为本申请实施例提供的液晶显示面板的结构示意图，所述液晶显示面板包括彩膜基板11、与所述彩膜基板11相对设置的阵列基板12、以及设置于所述彩膜基板11与所述阵列基板12之间的液晶层13。
如图2所示，所述彩膜基板11包括红R、绿G、蓝B、白W四种色阻，所述四种色阻在所述彩膜基板11上阵列排布。可选地，所述四种色阻在所述彩膜基板11上可以按照图2所示的矩形阵列排布；可选地，所述四种色阻在所述彩膜基板11上也可以横向或竖向排布，即所述彩膜基板11的每一行色阻可以按照红、绿、蓝、白顺序排布，也可以是每一列色阻按照红、绿、蓝、白顺序排布。本申请对所述四种色阻的排列方式不做限制。
需要说明的是，所述四种色阻的彼此交界处通过黑色矩阵111隔开，以防止所述四种色阻的彼此交界处受双色阻的影响出现的显示异常。
如图3所示，所述阵列基板12包括垂直排列的多条数据线D和多条栅极线S，所述数据线D和所述栅极线S在位置关系上与所述彩膜基板11上黑色矩阵111（参考图2所示）相对应，所述黑色矩阵111可以对所述数据线D和所述栅极线S的走线区进行遮挡，防止所述数据线D和所述栅极线S显露于外部。所述数据线D和所述栅极线S将所述阵列基板12划分为多个子像素区，每个所述子像素区分别对应所述彩膜基板11（参考图2所示）上的红、绿、蓝、白四种色阻中的一种色阻，其中，与所述红色阻R相对应的所述子像素区定义为第一子像素区R1，与所述绿色阻G相对应的所述子像素区定义为第二子像素区G1，与所述蓝色阻B相对应的所述子像素区定义为第三子像素区B1，与所述白色阻W相对应的所述子像素区定义为第四子像素区W1。所述第四子像素区W1内设置加热层12a，用于对所述液晶层13（参考图1所示）进行加热，防止所述液晶层13中的液晶在低温环境下出现晶态异常，进而引发液晶显示面板的显示异常。
需要说明的是，所述加热层12a与加热控制模块连接，所述加热控制模块可以设置于所述液晶显示面板的非显示区，当所述液晶显示面板处于低温环境下工作时，所述加热控制模块控制所述加热层12a发热，对所述液晶层13进行加热，保证所述液晶显示面板的正常工作。
应当理解的是，在包含红、绿、蓝、白四色色阻的液晶显示面板中，白色阻在液晶显示面板的显示区域均匀分布，本申请将加热层设置于与所述白色阻相对应的区域，可以实现对液晶层的均匀加热，且加热面积大，加热效率高。
需要说明的是，设置有加热层的所述白色阻区域为不发光区域，所述显示面板的显示画面可以通过所述红、绿、蓝三色色阻发出的红、绿、蓝三色光的混色实现。因此，本申请将所述加热层设置于与所述白色阻相对应的区域不会对所述液晶显示面板显示画面的功能产生影响。
根据本申请一实施例，如图4所示，所述阵列基板12包括基板121、设置于所述基板121之上的走线层122、设置于所述走线层122之上的第一钝化层123、设置于所述第一钝化层123之上的第一电极层124、设置于所述第一电极层124之上的第二钝化层125、以及设置于所述第二钝化层125之上的第二电极层126。所述第一电极层124用于提供第一电场，所述第二电极层126用于提供第二电场，所述液晶层13（参考图1所示）中的液晶在所述第一电场和所述第二电场的作用下发生偏转，从而使所述液晶显示面板显示不同的画面。
可选地，所述加热层12a设置于所述第一电极层124的下方，所述第一电极层124可以对所述加热层12a的电场起到屏蔽作用，防止所述加热层12a的电场影响所述液晶层13（参考图1所示）。优选地，所述加热层12a设置于所述第一钝化层123与所述走线层122之间，所述第一钝化层123将所述加热层12a与所述第一电极层124隔开，使所述第一电极层124对所述加热层12a的电场起到更好的屏蔽作用。
可选地，所述走线层122包括所述栅极线S、所述数据线D（参考图3所示）以及与所述栅极线S和所述数据线D连接的薄膜晶体管。所述栅极线S、所述数据线D、所述薄膜晶体管与所述加热层12a绝缘隔开。
根据本申请一实施例，如图5所示，所述阵列基板12还包括第一加热走线12b和第二加热走线12c。所述第一加热走线12b与所述栅极线S平行设置，且所述第一加热走线12b的宽度小于或等于所述栅极线走线区S’的宽度，从而保证所述第一加热走线12b不会对液晶显示面板的开口率产生影响。所述第二加热走线12c与所述数据线D平行设置，且所述第二加热走线12c的宽度小于或等于所述数据线走线区D’的宽度，从而保证所述第二加热走线12c不会对液晶显示面板的开口率产生影响。
需要说明的是，所述栅极线走线区S’是所述栅极线S的布线区域，所述数据线走线区D’是所述数据线D的布线区域，所述栅极线走线区S’和所述数据线走线区D’与所述黑色矩阵111（参考图2所示）相对应。所述黑色矩阵111对所述栅极线走线区S’和所述数据线走线区D’进行遮挡，可以防止所述栅极线S、所述数据线D及所述第一加热走线12b和所述第二加热走线12c显露于外部。
本申请实施例提供的阵列基板，在原有的发热层的基础上，又增加了第一加热走线和第二加热走线，使所述阵列基板上的加热区域的面积增加，且加热区域的分布更加均匀，对液晶层有更好的加热效果。
根据本申请一实施例，如图5所示，所述加热层12a完全覆盖所述第四子像素区W1，以达到最优的加热效果。所述第四子像素区W1为不透光区域，所述第四子像素区W1对所述液晶显示面板的显示画面不发挥作用，所述液晶显示面板的显示画面通过所述第一子像素区R1、第二子像素区G1和所述第三子像素区B1实现。应当理解的是，通过调节液晶显示面板的红、绿、蓝三色像素，可以实现液晶显示面板的全彩显示，因此，本申请将所述第四子像素区W1设置为不发光区域不会影响所述液晶显示面板的显示功能。
应当理解的是，所述液晶显示板包括显示区和位于显示区边缘的非显示区，显示区用于显示画面，非显示区用于设置不具有显示功能的元件，如各种电路控制元件等。
可选地，所述第一加热走线12b贯穿所述液晶显示面板的显示区，并连接至所述液晶显示面板非显示区上的加热控制模块14，所述加热控制模块14控制所述第一加热走线12b的加热功能。
可选地，所述第二加热走线12c沿所述加热层12a的边缘设置，且连接于相邻两条所述第一加热走线12b之间，所述第二加热走线12c与所述加热层12a及所述第一加热走线12b保持连接。所述加热控制模块14通过所述第一加热走线12b控制所述第二加热走线12c及所述加热层12a的加热功能。
根据本申请一实施例，如图6所示，所述加热层12a部分覆盖所述第四子像素区W1。所述第四子像素区W1被所述加热层12a覆盖的区域为不透光区域；所述第四子像素区W1未被所述加热层12a覆盖的区域为正常透光区，所述正常透光区可以为所述液晶显示面板的显示画面提供白光，提升所述液晶显示面板的显示亮度。应当理解的是，虽然所述第四子像素区W1中的部分区域为不透光区，但不会影响所述液晶显示面板显示画面的功能，所述液晶显示面板可以通过调节红、绿、蓝三色像素实现全彩显示。
可选地，所述第一加热走线12b贯穿所述液晶显示面板的显示区，并连接至所述液晶显示面板非显示区上的加热控制模块14，所述加热控制模块14控制所述第一加热走线12b的加热功能。
可选地，所述第二加热走线12c沿所述加热层12a的边缘设置，且与所述加热层12a连接。所述第二加热走线12c至少一端与所述第一加热走线12b连接。所述加热控制模块14通过所述第一加热走线12b控制所述加热层12a和所述第二加热走线12c的加热功能。
可选地，所述加热层12a、所述第一加热走线12b和所述第二加热走线12c朝向所述液晶层13（参考图1所示）的一面为黑色，以降低所述加热层12a、所述第一加热走线12b及所述第二加热走线12c对光线的反射作用。可选地，所述黑色矩阵111（参考图2所示）完全遮挡所述加热层12a、所述第一加热走线12b和所述第二加热走线12c，以防止所述加热层12a、所述第一加热走线12b及所述第二加热走线12c显露于外部。
根据本申请一实施例，如图1和图5所示，所述液晶显示面板还包括温度传感器15，用于探测所述液晶层13的温度。所述温度传感器15与所述加热控制模块14连接。
所述加热控制模块14控制加热模块对所述液晶层13进行加热的流程如图8所示，需要说明的是，图8中所示的加热模块12a/b/c包括加热层12a、第一加热走线12b和第二加热走线12c（参考图5所示）。如图8所示，所述温度传感器15探测所述液晶层13的温度，并将得到的温度数据传递给所述加热控制模块14，所述加热控制模块14对所述温度数据进行判断，并进一步控制开启或关闭所述加热模块12a/b/c，进而所述加热模块12a/b/c对所述液晶层13执行或不执行加热操作。
具体地，所述加热控制模块14对所述温度数据进行判断的方法是：设定一温度阈值，所述加热控制模块14判断所述温度数据与所述温度阈值的大小关系。若所述温度数据小于或等于所述温度阈值，则开启所述加热模块12a/b/c；若所述温度数据大于所述温度阈值，则关闭所述加热模块12a/b/c。可选地，所述温度阈值可以是液晶的结晶温度值或大于液晶结晶温度值的某个值。可选地，所述温度阈值可以是分段设置的温度范围，所述加热控制模块14根据所述温度数据与所述温度范围的关系控制所述加热模块12a/b/c的加热功率，例如，液晶的结晶温度为T1，设置T0~T1为第一温度阈值，T1~T2为第二温度阈值，大于T2为第三温度阈值，其中T0 < T1 < T2，所述温度数据处于所述第一温度阈值内时所述加热模块12a/b/c的加热功率大于所述温度数据处于所述第二温度阈值内时所述加热模块12a/b/c的加热功率，所述温度数据处于所述第三温度阈值内时，所述加热模块12a/b/c停止加热。本实施例提供的液晶层加热方案可以实现对所述液晶层温度的实时监控。
