但是由于在施加电压过程中,仅在一个连接区域接入施加电压的电压源,其他连接区域通过线路与该电压源连接。因此离电压源距离越远的连接区域的彩膜基板上输入的电压损耗越大,使得液晶显示器在显示过程中出现暗纹、色偏等不良现象,从而影响液晶显示器的显示效果。
故,有必要提供一种液晶显示面板的制作方法,以解决现有技术所存在的问题。

为让本发明的上述内容能更明显易懂,下文特举优选实施例,并配合所附图式,作详细说明如下:
附图说明
图1为现有的液晶显示面板的结构示意图;
图2为现有技术的输入到各连接区域的交流偏转电压的波形图;
图3为本发明的液晶显示面板的结构示意图;
图4为本发明的液晶显示面板的制作方法流程图;
图5为本发明的输入到各连接区域的交流偏转电压的波形图。
具体实施方式
以下各实施例的说明是参考附加的图式,用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语,例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等,仅是参考附加图式的方向。因此,使用的方向用语是用以说明及理解本发明,而非用以限制本发明。
在图中,结构相似的单元是以相同标号表示。
请参照图1,图1为现有技术的液晶显示面板的结构示意图。
现有的所述液晶显示面板包括阵列基板10、彩膜基板11以及设置在所述阵列基板10和所述彩膜基板11之间的液晶层,其中所述阵列基板10的内表面和所述彩膜基板11的内表面设置有用于保持所述液晶层中的液晶分子15的预倾角的聚合物配向膜14;现有的液晶显示面板的制作方法包括:
制成由所述阵列基板10和所述彩膜基板11构成的液晶盒,所述液晶盒中注入含有聚合物单体的液晶分子;
在所述阵列基板10的透明电极12以及所述彩膜基板11的透明电极13之间施加交流偏转电压,以使得所述液晶分子15形成预倾角;以及
对所述液晶显示面板进行紫外线照射,使所述聚合物单体合成聚合物,以在所述阵列基板10的内表面和所述彩膜基板11的内表面形成聚合物配向膜14。
将所述彩膜基板11的透明电极13划分为多个连接区域101-104。
通常仅在所述液晶显示面板的阵列基板10上设置有交流电压源,譬如通过金球将阵列基板10上的交流电压源电源传递至所述彩膜基板11上,且所述交流电压源的输出点通常在所述彩膜基板11上的一个连接区域(譬如101),其他连接区域102-104的金球通过连接线路与连接区域101上的输入交流电压源实现电连接,由于距离输入交流电压源越远,线路设置的越长,导致输入交流电压源在极性变化时,距离输入交流电压源越远的连接区域的输入的交流电压损耗越大。如图2所示,在同一时间(t1)输入电压值大小相同的交流电压源时,所述连接区域101的电压的输出波形为C1,所述连接区域102的电压的输入波形为C2、所述连接区域103的电压的输入波形为C3、所述连接区域104的电压的输入波形为C4,从图2可以看出,C2,C3,C4的电压缓慢地上升到输入电压的电压值,在时间为t2时,所述连接区域输入交流电压的电压值均相等。因此越远离输入电压源的连接区域(连接区域101),其对应的输入交流电压损耗越大,从而导致每个连接区域的液晶分子的偏转角度不一致。
请参照图3,图3为本发明的液晶显示面板的结构示意图。
结合图3,本发明的所述液晶显示面板包括阵列基板20、彩膜基板21以及设置在所述阵列基板20和所述彩膜基板21之间的液晶层,其中所述阵列基板20的内表面和所述彩膜基板21的内表面设置有用于保持所述液晶层中的液晶分子的预倾角的聚合物配向膜24。
为了具有更好的显示效果,将所述彩膜基板21的透明电极23划分为多个连接区域201-204。
在每个所述连接区域和所述阵列基板的透明电极22之间都设置一金球,且所述交流电压源的输出点通常在所述彩膜基板21上的一个连接区域(譬如201),其他连接区域202-204的金球通过连接线路与连接区域201上的输入交流电压源实现电连接,
如图4所示,本发明的液晶显示面板的制作方法包括:
S201、制成由所述阵列基板和所述彩膜基板构成的液晶盒,所述液晶盒中注入含有聚合物单体的液晶分子。
其中,所述聚合物单体的材料为烯基化合物。所述液晶盒中还可注入液晶配向剂,所述液晶配向剂选自聚酰胺酸、聚酰胺酸酯、聚酰亚胺及聚有机硅氧烷的至少一种聚合物。
S202、检测所述液晶显示面板的各个连接区域的所述阵列基板的透明电极与相应的所述彩膜基板的透明电极之间的交流偏转电压。
通过在所述阵列基板20的透明电极22以及所述彩膜基板21的透明电极23之间施加交流偏转电压,以使得所述液晶分子25形成预倾角;以及
优选地,在所述阵列基板20的透明电极22上施加公共电压,在所述彩膜基板21的透明电极23上施加交流偏转电压。所述交流偏转电压譬如为交流方波信号。
S203、当所有所述交流偏转电压的电压值均等于设定值时,在所述阵列基板的透明电极以及所述彩膜基板的透明电极之间施加所述交流偏转电压。
根据S202的检测结果,确定是否在所述阵列基板的透明电极22以及所述彩膜基板的透明电极23之间施加所述交流偏转电压。所述设定值为所述交流偏转电压的输入源的电压值。
S204、对所述液晶显示面板进行紫外线照射,使所述聚合物单体合成聚合物,以在所述阵列基板20的内表面和所述彩膜基板21的内表面形成聚合物配向膜。
其中,所述步骤S203还可包括:
优选地,分别在各连接区域的所述彩膜基板21的透明电极23和所述交流偏转电压的输入源之间设置开关管,通过所述开关管,来控制是否在相应的连接区域的所述彩膜基板的透明电极23上施加交流偏转电压。
当全部连接区域201-204的所述交流偏转电压的电压值均等于设定值(所述交流偏转电压的输入源输入的电压值)时,所述开关管导通,在所述彩膜基板的透明电极23上施加交流偏转电压;当至少一个所述交流偏转电压的电压值不等于所述设定值时,所述开关管断开,在所述彩膜基板的透明电极23上不施加交流偏转电压。
当所述交流偏转电压的电压值为正时:将输入所述交流偏转电压正的幅值称为第一预设值,若所有所述交流偏转电压的电压值均等于所述第一设定值,所述开关管导通;若至少一个所述交流偏转电压的电压值不等于所述第一设定值时,所述开关管断开。
当所述交流偏转电压的电压值为负时:将输入所述交流偏转电压负的幅值称为第二预设值,若所有所述交流偏转电压的电压值均等于所述第二设定值时,所述开关管导通;若至少一个所述交流偏转电压的电压值不等于所述第二设定值时,所述开关管断开。
所述开关管的输入端连接所述交流偏转电压的输入源,所述开关管的输出端譬如通过金球连接所述彩膜基板的透明电极,所述开关管的控制端连接控制信号。
各所述连接区域的交流偏转电压的损耗均不同,所述控制信号可根据所述交流偏转电压损耗最大的连接区域的电压值产生。譬如交流偏转电压损耗最大的连接区域为204,当所述连接区域204的交流偏转电压的电压值等于所述交流偏转电压的输入源输入的电压值时,闭合所有所述连接区域的开关管。
由于每个所述开关管的输出端距离各所述连接区域的透明电极之间的连接线路的长度都相等,但是距离所述交流偏转电压的输入源之间的线路的长度不相等。因此只需要在各所述开关管输入端的电压源的电压值相等时分别闭合所有所述开关管,就可以避免每个所述连接区域的电压损耗的问题。
具体为:检测所有所述开关管输入端的所述交流偏转电压的电压值是否相等,当电压值相等时,才闭合所有所述开关管,由于在输出到各连接区域的所述彩膜基板的透明电极之前,所述交流偏转电压的输入源已经在所述开关管的输入端有输入,经过一段时间的输入后,检测各所述开关管的输入端的交流偏转电压的电压值是否都相等。
在检测电压时,可以先使各所述连接区域的开关管闭合,获取各连接区域输入的电压值达到所述设定值需要的时间(即迟延时间,譬如图2中t2-t1的差值)。此时再断开各所述连接区域的所述开关管,当输入交流偏转电压的时间达到所述迟延时间后,重新开启各所述开关管。
由于通过所述开关管的控制,前期先将所述交流偏转电压输入到所述开关管的输入端,等输入到所有所述开关管的输入端的交流偏转电压的电压值都相等时,再将所述交流偏转电压输入到各所述连接区域的透明电极上,从而很好地避免了线路长度不等造成的电压损耗问题,确保了液晶分子偏转角度保持一致。如图5所示,所述连接区域201的电压的输出波形为d1,所述连接区域202的电压的输入波形为d2、所述连接区域203的电压的输入波形为d3、所述连接区域204的电压的输入波形为d4,从图5可以看出,d1-d4的输出波形一致,不存在输入交流偏转电压损耗的问题,从而使得所述液晶显示面板的液晶分子偏转角度一致。
本发明的液晶显示面板的制作方法,通过在施加电压之前,检测彩膜基板上透明电极的输入电压的大小,当各连接区域的输入电压大小都相等时,才施加电压,能够消除显示不良的问题,,从而提高显示效果。
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。
