Description

LCD柔性液晶显示面板的制造方法
技术领域
本发明涉及一种LCD柔性液晶显示面板的制作工艺。
背景技术
传统的LCD液晶显示面板，都是基于ito导电膜玻璃基板作为主体的，玻璃基板具有刚性，所以显示面板都是平面的结构。
随着液晶显示面板的使用领域的的不断扩大，已经出现了曲面显示的液晶面板，现阶段常见的曲面液晶面板都是基于OLED的生产技术：OLED的基本结构是由一薄而透明具半导体特性之铟锡氧化物，与电力之正极相连，再加上另一个金属阴极，包成如三明治的结构。整个结构层中包括了：空穴传输层(HTL)、发光层(EL)与电子传输层(ETL)。当电力供应至适当电压时，正极空穴与阴极电荷就会在发光层中结合，产生光亮，依其配方不同产生红、绿和蓝RGB三原色，构成基本色彩。OLED的特性是自己发光，不像LCD需要背光，因此可视度和亮度均高，其次是电压需求低且省电效率高，反应快、重量轻、厚度薄，构造简单。OLED显示屏极薄、极富韧性，原本就趋于弯曲，因此用来做曲面显示屏非常合适。
由于OLED的成本较高，所以LCD现阶段还是有大量使用范围，尤其是小尺寸的笔段式显示方面。
如何在LCD液晶显示面板上，实现曲面显示效果，这是本发明需要达到的目的。
发明内容
本发明的目的是提供一种LCD柔性液晶显示面板的制造方法以弥补现有技术不足。
本发明为达到目的采用的技术方案是：LCD柔性液晶显示面板的制造方法，其特征在于：
a.选用柔性PET（聚对苯二甲酸乙二醇酯）偏光片，通过低温蒸镀将ITO（氧化铟锡）导电膜镀在PET偏光片上，形成基片；
b.再将基片上的ITO导电膜进行蚀刻，形成PET胶片，PET胶片能显示需要的图案；
c.将PI（聚酰亚胺酸）定向绝缘膜转印在带有ITO层的PET胶片上，低温固化预处理，形成PI定向层；
d.将两层PET胶片与封胶框封装成液晶盒，盒内灌注液晶，即可制得液晶显示面板。
本发明的积极效果在于：直接在PET偏光片上镀ITO膜，经蚀刻后形成图案，再覆以定向膜，这样就可以取消原有的ITO玻璃基板，PET偏光片的可弯曲性使制得的液晶显示面板为柔性，实现了曲面显示的效果，而且还减小了液晶盒的厚度，保证了弯曲形变时，叠加显示无错位差异。另外，整个过程可以利用原有的LCD制作工序流水线，是一种低成本的改进方案。
附图说明
图1为发明的结构示意图。
具体实施方式
实施例：
在图中，1为PET基片，2为PI定向层，3为封胶框，4为液晶。
选用柔性PET偏光片，透过率大于99%，且无划痕、黑点。清洗烘干，低温蒸镀将ITO导电膜镀在PET偏光片上，形成PET基片1。
将制作好的PET基片1上的ITO进行蚀刻，形成显示需要的图案。
将PI（聚酰亚胺酸）定向绝缘膜转印在带有ITO层的PET基片1，低温固化预处理，形成PI定向层2。
将两层PET基片1与封胶框3封装成液晶盒，盒内灌注液晶4，即可制得液晶显示面板。
