Description
本发明涉及液晶显示领域，尤其涉及一种紫外光固化设备及框胶固化方法。
液晶显示器（Liquid Crystal Display，LCD）轻、薄、低耗电等优点，被广泛应用于计算机、移动电话及个人数字助理等现代化信息设备。一般来说，液晶显示器包含液晶显示面板及背光模块（backlight
module），由于液晶显示面板自身不会发光，因此液晶显示器必须仰赖背光模块内的光源来发出光线。由背光模块内的光源所发出的光线，经过液晶显示面板的液晶，藉由液晶的转向，来调整传递至使用者的光线强度，进而输出影像。
在制作液晶显示面板时，当阵列基板与彩色滤光片基板制作出来之后，会将两层基板两层基板组立成盒。在成盒之前，阵列基板与彩色滤光片基板之间需要涂布框胶（seal）加以密封与固定。框胶要经过紫外线光先进行预固化，然后通过高温炉中的热固化完成最终的固化。然而，当紫外线对框胶进行预固化时，为防止显示区（active
area, AA）内的液晶和聚酰亚胺（PI）配向膜也被紫外线照射，需要有一层紫外线掩膜板（mask）来遮蔽主动区域的液晶。
请参阅图1，图1为现有液晶显示技术中框胶固化过程的示意图，为了使框胶100固化，同时防止紫外线光源500发出的紫外（UV）光照射到AA区的液晶和PI膜，在框胶100固化过程中，会使用掩膜板600来遮挡UV光，以使得框胶100以外的其他区域不会照射到UV光。但是如图2所示，在实际照光过程中，由于UV光会倾斜入射，即使使用掩膜板600进行遮挡，但一部分UV光还是可以倾斜的照射到AA区的PI膜200表面，UV光会破化PI膜200的表面结构，使PI分子结构的侧链发生变化，从而导致面板在使用过程中预倾角发生变化，最终导致液晶面板在加电情况下，显示区内被照射到UV光的部分，和没有照射到UV光的部分，亮度不同，从而在面板周边出现的一些mura，影响面板的整个显示品味，降低面板的等级。
本发明的目的在于提供一种紫外光固化设备，具有使UV光不能侧向照射到显示区的挡光板，保护了PI配向膜表面，进而减轻了液晶面板的周边mura问题，提升了产品品质。
