Description

反射式液晶显示器 技术领域
本发明涉及显示技术领域，尤其涉及一种反射式液晶显示器。
背景技术
随着移动设备及可穿戴应用的逐渐兴起与蓬勃发展，各种应用对轻薄、超级省电的显示器件的需求也不断增加。其中电子墨水显示器件具有超省电超长时间待机的优势，其在电子书应用领域已取得相当的成功，但其在彩色显示及动态显示上仍存在明显劣势，无法实现全彩显示以及无法达到视频播放所需的刷新频率阻碍了电子墨水在可移动及可穿戴设备上的广泛应用。而常规的液晶显示器(Liquid Crystal Display，LCD)及有机电激光显示器(Organic Light-Emitting Diode，OLED)在显示特性上如色彩、分辨率、刷新率可以满足大部分需求，但是它们耗电相对较高，使用在可移动及可穿戴设备上，成为最主要的耗电设备之一，使设备的待机或使用时间受到极大限制。
反射式液晶显示器具有传统LCD的高刷新频率，较好的彩色显示特性，同时不需要背光提供光源，因此具有超级省电的特性，这些特性使其在移动与穿戴设备应用中受到重视。如图1所示，反射式液晶显示器包括相对设置的上基板100与下基板200、位于所述上、下基板100、200之间的液晶层300、及贴附于所述下基板200表面上的反射层400，其中，所述反射层400通常由反射率较高的金属层形成，其可将环境光线中入射到显示器内的光线反射回去，从而为反射式显示器提供一定的显示亮度。进一步的，如图2所示，反射层400一般还需要再进行处理以形成漫反射层400’，使其反射特性由镜面反射转变为漫反射，而形成具有漫反射效果的漫反射层400’一般需要先在反射层400表面进行处理，在其上形成一些突起结构401，然后得到具有凹凸不平表面的金属漫反射层400’，如此一般需要进行一次或多次的光阻涂布、曝光显影等制程，工艺过程相对复杂，成本也较高。
所以有必要寻找新的方法在反射式液晶显示器中形成具有漫反射效果的反射层或结构，以简化制造工艺、降低成本。

本发明的有益效果：本发明提供了一种反射式液晶显示器，包括相对设置的上基板与下基板、位于所述上、下基板之间的液晶层、粘于所述下基板远离液晶层一侧表面的透明胶层、及通过所述透明胶层贴附于所述下基板表面的镜面反射层；贴附镜面反射层所用的透明胶层的透明胶材内含有透明粒子，且透明胶材与透明粒子具有折射率差，从而可实现漫反射的效果，即所述透明胶层与镜面反射层可以结合作为漫反射层，相较于传统的反射式液晶显示器，无需再进行其他制程制作漫反射层，简化了形成漫反射层的制造工艺，降低了制造难度与成本。

所述透明胶层40包含透明胶材41、及混合于透明胶材41内的透明粒子42。
具体的，所述透明粒子42与所述透明胶材41的折射率不同。如图4所示，当环境中的光线经由上基板10与液晶层30穿过下基板20而进入透明胶层40后，由于透明粒子42与所述透明胶材41之间具有折射率差，光线遇到透明粒子42后发生折射，光路发生改变，然后由镜面反射层50将光线反射出去，从而形成漫反射的效果；即本发明的反射式液晶显示器中，贴附镜面反射层50所用的透明胶层40的透明胶材41内含有透明粒子42，且透明胶材41与透明粒子42具有折射率差，从而可实现漫反射的效果，即所述透明胶层40与镜面反射层50可以结合作为漫反射层，相较于传统的反射式液晶显示器，则无需再进行其他制程制作漫反射层，简化了形成漫反射层的制造工艺，降低了制造难度与成本。
具体的，所述镜面反射层50的材料为金属；优选的，所述镜面反射层50的材料为铝、或银。
具体的，所述上基板10为彩膜基板；所述下基板20为薄膜晶体管阵列基板。
具体的，所述反射式液晶显示器应用于移动及可穿戴设备中。
具体的，所述镜面反射层50将环境光线中入射到反射式液晶显示器内的光线反射回去，从而为所述反射式液晶显示器提供一定的显示亮度，因而所述反射式液晶显示器不需要设置背光模组。
综上所述，本发明提供了一种反射式液晶显示器，包括相对设置的上基板与下基板、位于所述上、下基板之间的液晶层、粘于所述下基板远离液晶层一侧表面的透明胶层、及通过所述透明胶层贴附于所述下基板表面的镜面反射层；贴附镜面反射层所用的透明胶层的透明胶材内含有透明粒子，且透明胶材与透明粒子具有折射率差，从而可实现漫反射的效果，即所述透明胶层与镜面反射层可以结合作为漫反射层，相较于传统的反射式液晶显示器，无需再进行其他制程制作漫反射层，简化了形成漫反射层的制造工艺，降低了制造难度与成本。
