Description

内嵌式触摸屏、显示装置及制作方法 技术领域
本发明涉及显示技术领域，特别涉及一种内嵌式触摸屏、显示装置及制作方法。
背景技术
随着显示技术的不断发展，触摸屏逐渐走进了大众的视野。目前，触摸屏可分为外挂式触摸屏和内嵌式触摸屏。其中，外挂式触摸屏的显示模块和触控模块是两个相对独立的器件，通过后端贴合工艺将两个器件整合。内嵌式触摸屏将触控模块嵌入显示模块内，使两个模块合为一体，而不再是两个相对独立的器件，不但可以减薄模组整体的厚度，还可以大大降低触摸屏的制作成本，因此内嵌式触摸屏受到各大厂家的青睐。
内嵌式触摸屏包括由触控驱动(Touch Driving)电极和触摸感应(Touch Sensing)电极组成的触控电极。在分别为触控驱动电极和触摸感应电极施加电压后，二者之间形成电场，实现触摸感应的功能。
目前，内嵌式触控屏的触摸感应方式主要是互电容式，触控电极设置于阵列基板上。参见图1，示出了一种内嵌式触控屏的结构，包括依次层叠设置的阵列基板22、钝化层26、触控电极24、液晶层27、隔垫物23、光学补偿层(OC)25、彩膜基板21，其中，触控电极24均位于阵列基板22侧，由com(common electrode，公电极)及ITO(Indium Tin Oxides，铟锡金属氧化物)分割而成。柱状隔垫物23位于彩膜基板21侧，设置在触控电极24的上表面，用于控制盒厚。手指触控时需穿透液晶层29，感应电容较小，信噪比较低，导致触摸判断的灵敏性和准确性较低。

附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下， 还可以根据这些附图获得其他的附图。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
图2是本发明实施例提供的一种内嵌式触摸屏的结构示意图。参见图2，该内嵌式触摸屏包括：彩膜(Color Filter，彩色滤光片)基板21和Array(阵列)基板22、柱状隔垫物23、触控电极24、OC(Optical Compensation，光学补偿)层25、钝化层(PVX)26、液晶层27。其中，触控电极24包括触控驱动电极241和触摸感应电极242。
其中，柱状隔垫物23形成于Array基板22侧。参见图2，柱状隔垫物23设置于Array基板22侧的PVX26上。即，在制作内嵌式触摸屏时，在制作完毕PVX26后，在PVX26上制作柱状隔垫物23。在本发明实施例中，之所以要在CF基板21和Array基板22之间设置柱状隔垫物23，是因为液晶分子的体积随温度变化而收缩或膨胀，且液晶面板为真空的密闭结构，导致液晶面板在低温状态时出现真空气泡或高温时出现重力缺陷，从而使得液晶层的厚度不均一。而在设置了柱状隔垫物23后，柱状隔垫物23可以支撑CF基板21和Array基板22且保持二者之间的间距，避免具有密闭结构的液晶面板受到外力的作用时， CF基板21和Array基板22相互错位或液晶面板间隙不能及时恢复，从而导致的漏光、画面品质不一的缺陷。
参见图3，图2中的柱状隔垫物23包括顶面231、第一侧面232和第二侧面233。其中，触控电极24铺设于柱状隔垫物23的顶面231、第一侧面232和第二侧面233，第一侧面232与第二侧面233相对。其中，第一侧面232和第二侧面233为紧邻液晶27的侧面。其中，触控驱动电极241铺设于顶面231和第一侧面232上。触摸感应电极242铺设于顶面231和第二侧面233上。
参见图4，在顶面231上触控驱动电极241和触摸感应电极242是间隔铺设的。图4中的圆形区域为柱状隔垫物部分。在图4中触控驱动电极241和触摸感应电极之间形成有间隙(slit)部分30。为了明确触控电极的铺设结果，本发明实施例提供了图4中AA’部分的截面示意图，参见图5；图4中BB’部分的截面示意图，参见图6。由图5和图6可知，从不同的角度查看铺设的触控电极，结果是不一样的。在图5中，柱状隔垫物的顶面铺设有触控驱动电极和触摸感应电极，两个侧面均铺设的触摸感应电极。在图6中，柱状隔垫物的顶面铺设有触控驱动电极和触摸感应电极，两个侧面一面铺设有触摸感应电极、一面铺设有触控驱动电极。
其中，触控原理为：在对触控驱动电极241加载触控驱动信号时，检测触控感应电极242通过互电容耦合出的感应电压信号.在此过程中，若有人体接触内嵌式触摸屏，则人体电场便会作用在互电容上，使互电容的电容值发生变化，从而改变触控感应电极242通过互电容耦合出的感应电压信号，进而根据该感应电压信号的变化，确定触点位置。由于本发明实施例中的触控驱动电极241和触摸感应电极242覆盖在柱状隔垫物23之上，因此互电容会增加。手指触控时感应电容也会增大，且能减小液晶层对触控的影响。
在本发明实施例中，柱状隔垫物23可全部被触控电极24覆盖。即，柱状隔垫物23的顶面231、第一侧面232和第二侧面233除间隙部分30外全部铺设有触控电极24。柱状隔垫物23可部分被触控电极24覆盖。即，柱状隔垫物23 的顶面231、第一侧面232和第二侧面233均部分铺设有触控电极24。比如，顶面231上的50％区域、第一侧面232上的50％区域、第二侧面233上的50％区域铺设有触控电极24。本发明实施例对此不进行具体限定，可视情况而定。
此外，除了柱状隔垫物23上铺设有触控电极24外，PVX26上也铺设有触控电极24。在图2中，与第一侧面231相连的第一区域261铺设有触控驱动电极241，与第二侧面232相连的第二区域262铺设有触摸感应电极242。其中，该第一区域261和第二区域262均是PVX上的区域。
本发明实施例提供的内嵌式触摸屏，在柱状隔垫物上铺设触控电极，增大了触控电极的表面积，使得触控驱动电极和触摸感应电极之间的互电容增大，从而手指触控时产生的感应电容也会增大，同时减少了液晶层对触控的影响，提高了信噪比，提升了触摸判断的灵敏性和准确性。
本发明实施例还提供了一种显示装置。该显示装置包括上一个实施例所示的内嵌式触摸屏。
本发明实施例提供的显示装置，在柱状隔垫物上铺设触控电极，增大了触控电极的表面积，使得触控驱动电极和触摸感应电极之间的互电容增大，从而手指触控时产生的感应电容也会增大，同时减少了液晶层对触控的影响，提高了信噪比，提升了触摸判断的灵敏性和准确性。
