Description

压力触控式液晶显示装置及其制作方法
技术领域
本发明属于触控显示领域，更具体地说，涉及一种压力触控式液晶显示装置及其制作方法。
背景技术
近年来，随着智能手机、平板电脑、电视等中小型电子产品的发展，用户与电子产品之间的人机交互不再局限于按键或按钮的操作，而是越来越多地需要在显示屏上直接点击或触摸来实现人机交互，触控装置则是直接点击与电子产品进行交互的平台，于是压力触控(force touch)技术便应运而生。实现压力触控功能的核心部件便是所谓的压力触控膜(force film)，这种压力触控膜通常可以是采用丝网印刷的工艺打印上特定的实现压力触控功能的氧化铟锡图案(ITO pattern)，如图1所示，可通过在薄膜基板121上印刷传感器阵列122来形成压力触控薄膜120。
如图2所示，现有的压力触控式液晶显示装置100一般包括触控面板(TP)131、LCD模组132和背光模组133。触控面板131可通过胶黏剂150粘合到LCD模组132。压力触控膜120通常被设置于液晶显示(LCD)模组的中框(或中框支架)110的上表面上，与LCD模组中的公共电压(VCOM)电极共同形成压力电容。
由于上述结构的压力触控式液晶显示装置需要以LCD模组132中的VCOM ITO 134作为压力电容的另一电极。但VCOM ITO 134又是显示和某些嵌入式TP所需要的，因此就会存在信号干扰的问题。另一方面，这种结构的触控面板部分与LCD模组的显示部分本身也会存在信号干扰，影响TP的信噪比(SNR)。因此，鉴于上述现有技术中所存在的不良问题，迫切需要开发一种能够减小信号干扰的触控技术。
发明内容
为克服现有技术中存在的上述不良问题，本发明的示例性实施例提供一种压力触控式液晶显示装置，所述压力触控式液晶显示装置能够有效地避免压力触控与显示之间的信号干扰，提升压力触控品质。

优选地，所述屏蔽金属层可设置在彩色滤光基板的面对液晶层的表面上。
根据本发明的示例性实施例另一方面，提供一种压力触控式液晶显示装置的制造方法，所述制造方法包括如下步骤：在触控面板的一个表面上形成压力触控膜；依次叠置薄膜晶体管基板、液晶层和彩色滤光基板，形成液晶显示模组；在彩色滤光基板的一个表面上设置屏蔽金属层；使压力触控膜面对液晶显示模组而将触控面板与液晶显示模组彼此贴合。
优选地，触控面板可通过设置在外围的胶黏剂与液晶显示模组彼此贴合，并在触控面板与液晶显示模组之间可形成空气层。
优选地，所述压力触控膜和屏蔽金属层可形成压力电容，并且压力触控膜和屏蔽金属层可分别构成所述压力电容的两个电极。

将在接下来的描述中部分阐述本发明另外的方面和/或优点，一部分将通过描述而变得清楚，或者可以经过本发明的实施而得知。
附图说明
通过下面结合附图进行的对实施例的描述，本发明的上述和/或其它目的和优点将会变得更加清楚，其中：
图1是压力触控膜的示意图；
图2是现有技术中的压力触控式液晶显示装置的示意图；
图3是根据本发明的示例性实施例的压力触控式液晶显示装置的示意图；
图4是根据本发明的另一示例性实施例的压力触控式液晶显示装置的示意图。
具体实施方式
现将详细描述本发明的示例性实施例，所述实施例的示例在附图中示出，其中，相同的标号指示相同或相似的部件。以下将通过参照附图来说明所述实施例，以便解释本发明。在此需要说明的是，提供附图仅为了帮助本领域技术人员充分地了解根据本发明的示例性实施例的液晶显示装置的结构及其工作原理，并非意在限制本发明。
图3是根据本发明的示例性实施例的压力触控式液晶显示装置300的示意图。
在本示例中，压力触控式液晶显示装置300包括液晶显示(LCD)模组、屏蔽金属层340、压力触控膜350和触控面板(TP)360。其中，LCD模组可包括依次叠置的薄膜晶体管(TFT)基板310、液晶层320和彩色滤光(CF)基板330，压力触控膜350可形成在触控面板360的面对LCD模组的一个表面(例如，图3中所示的下表面)上。优选地，压力触控膜350可通过丝网印刷工艺形成在触控面板360的下表面上。在本示例中，压力触控膜350可由氧化铟锡(ITO)形成。即，压力触控膜350可为通过丝网印刷工艺形成在触控面板360的下表面上的ITO图案。然而，形成压力触控膜350的材料不限于此，压力触控膜350也可由其他透明导电材料形成。
在本示例中，屏蔽金属层340可设置于彩色滤光基板330的面对压力触控膜350的一侧。也就是说，屏蔽金属层340可设置于彩色滤光基板330的上侧(即，外侧)。屏蔽金属层340可由ITO形成。然而，形成屏蔽金属层340的材料不限于此，屏蔽金属层340也可由其他透明导电材料形成。
其中，在压力触控膜350面对LCD模组的状态下，将触控面板360通过设置在外围的胶黏剂390与LCD模组通过一次贴合而彼此结合，并且在触控面板360与LCD模组之间留有很薄的一层空气层(或气隙)。更具体地说，在压力触控膜350与屏蔽金属层340之间留有空气层，如此便可利用这层空气层去构成实现压力电容所需的绝缘介质。
这里，胶黏剂390采用光学胶，例如，透明光学胶(OCA胶)或透明光学树脂胶(OCR胶)，但本发明不限于此。也可以采用其他类型的胶黏剂，只要所述胶黏剂的粘合性强且不影响光学透过率即可。
压力触控膜350和屏蔽金属层340可形成压力电容。具体地，参照图3，压力触控膜350可充当压力电容的上电极，屏蔽金属层340可充当压力电容的下电极，两者之间形成的空气层可充当压力电容中间的绝缘介质层，如此便形成一个良好的压力触控结构。
由于这种压力触控结构具有屏蔽金属层340作为压力电容的独立的电极，而不使用LCD模组中的公共电压电极(VCOM ITO)380作为压力电容的一个电极，可有效地解决现有技术中利用VCOM ITO作为压力电容的一个电极所导致的信号干扰的问题，从而有效地避免压力触控与显示之间的信号干扰，提升压力触控式液晶显示装置的压力触控品质。
此外，由于屏蔽金属层340不仅可以用作压力电容的下电极，而且可以用作屏蔽层，以良好地避免LCD显示信号与TP信号之间的干扰问题，从而可保证显示和触控的精准度。
作为示例，压力触控式液晶显示装置300还可包括保护盖板370，设置在触控面板360的外侧，并用于保护触控面板360免受由外界环境等引起的影响和损坏。在此，保护盖板370可以是强化玻璃盖板、塑料盖板、聚甲基丙烯酸甲酯(PMMA)盖板等。
图4是根据本发明的另一示例性实施例的压力触控式液晶显示装置300’的示意图。
如图4所示，该示例性实施例的压力触控式液晶显示装置300’与上面参照图3所描述的压力触控式液晶显示装置300的不同之处仅在于：屏蔽金属层340’设置在彩色滤光基板330’的面对液晶层320’的另一表面(即，如图4中所示的下表面)上。在图3和图4中，相似的标号指示相同或相似的元件，例如，标号350和350’均代表压力触控膜，标号340和340’均指示屏蔽金属层等。为了使描述更加简洁，将省略与上面所描述的内容相同或相似的描述。
下面将参照图3和图4描述一种制作具有上述结构的压力触控式液晶显示装置的方法可包括如下步骤：在触控面板360的一个表面上形成压力触控膜350；依次叠置薄膜晶体管基板310、液晶层320和彩色滤光基板330，形成LCD模组；在彩色滤光基板330的一侧设置屏蔽金属层340；使压力触控膜350面对LCD模组而将触控面板360通过设置在外围的胶黏剂390与LCD模组彼此贴合，并且在触控面板360与LCD模组之间形成空气层。
在一个示例中，可将屏蔽金属层340设置在彩色滤光基板330的面对触控面板360的一侧(参照图3)。在另一示例中，可将屏蔽金属层340’设置在彩色滤光基板330’的面对液晶层320’的另一侧(参照图4)。
压力触控式液晶显示装置的制作方法还可包括：在触控面板360上(即，外侧)设置保护盖板370，以保护触控面板360免受诸如撞击等外界环境的影响。
如上所述的压力触控式液晶显示装置这样来实现触控功能：当手指以不同大小的压力去触摸触控面板360时，由于压力触控膜350的形变程度不同，引起压力电容的间距大小的不同，进而引起压力电容量的变化，电容量的变化转化成电信号的变化，电信号的变化传递到触控集成电路(IC)的处理器中，处理器由此定位压力触摸的位置和信号，最终发出特定的指令，让中小型电子产品(诸如智能手机、平板电脑、穿戴式智能手表等)执行特定的动作。
根据以上描述可知，根据本发明的示例性实施例的压力触控式液晶显示装置能够有效地解决目前压力触控结构中利用VCOM ITO作为压力电容的一个电极所导致的信号干扰的问题，从而可提升压力触控的品质。此外，屏蔽金属层除了可作为压力电容的一个电极之外，还可用作屏蔽层，以良好地避免LCD显示信号与TP信号之间的干扰问题，从而保证显示和触控的精准度。
本发明的以上示例性实施例仅仅是作为示例，而本发明并不受限于此。本领域技术人员应该理解：在不脱离本发明的原理和精神的情况下，可对这些实施例进行改变，其中，本发明的范围在权利要求及其等同物中限定。
