Description

液晶显示装置 技术领域
本发明涉及显示技术领域，特别涉及一种液晶触控显示装置。
 背景技术
低温多晶硅液晶显示器(low temperature poly-silicon thin film transistor liquid crystal display, LTPS TFT-LCD)以其高迁移率，良好的充电能力而备受关注，但其工艺复杂，制程控制极为严格。近年来，基于LTPS的内嵌式触控面板(In-cell touch panel, In-cell TP)也越来越受到人们与设计者们的关注。然而由于较多的虚拟线(Dummy Line)，导致其集成电路(integrated circuit, IC)端的端口较为复杂，端口数也繁多，这将大大增加了IC的负载，同时也增加了设计的复杂程度，因此优化简单的虚拟线(Dummy Line)是目前技术上需要达成的目标。
图1是现有技术中低温多晶硅液晶显示器10的结构示意图。传感单元20(或称触控单元、sensing units 或 sensor pad)一般采用金属层作为金属走线，在相邻两列传感单元之间插入一根虚拟线30(Dummy Line)，并与相邻右侧的第一个传感单元20相连接，即将虚拟线30与右侧相邻的传感单元20相连，同时虚拟线30的末端，即集成电路(integrated circuit, IC)对侧端的传感单元处于断开状态。所述虚拟线的配置存在着以下缺陷：(1)由于虚拟线由第一个传感单元20引出，故第一个传感单元20的电阻电容负载(Resistance capacitance loading, RC Loading)较其他传感单元大，进而影响第一个传感单元的灵敏度；(2)在显像功能时，该虚拟线30与公共驱动信号电位(Vcom)连接，产生防串扰信号(anti-crosstalk signal)的作用；在显像功能时，虚拟线由第一个传感单元20引出，该虚拟线会对其旁边的传感单元20产生干扰。
故，有必要提出一种新的技术方案，以解决上述技术问题。
 技术问题
本发明的目的在于提供一种显示装置，其能提高显示面板的触控灵敏度。
 技术解决方案
一种液晶显示装置，所述液晶显示装置包括: 多个传感单元，排列成传感单元的一阵列； 多条虚拟线，每条设置于两列的多个所述传感单元之间，其中所述各虚拟线具有多个虚拟线单元, 每一虚拟线单元与一传感单元一对一对应，并电性连接所述一传感单元。
根据本发明的一个实施例的进一步特征，所述每一虚拟线单元与所述一传感单元的一开始端、一中间段与一末端电性连接。
根据本发明的一个实施例的进一步特征，所述每一虚拟线单元配置为一E字型结构，以与所述一传感单元的所述开始端、所述中间段与所述末端电性连接。
根据本发明的一个实施例的进一步特征，所述传感单元和虚拟线为透明导电材料制成。
根据本发明的一个实施例的进一步特征，所述传感单元为透明导电材料制成，所述传感单元与一公共驱动信号电位连接。
根据本发明的一个实施例的进一步特征，在显像功能时，所述虚拟线和所述传感单元位于所述公共驱动信号电位。
一种低温多晶硅液晶显示装置，所述低温多晶硅液晶显示装置包括:多个传感单元，排列成传感单元的一阵列；多条虚拟线，每条设置于两列的多个所述传感单元之间，其中所述各虚拟线具有多个虚拟线单元, 每一虚拟线单元与一传感单元一对一对应，并电性连接所述一传感单元的一开始端、一中间段与一末端电性连接。
根据本发明的一个实施例的进一步特征，所述每一虚拟线单元配置为一E字型结构，以与所述一传感单元的所述开始端、所述中间段与所述末端电性连接。
根据本发明的一个实施例的进一步特征，所述传感单元和虚拟线为透明导电材料制成。
根据本发明的一个实施例的进一步特征，所述传感单元为透明导电材料制成，所述传感单元与一公共驱动信号电位连接。
根据本发明的一个实施例的进一步特征，在显像功能时，所述虚拟线和所述传感单元位于所述公共驱动信号电位。
 有益效果
相较于现有虚拟线的配置(如图1所示)，本发明在显示装置运作时，由于虚拟线不仅是由第一个传感单元引出，而是各虚拟线单元由其对应的传感单元引出，因此各传感单元的电阻电容负载(Resistance capacitance loading, RC Loading)接相近，而提升传感单元的灵敏度；另外，将虚拟线分段虚拟线单元后，分别一对一对应并连接到相邻的传感单元，降低显像时，虚拟线单元对其他传感单元的信号串扰，同时维持整个面板的电场均一性，从而可以有效地提高显示装置的触控灵敏度。

本发明的液晶显示装置可以是低温多晶硅液晶显示器(low temperature poly-silicon thin film transistor liquid crystal display, LTPS TFT-LCD)。
请参考图2，其为根据本发明的一第一实施例的液晶显示装置的结构示意图。
本实施例的液晶显示装置110包括: 多个传感单元120，以及多条虚拟线130。所述多个传感单元120排列成传感单元120的一阵列，所述多条虚拟线130，每条设置于两列的多个所述传感单元120之间。所述各虚拟线130被分段成为多个虚拟线单元131, 每一虚拟线单元131与一传感单元120一对一对应，并与右侧相邻的所述一传感单元120电性连接。其中所述每一虚拟线单元配置为一E字型结构与所述一传感单元120的一开始端、一中间段与一末端电性连接。所述传感单元120和虚拟线130为透明导电材料(底置氧化铟锡，bottom indium tin oxide, bottom ITO)制成。且所述传感单元与一公共驱动信号电位(Vcom)连接。因此在显像功能时，所述虚拟线130和所述传感单元120位于所述公共驱动信号电位。
此外提供另一种实施例，请参考图3，其为根据本发明的一第二实施例的液晶显示装置的结构示意图。
本实施例的液晶显示装置210包括: 多个传感单元220，以及多条虚拟线230。所述多个传感单元220排列成传感单元220的一阵列，所述多条虚拟线230，每条设置于两列的多个所述传感单元220之间。所述各虚拟线130被分段成为多个虚拟线单元231, 每一虚拟线单元231与一传感单元220一对一对应，并与左侧相邻的所述一传感单元220电性连接。其中所述每一虚拟线单元配置为一E字型结构与所述一传感单元220的一开始端、一中间段与一末端电性连接。所述传感单元220和虚拟线230为透明导电材料(底置氧化铟锡，bottom indium tin oxide , bottom ITO)制成。且所述传感单元与一公共驱动信号电位(Vcom)连接。因此在显像功能时，所述虚拟线230和所述传感单元220位于所述公共驱动信号电位。因此在此实施例中，传感单元220设置在虚拟线单元231的左侧，也可实现如同第一实施例的触控显示功能。
相较于现有虚拟线的配置(如图1所示)，本发明在显示装置运作时，由于虚拟线不仅是由第一个传感单元引出，而是各虚拟线单元由其对应的传感单元引出，因此各传感单元的电阻电容负载(Resistance capacitance loading, RC Loading)接相近，而提升传感单元的灵敏度；另外，将虚拟线分段虚拟线单元后，分别一对一对应并连接到相邻的传感单元，降低显像功能时，虚拟线单元对其他传感单元的信号串扰，同时维持整个面板的电场均一性，从而可以有效地提高显示装置的触控灵敏度。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
