Description

触控面板 技术领域
本发明属于触控面板技术领域，具体地讲，涉及一种能够将连接导线的阻抗调节成一致的触控面板。
背景技术
触控面板是允许用户使用手指或者物体通过选择显示在图像显示器等的屏幕上的指令内容来输入用户的指令的输入设备。用户的手或者物体在接触位置处直接与触控面板相接触。由于这种触控面板可以代替连接到图像显示器的诸如键盘或鼠标之类的独立输入设备，所以其应用领域已经日益扩大。
按照触控面板的工作原理，可以将触控面板分为四种，它们分别为电阻式触控面板、电容式触控面板、红外线式触控面板以及表面声波式触控面板。近年来，以具有多点触控(Multi-Touch)功能的电容式触控面板最为受到瞩目。
传统的电容式触控面板包括触控单元阵列，触控单元阵列包括多条X方向感测串列及多条Y方向感测串列。其中，X方向感测串列与Y方向感测串列各包含多个感测垫，因此能够精准感测到用户的触碰位置。在X方向感测串列与Y方向感测串列的交错处，采用桥接线连接两个相邻的感测垫。如此可避免X方向感测串列与Y方向感测串列在交错处翻身短路。
当控制器在处理各连接导线传回的触摸信号时，触摸位置的感测精准度会受到各连接导线的阻抗大小的影响。在现有技术中，通常是将每条X方向感测串列通过对应的一条连接导线直接连接至控制器，且将每条Y方向感测串列也通过对应的一条连接导线直接连接至控制器。然而，由于触控面板空间位置的关系，使得各连接导线到控制器的距离不同，即各连接导线的长短不同，从而各连接导线的阻抗大小不同，进而降低触摸位置的感测精准度。
发明内容
为了解决上述现有技术存在的问题，本发明的目的在于提供一种触控面板，包括：基板、触控单元阵列、多条连接导线、阻抗调节单元及控制器，所述触控单元阵列、所述多条连接导线、所述阻抗调节单元及所述控制器均设置于所述基板上，所述触控单元阵列通过所述多条连接导线连接至所述阻抗调节单元，所述阻抗调节单元连接至所述控制器，所述阻抗调节单元对每条连接导线的阻抗进行调节，以使每条连接导线的阻抗相同。
进一步地，所述阻抗调节单元包括：多个电阻并联单元，其中，每条连接导线连接至对应的电阻并联单元，所述多个电阻并联单元均连接至所述控制器。
进一步地，所述电阻并联单元包括：多个可控开关及并联的多个电阻，其中，每个电阻通过对应的可控开关连接至所述控制器。
进一步地，所述触控面板还包括：开关控制单元，其中，所述开关控制单元设置于所述基板上，且所述开关控制单元用于控制所述可控开关打开或闭合。
进一步地，所述阻抗调节单元及所述开关控制单元均内嵌于所述控制器中。
进一步地，所述基板为彩色滤光片基板或薄膜晶体管阵列基板。
进一步地，所述触控单元阵列包括：多个第一方向感测串列，所述多个第一方向感测串列彼此分离，每个第一方向感测串列包括串接的多个第一感测垫以及多条第一桥接线，每条第一桥接线串接相邻的第一感测垫，每个第一方向感测串列通过对应的连接导线连接至所述阻抗调节单元；多个第二方向感测串列，所述多个第二方向感测串列彼此分离，每个第二方向感测串列包括串接的多个第二感测垫以及多条第二桥接线，每条第二桥接线串接相邻的第二感测垫，每个第二方向感测串列通过对应的连接导线连接至所述阻抗调节单元；其中，所述第一桥接线与所述第二桥接线被配置在不同层别。
进一步地，所述第一感测垫、所述第二感测垫以及所述第一桥接线被配置在同一层别。
进一步地，所述第一感测垫、所述第二感测垫以及所述第二桥接线被配置在同一层别。
进一步地，所述第一感测垫和/或所述第二感测垫的形状为菱形、梯形、十字形、三角形、正六边形或正五边形。
本发明的触控面板，将每条连接导线的阻抗大小调节为相同，以提高触控面板的触摸位置的感测精准度。

触控单元阵列20包括多个第一方向感测串列21及多个第二方向感测串列22。
第一方向感测串列21大体上朝第一方向X延伸。这些第一方向感测串列21彼此分离，换句话说，两个相邻的第一方向感测串列21未相互接触。每个第一方向感测串列21包括串接的多个第一感测垫211以及多条第一桥接线212，每条第一桥接线212串接两个相邻的第一感测垫211。此外，在本实施例中，第一方向感测串列21的数量是以3个为例，但本发明并不局限于此，第一方向感测串列21的数量可大于3个。
第二方向感测串列22大体上朝第二方向Y延伸。这些第二方向感测串列22彼此分离，换句话说，两个相邻的第二方向感测串列22未相互接触。每个第二方向感测串列22包括串接的多个第二感测垫221以及多条第二桥接线222，每条第二桥接线222串接两个相邻的第二感测垫221。此外，在本实施例中，第二方向感测串列22的数量是以4个为例，但本发明并不局限于此，第二方向感测串列22的数量可大于4个。这里，将第一感测垫211与第二感测垫221配置在不同层别。
每个第一方向感测串列21通过对应的一条连接导线30连接至阻抗调节单元40，每个第二方向感测串列22通过对应的一条连接导线30连接至阻抗调节单元40。也就是说，连接导线30的数量等于第一方向感测串列21的数量与第二方向感测串列22的数量之和。
阻抗调节单元40连接至控制器50。在本实施例中，阻抗调节单元40内嵌于控制器50中，以提高控制器50的集成度，但本发明并不局限于此，阻抗调节单元40也可直接置于基板10上，从而外置于控制器50。这样，阻抗调节单元40对每条连接导线30的阻抗大小进行调节，以使每条连接导线30的阻抗大小相同，从而提高触摸位置的感测精准度。
由于根据本发明的实施例的控制器50中的其他部件与现有技术相同，所以在此不再赘述。以下将对根据本发明的实施例的阻抗调节单元40进行详细的描述。根据本发明的实施例的阻抗调节单元40的内部配置如图2所示。
参照图1和图2，根据本发明的实施例的阻抗调节单元40包括多个电阻并联单元41。每个第一方向感测串列21通过对应的一条连接导线30连接至对应的一个电阻并联单元41，每个第二方向感测串列22通过对应的一条连接导线30连接至对应的一个电阻并联单元41。也就是说，电阻并联单元41的数量等于第一方向感测串列21的数量与第二方向感测串列22的数量之和。
每个电阻并联单元41均内置于控制器50中，由于每个电阻并联单元41与控制器50内的其他部件连接，因此可以理解为每个电阻并联单元41都连接至控制器50。
如此，控制器50通过调节每个电阻并联单元41的阻抗大小，以达到调节每条连接导线30的阻抗大小的目的。
根据本发明的实施例的电阻并联单元41包括多个可控开关411及并联的多个电阻器412，其中，每个电阻器412通过对应的一个可控开关411连接至控制器50。这样，控制器50通过控制每个可控开关411的打开或闭合状态，以控制每个电阻并联单元41的整体阻抗大小，从而调节每条连接导线30的阻抗大小。此外，在本实施例中，每个电阻并联单元41中的电阻器412的数量是以3个为例，但本发明并不局限于此，每个电阻并联单元41中的电阻器412的数量可大于3个。
为此，根据本发明的实施例的触控面板还可包括开关控制单元60。在本实施例中，开关控制单元60内嵌于控制器50中，以提高控制器50的集成度，但本发明并不局限于此，开关控制单元60也可直接置于基板10上，从而外置于控制器50。开关控制单元60接受控制器50的控制，以控制每个可控开关411的打开或闭合状态。
此外，应当说明的是，在根据本发明的实施例中，第一感测垫211与第二感测垫221彼此措置且未重叠或接触，且被配置成与第一桥接线212或第二桥接线222同一层别。但本发明并不限制于图1示出的第一感测垫211与第二感 测垫221的位置关系，在本发明的其他实施方式中，例如，第一感测垫211与第二感测垫221也可被配置成不同层叠，且第一感测垫211与第二感测垫221可在空间上重叠，也就是说，第一感测垫211与第一桥接线212可经由图案化相同的导电层而形成，第二感测垫221与第二桥接线222可经由图案化相同的另一导电层而形成。
根据本发明的实施例的基板10可例如是单层的玻璃基板、石英基板或塑胶基板。在本发明的其他实施方式，基板10为彩色滤光片基板或薄膜晶体管阵列基板。以下将详述基板彩色滤光片基板或薄膜晶体管阵列基板的多个实施方式。
图3至图5是根据本发明的数个实施例的触控显示面板的剖切示意图。
参照图3至图5，触控显示面板10a至10c包括触控单元阵列20、彩色滤光片基板102、薄膜晶体管阵列基板104以及显示材料层106，其中，显示材料层106夹设于彩色滤光片基板102与薄膜晶体管阵列基板104之间。
如图3所示，触控单元阵列20设置于彩色滤光片基板102的内表面上。如图4所示，触控单元阵列20设置于彩色滤光片基板102的外表面上。如图5所示，触控单元阵列20设置于薄膜晶体管阵列基板104的内表面上。然而，本发明并不局限于此，若将薄膜晶体管阵列基板104设计成整合彩色滤光片与薄膜晶体管阵列的基板(Color Filter On Array，COA)，彩色滤光片基板102即可替换为无彩色滤光片的基板。
显示材料层106的材料例如为非自发光材料、自发光材料或其他合适的材料。非自发光材料例如为液晶、电泳或其他合适的材料。自发光材料例如为有机发光材、无机发光材或其他合适的材料。换句话说，触控显示面板10a至10c可以是液晶显示面板，也可以是有机发光显示面板，或者是电泳显示面板。
此外，在根据本发明的实施例中，第一感测垫211和/或第二感测垫221的形状均为菱形(如图1所示)。但本发明并不限制于此，参照图6a至图6e，第一感测垫211和/或第二感测垫221的形状也可例如是梯形(如图6a所示)、十字形(如图6b所示)、三角形(如图6c所示)、正六边形(如图6d所示)或正五边形(如图6e所示)。
尽管已经参照其示例性实施例具体显示和描述了本发明，但是本领域的技术人员应该理解，在不脱离权利要求所限定的本发明的精神和范围的情况下，可以对其进行形式和细节上的各种改变。
