Description

一种触控单元、阵列基板、液晶成盒基板及触控显示器
技术领域
本发明涉及触控显示技术领域，尤其涉及一种触控单元、阵列基板、液晶成盒基板及触控显示器。
背景技术
In cell touch（内嵌式触摸）液晶显示器是将触控单元制作在液晶显示器的第一层玻璃，即TFT（Thin Film Transistor，薄膜场效应晶体管）阵列基板上。
其中，电容式的In cell touch液晶显示器的工作原理是，通过触控改变触控单元上的触控电容，触控单元将触控电容的变化会转换成电压的变化并通过读取感应线传输给外部信号处理单元。因此，外部信号处理单元可以探测到这个电压的变化，从而实现触控的定位。
现有的In cell touch液晶显示器中，触控单元的信号稳定性较差。
发明内容
本发明的目的是提供一种触控单元、阵列基板、液晶成盒基板及触控显示器，以解决现有的触控单元信号稳定性较差的问题。
本发明的目的是通过以下技术方案实现的：
一种触控单元，包括：
多个触控子单元，每个触控子单元包括：触控薄膜场效应晶体管TFT、感应电容、读取感应线、和存储电容，所述存储电容的电容量小于所述感应电容的电容量；
所述触控TFT的栅极连接阵列基板的栅线；
所述触控TFT的漏极连接所述读取感应线；
所述感应电容的一端连接所述触控TFT的源极；
所述存储电容的一端连接所述触控TFT的源极，另一端连接稳压电极。
一种阵列基板，包括：
上述的触控单元。
一种液晶成盒基板，包括：
上述的触控单元。
一种触控显示器，包括：
上述的。
由于增加了存储电容来稳定触控TFT的电压，降低了噪声对触控TFT电压的干扰，有效提高了触控单元的信号稳定性。又由于触控单元中的触控TFT共用阵列基板的栅极，简化了电路实现结构，降低了器件制造成本。
附图说明
图1为本发明实施例提供的一种触控单元的电路结构示意图。
具体实施方式
本发明提供了一种触控单元，其主要实现结构如下：
多个触控子单元，每个触控子单元包括：触控TFT、感应电容、读取感应线、和存储电容。
其中，上述存储电容的电容量小于上述感应电容的电容量，以保证感应电容的电容大小发生变化时，能够引起触控TFT的电压跳变，进而实现触控寻址。
各个器件之间的连接关系可以是：触控TFT的栅极连接阵列基板的栅线；触控TFT的漏极连接读取感应线；感应电容的一端连接触控TFT的源极；存储电容的一端连接触控TFT的源极，另一端连接稳压电极。
由于TFT的漏极和源极可对调，因此各个器件之间的连接关系还可以是：触控TFT的栅极连接阵列基板的栅线；触控TFT的源极连接读取感应线；感应电容的一端连接触控TFT的漏极；存储电容的一端连接触控TFT的漏极，另一端连接稳压电极。
上述的存储电容的一端连接稳压电极，另一端连接触控TFT的源极或漏极。其中，稳压电极可以是阵列基板的公共电极，也可以是彩膜基板的公共电极，还可以是其他能够提供稳定电压的电极。因此，在感应电容没有发生变化时，存储电容可以保持触控TFT的电压稳定，降低噪声对触控TFT电压信号造成的影响。
由于增加了存储电容来稳定触控TFT的电压，降低了噪声对触控TFT电压的干扰，有效提高了触控单元的信号稳定性。又由于触控单元中的触控TFT共用阵列基板的栅极，简化了电路实现结构，降低了器件制造成本。
本发明中，定义了像素区域的概念。其中，阵列基板的相邻栅线、相邻数据线交叉对应一个像素区域。
本发明提供的触控单元中，触控子单元的分布可以是：一个像素区域对应设置有一个触控子单元。
为了降低制造成本，简化电路结构，优选的，触控子单元的分布还可以是：多个像素区域设置有一个触控子单元。具体地，可以根据实际的触控感应面积、像素的开口率等情况，确定设置对应一个像素显示子单元的像素区域的数量。例如，如果实际的触控感应面积较大，则可以在较多个像素区域对应设置一个触控子单元，否则，可以在较少的像素区域对应设置一个触控子单元。如果像素的开口率较高，则可以在较多个像素区域对应设置一个触控子单元，否则，可以在较少的像素区域对应设置一个触控子单元。
下面将结合附图对本发明提供的触控单元进行详细说明。
图1是集成了本发明提供的触控单元的一种阵列基板电路结构示意图。其中，Gn-1、Gn和Gn+1表示阵列基板栅极扫描线（即栅线），Dm-1、Dm和Dm+1表示阵列基板的数据线，Vcom表示阵列基板上的公共电极，TS表示Sensor TFT（即触控TFT），CS表示感应电容（Sensor Capacitance），其电容大小能够根据触控显示器表面触摸情况来改变，Cst表示存储电容，Tread表示读取感应线。Cst电容量小于CS的电容量。
相邻的栅线和数据线交叉对应一个像素区域。例如，图1虚线框中相邻的两条栅线与相邻的两条数据线交叉形成的区域对应一个像素区域。阵列基板的像素TFT和触控TFT共用阵列基板的栅线。具体的，在图1中，一个像素区域设置有一个触控子单元，并且这个触控子单元的TS的栅极连接阵列基板的栅线Gn。另外，TS的漏极连接Tread，CS的一端连接TS的源极，Cst的一端连接TS的源极，另一端连接阵列基板的公共电极；或者，TS的源极连接Tread；CS的一端连接TS的漏极；Cst的一端连接TS的漏极，另一端连接阵列基板的公共电极。
应当指出的是，图1中仅示出一个像素区域对应设置的触控子单元，其他像素区域对应设置的触控子单元未示出。
还应当指出的是，图1中仅示出TS的栅极连接阵列基板的栅线Gn的情况，另外，TS的栅极或者可以连接阵列基板的栅线Gn-1。
如果阵列基板的每个像素区域对应设置一个触控子单元。那么，在阵列基板上相邻的两条栅线及相邻的两条数据线交叉对应的一个像素区域设置的触控子单元，其触控TFT的栅极连接相邻的栅线之间的任一条。例如图1所示的连接关系。
如果多个像素区域对应设置一个触控子单元。那么，在TFT阵列基板的栅线Gn’、栅线Gn、数据线Dm’、数据线Dm之间对应的像素区域中设置的触控子单元，其触控TFT的栅极连接从Gn’到Gn的任一栅线。其中，栅线Gn’与栅线Gn为位置不相邻的栅线，数据线Dm’与数据线Dm为位置不相邻的数据线。栅线Gn’与栅线Gn之间相隔的栅线数量，与数据线Dm’与数据线Dm之间相隔的数据线数量相同或不同。
例如图1中，Gn-1、Gn+1、Dm-1、Dm+1之间对应的像素区域内设置一个触控子单元，则这个触控子单元的连接方式可以如图1所示。
触控显示器工作时，栅线按照一定的周期进行扫描，并且逐行打开各行栅线上的TS。由于Cst的存在，当栅线打开Ts的时候，Tread上接收到稳定的电压信号V1。当触控显示器表面发生触摸导致Cs变化时，与Cs连接TS的一端电压突变至V2，这时候，Tread上接收到这个突变信号，通过外部信号处理单元即可得知触摸发生位置，实现了触控寻址的功能。
本发明还提供一种阵列基板，其实现结构中包括上述任一实施例提供的触控单元。本发明中，阵列基板可以但不仅限于是TFT阵列基板。
本发明还提供一种液晶成盒基板，其实现结构中包括上述任一实施例提供的触控单元。还包括阵列基板、彩膜基板等结构。
本发明还提供一种触控显示器，其实现结构中包括上述任一实施例提供的阵列基板，或液晶成盒基板。
本发明提供的触控单元具体可以是In cell touch触控单元。
本发明提供的触控显示器具体可以是In cell touch液晶显示器。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
