Description

液晶显示器及其显示模组、TFT阵列基板 【技术领域】
本发明涉及液晶显示的技术领域，具体是涉及一种液晶显示器及其显示模组、TFT阵列基板。
【背景技术】
液晶显示器是目前使用最广泛的一种平板显示器，已经逐渐成为各种电子设备如移动电话、个人数字助理(PDA)、数字相机、计算机屏幕或笔记本电脑屏幕所广泛应用具有高分辨率彩色屏幕的显示器。随着液晶显示器技术的发展进步，人们对液晶显示器的显示品质、外观设计、低成本和高穿透率等提出了更高的要求。
IPS(平面控制模式)广视角技术的液晶显示让观察者任何时候都只能看到液晶分子的短轴，因此在各个角度上观看的画面都不会有太大差别，这样就比较完美地改善了液晶显示器的视角。第一代IPS技术针对TN模式的弊病提出了全新的液晶排列方式，实现较好的可视角度。第二代IPS技术(S-IPS即Super-IPS)采用人字形电极，引入双畴模式，改善IPS模式在某些特定角度的灰阶逆转现象。第三代IPS技术(AS-IPS即Advanced Super-IPS)减小液晶分子间距离，提高开口率，获得更高亮度。

其中，TG1、TG2、TG3...是第一种Gate line信号，用于控制触控TFT；G1、G2、G3...是第二种Gate line信号，用于控制图像显示TFT；D1、D2、D3...是Date line信号，用于控制触控信号或图像信号的输入或输出；D1、D2、D3...用于控制触控信号时，奇数条做Tx使用，偶数条做Rx使用；TG和G表示用于驱动两种TFT，与图3和图5实施例中两种TFT无特定对应关系，对应关系可互换。
相对于现有技术，本发明提供的TFT阵列基板，通过在每一阵列单元中设置两个TFT，且两个TFT与不同的gate line连接，分别用于控制画面显示以及控制触控功能，可以实现液晶显示器像素的触控功能。
另外，本发明实施例还提供一种液晶显示模组及其液晶显示器，该液晶显示模组包括上述实施例中所述的具有触控控制功能的TFT阵列基板。请参阅图 8，图8是本发明液晶显示器一优选实施例的结构示意简图。其中，该液晶显示器包括壳体8以及设于壳体8内部的上述实施例中的液晶显示模组。关于液晶显示模组中具有触控控制功能的TFT阵列基板的技术特征请参阅上述实施例中的详细描述，而液晶显示器的其他部分结构技术特征，在本领域技术人员的理解范围内，此处亦不再赘述。
相对于现有技术，本发明提供的液晶显示模组及其液晶显示器，通过在TFT阵列基板的每一阵列单元中设置两个TFT，且两个TFT与不同的gate line连接，分别用于控制画面显示以及控制触控功能，可以实现液晶显示器像素的触控功能。
以上所述仅为本发明的部分实施例，并非因此限制本发明的保护范围，凡是利用本发明说明书及附图内容所作的等效装置或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
