Description

一种触控显示设备 技术领域
[0001] 本发明涉及显示触控领域， 特别是指一种釆用触控式的显示设备。
背景技术
[0002] 为了操作上的方便， 人们用触摸屏来代替鼠标或键盘工作时， 我们必须首先用手指 或其它物体触摸安装在显示器前端的触摸屏， 然后系统根据手指触摸的图标或菜单位置来定 位选择信息输入触摸屏由触摸检測部件和触摸屏控制器组成； 触摸检测部件安装在显示器屏 幕前面， 用于检测] ¾户触摸位置， 接受后送触摸屏控制器； 而触摸屏控制器的主要作] ¾是从 触摸点检测装置上接收触摸信息， 并将它转换成触点坐标， 再送给 CPU , 它同时能接收 CPU发来的命令并加以执行。
[0003] 对于上述应用触摸屏技术的数码产品而言其优点主要是将控制键盘与显示屏的功能 进行集合使显示屏同时具有键盘的功能， 这种触摸屏的技术不但可以在有效的面积内尽可能 的增大显示屏的面积， 同时对于整体数码产品的外观效果 m有比较大的提升。 通过上述的触 摸屏的技术可以在不增大数码产品整体体积的前提下尽可能的增大显示屏的尺寸， 而使通 过装置有触摸屏的数码产品播放电视、 动画类视频成为可能。 而就目前市面上出现的触摸屏 而言， 红外式触摸屏占据 -定的份额， 如专利号 200720052423.3 以及专利号 200720051069.2所公开的两种专利产品即为常见的红外触控显示装置， 其主要包括平板显示 部件 （包括液晶显示屏）、 围绕在平板显示部件四周的四块焊接有红外线发射管以及红外线 接收管的印刷电路板、 外框， 其中， 所述红夕卜线发射管以及红外线接收管均设置在所述平板 显示部件的显示面前侧， 且所述红外线发射管与红外线接收管分别相对应的设置在平板显示 部件四周的左右两侧以及上下两侧， 从而使得平板显示部件的显示面前侧形成一个红外线光 栅探测网。 当使用者用手指或其它物体点触平板状显示部件的显示面上某一点时， 便会挡住 经过该位置的两条红外线， 使红外线接收管不能收到与其相对应的红外线发射管所发射的红 外线， 该红外触控显示装置的控制系统便能即时计算出触点的位置， 再根据触点位置对应的 命令运行相应的程序， 从而实现平板显示部件上的触控操作。
[0004] 如上所述的这种结构的红外触控显示装置中的印刷电路板按照与平板状显示部件相 互平行的方式设置， 其结构上存在着一系列的缺陷， 具体叙述如 T:

第二， 为使红外线发射管以及红外线接收管所发射以及接收的红外光线与平板显示部件平 行， 红外线发射管以及红外线接收管需要进行弯胸工序后再焊接安装到印刷线路板上， 或者 是先焊接安装到印刷电路板上， 再进行弯胸， 如此不仅工序复杂， 增加了制造成本， 而― 红 外线发射管以及红外线接收管在弯脚后可能对其寿命及稳定性产生影响。
[0005] 随着社会的不断发展， 目前液晶显示器都向超薄， 超窄方向发展， 按照传统的红外 触摸屏采用边框， 一般都需要二十几毫米宽， 这主要受限于用于连接上述红外线发射管以及 红外线接收管的印刷电路板的排列宽度。 因而造成很多超薄、 超窄的显示器上难以使 ]¾红外 触控的技术。 以上为传统红外触控显示装置在具体实施时所存在的主要技术缺陷， 即为本发 明所要研究解决的主要问题。
