Description

具有触摸控制功能的平板显示屏 技术领域
本'发明涉及一种触摸屏， 尤其是一种具有柔性隔膜电磁感应式触摸控制功 能的平板显示屏。 属于电子电器技术领域。 背景技术
随着计算机技术的广泛普及应用，信息的电子化、数字化途径越来越丰富。 人们使用计算机的各种外设， 发明了各种各样的方法， 完成信息处理最初的数 字化过程。 例如： 各种键盘输入法、 语音录入、 图象采集等等， 其中最有效的、 最便捷的一种是直接在显示屏通过触摸点击等方式进行信息输入、 指令调动。 如， 在利用计算机绘画制图时， 由于利用鼠标操作无法真正如同人们使用笔在 紙面上作画的操作一样的灵活， 而一直障碍人们熟练地完成精美的图案制作。 采用触摸屏， 利用触摸控制笔在显示屏上直接操作，动作就如同在纸面上绘画， 因此整个工作十分容易完成， 效果较好。 再有， 随着便携式产品的不断推出， 各种外设： 键盘、 鼠标都被——省略， 例如 PDA, 基本没有按键的操控， 而全 部是采用触摸控制笔操作触摸屏完成各种操作。
现在的触控板主要采用电阻式方式。 其具体结构是在显示屏的外部设有透 明的触摸膜， 触摸膜的表面涂附一电阻层， 当操作点击触摸膜的具体位置时， 后续的识别控制电路通过计算得知该位置电位的变化， 判断点击的位置坐标， 从而执行相应的操作。 由于现有电阻式在实现大尺寸触控板时， 存在成本高、 工艺复杂、 精度低， 不适合做手写输入等问题， 以及由于多次地操作产生磨损 等物理损伤， 导致触摸膜使用寿命较短等问题， 大大限制了触摸屏的应用。 发明内容
本发明的目的在于克服上述技术的种种不足之处， 提供一种具有触摸控制 功能的平板显示屏， 其制作工艺筒单， 成本低， 识别采集精度高， 而且使用寿 命长。 本发明的目的是这样实现的： 一种具有电磁感应触摸控制功能的显示屏， 它包括平板显示屏本体以及触控感应层， 触控感应层输出接有识别电路， 显示 屏触控操作由电磁输入笔操控。 触控感应层设置在平板显示屏的后面， 其中触 控感应层由电磁感应发生层和底部支撑托层构成， 其中电磁感应发生层的基层 为绝缘柔性隔膜， 隔膜表面印制有电磁感应天线阵列，,、构成柔性隔膜式电磁感 应发生层， 该层的输出接控制识别电路， 输入笔带有电磁波发生装置。 显示屏 为等离子显示屏或液晶显示屏等平板型显示屏。
触控感应层的面积与平板显示屏的面积可不相同。 才艮据不同的需要， 例如 显示屏局部作为触摸输入或触摸操作区域时， 触控感应层的面积可小于平板显 示屏的面积，设置在平板显示屏后面的一侧，也可设置在显示屏的两侧或四周。 当然， 触控感应层的面积也可大于平板显示屏的面积， 这样整个显示屏以及显 示屏的周边均可具有触控的能力。
具体地， 触控感应层为电磁感应发生层， 显示屏隔离了操控笔与感应层， 并不影响感应信号的产生和传递。
电磁感应发生层为分别沿 X、 Y轴分布、 "U" 形天线交叉编排结构的电磁 感应天线阵列。
具体地， 电磁感应发生层的电磁感应天线阵列为在柔性隔膜上电磁感应天 线阵列， 为降低成本电磁感应天线阵列为银浆或银浆与碳浆混合物印刷的电磁 感应天线阵列。
电磁感应天线阵列为单面或双面印刷线路的结构， 也可为一片以上单面的 印刷线路叠置。
为集中设置感应整体装置， 触控感应层的后面设有绝缘屏蔽隔离层， 绝缘 屏蔽隔离层后设有识别电路层。 绝缘屏蔽隔离层与识别电路层之间设有一空间间隙， 可以进一步保证屏蔽 的效果。
再有， 为提高显示屏表面的抗磨损等能力， 在显示屏的正面设有透明的防 护层或防护膜。 根据上述技术方案可知， 本发明具有如下优点：
1、 由于电磁感应层设置在显示屏的后面， 采用柔性隔膜式印刷电磁感应 式阵列天线作为识别感应器件， 因此生产制造容易， 成本较低， 而且面积越大， 相对与现有技术的成本优势就越突出。
2、 由于电磁感应式阵列天线作为识别感应器件， 因此其识别精度高， 能 够准确地通过笔触或手触输入鼠标信息或笔迹信息。
3、 信号产生是通过位于显示屏后面的电磁感应层产生， 作为触摸屏， 显 示屏的表面设有防护膜， 不易产生物理损伤， 因此使用寿命长。 附图说明
图 1为本发明一种实施例结构示意图；
图 2为本发明另一种实施例结构示意图；
图 3为本发明的识别电路结构示意图；
图 4为本发明电磁感应层结构示意图。 具体实施方式
下面结合附图和具体实施方式对本发明做进一步地详细说明。
参见图 1-4， 本发明为一种具有电磁感应触摸控制功能的显示屏， 它包括 平板显示屏本体以及触控感应层 4, 触控感应层 4输出接有识别电路， 显示屏 触控操作由电磁输入笔操控。 触控感应层 4设置在平板显示屏 3的后面， 其中 触控感应层 4由电磁感应发生层 41和底部支撑托层 42构成， 其中电磁感应发 生层 41 的基层为绝缘柔性隔膜 411， 隔膜 411表面印制有电磁感应天线阵列 412, 构成柔性隔膜式电磁感应发生层 41， 该层的输出接控制识别电路， 输入 笔带有电磁波发生装置。 识别电路可采用现有书写板识别电路中的任何一种， 因此本发明在此对识别电路不再赘述。 显示屏为等离子显示屏或液晶显示屏等 平板型显示屏。
平板显示屏本体包括正面壳体 1、 背面壳体 Ί 以及显示屏 3。 本发明的特 点是将触控感应层 4设置在显示屏 3的后面，电磁手写操控笔触压显示屏 3后， 触控感应层 4依然能够透过显示屏感应手写板触及的位置。
具体结构设计中， 触控感应层 4的面积与显示屏 3的面积一样大小。 触控 感应层 4的后面设有绝缘屏蔽隔离层 5， 绝缘屏蔽隔离层 5后设有识别电路层 6。 绝缘屏蔽隔离层 5 与触控感应 4、 识别电路层 6之间分别绝缘， 并且屏 蔽。 当然， 绝缘屏蔽隔离层 5、 识别电路层 6可以另外设置在显示屏或主机的 其他空间中。 而绝缘屏蔽隔离层 5、 识别电路层 6与触控感应层 4贴合设置可 集中感应整体装置。 为进一步保证屏蔽的效果， 绝缘屏蔽隔离层 5与识別电路 层 6之间设有一空间间隙。 当然， 如果屏蔽层 5与触控感应层 6之间保留空间 间隙， 已经具有绝缘效果， 该屏蔽层 5本体可不带有绝缘层物质。 屏蔽层 5用 于增强设备的抗干扰能力。
再有， 为提高显示屏 3表面的抗磨损等能力， 在显示屏 3的正面设有透明 的防护层或防护膜 2。
如图 2所示， 根据不同的需要， 例如显示屏 3的局部作为触摸输入或触摸 操作区域时， 触控感应层 4的面积可小于显示屏 3的面积， 设置在显示屏 3后 面的一侧， 也可设置在显示屏 3的两侧或四周。 当然， 触控感应层 4的面积也 可大于显示屏 3的面积， 这样整个显示屏 3以及显示屏 3的周边均可具有触控 的能力。
本发明显示屏 3隔离了操控笔与触控感应 4, 并不影响感应信号的产生 和传递。 如同手写板的绝缘保护膜隔离了手写操控笔与感应层一样， 工作机理 也同手写板的信号产生一样。 结合图 3 , 本发明在使用中， 感应的电磁信号源 是电磁操控笔， 电磁手写操控笔正常时不断地发射固定频率或数据电磁信号， 当笔尖被压触后， 电磁磁力线穿过电磁天线阵列， 对应电磁信号源中心及附近 的底层水平天线和顶层垂直天线感应该电磁信号， 通过识别电路接口传递给 CPU, CPU 计算比较感应天线的位置和电压强度、 频率信号变化， 判定电磁信 号源的位置和各种工作状态， 再将结果传递该 PC, 从而控制 PC完成各种动作 指令。 如文字或形状识别、 绘图和快捷键调用等。
具体地， 如图 4 所示， 电磁感应发生层 41 的基层为绝缘柔性隔膜 411 , 隔膜表面印制有电磁感应天线阵列 412 , 分别沿 X、 Y 轴分布、 "U" 形天线交 叉编排结构， 构成柔性隔膜式电磁感应发生层。 为降低成本电磁感应天线阵列 412为银浆或银浆与碳浆混合物印刷的电磁感应天线阵列。
为了提高识别精度， 电磁感应天线阵列 412为单面或双面柔性隔膜 411印 刷线路的结构， 也可为一片以上单面的柔性隔膜 411印刷线路叠置。 本发明能够广泛地应用于各种触摸控制设备上。 同时， 本发明的思想并不 局限于将电磁感应层与平板的显示屏相结合， 各种外形并非平面的等离子显示 屏、 液晶显示屏等非 CRT显示屏的后部均可结合电磁感应层， 而实现 成本的 触摸屏结构。
