Description

具有字符输入功能的电子装置
【技术领域】
本发明涉及一种具有字符输入功能的电子装置,特别涉及一种有触摸感应装置的具有字符输入功能的电子装置。
【背景技术】
桌上型计算机、笔记本计算机等电子设备用键盘完成字符输入功能。便携式电子装置因为其体积的限制,输入装置不能做得很大,而随着手机、PDA、电子书等产品的发展,以及如短信、电子邮件、记事本等功能在便携式电子装置上的应用,在便携式电子装置上输入文字已经成为一种重要的功能。现有的解决方案是在便携式电子装置上设计一个键盘,和现有的全尺寸键盘相比,按键的尺寸缩小,在一个按键上集成有数个字符,这即不方便手指操作,往往也需要操作数次才能输入一个字符。也可以只缩小按键的尺寸而不在一个按键上集成数个字符,这对便携式电子装置的尺寸或按键的数目都会造成限制。
电子设备中广泛使用触摸感应装置完成输入功能,其一般用来移动光标或者选取菜单项等。如果用软件实现一个虚拟键盘并将其显示在电子设备的显示屏上,然后用触摸感应装置来选取键盘中的字符,可以实现对字符的输入。而实现字符输入,该触摸感应装置可为如下方式:一种为在该显示屏上覆盖一层感应触摸层形成感应触摸屏,直接触摸显示屏相应位置输入所需的字符;另一种为虚拟键盘(即显示屏)和触摸感应装置分开,由操作触摸感应装置使光标移到欲选择的字符并选中。
在利用感应触摸屏方式中,覆盖一层感应触摸层不但增加产品的成本,而且很容易弄脏、刮伤,甚至弄坏显示屏。而,在显示屏和触摸感应装置分开的方式中,使用者眼睛看虚拟键盘,手操作触摸感应装置使光标移到欲选择的字符并选中它,眼和手的工作不能结合,从而降低效率。而且,上述两种方式由于虚拟键盘显示于显示屏上,占用一定面积的显示屏,相对应地,内容显示的面积就被减小了;另外,在显示屏显示该虚拟键盘,也增加了实现的难度。
【发明内容】
有鉴于此,本发明的目的是提供一具有字符输入功能的电子装置,该电子装置于显示屏壳体上分布有触摸感应装置用于字符输入,方便字符输入。
所述具有字符输入功能的电子装置,该电子装置包括一显示屏和于显示屏壳体上分布的触摸感应装置,在该触摸感应装置上有多个字符以及和该多个字符分别对应的触摸感应单元,触摸其中一触摸感应单元,输入和该触摸感应单元对应的字符。
本发明可以在电子装置中省略键盘,使电子装置的部件更简洁,显示屏可以做的更大,方便输入。
【附图说明】
图1是具有字符输入功能的电子装置的外观图;
图2是触摸感应装置的感应信号处理电路图;
图3是具有字符输入功能的电子装置的操作示意图。
【具体实施方式】
参考图1,是具有字符输入功能的电子装置的外观图。电子装置10可为手机、MP3、PDA、电子书等,该电子装置10包括一显示屏12和于显示屏壳体上部署的一触摸感应装置11,该触摸感应装置11包括有多个触摸感应单元,每一触摸感应单元上有一字符之标示,该字符可以字母、数字或非字母数字字符。在本发明的该触摸感应装置11上标示有A-Z共26个字母,0-9共10个数字和非字母数字字符,该触摸感应装置11提供字符数个的触摸感应单元,该字符数个的触摸感应单元和该字母、数字和非字母数字字符一一对应。
参考图2,是触摸感应单元的感应信号处理电路图,必须说明的是,本实施例所描述的只是触摸感应装置的一种实现形式,其可以有其它形式。
在该电子装置10上有触摸感应装置11,该触摸感应装置包括多个触摸感应单元,一触摸感应单元对应一矩阵坐标及一感应信号处理电路23。其中,该矩阵坐标用于标识该触摸感应单元在触摸感应单元矩阵中的位置;该感应信号处理电路23用于当使用者触摸该触摸感应单元时产生一信号。
该感应信号处理电路23包括一天线210、一钳位电路211、一侦测器212、一回馈线213及一接地线214。其中钳位电路211一端与该天线210相连,另一端与该侦测器212的输入端相连。该侦测器212的输出端与一处理单元20相连,同时连接该回馈线213。该处理单元20与该多个触摸感应单元连接。该回馈线213与该天线210构成一正回授电路,以提高感应单元的准确度。该接地线214用于隔离各个触摸感应单元,以免其产生相互干扰。其中,天线210对应于触摸感应单元,用于接收人体的交流电信号(一般人体具有50-60HZ的交流电信号)。该钳位电路211用于控制所接收的交流电信号电压的大小,以免所接收的电信号电压过大而击穿该侦测器212,且可调节该天线210的灵敏度,其包括一二极管216及一电容217。其中该二极管216的正极与该天线210相连,负极接地,当上述交流电信号流经该钳位电路211时,该二极管216可削减部分交流电信号电压,且可过滤掉输入端的高压静电达到保护电路的目的;该电容217一端与该侦测器212的输入端相连,另一端接地,主要用来减弱部分交流电信号,以便控制输入灵敏度的高低。该侦测器212用于将上述接收的交流电信号转变为数字信号送给该处理单元20进行处理从而执行相应功能,其具有高输入阻抗容易感应交流电信号并导通,即只要有一定的信号电压输入该侦测器212输入端,其输出均以高低电平随时间不断变换的脉冲形式输出。
由于该处理单元20连接有触摸感应单元,那么该处理单元20可周期性地扫描所述触摸感应单元矩阵内所产生的感应信号,并根据矩阵坐标识别出当前正被触摸的触摸感应单元。
参考图3,是具有字符输入功能的电子装置的操作示意图。当用户欲输入某字符时,用户可以触摸触摸感应装置11上显示的该字符,从而触摸和该字符对应的触摸感应单元,从而输入该字符。例如,当用户欲输入字符A时,用户即可触摸触摸感应装置11上显示的字符A,即可输入字符A。
在本发明中,触摸感应装置的形状和分布、字符显示区域的分布和字符显示的方式可以有其它形式,不限于本实施例所揭露的方式。
