Description

一种笔记本电脑 技术领域：
本发明涉及计算机技术领域， 尤其是涉及笔记本电脑技术领域。
背景技术：
见附图 1所示:常见的笔记本电脑主要由装设有键盘 03以及触控板 04的基 座 01以及设有液晶显示屏 05的上盖 02组成。
一般的笔记本电脑上的触控板， 其灵敏度与易用性取决于 IC solution的选 择， 若使用较低阶的 IC solution, 则零敏度较差， 并只能用较小面积的触控板 05， 因此光标的位移速度较慢， 使用者的食指必须在触控板上滑动多次才达到 目标区。 而高阶的笔记本电脑使用面积较大的触控板， 并用两颗高阶的 IC来解 决上述问题， 这些高阶的笔记本电脑的触控板灵敏度较高， 但成本高出很多； 另外， 虽然这种触控板其光标的移动速度与普通的光电鼠标差异不大， 但是因 为手指操作方向不一定与使用者脑部的指示完全一致， 故也需要滑动两三次食 指才能到达目标， 使用上仍存在不便之处。
事实上现有一般的触控板控制芯片皆为可编程***单芯片 PSOC, —般透 过软件的编写， 依据手指的位置与移动， 可作为以下数种用途：
1. 光标滑动用途， 如同一般鼠标；
2. 手写文字输入用途；
3. 定位用途； 一般是用在附设于液晶显示器表面的透明触摸屏， 而笔记本 计算机一般不作此用途， 但因为屏幕面积大而触控板面积小， 故食指的轻微移 动， 就可能造成光标移动的距离超过目标， 对于文字处理以及拉菜单较不合适;
4. 输入文字与功能按键用途， 许多触控板利用开关切换可作为两种用途， 一般是液晶显示器表面的透明触摸屏作为定位用途， 但也可切换为手写文字输 入用途；
还有笔记本计算机触控板除了作为光标滑动主用途之外， 亦作为输入文字 与功能按键用途， 或是手写文字输入用途。
上述方式都没有解决光标滑动用途须要将手指滑动两三次食指才能到达目 标的问题， 若能结合定位用途与光标滑动用途， 则可解决此问题。
发明内容：
本发明的目的在于针对现有技术存在的不足之处而提供一种新的笔记本电 脑， 它具有光标移动速度快且成本较低的优点。
为实现上述目的， 本发明的一种笔记本电脑包括基座以及与基座铰接的上 盖， 其中， 基座上设有键盘以及触控板， 上盖上则设有液晶显示屏， 所述的触 控板内设有侦测手指在触控板盘面上的运动位移量为停留状态或滑动状态的感 应装置， 通过软件使光标在定位模式和光标滑动模式这两种运动模式中切换； 在定位模式的状况， 根据其在触控板上点触的位置， 迅速将光标位移到显示屏 上的相应位置定位； 在光标滑动模式的状况， 则光标在显示屏上相应地滑动。
所述光标运动模式的切换方法之一为:触控板首先侦测手指为停留状态还是 运动状态， 如果使用者的手指点击触控板并在设定的时间内未超过一定的位移 量， 随后垂直离开， 光标切换为定位模式， 并根据其在触控板上的点触位置， 迅 速位移到显示屏上的相应位置定位； 如果使用者的手指点击触控板并在设定的 时间位移量超过一定数值， 则光标切换为光标滑动模式， 并在显示屏上相应地 滑动。
若手指点触在触控板面停留一段短时间未超过一定的位移量，且未离开触控 板面， 进入定位模式直接位移光标， 之后手指在触控板面上滑动， 则软件以定 位模式并根据各个时间段侦测到的手指位置， 将屏幕上的光标相对应于手指的 移动调整位置。
当手指点触进入定位模式之下， 软件进入一个很短的特定时间的等待期。若 在此等待期间内手指未回到触控板面， 则进入定位模式直接位移光标； 若在 此等待期间内手指再次点击触控板面， 则进入双击模式， 触控板芯片对计算机 发出两次鼠标左键讯号， 之后复位回到起始状态。
所述光标运动模式的切换方法之二为：当手指接触触控板时， 首先以光标滑 动模式运作， 若手指有位移则光标在显示屏上相应地滑动 ， 若手指无位移则 自然为停止状态； 当手指离开触控板时感应电流停止， 则软件依据开始和终的 位置算计位移量， 判断为停留状态还是运动状态，若超过一定的位移量， 则为运 动状态， 停止运算； 若未超过一定的位移量， 则光标切换为定位模式， 并根据 其在触控板上的停留点位置迅速位移到显示屏上的相应位置定位； 然后再次切 换， 回到光标滑动模式等待下次的操作。
触控板上印刷有网格， 且触控板的长宽比例与显示屏的长宽比例相同。 本发明采用目前通用的触控板控制芯片，不用设计新的控制芯片，只需修改 软件， 即可立即应用到所有的笔记本电脑； 此外， 本发明可以使用较低阶的 IC solution以及较小面积的触控板， 成本也较低。
附图说明：
下面结合附图对本发明做进一步的说明：
附图 1为现有的笔记本电脑的结构示意图；
附图 2为本发明的结构示意图； 附图 3为本发明的第一种运算方式的 软件流程图。
附图 3为本发明的第二种运算方式的软件流程图。
具体实施方式：
以下所述仅为体现本发明原理的较佳实施例，并不因此而限定本发明的保护 范围。
见附图 2所示： 它包括基座 10以及与基座 10铰接的上盖 20， 其中， 基座 10上设有键盘 30以及触控板 40， 上盖 20上则设有液晶显示屏 50， 触控板 40 内设有侦测手指在触控板 40盘面上为停留状态或滑动状态的感应装置， 通过软 件使光标在定位模式和光标滑动模式这两种运动模式中切换。 另外， 触控板 40 上印刷有网格， 且触控板 40的长宽比例与显示屏 50的长宽比例相同， 以方便 使用者快速进行光标定位。
在定位模式操作时， 当使用者看到液晶显示屏 50上的目标后， 即可很容易 地判断将手指轻触到触控板 40上的相应区域， 光标随即迅速位移到显示屏 50 上对应触控板 40上手指坐标的位置， 因为目视判断与手指动作会有误差， 故只 能尽量接近目标附近。 之后， 光标切换为光标滑动模式后， 只要食指滑动使光 标进行些许位移， 即可准确到达目标， 非常快捷方便。
本发明的光标切换方法可有两种运作方式：
见图 3所示： 第一种切换方法的软件流程如下：
当手指轻触触控板 40表面产生静电感应， 则触控芯片侦测到静电流并启动 运算程序， 首先以光标滑动模式运作；
软件侦测手指位置， 每隔一定时间（0.005~0.05秒之间选一个适合的时间间 隔）， 软件侦测一次手指位置的坐标 （Xl、 X2、 X3、 X4…… Xf， Yl、 Y2、 Υ3、 Y4…… Yf )， 若手指有位移则光标在显示屏上相应地滑动， 若无位移则自然为停 止状态。
当手指离开触控板 40时感应电流停止，则软件依据开始和终的位置 XI - Xf， Y1 - Yf算计位移量， 判断为停留状态还是运动状态， 若超过一定的位移量， 则 为运动状态， 停止运算。
若未超过一定的位移量，则光标切换为定位模式，并根据其在触控板上的停 留点位置迅速位移到显示屏上的相应位置定位， 然后再次切换， 回到光标滑动 模式等待下次的操作。
当手指轻触触控板 40表面产生静电感应， 则触控芯片侦测到静电流并启动 运算程序；
接着， 软件侦测手指位置， 判断手指是停留还是滑动， 每隔一定时间 （在 0.005-0.01秒之间选一个合适的时间间隔），软件侦测一次手指位置的坐标（XI、 X2、 X3、 X4、 … Xt , Υ1、 Υ2、 Υ3、 Υ4、 … Yt )。 然后比较第 1个时间段和第 t 个时间段之间是否产生位移， 第 t个时
间段可依需要设定为 2、 3、 4、 …。
软件侦测得到手指在 t个时间段的坐标 XI、 X2、 X3、 X4、 ··· ··· X t ; Yl、
Y2、 Υ3、 Υ4 Yt后， 软件对第 1和第 t个时间段所侦测的手指坐标进行位 置计算， 比较 Xt-Xl以及 Yt-Yl是否超过设定的位移量 D (0.5~2mm)， 并以此 来确定光标切换为定位模式或是光标滑动模式。
如果 Xt-Xl >D且或 Yt-Y1>D，则为光标滑动模式，启动光标滑动运算程序； 如果 Xt-Xl < 0且 Yt-Yl < D， 则为定位模式， 启动定位运算程序， 将原本停留 的光标， 位移到屏幕上相对应于触控板手指坐标的位置。 当手指离开触控板 40 表面后静电电流停止， 触控芯片 40侦测不到静电流， 从而停止运算程序。
此流程还可以有一种延伸操作模式：若手指点触在触控板面停留一段短时间 未超过一定的位移量， 且未离开触控板面， 进入定位模式直接位移光标， 之后 使用者在触控板面上移动指位置， 则屏幕上光标以定位模式相对应调整位置。
此方式适合在一些不需精细操作的状况， 例如网页点选或桌面找文件， 手 指点触短暂停留不离开并进入定位模式后， 只要不离开直接在盘面上轻微滑动， 可快速到达目标， 在一些须精细操作的状况， 将手指移开再回到触控板面滑动， 即可到达目标。
见图 4所示： 第二种切换方法的软件流程如下：
当手指轻触触控板 40表面产生静电感应， 则触控芯片侦测到静电流并启动 运算程序；
接着， 软件侦测手指位置， 判断手指是停留还是滑动， 每隔一定时间 （在 0.005-0.01秒之间选一个合适的时间间隔），软件侦测一次手指位置的坐标（XI、 X2、 X3、 X4、 … Xt, Υ1、 Υ2、 Υ3、 Υ4、 … Yt )。 然后比较第 1个时间段和第 t 个时间段之间是否产生位移， 第 t个时
间段可依需要设定为 2、 3、 4、 …。
软件侦测得到手指在 t个时间段的坐标 XI、 X2、 X3、 X4、 ······ X t; Yl、
Y2、 Υ3、 Υ4 Yt后， 软件对第 1和第 t个时间段所侦测的手指坐标进行位 置计算， 比较 Xt-Xl以及 Yt-Yl是否超过设定的
位移量 D (0.5~2mm)， 并以此来确定光标切换为定位模式或是光标滑动模式。
如果 Xt-Xl >D且或 Yt-Y1>D，则为光标滑动模式，启动光标滑动运算程序； 如果 Xt-Xl < 0且 Yt-Yl < D， 则为定位模式， 启动定位运算程序， 将原本停留 的光标， 位移到屏幕上相对应于触控板手指坐标的位置。 当手指离开触控板 40 表面后静电电流停止， 触控芯片 40侦测不到静电流， 从而停止运算程序。

5. 根据权利要求 1所述的笔记本电脑， 其特征在于： 所述光标运动模式的 切换方法为： 当手指接触触控板时， 首先以光标滑动模式运作， 若手指有位移 则光标在显示屏上相应地滑动， 若手指无位移则自然为停止状态； 当手指离开 触控板时感应电流停止， 则软件依据开始和终的位置算计位移量， 判断为停留 状态还是运动状态， 若超过一定的位移量， 则为运动状态， 停止运算； 若未超 过一定的位移量， 则光标切换为定位模式， 并根据其在触控板上的停留点位置 迅速位移到显示屏上的相应位置定位； 然后再次切换， 回到光标滑动模式等待 下次的操作。
6. 根据权利要求 1~5中任一项所述的笔记本电脑， 其特征在于： 触控板上 印刷有网格， 且触控板的长宽比例与显示屏的长宽比例相同。
