Description

电子装置
技术领域
本发明涉及一种电子装置。
背景技术
目前电子装置(例如是手机)的控制界面大多是触控显示器，而触控显示器可分为电阻式触控、电容式触控以及波动式触控。而电容式触控相较于其他触控方式具有触控反应速度快、高可靠度以及高清晰度的优势，因此，目前的电子装置大多数采用电容式触控显示器。此外，在指纹识别器上也是采用电容式的指纹识别器。
然而，电容式触控显示器与电容式指纹识别器因其原理为感应表层电容，使得在一些特殊环境下而有控制困难、触控精准度不佳或是无法使用等情况发生，例如在水下的环境，会因为水流而让触控显示器与电容式指纹识别器的系统误以为是有触控发生而使得使用者无法控制电子装置。因此，如何开发在特殊环境下仍能控制电子装置的系统与方法，为电子装置所亟欲解决的问题之一。
发明内容
本发明提出一种电子装置，其提供另一种控制显示器所显示的物件的方案，能够适用于各种使用环境。
本发明实施例提供一种电子装置，包括显示器、波传感器以及控制器。显示器具有相对的显示侧与背侧，其中显示侧用以供手指触碰。波传感器配置于显示器的背侧，且用以感测手指的手指图像，其中波传感器的感测方向朝向显示器。控制器用以根据波传感器所感测到的手指图像的移动，来对应控制显示器所显示的物件的移动。
基于上述，在本发明实施例的电子装置，波传感器的感测方向朝向显示器，可以直接在显示器的显示侧感测手指的图像，因此，相较于现有的电子装置在背盖感测手指的图像，本发明实施例的电子装置对于使用者来说较为直觉。此外，控制器用以根据波传感器所感测到的手指图像的移动，来对应控制显示器所显示的物件的移动，即使在触控显示器的触控有控制困难的情况下，本发明实施例的电子装置仍可控制显示器所显示的物件的移动，因此，本发明实施例的电子装置能克服现有的电子装置在特殊环境下无法控制电子装置的问题。
为让本发明的上述特征和优点能更明显易懂，下文特举实施例，并配合附图作详细说明如下。

具体实施方式
图1示出为本发明的实施例的一种电子装置的示意图。请参照图1，在本实施例中，电子装置100包括显示器110、波传感器120以及控制器130。显示器110具有相对的显示侧111与背侧112，其中显示侧111用以供手指140触碰。波传感器120配置于显示器110的背侧112，且用以感测手指140的手指图像，其中波传感器120的感测方向朝向显示器110。控制器130用以根据波传感器120所感测到的手指图像的移动，来对应控制显示器110所显示的物件的移动。此处的手指图像可以是较低解析度的而可以显现出手指触碰时的大概轮廓的图像，或者也可以是较高解析度而可以清楚显现手指的指纹的图像。
在本实施例中，电子装置100可为手机、平板电脑、笔记本电脑、个人数字助理(PDA)、数码相机，或是其他具有触控功能的电子装置。
在本实施例中，电子装置100的防水等级为IP68以上。此外，波传感器所感测到的手指图像的解析度落在500每英寸点数(Dots Per Inch，DPI)至1000每英寸点数(DPI)的范围内。
图4示出为本发明的电子装置的控制器根据手指图像的移动或旋转来对应控制显示器所显示的物件的移动或旋转的示意图。请参照图4，在本实施例中，电子装置400的控制器除了用以根据波传感器120所感测到的手指图像的移动，来对应控制显示器110所显示的物件的移动之外，电子装置400的控制器也可根据手指图像的旋转来对应控制显示器110所显示的物件的旋转。但本发明不以此为限，电子装置400也可实现复杂的控制方式，具体来说，控制器也可根据手指图像的移动方向与大小以及旋转的方向与角度来对应控制显示器110所显示的物件的移动方向与大小以及旋转的方向与角度，其中使用者可设定显示器110所显示的物件所对应的移动量与旋转量，例如是，手指沿一个方向移动并旋转，而显示器110所显示的物件也因此沿所述方向移动并以手指的移动量的某个倍数在移动，而显示器110所显示的物件以相同于手指的旋转量在旋转。
以下将说明本发明的电子装置100的解锁方法与控制方法。
图2示出为解锁本发明的电子装置的流程图。请参照图2，本实施例的电子装置100的解锁方法，为当使用者开始使用电子装置100时(步骤S210)，例如是在电子装置100开机后，使用者按下电源键而使电子装置100进入步骤S210；或是电子装置100于开机后，只要是电子装置100是在锁定状态，则会维持在步骤S210，意思是，电子装置100会持续发出光波150或超音波(如图5的超音波550)来感测手指140触碰，或是电子装置100会每隔一段时间发出光波150或超音波(如图5的超音波550)来感测手指140触碰。
当电子装置100进入步骤S210后，控制器130判断波传感器120所感测到的手指图像是否为数据库中所存储的指纹(步骤S220)，若为是，则解锁电子装置100(步骤S230)，若为否，则不解锁电子装置100(步骤S240)。
值得一提的是，上述电子装置100的解锁方法，不需要使用太高的手指图像的解析度，只要能清楚地看到手指的指纹即可，例如是手指图像的解析度为500每英寸点数(DPI)，电子装置100即可有足够的解析度识别所感测到的手指图像是否符合数据库中所存储的指纹。再者，上述电子装置100的解锁方法更可包括手势解锁，具体来说，电子装置100的显示器110为触控显示器，且控制器130判断波传感器120所感测到的手指图像及触控显示器所感测到的手势是否为数据库中所存储的指纹与手势(对应于步骤S220)，若为是，则解锁电子装置100(步骤S230)，若为否，则不解锁电子装置100(步骤S240)。
接着说明本发明的电子装置100的控制方法。
图3示出为本发明的电子装置的控制方法的流程图。请参照图3，本实施例的电子装置100的控制方法，为当电子装置100不在锁定状态时，电子装置100的控制器130可进入感测手指图像的移动的模式(步骤S310)，例如是电子装置100的波传感器120感测到使用者的手指140持续触碰则进入步骤S310；或是电子装置100不在锁定状态时，也就是上述电子装置100解锁后(步骤S230)，电子装置100会直接进入步骤S310。
当电子装置100进入步骤S310后，控制器130判断刚触碰到显示器110且被波传感器120感测到的手指140的手指图像是否为数据库中所存储的指纹(步骤S320)，若为是，则控制器130继续感测手指图像的移动(步骤S330)，若为否，则锁定电子装置100(步骤S340)。此外，控制器130每隔特定时间判断被波传感器120感测到的手指140的手指图像是否为数据库中所存储的指纹(步骤S350)，若为是，则控制器130继续感测手指图像的移动(步骤S330)，若为否，则锁定电子装置100(步骤S340)。
值得一提的是，上述电子装置100的控制方法，为了能清楚地看到手指的手指图像移动，则需要使用较高的手指图像的解析度，例如是手指图像的解析度为1000每英寸点数(DPI)，而使电子装置100能精确地感测使用者手指的移动与旋转。因此，波传感器120可以具有适用于1000DPI的解析度，而在执行上述的电子装置100的控制方法时，控制器130将波传感器120切换至高解析度模式，但在执行上述电子装置100的解锁方法时，可将波传感器120切换至较低解析度的模式，只要能清楚地看到手指的指纹即可，例如适用于500DPI的解析度。再者，电子装置100的控制方法不以上述的步骤为限，亦可根据使用者的使用习惯而进一步增减控制步骤，例如是可增加控制步骤：控制器130依据手指140连续触碰显示器110，而对应地点选显示器110所显示的物件；或例如是可减去步骤S320。
基于上述，由于本发明实施例的电子装置，其波传感器的感测方向朝向显示器，可以直接在显示器的显示侧感测手指的图像，即为显示器下(Under Display)感测，因此，本发明实施例的电子装置对于使用者来说较为直觉。此外，控制器用以根据波传感器所感测到的手指图像的移动，来对应控制显示器所显示的物件的移动，且因为电子装置的防水等级为IP68以上，因此，即使在触控显示器的触控有控制困难的情况下，例如是水下使用电子装置，本发明实施例的电子装置仍可控制显示器所显示的物件的移动。再者，本发明实施例的电子装置的解锁方法不需要使用太高的手指图像的解析度即可有足够的解析度识别使用者的手指图像是否正确，因此，本发明实施例的电子装置可快速的解锁。而本发明实施例的电子装置的控制方法使用较高的手指图像的解析度，因此能精确的感测使用者手指的移动与旋转。
以下将说明本发明另一实施例的一种电子装置。
图5示出为本发明的另一实施例的一种电子装置的示意图。请同时参照图1与图5，在本实施例中，电子装置的波传感器120为光学式指纹传感器或是超音波式指纹传感器。其中波传感器120所感测到的手指图像是由显示器110所发出的光波150经由手指反射而产生的图像，或者是，波传感器120所感测到的手指图像是由电子装置100所发出的光波150或超音波550经由手指反射而产生的图像。
举例来说，波传感器120为图1的光学式指纹传感器，其中光学式指纹传感器感测可见光，且波传感器120所感测到的手指图像是由显示器110所发出的(可见光)光波经由手指反射而产生的图像；或例如是传感器120为图5的光学式指纹传感器，其中光学式指纹传感器感测非可见光(例如红外光)，电子装置500还包括波发射器510，且波传感器120所感测到的手指图像是由波发射器510所发出的光波(非可见光)150经由手指反射而产生的图像；或例如是传感器120为图5的超音波式指纹传感器，其中波传感器120所感测到的手指图像是由波发射器510所发出的超音波550经由手指反射而产生的图像。
基于上述，由于本发明实施例的电子装置，其波传感器为光学式指纹传感器，且波传感器所感测到的手指图像是由显示器或电子装置所发出的光波经由手指反射而产生的图像，因此具有较低的成本。此外，本发明实施例的电子装置，其波传感器为超音波式指纹传感器，且波传感器所感测到的手指图像是由电子装置所发出的超音波经由手指反射而产生的图像，因此具有较高的穿透距离，可以适用于较厚的显示器。
上述的控制器130例如是包括中央处理单元(central processing unit,CPU)、微处理器(microprocessor)、数字信号处理器(digital signal processor,DSP)、可程序化控制器、可程序化逻辑装置(programmable logic device,PLD)或其他类似装置或这些装置的组合，本发明并不加以限制。此外，在实施例中，控制器130的各功能可被实作为多个程序码。这些程序码会被存储在一个存储器中，由控制器130来执行这些程序码。或者，在实施例中，控制器130的各功能可被实作为一或多个电路。本发明并不限制用软件或硬件的方式来实作控制器130的各功能。
综上所述，由于本发明实施例的电子装置，其波传感器的感测方向朝向显示器，可以直接在显示器的显示侧感测手指的手指图像，即为显示器下(Under Display)感测，因此，本发明实施例的电子装置对于使用者来说较为直觉。此外，控制器用以根据波传感器所感测到的手指图像的移动，来对应控制显示器所显示的物件的移动，且因为电子装置的防水等级为IP68以上，因此，即使在触控显示器的触控有控制困难的情况下，例如是水下使用电子装置，本发明实施例的电子装置仍可控制显示器所显示的物件的移动。再者，本发明实施例的电子装置的解锁方法不需要使用太高的手指图像的解析度即可有足够的解析度识别使用者的手指图像是否正确，因此，本发明实施例的电子装置可快速的解锁。而本发明实施例的电子装置的控制方法使用较高的手指图像的解析度，因此能精确的感测使用者手指的移动与旋转。
而且，由于本发明实施例的电子装置，其波传感器为光学式指纹传感器，且波传感器所感测到的手指图像是由显示器或电子装置所发出的光波经由手指反射而产生的图像，因此具有较低的成本。此外，本发明实施例的电子装置，其波传感器为超音波式指纹传感器，且波传感器所感测到的手指图像是由电子装置所发出的超音波经由手指反射而产生的图像，因此具有较高的穿透距离，可以适用于较厚的显示器。
虽然本发明已以实施例揭示如上，然其并非用以限定本发明，任何所属技术领域中技术人员，在不脱离本发明的精神和范围内，当可作些许的更改与润饰，故本发明的保护范围当视权利要求所界定的为准。
