具体实施方式
详细地参考本发明,附图示出了示例,所有附图中类似的参考数字指示类似的元件。下面的说明将使用与便携式电子设备相关的名称,然而本领域技术人员将认识到本发明可应用于各种便携式电子设备,例如蜂窝电话、移动电话、卫星电话、遥感勘测设备、个人数字助理(PDA)、以及其他便携的和手持的设备。
就如将在下面描述的,各种内容可以下载到电子设备,例如机票、电影票、演唱会门票、投注单,等等,所述内容包含可以由光学扫描器(例如条形码阅读器)读取的光学可扫描的标记(例如条形码)。在本发明的一个方面中,便携式电子设备可以包括多个不同类型的显示器,其中一个包括用于显示条形码的电子纸显示器。
图1图示了根据本发明的一方面的网络系统10的一个实施例的框图。在这个图示的实施例中,多个便携式电子设备20可以可操作地连接到通信网络30,例如蜂窝电话网络、全球网络(例如英特网)或其他合适的网络,用于与多个实体40(例如航空公司、售票公司等等)进行通信。在便携式电子设备20与网络30之间的通信优选无线通信。在网络30与多个实体40之间的通信可以是无线通信或非无线通信。
图2和图3图示了根据本发明的一方面的便携式电子设备20的一个实施例。示意性的便携式电子设备20可以包括具有前表面32(图1)、侧表面34、以及后表面36(图2)的外壳30。
参考图2,便携式电子设备20可以进一步包括第一显示屏40,例如背光式LED或LCD显示器,以及分离的第二辅助显示屏50,例如用于显示光学可扫描的标记(如条形码52)的电子纸显示器。电子纸显示器可以包括电子纸显示器、e纸(e-paper)显示器、电子墨水显示器、以及其他模仿在纸上出现普通墨水的显示器。不像传统的背光式平板显示器,电子纸显示器像普通的纸一样反射环境光,而不是发射它自己的光。显示器可以不使用电而无限期地保持文本和图像。显示器可以包括传统的电子纸技术,例如,一个或多个电极层和包括响应于电极层上的电荷而改变颜色的多个微珠(microscopic bead)的层。可以实现数据输入的键盘60也可以设置在外壳30的前侧32。相机70(图2)可以设置在外壳的背面。外壳12还可以支持多种组件,包括典型地位于主体后半部的电池。
如图4中所示的,便携式电子设备20可以包括,例如,计算单元或处理器22,一个或多个数据存储单元24(例如存储器或存储卡),以及一个或多个输入/输出设备26,例如第一显示器40、第二显示器50、键盘60、无线接收器80、和无线发送器90。
再次参考图2,显示器50可操作来显示条形码图像52,该条形码图像可操作为数据的光学机器可读表示。条形码可以通过改变平行线的宽度和间隔来表示数据,并可以称作线性的或1维的(1D)。如图5中所示的,显示器50可操作来显示条形码图像54,该条形码图像可操作为数据的光学机器可读表示。条形码图像54可以包括几何图案、长方形、点、六边形和其它2维(2D)的几何图案。上面描述的条形码可以以文件格式提供,例如便携网络图形(PNG)、联合图像专家组(JPG)、标记图像文件格式(TIFF)、位图(BMP)和图形交换格式(GIF)。可选地,数据可以是原始数据,这样的原始数据由便携式电子设备接收和处理以产生光学可扫描的标记(例如条形码),其显示在显示器50上。
如上所述,条形码显示在电子纸显示器50上,该电子纸显示器相比于在显示器40(如背光式显示器)上显示光学可扫描的标记有更高的分辨率和更低的眩光中的至少一个。通过这样做,条形码图像可以被条形码阅读器更容易和更精确地读取。
图6和图7图示了根据本发明的一方面的便携式电子设备120的另一个实施例。示意性的便携式电子设备120可以包括具有前表面132(图6)、侧表面134以及后表面136(图7)的外壳130。便携式电子设备120可以进一步包括设置在前表面上的第一显示屏140(图6),例如背光式LED或LCD触摸屏显示器,以及设置在后表面上的分离的第二显示屏150(图7),例如用于显示光学可扫描的标记(例如条形码)的电子纸显示器。显示屏140可以包括显示器142和设置在显示器上的触摸感应盖层(touch sensitive overlay)144。以这种方式,显示屏140操作为数据输入界面。显示屏140可以进一步包括实现数据输入的键盘148。相机170(图7)可以设置在外壳的背面。外壳130还可以支持多种组件,包括典型地位于主体后半部的电池。便携式电子设备120也可以包括与显示器140集成的图形用户界面,或“GUI”。GUI可以包括指针(pointer),其由操作者移动以在显示器上显示的各种显示的(有时称“虚拟的”)控制按钮之间选择。指针可以在网页浏览期间移动以选择文本或图标超链接控制按钮以高亮。控制按钮也可以被显示用于在各种菜单选项间选择。在一个示例中,控制按钮可以是一系列图标。选择一个图标根据选择的图标改变便携式电子设备120的操作模式。在一些实施例中,便携式电子设备120可以包括实现指针移动的指针控制器。指针控制器可以由箭头导航矩阵、跟踪球或操纵杆提供。在进一步的实施例中,GUI包括“虚拟的”键盘,因此消除了对额外硬件的需要。便携式电子设备120可以包括,例如,计算单元或处理器,一个或多个数据存储单元,例如存储器或存储卡,以及一个或多个输入/输出设备,例如第一显示器、第二显示器、键盘、无线接收器和无线发送器。
图8图示了根据本发明的一方面的便携式电子设备220的另一个实施例。示意性的便携式电子设备220可以包括具有前表面、侧表面和后表面(没有示出)的外壳230以及在上文的便携式电子设备中描述的组件。便携式电子设备220可以进一步包括显示屏210,其可以被形成或制造来包括第一显示屏240(例如背光式LED或LCD触摸屏显示器)和用于显示光学可扫描的标记(例如条形码)的分离的第二辅助显示屏250(例如电子纸显示器)。
如在图9中所示的,显示屏210可以包括包含第一显示屏240的第一部分以及包含第二显示屏250的第二部分,该第一显示屏可以包括传统LED或LCD技术,例如背光式触摸屏显示器242和触摸感应盖层244,该第二显示屏可以包括传统电子纸技术,例如,一个或多个电极层252和包括响应于电极层252上的电荷而改变颜色的多个微珠的层254。
图10图示了电子售票方法300,其大体上包括在310购买票,例如活动或机票。例如,票可以通过售票处、旅行社代理人、或网站购买。付款可以使用信用卡或借记卡而传统的完成。
在320,与购买的票相关的包括光学可扫描的标记的数据在包括第一显示器和第二电子纸显示器的便携式电子设备中被可操作的发送或从通信网络无线接收。数据也可以包括票的号码、活动、日期、开始时间、座位号等等。票的数据也可以包括购买者的移动电话号码或email地址,其也可以存储在与出售者(如实体40(图1))相关的数据库中。
在330,例如在活动时或在机场登记时,光学可扫描的标记可以显示在便携式电子设备的电子纸显示器上,以及在340,通过光学扫描器400(例如连接到终端410的手持扫描器)光学读取,如图11所示。各种内容可以下载到便携式电子设备,例如电影票、机票、演唱会门票、投注单,等等,所述内容包含可以由条形码阅读器读取的条形码。指示条形码在哪里的标签可以加到内容中,并且随后条形码符号(label)可以基于标签从原始的内容中分离,使得仅仅条形码显示在电子纸显示器上,让扫描器或条形码阅读器容易的读取。
例如,在便携式电子设备中的处理器可以从与电子票相关的数据中提取光学可扫描的标记,并且在电子纸显示器上显示与电子票相关的光学可扫描的标记。电子票的提供者可以提供标签或其他标记,由在便携式电子设备中的处理器使用以识别和提取条形码用于显示。可选地,没有标签或其他标记,处理器可操作来识别用于条形码的典型的文件格式,并提取文件以及可选择地显示文件和条形码在电子纸显示器上,而不是,例如背光式彩色显示器上。此外,数据可以是原始数据,以及这样的原始数据,其由便携式电子设备接收和处理以产生在电子纸显示器上显示的光学可扫描的标记(例如条形码)。将意识到,用于例如由出售者配置电子票的其他方式,以及用于提取和在辅助的电子纸显示器上显示条形码的方式可以被适当地使用。
再次参考图11,终端410可以是个人电脑,或其他合适的设备。条形码可以通过匹配来自扫描的条形码的条形码与存储的票的条形码和/或存储在终端的数据库中的其他信息来可操作地验证。在其他实施例中,手持扫描器可以通过网络30无线连接(例如,蓝牙或WiFi)到终端。例如,光学扫描器400可以使用包括光源、镜头、把光脉冲转换成电子数据的光传感器、以及分析由传感器提供的条形码图像数据并发送条形码内容的解码器电路的条形码阅读器或条形码扫描器,和/或认可扫描器的输出端口。条形码扫描器可以使用激光光束作为光源用于读取,例如,1维条形码。光电二极管用于测量从条形码反射回的光的强度。对于2维条形码,CCD(电荷耦合器件)和CMOS(互补金属氧化物半导体)阅读器可以被使用,其使用在阅读器头中排成行的成百上千个微小的光传感器的阵列。每个传感器测量正在它前面的光的强度。在阅读器中产生用于验证条形码的条形码的电压图案。可以使用环境光或阅读器可以使用光源。此外,光学扫描器400可以使用由wang等申请的公开号为2010/0078477,名称为“Method And Apparatus For Operating Indicia Reading Terminal IncludingParameter Determination”(用于操作包括参数确定的标记读取终端的方法和装置)的美国专利申请中公开的扫描处理,该申请包括定位和解码光学可扫描的标记,这个申请的整个内容通过参考合并于此。
在上面的实施例中,第一显示器可以设置在外壳上的第一位置,第二辅助电子纸显示器可以设置在不同于第一位置并与第一位置隔开的第二位置。例如,在第一显示器和第二电子纸显示器的相邻边缘部分之间可以设置有空间或外壳的一部分。
在上面的实施例中,第二电子纸显示器可操作来显示光学可扫描的标记,与在第一显示器上显示光学可扫描的标记相比具有更低的反射系数、更高的分辨率以及更高的对比度中的至少一个。例如,第一显示器可以被提供有半透明层、玻璃层、或其他材料层(例如外保护层)。第二电子纸显示器可以提供有导致第二电子显示器相比于第一显示器具有更低的反射系数的层,如半透明层、玻璃层、或其他材料层(例如外保护层)。例如,第二电子纸显示器可以包括用于从第二电子纸显示器表面漫反射环境光的层。第二电子纸显示器相比于第一显示器可以有更低的例如来自背光或反射的眩光。此外,第一显示器可以导致大体上镜面反射,镜面反射中来自单一入射方向(射线)的光被反射到单一的出射方向,而第二电子纸显示器可以导致漫反射,其中入射光被沿大致宽范围的方向反射。
第二电子纸显示器可以显示可扫描的光学标记,其在每一维中相比于第一方向具有更高的分辨率或显示分辨率,例如不同像素的数量。第二电子纸显示器可以显示可扫描的光学标记,相比于第一显示器,所述可扫描的光学标记具有更高的对比度或视觉特性(例如,颜色和明亮度)差异,这使得可扫描的光学标记更加有别于背景。
从本发明,本领域技术人员将意识到用于显示条形码的电子纸显示器的使用克服了在传统的移动电话中使用的显示器的问题,传统的移动电话中使用的显示器有差的分辨率、明亮的表面反射、以及低光照度,使得从显示器读取条形码是困难的。例如,彩色OLED或LCD显示器有由三种颜色组成的像素,即红、绿和蓝。这些像素和颜色的结合降低了对比度或者显示器需要背光去提高对比度。通过在便携设备中除了标准的彩色OLED和LCD显示器外还使用次要的或辅助的电子纸显示器,这些问题可以被克服。电子纸显示器提供了高的对比度和低的眩光使得可以容易地和精确地读取条形码,其中条形码阅读器正常地操作(它会的),例如,读取规则的纸条形码符号时。
虽然根据多个特定的实施例描述了本发明,将意识到本发明的正确的精神和范围应该仅仅参照由本说明书支持的权利要求确定。进一步,虽然在此的多个例子中,其中系统和装置和方法被描述为有特定数量的元件,将意识到这样的系统,装置和方法可以被实现为具有比提到的特定数量元件更少的元件。又,虽然多个特定的实施例已经被描述,将意识到关于每个特定实施例的已经被描述的特征和方面可以用于其余每个特定描述的实施例。
