[0019] 图 8是实施例 4的电子产品的结构示意图。
[0020] 具体实施方式
[0021] 依据本发明的电子产品包括显示面和输入面， 显示面和输入面在位于其边缘的 旋转轴线处彼此连接， 并能够绕该旋转轴线旋转， 当显示面和输入面之间的夹 角为锐角吋， 显示面和输入面彼此相对。 本文所称"旋转轴线"是指几何意义上的 "直线"， 在具体实施方式中， 既可以呈现为实体的机械转轴， 也可以呈现为柔性 材料折叠所形成的边缘。
[0022] 依据本发明的电子产品的显示面由复合显示装置提供显示功能的一面充当， 而 输入面则由感光输入装置提供输入功能的一面充当。 复合显示装置和感光输入 装置可采用各种可用的连接方式可折叠地彼此连接。 例如， 二者之间的电路连 接和机械连接均采用可分离的插拔式连接方式， 或者， 均采用柔性连接方式。 又如， 复合显示装置的部分与感光输入装置的部分共同形成为一个整体的柔性 材料层， 该柔性材料层能够沿旋转轴线折叠， 柔性材料层具体可以由柔性显示 屏或柔性触摸屏充当。 [0023] 参考图 1， 示出了一种可分离的电路和机械连接结构。 其中包括轴套 D31， 轴杆 D32, 电路接口的插头 D33， 电路接口的插座 D34。 轴套可固定在例如输入装置 的边缘。 轴杆相应固定在显示装置的边缘， 其尺寸与轴套内径相匹配。 通过轴 套的弹性形变将轴杆卡入到轴套中， 二者紧密贴合并可在一定的摩擦力下相对 旋转， 此吋轴杆的中轴 DD即为"旋转轴线"。 电路的信号线 D35从轴杆 D32内部穿 过， 再通过插头 D33与插座 D34连接， 以实现两个装置之间的电路连接。
[0024] 显示面和输入面之间的转动角度范围可以根据产品的需要来设计， 例如可以是 0-360度的范围， 对于移动电脑等应用， 也可以是 0-130度的范围。 在需要大的旋 转角度的情况下， 轴套 D31还可以进一步通过其两端的轴杆 D311以可转动的方式 固定在装置边缘的另一个轴套 （未图示） 内， 即以叠加嵌套的方式来实现大角 度的旋转。
[0025] 采用这种可分离的插拔式连接方式使得复合显示装置和感光输入装置能够任意 替换或重复使用。 尤其是在对机械接口和电路接口进行标准化以后， 不同的电 子产品之间能够重复利用同一部件， 有利于减少浪费。
[0026] 此外， 还可以根据生命周期的长短对电子产品上的功能模块进行分类， 将生命 周期接近的模块设置在同一装置上， 以便于在损坏或需要更新吋进行整体替换 。 例如， 可以将生命周期较短的模块设置在输入装置上， 而将生命周期较长的 模块设置在显示装置上。
[0027] 作为一种优选的实施方式， 可进一步包括角度锁定结构， 用于将显示面相对于 输入面锁定在任意角度； 例如可采用自锁式的转轴连接件， 通过轴杆与轴套之 间的摩擦来进行自锁， 或者也可以通过插入插销等方式来进行角度锁定。
[0028]
[0029] 本发明中的复合显示装置融合了发光和感光两种基本功能， 其基本结构包括显 示像素阵列， 感光像素面和周边电路。
[0030] 显示像素阵列由多个显示像素组成， 形成为显示装置的显示面， 通过发光实现 显示装置的显示功能。 显示像素阵列的实现可采用各种可行的阵列发光技术， 例如发光二极管 （LED) 阵列， 有机发光二极管 （OLED) 阵列等。 OLED中的 有源矩阵有机发光二极管 （AMOLED) 是一种优秀的选择。 [0031] 感光像素面由至少一个感光像素组成。 所称感光像素可由各种类型的感光器件 形成， 其状态与入射的外部光线的光强相对应， 只要其某种可检测的状态能够 根据不同的入射光强产生相应的变化即可。 例如可选择感光 （或光伏） 二极管 、 感光电阻等。 根据感光器件的不同特性， 其状态变化的方式也可以不同， 例 如可以是电阻值的变化， 也可以是电压值的变化等。
[0032] 周边电路包括显示控制电路和感光控制电路。 显示控制电路用于驱动显示像素 发光， 感光控制电路用于读取感光像素感应的电荷或电压。 这两个控制电路可 以根据所匹配的像素阵列的具体类型进行设计， 可以是彼此独立的， 也可以根 据功能和结构的相似性， 共享部分线路或元件。
[0033] 根据所选择的感光像素的具体特性的差异， 其可以用于实现各种不同的功能。
包括但不限于：
[0034] 功能一， 用于供电。 在这种情况下， 感光像素可采用光伏器件来充当， 感光控 制电路读取的感光像素感应的电荷或电压用于作为电能储存或使用。 本文中的" 光伏器件"代表各种可能的用于供电的光电转换器件， 包括但不限于， 多晶硅光 伏板、 单晶硅光伏板、 非晶硅光伏板、 III-V半导体光伏板、 铜铟镓硒 （CIGS) 光伏板、 钙钛光伏板、 光伏薄膜等， 以下不再赘述。 通过感光像素实现的供电 功能有利于增加电子产品的续航吋间。
[0035] 功能二， 用于成像。 这种情况下， 感光像素可采用常见的感光器件制作方式来 获得， 感光控制电路读取的感光像素感应的电荷或电压用于成像。 所称成像的 功能， 例如， 可用于输入指纹、 掌纹或眼睛虹膜等， 有利于丰富电子产品的功 能并提高其使用的安全性。
[0036] 功能三， 用于输入。 一个或多个感光像素形成为一个输入元件， 感光控制电路 还用于重置各个输入元件所对应的感光像素， 根据重置后读取的与各个输入元 件所对应的感光像素感应的电荷或电压， 输出表示相应的输入元件被遮挡或不 被遮挡的键信号 （key signal) 。
[0037] 以上三种功能可以分别实现也可以同吋实现。 例如， 用于供电的感光像素也可 以切换为用于提供输入功能， 反之亦然， 只需要感光控制电路改变对所读取的 电荷或电压的使用方式即可。 这样， 感光像素既能够在用户需要吋用于实现输 入， 还能够在空闲吋进行光能的转换和利用， 进一步丰富复合显示装置的功能
[0038] 在复合显示装置中， 显示像素阵列与感光像素可采用重叠或交错的方式进行布 置。 具体地， 沿垂直于显示装置的显示面的方向， 至少部分显示像素和感光像 素彼此上下重叠地布置， 或者， 在同一个平面上彼此前后、 左右交错地布置； 且显示像素发光所覆盖的区域与感光像素感光所覆盖的区域， 至少部分地重合 。 当采用重叠的布置方式吋， 显示像素阵列与感光像素可以分别单独地制作， 然后叠加在一起； 当采用交错地布置方式吋， 两种像素阵列可以同吋制作形成
[0039] 显示像素阵列与感光像素的优选布置方式可根据所期望实现的复合功能， 以及 所选择的各种像素的结构和材料类型来确定。 例如， 在感光像素用作感光 （成 像或输入） 功能吋， 显示像素阵列与感光像素可以重叠地布置， 且感光像素位 于显示像素阵列的下方。 又如， 若显示像素阵列选择为 OLED或 AMOLED吋， 显 示像素阵列与感光像素最好各自独立地制作并重叠地布置， 或者感光像素可以 与显示像素阵列的显示控制电路形成于同一半导体基层。 后续将以具体实施例 对几种优选的布置方式进行说明。
[0040] 本发明中的复合显示装置的一种示例性结构可参考图 2， 包括显示像素阵列 Al l ， 感光像素面 A12和周边电路。 所称周边电路包括显示控制电路 A13和感光控制 电路 A14。
[0041] 图 2中， 显示像素阵列 Al l形成为 OLED显示屏 （例如 AMOLED显示屏） 的有机 发光材料层。 显示控制电路 A13采用薄膜驱动电路。 该 OLED显示屏还包括透光 保护层 （阴极） A15。 需要说明的是， OLED显示屏可以是顶部发光， 也可以是 底部发光， 简明起见， 图 2中以顶部发光为例进行绘制， 其中实线箭头表示发光 的方向， 即与外部观看显示面的方向相对的方向。 若采用底部发光的 OLED显示 屏， 则观看方向与本实施例相反， 不再赘述。
[0042] 感光像素面 A12可采用光伏板或具有大尺寸的像素的感光芯片。 感光控制电路 A14可按照功能的需要 （供电， 成像或感光输入等） 进行设计。
[0043] 图 2中， OLED显示屏 （显示像素阵列） 与感光像素面彼此上下重叠地布置。 且 沿外部观看显示面的方向， 感光像素布置于显示像素阵列的下方， 显示像素阵 列至少部分地透光， 使得位于下方的感光像素能够感应到来自外部的光线， 如 图 2中位于上方的虚线箭头所示。 由于感光像素位于显示像素的下方， 本实施例 中， 感光像素感光所覆盖的区域是包含了显示像素发光所覆盖的区域的。
[0044] 需要说明的是， 感光像素面可以是单向感光的， 也可以是双向感光的 （如图 2 中位于下方的虚线箭头所示） 。 在双向感光的情况下， 不论感光像素面布置于 显示像素阵列的上方还是下方， 显示像素阵列最好都具有一定的透光性， 以充 分发挥感光像素的双向感光能力。
[0045] 在其他实施方式中， 沿外部观看显示面的方向， 显示像素阵列也可以布置于感 光像素面的下方， 这种情况下， 感光像素面至少部分地透光。 由于感光像素部 分透明吋会减弱其感光能力， 因此通常而言， 将感光像素设置在显示像素的下 方是更为优选的。
[0046] 本示例中， OLED显示屏可以与感光器件 （包括感光像素面以及感光控制电路
) 分别独立制作， 并在组装吋按照设计重叠在一起， 基于成熟的现有工艺， 这 是一种实现本发明中的复合显示装置的快速而便捷的方法。
[0047] 优选地， 在其他实施方式中， 可以将显示像素阵列的显示控制电路形成于一至 少部分地透光的半导体基层， 而将 （多个） 感光像素也形成于同一半导体基层 。 例如， 显示控制电路可以与感光像素分别形成于该半导体基层的顶面和底面 。 又如， 显示控制电路可以与感光像素至少部分地形成于该半导体基层的同一 面。 以此， 可实现更加集成化的复合显示装置。
[0048]
[0049] 本发明中的感光输入装置为含有光能转换器件的输入装置， 可以是利用感光能 力进行输入的装置， 也可以是触摸板与光电转换器件的叠加。
[0050] 感光输入装置的一种示例性结构可参考图 3， 包括若干个键位 （key
position) B21以及控制和读取电路 (control and readout circuits) B22。
[0051] 每个键位 B21上设置有一透光窗 B211和一光敏器件 B212。
[0052] 透光窗 B211用于外部光线的入射 （如图中虚线箭头所示） ， 其可具有任意的形 状和布置方式。 感光输入装置接受外部光线入射的面即为电子产品的输入面。 不同键位的透光窗可以彼此分隔也可以是一个整体。 例如， 整个输入装置的顶 部可以全部透光， 每个键位所对应的透光区域即可视为该键位的透光窗。 在一 些实施方式中， 透光窗可以是输入装置的面罩 B23上的幵口或通孔。 在另一些实 施方式中， 透光窗也可以是以透明材料制成的窗户， 嵌置在面罩上。 作为一种 优选的实施方式， 透光窗可包括一聚光透镜， 使得入射的外部光线能更好地集 中到光敏器件上。
[0053] 光敏器件 B212设置在透光窗之后的光路上， 其状态与入射的外部光线的光强相 对应。 各种类型的光敏器件均可适用于本发明， 只要其某种可检测的状态能够 根据不同的入射光强产生相应的变化即可。 例如可选择光敏二极管、 光敏电阻 等。 根据光敏器件的不同特性， 其状态变化的方式也可以不同， 例如可以是电 阻值的变化， 也可以是电压值的变化等。 作为一种优选的实施方式， 光敏器件 可采用光伏器件， 例如硅太阳能板或薄膜太阳能电池等， 除了能够提供输入功 育 ， 还能进行光能的转换和利用。
[0054] 控制和读取电路 B22， 用于重置和扫描各个光敏器件， 根据扫描到的各个光敏 器件的状态， 输出表示相应的透光窗被遮挡或不被遮挡的键信号 （key signal) 。 遮挡物 BB可以是例如手指、 输入笔等。
[0055] 由于通过对外部光线的遮挡来改变照射到光敏器件上的光强， 因此装置自身的 光源并不是必要的。 为了能准确识别光敏器件被遮挡的状态， 控制和读取电路 在扫描键位之前需要先重置光敏器件， 以消除已经积累的光照的影响。 所称重 置指将光敏器件恢复到未经光线照射的状态， 可采用例如清零或复位的方式。 对于不同的光敏器件， 清零或复位的具体方法可能各有不同， 例如， 通常可通 过在信号的读取端施加一个零电压或反向电压来实现。 具体的清零或复位方式 ， 可根据所使用的光敏器件自身的特性来确定。
[0056] 控制和读取电路的扫描方式可参照现有的键盘或触摸屏等的扫描方式， 本发明 对此不予限定。 例如， 可采用周期性扫描的方式， 也可采用触发式扫描的方式 ； 每次扫描吋， 可按照预定的吋间间隔逐个扫描每一键位， 也可同吋扫描全部 键位。
[0057] 控制和读取电路所采用的用于判断键位状态的逻辑可根据实际应用的情况来设 计。 例如， 可设置一参数阈值， 当光敏器件的某个随光强变化的参数 （例如光 敏电阻的电阻值、 光敏二极管的电压值等） 小于 （或大于） 所设置的阈值吋， 即认为该键位被遮挡， 从而产生一次输入。 又如， 可设置一变化幅度的阈值， 当光敏器件的被测参数的变化幅度大于所设置的阈值吋， 即认为该键位被遮挡 ， 从而产生一次输入。 作为判断依据的变化幅度可以是变化的绝对值 （例如相 对于上一次扫描获得的参数值的差值） ， 也可以是变化的比例 （例如相对于未 受遮挡情况下的参数值变化的比例， 其中未受遮挡情况下的参数值可持续更新 ) 。 在某些应用情况下， 后者是优选的， 以便于在外界光强发生变化吋仍能准 确判断键位被遮挡的状态。 此外， 还可进一步采用这样的判断逻辑， 即仅在键 位状态由无遮挡变化为遮挡吋视为一次输入， 而在键位状态保持为遮挡吋， 或 者由遮挡变化为无遮挡吋则不视为输入。 这样， 长吋间的遮挡某一键位仅产生 一次输入， 需要将遮挡物移幵后再行遮挡才会产生第二次输入。
[0058] 控制和读取电路所采用的输出键信号的方式可根据实际应用的需要来设计。 例 如， 可仅输出判断为透光窗被遮挡或不被遮挡的键位的键值 （key value) ， 也可 采用位图 （bitmap) 的形式输出表示全部键位的状态的信号。 需要说明的是， 每 个键位代表的是一个物理键， 与传统键盘类似， 一个物理键也可以是多个虚拟 键的复合键， 可通过预先设置的输入规则 （例如多个键的组合） 来进行区分， 不再赘述。
[0059] 通过设计感光输入装置的键位大小、 排布方式以及整体结构， 可以实现各种不 同的输入功能。 在一种实施方式中， 将键位设计为普通键盘的按键大小， 按照 设定的规则进行排布， 即可使得感光输入装置形成为键盘。 为便于标识， 可在 不干扰透光窗的位置印刷或粘贴与键位对应的字母或符号等。 在另一实施方式 中， 可设计尺寸为毫米级或者更小的键位， 多个键位排布为密集的二维阵列， 顶部形成为平坦的整体， 使得感光输入装置形成为滑动输入板。 当然， 不同的 键位布置方式也可集合在一个输入装置中， 例如， 形成为带有滑动输入板的键
[0060] 由于无需被按下， 本发明中的感光输入装置的全部键位可形成为一个整体， 例 如图 3所示， 顶部可采用一体成型的多孔板， 在透光窗处镂空或以透明元件封闭 ， 底部可采用整体的印刷线路板 （PCB) 或柔性线路板 （FPC) 等， 从而将光敏 器件以及控制和读取电路集成在一起。 这种结构能够很容易地具有超薄且防水 、 防尘的优越特性。 在其他实施方式中， 键位也可以彼此分离， 从而具有更类 似于现有键盘的观感， 相应地， 承载光敏器件的线路板也可分割为多块。
[0061] 作为一种优选的实施方式， 还可将感光输入装置与现有压力输入装置相结合。
即， 在至少一个键位上设置压敏器件， 这种情况下， 控制和读取电路还用于输 出表示相应的压敏器件被触发的键信号。 所采用的压敏器件可以是弹性按键机 构 (Elastic switch mechanism) 、 触摸屏 (touch screen) 等。 例如， 可以在传统 键盘的键帽上设置透明窗并在键帽内设置光敏器件， 此吋， 一个键位即可提供" 被遮挡 "以及 "被遮挡且被按下"两种输入状态， 使得键位的表达能力倍增。 又如 ， 可以在传统的触摸屏 （透光） 下方设置感光输入装置， 例如前述的滑动输入 板， 当手指仅遮光吋由光敏器件响应， 当手指触摸屏幕吋则由触摸屏响应， 从 而在一个键位产生两种不同的输入。 这种组合式的输入结构由于具有更丰富的 输入表达能力， 可以一键双用， 因此能够在空间有限的情况下， 通过键位的重 复利用， 增大单个物理键位的尺寸， 既使得使用更加方便， 也提高了输入的效 率。
[0062]
[0063] 感光输入装置的另一种示例性结构可参考图 4， 包括触摸板 C21和基板 C24。
[0064] 触摸板 C21是透明的， 用于响应于用户的触摸操作产生输入信号。 触摸板所在 的面即为电子产品的输入面。
[0065] 基板 C24， 位于触摸板的下方， 在图 4中以虚线表示。 基板形成为光电转换器件 ， 能够将照射到自身表面的光能转换为电能。 由于输入装置通常具有较大的表 面积， 因此充当光能转换器的基板有能力提供足够的电能。 基板所产生的电能 可用于为电子产品自身供电， 或者也可用于为外部设备 （例如手机） 供电。
[0066] 触摸板 C21可包括至少一个按键区域 C211， 用户在每个按键区域中的触摸操作 所产生的输入信号为与该按键区域对应的按键信号。 用于表示出按键区域的图 案 CC可设置在触摸板或者基板的表面。 例如以印刷、 蚀刻或投影等方式显现在 触摸板的上表面或下表面或基板靠近触摸板的表面。 图案 CC既可以包括表示按 键区域的边框， 也可以包括表示输入信号的字符或符号等， 以便于用户使用。
[0067]
[0068] 依据本发明的电子产品还可以额外附加其他外部设备 （例如扬声器和麦克风） 或者与其他外部设备集成为一体， 因此可根据实际应用需要为电子产品配置各 种附加功能模块， 例如， 可包括选自如下模块中的一种或多种：
[0069] 电源供应模块： 用于为其他用电模块供电； 可以是储能式的电源模块， 例如可 充电或不可充电的电池、 超级电容、 固体平板电容、 聚合物平板电容等； 也可 以是用于外接供电电路的电源转换器； 还可以是光电转换器件， 其既可以是显 示装置或输入装置中的光电转换器件， 也可以是额外配置的光电转换器件， 例 如可设置在显示装置或输入装置的背面， 使得电子产品在各种翻转角度下均可 自行充电；
[0070] 通信模块： 用于与其他电子产品进行通信， 传输键信号等； 可以是有线或无线 通信模块， 例如红外通信模块、 公用无线电频段通信模块、 蓝牙模块、 WiFi模 块、 WiMax模块、 2G/3G/4G/5G通信模块等； 值得一提的是， 用于远距离无线通 信的通信模块， 例如 3G/4G等， 在类似于电脑键盘这样的应用中可能没有必要， 但对于手持式收银终端、 移动式客户服务平台的终端等远程分布式设备， 是优 选采用的；
[0071] 附加输入模块： 用于通过其他方式采集输入信息的模块； 例如用于输入指纹或 掌纹的影像采集模块， 用于输入声音信号的语音识别模块， 用于输入控制信号 的专用按键 （可以是压力按键也可以是感光式按键） 等； 这些模块的输入信息 可以与感光输入装置的输入信息交替或配合使用；
[0072] 振动能量转换器： 用于将电子产品的动能转换为电能， 这样即便电子产品被放 在包里或口袋里， 无法通过光能充电， 也能通过用户的移动为产品充电；
[0073] 摄像头： 可设置在显示面或输入面所在的表面上， 可以有一个或多个；
[0074] 存储模块： 可包括闪存 （SD) 卡、 微型闪存 （Micro
SD) 卡、 硬盘、 磁内存 （MRAM) 等模块；
[0075] 接口模块： 用于连接各种外部设备， 可包括串联接口、 并联接口、 USB接口、 存储卡 （例如 SD卡、 TFT卡） 接口， 外部扬声器和麦克风接口、 网线接口等。 [0076] 以下对依据本发明的电子产品的具体应用形式进行举例说明。 以上各种说明和 解释， 如无冲突， 均适用于依据本发明的各种实施方式。
[0077] 实施例 1
[0078] 依据本发明的电子产品的一种实施方式可参考图 5， 包括复合显示装置 110和感 光输入装置 120， 两个装置在其边缘处通过机械转轴 130可转动地连接。 本实施 例中， 转轴的转动角度范围为 0-130度， 该电子产品适用于作为移动电脑使用。
[0079] 复合显示装置 110的显示面与感光输入装置 120的输入面彼此相对， 显示面与输 入面被称为各自所在装置的 "正面"， 装置的另一面则被称为"背面"， 以下均沿用 这些概念， 不再赘述。
[0080] 本实施例中， 感光输入装置 120采用类似于图 4的结构， 包括透明的触摸板 121 和位于其下方的由光伏薄膜形成的基板 124。 这种结构不仅有助于降低移动电脑 的厚度， 还能够延长其续航吋间。 复合显示装置的背面还可设置额外的光伏器 件， 尤其是能够吸收室内光线的光伏器件， 能够进一步提高移动电脑的续航吋 间。
[0081] 此外， 若本实施例电子产品采用无线通信及无线充电方式， 则电子产品的整个 外表面可形成为封闭的整体， 以达到防水防尘的效果。
[0082] 实施例 2
[0083] 依据本发明的电子产品的另一种实施方式可参考图 6， 包括复合显示装置 210和 感光输入装置 220， 两个装置在其边缘处通过两个机械转轴 230可转动地连接。 本实施例中， 转轴的转动角度范围为 0-360度， 该电子产品可主要作为手机使用 ， 也可根据需要切换于不同的使用模式。
[0084] 当复合显示装置 210和感光输入装置 220背面相对折叠在一起吋 （旋转角度为 36 0度） ， 该电子产品可以象普通的手机一样使用， 复合显示装置既用于显示又用 于输入， 而位于背面的感光输入装置则用于充电。 当两个装置的旋转角度为 90-1 20度吋， 该电子产品的使用方式与移动电脑类似。 当两个装置的旋转角度为 180 度吋， 该电子产品则可作为平板电脑使用。
[0085] 感光输入装置 220可采用图 3或图 4的结构。 为增加续航吋间， 复合显示装置 210 的背面还设置有光伏器件， 这样， 无论如何折叠， 该手机都至少有一个面能够 接受外部的光能。
