以下, 将详细描述本公开的实施例, 其示例在附图中示出。 应当理解, 这些描述 只是示例性的, 而并非要限制本公开的范围。
根据本公开的一些实施例, 可以在显示模组中集成反射型屏幕及触摸技术, 开发 新型触摸型显示器的结构。
根据一实施例, 显示模组例如可以包括:
满足第一透光率的覆盖单元, 包括一触摸区域;
满足第二透光率的感应单元, 包括一感应层, 其中覆盖单元设置于感应层的第一 侧,感应层被配置为当一操作体触摸触摸区域时,感应操作体在触摸区域的触摸位置; 反射型显示单元, 包括显示层和反射表面, 显示单元设置于感应层的第二侧, 且 显示层和反射表面分别与感应层相对, 显示单元被配置为通过显示层显示图像, 其中 当一入射光照射到反射表面后形成一能透过感应单元和覆盖单元的反射光。
图 1为根据本公开第一实施例的显示模组的结构示意图。 参阅图 1, 根据该实施例 的显示模组 100包括覆盖单元 110、 感应单元 120和反射型显示单元 130。
覆盖单元 110可以满足第一透光率,且包括相对的第一表面 111和第二表面 112。在 本公开中, 所谓某部件 "满足透光率", 是指光线通过该部件的通过率达到一定要求, 从而该部件呈基本上完全透明或满足可视需求的半透明状, 且制作材料不限定颜色和 材质。 具体地, 满足第一透光率的覆盖单元 110的光线通过率至少达到第一透光率要 求。 以下所述的第二透光率、 第三透光率和第四透光率同样如此。
感应单元 120可以满足第二透光率, 且包括相对的第一感应面 121和第二感应面 122。在图 1所示的示例中,感应单元 120设置于覆盖单元 110的一侧(图中所示的下侧), 且第一感应面 121与第二表面 112相对。 在这种情况下, 第一感应面 121与第一表面 111 之间的第一距离大于第一感应面 121与第二表面 112之间的第二距离。 感应单元 120被 配置为当一操作体 (例如, 手指或触摸笔) 触摸覆盖单元 110的第一表面 111的一触摸 区域时, 感应该操作体在触摸区域的触摸位置。 本领域技术人员可以理解, 感应单元 中的感应面也可以称之为感应层, 这两者在本公开中可互换使用。 例如, 该示例中感 应单元 120的第一感应面 121和第二感应面 122也可以分别称为第一感应层 121和第二 感应层 122。
反射型显示单元 130设置于感应单元 120的一侧 (图中所示的下侧), 且可以包括 显示层 131和反射表面 132, 显示层 131和反射表面 132分别与第二感应面 122相对。 在 图 1所示的示例中, 反射表面 132与第二感应面 122之间的距离小于反射表面 132与第一 感应面 121之间的距离, 反射表面 132与第二感应面 122之间的距离大于或等于显示层 131与第二感应面 122之间的距离。 显示单元 130可以通过显示层 131显示图像。 当一入 射光照射到反射表面 132后能形成一透过感应单元 120和覆盖单元 110的反射光。
在图 1所示的示例中, 覆盖单元 110、 感应单元 120和显示单元 130由上至下依次排 列。 本领域技术人员可以理解, 除上述结构形式之外, 覆盖单元 110、 感应单元 120和 显示单元 130也可以形成为由下至上、 由左至右或者由右至左等其他排列结构。
在根据第一实施例的显示模组 100中, 当环境光达到足够亮度时, 能够穿透覆盖 单元 110、 感应单元 120到达反射表面 132, 形成为入射光。 该入射光经过反射表面 132 反射后, 又依次穿透感应单元 120和覆盖单元 110, 反射出来, 传输至位于覆盖单元 110 上方用户的眼睛里, 使用户可以看到显示层 131所显示图像。 也即, 根据第一实施例 的显示模组 100是反射型显示结构。
根据一示例, 显示单元 130例如可以包括反射型液晶显示屏, 其中反射表面 132设 置于显示层 131的一侧 (图中所示的下侧)。 在这种情况下, 反射表面 132与第二感应 面 122之间的距离大于显示层 131与第二感应面 122之间的距离。 如图 1所示, 当显示单 元 130位于感应单元 120下方时,反射表面 132位于显示层 131的下方,使经反射表面 132 反射的光能够透过显示层 131, 用户能够看到显示层 131显示的图像。 本领域技术人员 应该可以理解反射型液晶显示屏的结构, 在此不具体详细描述。
根据另一示例, 显示单元也可以包括电子纸 E-ink显示屏。 在该类型显示单元中, 反射表面可以形成在显示层面对感应单元一侧的表面上, 即反射表面与第二感应面之 间的距离可以等于显示层与第二感应面之间的距离。 入射光到达反射表面后直接向上 反射, 使用户看到显示层所显示图像。 包括该种类型显示单元的显示模组结构与第一 实施例相同, 在此不再详述。
根据其他示例, 反射型显示单元还可以包括其他反射原理的显示单元 (比如 electrowetting显示屏)。 本公开不限于显示单元的具体类型。
此外, 根据一些实施例, 显示单元可以包括由像素阵列构成的整个显示屏幕, 或 者可以包括一个或多个像素点。
在本公开的第一实施例中, 覆盖单元 110、 感应单元 120应该满足入射光和反射光 双方向透光要求。
根据一示例, 感应单元 120可以形成为一电阻感应式结构。 例如, 感应单元可以 包括多层复合薄膜配置。 具体地, 可以提供一层玻璃或有机玻璃作为基层, 该基层上 表面涂有一层透明的第一导电层 (例如, ITO膜),基层的上方再设置一层外表面经过硬 化处理、 光滑防刮的塑料层, 该塑料层的内表面形成有第二导电层。 在第一导电层和 第二导电层之间可以设置许多细小 (例如, 小于千分之一英寸)的透明隔离点。 当手指 接触覆盖单元 110时, 第一导电层和第二导电层发生接触, 电阻发生变化。 可以根据 这种电阻变化来计算接触点的坐标, 再依照这个坐标来进行相应的操作, 获得触摸操 作效果。
根据另一示例, 感应单元 120可以形成为一电容感应式结构。 例如, 感应单元 120 可以包括四层复合玻璃屏。 当手指在覆盖单元 110上接触时, 在人体和覆盖单元 110之 间可以形成耦合电容。 对于高频电流来说, 电容是直接导体, 于是手指可以从接触点 带走一个很小的电流。 该电流分别从覆盖单元 110触摸区域四角上的电极中流出, 并 且流经该四个电极的电流与手指到四角的距离成正比。 可以通过对这四个电流比例的 计算, 得出触摸点的位置信息, 从而进行与该触摸位置相关的操作, 获得触摸操作的 效果。
在根据上述实施例的显示模组中, 采用了诸如电阻感应式或电容感应式结构的感 应单元和反射型显示单元, 使反射式显示屏幕和单点触摸技术相结合, 形成为一种新 型结构的触摸显示模组。
本领域技术人员应该能够理解感应单元 120分别形成为电阻感应式结构和电容感 应式结构时的具体结构, 在此不再分别详细描述。
另一方面, 感应单元 120也可以为一多点触摸式结构, 从而可以允许用户在显示 屏幕的多个位置同时输入, 并可以识别用户操作手指的姿态。
图 2中示出了根据一实施例感应单元 120形成为多点触摸式结构时的结构示意图。 如图 2所示, 第一感应面 121上设置有多条不相交的第一感应线 1211, 第二感应面 122 上设置有多条不相交的第二感应线 1221。 第一感应线 1211投影至第二感应面 121的投 影线与第二感应线 1221相交, 或者第二感应线 1221投影至第一感应面 121的投影线与 第一感应线 1211相交, 从而第一感应线 1211和第二感应线 1221形成为行列相交叉的互 电容, 即耦合电容。
利用上述结构, 当操作者触摸覆盖单元 110第一表面 111的触摸区域时, 感应单元 120的第一感应面 121和第二感应面 122上相对应位置的互电容发生变化。 根据这种变 化, 可以判断触摸存在, 并可以判断每一触摸点位置。
此外, 第一感应线 1211和第二感应线 1221不限于分别包括相互平行的感应线, 而 是可以形成为其他配置。 图 3中示出了一种示例配置, 其中第一感应线 1211和第二感 应线 1221弯折, 只要能够保证每一第一感应线 1211在第二感应面 122上的投影线分别 与第二感应线 1221交叉, 或者每一第二感应线 1221在第一感应面 121上的投影线分别 与第一感应线 1211交叉即可。
因此,在根据以上实施例的显示模组中,结合了反射式显示屏幕和多点触摸技术, 形成为一种新型结构的触摸显示模组。
根据本公开的另一实施例, 显示模组还可以包括一发光单元, 用于为反射型显示 单元提供入射光。
图 4示出了根据本公开第二实施例的显示模组的结构示意图。 参阅图 4, 根据第二 实施例的显示模组 200包括具有第一透光率的覆盖单元 210、 具有第二透光率的感应单 元 220、 反射型显示单元 230和发光单元 240。
在此, 覆盖单元 210、 感应单元 220和反射型显示单元 230的配置可以与第一实施 例中显示模组 100的覆盖单元 110、 感应单元 120、 反射型显示单元 130的配置相同。
发光单元 240可以设置于感应单元 220和反射型显示单元 230之间, 发光单元 240的 发光面与显示单元 230的显示层 231相对设置。 发光单元 240具有能够沿反射光的方向 透光的第三透光率, 而感应单元 220则至少能够沿反射光方向透光, 以使得反射光经 反射表面 232反射后, 能够透过发光单元 240、 感应单元 220和覆盖单元 210, 传输至位 于覆盖单元 210上方用户的眼睛里, 使用户可以看到显示层 231所显示图像。
类似地, 发光单元 240也可以设置于覆盖单元 210和感应单元 220之间。
图 5示出了根据本公开第三实施例的显示模组 300的结构示意图。
与第一实施例和第二实施例类似, 根据该实施例的显示模组 300包括覆盖单元 310、 感应单元 320和反射型显示单元 330。 这三个单元的配置可以分别与第一实施例 和第二实施例中的覆盖单元、 感应单元和显示单元的配置相同, 在此不再具体描述。
如图 5, 显示模组 300还可以包括发光单元 340和匀光单元 350。 发光单元 340发射 光以用作显示单元 330的入射光。 匀光单元 350设置于显示单元 330和感应单元 320之 间, 且具有能够沿反射光方向透光的第四透光率。 发光单元 340设置于匀光单元 350的 任一侧或两侧, 匀光单元 350用于均匀传导发光单元 340发出的光, 使发光单元 340所 发出的光均匀照射至反射表面 332, 形成入射光。
经反射表面 332反射的反射光透过匀光单元 350、 感应单元 320和覆盖单元 310传输 至外面, 使用户可以看到显示层 331所显示图像。
发光单元 340可以集成于显示模组 300上, 也可以与显示模组 300相互独立设置。 图 6示出了根据本公开第四实施例的显示模组 400的结构示意图。
如图 6所示, 根据该实施例的显示模组 400包括依次设置的覆盖单元 410、 感应单 元 420和反射型显示单元 430。
覆盖单元 410可以满足第一透光率, 且包括相对的第一表面 411和第二表面 412。 感应单元 420可以满足第二透光率, 且包括相对的第一感应面 421和第二感应面 422。在图 4所示的示例中,感应单元 420设置于覆盖单元 410的一侧(图中所示的下侧), 且第一感应面 421与第二表面 412相对。 在这种情况下, 第一感应面 421与第一表面 411 之间的第一距离大于第一感应面 421与第二表面 412之间的第二距离。 感应单元 420被 配置为当一操作体 (例如, 手指或触摸笔) 触摸覆盖单元 410的第一表面 411的一触摸 区域时, 感应该操作体在触摸区域的触摸位置。
反射型显示单元 430设置于感应单元 420的一侧 (图中所示的下侧), 且可以包括 显示层 431和反射表面 432, 显示层 431和反射表面 432分别与第二感应面 422相对。 在 图 4所示的示例中, 显示层 431与第二感应面 422之间的距离小于显示层 431与第一感应 面 421之间的距离。 显示单元 430可以通过显示层 431显示图像。 当一入射光照射到反 射表面 432后能形成一透过感应单元 420和覆盖单元 410的反射光。
因此, 与第一至第三实施例相同, 第四实施例中的覆盖单元 410、 感应单元 420和 显示单元 430形成为由上至下依次设置的结构。
此外, 在第四实施例中, 如图 6所示, 感应单元 420可以包括一发光层 423, 设置 于第一感应面 421和第二感应面 422之间。发光层 423朝向显示层 431,用于提供入射光。
例如, 发光层 423可以包括一满足第二透光率 (也即呈基本上透明或达到一定透光 要求呈半透明)的有机发光二极管 (OLED)。一方面, OLED发出的光具有良好的单向性, 从而可有效地朝向反射表面 432发光; 另一方面, OLED在出光反方向可以具有高透光 率特性, 使经反射表面 432反射的反射光透过 OLED也即发光层向上传输至覆盖单元 410。
根据一示例,可以在发光层 423如 OLED发光层的基本玻璃的第一表面上覆盖电容 介质, 形成为第一感应面 421 ; 可以在发光层 423如 OLED发光层的基本玻璃上与第一 表面相对的第二表面上覆盖电容介质, 形成为第二感应面 422。 感应单元 420可以利用 第一感应面 421和第二感应面 422而构成多点触摸感应结构。
本领域技术人员应该能够了解透明 OLED的结构,并应该能够了解在 OLED的上下 表面集成多点触摸感应结构的具体实施工艺和实现方式, 在此不详细描述。 因此,在根据第四实施例的显示模组 400中,例如利用透明 OLED作为显示单元 430 的前照光, 并与多点触摸感应结构集成为一体, 形成为新型触摸显示器的结构, 且可 以达到减少整个模组厚度又节省相应制作工艺和成本的目的。
形成为多点触摸感应结构的第一感应面 421和第二感应面 422的具体结构例如可 以参阅以上结合图 2和 3关于多点触摸感应的描述, 在此不再赘述。
如上所述, 在根据本公开实施例的显示模组中, 可以集成反射型显示面板及触摸 技术, 另外还可以相对于反射型显示面板设置前照光源, 构成为一种新型反射式触摸 显示器结构。
图 7为根据本公开一实施例的电子设备 1000的相关部分的结构示意图。 如图 7所 示, 根据该实施例的电子设备 1000可以包括覆盖单元 110、 感应单元 120、 反射型显示 单元 130和处理单元 140。
覆盖单元 110可以满足第一透光率, 且包括相对的第一表面 111和第二表面 112。 感应单元 120可以满足第二透光率, 且包括相对的第一感应面 121和第二感应面 122。在图 7所示的示例中,感应单元 120设置于覆盖单元 110的一侧(图中所示的下侧), 且第一感应面 121与第二表面 112相对。 在这种情况下, 第一感应面 121与第一表面 111 之间的第一距离大于第一感应面 121与第二表面 112之间的第二距离。 感应单元 120被 配置为当一操作体触摸覆盖单元 110的第一表面 111的一触摸区域时, 感应该操作体在 触摸区域的触摸位置。
反射型显示单元 130设置于感应单元 120的一侧 (图中所示的下侧), 且可以包括 显示层 131和反射表面 132, 显示层 131和反射表面 132分别与第二感应面 122相对。 在 图 7所示的示例中, 反射表面 132与第二感应面 122之间的距离小于反射表面 132与第一 感应面 121之间的距离。 显示单元 130可以在显示层 131显示图像。 当一入射光照射到 反射表面 132后能形成一透过感应单元 120和覆盖单元 110的反射光。
处理单元 140可以被配置为根据感应单元 120感应到的触摸位置, 生成与该触摸位 置对应的操作指令。
在该实施例中, 覆盖单元 110、 感应单元 120和显示单元 130可以形成为以上结合 图 1所述的的显示模组 100。 具体地, 例如该显示模组中的显示单元 130可以包括液晶 显示屏。
根据另一实施例,显示单元也可以包括电子纸 E-ink显示屏。在该类型显示单元中, 反射表面可以形成在显示层面对感应单元一侧的表面上。 在采用该种类型显示单元的 情况下, 显示单元相对于覆盖单元和感应单元的配置可以如图 7所示的情况, 在此不 再详述。
根据本公开的实施例, 感应单元 120可以形成为电阻感应式、 电容感应式或多点 触摸感应式, 例如可以参见以上结合第一实施例的描述, 在此不再赘述。
根据其他实施例, 电子设备中的显示模组也可以包括根据本公开其他实施例的显 示模组, 例如图 4至图 6中所示的任何一个显示模组。
当显示模组实现为如图 4或图 5所示的形式时, 显示模组还可以包括发光单元, 用 于为显示单元提供入射光。 在这种情况下, 电子设备还可以包括一检测单元, 用于检 测环境光亮度值, 并判断环境光亮度值是否大于或等于一预设亮度值。 处理单元 140 还可以被配置为当环境光亮度值大于或等于预设亮度值时, 关闭发光单元; 而当环境 光亮度值小于预设亮度值时, 打开发光单元。
图 8为根据本公开另一实施例的电子设备的结构示意图。 根据该实施例的电子设 备 2000包括以上结合第二实施例所述的显示模组 200、 处理单元 250和检测单元 260。
如上所述, 显示模组 200可以包括覆盖单元 210、 感应单元 220、 反射型显示单元 230和发光单元 240。 对于该显示模组 200的配置, 可以参见以上结合第二实施例的描 述, 在此不再赘述。
处理单元 250可以被配置为根据感应单元 220感应到的触摸位置, 生成与该触摸位 置对应的操作指令。
检测单元 260可以被配置为检测环境光亮度值, 并可以判断环境光亮度值是否大 于或等于一预设亮度值。 根据一示例, 该预设亮度值被设置为使用户清楚看到显示单 元 230所显示图像需要的最小亮度值。
当检测单元 260判断环境光亮度值小于该预设亮度值, 也即环境光不能为显示单 元 230提供足够亮度光线使用户看清楚显示层 231所显示图像时, 处理单元 250可以根 据检测单元 260的判断结果, 打开发光单元 240, 由发光单元 240照射反射表面 232, 提 供单元单元 230的入射光。 此时, 发光单元 240具有能够沿反射光的方向透光的第三透 光率, 而感应单元 220则也能够沿反射光方向透光, 以使得反射光能够透过发光单元 240、 感应单元 220和覆盖单元 210, 传输至位于覆盖单元 210上方用户的眼睛里。
当检测单元 260判断环境光亮度值大于或等于该预设亮度值, 也即环境光能够为 显示单元 230提供足够亮度光线使用户看清楚显示层 231所显示图像时, 处理单元 250 可以根据检测单元 260的判断结果, 关闭发光单元 240, 由环境光提供显示单元 230的 入射光。 此时, 发光单元 240和感应单元 220不但应该能够在反射光方向透光, 而且还 应该能够在入射光方向透光, 以使得环境光能够穿透覆盖单元 210、 感应单元 220到达 反射表面 232, 形成为入射光, 该入射光经过显示层 231反射后, 又依次穿透感应单元 220和覆盖单元 210, 反射出来, 传输至位于覆盖单元 210上方用户的眼睛里。
这里需要指出的是, 在上述实施例中, 由检测单元 260来判断环境光亮度值是否 大于或等于预设亮度值。 但是, 本公开不限于此。 例如, 该判断操作可以由处理单元 250来进行, 而检测单元 260被配置为检测环境光亮度并将检测到的环境光亮度输入到 处理单元 250中。
类似地, 电子设备也可以采用结合图 5所述的第三实施例的显示模组。 在这种情 况下, 也可以设置用于检测环境光亮度值的检测单元, 从而处理单元可以根据检测单 元的检测结果, 控制发光单元的亮、 灭。
根据上述实施例, 通过设置检测单元, 检测环境光亮度值, 以控制发光单元的打 开或关闭, 能够达到节省电子设备耗电量的目的。
类似地, 电子设备也可以采用结合图 6所述的第四实施例的显示模组, 在该显示 模组中, 在感应单元的第一感应面和第二感应面之间设置发光层如 OLED发光层。
根据该实施例, 可以在发光层如 OLED发光层的基本玻璃的第一表面上覆盖电容 介质, 形成为第一感应面; 可以在发光层如 OLED发光层的基本玻璃上与第一表面相 对的第二表面上覆盖电容介质, 形成为第二感应面。 感应单元可以利用第一感应面和 第二感应面构成为显示模组的多点触摸感应结构。
对于该显示模组的具体配置, 例如可以参见以上结合第四实施例的描述, 在此不 再赘述。
根据本公开的一个实施例, 还提供了一种电子设备的控制方法。 电子设备可以包 括反射型显示单元和发光单元, 其中发光单元被配置为向显示单元的显示层发光。 显 示单元可以包括一显示层, 用于显示图像。 显示单元的显示层接收发光单元所发射的 入射光, 将入射光反射至位于显示层上方用户的眼睛里, 使用户能够看到显示层所显 示图像。
具体地, 该控制方法可以包括: 检测环境光亮度值; 判断环境光亮度值是否大于 或等于一预设亮度值; 当环境光亮度值大于或等于预设亮度值时, 关闭发光单元; 当 环境光亮度值小于预设亮度值时, 打开发光单元。
根据本公开的另一实施例, 还提供了一种电子设备的控制方法, 电子设备可以包 括满足第一透光率的覆盖单元、 满足第二透光率的感应单元、 反射型显示单元和发光 单元。 覆盖单元可以包括一触摸区域。 感应单元可以包括一感应层, 覆盖单元可以设 置于感应层的第一侧。 感应层可以被配置为当一操作体触摸触摸区域时, 感应操作体 在触摸区域的触摸位置。 反射型显示单元可以包括显示层和反射表面。 显示单元可以 设置于感应层的第二侧, 显示层和反射表面分别与感应层相对。 显示单元可以通过显 示层显示图像。 当一入射光照射到反射表面后形成一能透过感应单元和覆盖单元的反 射光。 发光单元可以被配置为提供入射光。
电子设备中的显示模组例如是以上结合图 1、 图 4至图 6描述的显示模组。 对于这 些显示模组的具体配置, 参见以上描述, 在此不再赘述。
具体地, 该控制方法可以包括: 检测环境光亮度值; 判断环境光亮度值是否大于 或等于一预设亮度值; 当环境光亮度值大于或等于预设亮度值时, 关闭发光单元; 当 环境光亮度值小于预设亮度值时, 打开发光单元。
根据上述方法, 通过检测环境光亮度值, 以控制发光单元的打开或关闭, 能够达 到节省电子设备耗电量的目的。
根据本公开的一些实施例, 可以在显示模组中集成反射型显示单元及触摸感应技 术, 此外还可以在显示单元上方额外设置前照发光光源, 为显示单元提供照射光。 从 而可以提供一种新型触摸显示器。
根据本公开的一些实施例, 感应单元与发光层可以相组合设置, 能够达到减少整 个模组厚度又节省相应制作工艺和成本的效果。
根据本公开的一些实施例, 可以设置检测单元, 检测环境光亮度值, 以控制发光 单元的打开或关闭, 能够达到节省电子设备耗电量的目的。
