本发明实施方式提供一种显示方法、 显示装置和显示屏。 以下参考附图 对本发明进行详细说明。
实施方式一
本发明提供一种显示方法, 该方法包括: 提供白色反光板, 该白色反光 板自身反光以产生白色光; 在该白色反光板之上或外侧设置彩色透光板, 使 得该白色光透过彩色透光板反射出来时显示相应的色彩。
由上述可知, 通过白色反光板产生的白色光透过彩色透光板反射出来而 显示色彩, 与液晶显示装置或 LED显示屏相比, 不需要发光, 因此不消耗电 能, 既节能又环保。
上述彩色透光板可为一个或多个, 数量不限, 可根据实际需要显示的色 彩来确定。
如图 3A所示,在白色反光板 301之上设置彩色透光板 302。如图 3B所示, 在白色反光板 301之上设置彩色透光板 302和彩色透光板 303。如图 3C所示, 在白色反光板 301之上设置彩色透光板 302、 彩色透光板 303和彩色透光板 304。
当彩色透光板为多个时, 设置该彩色透光板的顺序不受限制, 可任意排 列。 上述白色反光板和彩色透光板之间、 或彩色透光板之间可间隔一定的距 离, 也可贴合在一起。
上述彩色透光板与白色反光板之间、 或彩色透光板之间可互相完全重叠、 或部分重叠, 当彩色透光板为多个时, 多个彩色透光板之间也可以完全重叠, 也可以部分重叠, 以产生所需要的色彩, 如图 3D所示。
在完全重叠的情况下:
如图 3A所示, 当彩色透光板为 1个时, 所显示的色彩为该彩色透光板的 颜色; 如图 3B所示, 当彩色透光板为 2个时, 所显示的色彩为 2个彩色透光 板叠加产生的颜色; 如图 3C所示, 彩色透光板为 3个时, 所显示的色彩为 3 个该彩色透光板叠加产生的颜色。
在部分重叠的情况下, 如图 3D所示, 所显示的色彩为上述一个彩色透光 板、 两个或三个彩色透光板完全叠加所能产生的几种色彩之外的由这几种色 彩所组成的混合色彩。 比如, 当一个彩色透光板只有百分之五十的部分参加 与白色反光片或其他彩色透光板的叠加时, 则这个色彩只有百分之五十被显 示出来, 整体显示出来的色彩也就不同于百分之百的部分参加组合叠加时的 色彩。 因此, 当任何一个彩色透光板参与组合叠加的部分的百分比变化时, 将相应地产生一组不同色彩, 相当于色彩的灰度变化, 也就使得本发明所发 明的显示方法在色彩的表现上丰富多样。
上述彩色透光板 302、 303、 304可采用任何材料的彩色透光板。
在本实施方式中, 上述彩色透光板 302、 303、 304采用彩色透光玻璃或 彩色透光塑料; 或者彩色透光板采用透明玻璃或透明塑料, 该透明玻璃或透 明塑料的表面贴覆有彩色透光膜。
在本实施方式中, 彩色透光板 302、 303、 304采用为利用胆固醇原理或 液晶原理控制透光度的彩色透光片或透光膜。
上述白色反光板 301可采用任何材料的白色板。
在本实施方式中, 白色反光板 301 采用白色的塑料板、 或白色纸板、 或 白色铝片、 或白色铝合金片; 或者白色反光板 301采用塑料板、 或纸板、 或 铝片、 或铝合金片, 该塑料板、 纸板、 铝片、 铝合金片的表面贴覆有白色反 光膜。
在本实施方式中, 白色反光板 301 采用利用胆固醇原理或液晶原理控制 反光度的白色反光膜。
上述白色反光板和彩色透光板的几何尺寸和形状任意, 不受限制。
本实施方式中可为平面板形, 如图 3A至 3D所示。
上述白色反光板和彩色透光板还可为半柱形、 柱形, 或者白色反光板为 柱形, 彩色透光板为半柱形, 如图 4A至 4D所示。
如图 4A、 4B所示, 为本实施方式中采用半圆柱形的剖面示意图; 如图 4C 和 4D所示, 为本实施方式中采用圆柱形的剖面示意图和侧视图。 如图 4D所 示, 当彩色透光板的形状为圆柱形时, 该圆柱形的一部分为透明体, 另一部 分为彩色透光体。
如图 4A至 4D所示, 该方法还包括: 设置旋转轴 405和支撑该旋转轴 405 的支架 406, 其中, 旋转轴 405支撑白色反光板和彩色透光板, 这样, 可在 手或者外部电机控制下驱动彩色透光板、 或者驱动彩色透光板和白色反光板 围绕旋转轴 405旋转, 若白色反光板 401与彩色透光板贴合在一起时, 白色 反光板 401 也随彩色透光板一起旋转; 然后, 根据该彩色透光板和白色反光 板的重叠方式来显示相应的色彩。 其中, 在彩色透光板为半柱形的情况下, 如图 4A所示, 半柱形彩色透光板的底部采用园盘与旋转轴 405连接, 如图 4B 所示, 半柱形彩色透光板的底部也可采用半园盘与旋转轴 405连接。
这样, 若通过彩色透光板围绕旋转轴 405转动时, 每个彩色透光板可全 部旋转到后面不显示相应的色彩, 或者可全部转动到前面显示该彩色透光板 的全部色彩, 也可以部分在前面显示相应的该彩色透光板的部分色彩。 因此, 每个彩色透光板通过旋转的角度与白色反光板通过各种组合的叠加而形成不 同的彩色显示。
彩色透光板的颜色可根据实际需要任意选择, 不受限制。 以下以颜色为 黄色、 天蓝色或粉色为例对本发明的显示方法进行说明。
如图 3A所示,彩色透光板为 1个, 白色反光板 301本身反光产生白色光, 彩色透光板 302的颜色可为黄色、 天蓝色或粉色, 这样, 白色反光板 301与 黄色、 天蓝色或粉色透光板 302组合叠加将显示与该彩色透光板的颜色相应 的色彩, 即黄色、 天蓝色或粉色。
如图 3B所示, 彩色透光板为 2个, 彩色透光板 302、 303可分别为黄色 和粉色透光板、 黄色和天蓝色透光板、 或者粉色和天蓝色透光板; 其中, 白 色反光板 301 与黄色透光板、 粉色透光板组合叠加显示红色; 白色反光板与 粉色、 天蓝色透光板组合叠加显示蓝色; 白色反光板与黄色、 天蓝色透光板 组合叠加显示縁色。 其中, 上述彩色透光板的位置可互换。
如图 3C所示, 彩色透光板为 3个, 彩色透光板 302、 303、 304可分别为 黄色、粉色和天蓝色,白色反光板 301与黄色、粉色和天蓝色透光板 302、 303、 304组合叠加显示黑色。 其中, 上述彩色透光板的位置可互换。
由上述可知, 通过白色反光板和彩色透光板之间的任意组合、 叠加, 可 产生上述 8种色彩的色彩显示。
另外, 当任何白色反光板和任何一种彩色透光板只有一部分参与组合、 叠加时, 就会显示出上述八种色彩以外的色彩。 例如, 如图 3A所示, 在一个 彩色透光片的情况下, 若该彩色透光板为黄色, 当只有一部分参与叠加时, 所表现出来的色彩是浅黄色, 参与的部分越少, 显示出来的黄色越浅。 如图 3B所示, 在二个彩色透光板的情况下, 若该彩色透光板为黄色和粉色, 当这 两个彩色透光板同时只有一部分参与叠加时, 所表现出来的色彩是浅红色, 参与的部分越少, 显示出来的红色越浅。 如图 3C所示, 在三个彩色透光板的 情况下, 若这三个彩色透光板为黄色、 粉色和天蓝色, 当三个彩色透光板同 时只有一部分参与叠加时, 所表现出来的色彩是浅黑色, 参与的部分越少, 显示出来的黑色越浅。
如图 4A和 4B所示, 当采用上述 3种颜色的 3个彩色透光板且形状采用 半圆柱形时, 可通过手动或外部电机驱动该 3个半圆柱彩色透光板 402、 403、 404绕旋转轴 405转动, 例如, 彩色透光板 402、 403、 404的颜色可分别为黄 色、 天蓝色和粉色。
每个彩色透光板 402、 403、 404旋转到后侧, 不显示相应色彩。 每个彩 色透光板 402、 403、 404旋转到前面, 显示相应全部色彩。 当然, 每个彩色 透光板 402、 403、 404部分旋转到前面而显示相应部分色彩。
例如, 当彩色透光板 402、 403、 404 中的任意一个旋转到前面时, 可显 示该彩色透光板 402、 403、 404的相应色彩, 即黄色、 天蓝色或粉色。
当彩色透光板 402、 403、 404中的任意 2个旋转到前面时, 可显示这 2 个彩色透光板叠加的相应色彩, 即红色、 绿色或蓝色。
当彩色透光板 402、 403、 404全部旋转到前面时, 可显示这 3个彩色透 光板 402、 403、 404叠加的相应色彩, 即黑色。
此外, 每个彩色透光板 402、 403、 404也可旋转不同的角度, 这样, 此 3 个彩色透光板 402、 403、 404与白色反光片 401通过各种组合的叠加而形成 不同的彩色显示。 例如, 在一个彩色透光片的情况下, 若该彩色透光板为黄 色, 当只有一部分参与叠加时, 所表现出来的色彩是浅黄色, 参与的部分越 少, 显示出来的黄色越浅。 在二个彩色透光板的情况下, 若该彩色透光板为 黄色和粉色, 当这两个彩色透光板同时只有一部分参与叠加时, 所表现出来 的色彩是浅红色, 参与的部分越少, 显示出来的红色越浅。 在三个彩色透光 板的情况下, 若这三个彩色透光板为黄色、 粉色和天蓝色, 当三个彩色透光 板同时只有一部分参与叠加时, 所表现出来的色彩是浅黑色, 参与的部分越 少, 显示出来的黑色越浅。

例如, 当彩色透光板 407、 408、 409围绕旋转轴 405分别转动时, 每个 彩色透光板 407、 408、 409 的透明体可以全部在前面不显示相应色彩, 也可 以全部在后面显示相应全部色彩, 还可以部分在后面显示相应部分色彩。 因 此, 彩色透光板 407、 408、 409在分别旋转成不同的角度时与白色反光板 405 通过各种组合的叠加而形成不同的彩色显示。
当彩色透光板 407、 408、 409 的透明体部分全部转到前面时, 可显示白 色反光板 405白色。
当彩色透光板 407、 408、 409 的透明体部分全部转到后面时, 可显示彩 色透光板 407、 408、 409的三个颜色叠加后的黑色。
当彩色透光板 407、 408、 409 中的两个透明体部分全部转到前面时, 而 另一个彩色透光板的透明体部分全部转到后面时, 可显示透明体部分转到后 面的彩色透光板的颜色, 可为黄色、 天蓝色或粉色。
当彩色透光板 407、 408、 409 中的两个透明体部分全部转到后面时, 而 另一个彩色透光板的透明体部分全部转到前面时, 可显示透明体部分全部转 到后面的两个彩色透光板叠加后的颜色, 即红色、 绿色或蓝色。
当彩色透光板 407、 408、 409 中的任何一个、 两个或者三个的透明体部 分上的一部分在前面而一部分在后面时, 可显示白色、 黑色、 黄色、 天蓝色、 粉色、 红色、 绿色和蓝色之外的多种颜色。 比如, 浅黑、 浅黄、 浅红、 浅绿、 浅蓝等等。
上述彩色透光板 407、 408、 409可在手动或外部电机驱动下围绕旋转轴 405进行旋转, 并可根据实际需要控制上述彩色透光板的旋转的角度, 以显示 各种所需要的颜色。
由上述可知, 可通过彩色透光板与白色反光板各种组合的叠加形成不同 的彩色显示, 这种显示方法不需要消耗电能, 并且环保。

此外, 显示屏还可包括发光二极管 703, 如图 7A、 7B所示, 该发光二极 管 703在显示屏幕 701的显示单元 702之间或者四个角上, 从而在显示单元
702点阵上, 又形成了一个发光二极管点阵。
如图 7A所示, 发光二极管 703布置安装于显示单元 702的四个角上。 如图 7B所示, 发光二极管 703布置安装于显示单元 702之间。
其中, 发光二极管 703可以是任何单色管, 也可以是几个单色管组合而 成的单色或彩色发光二极管束, 还可以是单一的七彩发光二极管或七彩发光 二极管束。
发光二极管点阵可以作为整个显示屏幕 701 的照明光源。 发光二极管点 阵可以发出单色光, 也可以配合整个显示屏幕 701 的显示发出相应的各种色 彩的彩色光。 发光二极管点阵也可以是独立于整个显示屏单独发光, 形成一 个独立的发光二极管显示屏, 显示各种单色或彩色的内容。
在图 6A和图 6B、 图 7A和图 7B所示的实施方式中, 显示屏幕 601、 701 由显示屏框架 603、 708支撑。 显示屏幕以及发光二极管点阵 701与控制电路 604、 704相连接, 控制电路 604、 704用来控制发光二极管和显示屏幕。 电源 605、 705通过电路板 604、 704为整个显示屏提供电动力。 计算机 606、 706 通过用来翻译和传递计算机命令给电路板 604、 704的转换电路 607、 707来 连接控制电路 604、 704并向其发出指令, 进而对整个显示屏进行计算机控制 显示。 因此, 显示屏可以在计算机 606、 706控制下显示各种文字、 图案、 动 画和视频。 显示屏以及发光二极管点阵还可以通过电话上网、 无线上网、 无 线传输、 硬盘、 闪存盘、 CD和 D V D盘进行数据传输、 储存和控制。
当采用图 5A和 5B所示的显示单元时, 把第一支撑结构 512和第二支撑 结构 521组合固定在一起, 成为一个整体的显示单元。 多个显示单元一起进 行排列组合而组成一个显示点阵, 从而形成一个透光反光式显示屏。 这样, 将转子 51中的彩色透光板 514、 516、 519上的磁铁条或磁铁棒 513、 515、 518 和转子驱动体 52作为驱动单元。每个显示单元的转子可以在其相应的转子驱 动体的驱动下显示不同的颜色, 因此在整个显示屏上便会显示出不同的文字、 图案和画面。 显示单元的数目可以是大于 1 的任何整数。 显示点阵可以任意 组合。
此外, 还可以把所形成的转子 51和转子驱动体 52分离开来。 转子 51独 立作为一个显示单元, 多个转子 51—起进行排列组合而组成一个显示点阵, 从而形成一个透光反光式显示屏。
这样, 将转子驱动体 52单独作为驱动单元, 这样, 驱动单元可有一个或 多个。可以用一个或者多个转子驱动体组合成矩阵独立地在显示屏后面移动, 到达每一个像素点后时, 发出信号, 相应地驱动这个显示单元的转子来显示 该转子的显示颜色。 当转子驱动体 52在整个显示屏后移动扫描后, 每个显示 单元的转子便都被驱动而显示不同的颜色, 因此在整个显示屏上便会显示出 不同的文字、 图案和画面。
当转子驱动体是一个时, 该个转子驱动体可以任何方式在显示屏幕后进 行扫描, 直到所有的显示单元都被驱动为止。
当转子驱动体是多个时, 这些转子驱动体可以排列为一条线, 也可以排 列为长方形或正方形矩阵的形状。 这些被排列为一条线或者矩阵形状的转子 驱动体可以任何方式在显示屏幕后进行扫描, 直到所有的显示单元都被驱动 为止。
单个转子驱动体或者多个转子驱动体的组合体在扫描移动时, 可以用手 动的方式实现。单个转子驱动体或者多个转子驱动体的组合体在扫描移动时, 也可以用步进电机或者任何电机带动而进行横向和竖向扫描的方式实现。 由上述可知, 通过白色反光板和彩色透光板叠加显示色彩的显示屏, 与 液晶显示装置或 LED显示屏相比, 不需要发光, 因此不消耗电能, 既节能又 环保, 结构简单、 成本低。
