为了更清楚地说明本发明实施例的技术方案， 下面将对实施例的附图作 简单地介绍， 显而易见地， 下面描述中的附图仅仅是本发明的一些实施例， 而非对本发明的限制。
图 1为本发明实施例的显示系统的一结构示意图；
图 2 为本发明实施例的光束发射装置的一结构示意图；
图 3为本发明实施例的显示装置的一结构透视图。 具体实施方式
下面结合附图和实施例， 对本发明的具体实施例作进一步详细描述。 如图 1所示为本发明实施例的显示系统 100的结构示意图。 该显示系统 100包括： 光束发射装置 101和显示装置 102。该显示装置 102包括一显示区 域 1021和非显示用的周边区域 1022。 该光束发射装置 101能够发射第一光 束和第二光束。该第一光束为定位光束，用于对该显示区域 1021上的需要触 控的位置（点）进行定位， 即用于标示该显示区域 1021上的输入位置， 由于 定位需要人眼看见， 因此该第一光束为可见光。 该第二光束为触发光束， 用 于在该显示区域 1021上执行触控操作， 即，用于确认该第一光束标示的输入 位置。 该第二光束与该第一光束不同， 该不同之处可以是强度不同、 波长不 同或者光束横截面尺寸不同等。
为了能够感测到该光束发射装置 101发射的第二光束， 以及在感测到第 二光束后执行相应的操作， 该显示装置 102还包括： 分布在该显示区域 1021 内的感光器件（图未示出）及耦接于该感光器件的处理器件（图未示出） 。 该感光器件用于感测投射在该显示区域 1021 上的第二光束， 并得到感测结 果。 该处理器件用于根据该感测结果， 确定该第二光束在该显示区域 1021 上的投射位置， 并根据该第二光束的投射位置执行相应的操作。
该感光器件可以为多种类型的感光器件， 例如可以为光敏二极管、 感光 CMOS ( Complementary Metal Oxide Semiconductor, 互^卜金属 匕物半导体 ) 或光导 TFT ( Thin Film Transistor , 薄膜场效应晶体管）等。 该显示装置 102 可以包括多个感光器件，该多个感光器件分布在该显示区域 1021内，每一该 感光器件均可以对应一地址信息， 当任一感光器件感测到该光束发射装置 101 发射的第二光束时， 可以将自身的地址信息作为该感测结果发送给该处 理器件， 该处理器件根据该感光器件的地址信息， 确定该第二光束在该显示 区域 1021上的投射位置， 从而执行相应的操作。
该光束发射装置 101可以是一单独的物理设备， 也可以集成在其他物理 设备中， 例如， 集成在电视遥控器中或者手机中等。
用户可以使用该光束发射装置 101 发射第二光束， 实现对该显示区域 1021上的点的确定操作， 类似于鼠标的点击操作， 或者， 实现在该显示区域 1021上的类似手写或姿势的操作， 或者， 实现类似鼠标拖动光标的操作等。 这些操作或操作模式例如可预先设定， 存储在控制器之中。
该光束发射装置 101 可以通过多种方式控制第一光束和第二光束的发 射， 下面将举例进行说明。
如图 2所示， 该光束发射装置 101的示例包括： 本体 1011和发光组件 1012, 当该光束发射装置 101是单独的一个物理设备时，该本体 1011可以为 多种形状而不限于图中示出的形状， 例如为笔状、 圓柱体状等， 当该光束发 射装置 101集成在其他物理设备中时， 例如集成在电视遥控器中时， 该本体 1011即是该电视遥控器的本体。 该发光组件 1012设置于该本体 1011上， 用 于发射该第一光束和该第二光束。该发光组件 1012可以是发光二极管（ LED ) 等发光器件。
为了控制该第一光束和该第二光束的发射， 该光束发射装置 101还可以 包括一双阶按钮 1013和一控制组件（图未示出 ) , 该双阶按钮 1013设置于 该本体 1011上， 如图 2中所示该双阶按钮 1013设置于该本体 1011的一侧。 该双阶按钮 1013 的一种实现方式能够在不同大小的按压力的作用下下降至 第一高度或第二高度， 该第二高度小于该第一高度。 该控制组件设置于该本 体 1011中，与该双阶按钮 1013和该发光组件 1012连接，用于检测该双阶按 钮 1013的高度， 当检测到该双阶按钮 1013被按压至第一高度时， 控制该发 光组件 1012发射该第一光束， 当检测到该双阶按钮 1013被按压至第二高度 时， 控制该发光组件 1012发射该第二光束。
上述双阶按钮 1013的控制方式可类似于数码相机的快门轻按聚焦、重按 拍照的控制模式。 用户可以轻按该双阶按钮 1013 , 使该双阶按钮 1013高度 下降至该第一高度，当该控制组件检测到双阶按钮 1013高度下降至该第一高 度时， 控制该发光组件 1012发射该第一光束， 对该显示区域 1021上的需要 触控的点进行定位。 在完成定位后， 用户可以重按该双阶按钮 1013 , 使该双 阶按钮 1013的高度下降至该第二高度， 该控制组件检测到该双阶按钮 1013 的高度下降至该第二高度时，控制该发光组件 1012发射该第二光束，对上述 定位的点执行触控操作。
当然， 该光束发射装置 101还可以釆用其他方式控制该第一光束和该第 二光束的发射， 例如， 设置两个按钮（第一按钮和第二按钮） ， 按压第一按 钮发射该第一光束， 按压第二按钮发射第二光束。
或者， 还可以在该光束发射装置 101上设置一滑动拨块和一滑动轨道， 将该滑动拨块从滑动轨道的初始位置滑动到第一位置时， 发射该第一光束， 将该滑动拨块从第一位置滑动到第二位置时， 发射该第二光束。
当然， 该光束发射装置 101还可以釆用其他任何合适的结构， 以控制该 第一光束和该第二光束的发射， 在此不再——列举。
上述多个感光器件用于感测该光束发射装置 101发射的投射在该显示区 域 1021上的第二光束， 该多个感光器件可以均勾分布在显示区域 1021内， 每个感光器件均对应一地址信息，通过检测哪个感光器件感测到该第二光束， 就可以确定该第二光束在该显示区域 1021上的位置。
该感光器件的位置设置通常情况下需要与该显示装置 102上的像素的位 置相关联， 下面将详细进行说明。
本发明的实施例中， 以显示装置为液晶显示装置为例进行说明， 但是本 发明不限于此。 液晶显示装置通常包括： 彩膜基板、 阵列基板和在彩膜基板 和阵列基板之前的液晶层。 该彩膜基板可以包括多个像素， 每一个像素至少 包括第一颜色的亚像素， 该第一颜色的亚像素可以为红色亚像素、 绿色亚像 素、 蓝色亚像素或者其他颜色的亚像素。 红色亚像素仅能够通过红光， 绿色 亚像素仅能够通过绿光， 蓝色亚像素仅能够通过蓝光。
例如， 该第二光束可以设置为能够通过该第一颜色的亚像素的光束， 也 就是说， 该第二光束为第一颜色的光束， 为了能够感测到该第二光束， 该感 光器件可以设置在能够接收到通过该第一颜色的亚像素过滤后的第二光束的 位置上， 例如设置在该阵列基板上的与该第一颜色的亚像素对应的位置上。 另外， 根据定位精度的要求不同， 该感光器件在该显示区域内的分布密 度可以不同。 例如， 当定位精度要求较高时， 每一该第一颜色的亚像素可以 对应一个该感光器件， 当定位精度要求较低时， 每多个该第一颜色的亚像素 可以对应一个该感光器件。
上述实施例中已经提到， 该第一光束与该第二光束不同， 举例来说， 该 第一光束的波长可以与该第二光束的波长不同 （即颜色不同） 。 当该第二光 束为第一颜色的光束时， 该感光器件可以被设置成仅在检测到第一颜色的光 束时，将自身的地址信息传输给该处理器件， 以防止第一光束的干扰。 另夕卜， 为了防止投射在该显示区域 1021上的环境光的干扰，该感光器件可以被设置 成仅在感测预设强度的第一颜色的光束时， 将自身的地址信息作为感测结果 传输给该处理器件， 该预设强度需要明显大于环境光中第一颜色的光束的强 度， 略小于第二光束的强度。
此外， 该第一光束的波长可以与该第二光束的波长相同， 但强度小于该 第二光束的强度， 当该第二光束为第一颜色的光束时， 为了防止第一光束和 环境光中第一颜色的光束的干扰， 该感光器件可以被设置成仅在感测预设强 度的第一颜色的光束时， 将自身的地址信息作为该感测结果传输给该处理器 件， 该预设强度需要同时大于环境光中第一颜色的光束的强度和第一光束的 强度， 小于第二光束的强度。
该第一光束和该第二光束可以为各种类型的光束。 由于激光与其他类型 的光束相比， 具有方向性好、 发散角小等优势， 因此该第一光束和该第二光 束通常釆用激光。 下面分别以该第一光束和该第二光束为不同强度或不同波 长的激光为例， 对本发明的显示系统的具体实施例进行举例说明。
实施例一：
考虑到红光较为容易得到， 本发明的该实施方式中， 光束发射装置的第 一光束和该第二光束均釆用可见光区的红色激光， 该第一光束的强度为第一 强度， 该第二光束的强度为第二强度， 该第二强度大于该第一强度。
请参考图 3 , 彩膜基板上的像素由红（R ) 、 绿（G ) 、 蓝（B )三个颜 色的亚像素组成，感光器件 1022设置在阵列基板的与该红色亚像素对应的位 置上，该感光器件 1022设置成仅在感测到该第二强度的光束时，才将自身的 地址信息传输给处理器件。为了避免第一光束对该感光器件 1022的影响，可 以将第一光束的强度与该第二光束的强度的差距设置得适当地大。
假设光束发射装置包括一双阶按钮， 当轻按双阶按钮时， 触发低强度的 第一光束发射，在显示装置的显示区域上寻找需要操作的 A点。完成定位后， 可以将双阶按钮按压到底时， 触发高强度的第二光束发射， A点对应的感光 器件 1022感测到第二光束，将自身的地址信息传输给处理单元，处理单元根 据该感光器件 1022传输的地址信息，确定该第二光束在该显示区域上的位置 信息， 从而执行相应的触控操作。
上述实施例的优点在于：用于定位和触发的光束使用一种波长的光束（红 色光束） ， 通过调节两个光束的强度， 便可以实现不同的控制， 造价较低。
实施例二：
本发明该实施方式中， 光束发射装置的第一光束釆用可见光区的绿色激 光， 第二光束釆用红色激光， 该第二光束可以为可见光，也可以为不可见光。
同样的， 以彩膜基板上的像素由红、绿、蓝三个颜色的亚像素组成为例， 该感光器件 1022设置在阵列基板的与该红色亚像素对应的位置上。
假设光束发射装置包括一双阶按钮， 当轻按双阶按钮时， 触发绿色激光 (第一光束）发射， 在显示装置的显示区域上寻找需要操作的 A点。 完成定 位后， 可以将双阶按钮按压到底时， 触发红色激光（第二光束）发射， A点 对应的感光器件 1022感测到第二光束， 将自身的地址信息传输给处理单元， 处理单元根据该感光器件 1022传输的地址信息，确定该第二光束在该显示区 域上的位置信息， 从而执行相应的触控操作。
上述实施例的优点在于： 由于使用了两种波长的光束， 可以有效避免定 位光束的干扰， 降低误操作。
本发明的实施例还提供一种光束发射装置， 包括： 本体； 双阶按钮， 设 置于该本体上， 能够在不同大小的按压力的作用下下降至第一高度或第二高 度， 该第二高度小于该第一高度； 发光组件， 设置于该本体上， 用于发射第 一光束和第二光束， 该第一光束为可见光， 该第二光束与该第一光束不同； 控制组件， 设置于该本体中， 与该双阶按钮和该发光组件连接， 用于检测该 双阶按钮的高度， 当检测到该双阶按钮被按压至该第一高度时， 控制该发光 组件发射该第一光束， 当检测到该双阶按钮被按压至该第二高度时， 控制该 发光组件发射该第二光束。
用户可以通过一光束发射装置远距离地向显示装置发射第一光束和第二 光束， 其中， 第一光束用于对显示装置的显示区域上的点进行定位， 第二光 束用于对显示区域上的点进行触控， 显示区域内设置有能够感测第二光束的 感光器件， 根据感光器件的感测结果能够确定第二光束在显示区域上的投射 位置， 并根据第二光束的投射位置执行相应的操作， 例如， 确定操作、 手写 操作、 拖动光标的操作等， 从而对显示装置进行远距离的触控操作。
本发明的实施例还提供一种显示装置， 该显示装置包括： 显示区域、 分 布在该显示区域内的感光器件、 耦接于该感光器件的处理器件， 该感光器件 用于感测投射在该显示区域上的预设光束， 并得到感测结果； 该处理器件用 于根据该感测结果， 确定该预设光束在该显示区域上的投射位置， 并根据该 预设光束的投射位置执行相应的操作。
该显示装置与上述实施例中的显示装置的结构相同， 配合上述实施例中 的光束发射装置使用， 该预设光束即该光束发射装置发射的第二光束。
同时， 该显示装置可为多个或在一个显示装置内可包括多个显示区域也 可以为多个， 通过一个光束发射装置可对多个显示区域内的多个图像进行分 别控制， 使得操控功能更为多样化。
以上该仅是本发明的优选实施例， 应当指出， 对于本技术领域的普通技 术人员来说， 在不脱离本发明原理的前提下， 还可以作出若干改进和润饰， 这些改进和润饰也应视为本发明的保护范围。
