本发明的实施例涉及触控显示技术领域，尤其涉及一种显示基板、显示装置及遥控系统。
背景技术
随着平板液晶显示器越来越迅速的发展，具有触控功能的平板液晶显示器已经逐渐成为主流的平板显示器。
目前，实现触控功能一般通过触控显示面板(Touch Panel)来实现，现有技术中的触控显示面板包括两层具有显示功能的面板，分别是CF(Color Filter，彩色滤光片)基板和薄膜晶体管基板；并且都需要实物(手指、触摸笔等)接触触控面板来实现对设备的操控。现有技术中，该类触控方法的基本原理是通过实物压触或遮挡触控面板表面，带来的变形引起光线、电容或电阻的变动，实现对受压触区域的定位，并将不同的压触动作(如单击、双击、滑动)定义成不同的操作来完成一定控制操作。现有技术中的这种触控技术能够准确的判断触控点的位置，准确识别用户操作从而做出响应，但是这种触控技术只能用于与人距离较近的手持设备，如果设备及其触屏离人有一定距离，如带有触屏的电视机，那么人手不能触碰到触屏，这种触控技术不能对一定距离外的显示设备上的任意区域进行精确触控。而常规的遥控装置及方法则需要非常复杂的按键操作，而且有一些需求也无法用按键来实现，即，现有的遥控装置及方法无法给用户带来触控的感觉。

所述坐标寄存器22，其中存储有每一个光识别结构的坐标，用于根据光识别结构输出的电压信号确定并输出光束照射位置的坐标信息并输出给信息处理电路；
所述信息处理电路23，用于根据坐标寄存器输出的坐标信息而判断用户的操作指令，实现对应的操作，并输出显示信号驱动所述显示装置进行显示。
该显示装置中，所述光识别结构接收预设光束的照射时，产生电压信号，并通过信号线将所述电压信号传输给所述坐标寄存器，由于所述坐标寄存器中存储有每一个光识别结构的坐标，所述坐标寄存器可以根据光识别结构输出的电压信号确定并输出光束照射位置的坐标信息，并将所述坐标信息输出给信息处理电路，所述信息处理电路则用于根据坐标寄存器输出的坐标信息而判断用户的操作指令，实现对应的操作，并输出显示信号驱动所述显示装置进行显示，从而实现对一定距离外的显示设备上的任意区域进行精确触控。
本发明实施例三提供了一种遥控系统，所述系统包括上述的显示装置和遥控终端：
所述遥控终端用于向所述显示装置发射预定光束，以向所述显示装置发出操作指令。
所述遥控系统中，通过所述遥控终端向显示装置发射预定光束，所述显示装置中的光识别结构接收预设光束的照射时，产生电压信号，并通过信号线将所述电压信号传输给所述坐标寄存器，由于所述坐标寄存器中存储有每一个光识别结构的坐标，所述坐标寄存器可以根据光识别结构输出的电压信号确定并输出光束照射位置的坐标信息，并将所述坐标信息输出给信息处理电路，所述信息处理电路则用于根据坐标寄存器输出的坐标信息而判断用户的操作指令，实现对应的操作，并输出显示信号驱动所述显示装置进行显示，从而实现对一定距离外的显示设备上的任意区域进行精确触控。
进一步的，所述遥控终端包括用于进行定位的定位激光器和用于进行操作的操控激光器，所述定位激光器和操控激光器的光斑重合，并且所述定位激光器的光波频率小于所述操控激光器的光波频率，使得来自定位激光器的光束照射到光识别结构时光识别结构不产生电压信号，而来自所述操控激光器的光束照射到光识别结构时光识别结构产生电压信号。
根据一个实施例，所述定位激光器发射可见光，所述操控激光器发射不可见光。
一般的，所述定位激光器可选用光波频率比较小的红光或绿光，以便操作者可以识别光束照射到屏幕上的位置；所述操控激光器选用光波频率较大的蓝光或其它光波频率更高的不可见光如紫外光，操作激光器中光束的光波频率较大，光子发生跃迁时产生的激发能较大，与之配合的将所述太阳能电池设计成需要高频的蓝光或其它光波频率更高的不可见光才能激发，以实现远程精确触控的功能。
利用所述遥控终端进行操控时，所述定位的定位激光器长时间点亮，用户可以根据所述定位激光器的光斑确定当前光斑在平面上的位置，以便通过所述操控激光器实现各种操作动作；并且，由于所述定位激光器的光波频率小于所述操控定器的光波频率，所述定位激光器出射的光束不足以使光识别结构产生电压信号，只有操控激光器出射的光束可以使光识别结构产生电压信号并提供给外电路，因此所述定位激光器的光波频率小于所述操控定器的光波频率时可避免所述定位激光器中的出射光束对操作精确度造成影响，避免产生误操作。
基于同一发明构思，本发明实施例还提供了一种遥控方法，具体包括以下步骤：
显示装置接收遥控终端向其显示面板的任意区域发射的预设光束时，确定接收到光束的区域的位置信息；
当显示装置接收到遥控终端向其发出的操作指令时，根据该操作指令执行相应的操作。
其中，所述显示装置接收遥控终端向其显示面板的任意区域发射的预设光束时，确定接收到光束的区域的位置信息，具体包括：
光识别结构接收遥控终端向其发射的预设光束时，产生电压信号并通过信号线传输给坐标寄存器；
所述坐标寄存器根据所述电压信号以及其内部存储的每一光识别结构的 坐标，找出产生所述电压信号的光识别结构对应的坐标。
所述当显示装置接收到遥控终端向其发出的操作指令时，根据该操作指令执行相应的操作，具体包括：
所述信息处理电路根据坐标寄存器输出的坐标信息而判断用户的操作指令，实现对应的操作，并输出显示信号驱动所述显示装置进行显示。
进一步的，所述操作指令包括类似于在触摸屏终端上可以发出的任何操作指令，比如：单击活动区域、双击活动区域、长按活动区域、以活动区域为起始位置的向各个方向的滑动操作等；显示设备根据上述操作指令执行对应的操作，比如：双击图标则打开相应的应用、从右向左滑动则翻页、从下到上滑动则放大被滑动覆盖的区域等。
下面以一个具体的实施例说明本发明提供的遥控方法。如图6所示，安装了智能操作系统的大屏幕电视机601具有光识别结构，其匹配的遥控器602发出预设的光束能够被电视机的光感传感器识别和接收，遥控器和电视机之间通过无线技术实现连接(类似于电脑和鼠标的连接)，遥控器通过此连接向电视机发送操作指令。
使用该遥控器远距离光线遥控电视机的方法步骤如下：
第一步、打开电视，屏幕显示出各种图标，比如“电视节目”、“音乐”、“图片”等等，如图6所示；
第二步、打开遥控器光线发射器开关603，遥控器的顶端发射器604中的定位激光器发射发出红色的可见光(图中实线所示)和操控激光器发出的高频的不可见光(图中虚线所示)，照射在电视机屏幕上，如图7所示；
第三步、电视机内部被光线照射到的光识别结构接收到不可见光，产生电压信号并通过信号线(X轴、Y轴)传递给电视机的信息处理电路，并通过定位激光器照射的光斑让用户知道遥控器指向电视机屏幕上的位置。比如，光线照射到“音乐”的图标上，“音乐”图标所在坐标被传递给电视机信息处理电路，信息处理电路认为音乐图标进入激活状态，如图8所示；
第四步、用户点击操作确认键605，相当于对“音乐”图标进行了点击操作(相当于点击鼠标的左键，或智能手机用户用手指触控手机屏幕)，进入音乐库，音乐库里面有很多歌曲图标，分很多版面显示(从左到右，1版、2版、3版显示，每次只显示一版)，如图9所示；
第五步、用户按住操作确认键605不放，遥控器的操控激光器向电视机屏幕发出的不可见光，并使该不可见光从右到左滑过，如图10所示。当前显示屏幕(假设为1版)上的图像从右向左移动并消失，屏幕显示2版，其过程与用手滑动智能手机相似，如图11所示。
综上所述，本发明实施例提供了一种显示基板、显示装置及遥控系统；其中，所述显示基板中设置有至少一个位于所述显示基板的非显示区域的光识别结构；通过将所述光识别结构设置在所述显示基板的非显示区域，感知预定光束的照射并产生电压信号通过与之连接的信号线传输给外电路，使得外电路根据所述电压信号确定光束照射的位置，实现对一定距离外的显示设备上的任意区域进行精确触控；同时还可以增大像素的开口率；同时，将所述光识别结构形成在所述衬底基板上，有利于提高光的透过率，简化显示面板的结构，增大显示面板的亮度，提高显示质量。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
