Description

红外触控屏、其触控侦测方法及显示装置 技术领域
本发明的实施例涉及一种红外触控屏、其触控侦测方法及显示装置。
背景技术
目前，红外触控屏由于具有不受电流、电压和静电干扰，适宜恶劣的环境条件的优点，受到了广泛应用。
现有的红外触控屏是利用X、Y方向上密布的红外线矩阵来检测并定位用户的触摸，该红外触控屏包括显示器件，在显示器件的任意相邻两侧边排布的红外发射器和除设置红外发射器之外的其他相邻两侧边排布的红外接收器，形成横竖交叉的红外线矩阵。用户在触摸显示器件时，手指就会挡住经过该发生触控位置的横竖两条红线，因而可以判断出触摸点在显示器件的位置。
对于现有的红外触控屏，若要达到较高的分辨率，必须要同时增加红外发射器和红外接收器的数量，这样就增大了红外触控屏的整体体积，因此现有的红外触控屏的体积受制于红外发射器和红外接收器的数量，从而限制了红外触控屏的分辨率，提高了制造成本以及限制了其在较大尺寸的显示装置中的应用。
发明内容
本发明的实施例提供一种红外触控屏、其触控侦测方法及显示装置，红外发射器的数量能够减少，且能够提高分辨率、实现精确的触控操作以及有效降低制作成本。
一方面，本发明的实施例提供了一种红外触控屏，包括：显示器件；红外发射器和第一红外接收器，设置在所述显示器件的显示面的任一侧边上，且所述红外发射器发射呈散射状且覆盖所述显示器件出光面的多条红外线；以及多个第二红外接收器，间隔设置在所述显示器件的显示面的除设置所述红外发射器之外的其他侧边上且与所述多条红外线一一对应，其中，所述第 一红外接收器侦测所述红外发射器发射的红外线中被触控位置所反射的红外线。
另一方面，本发明的实施例还提供了一种显示装置，包括本发明实施例提供的上述红外触控屏。
再一方面，本发明的实施例还提供了一种本发明实施例提供的上述红外触控屏的触控侦测方法，包括：控制所述红外发射器发射呈散射状且覆盖所述显示器件出光面的多条红外线；接收所述第一红外接收器和所述多个第二红外接收器侦测的红外信号；以及根据所述第一红外接收器和所述多个第二红外接收器侦测的红外信号确定触控位置的坐标。
附图说明
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涉及本发明的一些实施例，而非对本发明的限制。
图1为本发明实施例提供的红外触控屏的侧视图；
图2为本发明实施例提供的红外触控屏的正视图；以及
图3为图2沿A-A’方向的剖面结构示意图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
下面结合附图，对本发明实施例提供的红外触控屏、其触控侦测方法及显示装置的示例性实施方式进行说明。
其中，附图中各器件的大小和形状不反映红外触控屏的真实比例，目的只是示意说明本发明实施例的内容。
本发明实施例提供了一种红外触控屏，如图1和图2所示，包括：显示器件100，在显示器件100的出光面的任一侧边上设置的一对红外发射器200 和第一红外接收器300；其中，红外发射器200发射呈散射状且覆盖显示器件100出光面的多条红外线，第一红外接收器300侦测红外发射器200发射的红外线中被发生触控位置所反射的红外线，由图1和图2可见，红外发射器200向除设置所述红外发射器200的显示器件的出光面的侧边之外的三个侧边均发射红外线。
该红外触控屏还包括：在显示器件100的除设置红外发射器200之外的其他侧边上间隔设置且与红外线一一对应的多个第二红外接收器400，如图2所示，多个第二红外接收器400的每个在侧边上的位置与红外发射器200发射的多条红外线之一照射到对应侧边上的位置相同。
在本发明实施例提供的上述红外触控屏中，在显示器件100的显示面的任一侧边上只采用一个可以发射呈散射状且覆盖显示器件100出光面的多条红外线的红外发射器200，以及一个可以侦测红外发射器200发射的红外线中被发生触控位置所反射的红外线的第一红外接收器300，这样不仅可以使红外触控屏提高分辨率，实现精确的触控操作，还可以有效降低制作成本，且适用于较大尺寸的显示装置。
示例性地，在本发明实施例提供的上述红外触控屏中，为了能够使第一红外接收器300侦测到红外发射器200发射的红外线中被触控位置所反射的红外线，如图3所示，在显示器件的出光方向上，该红外发射器200一般位于第一红外接收器300的上方，并且，该红外发射器200与第一红外接收器300之间一般具有设定的间距H，这样不但可以保证第一红外接收器300能侦测到红外发射器200发射的红外线中被触控位置所反射的红外线，而且根据红外发射器200与第一红外接收器300之间的设定间距H，以及第一红外接收器300侦测的红外线信号，可以进一步计算触控位置P到第一红外接收器300的距离D。
示例性地，在本发明实施例提供的上述红外触控屏中，为了能够使红外发射器200更容易发射出覆盖整个显示器件100出光面的多条红外线，如图1和图2所示，该红外发射器200与第一红外接收器300一般同时可以位于显示器件100的任一侧边的中心位置O。
例如，在本发明实施例提供的上述红外触控屏中，根据用户对红外触控屏的操作习惯，红外发射器200发射的红外线中被用户触摸的位置所反射的 红外线容易射向显示器件100的底边，为了能够使第一红外接收器300更容易侦测到红外发射器200发射的红外线中被触控位置所反射的红外线，如图1和图2所示，可以将红外发射器200与第一红外接收器300设置于显示器件100的底边。
示例性地，在本发明实施例提供的上述红外触控屏中，为了能够使多个第二红外接收器400的每个可以更好地侦测到红外发射器200发射的红外线，并且可以根据未侦测到红外信号的第二红外接收器400所在位置，更准确地判断发生触控的红外线路径，如图2所示，该红外发射器200发射的多条红外线在显示器件100的出光面一般是分布均匀的；并且，第二红外接收器400在显示器件100的除设置红外发射器200之外的其他侧边上也是均匀地分布。
示例性地，在本发明实施例提供的上述红外触控屏中，还可以包括：用于确定在显示器件100出光面的触控位置的坐标的信号处理芯片，该信号处理芯片分别与第一红外接收器300和多个第二红外接收器400相连。
示例性地，在本发明实施例提供的上述红外触控屏中，为了能够确定在显示器件100出光面的触控位置的坐标，该信号处理芯片可以包括以下四个单元：
用于接收第一红外接收器300和各第二红外接收器400侦测的红外信号的信号接收单元；
示例性地，如图1所示，一般在未发生触控时，即没有用户的手指或其他物件接近显示器件100时，各第二红外接收器400会侦测到红外发射器200发射的呈散射状且覆盖显示器件100出光侧的与第二红外接收器400一一对应的全部的红外线，此时，该信号接收单元可以接收到各第二红外接收器400侦测的红外信号；如图2所示，在发生触控时，即用户的手指或其他物件接近显示器件100时，在触控位置处会阻断红外发射器200发射的红外线，因此，各第二红外接收器400中会存在未侦测到红外信号的第二红外接收器，而被阻断的红外线会发生反射，第一红外接收器300会侦测到被触控位置，例如，触控物体，所反射的红外线，此时，该信号接收单元可以接收到第一红外接收器300侦测的红外信号，而接收不到在第二红外接收器400中未侦测到红外信号的第二红外接收器所在位置的红外信号；
用于根据各第二红外接收器400中未侦测到红外信号的第二红外接收器 所在位置，确定发生触控的红外线路径的第一确定单元；
示例性地，由于信号接收单元接收不到在各第二红外接收器400中未侦测到红外信号的第二红外接收器所在位置的红外信号，第一确定单元根据该第二红外接收器所在位置，可以确定发生触控的红外线路径；
用于根据第一红外接收器300接收到的红外信号与显示器件100的显示面的夹角以及第一红外接收器300和红外发射器200之间的距离H，计算触控位置P到第一红外接收器300的距离D的第二确定单元；
示例性地，如图3所示，该第二确定单元可以检测到第一红外接收器300接收到的红外信号与显示器件100的显示面的夹角，而第一红外接收器300和红外发射器200之间的距离H是依照实际情况设定好的，即H是固定值，根据公式D＝H·cotα可以计算触控位置P到第一红外接收器300的距离D；
用于根据计算出的触控位置P到第一红外接收器300的距离D以及确定出的发生触控的红外线路径，确定出触控位置P的坐标的坐标确定单元；
示例性地，该坐标确定单元可以根据第二确定单元中计算出的触控位置P到第一红外接收器300的距离D，以及第一确定单元中确定出的发生触控的红外线路径，来进一步确定出触控位置P的坐标。
基于同一发明构思，本发明实施例还提供了一种本发明实施例提供的上述红外触控屏的触控侦测方法，由于该方法解决问题的原理与前述一种红外触控屏相似，因此该方法的实施可以参见红外触控屏的实施，重复之处不再赘述。
示例性地，本发明实施例提供的红外触控屏的触控侦测方法，包括以下步骤：
S40、控制所述红外发射器发射呈散射状且覆盖所述显示器件出光面的多条红外线；
S41、接收所述第一红外接收器和所述多个第二红外接收器侦测的红外信号；以及
S42、根据所述第一红外接收器和所述多个第二红外接收器侦测的红外信号确定触控位置的坐标。
其中S42可以包括：
S401、根据各第二红外接收器中未侦测到红外信号的第二红外接收器所 在位置，确定发生触控的红外线路径；
S402、根据第一红外接收器接收到的红外信号与显示器件的显示面的夹角以及第一红外接收器和红外发射器之间的距离，计算触控位置到第一红外接收器的距离；
S403、根据计算出的触控位置到第一红外接收器的距离以及确定出的发生触控的红外线路径，确定出触控位置的坐标。
下面以一个实例详细的说明本发明实施例提供的红外触控屏的触控侦测方法，步骤如下：
1、控制红外发射器发射呈散射状且覆盖所述显示器件出光面的多条红外线；
2、接收第一红外接收器和各第二红外接收器侦测的红外信号；示例性地，如图2所示，在未发生触控时，各第二红外接收器400均会侦测到红外发射器200发射的呈散射状且覆盖显示器件100出光面的多条与第二红外接收器400一一对应的全部的红外线，此时，通过信号接收单元接收各第二红外接收器400侦测的红外信号；在发生触控时，在触控位置处红外发射器200发射的红外线会被阻断，因此，各第二红外接收器400中会存在未侦测到红外信号的第二红外接收器，而被阻断的红外线会发生反射，第一红外接收器300会侦测到被触控位置所反射的红外线，此时，通过信号接收单元来接收第一红外接收器300侦测的红外信号；
3、根据各第二红外接收器中未侦测到红外信号的第二红外接收器所在位置，确定发生触控的红外线路径；示例性地，如图2所示，由于上述信号接收单元接收不到在各第二红外接收器400中未侦测到红外信号的第二红外接收器的红外信号，通过第一确定单元根据该第二红外接收器所在位置，来确定发生触控的红外线路径；
4、根据第一红外接收器接收到的红外信号与显示器件显示面的夹角以及第一红外接收器和红外发射器之间的距离，计算触控位置到第一红外接收器的距离；示例性地，如图3所示，通过第二确定单元检测到第一红外接收器300接收到的红外信号与显示器件100的显示面的夹角，而第一红外接收器300和红外发射器200之间的距离H是依照实际情况设定好的，即H是固定值，根据公式D＝H·cotα就可以计算出触控位置P到第一红外接收器300的 距离D；
5、根据计算出的触控位置到第一红外接收器的距离以及确定出的发生触控的红外线路径，确定出触控位置的坐标；示例性地，如图3所示，通过坐标确定单元根据上述第二确定单元中计算出的触控位置P到第一红外接收器300的距离D，以及上述第一确定单元中确定出的发生触控的红外线路径，来确定出触控位置P的坐标。
至此，经过上述步骤1至5确定出本发明实施例提供的上述红外触控屏的触控位置的坐标。
基于同一发明构思，本发明实施例还提供了一种显示装置，包括本发明实施例提供的上述红外触控屏，该显示装置可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。对于该显示装置的其它必不可少的组成部分均为本领域的普通技术人员应该理解具有的，在此不做赘述，也不应作为对本发明的限制。该显示装置的实施可以参见上述红外触控屏的实施例，重复之处不再赘述。
本发明实施例提供的一种红外触控屏、其触控侦测方法及显示装置，该红外触控屏包括显示器件，在显示器件的任一侧边上设置的红外发射器和第一红外接收器；其中，红外发射器发射呈散射状且覆盖显示器件出光侧的多条红外线，第一红外接收器侦测红外发射器发射的红外线中被触控位置所反射的红外线；还包括在显示器件的除设置红外发射器之外的其他侧边上设置且与红外线一一对应的第二红外接收器，每个第二红外接收器在侧边上的位置与红外发射器发射的多条红外线之一照射到对应侧边上的位置相同，本发明实施例提供的上述红外触控屏只采用一个红外发射器，不仅可以提高分辨率，实现精确的触控操作，还可以有效降低制作成本，以及适用于较大尺寸的显示装置。
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。
本申请要求于2014年12月4日递交的中国专利申请第201410736587.2号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
