具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动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。
根据本发明总体上的发明构思，提供一种红外触摸屏，包括：透明面板，所述透明面板具有供触摸的表面；红外发射装置，所述红外发射装置配置成发射红外线，所述红外发射装置发射的红外线射入所述透明面板，并在所述透明面板内发生全反射；红外接收装置，所述红外接收装置配置成接收全反射的红外线；和处理器，所述处理器配置成对红外接收装置接收的红外线进行强度分析，判断触摸强度。
另外，在下面的详细描述中,为便于解释,阐述了许多具体的细节以提供对本披露实施例的全面理解。然而明显地，一个或多个实施例在没有这些具体细节的情况下也可以被实施。在其他情况下,公知的结构和装置以图示的方式体现以简化附图。
本发明实施例提供了一种红外触摸屏，如图3-图6所示，包括透明面板10、红外发射装置21、红外接收装置22和处理器23。透明面板10具有供触摸(例如供手指触摸)的表面101。红外发射装置21配置用于发射红外线。如图5所示，由红外发射装置21发射的红外线在透明面板10内发生全反射。红外接收装置22接收经过全反射的红外线。处理器23对红外接收装置22接收的红外线进行强度分析，判断触摸强度。
具体的，如图4、图5所示，以手指的触摸位置为A处为例，由于手指相对于透明面板为光密介质，而空气相对于透明面板为光疏介质，则在手指触摸的位置处红外光从光疏介质进行光密介质，则A处的红外光发生折射，该处的部分红外光被手指吸收。一方面手指的触摸强度越大(即用力越大)手指与透明面板的接触面积越大，手指吸收的红外光越多；另一方面，由于红外光对在透明面板表面发生全反射或折射的介质界面特别敏感，手指的触摸强度越大，手指与透明面板的接触越紧密，手指与透明面板之间的空气就越少，触摸位置处吸收的红外光就越多。而其他位置处的红外光发生全反射，而未被吸收。处理器根据对应的红外接收装置接收的红外光的强度，进而可以确认红外接收装置接收的红外光的减少量，进而可以确定触摸强度。
作为示例，如图3所示，本发明实施例提供的红外触摸屏包括一个红外发射装置21和多个红外接收装置22，一个红外发射装置21用于将多条红外线发射入所述透明面板，多个红外接收装置22分别用于接收红外发射装置21发射的所述多条红外线。作为示例，由该红外发射装置21发射的多条红外线可以沿着各自不同的方向传播。
本发明实施例提供的红外触摸屏，其可以单独使用，也可以与现有的触摸屏结合使用。例如可以在现有的触摸屏(如图1-2所示)上再设置本发明实施例如图3、图4 所示的红外触摸屏，通过本发明实施例提供的红外触摸屏确定触摸强度，再通过现有的触摸屏确定触摸位置。
作为示例，如图3所示，透明面板10为矩形，一个红外发射装置21从透明面板10的拐角位置发射多条红外线，所述多条红外线在所述透明面板10中分别沿着多个方向朝透明面板外周处的多个位置传播。作为示例，所述多个红外接收装置可以分别位于透明面板外周处的所述多个位置。在图3中，多个红外接收装置22分布在与红外发射装置21相对的两侧(即图3页面中的右手侧和下方侧)，以接收红外发射装置21发射的红外线。可选地，红外发射装置21也可以位于透明面板外周处的任一位置(例如位于矩形透明面板的任一侧)。而该红外发射装置21位于拐角处的方案能够获得更大的红外线覆盖面积，更有利于检测不同位置处的触摸强度。
作为示例，如图3所示，该红外发射装置21从透明面板10的拐角位置发射多条红外线，红外发射装置21在所述透明面板中的发光角度大于或等于90°，这样可以使得红外发射装置21发射的红外线完全覆盖整个透明面板，因而可以检测到透明面板上任何位置的触摸强度。
在一示例中，如图4所示，透明面板10为矩形，包括相对的第一侧11和第三侧13，以及相对的第二侧12和第四侧14，透明面板10的第一侧11设置有多个红外发射装置21，透明面板10的第三侧13设置有多个与所述红外发射装置21一一对应的红外接收装置22，其中，位于第一侧11的多个红外发射装置21发射的红外线射入透明面板10，位于第三侧13的多个红外接收装置22接收对应的红外发射装置21发射的红外线。作为示例，位于所述第一侧的多个红外发射装置中的每一个红外发射装置仅沿着一个方向发射红外线。即，一个红外发射装置仅发射一条红外线，对应的红外接收装置仅接收一条红外线，这样红外线可以均匀分布在透明面板上，以检测触摸位置处的触摸强度。
在一示例中，如图6所示，透明面板包括相对的第一侧11和第三侧13，以及相对的第二侧12和第四侧14，第一侧11和第二侧12设置有多个红外发射装置21、第三侧13和第四侧14设置有与红外发射装置21一一对应的红外接收装置22，其中，位于第一侧11和第二侧12的多个红外发射装置21发射的红外线射入透明面板10，位于第三侧13和第四侧14的多个红外接收装置22接收对应的红外发射装置发射的红外线；处理器23对红外接收装置22接收的红外线进行强度分析，还可以用于判断触摸位置。
具体的，如图6所示，红外线横纵交叉，触摸位置为A处，则A处的两条红外光被吸收，对应的两个红外接收装置接收的红外线较弱，则可以根据红外接收装置确定触摸位置A，进而可以实现触摸检测功能。如图6所示的红外触摸屏不仅可以确定触摸强度还可以确定触摸位置，可以用于取代现有的触摸屏。
作为示例，位于所述第二侧的多个红外发射装置中的每一个红外发射装置可以仅沿着一个方向发射红外线。
在一示例中，透明面板可以包括上表面、与上表面相对的下表面以及位于上表面和下表面之间的侧面(例如，第一侧、第二侧、第三侧、第四侧)，红外发射装置和所述红外接收装置可以位于透明面板的上表面和/或下表面；或者，红外发射装置和红外接收装置可以位于透明面板的侧面。具体的，如图5所示，本发明实施例仅以红外发射装置21和红外接收装置22均位于透明面板10的下表面(即如图5中示出的底表面)为例进行说明。
本发明实施例还提供了一种显示设备，包括本发明任一实施例所述的红外触摸屏。当然，显示设备也可以是液晶显示设备或者有机发光二极管显示设备。本发明实施例及附图仅以液晶显示设备为例进行说明，具体的，如图7所示，显示设备可以包括液晶显示屏100和红外触摸屏。所述显示设备可以为液晶显示器、电子纸、OLED(Organic Light-Emitting Diode,有机发光二极管)显示器等显示器件以及包括这些显示器件的电视、数码相机、手机、平板电脑等任何具有显示功能的产品或者部件。
作为示例，如图8所示，显示设备包括对盒的上基板40和下基板30，其中，上基板40包括衬底基板以及形成在衬底基板上的显示结构，例如显示用叠层，衬底基板为透明面板10，红外发射装置21发出的红外光在衬底基板内发生全反射。图8中以液晶显示设备为例，则其还包括位于上基板和下基板之间的液晶50，例如，上基板40可以是彩膜基板，下基板30可以是阵列基板，上基板包括透明面板10以及形成在透明面板10上的彩色膜层以及黑矩阵膜层等。此时，透明面板10可以为彩色膜层的衬底基板，红外发射装置21发射的红外线在透明面板10内发生全反射，这有利于减小显示设备的重量和厚度。
需要说明的是，由于红外线在透明面板内发生全反射是从光密介质(例如玻璃基板)到光疏介质(例如空气)，若在透明面板上还形成有其他显示层结构，则显示层结构相对于透明面板为光疏介质，以使得红外发射装置发射的红外线依然可以在透明面板内发生全反射。
本发明实施例还提供了一种触摸检测方法，应用于本发明任一实施例所述的红外触摸屏，如图9所示，所述触摸检测方法包括：
步骤101、利用红外发射装置将红外线发射入透明面板，并使该红外线在透明面板内发生全反射(例如可以通过调整红外线出射角度使红外线在透明面板与空气的界面上入射角满足全反射条件以保证产生全反射)。
步骤102、利用红外接收装置接收经过全反射的红外线。
步骤103、利用处理器对由红外接收装置接收的红外线进行强度分析，以判断触摸强度。
在一示例中，如图3所示，触摸屏包括一个红外发射装置21和多个红外接收装置22；红外发射装置21发射分别沿着多个方向传播的多条红外线，多个红外接收装置22分别接收由红外发射装置21发射的所述多条红外线。作为示例，如图3所示，透明面板10为矩形，上述步骤101可以包括：由一个红外发射装置21从透明面板10的拐角位置发射分别沿着多个方向传播的多条红外线。而多个红外接收装置22分布在与红外发射装置21相对的两侧，上述步骤102可以包括：利用多个红外接收装置22分别接收红外发射装置21发射的多条红外线。
在一示例中，如图4所示，透明面板10为矩形，包括相对的第一侧11和第三侧13，以及相对的第二侧12和第四侧14，透明面板10的第一侧11设置有多个红外发射装置21，透明面板10的第三侧13设置有多个与红外发射装置21一一对应的红外接收装置22，其中，位于第一侧21的多个红外发射装置21发射沿着一个方向传播的红外线；上述步骤101可以包括：由位于第一侧11的多个红外发射装置21将红外线发射入透明面板10；上述步骤102可以包括：利用位于第三侧13的多个红外接收装置22接收由对应的红外发射装置21发射的红外线。即一个红外发射装置发射一条红外线(沿一个方向传播)，对应的红外接收装置接收一条红外线，这样红外线可以均匀分布在透明面板上，以检测触摸位置处的触摸强度。
在一示例中，如图6所示，透明面板10的第一侧11和第二侧12设置有多个红外发射装置21、透明面板10的第三侧13和第四侧14设置有与红外发射装置21一一对应的红外接收装置22；其中，位于第一侧11和第二侧12的多个红外发射装置21发射沿着一个方向传播的红外线；上述步骤101可以包括：利用位于第一侧11和第二侧12的多个红外发射装置21将红外线发射入透明面板10；上述步骤102可以包括：利用位于第三侧13和第四侧14的多个红外接收装置22接收由对应的红外发射装置21发射的红外线；处理器23除去判断触摸强度之外还可以判断触摸位置。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
