具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。
应理解,本申请实施例的技术方案可以应用于各种可以采用触控笔的触控设备或电子设备,例如,手机、平板、二合一平板电脑、笔记本电脑、一体机、电子白板、工控设备等。本申请实施例中的触控设备和电子设备可以为上述各种设备,但本申请实施例对此并不限定。
还应理解,在本申请实施例中,触控笔为可以在触控设备的屏幕上实现输入的设备,本申请实施例对其具体的名称不做限定。另外,本申请实施例也不限定触控笔的形状,也就是说,触控笔的形状不限定为笔的形状。
在本申请实施例中,电子设备可以包括触控笔和触控设备。触控笔也可以作为独立的设备。
在本申请实施例中,触控设备的屏幕上设置有与屏幕上的位置关联的编码图案,触控笔采集触控设备的屏幕上的编码图案的图像,根据采集的图像确定触控笔相对于触控设备屏幕的位置信息。这样,位置信息通过图像采集和图像识别获得,从而不会受干扰(如显示器干扰和触控设备充电的干扰)的影响。
图1示出了本申请实施例的触控笔100的示意图。如图1所示该触控笔100可以包括图像采集模块110和处理器120。
图像采集模块110用于采集触控设备的屏幕上的编码图案的图像,并将该图像传输给处理器120,其中,该编码图案与该屏幕上的位置关联。
处理器120用于根据该图像确定该触控笔相对于该屏幕的位置信息。
具体而言,在本申请实施例中,触控设备的屏幕上设置有与位置关联的编码图案。也就是说,屏幕上不同位置的图案不同。例如,屏幕上每一个像素的位置赋予一个代码,这样,不同区域内的编码图案不同。因此,根据采集的相应区域内的编码图案的图像,可以确定采集相应图像时触控笔的位置。
可选地,可以预先配置屏幕上的不同位置,例如坐标,与不同图案的映射关系,这样,处理器120可以根据采集的图像和该映射关系,确定采集图像时触控笔对应于屏幕上的坐标。
可选地,该图像采集模块110可以为摄像头,但本申请实施例对此并不限定。
可选地,该图像采集模块110可以设置在该触控笔100的笔尖一端。这样图像采集模块的位置与笔尖更接近。
应理解,该图像采集模块110也可以设置在该触控笔100的其他位置。在确定位置信息时将图像采集模块110与笔尖的相对位置考虑进去即可。
可选地,该处理器120可以为微控制单元(Microcontroller Unit,MCU),但本申请实施例对此并不限定。
可选地,触控设备的屏幕包括编码层,该编码图案为在该编码层上蚀刻的与位置关联的图案。
可选地,在本申请一个实施例中,该编码层复用该显式模组中的下玻璃基板上的氧化铟锡(Indium Tin Oxides,ITO)层或者显式模组中的上玻璃基板上的ITO层或者触控层中的ITO层。例如,显示模组可以是液晶显示器(Liquid Crystal Display,LCD)模组或有机发光二极管(organic light-emitting diode,OLED)模组,本申请实施例对此并不限定。
具体而言,在本申请实施例中,编码层可以复用屏幕中的ITO层,在该ITO层上蚀刻特定的编码图案。复用的ITO层可以是下玻璃基板上的ITO层(图2a),也可以是上玻璃基板上的ITO层(图2b),还可以是触控层中的 ITO层(图2c),但本申请实施例对此并不限定。
可选地,在本申请一个实施例中,该编码层复用该屏幕的偏光片下的透明层。
如图2d所示,可以在屏幕的偏光片下镀一层透明材料作为编码层。
可选地,在本申请一个实施例中,该编码层为该屏幕上新增的薄膜或玻璃上的透明层。
如图2e所示,可以在屏幕上面增加一层薄膜(film)或玻璃(glass),并镀一层透明材料作为编码层。
应理解,以上只是举例,编码层还可以设置在屏幕的其他层或新增层,本申请实施例对此并不限定。
应理解,上述ITO也可以变换为其他替代物,例如金属网格(metal mesh)、纳米银等材料,这些变换也应涵盖在本申请的保护范围之内。
可选地,可选地,该编码图案的最小图案单位可以为像素点,即,图案的变化可以是像素级别的。
可选地,该编码图案可以包括多个单元,每个单元可以为一个码。
例如,如图2f所示,编码图案可以包括14个码,这样最大坐标分辨率为214,即4096,因此可以支持4K分辨率的屏幕。如果分辨率更高,可采用大于14个码的方案,如15个码。作为一个示例,上述码可以采用二维码,但本申请实施例对此并不限定。
在本申请实施例中,图像采集模块110采集触控设备的屏幕上的编码图案的图像,并将该图像传输给处理器120;处理器120根据该图像确定该触控笔100相对于该屏幕的位置信息。这样,该位置信息可以通过图像采集和图像识别获得,从而不会受干扰的影响。
可选地,如图3所示,在本申请一个实施例中,该触控笔100还可以包括:
无线通信模块130,用于将该位置信息发送给该触控设备。
无线通信模块130将该位置信息发送给该触控设备,该触控设备可以进一步在各种应用中使用该位置信息。
可选地,无线通信模块130可以为蓝牙模块,但本申请实施例对此并不限定,无线通信模块130也可以为其他可以实现与触控设备通信的模块。
可选地,如图4所示,在本申请一个实施例中,该触控笔100还可以包 括:
压力检测模块140,用于检测该触控笔100相对于该屏幕的压力信息。
该压力检测模块140可以检测压力。例如,在触控笔100触摸屏幕时,该压力检测模块140可以检测到压力。
可选地,在本申请一个实施例中,该无线通信模块130还用于将该压力信息发送给该触控设备。在这种情况下,该触控设备可以根据该位置信息和该压力信息确定触控信息。
具体而言,该触控设备根据该压力信息,确定触控笔100触摸了屏幕,再结合位置信息,可以确定触控笔100触摸屏幕的位置,例如坐标。进一步地,该压力信息可以包括压力的大小,这样触控设备可以获知触摸位置和触摸力度,从而可以将其在各种应用中使用。
应理解,该触控设备也可以自行获取该压力信息,例如通过该触控设备上设置的压力检测模块检测该压力信息,再结合上述位置信息使用。
可选地,在本申请另一个实施例中,该图像采集模块110用于在该压力检测模块140检测到该触控笔相对于该屏幕的压力时采集该触控设备的屏幕的图像。
具体而言,在本实施例中,该压力检测模块140检测到压力时,可以通知该图像采集模块110采集该触控设备的屏幕的图像;或者通知处理器120检测到了压力,处理器120再通知该图像采集模块110采集该触控设备的屏幕的图像。在这种情况下,采集的图像为触控笔100触摸屏幕时的图像。这样,触控设备在接收到该位置信息后,即可确定触控笔100触摸屏幕的位置。
可选地,在本申请另一个实施例中,该无线通信模块130用于将该压力检测模块140检测到该触控笔相对于该屏幕的压力时的该位置信息发送给该触控设备。
具体而言,在本实施例中,该压力检测模块140检测到压力时,通知该无线通信模块130;或者通知该处理器120,该处理器120再通知该无线通信模块130。有压力时的位置信息为触控笔100触摸屏幕时的位置信息。该无线通信模块130将此时的位置信息发送给该触控设备。这样,触控设备在接收到该位置信息后,即可确定触控笔100触摸屏幕的位置。
可选地,如图5所示,在本申请一个实施例中,该触控笔100还可以包括:
充电模块150,用于对该触控笔100进行充电。
在使用触控笔时,例如书写时,图像采集模块110(如摄像头)需要一直开着,所以功耗较大。因此,可以通过充电模块150对触控笔100进行充电。可选地,充电模块150可以为快速充电模块。
应理解,该触控笔100也可以采用非充电电源,例如,电池,本申请实施例对此并不限定。
本申请实施例的触控笔,通过采集触控设备的屏幕上的与位置关联的编码图案的图像,根据该图像确定该触控笔相对于该屏幕的位置信息,这样,该位置信息的获取仅通过图像采集和图像识别,不需要电信号的测量,从而能够降低干扰的影响。
