需要说明的是,图1所示的终端设备仅为一种终端设备的举例,本申请并未特别限定,本申请实施例可以应用于手机、平板电脑等电子设备,本申请对此不做限定。
如图1所示,终端设备100可以包括显示屏140。显示屏140可以包括显示面板,显示面板也可以称为显示线路。
可选地,显示屏140还可以包括盖板玻璃(Cover Glass,CG),显示面板可以被盖板玻璃覆盖。进一步地,盖板玻璃的面积可以大于或等于显示面板,盖板玻璃可以与显示面板部分重叠。当盖板玻璃与显示面板部分重叠时,二者重叠的区域可以称为显示屏的显示区域,相应地,二者未重叠的区域可以称为显示屏的非显示区域。
如图1所示,终端设备100还可以包括传感器150,传感器150可以为包括信号发射器和信号探测器的传感器组件,该传感器组件可以为环境光传感器或接近传感器等,其中,信号发射器可以用于向显示屏外发射探测信号,信号探测器可以用于接收探测信号经外部物体反射后形成的反射信号。
接近传感器可以为基于红外光的接近传感器,可以称为光学接近感应传感器,相应地,该基于红外光的接近传感器的信号发射器可以为红外光发射器,用于向显示屏外发射红外光,该基于红外光的接近传感器的信号探测器可以为红外光探测器,用于接收红外光经外部物体反射后形成的反射光。
通常,接近传感器不会裸露在终端设备表面,而是位于显示屏的非显示区域,且配置于盖板玻璃之下。
作为示例而非限定,本申请以基于红外光的接近传感器为例进行描述。为了便于描述,下面将基于红外光的接近传感器统一简称为接近传感器。应理解,本申请实施例中描述的接近传感器仅为传感器组件的一种示例,本申请并未特别限定。
接近传感器可以感应终端设备和物体之间的距离,从而可以使终端设备实现对显示屏的亮灭控制。也就是说,终端设备可以根据接近传感器检测的该终端设备和物体的距离,控制终端设备熄屏或亮屏。通常,接近传感器可以是基于红外光的接近传感器,接近传感器可以由红外光发射器和红外光探测器组成,这里的红外光发射器也可以称为红外光源,红外光探测器也可以称为红外探测器。本申请对于接近传感器的种类不做限定。
终端设备可以具有通信功能,当用户使用该终端设备进行通话时,接近传感器可以采集终端设备和用户耳部的距离,如果终端设备与耳部的距离小于(或等于)预先设置的距离,那么终端设备可以熄灭显示屏,可以降低终端设备的功耗。类似地,当用户结束通话时,接近传感器同样可以采集终端设备和用户耳部的距离,如果终端设备与耳部的距离大于(或等于)预先设置的距离,那么终端设备可以点亮显示屏。
在本申请实施例中,终端设备的显示屏也可以为触摸屏,当用户使用终端设备打电话时,若终端设备与耳部的距离小于(或等于)预设的第一距离,终端设备可以熄灭显示屏,即该终端设备进入接近状态,此时不再接收用户对触摸屏的触摸操作,可以避免因意外触碰显示屏而发生的各种误操作。类似地,如果终端设备与耳部的距离大于(或等于)预设的第二距离,那么终端设备可以点亮显示屏,即该终端设备进入远离状态。
例如,在本申请中,上述预设的第一距离可以为2厘米(cm),上述预设的第二距离可以为5cm,此时,当终端设备与接近物体的距离小于或等于2cm时,该终端设备进入接近状态,当终端设备与接近物体的距离大于或等于5cm时,该终端设备进入远离状态。
若终端设备具有通信功能,当用户使用该终端设备进行通话时,接近传感器可以更加准确地确定物体接近或远离终端设备的显示屏。
当有物体接近终端设备显示屏,或者说接近该盖板玻璃时,红外光发射器发射的光透过盖板玻璃后被接近物体反射,反射后的红外光透过盖板玻璃被红外光探测器接收到。红外光发射器发射的,且经接收物体反射后被红外光探测器接收到的红外光可以称 为接近物体反射光线。在该过程中,红外光发射器发射的光中,会有部分红外光未能透过盖板玻璃,而是经盖板玻璃反射后,被红外光探测器接收到,这部分红外光可以被认为是底噪,且与接近物体反射的红外光相比少得多,可以称为非接近物体反射光线。这里接近终端设备显示屏的物体可以称为接近物体。
当没有物体接近终端设备显示屏时,红外光发射器发射的红外光中,可以认为仅有通过盖板玻璃反射的部分红外光被红外光探测器探测到。即可以理解为,红外探测器接收的红外光中,没有接近物体反射的红外光,只有盖板玻璃反射的红外光。
通常情况下,接近物体与终端设备显示屏的距离越近,红外光探测器捕捉到的红外光能量就越强。因此,通过红外光探测器捕捉到的红外光能量大小(或红外光能量强度),可确定物体与终端设备显示屏的距离,根据该距离可以判断终端设备处于接近状态或远离状态。或者可以说,根据红外光探测器检测到的红外光的能量大小,可以确定终端设备相对于物体是处于接近状态还是远离状态,从而可以控制终端设备熄屏或亮屏。
例如,当红外探测器检测到的红外光的强度大于或等于某个预设的阈值时,可以确定终端设备处于接近状态;当红外探测器检测到的红外光的强度小于某个预设的阈值时,可以确定终端设备处于远离状态。
图2是本申请一个实施例的终端设备的一种示意性结构图。应理解,图2示出的终端设备200仅是一种示例,其中可以包括更多的模块或单元,同时,图2中示出的终端设备200中的各模块或单元的位置仅是示例而非限定。
作为一种示例,图2中的显示屏210可以为图1所示的终端设备100的显示屏140。
如图2所示,终端设备200包括:显示屏210、红外光发射器220和红外光探测器230;所述显示屏210,包括显示区域218和非显示区域216;所述红外光发射器220,位于所述非显示区域216,用于以第一预设辐射强度发射探测信号;所述红外光探测器230,位于所述显示区域218,用于接收反射信号;所述红外光发射器220和所述红外光探测器230之间的距离处于第二预设范围。
应理解,本申请实施例中所述的“显示屏内”中的“内”和“显示屏外”中的“外”,分别与“终端设备内”中的“内”和“终端设备外”中的“外”指示的方位相同。
本申请实施例的终端设备200中,由于红外光探测器230布局在显示区域218,因此可以增大显示屏210的显示区域,从而提高终端设备200的屏占比。
可选地,红外光发射器220和红外光探测器230属于终端设备200的接近传感器,该接近传感器可以为图1所示的终端设备100中的传感器150。
作为本申请实施例一种可能的实现方式,红外光发射器220可以位于所述显示区域218。这样,可以进一步加大显示屏210的显示区域,从而进一步提高终端设备200的屏占比。
在本申请实施例中,图2所示的终端设备200还可以包括听筒201和摄像头202。进一步地,听筒201和摄像头202可以配置在显示屏210内,且位于显示区域218,从而进一步提高终端设备200的屏占比。
通常,红外光发射器220和红外光探测器230可以封装在一起组成接近传感器组件,而在本申请实施例中,可以将红外光发射器220从接近传感器组件中分离出来,以使得红外光探测器230可以设置于显示屏210的显示区域218,从而提高了终端设备200的屏占比。
因为所述红外光探测器230设置于显示屏210的显示区域218,故需要提高所述红外光发射器220的辐射强度,使得所述红外光探测器230可以接收到从所述显示屏外射入所述显示屏的反射信号,从而可以保持所述传感器的功能保持正常。
图3中的接近传感器300为本申请实施例的传感器组件的一个示例,如图3所示,接近传感器300的引脚SCL为时钟总线端口,可以连接终端设备中处理器的引脚SCL;引脚SDA为数据总线端口,可以连接终端设备中处理器的引脚SDA;引脚INT为中断端口,可以连接终端设备中处理器的引脚INT;引脚VDD为工作电压端口,可以连接接近传感器内部的工作电压;引脚GND为接地端口,引脚PGND为保护接地端口;引脚LDR为电流驱动端口,可以连接红外光发射器220的负极(或称为阴极),LEDA表示红外光发射器220的正极(或称为阳极),可以连接终端设备内部电路的供电电压VCC。
其中,红外光探测器230封装在接近传感器300的内部,红外光探测器230的正极接地,红外光探测器230的负极通过其他元器件或模块,与引脚SCL和引脚SDA连接,具体的连接方式可以参考现有技术,本申请不再赘述。
由图3可以看出,红外光发射器220的负极可以在红外光探测器230的外部,且与该红外光探测器230的LDR端口相连,红外光发射器220的正极可以与终端设备内部电路的供电电压VCC相连,此时,可以将红外光发射器220从接近传感器300中分离出来,从而可以实现将红外光发射器220配置在显示屏210的显示区域218、将红外光探测器230配置在显示屏210的非显示区域216。
在本申请实施例的接近传感器300中,可以将红外光发射器220从接近传感器中分离出来,使红外光发射器220在红外光探测器230的外部与该红外光探测器230相连,能够使接近传感器的配置置更加灵活。
需要说明的是,所述红外光探测器230在显示区域的位置需要处于第二预设范围,即所述红外光探测器230需要位于从所述显示屏外射入所述显示屏的反射信号的辐射范围内,这样,所述红外光探测器230才能够接收到所述反射信号。
图4为本申请实施例的终端设备200的一种示例性结构图。如图4所示,终端设备200的显示屏210包括盖板玻璃212和显示面板214,显示面板214配置在盖板玻璃212的下方,显示面板214和盖板玻璃212重叠的区域可以称为显示屏210的显示区域218,显示面板214和盖板玻璃212未重叠的区域可以称为显示屏210的非显示区域216。
红外光发射器220,位于所述非显示区域216,且位于显示屏210内侧,用于以第一预设辐射强度发射探测信号;红外光探测器230,位于所述显示区域218,且位于显示屏210的内侧,用于接收反射信号;所述信号发射器和所述信号探测器之间的距离处于第二预设范围。
可选地,所述第一预设辐射强度可以大于7毫瓦每球面度(mW/sr)。
可选地,所述第二预设范围可以大于2毫米(mm),且小于或等于6mm。
可选地,终端设备200还可以包括电路板260,红外光发射器220和红外光探测器230固定在电路板260上。例如,红外光发射器220和红外光探测器230可以被焊接在电路板260上。
电路板260可以为柔性印制电路板(flexible printed circuit,FPC)或印制电路板(printed circuit board,PCB)。
可选地,终端设备200还可以包括遮光层240,该遮光层240设置于显示屏210和红外光探测器230之间。
可选地,终端设备200还可以包括通孔250。这样,可以减少不必要的信号衰减,使得穿过所述显示屏210的所述反射光可以顺利的被所述信号探测器接收。
作为一种可能的实现方式,遮光层240可以设置有通孔250,红外光探测器230位于该通孔250范围内。红外光探测器230可以通过通孔250接收反射光,例如,该反射光可以为红外光发射器220发出的红外光经外部物体反射后形成的反射光,该反射光可以为红外光发射器220发出的红外光经盖板玻璃212反射后形成的反射光。
可选地,显示屏210可以包括油墨层213,油墨层213可以位于盖板玻璃212内侧。进一步地,油墨层213可以印刷在盖板玻璃212内侧。
可选的,所述信号发射器和所述信号探测器的中心在一条直线上。如图1所示。当然,所述信号发射器和所述信号探测器的中心也可以不在一条直线,所述信号探测器在所述反射光的可能区域,保证可以接收到所述反射光即可,本申请实施例不做具体限定。
在本申请实施例中,接近传感器可以感应终端设备和接近物体之间的距离,从而使得终端设备可以根据接近传感器检测的终端设备和接近物体的距离,控制终端设备熄屏或亮屏。
一般来说,终端设备中的接近传感器的性能需要满足一定的要求,才能使终端设备在预定的距离熄灭或点亮显示屏。接近传感器的性能是指接近传感器感应接近物体距离的灵敏度。
例如,要想使得终端设备在预定的距离熄灭或点亮显示屏,需要接近传感器在终端设备和接近物体之间相距预定的距离时,能够感应到接近物体,也就是说,接近传感器的性能需要能够实现,在预定的距离感应到接近物体。
接近传感器的性能可以通过接近传感器的信噪比(signal noise ratio,SNR)来体现。因此,要想使得接近传感器在预定的距离感应到接近物体,接近传输器的SNR需要满足一定的要求。
例如,若终端设备需要在与接近物体的距离小于或等于2cm时进入接近状态,并在与接近物体的距离大于或等于5cm时进入远离状态,则接近传感器的SNR数值需要大于或等于5。
如图5所示,接近传感器的SNR由红外光探测器230接收到的由接近物体反射光线219的能量值、红外光探测器230接收到的非接近物体反射光线217的能量值和红外光探测器230的数据抖动决定。红外光探测器230的数据抖动是指红外光探测器的偏置误差,由红外光探测器230的器件本身的性能决定。红外光探测器230的数据抖动是一个固定值。
具体地,SNR=(pdata-crosstalk)/jitter。其中,pdata表示红外光探测器230接收到的接近物体反射光线219的能量值,crosstalk表示红外光探测器230接收到的非接近物体反射光线217的能量值,jitter表示红外光探测器的数据抖动。
pdata与红外光发射器的辐射强度和显示屏的红外光透过率等相关。红外光发射器的辐射强度越大、显示屏的红外光透过率越高,则pdata越大;反之,则pdata越小。
crosstalk与红外光发射器的辐射强度、显示屏的红外光透过率,以及红外光发射器与红外光探测器之间的距离等相关。红外光发射器的辐射强度越大、显示屏的红外光透过率越低、红外光发射器与红外光探测器的距离越近、则crosstalk越大;反之,则crosstalk越小。
下面结合图5介绍红外光发射器与红外光探测器之间的距离,以及红外光发射器的辐射强度应如何取值,才能使得接近传感器的SNR满足需求,从而使得接近传感器的性能满足需求,最终使得终端设备可以在预定的距离熄灭或点亮显示屏。
如图5所示,在本申请实施例中,终端设备的红外光探测器230位于显示区域218的盖板玻璃212和显示面板214下方,红外光发射器220位于非显示区域216的盖板玻璃212和/或油墨层213的下方。由此可知,显示屏的红外光透过率指盖板玻璃、显示面板和/或油墨层的红外光透过率。
同一介质的红外光透过率与红外光反射率相关,一般来说,红外光透过率越高,则其红外光反射率越低。比如,以盖板玻璃为例来说明,若盖板玻璃的红外光透过率越高,则该盖板玻璃的红外光反射率越低;若盖板玻璃的红外光透过率越低,则该盖板玻璃的红外光反射率越高。因此,pdata和crosstalk也可以认为是与显示屏(包括显示面板、盖板玻璃和/或油墨层)的红外光反射率相关。
基于上述描述,红外光发射器的辐射强度、显示屏的红外光透过率和红外光发射器与红外光探测器之间的距离对pdata和crosstalk的影响如下表所示。这里的红外光透过率指盖板玻璃、显示面板和/或油墨层的红外光透过率。
红外光发射器的辐射强度 红外光透过率 红外光发射器与红外光探测器之间的距离
pdata大 红外光发射器的辐射强度高 红外光透过率高 不影响
pdata小 红外光发射器的辐射强度低 红外光透过率低 不影响
crosstalk大 红外光发射器的辐射强度高 红外光透过率低 红外光发射器与红外光探测器之间的距离小
crosstalk小 红外光发射器的辐射强度低 红外光透过率高 红外光发射器与红外光探测器之间的距离大
显示面板的红外光透过率与显示面板的显示线路的走线密度和材质有关。通常来讲,同种材质的显示面板,显示面板的分辨率越高,显示线路的走线越密,红外光透过率越低;反之,红外光透过率越高。目前,显示面板的红外光透过率远低于盖板玻璃和油墨层。
本申请实施例的终端设备中,由于红外光探测器位于显示区域的盖板玻璃和显示面板内侧,即红外探测器接收的红外光需要经过显示面板,而显示面板的红外光透过率较小,会导致pdata变小且crosstalk变大,因此,要想使得本申请实施例中的接近传感器的SNR不小于现有技术中的接近传感器的SNR,则可以通过提高pdata和/或降低crosstalk来实现。此处所述的现有技术中的接近传感器中,红外光发射器和红外光探测器均位于显示屏的非显示区域。
要想提高pdata,可以提高红外光发射器的辐射强度。例如,可以红外光发射器的辐射强度提高3至4倍。例如,若红外光探测器位于显示屏的非显示区域时,红外光源的功率为2毫瓦每球面度(mW/sr),则可以将本申请实施例中的红外光发射器的辐射强度可以提升至6mW/sr以上。
要想降低crosstalk,可以增大红外光探测器与红外光发射器之间的距离。例如,可以将红外光探测器与红外光发射器之间的距离增大至2mm以上,进一步地,该距离还需要小于或等于6mm。
由上表可知,提高红外光发射器的辐射强度以增大pdata时,crosstalk也会相应增大。因此,提高红外光发射器的辐射强度以增大pdata时,可以同时增大红外光探测器与红外光发射器之间的距离来减小crosstalk,从而可以更好地保证接近传感器的SNR不小于现有技术中的接近传感器的SNR。
例如,红外光发射器的辐射强度可以设置第一预设辐射强度,红外光发射器与红外光探测器之间的距离可以设置为第二预设范围,且第一预设辐射强度和第二预设范围应该使得接近传感器的SNR不小于预设的SNR阈值,例如,不小于现有技术中的接近传感器的SNR。现有技术中的接近传感器的SNR的一种取值范围为不小于5。
第一预设辐射强度与第二预设范围可以通过有限元方法仿真得到。例如,可以通过仿真软件,不断调整红外光发射器的辐射强度和红外光发射器与红外光探测器之间的距离,直到根据红外光探测器接收到的接近物体反射光线的能量值pdata、红外光探测器接收到的非接近物体反射光线的能量值crosstalk和红外光探测器的数据抖动jitter计算得到的SNR大于或等于预设的SNR阈值。此时的红外光发射器的辐射强度即为第一预设辐射强度,红外光发射器与红外光探测器之间的距离为第二预设范围。
例如,想要保证本申请实施例中的接近传感器的SNR不小于5,可以在将红外光发射器的辐射强度相对于现有的终端设备中的红外光发射器的辐射强度提高3至4倍的同时,将红外光探测器与红外光发射器之间的距离增大至2mm以上。
可选地,红外光探测器与红外光发射器之间的距离可以小于或等于6mm。
例如,现有的终端设备中的红外光发射器的辐射强度为2mW/sr,红外光探测器与红外光发射器之间的距离位于1至2mm,且SNR不小于5时,基于这些数据进行有限元仿真,可以得到如下结果:第一预设辐射强度大于4mW/sr,或第一预设辐射强度大于或等于6mW/sr,和/或,第二预设范围大于2mm,且第二预设范围可以小于或等于6mm。这样可以使得本申请实施例的终端设备可以在预定的距离熄灭或点亮显示屏。该预定的距离可以与现有技术中的终端设备熄灭或点亮显示屏的距离相同。
由于终端设备的红外光探测器实际检测到的红外光中通常会包含接近物体反射光线的能量值(pdata)和非接近物体反射光线的能量值(crosstalk),因此,终端设备中会根据红外光探测器与红外光发射器之间的距离预设一个非接近物体反射光线的能量值(crosstalk0)。
例如,红外光探测器与红外光发射器之间的距离为5mm时,终端设备中预设与5mm对应的crosstalk 0。5mm对应的crosstalk 0是指:红外光探测器与红外光发射器之间的距离为5mm时,非接近物体反射光线的能量值。
这样,终端设备确定其是否处于接近状态或远离状态时,可以将红外光探测器实际探测到的红外光的能量值(pdata+crosstalk)减去预先设置的crosstalk 0,从而得到接近物体反射光线的能量值,并将该能量值与pdata1或pdata2相比较,然后根据比较结果确定终端设备处于接近状态还是处于远离状态。
其中,pdata1为预设的、终端设备刚好处于接近状态时接近物体反射光线的能量值,pdata2为预设的、终端设备刚好处于远离状态时接近物体反射的红外光的能量值。可选地,pdata1与pdata2可以相等。
但是在实际的装配过程中,由于安装设备精度或工艺水平等问题,终端设备中的红外光发射器和红外光探测器位置在安装时会产生偏差,从而使得红外光发射器和红外光探测器之间的实际安装距离与期望安装距离之间有偏差,即红外光探测器与红外光发射器之间的实际安装距离不等于红外光探测器与红外光发射器之间的期望安装距离。比如,红外光探测器与红外光发射器之间的期望安装距离为5mm,但红外光探测器与红外光发射器之间的实际安装距离可能只有4.9mm,与5mm相比有0.1mm的偏差。
由于红外光探测器与红外光发射器之间的不同的距离对应的非接近物体反射光线的能量值不同,因此,红外光发射器和红外光探测器之间的实际安装距离与期望安装距离之间有偏差时,红外光探测器实际检测到的红外光中的非接近物体光线的能量值与终端设备中预设的非接近物体光线的能量值有偏差。这种情况下,若终端设备中还按照红外光发射器和红外光探测器之间的期望安装距离来预设非接近物体光线的能量值,则会导致终端设备根据该能量值所计算得到的接近物体光线的能量值不准确。
针对该问题,本申请提出一种控制终端设备的方法。该方法包括:在终端设备的红外光发射器所发出的红外光未经外部物体反射时,终端设备的红外光探测器检测红外光,并将检测到的红外光的能量值预设为非接近物体光线的能量值,以及根据该预设的非接近物体光线的能量值控制终端设备熄灭屏幕或点亮屏幕。
终端设备通过这种方法预设的非接近物体光线的能量值,并根据该预设的非接近物体光线的能量值控制终端设备熄灭屏幕或点亮屏幕,可以提高终端设备熄灭屏幕或点亮屏幕的准确率。
本申请一个实施例的控制终端设备的方法可以包括如下三个步骤。
步骤一:获取第一值,所述第一值是在终端设备的红外光发射器所发出的红外光未经外部物体反射时,所述终端设备的红外光探测器所检测到的红外光的能量值。
该第一值可以是在终端设备的红外光发射器所发出的红外光未经外部物体反射时,终端设备的红外光探测器检测到的红外光的能量值,该能量值被预设在终端设备中作为非接近物体光线的能量值。可以在终端设备出厂之前配置终端设备时在终端设备上配置好该第一值。
应理解,第一值是在终端设备显示屏上方没有物体遮挡的情况下,红外光发射器所发出的红外光未经外部物体反射时,红外光探测器检测到红外光后输出的数值。由于显示屏上方没有接近物体,因此这里的第一值为非接近物体反射光线的能量。例如,第一值可以是盖板玻璃和显示面板反射的红外光的能量值。
需要注意的是,若存在安装偏差,该第一值相比红外光探测器与红外光发射器之间的预设安装距离对应的非接近物体反射的红外光的能量值相比,可能会有较大的偏差。
步骤二:获取第二值,所述第二值是在终端设备的红外光发射器所发出的红外光经外部物体反射时,所述终端设备的红外光探测器所检测到的红外光的能量值。
第二值可以是用户设备在使用终端设备的过程中获取的。
应理解,第二值是在终端设备显示屏上方有物体遮挡的情况下,红外光发射器所发出的红外光经外部物体反射后,红外光探测器检测到红外光后输出的数值。此时显示屏上方有接近物体,因此,该第二值为接近物体反射光线与非接近物体反射光线的能量之和。也就是说,第二值即包括终端设备的红外光发射器所发出的红外光经接近物体反射后,红外光探测器所检测到的红外光,也包括未经接近物体反射,而直接被盖板玻璃、油墨或显示面板等反射后,红外光探测器所检测到的红外光。
步骤三:根据所述第一值和第二值控制所述终端设备熄灭显示屏或点亮显示屏。
在一些可能的实现方式中,可以根据第二值减去第一值之后得到的第三值控制终端设备熄灭显示屏或点亮显示屏。
例如,当所述第三值大于或等于第一阈值时,控制所述终端设备熄灭显示屏;当所述第三值小于或等于第二阈值时,控制所述终端设备点亮显示屏。
例如,终端设备可以保存预先设置的进入接近状态的距离对应的红外光的能量值(第一阈值)。比如,终端设备的显示屏与接近物体之间的距离小于或等于2cm时,该终端设备进入接近状态,即熄灭显示屏,则终端设备可以保存该终端设备的显示屏与接近物体之间的距离为2cm时,仅有接近物体反射的红外光的能量值记为第一阈值。
当确定终端设备是否处于接近状态时,可以将红外光探测器实时检测到的红外光的能量值(即第二值)减去第一值,并将得到的第三值与预存的第一阈值比较,当第三值大于或等于该第一阈值时,控制该终端设备进入接近状态,即熄灭显示屏。
例如,终端设备可以保存预先设置的进入远离状态的距离对应的红外光的能量值(第二阈值)。比如,终端设备的显示屏与接近物体之间的距离大于或等于5cm时,该终端设备进入远离状态,即点亮显示屏,则终端设备可以保存该终端设备的显示屏与接近物体之间的距离为5cm时,仅有接近物体反射的红外光的能量值记为第二阈值。
当确定终端设备是否处于远离状态时,可以将红外光探测器实时检测到的红外光的能量值(即第二值)减去第一值,并将得到的第三值与预存的第二阈值比较,当第三值小于或等于该第二阈值时,控制该终端设备进入远离状态,即点亮显示屏。
可选地,可以通过上述控制终端设备的方法来测试终端设备是否合格。应理解,这里的测试流程可以是终端设备在出厂前进行的测试,比如,在终端设备出厂前,检测该终端设备能否在预定的距离进入接近状态和/或远离状态。本申请一个实施例的测试终端设备的方法包括如下四个步骤。
步骤一,启动接近光测试。
首先,启动接近光测试软件。可选地,该接近光测试软件可以为安装在终端设备中的应用(APP)。
终端设备的接近传感器安装好后,可以对终端设备进行接近光测试,即测试终端设备是否可以在预设的距离范围进入接近状态和远离状态。
例如,若终端设备与物体之间的距离位于预设的距离范围内,该终端设备处于接近状态,则说明终端设备的接近状态合格;反之不合格。若终端设备与物体之间的距离大于或等于预设的距离阈值,该终端设备处于远离状态,则说明终端设备的远离状态合格;反之不合格。
步骤二,测试终端设备接近传感器的接近状态。
例如,可以逐渐减小接近物体与终端设备显示屏之间的距离。在这个过程中终端设备多次执行前述控制终端设备的方法中的三个步骤。具体地址,获取第一值和获取第二值,并用第二值减去第一值得到第三值,以及将第三值与预存的第一阈值比较。第三值与第一阈值的一种比较结果为第三值小于第一阈值,另一种比较结果为第三值大于或等于第一阈值。
若用“0”表示第三值小于第一阈值,用“1”表示第三值大于或等于第一阈值,则接近光测试软件获取到的比较结果为由“0”变为“1”时,测量接近物体与终端设备的显示屏之间的距离,并判断该距离与预设的距离阈值之间的差值是否满足预设的条件。
例如,预设接近物体与终端设备的显示屏之间的距离小于或等于2cm时,终端设备处于接近状态,则可以预设第一阈值为2cm。此时,若测量的接近物体与终端设备的显示屏之间的距离与2cm相等,或测量的接近物体与终端设备的显示屏之间的距离与2cm之间的差值位于预设的范围内,则可以确定该终端设备的接近状态合格。
步骤三,测试终端设备接近传感器的远离状态。
例如,可以逐渐增大接近物体与终端设备显示屏之间的距离。在这个过程中终端设备多次执行前述控制终端设备的方法中的三个步骤。具体地址,获取第一值和获取第二值,并用第二值减去第一值得到第三值,以及将第三值与预存的第二阈值比较。第三值与第二阈值的一种比较结果为第三值大于第二阈值,另一种比较结果为第三值小于或等于第二阈值。
若用“1”表示第三值大于第二阈值,用“0”表示第三值小于或等于第二阈值,则接近光测试软件获取到的比较结果为由“1”变为“0”时,测量接近物体与终端设备的显示屏之间的距离,并判断该距离与预设的距离阈值之间的差值是否满足预设的条件。
例如,预设接近物体与终端设备的显示屏之间的距离大于或等于5cm时,终端设备处于远离状态,则可以预设第二阈值为5cm。此时,若测量的接近物体与终端设备的显示屏之间的距离与5cm相等,或测量的接近物体与终端设备的显示屏之间的距离与5cm之间的差值位于预设的范围内,则可以确定该终端设备的远离状态合格。
步骤四,结束接近光测试。
若该终端设备在预先设置的进入接近状态的距离进入接近状态,且在预先设置的进入远离状态的距离进入远离状态,则该终端设备的接近光测试合格;否则,该终端设备的接近光测试不合格。
