Abstract

一种控制显示屏背光的方法、装置、电子设备以及存储介质。该方法结合通话状态下电子设备(70)与预设方向的夹角以及是否有物体遮挡光孔，确定显示屏背光亮或灭的调节，即使在光孔被深色头发覆盖等的场景，仍可准确调节显示屏背光的亮或灭。

Description

控制显示屏背光的方法、装置、电子设备以及存储介质 技术领域
本发明实施例涉及通信技术，尤其涉及一种控制显示屏背光的方法、装置、电子设备以及存储介质。
背景技术
在终端中，接近光传感器包括红外线发射二极管(Infrared Emitting Diode，简称：IR LED)和红外线接收器。另外，在终端的显示屏上，接近听筒位置设置有光孔。如图1所示，IR LED 11通过光孔12向外发射红外光，红外线接收器13接收光孔12外被位于IR LED发射红外光的方向上的物体反射回来的红外光，并将所接收到的红外光的强度值传递给处理器(未示出)；处理器根据红外光的强度值判断是否有物体接近光孔；当判断没有物体接近光孔时，开启显示屏背光；当判断有物体接近光孔时，关闭显示屏背光，进而达到自动调节显示屏背光的亮或灭以节省功耗。其中，物体离光孔越近，红外线接收器接收到物体反射的红外光的强度值就越大。
其中，处理器根据红外光的强度值判断是否有物体接近光孔，具体为：当该红外光的强度值大于或等于上限值时，处理器确定有物体接近光孔，该上限值为预先设置的关闭显示屏背光的门限值；当该红外光的强度值小于或等于下限值时，处理器确定没有物体接近光孔，下限值为预先设置的开启显示屏背光的门限值。
但考虑到光孔被深色物体(如：头发)覆盖等场景，由于深色物体吸收光线能力较强，因此，当光孔被深色物体覆盖时，IR LED发出的光线被深色物体吸收，反射至红外线接收器的红外光强度较弱。例如：通话过程中，用户将终端靠近耳边，正常情况下，IR LED所发射的红外光经光孔外被人耳反射回至红外线接收器，红外线接收器向处理器传递的红外光的强度值大于上限值，处理器进而判断有物体遮挡光孔，关闭显示屏背光。但当用户通话时，将终端放在耳边，恰巧有头发遮挡光孔时，使IR LED所发射的光线被头发吸收，反射至红外线接收器的红外光的强度值小于下限值，处理器进而判断当 前没有物体遮挡光孔，控制显示屏为开启状态，导致显示屏背光调节的不准确。
发明内容
本发明实施例提供一种控制显示屏背光的方法、装置、电子设备以及存储介质，以在光孔被深色物体覆盖的情况下，提高显示屏背光亮灭调节的准确度。
第一方面，本发明实施例提供一种控制显示屏背光的方法，应用于具有接近光传感器的电子设备，所述电子设备上设置有光孔，接近光传感器通过光孔检测红外光强度，方法包括：当检测到电子设备处于通话状态时，确定电子设备与预设方向的夹角，并确定是否有物体遮挡光孔；当电子设备与预设方向的夹角大于或等于预设角度，且有物体遮挡光孔时，关闭显示屏背光。
该发明实施例在检测到电子设备处于通话状态时，确定电子设备与预设方向的夹角，并确定是否有物体遮挡光孔；当电子设备与预设方向的夹角大于或等于预设角度，且有物体遮挡光孔时，关闭显示屏背光。这样，结合通话状态下电子设备与预设方向的夹角以及是否有物体遮挡光孔，确定关闭或开启显示屏背光，相对现有技术仅根据是否有物体遮挡光孔来关闭或开启显示屏背光的方案，本发明实施例可提高显示屏背光亮或灭调节的准确度，提升用户体验。
在第一方面的第一种可能的实现方式中，预设方向为竖直方向。确定电子设备与预设方向的夹角，可以包括：确定垂直于电子设备的显示屏所在平面的轴与竖直方向的夹角；或者，确定电子设备的显示屏所在平面与竖直方向的夹角。
在第一方面的第二种可能的实现方式中，确定是否有物体遮挡光孔，包括：确定当前的红外光强度值；如果当前的红外光强度值大于或等于预设阈值，确定有物体遮挡光孔；或者，如果当前的红外光强度值小于预设阈值，确定没有物体遮挡光孔。
在第一方面的第三种可能的实现方式中，预设阈值为当深色物体遮挡光孔时，所述接近光传感器所接收到的红外光强度值。
在本发明实施例中，由于预设阈值是当深色物体遮挡光孔时，红外线接 收器所接收到的红外光强度值，由于深色物体吸收红外光强度能力较强，因此当深色物体遮挡光孔时，红外线接收器接收到的红外光的强度较弱，因此，预设阈值小于下限值。当通话状态，用户手持电子设备，黑头发遮挡光孔时，由于红外线发射器发射的红外光大部分被黑头发吸收，反射至红外线接收器的红外光可能小于下限值，大于等于预设阈值，根据该红外光强度判断此时有物体遮挡光孔，进而关闭显示屏背光，相对现有技术可提升用户体验，减小损耗，延长电池使用时间。
在第一方面的第四种可能的实现方式中，该方法还包括：当电子设备与预设方向的夹角大于或等于预设角度，且没有物体遮挡光孔时，开启显示屏背光。该具体实现方式与上述实施例的区别仅在于是否有物体遮挡光孔。可避免非耳边通话场景关闭显示屏背光影响用户体验。
在一种可能的设计中，为避免误操作，当电子设备保持与预设方向的夹角大于或等于预设角度的持续时长大于第一预设时长，和/或，有物体遮挡光孔的持续时长大于第二预设时长时，关闭显示屏背光。其中，第一预设时长与第二预设时长可相等或不等，本发明实施例不予限制。该实现方式可避免显示屏背光亮或灭的乒乓调节。
第二方面，本发明实施例提供一种控制显示屏背光的装置，应用于具有接近光传感器的电子设备，所述电子设备上设置有光孔，接近光传感器通过光孔检测红外光强度，装置包括：确定模块，用于当检测到电子设备处于通话状态时，确定电子设备与预设方向的夹角，并确定是否有物体遮挡光孔；处理模块，用于当电子设备与预设方向的夹角大于或等于预设角度，且有物体遮挡光孔时，关闭显示屏背光。
基于同一发明构思，由于该装置解决问题的原理与第一方面的方法设计中的方案对应，因此该装置的实施可以参见方法的实施，重复之处不再赘述。
第三方面，本发明实施例提供一种控制显示屏背光的电子设备。该电子设备具有接近光传感器。接近光传感器包括红外线发射二极管和红外线接收器。该电子设备上设置有光孔。所述红外线发射二极管发射红外光。红外线接收器通过光孔检测红外光强度。电子设备还包括：处理器和存储器。其中，存储器用于存储可执行指令。处理器调用存储在所述存储器中的指令以实现上述第一方面的方法设计中的方案，重复之处不再赘述。

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。
本发明的说明书、权利要求书及上述附图中的术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备 固有的其它步骤或单元。
图2为本发明控制显示屏背光的方法实施例一的流程示意图。本发明实施例提供一种控制显示屏背光的方法，该方法可由控制显示屏背光的装置执行，该装置可以通过软件和/或硬件的方式实现，该装置可以集成于例如手机和其他支持通话功能的电子设备中。需明确的是，电子设备具有显示屏和接近光传感器，显示屏上设置有光孔。如图2所示，该方法包括：
S101、当电子设备处于通话状态时，确定电子设备与预设方向的夹角，并确定是否有物体遮挡光孔；
S102、当电子设备与预设方向的夹角大于或等于预设角度，且有物体遮挡光孔时，关闭显示屏背光。
若电子设备检测到其处于通话状态，则确定电子设备与预设方向的夹角，以根据电子设备与预设方向的夹角结合通话状态判断用户持有电子设备的姿态，例如，用户是否持有电子设备在耳边接听电话。
对于电子设备与预设方向的夹角，本领域技术人员可以理解，首先设定一预设方向，当用户持有电子设备在耳边时，电子设备与该预设方向呈现一定角度。因此，在具体实现中可根据用户使用电子设备的习惯，统计得出用户持有电子设备在耳边时，电子设备与该预设方向的夹角的大小。
其中，电子设备与预设方向的夹角，如图3所示，可以是垂直于电子设备的显示屏所在平面的轴与竖直方向的夹角，即Az，其中，z轴表示垂直于显示屏所在平面的轴；或者，也可以是电子设备的显示屏所在平面与竖直方向的夹角，如Ax或Ay，其中，x轴平行于电子设备的上/下边缘，y轴平行于电子设备的左/右侧边缘。
在上述实施例中，预设方向可以为竖直方向。该场景下，上述确定电子设备与预设方向的夹角，可以包括：通过重力传感器，确定电子设备与竖直方向的夹角。例如，对于图3所示夹角，通过重力传感器可读出x、y、z轴三个方向的加速度Gx、Gy和Gz，根据以下关系式可获得Ax、Ay和Az。
Gx＝g×cosAx
Gy＝g×cosAy
Gz＝g×cosAz
其中，g为重力加速度。
通过上述方式确定垂直于电子设备的显示屏所在平面的轴与竖直方向的夹角(即Az)或电子设备的显示屏所在平面与竖直方向的夹角(即Ax或Ay)。
另外，对于确定是否有物体遮挡光孔，仍参考图1，由于物体离光孔12越接近，被物体反射至红外线接收器13的红外光的强度值就越大，因此，可根据红外线接收器13接收到的红外光的强度值判断是否有物体遮挡光孔，当红外线接收器13接收到的红外光的强度值大于上限值时，可以判断有物体遮挡光孔。
当电子设备与预设方向的夹角大于或等于预设角度，且有物体遮挡光孔时，关闭显示屏背光(步骤S102)。
具体地，判断电子设备与预设方向的夹角与预设角度的大小关系，包括：电子设备与预设方向的夹角大于或等于预设角度，或者电子设备与预设方向的夹角小于预设角度。
当电子设备与预设方向的夹角大于或等于预设角度时，可以初步判断电子设备处于被用户手持状态，结合通话状态，确定用户持有电子设备在耳边，这里，将其定义为接听姿态；当电子设备与预设方向的夹角小于预设角度或非通话状态时，确定用户没有持有电子设备在耳边，将其定义为非接听姿态。
本领域技术人员可以理解地，本发明的实施例中给出的电子设备与预设方向的夹角与预设角度的大小关系，只是本发明实施例的一种实现具体可以根据设计需要进行适当的调整。
另需说明的是，接听姿态及非接听姿态仅用于区分用户是否持有电子设备在耳边的两种情况，也可以将用户是否持有电子设备在耳边的两种情况定义为其他术语，本发明实施例不对其进行限制。
图4示出物体与光孔之间的距离和红外线接收器所接收的红外光强度值的对应关系。如图4所示，横轴表示物体与光孔之间的距离，纵轴表示红外线接收器所接收的红外光强度值，物体与光孔之间的距离和红外线接收器所接收的红外光强度值呈反比例线性关系：物体与光孔之间的距离越大，红外线接收器所接收的红外光强度值越小。本领域可以理解，当红外光强度值大于或等于一阈值(例如下文中提及的预设阈值)时，物体距光孔的距离小于固定数值，即有物体遮挡或接近光孔。
优选的，为避免误操作，当电子设备保持与预设方向的夹角大于或等于预 设角度的持续时长大于第一预设时长，和/或，有物体遮挡光孔的持续时长大于第二预设时长时，关闭显示屏背光。其中，第一预设时长与第二预设时长可相等或不等，本发明不予限制。
该实施例在检测到电子设备处于通话状态时，确定电子设备与预设方向的夹角，并确定是否有物体遮挡光孔；当电子设备与预设方向的夹角大于或等于预设角度，且有物体遮挡光孔时，关闭显示屏背光。这样，结合通话状态下电子设备与预设方向的夹角以及是否有物体遮挡光孔，确定关闭或开启显示屏背光，相对现有技术仅根据是否有物体遮挡光孔来关闭或开启显示屏背光的方案，本发明实施例可提高显示屏背光亮或灭调节的准确度，提升用户体验。
可选地，上述确定是否有物体遮挡光孔，可以具体为：确定当前的红外光强度值；如果当前的红外光强度值大于或等于预设阈值，确定有物体遮挡光孔；或者，如果当前的红外光强度值小于预设阈值，确定没有物体遮挡光孔。其中，该预设阈值为当深色物体遮挡光孔时，红外线接收器所接收到的的红外光强度值。
其中，图5示出上限值、下限值、预设阈值及底噪值的示意图。参考图5，横轴表示物体与光孔的距离，纵轴表示红外光强度值，其中各具体数值，即横轴的1至10以及纵轴的10至80，仅为示例说明，不对本发明构成限制。在本发明实施例中，在上限值和下限值的基础上，增加预设阈值，且该预设阈值介于底噪值和下限值之间。
根据现有技术中定义，下限值为开启显示屏背光的门限值，即：当红外线接收器接收到的红外光强度值小于下限值时，开启显示屏背光；底噪值用于表征无物体遮挡光孔时的理想状态下的红外光的强度值。而在本发明实施例中，由于预设阈值是当深色物体遮挡光孔时，红外线接收器所接收到的红外光强度值，由于深色物体吸收红外光强度能力较强，因此当深色物体遮挡光孔时，红外线接收器接收到的红外光的强度较弱，因此，预设阈值小于下限值。当通话状态，用户手持电子设备，黑头发遮挡光孔时，由于红外线发射器发射的红外光大部分被黑头发吸收，反射至红外线接收器的红外光可能小于下限值，大于等于预设阈值，根据该红外光强度判断此时有物体遮挡光孔，进而关闭显示屏背光，相对现有技术可提升用户体验，减小损耗，延长 电池使用时间。
接下来，在上述实施例的基础上，通过具体实现方式说明其他调节显示屏背光的方法。
一种具体实现方式中，当电子设备处于通话状态时，确定电子设备与预设方向的夹角，并确定是否有物体遮挡光孔；当电子设备与预设方向的夹角大于或等于预设角度，且没有物体遮挡光孔时，开启显示屏背光。在该具体实现方式中，即使处于通话状态的电子设备位于人耳处，但由于红外线接收器接收的红外光强度小于预设阈值，也就是，人耳与光孔的距离较远，该情况下，开启显示屏背光。
该具体实现方式与上述实施例的区别仅在于是否有物体遮挡光孔。可避免非耳边通话场景关闭显示屏背光影响用户体验。
另一种具体实现方式中，该控制显示屏背光的方法还可以包括：当电子设备处于通话状态时，确定电子设备与预设方向的夹角，并确定是否有物体遮挡光孔；当电子设备与预设方向的夹角小于预设角度，且当前红外光的强度值小于下限值时，开启显示屏背光。该实现方式通过电子设备与预设方向的夹角小于预设角度和当前红外光的强度值小于下限值，即：判断此时电子设备处于非接听姿态，且没有物体遮挡光孔，开启显示屏背光，提升了用户体验。
又一种具体实现方式中，该控制显示屏背光的方法还可以包括：当电子设备处于通话状态时，确定电子设备与预设方向的夹角，并确定是否有物体遮挡光孔；当电子设备与预设方向的夹角小于预设角度，且当前红外光的强度值大于上限值时，关闭显示屏背光。该上限值用于有物体遮挡光孔时关闭显示屏背光的门限值。该实现方式通过当前红外光的强度值大于上限值，确定有物体遮挡光孔，即便电子设备处于非接听姿态，关闭显示屏背光。
结合图5、图2所示实施例以及该实现方式可知，无论电子设备与预设方向的夹角是大于或等于预设角度还是电子设备与预设方向的夹角小于预设角度，只要当前红外光的强度值大于上限值，即：只要确定有物体遮挡光孔，电子设备即关闭显示屏背光。
再一种具体实现方式中，该控制显示屏背光的方法还可以包括：当电子设备处于通话状态时，确定电子设备与预设方向的夹角，并确定是否有物体 遮挡光孔；当电子设备与预设方向的夹角小于预设角度，当前红外光的强度值小于或等于上限值，且当前红外光的强度值大于或等于下限值时，保持显示屏背光状态不变。也就是说，若前一时刻电子设备处于显示屏背光关闭状态，则当前时刻有上述条件成立时，电子设备仍保持显示屏背光处于关闭状态；若前一时刻电子设备处于显示屏背光开启状态，则当前时刻有上述条件成立时，电子设备仍保持显示屏背光处于开启状态。

可选地，确定模块61还可以用于：确定当前的红外光强度值；如果当前的红外光强度值大于或等于预设阈值，确定有物体遮挡光孔；或者，如果当前的红外光强度值小于预设阈值，确定没有物体遮挡光孔。
需说明的是，预设阈值为当深色物体遮挡光孔时，红外线接收器所接收到的红外光强度值。
可选地，处理模块62还可以用于：当电子设备与预设方向的夹角大于或等于预设角度，且没有物体遮挡光孔时，开启显示屏背光。
