本发明实施例公开了一种显示屏的控制方法及装置，用于便捷地对光量数据阈值进行调整，实现对终端设备显示屏的显示状态的准确控制。以下分别进行详细说明。
本发明实施例中所描述的终端设备具体可以包括但不限于：配备显示屏的头戴式显示设备等。
请参阅图1，为本发明实施例提供的一种显示屏的控制方法的流程示意图。本实施例中所描述的显示屏的控制方法，包括：
101、终端设备获取在第一用户佩戴所述终端设备的过程中光传感器采集的目标光量数据。
在一些可行的实施方式中，终端设备在执行步骤101之前，可以先执行以下步骤：
终端设备获取在第二用户佩戴终端设备的过程中光传感器采集的多个光量数据，并按照预设写入次数将该多个光量数据重复写入到第一光量数据历史值文件中。
其中，第二用户具体可以是终端设备的开发人员，光传感器具体可以发射红外光，并接收反射回的红外光，以及计算红外光的反射量(记为光量数据)，在第二用户多次佩戴终端设备的过程中，终端设备利用光传感器采集第二用户佩戴终端设备时的光量数据以及第二用户摘下终端设备时的光量数据，并按照预设写入次数将佩戴终端设备时的光量数据以及摘下终端设备时的光量数据重复写入到第一光量数据历史值文件中，例如，第二用户佩戴5次终端设备，则通过光传感器可以采集到第二用户5次佩戴终端设备时对应的5个光量数据，以及第二用户5次摘下终端设备时对应的5个光量数据，并按照预设写入次数为20次将这10个光量数据(包括第二用户5次佩戴终端设备时对应的5个光量数据和5次摘下终端设备时对应的5个光量数据)重复写入到第一光量数据历史值文件中，则第一光量数据历史值文件中可以包含100个光量数据，以减小单个光量数据出错对整体光量数据的影响。当然，如果第二用户佩戴终端设备的次数比较多，则采集到的多个光量数据可以一次性写入到第一光量数据历史值文件中，而不必再重复多次写入，例如，可以让第二用户佩戴50次终端设备，通过光传感器采集到第二用户50次佩戴终端设备时对应的50个光量数据，以及第二用户50次摘下终端设备时对应的50个光量数据，并将这100个光量数据(包括第二用户50次佩戴终端设备时对应的50个光量数据和50次摘下终端设备时对应的50个光量数据)一次性写入到第一光量数据历史值文件中。
此外，终端设备还可以根据第二用户佩戴终端设备的过程中光传感器采集的多个光量数据确定出光量数据阈值的初始值，从而在终端设备的后续使用 中，终端设备可以根据光量数据阈值的初始值对显示屏的显示状态进行控制，具体包括：如果光传感器采集的光量数据达到光量数据阈值的初始值，则终端设备确定有用户佩戴上了该终端设备，并控制显示屏为第一显示状态；如果光传感器采集的光量数据小于光量数据阈值的初始值，则终端设备确定当前用户摘下了该终端设备，并控制显示屏为第二显示状态。
需要说明的是，本发明实施例中所描述的显示屏的显示状态具体可以是指开关状态。当然，显示屏的显示状态具体也可以是指休眠状态，屏保状态，屏幕亮度，等等。第一显示状态和第二显示状态具有对立关系，例如，显示状态为开关状态时，第一显示状态对应于用户佩戴终端设备，为显示屏开启；第二显示状态对应于用户摘下终端设备，为显示屏关闭。再例如，显示状态为休眠状态时，第一显示状态对应于用户佩戴终端设备，为显示屏不休眠；第二显示状态对应于用户摘下终端设备，为显示屏休眠。又例如，显示状态为屏保状态时，第一显示状态对应于用户佩戴终端设备，为显示屏不显示屏保画面；第二显示状态对应于用户摘下终端设备，为显示屏显示屏保画面。又例如，显示状态为屏幕亮度时，第一显示状态对应于用户佩戴终端设备，为显示屏的屏幕亮度大于或等于预设第一亮度；第二显示状态对应于用户摘下终端设备，为显示屏的屏幕亮度小于或等于预设第二亮度，且预设第一亮度大于预设第二亮度。
具体实现中，第一用户可以是普通消费者用户，目标光量数据可以为采集的光量数据的最大值和最小值，在第一用户佩戴终端设备的过程(即从第一用户佩戴上终端设备到第一用户摘下终端设备)中，终端设备通过光传感器不断采集光量数据，从不断采集的光量数据中确定出光量数据的最大值和光量数据的最小值，光量数据的最大值通常对应于第一用户佩戴上终端设备时，光量数据的最小值通常对应于第一用户摘下终端设备时。
102、所述终端设备利用所述目标光量数据对第一光量数据历史值文件进行更新，得到第二光量数据历史值文件。
具体实现中，终端设备可以将采集到的光量数据的最大值和最小值添加到第一光量数据历史值文件中，并从第一光量数据历史值文件中剔除两个存储在预设位置的光量数据，得到第二光量数据历史值文件，从而利用新采集的目标光量数据替换掉第一光量数据历史值文件中采集时间较早的光量数据，实现对 新采集的目标光量数据的记录，以及第一光量数据历史值文件的更新。例如，终端设备可以将新采集的光量数据的最大值和最小值添加到第一光量数据历史值文件的头部，并剔除第一光量数据历史值文件尾部的两个光量数据。当然，终端设备也可以将新采集的光量数据的最大值和最小值添加到第一光量数据历史值文件的尾部，并剔除第一光量数据历史值文件头部的两个光量数据，本发明实施例不做限定。
103、所述终端设备利用所述第二光量数据历史值文件确定光量数据阈值。
具体实现中，终端设备对第二光量数据历史值文件包括的光量数据进行排序，得到第三光量数据历史值文件，可以将第三光量数据历史值文件中除排在首位和末位之外的光量数据均作为预设的多个分类点，利用该预设的多个分类点分别将第三光量数据历史值文件包括的光量数据分为两类，即第三光量数据历史值文件中的第一个光量数据到分类点对应的光量数据划为一类，分类点对应的光量数据的下一个光量数据到最后一个光量数据划为一类。终端设备获取以各个分类点对第三光量数据历史值文件进行划分时得到的这两类光量数据的类间方差，从该多个分类点中确定出目标分类点，目标分类点对应的类间方差最大，类间方差用于评判分类结果的好坏，类间方差越大代表这两类光量数据的整体差距越大，对应的分类效果越好，并且利用目标分类点将第三光量数据历史值文件分成的两类光量数据分别对应为戴上终端设备时的光量数据和摘下终端设备时的光量数据，进而可以利用分类效果最好(即类间方差最大)时的目标分类点重新确定光量数据阈值。
进一步地，终端设备利用目标分类点重新确定光量数据阈值的具体方式可以是：终端设备获取目标分类点对应的光量数据和目标分类点对应的光量数据的下一个光量数据，将光量数据阈值设为大于目标分类点对应的光量数据，且小于目标分类点对应的光量数据的下一个光量数据即可，或者，也可以将光量数据阈值设为目标分类点对应的光量数据和目标分类点对应的光量数据的下一个光量数据的平均值。
在一些可行的实施方式中，终端设备利用目标分类点重新确定光量数据阈值的具体方式还可以是：终端设备以目标分类点将排序后的光量数据历史值文件包括的光量数据分为两类(设为第一类和第二类)，计算第一类光量数据的 平均值和第二类光量数据的平均值，再根据这两类光量数据各自的平均值确定出光量数据阈值，例如，可以将光量数据阈值设为第一类光量数据的平均值和第二类光量数据的平均值的平均值，从而可以避免采集的部分光量数据(如目标分类点对应的光量数据和/或目标分类点对应的光量数据的下一个光量数据)出错而导致得到的光量数据阈值不合理，进而出现终端设备对显示屏显示状态的控制不准确的情况。
举例来说，以第一光量数据历史值文件包括10个光量数据为例，且第一光量数据历史值文件包括的数据为：(50,150,50,150,50,150,50,150,50,150)，设终端设备获取的目标光量数据包括的最大值和最小值分别为160和60，终端设备可以将60和160添加到第一光量数据历史值文件的头部，并剔除第一光量数据历史值文件尾部的两个光量数据50和150，则得到的第二光量数据历史值文件包括的数据为：(60,160,50,150,50,150,50,150,50,150)，对第二光量数据历史值文件包括的光量数据进行从小到大的排序，得到第三光量数据历史值文件，将第三光量数据历史值文件包括的光量数据记为数组array[10]，则array[10]＝{50,50,50,50,60,150,150,150,150,160}，将array[10]中的前面9个元素分别作为分类点将第三光量数据历史值文件包括的光量数据分为两类，获取这两类光量数据的类间方差，例如，以第5个元素array[4]＝60作为分类点时，则可以将数组array[10]中的10个元素划分为前面5个元素(即50,50,50,50,60)为第一类光量数据，后面5个元素(即150,150,150,150,160)为第二类光量数据，根据公式类间方差g＝w1*w2*(u1-u2)2计算第一类光量数据和第二类光量数据之间的类间方差，w1为第一类光量数据占全部光量数据的数量百分比，w2为第二类光量数据占全部光量数据的数量百分比，u1为第一类光量数据的平均值，u2为第二类光量数据的平均值，通过计算可知，当以第5个元素array[4]＝60作为分类点时，对应的类间方差g最大，也即目标分类点为第5个元素60，此时，光量数据阈值可以在第5个元素60和第6个元素150之间任取一个值，例如，光量数据阈值取90，或者，光量数据阈值也可以取第5个元素60和第6个元素150的平均值(60+150)/2＝105。
在一些可行的实施方式中，为了避免采集的部分光量数据(如目标分类点对应的光量数据和/或目标分类点对应的光量数据的下一个光量数据)出错而 导致得到的光量数据阈值不合理，终端设备可以将光量数据阈值设为第一类光量数据的平均值和第二类光量数据的平均值的平均值，即光量数据阈值为(u1+u2)/2＝(52+152)/2＝102。另外，如果在设终端设备的后续使用过程中，终端设备获取的目标光量数据包括的最大值和最小值与正常情况下偏差较大，例如，目标光量数据包括的最大值和最小值分别为50和50，利用50和50对第二光量数据历史值文件更新得到的光量数据历史值文件包括的光量数据为：(50,50,60,160,50,150,50,150,50,150)，利用上述计算公式重新计算得到的光量数据阈值为(u1+u2)/2＝(51.7+152.5)/2＝102.1，可见当终端设备获取的目标光量数据出错时，重新计算得到的光量数据阈值102.1与之前计算得到的光量数据阈值102相比变动很小，从而本发明实施例提供的光量数据阈值确定方案鲁棒性高，系统稳定性强。
104、所述终端设备根据所述光量数据阈值对所述终端设备的显示屏的显示状态进行控制。
具体实现中，终端设备获取光传感器实时采集的当前光量数据，将当前光量数据与确定出的光量数据阈值进行比较，如果当前光量数据小于光量数据阈值，则终端设备确定用户摘下了终端设备，并控制显示屏为第一显示状态；如果当前光量数据大于或等于光量数据阈值，则终端设备确定有用户佩戴上了终端设备，并控制显示屏为第二显示状态，从而实现对终端设备显示屏的显示状态的准确控制。
本发明实施例中，终端设备获取在第一用户佩戴终端设备的过程中光传感器采集的目标光量数据，利用该目标光量数据对第一光量数据历史值文件进行更新，得到第二光量数据历史值文件，利用该第二光量数据历史值文件确定光量数据阈值，进而根据该光量数据阈值对该终端设备的显示屏的显示状态进行控制，从而可以便捷地对光量数据阈值进行调整，以自动适配不同的用户，并实现对终端设备显示屏的显示状态的准确控制。
