具体实施方式
下面将结合附图及具体实施例进行详细描述。
实施例一
如图1所示，本发明实施例提供一种压力屏测试方法的流程示意图，包括以下步骤：
步骤S101、检测压力屏的压力传感器是否工作正常；
在本实施例中，移动终端在屏幕下方可以分布有S个独立的所述压力传感器，所述S为大于或等于1的整数，移动终端在屏幕上显示S个亮点(通常显示为绿点)，屏幕亮点所示屏幕下方为压力传感器安装位置，用手指稍用力按压亮点位置，该处压力传感器会产生形变响应，通过按压屏幕指定位置，获取该位置压力传感器的形变响应，来判定该处压力传感器异常、或安装异常。因此，可以通过按压S个亮点，并观察被按压的S个亮点是否有响应来检测所述压力屏对应的S个压力传感器是否工作正常，当亮点被按压有响应且消失时，该处压力传感器正常工作；当亮点被按压无响应且显示为红色，指示该位置有问题，该处压力传感器工作不正常。
例如：如图2所示，压力屏的屏幕下方分布有4个压力传感器，即S＝4，对应于4个所述压力传感器的安装位置显示有4个亮点，即图中阴影点(实际显示为绿点)，分别按压4个所述亮点，如果一所述亮点消失，则说明对应的压力传感器能够感受到压力，工作正常；如果一所述亮点显示为红色，则说明与该亮点对应的压力传感器不能感应到压力，工作不正常。也就是说，当每个压力传感器都工作正常时，则认为压力屏工作正常；当任一压力传感器工作不正常时，则认为压力屏工作不正常。当然，也可以通过检测按压时每个所述压力传感器感应的压力值或其他方式来检测所述压力屏的压力传感 器是否工作正常，其均在本申请的保护范围，在此不再进行赘述。
步骤S102、若所述压力屏的压力传感器工作正常，检测所述压力屏的压力感应均匀度，并判断所述压力感应均匀度是否达到预设的均匀度标准；
在本实施方式中，所述压力屏的压力感应均匀度反映所述压力屏不同位置受相同作用力时检测到的压力值的一致性。例如：分别以相同的压力按压位于所述压力屏的屏幕中间位置的8个测试点和位于所述压力屏的屏幕边缘位置的8个测试点，获取16个所述测试点受力时的压力值，可以将16个所述测试点受力时的压力值的偏差或几何平均值作为所述压力屏的压力感应均匀度。
其中，所述均匀度标准预设于所述移动终端的内存中，根据所述压力感应均匀度是否达到所述均匀度标准来判断所述是否需要对所述压力屏的压力传感器进行校准或维修处理。例如：所述均匀度标准为一范围值，假设为为[A，B]，其中A<B，若检测到所述压力屏不同位置的压力感应均匀度为大于或等于A，且小于或等于B，则所述压力屏的压力感应均匀度达到所述均匀度标准；若检测到所述压力屏不同位置的压力感应均匀度为小于A或大于B，则所述压力屏的压力感应均匀度未达到所述均匀度标准。步骤S103中，若所述压力感应均匀度达到所述均匀度标准，则确定所述压力屏为良品。
其中，当检测到所述压力屏的传感器均能正常工作且其屏幕区域每个位置的压力感应均匀度达到预设的所述均匀度标准，则所述压力屏为良品即合格品，无需进行校准或维修处理。
步骤S104、若所述压力屏的压力传感器不工作正常，或者所述压力感应均匀度未达到所述均匀度标准，则确定所述压力屏为不良品。
在本实施例中，上述步骤S101中，按压所述压力屏的当前界面中对应所述压力传感器所在位置的所述亮点并未全部消失，则确定所述压力传感器工作不正常，则确定所述压力屏为不良品，则需对所述压力屏进行校准，当无法校准时进行返修处理；或者上述步骤S102中，所述压力屏的屏幕中每个位置的压力感应均匀度未达到预设的所述均匀度标准，则压力传感器存在偏差，确定所述压力屏为不良品，需要对所述压力屏进行校准，当无法校准时进行返修处理。
本实施例中，上述方法可以应用于移动终端，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等。
本实施例中，检测压力屏的压力传感器是否工作正常；若所述压力屏的压力传感器工作正常，则检测所述压力屏的压力感应均匀度，并判断所述压力感应均匀度是否达到预设的均匀度标准；若所述压力感应均匀度达到所述均匀度标准，则确定所述压力屏为良品；若所述压力屏的压力传感器不工作正常，或者所述压力感应均匀度未达到所述均匀度标准，则确定所述压力屏为不良品。这样可以对压力屏进行检测，从而可以判断压力屏是否为良品。
如图3所示，本发明实施例提供的另一种压力屏测试方法的流程示意图，包括以下步骤：
步骤S301、检测压力屏的压力传感器是否工作正常；
步骤S302、若所述压力屏的压力传感器工作正常，则检测所述压力屏中预先指定的多个坐标点的坐标点压力感应均匀度，并判断所述多个坐标点的坐标点压力感应均匀度是否均达到预设的坐标点均匀度标准；
其中，步骤S301检测到所述压力屏的传感器均能正常工作时，步骤S302可以利用打点机以指定压力击打所述压力屏中预先指定的多个坐标点，击打每一坐标点时，每个所述压力传感器均能检测到初始压力值，利用内置于移动终端内的线性拟合算法可以将每个所述压力传感器的初始压力值进行线性拟合，从而获得每个坐标点的一个压力量化值即坐标点的压力值。例如：所述压力屏安装有4个所述压力传感器，当对所述压力屏上的预先指定的一坐标点击打时，4个所述压力传感器分别能检测到4个初始压力值，对所述4个初始压力值进行线性拟合即可获取该坐标点的压力值。所述压力屏的坐标点压力均匀度可以由所述预先指定的多个坐标点的压力值进行衡量，上述判断所述多个坐标点的坐标点压力感应均匀度是否均达到预设的坐标点均匀度标准可以判断坐标点的压力值是否达到预设的坐标点压力值标准。
可选的，该实施方式中，上述检测所述压力屏中预先指定的多个坐标点 的坐标点压力感应均匀度，并判断所述多个坐标点的坐标点压力感应均匀度是否均达到预设的坐标点均匀度标准步骤，可以包括：
步骤一、检测所述压力屏中预先指定的N×M个坐标点被相同压力按压时的检测压力值，所述M和所述N均为大于或等于1的整数；
其中，所述预先指定的N×M个坐标点可以阵列分布于整个所述压力屏中。例如：如图4所示，所述压力屏中预先指定60个坐标点，以10×6方式排列。同时，采用装配有200克(g)砝码的打点机对预先指定的60个坐标点进行打点，每一坐标点均能检测到一个检测压力值即该坐标点的压力值，该检测压力值由4个所述压力传感器的初始压力值进行线性拟合获得。
步骤二、判断所述N×M个坐标点中检测压力值最大的坐标点的检测压力值是否小于或者等于预设的检测压力阈值；
其中，选取所述N×M个坐标点中检测压力值最大的坐标点的检测压力值与预设的检测压力阈值进行比较，若所述检测压力值最大的坐标点的检测压力值大于大检测压力阈值，则所述N×M个坐标点的检测压力值存在异常；若所述检测压力值最大的坐标点的检测压力值小于或者等于检测压力阈值，则所述N×M个坐标点的检测压力值正常。所述检测压力阈值可以根据打点机装配的砝码大小进行选取，例如当采用200g砝码的打点机时，可以预设的检测压力阈值为1800。
步骤三、判断所述N×M个坐标点中的预先指定坐标点的检测压力值是否达到预设的均匀度标准；
其中，由于所述压力屏中安装的压力传感器数量有限且分布不均匀，位于所述压力屏中不同位置的坐标点对于相同的压力具有不同敏感度，当受相同压力按压时，反馈的检测压力值存在差异，例如，位于所述压力屏边缘的坐标点的敏感度点低于位于所述压力屏中间位置的坐标点的敏感度，位于边缘的坐标点反馈的检测压力值小于位于中间位置的坐标点反馈的检测压力值。故对于不同位置的坐标点需要预设不同的均匀度标准。
例如：如图4所示，图4中实心黑色点为位于所述压力传感器所在位置的坐标点。对于分别位于所述压力屏中4个角落位置的坐标点，例如，坐标点1，选取对应的均匀度标准为大于或等于30；对于位于所述压力屏左侧中 间位置的2个坐标点和位于所述压力屏右侧中间位置的2个坐标点，如坐标点2，选取对应的均匀度标准为大于或等于25；对于上述8个坐标点以外的其他坐标点，选取对应的均匀度标准为大于或等于50；而对于距离所述压力传感器最近的多个坐标点，也可以预先设置均匀度标准，如选取距离一个所述压力传感器最近的5个坐标点中最大的检测压力值，若所述压力屏具有4个所述压力传感器，则4个所述压力传感器对应4个最大的检测压力值，预设4个所述最大的检测压力值中的最大值与最小值的比值小于或等于2，即与该比值对应的均匀度指标为2。
步骤四、若所述压力值最大的坐标点的检测压力值小于或者等于所述检测压力阈值，且所述预先指定坐标点的检测压力值达到所述均匀度标准，则确定所述N×M个坐标点的坐标点压力感应均匀度均达到预设的坐标点均匀度标准。
其中，所述N×M个坐标点的坐标点压力感应均匀度均达到预设的坐标点均匀度标准，必须同时满足所述压力值最大的坐标点的检测压力值小于或者等于所述检测压力阈值，且所述预先指定坐标点的检测压力值达到所述均匀度标准。
例如：如图4所示，假设当采用装配200g砝码的打点机进行打点时，所述压力屏为良品必须同时满足：10×6个坐标点中所述检测压力值最大的坐标点的检测压力值小于或等于1800；位于所述压力屏中4个角落位置的坐标点的检测压力值均大于或者等于30，如坐标点1；位于所述压力屏左侧中间位置的2个坐标点和位于所述压力屏右侧中间位置的2个坐标点的检测压力值均大于或者等于25，如坐标点2；上述8个坐标点以外的坐标点的检测压力值均大于或等于50，如坐标点1和2以外的坐标点；以及4个所述压力传感器对应的4个所述最大的检测压力值中的最大值与最小值的比值小于或等于2。
步骤S303、若所述坐标点压力感应均匀度达到所述坐标点均匀度标准，则检测所述压力屏预先指定的多个坐标区域的坐标区域压力感应均匀度，并判断所述多个坐标区域的坐标区域压力感应均匀度是否均达到预设的坐标区域均匀度标准；
其中，由于所述压力屏预先指定的多个坐标区域中的每个坐标点对压力的敏感度比较接近，因此可以通过检测所述述压力屏预先指定的多个坐标区域的坐标区域压力感应均匀度来确定所述压力屏是否为良品，压力屏预先指定的多个坐标区域为N×M个坐标点中相邻2×2个坐标点围成区域的中指定的部分区域。
可选的，上述检测所述压力屏预先指定的多个坐标区域的坐标区域压力感应均匀度，并判断所述多个坐标区域的坐标区域压力感应均匀度是否均达到预设的坐标区域均匀度标准步骤，可以包括：
步骤a、检测所述压力屏中的预先指定的K个坐标区域的输出压力值，其中每个坐标区域的输出压力值是基于该坐标区域内的坐标点的检测压力值获取的，所述K均为大于或等于1的整数；
在本实施方式中，所述每个坐标区域的输出压力值是给予该坐标区域内的坐标点的检测压力值获取的，其中，相邻2×2个坐标点围成一个对应的坐标区域。根据该坐标区域对应的4个坐标点的检测压力值获取各坐标点的压力系数，如某一坐标点的压力系数为该坐标点的检测压力值与N×M个坐标点的检测压力值的几何平均值的比值。
根据该坐标区域对应的4个坐标点与该区域内任意一点的线性关系，可通过该坐标区域对应的4个坐标点压力系数计算得到该坐标区域的压力系数。例如：如图5所示，坐标点A、B、C和D为坐标区域对应的4个坐标点，坐标点G为该坐标区域内的任意一点。根据坐标点A、B、C、D和G的线性关系，经过坐标点G作平行于坐标点A和C之间的对角线的延长线，则该延长线与坐标点A和B之间的连线相交点为坐标点E，该延长线与坐标点B和C之间的连线相交点为坐标点F，从而通过坐标点A和B的线性关系可以计算得到坐标点E和F的压力系数，再由坐标点E和F线性关系可以计算得到坐标点G的压力系数，该压力系数即为该区域的压力系数。假如坐标点A的压力系数为3，坐标点B的压力系数为5，且E点在坐标点A和B之间连线的1/4处，则该区域的压力系数可以按照如下计算方式获得：压力系数＝3+(5-3)×1/4＝3.5。
根据所述坐标区域的压力系数与该坐标区域的原始数据计算得到该坐标 区域的输出压力值，例如：所述坐标区域的输出压力值可以为所述坐标区域的压力系数与原始数据的乘积，其中，该坐标区域的原始数据为对该区域任意一点进行打点时，线性拟合各所述压力传感器检测的初始压力值获得所述坐标区域的原始数据。
其中，所述预先指定的K个坐标区域分别选取k1个位于所述压力屏中间位置且敏感度高的坐标区域和k2个位于所述压力屏边缘位置且敏感度弱的坐标区域，所述k1和所述k2均为大于或等于1的整数，且k1+k2＝K。当对k1个坐标区域和k2个坐标区域分别以相同压力进行打点时，根据各坐标区域的压力系数和各所述压力传感器拟合得到的原始数据获得对应的输出压力值。
例如：如图6所示，选取5个敏感度高的坐标区域和2个敏感度低的坐标区域，即k1＝5，k2＝2，如敏感度高的坐标区域为坐标区域1、2、3、4和5，且坐标区域1、2、3、4和5的压力系数分别为P5(1)、P5(2)、P5(3)、P5(4)和P5(5)；敏感度低的坐标区域为坐标区域6和7，且坐标区域6和7的压力系数分别为P2(1)和P2(2)。假设以相同压力击打每个坐标区域时，对于坐标区域1、2、3、4、5、6和7，所述压力传感器拟合得到的原始数据分别为Q1、Q2、Q3、Q4、Q5、Q6和Q7，则坐标区域1、2、3、4、5、6和7的输出压力值分别为Q1×P5(1)、Q2×P5(2)、Q3×P5(3)、Q4×P5(4)、Q5×P5(5)、Q6×P2(1)和Q7×P2(2)。
步骤b、判断所述K个坐标区域的输出压力值是否均达到预设的坐标区域均匀度标准；
在本实施方式中，所述判断所述K个坐标区域的输出压力值是否均达到预设的坐标区域均匀度标准，可以根据每个坐标区域的输出压力值相对目标压力值的误差是否处于最大误差范围内进行判断，其中，所述目标压力值为k1个压力屏中间位置且敏感度强的坐标区域的输出压力值的算术平均值。敏感度高的坐标区域与敏感度低的坐标区域所允许的最大误差不同，且敏感度高的坐标区域允许的最大误差小于敏感度低的坐标区域允许的最大误差。
例如：如图4所示，目标压力值P＝[Q1×P5(1)+Q2×P5(2)+Q3×P5(3)+Q4×P5(4)+Q5×P5(5)]/5，则可以计算得到坐标区域1、2、3、 4、5、6和7的输出压力值相对目标压力值的误差分别为[Q1×P5(1)-P]/P、[Q2×P5(2)-P]/P、[Q3×P5(3)-P]/P、[Q4×P5(4)-P]/P、[Q5×P5(5)-P]/P、[Q6×P2(1)-P]/P和[Q7×P2(2)-P]/P。假设敏感度高的坐标区域所允许的最大误差为20％，敏感度低的坐标区域所允许的最大误差为40％，判断7个坐标区域的输出压力值是否均达到预设的坐标区域均匀度标准。若[Q1×P5(1)-P]/P、[Q2×P5(2)-P]/P、[Q3×P5(3)-P]/P、[Q4×P5(4)-P]/P和[Q5×P5(5)-P]/P均小于或者等于20％，[Q6×P2(1)-P]/P和[Q7×P2(2)-P]/P均小于或者等于40％，则说明7个坐标区域的输出压力值均达到预设的坐标区域均匀度标准。
步骤c、若所述K个坐标区域的输出压力值均达到预设的坐标区域均匀度标准，则确定所述K个坐标区域的坐标区域压力感应均匀度均达到所述坐标区域均匀度标准。
在本实施方式中，当所述k1个敏感度高的坐标区域的输出压力值相对目标压力值的误差均小于或等于敏感度高的坐标区域的所允许的最大误差，且所述k2个敏感度低的坐标区域的输出压力值相对目标压力值的误差均小于或等于敏感度低的坐标区域的所允许的最大误差时，则所述K个坐标区域的输出压力值均达到预设的坐标区域均匀度标准，可以确定所述K个坐标区域的坐标区域压力感应均匀度均达到所述坐标区域均匀度标准。
例如：如图6所示，同样假设敏感度高的坐标区域所允许的最大误差为20％，敏感度低的坐标区域所允许的最大误差为40％，坐标区域1、2、3、4和5的误差[Q1×P5(1)-P]/P、[Q2×P5(2)-P]/P、[Q3×P5(3)-P]/P、[Q4×P5(4)-P]/P和[Q5×P5(5)-P]/P均小于或者等于20％，且坐标区域6和7的误差[Q6×P2(1)-P]/P和[Q7×P2(2)-P]/P均小于或者等于40％。当所述k1个敏感度高的坐标区域中至少一个坐标区域的输出压力值相对目标压力值的误差大于敏感度高的坐标区域的所允许的最大误差，或者所述k2个敏感度低的坐标区域中至少一个坐标区域的输出压力值相对目标压力值的误差大于敏感度低的坐标区域的所允许的最大误差时，则可以确定所述K个坐标区域的坐标区域压力感应均匀度未均达到所述坐标区域均匀度标准。
步骤S304、若所述多个坐标区域的坐标区域压力感应均匀度均达到所述 坐标区域均匀度标准，则确定所述压力屏为良品；
在本实施方式中，当所述k1个敏感度高的坐标区域的输出压力值相对目标压力值的误差均小于或等于敏感度高的坐标区域的所允许的最大误差，且所述k2个敏感度低的坐标区域的输出压力值相对目标压力值的误差均小于或等于敏感度低的坐标区域的所允许的最大误差时，所述K个坐标区域的输出压力值均达到预设的坐标区域均匀度标准，确定所述K个坐标区域的坐标区域压力感应均匀度均达到所述坐标区域均匀度标准，则确定所述压力屏为良品。
步骤S305、若所述压力屏的压力传感器不工作正常，或者所述坐标点压力感应均匀度未达到所述坐标点均匀度标准，则确定所述压力屏为不良品。
在本实施例中，若所述压力感应均匀度未达到所述均匀度标准，则确定所述压力屏为不良品，包括：
若所述多个坐标点的坐标点压力感应均匀度未均达到所述坐标点均匀度标准，或者所述多个坐标区域的坐标区域压力感应均匀度未均达到所述坐标区域均匀度标准，则确定所述压力屏为不良品。
在本实施方式中，当所述压力屏的压力传感器不正常工作，如：按压时存在至少一个亮点未消失，则确定所述压力屏为不良品，则需要对所述压力屏进行校准或者维修；
或者，若所述坐标点压力感应均匀度未均达到所述坐标点均匀度标准，如所述N×M个坐标点中至少一个坐标点的检测压力值最大的坐标点的检测压力值是大于预设的最大检测压力值或者所述至少一个预先指定坐标点的检测压力值未达到预设的均匀度标准，则确定所述压力屏为不良品，则需要对所述压力屏进行校准或者维修；
或者，若所述坐标区域压力感应均匀度未均达到所述坐标区域均匀度标准，如所述k1个敏感度高的坐标区域中至少一个坐标区域的输出压力值相对目标压力值的误差大于敏感度高的坐标区域的所允许的最大误差，或者所述k2个敏感度低的坐标区域中至少一个坐标区域的输出压力值相对目标压力值的误差大于敏感度低的坐标区域的所允许的最大误差时，则确定所述压力屏为不良品，则需要对所述压力屏进行校准或者维修。
其中，对于压力屏的校准，可以通过调节所述压力传感器使每个坐标点的压力系数达到预设的参考压力系数。
当然，该实施方式中，同样可以应用到图1所示的实施例中，且能达到相同有益效果。本实施例中，在图1所示的基础上增加了多种可选的实施方式，都可以对压力屏进行检测，从而可以判断压力屏是否为良品。
