具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
以下结合附图，详细说明本申请各实施例提供的技术方案。
参照图1所示，为本申请实施例提供的指纹操作提示方法的步骤示意图，该方法主要包括以下步骤：
步骤11：检测显示装置是否接收到指纹识别指令。
在本申请中，可通过在显示装置中设置接触式传感器，用于实时监测显示装置是否接收到指纹识别指令。这里的显示装置，是指在屏下设置有指纹识别模块的显示装置，例如，可以是全面屏手机或是平板电脑。其中，指纹识别指令可以是由触摸操作触发的，也可以是由声控、或其他终端设备发送的指令触发的，所述触摸操作可以是针对显示装置实施的任意方式的触摸操作；例如，触摸操作可以是：拿起显示装置的操作、对显示装置的屏幕或按键的单指或多指按压操作、对显示装置的旋转操作、对显示装置的摇一摇操作等操作中的任意一种。
步骤12：当检测到针对显示装置实施的触摸操作时，在预设目标区域内动态显示用于提示指纹操作的第一图像；其中，所述预设目标区域位于所述显示装置的显示区域内。
在本申请中，只有检测到针对显示装置实施的触摸操作，才在预设目标区域内显示用于提示指纹操作的第一图像，从而，不需要该预设目标区域一直显示，节省功耗；而且，是在预设目标区域内动态显示该第一图像，避免了静态显示造成的图像残影，保证了显示画面的品质。
可选地，在本申请中，步骤12可具体包括：按照预设显示规则，控制所述预设目标区域内的发光子像素动态显示用于提示指纹操作的第一图像。其中，所涉及的第一图像可以是显示装置在出厂时设置的，也可以是根据用户的选择通过应用程序选取的，被作为指纹LOGO使用。本申请并不对此进行限定。
需要说明的是，所述预设显示规则，与所述第一图像的类型相关；当第一图像为静态图形时，预设显示规则可以为：第一图像的静态图形不变，灰度交替变化；当第一图像为动态图形时，预设显示规则可以为：第一图像的动态图形变化，和/或，灰度也变化；当第一图像为可移动图片时，预设显示规则可以为：第一图像中的可移动图片从预设目标区域的一侧移入，从相对另一侧移出。
下面介绍本申请所涉及的三种动态显示方案。
第一图像为静态图形
本申请中，按照预设显示规则，控制所述预设目标区域内的发光子像素动态显示用于提示指纹操作的第一图像，具体包括：控制点亮所述预设目标区域内用于显示静态图形的发光子像素，周期性更新所述静态图形交替显示不同颜色。其实，在具体实现时，系统根据静态图形的轮廓确定需要点亮的发光子像素，并控制这些发光子像素点亮，显示静态图形；同时，会按照预设周期更新该静态图形的灰度，使得该静态图形交替显示不同色彩。
具体地，参照图2(a)所示，方框所限定区域为显示装置内显示区域的预设目标区域，第一图像为圆形图案；假设第一图像每隔1s更新一种颜色，每个周期内更新4次，那么可存在：
第1s显示时，该圆形图案区域的发光子像素均设置为255,0,0；该圆形图案显示红色，图2(a)中以左斜条纹表示显示色彩为红色；
第2s显示时，该圆形图案区域的发光子像素均设置为0,255,0；该圆形图案显示绿色，图2(a)中以右斜条纹表示显示色彩为绿色；
第3s显示时，该圆形图案区域的发光子像素均设置为0,0,255；该圆形图案显示蓝色，图2(a)中以方格表示显示色彩为蓝色；
第4s显示时，该圆形图案区域的发光子像素均设置为255,255,0；该圆形图案显示黄色，图2(a)中以倾斜网格表示显示色彩为黄色；如此循环交替更新圆形图案的发光颜色，其实，也可以在第1s时显示任一一种颜色，第2s时不显示颜色，然后在第3s时显示任一一种颜色，第4s时不显示颜色，从而，以呼吸灯的方式，形成提示用户指纹区域所在位置的指纹提示LOGO。
再如，参照图2(b)所示，方框所限定区域为显示装置内显示区域的预设目标区域，第一图像为环形图案，即可以理解为将方框区域对应的发光子像素等分为16份，其中，位于方框边缘区域的发光子像素1-发光子像素12对应显示环形图案；那么，发光子像素1-发光子像素12可以按照图2(a) 的方式交替显示不同颜色，也可以每隔1s显示一次颜色：
第1s显示时，该环形图案区域的发光子像素均设置为255,0,0；该环形图案显示红色，图2(b)中以左斜条纹表示显示色彩为红色；
第2s显示时，该环形图案区域的发光子像素关闭，并不显示；
第3s显示时，该环形图案区域的发光子像素均设置为0,0,255；该环形图案显示蓝色，图2(b)中以方格表示显示色彩为蓝色；
第4s显示时，该环形图案区域的发光子像素关闭，并不显示；如此循环开启或关闭环形图案的发光子像素，开启时的发光子像素的颜色可以不变，也可以交替更新。从而，以呼吸灯的方式，形成提示用户指纹区域所在位置的指纹提示LOGO。
第一图像为动态图形
本申请中，按照预设显示规则，控制所述预设目标区域内的发光子像素动态显示用于提示指纹操作的第一图像，具体包括：确定所述预设目标区域内限定的多个子区域以及所述动态图形的所有画面帧图形，所述每个子区域对应有相应数量的发光子像素；控制点亮所述预设目标区域内用于显示动态图形的任一画面帧图形的发光子像素；根据所述动态图形的所有画面帧图形的显示顺序，依次更新点亮用于显示下一个画面帧图形的发光子像素。
其中，画面帧图形是指：每帧显示的图形，而本申请中的可能存在多个相同的画面帧图形，在进行显示时，仅选取不同的画面帧图形即可。对于选取的多个画面帧图形，按照一定的周期交替显示各个画面帧图形。
具体地，参照图3(a)所示，方框所限定区域为显示装置内显示区域的预设目标区域，第一图像为交替变化的点阵图案，即可以理解为将方框区域对应的发光子像素等分为16份，其中，位于方框边缘区域的发光子像素1-发光子像素12对应显示交替变化的点阵图案；那么，发光子像素1-发光子像素12可以按照图3(a)的方式交替显示不同的画面帧图形，仍以交替时间为1s为例：
第1s显示时，依次将发光子像素1、发光子像素3、发光子像素5、发光子像素7、发光子像素9、发光子像素11的灰度设置为255，其他发光子像素处于关闭状态，即灰度设置为0；
第2s显示时，依次将发光子像素2、发光子像素4、发光子像素6、发光子像素8、发光子像素10、发光子像素12的灰度设置为255，其他发光子像素处于关闭状态，即灰度设置为0；
第3s显示时，依次将发光子像素3、发光子像素5、发光子像素7、发光子像素9、发光子像素11、发光子像素1的灰度设置为255，其他发光子像素处于关闭状态，即灰度设置为0；如此循环反复形成兼具呼吸灯式以及跑马灯式的指纹提示LOGO。
再如，参照图3(b)所示，方框所限定区域为显示装置内显示区域的预设目标区域，第一图像为交替变化的环形图案，即可以理解为将方框区域中对应一圆形图案的发光子像素等分为7份，其中，由圆形图案的中心至边缘共划分为7个大小不一的环形图案对应的发光子像素：发光子像素1-发光子像素7。那么，发光子像素1-发光子像素7可以按照图3(b)的方式由中心向边缘依次显示大小不一的环形图案，仍以交替时间为1s为例：
第1s显示时，将发光子像素1的灰度设置为255，其他发光子像素处于关闭状态，即灰度设置为0；
第2s显示时，将发光子像素2的灰度设置为255，其他发光子像素处于关闭状态，即灰度设置为0；
第3s显示时，将发光子像素3的灰度设置为255，其他发光子像素处于关闭状态，即灰度设置为0；
第4s显示时，将发光子像素4的灰度设置为255，其他发光子像素处于关闭状态，即灰度设置为0；如此循环反复形成兼具呼吸灯式以及跑马灯式的指纹提示LOGO。
其实，在每次交替显示不同的环形图案时，也可以同时更新颜色，形成 一种炫彩的效果。
第一图像为可移动图片
其中，所述第一图像可以包含至少一幅可移动图片；本申请中，按照预设显示规则，控制所述预设目标区域内的发光子像素动态显示用于提示指纹操作的第一图像，具体包括：根据所述至少一幅可移动图片进入预设目标区域的方向和速度，依次控制点亮所述预设目标区域相应界面内的相应发光子像素；所述至少一幅可移动图片从所述预设目标区域的任意一侧进入，从与进入的一侧相对而设的一侧移出。该第一图像虽然涉及到图片的移动，但是，实质上也是控制发光子像素点亮而实现的动态显示。
具体地，参照图4(a)所示，方框所限定区域为显示装置内显示区域的预设目标区域，第一图像为一幅静态或动态图片，该图片可以按照预先规定的移动规则，从预设目标区域的底部移入，穿过预设目标区域后并从预设目标区域的顶部移出，从而，形成可动态显示的指纹提示LOGO。其实，也可以从左侧移入，从右侧移出。
图4(b)所示，可以为两幅可移动图片，按照预先规定的移动规则，一幅可移动图片从预设目标区域的左侧移入，另一幅可移动图片从预设目标区域的右侧移入，两幅可移动图片的移动速度相同，并在相遇后分别返回从各自移入的一侧移出，从而，形成可动态显示的指纹提示LOGO。其实，在本申请中，两幅可移动图片在相遇后，可以分别继续前进，重叠显示并分别从对方的移入侧移出。此外，还可以选择以其他角度移入或移出，本申请并不对此进行限定。
需要说明的是，以上所涉及到的发光子像素的划分方式以及交替更新时间，可以根据系统的设置项选择或是根据用户的需求进行灵活设定。
由上述技术方案可知，通过呼吸灯或是跑马灯的显示方式，在预设目标区域动态显示用于提示用户的指纹提示LOGO，这样的显示方式，可以避免预设目标区域的发光子像素一直显示静态图像而导致的残影问题，而且，本 申请通过动态显示的方式，使得发光子像素不会长时间显示一种灰度，在一定程度上减少了发光子像素的发光时长，缓解发光子像素的老化问题。
可选地，在本申请中，当第一图像为可移动图片时，所述第一图像为通过显示装置的操作系统输入的可移动图片或由驱动芯片利用算法生成的可移动图片，本申请并不对此进行限定。
可选地，在本申请中，在预设目标区域动态显示第一图像之后，用户可以根据提示图像在预设目标区域内进行指纹识别。但是，预设目标区域并不是一直动态显示第一图像，那么，为了节约电池耗电以及缓解发光子像素的老化，该方法还包括：当检测到在预设目标区域内动态显示用于提示指纹操作的第一图像的持续时长超过预设阈值时，结束显示。具体实现时，以拿起手机作为触发动态显示提示图像的条件，当提示指纹识别位置的第一图像动态显示超过20s，仍未在预设目标区域进行指纹识别操作，那么，该第一图像就会消失，即结束显示该第一图像。当再次希望进行指纹识别时，可通过拿起手机以外的触发条件触发。
参照图5所示，为本申请提供的显示面板的模块示意图，该显示面板主要包括：
检测模块51，用于检测显示装置是否被实施触摸操作。
显示模块52，用于当检测到针对显示装置实施的触摸操作时，在预设目标区域内动态显示用于提示指纹操作的第一图像；其中，所述预设目标区域位于所述显示装置的显示区域内。
可选地，所述显示模块52在预设目标区域内动态显示用于提示指纹操作的第一图像时，具体用于：按照预设显示规则，控制所述预设目标区域内的发光子像素动态显示用于提示指纹操作的第一图像。
由上述技术方案可知，通过显示模块控制预设目标区域的发光子像素，采用呼吸灯或是跑马灯等方式，动态显示用于提示用户的指纹提示LOGO，从而，可以避免预设目标区域的发光子像素一直显示静态图像而导致的残影 问题，而且，本申请通过动态显示的方式，使得发光子像素不会长时间显示一种灰度，在一定程度上减少了发光子像素的发光时长，缓解发光子像素的老化问题。
同时，本申请还提出了一种显示装置，该显示装置包括所述的显示面板。此外，该显示装置可以为手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪、智能穿戴设备等任何具有显示功能的产品或部件。对于该显示装置的其它必不可少的组成部分均为本领域的普通技术人员应该理解具有的，在此不做赘述，也不应作为对本申请的限制。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
