Description

图像显示方法及装置 技术领域
本发明涉及显示技术领域，尤其涉及图像显示方法及装置。
背景技术
有机发光二极管(Organic Light-Emitting Diode，简称OLED)是一种由电极及有机材料涂层构成的薄膜多层器件。由于OLED显示屏具有自发光、低功耗、可视角度大等特性，因此越来越多的移动终端制造者选择由OLED构成的OLED显示屏作为移动终端的显示装置。
移动终端的显示装置在显示图像的过程中，通常需要长时间显示解锁界面、应用图标、虚拟按键等固定图像。受制于OLED的显示原理，如果OLED显示屏某个区域长时间显示固定图像，就需要该区域的灰阶电压长时间维持在一个固定值，从而会造成该区域有机材料涂层的亮度衰减速度不同于其他区域。而显示屏不同区域的亮度衰减速度不同则会造成显示屏在切换显示不同图像时产生屏幕残像。例如，由于显示解锁界面中解锁按钮图像与解锁背景图像灰阶不同，在显示屏长时间显示解锁界面后再切换显示纯色图像时，会因为用于显示解锁按钮图像的区域与用于显示解锁背景的区域亮度衰减速度不同，而在纯色图像上留下解锁界面的残像。
由此可以看出，OLED显示屏采用现有图像显示方式显示图像，很容易产生屏幕残像，影响OLED显示屏的显示效果。

具体实施方式
为了使本领域技术人员更好地理解本发明方案，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地描述，显然，所述描述的实施例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。
在本发明实施例中，功能性图像是指终端在接收到用户对该图像的操作后会做出相应响应的图像，所述响应可以是执行与该图像相应程序或显示与该图像相应的信息等。例如，所述功能性图像可以是解锁按钮、应用图标、虚拟按键、通知栏、时间指示器等。
在本发明实施例中，背景图像是指终端在接收到用户对该图像的操作后，不做出响应的图像。例如，所述背景图像可以是壁纸、界面背景、解锁背景等。
在本发明实施例中，目标区域是指显示屏中图像显示固定的目标区域。例如，所述目标区域可以是显示屏中用于显示虚拟按键区域、通知栏区域等显示的图像长时间不发生变化的区域。
参见图1，为本发明实施例提供的图像显示方法的流程图。
步骤101，确定显示屏中图像显示固定的目标区域。
终端首先确定显示屏中图像显示固定的目标区域。根据实际需求的不同，终端可以采用灰阶识别、区域识别等不同的方式确定所述目标区域。
由于OLED显示屏或有源矩阵有机发光二极体(Active-matrix organic light emitting diode，简称AMOLED)显示屏等在显示不同图像时，各像素的灰阶电压各不相同。因此终端可以采用灰阶识别方式，利用各个像素灰阶电压来检测出显示屏中用于显示固定图像的目标区域。
在一种实现方式中，由于显示屏在显示固定图像时，显示屏各个像素的灰阶电压是与该固定图像相应的预定灰阶电压。因此，终端可以检测所述显示屏各个像素的灰阶电压；选择灰阶电压为预定电压值的像素所构成的第一区域作为所述目标区域。
例如，如图2所示，以终端是手机为例，在终端在显示九宫格解锁界面时，解锁界面包括背景图像及解锁按钮图像，由于背景图像及解锁按钮图像的灰度均为特定 值，因此用于显示背景图像的屏幕像素的灰阶电压为第一预设电压，用于显示解锁按钮图像的屏幕像素灰阶电压为第二预设电压。终端可以获取显示屏各个像素的灰阶电压；进而可以判定灰阶电压为第一预设电压的像素所构成的区域即为显示背景图像的区域，并判断灰阶电压为第二预设电压的像素所构成的区域即为显示解锁按钮图像的区域。灰阶电压为第一预设电压的像素所构成的区域与灰阶电压为第二预设电压的像素所构成的区域相结合就构成了用于显示固定图像的目标区域。
在另一种实现方式中，由于在显示固定图像时，显示屏用于显示固定图像的各个像素的灰阶稳定，并且稳定的灰阶电压会维持较长一段时间。因此终端也可以检测所述显示屏各个像素的灰阶电压持续时间；选择所述灰阶电压持续时间超过预设时间阈值的像素所构成的第二区域作为所述目标区域，其中，预设时间阈值可以根据需要进行设置。
例如，显示屏在显示应用内容时，会有部分区域所显示的图像随应用内容而发生变化，但是仍会有部分区域显示的图像不随应用画面发生变化，图像不随应用画面发送变化的区域包括虚拟按键区域、通知栏等区域等。也就是说，显示屏中会有部分区域内像素的灰阶电压变化较为频繁，而另一部分区域内像素的灰阶电压则持续稳定。因此当终端检测到某些像素的灰阶电压持续稳定超过预定时间阈值时，例如超过30秒时，则可以认为这些像素所构成的区域即为用于显示固定图像的目标区域。
由于在显示某些用户界面时，显示屏的特定区域显示的必然是固定图像。因此，终端也可以直接显示屏的将预设区域作为所述目标区域。
例如，如图3所示，当所述显示屏显示应用菜单界面时，通常会有一部分区域用于显示用户界面中的虚拟按键，并且显示屏只要是在显示屏显示应用菜单界面，无论其他区域所显示的图像发生任何变化，用于显示虚拟按键的虚拟按键区域均会显示虚拟按键及背景图像而不发生变化。因此，终端可以首先判断显示屏是否在显示应用菜单界面，当显示屏在显示应用菜单界面时，终端可将显示屏中用于显示虚拟按键的预设区域作为目标区域。
此外，由于显示屏在显示游戏界面或视频播放等时，也可能会出现部分区域显示的内容长时间不发生变化的情况。为防止在此情况下，调整图像显示方式给用户使用带来不便，终端可以先判断显示屏是否在显示特定用户界面，当所述显示屏显示所述特定用户界面时，再确定显示屏中图像显示固定的目标区域。其中，所述特定用户界面可以是解锁界面或应用菜单界面等。
例如，终端可以先判断显示屏是否在显示应用菜单界面；在判定显示屏正在显示应用菜单界面时，再执行确定显示屏中图像显示固定的目标区域的步骤。当判定显示屏不在显示应用菜单界面，如判定显示屏正在显示游戏界面或视频播放界面时，终端可以不执行确定显示屏中图像显示固定的目标区域的步骤。
步骤102，获取所述目标区域中显示的指定图像。
在目标区域确定后，终端也可以首先获取显示屏所显示的整体图像，然后从整体图像中选取出在目标区域中显示的图像作为指定图像。或者终端也可以根据目标区域的各个像素的灰阶电压、电流等还原出指定图像。
例如，当显示屏显示九宫格解锁界面时，所述目标区域通常是整个显示屏，在此情况下，终端可以直接将显示屏所显示的整个图像作为指定图像。又如，当显示屏显示应用菜单界面时，所述目标区域可以是显示虚拟按键的区域，在此情况下，终端可以将所述虚拟按键图像作为指定图像。
步骤103，以分别对所述指定图像中不同区域独立进行灰阶调整的方式，调整所述指定图像在所述显示屏上的显示方式。
根据指定图像的不同，终端可以采用不同的调整方式对分别对所述指定图像中不同区域独立进行灰阶调整，以避免所述目标区域内各个像素的灰阶电压长时间不发生变化，从而降低显示屏出现屏幕残像可能性。
在一种可能的实现方式中，当所述指定图像由功能性图像和背景图像构成时，终端可以首先从所述指定图像中识别出功能性图像及背景图像；然后周期性对调所述功能性图像与所述背景图像的灰阶，从而避免目标区域各个像素的灰阶电压长时间不发生变化。
例如，所述指定图像为九宫格解锁界面时，所述九宫格解锁界面通常由解锁按钮图像与解锁背景构成。由于解锁按钮图像与解锁背景的灰阶不同，因此终端可以根据灰阶首先从所述解锁界面中识别解锁背景及解锁按钮图像；然后周期性对调解锁背景及解锁按钮的灰阶。当解锁按钮灰阶为255，解锁背景灰阶为0的时候，终端在所述目标区域交变显示以解锁按钮灰阶为255解锁背景灰阶为0的九宫格解锁界面，及解锁按钮灰阶为0解锁背景灰阶为255的九宫格解锁界面，即，终端可以按照周期交变显示图4与图5所示的九宫格解锁界面。
为进一步弱化OLED的残影效应，更好的防止屏幕残像，终端可以首先将所述 功能性图像的灰阶设置为第一预设灰阶，并将所述背景图像的灰阶设置为第二预设灰阶；然后再周期性对调解锁背景及解锁按钮的灰阶。其中，当所述功能性图像的灰阶高于所述背景图像的灰阶时，功能性图像的灰阶高于第一预设灰阶，第一预设灰阶高于第二预设灰阶，第二预设灰阶高于背景图像的灰阶；当所述功能性图像的灰阶低于所述背景图像的灰阶时，功能性图像的灰阶低于第一预设灰阶，第一预设灰阶低于第二预设灰阶，第二预设灰阶低于背景图像的灰阶。
例如，当图标灰阶为255，背景灰阶为0时，终端可以首先将解锁按钮的灰阶设置为100，并将背景的灰阶设置为200；然后终端可以一个周期将解锁按钮的灰阶调整为200，并将解锁背景的灰阶调整为100；然后在下一个周期将解锁按钮的灰阶调整为100，并将解锁背景的灰阶调整为200。
在另一种可能的实现方式中，终端也可以预先生成与所述指定图像相对应的备用图像；终端在周期性调整所述指定图像在所述显示屏上的显示方式时，可以获取与所述指定图像相对应的备用图像；并在所述目标区域周期交替显示所述指定图像及所述备用图像。其中，所述备用图像可以由终端对所述指定图像进行灰阶翻转生成，也可以有终端在识别出所述指定图像及所述功能性图像后，调整所述功能性图像在所述显示屏的位置后生成，或者也可以由终端以其他方式生成。
例如，当指定图像如图6所示时，终端可以对图6所示的图像进行灰阶翻转，生成如图7所示的备用图像，然后在所述目标区域周期性交变显示图6所示的图像与图7所示的图像。
又如，当指定图像如图6所示时，终端也可以识别出指定图像中的时间指示等功能性图像，然后调整所述功能性图像之间的相对位置，生成如图8所示的备用图像，然后在在所述目标区域周期性交变显示图6所示的图像与图8所示的图像。
又如，当指定图像如图6所示时，终端也可以在所述目标区域周期性交变显示图6所示的图像与全黑图像，即，终端可以微动(Fine Motion)方式显示所述指定图像。
在另一种可能的实现方式中，终端可以周期性调整所述指定图像在所述显示屏上的显示位置；或者首先从所述指定图像中识别出功能性图像及背景图像，然后周期性调整所述功能性图像相对于所述背景图像的显示位置。
以所述指定图像是九宫格解锁界面为例，终端可以首先识别出解锁按键图像及 解锁背景图像，然后在第一个显示周期以图9所示的位置显示所述解锁按键图像，在第二个显示周期以图10所示的方式显示所述解锁按键图像，在第三个显示周期以图11所示的方式显示所述解锁按键图像，并在第四个显示周期以图12所示的方式显示所述解锁按键图像，并依此顺序循环往复。
在另一种可能的实现方式中，终端也可以首先识别出指定图像中功能性图像的轮廓线；然后将所述轮廓线两侧指定数量像素的灰阶设置为第三预设灰阶。在此基础上，终端还可以周期性对功能性图像的灰阶、背景图像的灰阶及第三预设灰阶进行调整。
例如，终端可以首先识别出指定图像中功能性图像的轮廓线，然后为所述轮廓线两侧指定数量的像素分别设置不同的灰阶电压，从而达到该指定数量像素所构成的图案呈现出从功能性图像的灰阶逐渐过渡到背景图像灰阶的显示效果。在此基础上，还可以周期性对调功能性图像与背景图像的灰阶，并对应调整第三预设灰阶，以保证该指定数量像素所构成的图案仍呈现出从功能性图像的灰阶逐渐过渡到背景图像灰阶的显示效果
在本实施例中，终端可以确定显示屏中图像显示固定的目标区域；获取所述目标区域中显示的指定图像；周期性调整所述指定图像在所述显示屏上的显示方式。采用本实施例，终端可以周期性调整所述指定图像在所述显示屏上的显示方式，从而可以避免显示屏中目标区域长时间显示所述指定图像，减轻因为指定图像在所述显示屏上显示时间过长造成所述显示屏产生屏幕残像。
参见图13，为本发明实施例提供的图像显示装置结构示意图。
