步骤101,在检测到屏幕的第一区域的图像将发生变化的情况下,获取所述第一区域的第一图像数据。
第一区域可以是需要进行图像更新的区域,例如,第一区域可以是屏幕上的状态栏所在区域,状态栏上显示有时间,消息提示,电量,网络流量情况等等。电子设备的处理器可以对屏幕显示的图像进行实时监测,监测是否需要更新屏幕某个区域显示的图像。第一图像数据即在检测到第一区域的图像将发生变化的情况下,第一区域对应的更新数据。举例来说,对于屏幕上显示的时间,若时间显示为X时Y分Z秒,则该时间需要每秒钟更新一次,相应地,第一区域可以是时间所在位置的区域,第一图像数据是时间的更新数据。
步骤102,将所述第一图像数据发送给所述屏幕,以使所述屏幕利用所述第一图像数据对所述第一区域的图像进行更新,所述屏幕对所述屏幕中除所述第一区域之外的第二区域不更新。也就是说,在屏幕的局部区域发生变化时,SOC发送局部区域的图像给屏幕,屏幕仅更新局部区域内的像素。

在本申请一种实施例中,所述方法还包括:在所述第二区域的图像未更新的时长超过预设时长的情况下,获取所述第二区域的第二图像数据;
将所述第二图像数据发送给所述屏幕,以使所述屏幕利用所述第二图像数据对所述第二区域的图像进行更新。
具体地,所述预设时长为所述屏幕的最低刷新频率对应的时长。屏幕的像素在不刷新的情况下,亮度会逐渐减少,会导致闪烁问题,因此屏幕的像素需要以一定频率进行刷新,刷新的频率大于或等于屏幕像素不会出现闪烁问题的最小频率。例如,以低温多晶氧化物(Low Temperature Polycrystalline Oxide,LTPO)屏为例,LTPO屏最低刷新频率可以做到 1Hz,即预设时长为1秒,LTPO屏每1秒需要更新一次,来保证屏幕像素的亮度正常。
第二图像数据可以是最近一次对第二区域显示的图像进行更新的数据,该数据可以存储在屏幕的存储器中,屏幕在更新时可以从该存储器中取出数据进行更新,也可以是由SOC将第二图像数据发送给屏幕,例如,在所述第二区域的图像未更新的时长超过预设时长的情况下,SOC将第二区域的位置信息和第二图像数据发送给屏幕,屏幕采用第二图像数据对第二区域的图像进行更新。需要说明的是,在将所述第二图像数据发送给所述屏幕的情况下,还将第二区域的位置信息也发送给屏幕。
在本实施例中,对第二区域的图像进行更新,以避免第二区域的像素长时间未更新导致闪烁的问题。在第二区域的图像未更新的时长小于预设时长的情况下,第二区域的像素不更新也不会出现闪烁问题。通过上述步骤,可以对第二区域的显示图像采用屏幕的最低刷新频率进行更新,可以在保障屏幕的显示性能的同时,减少第二区域的更新次数,从而减少电子设备的功耗,节省电子设备的电量,提高电子设备的续航能力。
在本申请一种实施例中,所述获取所述第一区域的第一图像数据,包括:
获取所述屏幕的第一更新数据;
在所述第一更新数据为目标对象的更新数据的情况下,获取所述屏幕中所述目标对象所在的第一区域;
根据所述第一区域确定第一图像数据,所述第一图像数据包括所述第一更新数据。
具体地,电子设备的处理器会对屏幕进行监测,以确定是否有数据需要更新,若电子设备的处理器获取到更新数据,且该更新数据为目标对象的更新数据,则获取第一区域,第一区域包括目标对象在屏幕中所占的区域,例如,第一区域可以是目标对象的最小外接矩形。在确定第一区域之后,可以根据第一区域中的第一子区域和第二子区域,确定第一图像数据,其中,第一子区域为目标对象所占区域,第二子区域为第一区域中除目标对象所占区域之外的区域,相应地,第一图像数据包括第一子区域对应的 更新数据,以及第二子区域对应的更新数据,第一子区域对应的更新数据为电子设备获取的第一更新数据,第二子区域对应的更新数据为第二更新数据,第二更新数据可采用第二子区域最近一次更新所采用的数据。
举例来说,若目标对象为屏幕上显示的时间,第一区域为状态栏所在区域,电子设备获取到的第一更新数据为对时间进行更新的更新数据,第一图像数据包括第一更新数据和第二更新数据,第一更新数据用于更新时间所在区域的像素,第二更新数据用于更新状态栏区域中除时间之外的其他区域的像素,第二更新数据若无变化,可以采用最近一次更新所采用的数据。
上述步骤中,通过第一更新数据确定目标对象,并根据目标对象所在的第一区域,确定第一图像数据,并对第一区域采用第一图像数据进行更新,可以减小屏幕中图像更新的范围,节省电子设备的功耗,提高电子设备的续航能力。
在本申请又一实施例中,所述将所述第一图像数据发送给所述屏幕,包括:
将所述第一图像数据和所述第一区域的位置信息传输给所述屏幕,使得所述屏幕利用所述第一图像数据对所述第一区域的图像进行更新。
在确定第一图像数据和第一区域之后,可以将第一图像数据和第一区域的位置信息发送给屏幕,第一区域的位置信息可以是第一区域在屏幕上的位置坐标,第一区域可以为矩形,第一区域的位置信息可以是该矩形的左上角坐标和右下角坐标。
以分辨率为1080*2400的屏幕,屏幕为LTPO屏为例进行说明,以屏幕左上角为坐标原点(0,0)建立如图2a所示的直角坐标系,右下角坐标(1079,2399),状态栏矩形区域1的坐标为(0,0,1079,79),其中(0,0)为矩形区域1的左上角坐标,(1079,79)为矩形区域1的右下角坐标,图2a中标号2所示为时间所在区域。
如图2b所示,电子设备的处理器可将第一图像数据和第一区域的位置信息即状态栏矩形区域坐标(0,0,1079,79)传输给屏幕,屏幕在收到第一图像数据后,利用LTPO低帧率的特性,可以只更新状态栏区域的像素 (0,0,1079,79),而无需更新屏幕所有像素。
上述步骤中,将所述第一图像数据和所述第一区域的位置信息传输给所述屏幕,并控制所述屏幕利用所述第一图像数据对所述第一区域显示的图像进行更新,可以减小屏幕中图像更新的范围,节省电子设备的功耗。
以下以前述LTPO屏为例进行说明,由于仅更新了状态栏区域(0,0,1079,79)的像素,屏幕其他区域长时间不更新会导致闪烁问题,电子设备需要实时判断出状态栏以外的区域(0,80,1079,2399)是否1秒未更新,若是则发送命令给屏幕,屏幕收到命令后更新一次状态栏以外的区域,以保证屏幕显示正常。
以状态栏的更新频率为60HZ为例,若每次更新都是对屏幕全部区域进行更新,则屏幕1秒内需要更新所有(1080x2400)像素60次,即1秒累计更新像素量为1080*2400*60=155520000,使用本申请提供的方案,屏幕1秒内更新状态栏(1080*80)区域像素60次,非状态栏区域(1080*2320)一次,1秒累计更新像素量为:1080*80*60+1080*2320=5184000+2505600=7689600,大幅减少了像素更新量。
图2c所示为本申请实施例提供的屏幕更新方法的流程示意图,如图2c所示,包括如下步骤:
步骤201,手机处理器监测屏幕的局部区域是否需要变化,若否,转步骤202执行;若是,转步骤203执行;
步骤202,更新整个屏幕;
步骤203,处理器发送局部区域的更新数据和局部区域的坐标给屏幕;
步骤204,屏幕仅更新局部区域内的像素;
步骤205,处理器判断屏幕局部区域以外的像素是否超过LTPO最低刷新频率的时间,若否,转步骤201执行,若是,转步骤206执行;
步骤206,处理器发送局部区域以外其他区域的图像更新数据和其他区域的坐标给屏幕;
步骤207,屏幕仅更新所述其他区域内的像素,并转步骤201执行。
上述过程中,SOC实时检测屏幕的画面更新情况,动态更新LTPO屏的图像数据,控制屏幕像素局部更新,在保证显示正常的情况下,可有效 减少像素更新的范围和次数,节省屏幕功耗,达到提高手机续航的目的。
