具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白,以下结合具体实施例,并参照附图,对本发明进一步详细说明。
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、完整地描述,显然,所描述的实施例仅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。
图1为本申请的实施例中的显示设备的结构框图。如图1所示,本申请对实施例提供一种显示设备,其包括:发光组件集合,包括多个发光组件子集,每个发光组件子集包括至少一个发光组件,多个发光组件子集对应显示设备的不同显示子区域;
显示组件集合,其用于对应显示图像,显示组件集合位于发光组件集合的照射范围内,包括多个对应发光组件子集的显示组件子集,每个显示组件子集至少包括一个显示组件;
其中,显示一帧图像时,多个发光组件子集按照第一模式发光,多个显示组件子集按照第二模式显示,第一模式与第二模式匹配,以使对应的发光组件子集和显示组件子集能匹配。
也就是,发光组件集合包括多个发光组件,多个发光组件划分为多组,形成多个发光组件子集(每个发光组件子集中可以仅包括一个发光组件,也可包括多个发光组件),每一个(或每多个)发光组件子集与显示设备的一个显示子区域相对应,也可同时与相邻于该一个显示子区域的部分显示子区域相对应,也就是,每一个或每多个发光组件子集的照射范围可不完全覆盖相邻的两个显示子区域。显示组件集合位于发光组件集合的照射范围内,也就是,显示组件集合与发光组件集合前后对应设置。显示组件集合包括至少一个或两个显示组件,该至少一个或两个显示组件划分为一组或多组,形成至少两个显示组件子集。
上述显示组件集合即为显示屏幕的全部显示区域,显示子区域为显示屏幕的整个显示区域的一部分,其具体划分方式以及具体位置及面积均不固定,该显示子区域并非由用户或制造商真实定义出来的,也不是通过程序等虚拟出来的,其仅是一种意识。本申请中对于显示子区域的概念的提出只是为了体现本申请在显示图像时并非如现有技术中一样采用使发光组件集合内的发光组件同时发光,且使显示组件集合内的显示组件同时显示的方式,而是发光组件集合与显示组件集合可以分区域依次匹配的进行发光和显示。例如可以认为每个显示组件子集均与一个显示子区域相对应,或者为每多个显示组件子集与一个显示子区域相对应。但是,每一个(或每多个)发光组件子集均需有一个唯一的显示组件子集(或唯一的一组由多个显示组件子集形成的子集组)与其相对应,该种设置方式是为了保证每个显示子区域对应的发光组件均是固定的,故该对应的发光组件的发光模式以及显示子区域的显示模式也就是固定的。当显示设备在显示一帧图像时,令每个发光组件子集均按照第一模式发光,每个显示组件子集均按照与第一模式相匹配的第二模式进行显示,便可使得相对应的发光组件子集与显示组件子集相匹配,进而保证画面的整体显示效果。
其中,上述的按照第一模式发光包括对进入发光状态的控制、对进入保持发光状态的控制和/或对进入结束发光状态的控制。
另外,上述的显示区域不仅可为显示屏幕的整体,还可为显示屏幕的部分,也即一部分显示屏幕所对应区域为本实施例中的显示区域。例如将显示屏幕分为上中下三部分,其中某一部分或某两部分形成为实施例中的 显示区域。然而,需注意的是,当显示区域为显示屏幕整体的时候,该第一模式的发光不包括多个发光组件子集同时进入发光状态的模式。但是当显示区域仅为部分显示屏幕对应区域时,该第一模式的发光便包括多个发光组件子集同时进入发光状态的模式。
例如,图2为本申请的实施例中的显示设备中纵向设置的显示组件集合的设置结构图,该图中仅示出了显示组件,图中编号1指代的是显示组件,具体为像素。如图2所示,显示设备具有光源和多个像素,其中多个像素构成显示组件集合,该多个像素位于光源的照射范围内,以通过光源发出的光而完成对应画面的显示。所有像素划分为多个像素组,每一个(或多个)像素组形成一个显示组件子集。光源为多个LED灯,所有LED灯构成发光组件集合,每个LED灯即为一个发光组件,将所有LED灯分为多组(可平均分配也可不均匀分配,具体视显示设备的具体结构形状而定,例如显示屏幕并非为规则形状,或显示屏幕虽然整体呈矩形,但顶角处为圆弧形等,因此会使LED灯分配不均),每组LED灯均构成一个发光组件子集。
显示组件子集与发光组件子集间前后对应设置,以使每个(或每多个)显示组件子集均至少有一个发光组件子集(或由多个发光组件子集配合形成的一组发光组件子集)与其对应,为其提供光源。在显示设备显示一帧图像时,各像素组与LED灯组按照相互匹配的模式分别进行显示和发光,以使得相对应的像素组与LED灯组能够匹配,提高了显示设备的显示精度以及显示效果,同时也提高了用户的观看体验。
进一步地,上述对应的发光组件子集和显示组件子集能匹配具体包括:
处于发光状态的发光组件子集照射的显示组件子集均处于显示状态,如显示同一图像的局部;和/或
每个显示组件子集处于显示状态时,如显示图像的局部时,对应的发光组件子集均处于发光状态。
也就是,以发光组件子集的角度来看,显示设备中只要是处于发光状态的发光组件子集,其对应的显示组件子集当前均处于显示状态,且各个显示组件子集当前显示的图像内容均属于同一帧图像。例如将视频流中各帧图像均对应不同的显示子区域而划分为多块,当与多个显示子区域中的 某几个显示子区域对应的发光组件子集处于发光状态时,该某几个显示子区域则按照视频流各帧图像的播放顺序而依次对应显示各帧图像的局部。且位于同一时间或同一帧图像的显示周期内,各显示子区域显示的图像内容均属于同一帧图像的内容(其中各显示子区域与显示组件子集间的关系已在上述内容中介绍,此处不再赘述),即,在同一帧图像的显示周期内,各显示子区域共同配合显示该同一帧图像,每个显示子区域仅显示该同一帧图像的部分内容。需提出的是,本实施例中在同一帧图像的显示周期内,并不一定要所有显示子区域均进行显示,可以仅部分显示子区域参与图像的显示,也就是显示设备显示每帧图像时不一定要显示该帧图像的全部,而是可以仅显示部分,但是需要保证的是,只要是位于该帧图像的显示周期内参与显示的各显示子区域,其显示的图像内容一定属于该帧图像。
而同样地,若以显示组件子集的角度来看,即为,在同一帧图像的显示周期内均在执行显示动作的显示组件子集对应的发光组件子集均处于发光状态,进而保证显示设备在同一帧图像的显示周期内仅显示该同一帧图像(包括该帧图像的整体或局部),而在下一帧图像的显示周期内仅显示该下一帧图像的整体或局部,以此类推,进而有效避免现有技术中的画面拖尾现象,即在处于第一帧图像的显示周期内时,显示设备经常会由于光源的发光与像素的显示不匹配而显示该第一帧图像的前一帧或后一帧图像,并因此解决现有技术中画面错乱,严重影响用户观看的技术问题。
进一步地,本申请实施例中的显示组件子集包括的均为显示组件集合中连续设置的多个显示组件,多个发光组件子集与显示组件子集匹配设置,当显示组件集合在显示图像时,显示图像是由多个显示组件子集有序地显示对应的局部图像得到的。也就是,显示组件子集中的显示组件是有序设置的,例如是依次相邻设置的,则显示组件形成的多个显示组件子集以及与显示组件子集设置形式匹配的发光组件子集也是有序设置的,例如同样是依次相邻设置的。当显示设备显示图像时,该图像的各部分便可按照多个显示组件子集的排列顺序进行有序显示,进而形成一帧完整图像(如上所述也有可能是不完整图像,但是至少有序显示的显示内容均属于同一帧图像)。本实施例中采用该种设置方式的原因,也即,将多个连续设置的显示组件形成一显示组件子集的原因是为了易于与发光组件对应设置,保 证该显示组件子集中的所有显示组件均能够与同一发光组件子集相对应,进而为后续保证对应的发光组件子集与显示组件子集间相匹配奠定基础,辅助实现显示设备能够对图像进行流畅显示的技术效果。例如显示设备具有四行像素(每一个像素为一个显示组件),每一行像素均形成一个显示组件子集,即,显示设备共有四个显示组件子集,四个显示组件子集分别对应四个依次相邻的显示子区域,在设置发光组件子集时可对应各显示子区域均设置一个发光组件子集。发光组件子集可选用任一种器件形式,例如单独光源,或光源和光学器件(比如导光板)的组合;也可以选任一种发光原理的器件,比如电光面板(ELP)、发光二极管(LED)、冷阴极管(CCFL)等。另外,采用上述选择连续设置的显示组件形成显示组件子集的方式还能够在发光组件的数量小于显示组件数量的情况下,便于依据对应关系选择连续的显示子区域依次进行显示,保证显示的流畅性。例如,继续上述实施例,可在相邻两个显示子区域间设置一发光组件子集,也即,相邻两个显示组件子集与同一发光组件子集相对应。
但是,倘若将分散的多个显示组件构成一显示组件子集,仍以显示设备具有四行像素为例,例如将该四行像素中每行像素中位于行首、行中以及行尾的几个像素组合形成一显示组件子集,由于各像素点位置过于分散,就会导致发光组件的设置形式单一,只能通过对应各像素处均设置一点光源来实现。而且,由于各像素组件子集中像素点位置分散,还会使得形成的各显示子区域在显示图像时因无明显次序而稍显凌乱,效果不及上述实施例中多个显示组件子集依次连续显示图像的效果。
进一步地,为了保证对应的显示组件子集与发光组件子集相匹配,多个发光组件子集的发光顺序需与多个显示组件子集的显示顺序相匹配。也就是,各发光组件子集的设置顺序与显示组件子集的设置顺序相匹配。本申请现结合以下两个具体实施例来详细说明显示组件子集与发光组件子集间的设置关系:
实施例一:
多个显示组件子集沿纵向依次设置;
多个发光组件子集分别对应多个显示组件子集沿纵向依次设置;
第一模式与第二模式匹配包括:发光组件子集沿纵向依次发光,显示 组件子集沿纵向依次显示。
例如,继续结合图2所示,以一组像素为一个显示组件子集为例,显示设备包括多组像素,该多组像素沿竖直方向从上到下依次设置,每个像素组中的像素均沿水平方向从左到右依次设置。以发光组件子集为一组LED灯为例,发光组件集合包括多组LED灯,该多组LED灯组沿竖直方向从上到下依次设置,每一组(或多组)LED灯均与一个(或多个)像素组相对应。每个LED灯组中的LED灯同样均沿水平方向由左到右依次设置。其中,每组LED灯中的LED灯的设置数量以及相邻两个LED灯间的距离不固定,其可与对应的显示组件子集中的像素一一对应也可为一个LED灯与多个像素对应。当显示一帧图像时,多组LED灯由上到下逐行被点亮(位于同一排的LED灯同时被点亮,即同时进入发光状态),多个像素组也同样由上到下依次进入显示状态,以显示对应的图像画面(同一行的像素同时进入显示状态)。
再以发光组件子集为一导光板及用于点亮导光板的光源(以下均简称发光组件子集为一导光板)为例(其中的光源设置在与导光板端部相对的位置处,其可为一个也可为两个),如图3所示,图3为本申请的一实施例中的显示设备中纵向设置的发光组件集合的设置结构图,该图中仅示出了发光组件,图中编号2指代的是发光组件,具体为导光板,编号3指代的是导光板两端分别设置的用于点亮导光板的光源,该光源可设置一个也可设置两个。具体地,多个发光组件子集分别对应多个像素组沿竖直方向从上到下依次设置。在显示一帧图像时,倘若上述发光组件子集与显示组件子集为一一对应的关系,那么多个发光组件子集也即多个导光板从上到下依次进入发光状态,多个像素组也同样从上到下依次进入显示状态。而若对应关系为每多个相邻的发光组件子集与一个显示组件子集对应,或每多个相邻的显示组件子集与一个发光组件子集对应。那么,多个发光组件子集按照多个显示组件子集从上到下的排列顺序依次进入发光状态,多个显示组件子集从上到下依次进入显示状态,其中对应同一个显示组件子集的发光组件子集同时进入发光状态;或多个发光组件子集按照从上到下的顺序依次进入发光状态,多个显示组件子集按照发光组件子集进入发光状态的顺序依次进入显示状态,其中对应同一个发光组件子集的显示组件子 集同时进入显示状态。
其中,发光组件子集也可为一根或多根灯管,例如图4,其为本申请的另一实施例中的显示设备中纵向设置的发光组件集合的设置结构图,该图中仅示出了发光组件,图中编号2指代的是发光组件。如图4所示,多根灯管由上到下排列并形成多个发光组件子集,在进行显示时,多个发光组件子集有序地依次进入发光状态。
继续结合图2、图3和图4所示,图中的发光组件或显示组件经多条虚线进行划分,以分别形成各个发光组件子集或显示组件子集,然而实际中,该虚线是不存在的,本实施例中示出该虚线仅用于辅助理解本实施例的技术方案。
实施例二:
多个显示组件子集沿横向依次设置;
多个发光组件子集分别对应多个显示组件子集沿横向依次设置;
第一模式与第二模式匹配包括:多个发光组件子集沿横向依次进入发光状态,多个显示组件子集沿横向依次进入显示状态。
例如,图5为本申请的另一实施例中的显示设备中横向设置的发光组件集合的设置结构图,图中仅示出了发光组件,图中编号2指代的是发光组件,具体为导光板,3指代的是用于点亮导光板的光源。结合图5所示,以一组像素为一个显示组件子集为例,显示设备包括多组像素,该多组像素沿水平方向从左到右依次设置,每个像素组中的像素均沿竖直方向从上到下依次设置。以发光组件子集为一导光板为例(也可为一根或多根灯管),多个发光组件子集分别对应多个像素组(对应关系可为一一对应,也可为每多个相邻的发光组件子集与一个像素组对应,或每多个相邻的像素组与一个发光组件子集对应),多个导光板沿水平方向从左到右依次设置。在显示一帧图像时,多个发光组件子集,也即多个导光板从左到右依次进入发光状态,多个像素组也同样从左到右依次进入显示状态。根据不同的对应关系,各导光板与各像素组的具体动作顺序可参考上一实施例。
图6为本申请的另一实施例中的显示设备中横向设置的显示组件集合的设置结构图,图中仅示出了显示组件,图中编号1指代的是显示组件,具体为像素。如图6所示,显示组件集合包括多个像素,用户以主观意识 利用虚线将该多个像素进行划分,以在从左到右的方向上形成多个像素组,每个像素组形成一个显示组件子集。发光组件集合包括多组LED灯,该多组LED灯沿水平方向从左到右依次设置,每一组(或多组)LED灯均与一个(或多个)像素组相对应。每个LED灯组中的LED灯同样均沿竖直方向由上到下依次设置。其中,每组LED灯中的LED灯的设置数量以及相邻两个LED灯间的距离不固定,其可与对应的显示组件子集中的像素一一对应,也可为一个LED灯与多个像素对应。当显示一帧图像时,多组LED灯由左到右逐行被点亮(位于同一排的LED灯同时被点亮,即同时进入发光状态),多个像素组也同样由左到右依次显示对应的图像画面(位于同一列的像素同时进入显示状态,以显示对应的图像画面)。
实施例三,本实施例是在前两种实施例的基础上进行的改变,具体地,上述两种实施例均采用的是依次逐行显示图像画面,而本实施例中采用的为“隔行”或为“隔区域”显示图像画面的方式。例如,本实施例继续以实施例一为例进行描述。图7为本申请的另一实施例中的显示设备进行隔行显示时显示组件子集与发光组件子集的状态图,图中仅示出了部分显示组件和发光组件,图中编号1指代的是发光组件,具体为导光板,图中2指代的是显示组件,具体为像素。如图7所示,在竖直方向上处于奇数位的发光组件子集首先按从上到下的顺序依次点亮。与该奇数位的发光组件子集对应的显示组件子集则同样按从上到下的顺序依次进行显示,也即,图中A、C、E对应部分在宏观角度上为预先显示;之后,处于偶数位的发光组件子集再按从上到下的顺序依次点亮,对应的显示组件子集则也同样按从上到下的顺序依次进行显示,以此达到隔区域显示的效果,也即,图中B、D对应部分在宏观角度上为再后显示。而若为“隔行”显示时,应是图中A中的五行像素中,奇数行像素由上到下依次显示,其中位于同一行的像素在宏观角度上为同时显示,与A对应的导光板可对应三个奇数行的像素的显示而连续点亮三次,也可一直保持点亮状态,直至A中三个奇数行的像素显示完毕才熄灭。A中的三个奇数行像素显示完成后接着是B中的五行像素中,偶数行像素由上到下依次显示。对应B的导光板或者对应两个偶数行的像素的显示而连续点亮两次,或者一直保持点亮状态,直至B中两个偶数行的像素显示完毕才熄灭。之后是图中C中的五行像素 中,奇数行像素由上到下依次显示,与C对应的导光板按照上述与A对应的导光板的亮灭方式运行。待C中的奇数行像素显示完毕后,D中的偶数行像素按照由上到下依次显示,与D对应的导光板按照上述与B对应的导光板的亮灭方式运行。最后E中奇数行像素由上至下依次显示,与E对应的导光板按照上述与A对应的导光板的亮灭方式运行,直至E中奇数行像素全部显示完毕,与E对应的导光板熄灭时,与A对应的导光板再次被点亮,此时A中偶数行像素由上到下依次显示,对应的导光板可随偶数行像素的显示而连续点亮两次,也可始终保持点亮状态,直至A的偶数行像素显示完毕熄灭。接着由B中奇数行像素、C中偶数行像素、D中奇数行像素及E中偶数行像素均由上至下依次显示,而分别对应B、C、D、E的导光板同样按照上述方式或连续点亮多次,或始终保持点亮状态,直至对应的像素行显示完毕再熄灭。如此,所有像素及导光板便均配合完成了画面的显示。而当为“逐行”显示时,就是A中的五行像素逐行显示之后,B中的五行像素逐行显示,之后是C、D、E中的五行像素分别依次逐行显示。相应地,与A对应的导光板在A中的五行像素进行显示时,导光板可对应各行像素的显示而连续点亮五次,或者在A中的五行像素的显示过程中始终保持点亮状态,同理,分别与B、C、D、E对应的导光板也同样按此方式运行。进一步地,本实施例的显示组件子集与发光组件子集为一一对应的关系,当显示组件子集与发光组件子集为多对一的关系时,例如每相邻两个显示组件子集与同一个发光组件子集相对应时,则当奇数位的显示组件子集从上到下依次显示时,所有发光组件子集也同样从上到下依次显示,之后奇数位的显示组件子集停止显示,发光组件子集此时可继续发光,也可重新由上到下依次发光,对应的,偶数位的发光组件子集再由上到下依次进行显示。同理,实施例二中的显示设备在显示图像时也可为隔行或隔区域显示,具体方式同上,只是发光顺序以及显示顺序为由左至右。
图11为现有技术中电子设备的一显示状态的波形图,图中标号1表示显示组件子集的动作波形,2代表发光组件子集的动作波形。如图11所示,现有技术中显示组件子集与发光组件子集间,发光组件子集不论是某一发光时刻还是任一发光时刻均与对应的显示组件子集的显示时刻不匹 配,且每一次的显示组件子集持续显示的时长与对应的发光组件子集持续发光的时长均不匹配,例如,图中t时刻,分别对应a、b、c点处的发光组件子集均为持续发光状态,而分别对应a、b、c点处的显示组件子集却分别为持续显示状态、刚进入显示状态和停止显示状态,也即,相对应的发光组件子集与显示组件子集间完全不匹配,因此导致该电子设备在进行画面显示时总是出现画面拖尾现象,导致用户的观看效果欠佳。
为有效改善上述技术问题,本申请为了保证对应的显示组件子集与发光组件子集相匹配,进而保证显示设备的显示效果,除了需要保证多个发光组件子集与显示组件子集的发光与显示顺序相匹配外,还需要保证发光组件子集的发光时间参数与显示组件子集的显示时间参数相匹配,具体地:
实施例一,图8为本申请的另一实施例中的显示设备的一种显示状态的波形图,图中1代表显示组件子集的动作波形,2代表发光组件子集的动作波形。如图8所示,显示组件子集的第一次或任意一次显示时刻与对应的发光组件子集的第一次或任意一次发光时刻相匹配。也即,相比现有技术,本实施例的电子设备在显示画面的过程中至少有一次显示组件子集的显示时刻与发光组件子集的发光时刻相匹配,而其他次的显示时刻与发光时刻并不一定相匹配。例如显示组件子集为一组像素,与该显示组件子集对应的发光组件子集为一导光板及用于点亮导光板的光源(以下均简称发光组件子集为一导光板),当显示设备欲显示一帧图像时,导光板被第一次点亮的时刻像素组也正处于第一次显示的时刻,也即,导光板第一次刚被点亮时,像素组刚刚进行第一次显示。而其中的“第一次”也可为显示组件子集与发光组件子集在所有点亮时刻与显示时刻中的任意一次。
实施例二,显示组件子集的每一次显示时刻与对应的发光组件子集的每一次发光时刻均相匹配。也就是,多个发光组件子集按照预设次序依次被点亮时,与该刚被点亮的发光组件子集对应的显示组件子集也恰好刚进行显示。如此,便可保证,不论循环多少次(例如在显示视频流时,每显示一帧图像,发光组件子集与显示组件子集便分别进行一次发光和显示,如此形成一次循环),每个发光组件子集每一次刚被点亮时,与其对应的显示组件一定恰好刚进行对应次的显示。本实施例相比现有技术,彻底避免了显示组件子集的显示时刻与发光组件子集的发光时刻不匹配的问题 发生。
实施例三,图9为本申请的另一实施例中的显示设备的一种显示状态的波形图,图中1代表显示组件子集动作波形,2代表发光组件子集动作波形。如图9所示,对应的显示组件子集的第一次或任意一次的进行显示的时长(即保持显示状态的时长)与发光组件子集的第一次或任意一次进行发光的时长(即保持发光状态的时长)相匹配。也即,相比现有技术,本实施例的电子设备在显示画面的过程中至少有一次显示组件子集保持显示状态的时间与发光组件子集保持发光状态的时间相匹配,而其他次显示时两个时间并不一定相匹配。例如,仍以实施例一中的场景为例,导光板第一次(或任意一次)被点亮后保持发光状态的时长与对应的像素组第一次(或任意一次)保持显示的时长相匹配。
实施例四,对应的显示组件子集的第一次或任意一次的进行显示的时刻以及时长与发光组件子集的第一次或任意一次进行发光的时刻以及时长均相匹配。也就是,相比现有技术,本实施例的电子设备在显示画面的过程中至少有一次显示组件子集开始进行显示的时刻与保持显示的时长均与发光组件子集对应次进行发光的时刻与保持发光的时长相匹配,而其他次二者可不相匹配。例如仍以实施例一中所示场景为例,由实施例一可知,导光板第一次(或任意一次)发光的时刻与像素组第一次(或任一次)显示的时刻相匹配。但是为了进一步提高显示效果,使得导光板在本次保持发光状态的时间里对应的像素组不仅均处于显示状态,而且保持显示状态的时间与导光板保持发光状态的时间相等,就需要如本实施例中一样,需同时限制导光板在第一次(或任一次)保持发光状态的时长与像素组在第一次(或任一次)保持显示状态的时长相匹配,从而实现上述技术效果,避免像素组已结束显示状态,而导光板却仍处于发光状态,或相反地,导光板已结束发光状态,但像素组却仍处于显示状态的现象发生。
实施例五,对应的显示组件子集的每一次保持显示状态的时长与发光组件子集的每一次保持发光状态的时长相匹配。也就是每个发光组件子集保持发光状态的时间均与对应的显示组件子集保持显示状态的时间相等。例如,同样以实施例一中的例子为例,即为每块导光板的单次发光时长均与对应的像素组的对应次显示时长相等。也即,本实施例相比现有技术, 彻底避免了显示组件子集每次保持显示的时间与发光组件子集每次保持发光的时间不匹配的问题发生。
实施例六,对应的发光组件子集的发光频率与显示组件子集的显示频率相匹配。以显示组件子集为一组像素为例,该像素组在进行显示时是按照一定频率进行的,每一次显示均显示一帧图像,其通过按照显示频率能够依次进行多次显示从而实现后多帧图像的连续显示。也可认为是像素组的像素每刷新一次,便开始显示下一帧图像。其中,需注意的是,由于每个显示组件子集均具有多个像素,每个像素的显示频率在理想状态下是相等的,然而在实际应用中却很难达到,因此,本实施中在此提到的显示频率为平均显示频率。进一步地,以发光组件子集为导光板(或一组LED灯、一根或多根灯管等)为例,其也并非持续性发光,而是配合像素的显示频率同样按照一定频率间歇性发光。故,若要使得对应的发光组件子集和显示组件子集能够相匹配,避免出现现有技术中在导光板被点亮时,对应的像素组并未进行显示,而导致的显示滞后现象的发生;或避免出现现有技术中在导光板结束发光时,对应的像素组却开始进入显示状态,如开始显示下一帧图像,而导致的黑屏现象的发生,也就是避免出现图11中分别对应a、b、c三点的显示组件子集与发光组件子集间显示与发光不匹配的现象发生,就需要使发光组件子集的发光频率和对应的显示组件子集的显示频率相匹配,即,发光组件子集不仅发光时间与对应的显示组件子集的显示时间相匹配,且发光组件子集停止发光的时间与对应的显示组件子集停止显示的时间也相匹配,以保证在发光组件子集进行发光时,对应的显示组件子集进行显示,而发光组件子集停止发光时,对应的显示组件子集停止显示。
实施例七,图10为本申请的另一实施例中的显示设备的一种显示状态的波形图,图中虚线箭头所指的波形代表发光组件子集的动作波形,位于发光组件子集的动作波形上方的波形代表显示组件子集的动作波形。如图10所示,对应的发光组件子集的发光时刻与显示组件子集的显示时刻匹配,同时发光组件子集的单次发光时长与对应的显示组件子集的单次显示时长相匹配。
具体地,为了保证在各发光组件子集进入发光状态时,与各进入发光 状态的发光组件子集对应的各显示组件子集同时恰好进入显示状态(如正在显示第一帧图像或完成刷新并开始显示第二帧图像),即,各显示组件子集每次开始显示的时刻与对应的发光组件子集每次开始发光的时刻均相匹配,就需要使各发光组件子集的波形曲线和对应的显示组件子集的波形曲线的时间起点相同,且发光组件子集的每个发光周期的时间起点需要与对应的显示组件子集的整数倍个显示周期的时间起点相同。也就是,发光组件子集的发光频率与对应的显示组件子集的显示频率可相等,也可为倍数(需为整数倍)关系。而若要同时避免在发光组件子集结束发光时,对应的显示组件子集却开始显示下一帧图像而导致的黑屏现象的发生,就需要在满足上述关系的同时使发光组件子集的单次发光时长(保持发光状态的时长)与对应的显示组件子集的单次显示时长(保持显示状态的时间)相匹配。使得发光组件子集的每个发光周期的波形与对应的显示组件子集的每整数个显示周期的波形一一对应,保证各显示组件子集在每一次刷新图像后均能够充分显示,且显示周期与对应发光组件子集的发光周期匹配,彻底避免了显示的画面出现内容不匹配现象或黑屏现象。也即,图10所示的电子设备完全克服了图11所示的电子设备包含的显示与发光不匹配的技术问题。
另外,需指出的是,本申请上述各实施例中指出的同一显示组件子集内的显示组件同时显示画面,以及对应的发光组件子集中的发光组件同时发光,也即二者相匹配均是从宏观角度来看的。例如一块导光板对应多行像素,二者动作相匹配是从宏观角度上而言的。而若以微观角度来看,本申请中相对应的显示组件子集与发光组件子集相匹配则为显示组件子集中第一个进行显示的显示组件与发光组件子集中第一个发光的显示组件相匹配。也即,继上述举例内容,导光板与第一行第一个像素相匹配。
进一步地,本实施例中的显示设备还包括检测装置和处理装置,用于使电子设备在进行显示调节时能够自适应调整,也就是使电子设备能够对自身的显示模式和发光模式等进行自适应调整,以使得其显示效果更佳。而为了适配具有不同设置类型的发光组件及显示组件的电子设备,本实施例中的检测装置和处理装置的具体配置方式不唯一,具体如下:
第一种配置方式:
检测装置可用于检测发光组件子集的设置形式,如检测多个发光组件子集是纵向排列设置还是横向排列设置;
处理装置可用于根据检测装置的检测结果确定与各发光组件子集对应的显示组件子集的组成形式,如确定哪些显示组件形成与各发光组件子集对应的显示组件子集。
本实施例中的处理装置可应用于在发光组件子集的设置位置以及发光顺序固定时,来根据发光组件子集的发光形式确定出与各发光组件子集对应的显示组件子集,以及显示组件子集的显示顺序。而该发光形式的信息可从预置的存储装置中读取设备的型号或参数,当然,具体的获取方式不唯一,也可为通过人工输入等通道获取。具体地,当发光组件集合为多排(多列)灯管或导光板(也可为一片LED灯),显示组件集合为一片像素时,检测装置检测到每排灯管或导光板均形成一发光组件子集,且其发光模式为由上至下时,处理装置则根据检测结果来确定出如何将该多个像素进行划分,以形成多个用于和发光组件子集相对应的显示组件子集。例如包括四块由上至下依次设置的导光板,分别形成四个发光组件子集,处理装置则将多个像素分为四组,以分别形成四个显示组件子集,该四个显示组件子集同样由上至下依次排列设置,每一个显示组件子集均与唯一一个发光组件子集相对应。当然,倘若显示组件较多时,还可令相邻两个或多个显示组件子集均与一发光组件子集相对应。
第二种配置方式:
检测装置可用于检测显示组件子集的显示策略,例如,显示组件子集以何种方式进行显示,多个显示组件子集是由上至下依次显示还是从左到右依次显示;
处理装置可用于确定与各显示组件子集对应的发光组件子集的组成形式。同上。
本实施例中的处理装置可应用于在显示组件子集的设置位置以及发光顺序固定时,来根据显示组件子集的显示形式而确定出与各显示组件子集对应的发光组件子集,以及发光组件子集的发光顺序。而该显示形式的信息可从预置的存储装置中读取设备的型号或参数,当然,具体的获取方式不唯一,也可为通过人工输入等通道获取。例如以发光组件集合为多排 LED灯为例,当检测装置检测到多个显示组件子集是由上到下依次显示时,处理装置则根据多个显示组件子集的设置位置以及显示顺序而对多排LED灯进行划分,使每一排或相邻的多排LED灯形成一发光组件子集,以此确定出分别与各显示组件子集对应的各发光组件子集以及该多个发光组件子集的发光顺序。
如图12所示,本申请对实施例还提供一种显示方法,包括:
获得待显示的一帧图像;
多个发光组件子集按照第一模式发光,其中,发光组件子集是发光组件集合的一部分,且每个发光组件子集包括至少一个发光组件,并对应显示设备的不同显示子区域;
多个显示组件子集按照第二模式显示,其中,显示组件子集是显示组件集合的一部分并包括多个显示组件,且显示组件集合用于对应显示图像,显示组件集合位于发光组件集合的照射范围内;
其中,第一模式与第二模式匹配,以使对应的发光组件子集和显示组件子集能匹配。
也就是,发光组件集合包括多个发光组件,多个发光组件划分为多组,形成多个发光组件子集(每个发光组件子集中可以仅包括一个发光组件,也可包括多个发光组件),每一个(或每多个)发光组件子集与显示设备的一个显示子区域相对应,也可同时与相邻于该一个显示子区域的部分显示子区域相对应,也即,每一个或每多个发光组件子集的照射范围可不完全覆盖相邻的两个显示子区域。显示组件集合位于发光组件集合的照射范围内,也就是,显示组件集合与发光组件集合前后对应设置。显示组件集合包括至少一个或两个显示组件,该至少一个或两个显示组件划分为一组或多组,形成至少两个显示组件子集。
上述显示组件集合即为显示屏幕的全部显示区域,显示子区域为显示屏幕的整个显示区域的一部分,其具体划分方式以及具体位置及面积均不固定,该显示子区域并非由用户或制造商真实定义出来的,也不是通过程序等虚拟出来的,其仅是一种意识。本申请中对于显示子区域的概念的提出只是为了体现本申请在显示图像时并非如现有技术中一样采用使发光组件集合内的发光组件同时发光,且使显示组件集合内的显示组件同时显 示的方式,而是发光组件集合与显示组件集合可以分区域依次匹配的进行发光和显示。例如可以认为每个显示组件子集均与一个显示子区域相对应,或者为每多个显示组件子集与一个显示子区域相对应。但是,每一个(或每多个)发光组件子集均需有一个唯一的显示组件子集(或唯一的一组由多个显示组件子集形成的子集组)与其相对应,该种设置方式是为了保证每个显示子区域对应的发光组件均是固定的,故该对应的发光组件的发光模式以及显示子区域的显示模式也就是固定的。当显示设备在显示一帧图像时,令每个发光组件子集均按照第一模式发光,每个显示组件子集均按照与第一模式相匹配的第二模式进行显示,便可使得相对应的发光组件子集与显示组件子集相匹配,进而保证画面的整体显示效果。
其中,上述按照第一模式发光包括对进入发光状态的控制、对进入保持发光状态的控制和/或对进入结束发光状态的控制。
另外,上述的显示区域不仅可为显示屏幕的整体,还可为显示屏幕的部分,也即一部分显示屏幕所对应区域为本实施例中的显示区域。例如将显示屏幕分为上中下三部分,其中某一部分或某两部分形成为实施例中的显示区域。然而,需注意的是,当显示区域为显示屏幕整体的时候,该第一模式的发光不包括多个发光组件子集同时进入发光状态的模式。但是当显示区域仅为部分显示屏幕对应区域时,该第一模式的发光便包括多个发光组件子集同时进入发光状态的模式。
例如,图2为本申请的实施例中的显示设备中纵向设置的显示组件集合的设置结构图,该图中仅示出了显示组件,图中编号1指代的是显示组件,具体为像素。如图2所示,显示设备具有光源和多个像素,其中光源为多个LED灯,所有LED灯构成发光组件集合,每个LED灯即为一个发光组件,将所有LED灯分为多组(可平均分配也可不均匀分配,具体视显示设备的具体结构形状而定,例如显示屏幕并非为规则形状,或显示屏幕虽然整体呈矩形,但顶角处为圆弧形等,因此会使LED灯分配不均),每组LED灯均构成一个发光组件子集。显示设备的所有像素构成显示组件集合,该多个像素位于光源的照射范围内,以通过光源发出的光而完成对应画面的显示。所有像素划分为多个像素组,每一个(或多个)像素组形成一个显示组件子集,显示组件子集与发光组件子集间前后对应设置, 以使每个(或每多个)显示组件子集均至少有一个发光组件子集(或由多个发光组件子集配合形成的一组发光组件子集)与其对应,为其提供光源。在显示设备显示一帧图像时,各像素组与LED灯组按照相互匹配的模式分别进行显示和发光,以使得相对应的像素组与LED灯组能够匹配,提高了显示设备的显示精度以及显示效果,同时也提高了用户的观看体验。
进一步地,上述对应的发光组件子集和显示组件子集能匹配具体包括:
处于发光状态的发光组件子集照射的显示组件子集均处于显示状态,如显示同一图像的局部;和/或
每个显示组件子集处于显示状态时,如显示图像的局部时,对应的发光组件子集均处于发光状态。
也就是,以发光组件子集的角度来看,显示设备中只要是处于发光状态的发光组件子集,其对应的显示组件子集当前均处于显示状态,且各个显示组件子集当前显示的图像内容均属于同一帧图像。例如将视频流中各帧图像均对应不同的显示子区域而划分为多块,当与多个显示子区域中的某几个显示子区域对应的发光组件子集处于发光状态时,该某几个显示子区域则按照视频流各帧图像的播放顺序而依次对应显示各帧图像的局部。且位于同一时间或同一帧图像的显示周期内,各显示子区域显示的图像内容均属于同一帧图像的内容(其中各显示子区域与显示组件子集间的关系已在上述内容中介绍,此处不再赘述),即,在同一帧图像的显示周期内,各显示子区域共同配合显示该同一帧图像,每个显示子区域仅显示该同一帧图像的部分内容。需提出的是,本实施例中在同一帧图像的显示周期内,并不一定要所有显示子区域均进行显示,可以仅部分显示子区域参与图像的显示,也就是显示设备显示每帧图像时不一定要显示该帧图像的全部,而是可以仅显示部分,但是需要保证的是,只要是位于该帧图像的显示周期内参与显示的各显示子区域,其显示的图像内容一定属于该帧图像。
而同样地,若以显示组件子集的角度来看,即为,在同一帧图像的显示周期内均在执行显示动作的显示组件子集对应的发光组件子集均处于发光状态,进而保证显示设备在同一帧图像的显示周期内仅显示该同一帧图像(包括该帧图像的整体或局部),而在下一帧图像的显示周期内仅显示该下一帧图像的整体或局部,以此类推,进而有效避免现有技术中的画 面拖尾现象,即在处于第一帧图像的显示周期内时,显示设备经常会由于光源的发光与像素的显示不匹配而显示该第一帧图像的前一帧或后一帧图像,并因此解决现有技术中画面错乱,严重影响用户观看的技术问题。
进一步地,本申请实施例中的显示组件子集包括的均为显示组件集合中连续设置的多个显示组件,多个发光组件子集与显示组件子集匹配设置,当显示组件集合在显示图像时,显示图像是由多个显示组件子集有序地显示对应的局部图像得到的。也就是,显示组件子集中的显示组件是有序设置的,例如是依次相邻设置的,则显示组件形成的多个显示组件子集以及与显示组件子集设置形式匹配的发光组件子集也是有序设置的,例如同样是依次相邻设置的。当显示设备显示图像时,该图像的各部分便可按照多个显示组件子集的排列顺序进行有序显示,进而形成一帧完整图像(如上所述也有可能是不完整图像,但是至少有序显示的显示内容均属于同一帧图像)。本实施例中采用该种设置方式的原因,也即,将多个连续设置的显示组件形成一显示组件子集的原因是为了易于与发光组件对应设置,保证该显示组件子集中的所有显示组件均能够与同一发光组件子集相对应,进而为后续保证对应的发光组件子集与显示组件子集间相匹配奠定基础,辅助实现显示设备能够对图像进行流畅显示的技术效果。例如显示设备具有四行像素(每一个像素为一个显示组件),每一行像素均形成一个显示组件子集,即,显示设备共有四个显示组件子集,四个显示组件子集分别对应四个依次相邻的显示子区域,在设置发光组件子集时可对应各显示子区域均设置一个发光组件子集。发光组件子集可选用任一种器件形式,例如单独光源,或光源和光学器件(比如导光板)的组合;也可以选任一种发光原理的器件,比如电光面板(ELP)、发光二极管(LED)、冷阴极管(CCFL)等。另外,采用上述选择连续设置的显示组件形成显示组件子集的方式还能够在发光组件的数量小于显示组件数量的情况下,便于依据对应关系选择连续的显示子区域依次进行显示,保证显示的流畅性。例如,继续上述实施例,可在相邻两个显示子区域间设置一发光组件子集,也即,相邻两个显示组件子集与同一发光组件子集相对应。
但是,倘若将分散的多个显示组件构成一显示组件子集,仍以显示设备具有四行像素为例,例如将该四行像素中每行像素中位于行首、行中以 及行尾的几个像素组合形成一显示组件子集,由于各像素点位置过于分散,就会导致发光组件的设置形式单一,只能通过对应各像素处均设置一点光源来实现。而且,由于各像素组件子集中像素点位置分散,还会使得形成的各显示子区域在显示图像时因无明显次序而稍显凌乱,效果不及上述实施例中多个显示组件子集依次连续显示图像的效果。
进一步地,为了保证对应的显示组件子集与发光组件子集相匹配,多个发光组件子集的发光顺序需与多个显示组件子集的显示顺序相匹配。也就是,各发光组件子集的设置顺序与显示组件子集的设置顺序相匹配。本申请现结合以下两个具体实施例来详细说明显示组件子集与发光组件子集间的设置关系:
实施例一:
多个显示组件子集沿纵向依次设置;
多个发光组件子集分别对应多个显示组件子集沿纵向依次设置;
第一模式与第二模式匹配包括:发光组件子集沿纵向依次发光,显示组件子集沿纵向依次显示。
例如,继续结合图2所示,以一组像素为一个显示组件子集为例,显示设备包括多组像素,该多组像素沿竖直方向从上到下依次设置,每个像素组中的像素均沿水平方向从左到右依次设置。以发光组件子集为一组LED灯为例,发光组件集合包括多组LED灯,该多组LED灯组沿竖直方向从上到下依次设置,每一组(或多组)LED灯均与一个(或多个)像素组相对应。每个LED灯组中的LED灯同样均沿水平方向由左到右依次设置。其中,每组LED灯中的LED灯的设置数量以及相邻两个LED灯间的距离不固定,其可与对应的显示组件子集中的像素一一对应也可为一个LED灯与多个像素对应。当显示一帧图像时,多组LED灯由上到下逐行被点亮(位于同一排的LED灯同时被点亮,即同时进入发光状态),多个像素组也同样由上到下依次进入显示状态,以显示对应的图像画面(同一行的像素同时进入显示状态)。
再以发光组件子集为一导光板及用于点亮导光板的光源(以下均简称发光组件子集为一导光板)为例(其中的光源设置在与导光板端部相对的位置处,其可为一个也可为两个),如图3所示,图3为本申请的一实施 例中的显示设备中纵向设置的发光组件集合的设置结构图,该图中仅示出了发光组件,图中编号2指代的是发光组件,具体为导光板,编号3指代的是导光板两端分别设置的用于点亮导光板的光源,该光源可设置一个也可设置两个。具体地,多个发光组件子集分别对应多个像素组沿竖直方向从上到下依次设置。在显示一帧图像时,倘若上述发光组件子集与显示组件子集为一一对应的关系,那么多个发光组件子集也即多个导光板从上到下依次进入发光状态,多个像素组也同样从上到下依次进入显示状态。而若对应关系为每多个相邻的发光组件子集与一个显示组件子集对应,或每多个相邻的显示组件子集与一个发光组件子集对应。那么,多个发光组件子集按照多个显示组件子集从上到下的排列顺序依次进入发光状态,多个显示组件子集从上到下依次进入显示状态,其中对应同一个显示组件子集的发光组件子集同时进入发光状态;或多个发光组件子集按照从上到下的顺序依次进入发光状态,多个显示组件子集按照发光组件子集进入发光状态的顺序依次进入显示状态,其中对应同一个发光组件子集的显示组件子集同时进入显示状态。
其中,发光组件子集也可为一根或多根灯管,例如图4,其为本申请的另一实施例中的显示设备中纵向设置的发光组件集合的设置结构图,该图中仅示出了发光组件,图中编号2指代的是发光组件。如图4所示,多根灯管由上到下排列并形成多个发光组件子集,在进行显示时,多个发光组件子集有序地依次进入发光状态。
继续结合图2、图3和图4所示,图中的发光组件或显示组件经多条虚线进行划分,以分别形成各个发光组件子集或显示组件子集,然而实际中,该虚线是不存在的,本实施例中示出该虚线仅用于辅助理解本实施例的技术方案。
实施例二:
多个显示组件子集沿横向依次设置;
多个发光组件子集分别对应多个显示组件子集沿横向依次设置;
第一模式与第二模式匹配包括:多个发光组件子集沿横向依次进入发光状态,多个显示组件子集沿横向依次进入显示状态。
例如,图5为本申请的另一实施例中的显示设备中横向设置的发光组 件集合的设置结构图,图中仅示出了发光组件,图中编号2指代的是发光组件,具体为导光板,3指代的是用于点亮导光板的光源。结合图5所示,以一组像素为一个显示组件子集为例,显示设备包括多组像素,该多组像素沿水平方向从左到右依次设置,每个像素组中的像素均沿竖直方向从上到下依次设置。以发光组件子集为一导光板为例(也可为一根或多根灯管),多个发光组件子集分别对应多个像素组(对应关系可为一一对应,也可为每多个相邻的发光组件子集与一个像素组对应,或每多个相邻的像素组与一个发光组件子集对应),多个导光板沿水平方向从左到右依次设置。在显示一帧图像时,多个发光组件子集,也即多个导光板从左到右依次进入发光状态,多个像素组也同样从左到右依次进入显示状态。根据不同的对应关系,各导光板与各像素组的具体动作顺序可参考上一实施例。
图6为本申请的另一实施例中的显示设备中横向设置的显示组件集合的设置结构图,图中仅示出了显示组件,图中编号1指代的是显示组件,具体为像素。如图6所示,显示组件集合包括多个像素,用户以主观意识利用虚线将该多个像素进行划分,以在从左到右的方向上形成多个像素组,每个像素组形成一个显示组件子集。发光组件集合包括多组LED灯,该多组LED灯沿水平方向从左到右依次设置,每一组(或多组)LED灯均与一个(或多个)像素组相对应。每个LED灯组中的LED灯同样均沿竖直方向由上到下依次设置。其中,每组LED灯中的LED灯的设置数量以及相邻两个LED灯间的距离不固定,其可与对应的显示组件子集中的像素一一对应,也可为一个LED灯与多个像素对应。当显示一帧图像时,多组LED灯由左到右逐行被点亮(位于同一排的LED灯同时被点亮,即同时进入发光状态),多个像素组也同样由左到右依次显示对应的图像画面(位于同一列的像素同时进入显示状态,以显示对应的图像画面)。
实施例三,本实施例是在前两种实施例的基础上进行的改变,具体地,上述两种实施例均采用的是依次逐行显示图像画面,而本实施例中采用的为“隔行”或为“隔区域”显示图像画面的方式。例如,本实施例继续以实施例一为例进行描述。图7为本申请的另一实施例中的显示设备进行隔行显示时显示组件子集与发光组件子集的状态图,图中仅示出了部分显示组件和发光组件,图中编号1指代的是发光组件,具体为导光板,图中2 指代的是显示组件,具体为像素。如图7所示,在竖直方向上处于奇数位的发光组件子集首先按从上到下的顺序依次点亮。与该奇数位的发光组件子集对应的显示组件子集则同样按从上到下的顺序依次进行显示,也即,图中A、C、E对应部分在宏观角度上为预先显示;之后,处于偶数位的发光组件子集再按从上到下的顺序依次点亮,对应的显示组件子集则也同样按从上到下的顺序依次进行显示,以此达到隔区域显示的效果,也即,图中B、D对应部分在宏观角度上为再后显示。而若为“隔行”显示时,应是图中A中的五行像素中,奇数行像素由上到下依次显示,其中位于同一行的像素在宏观角度上为同时显示,与A对应的导光板可对应三个奇数行的像素的显示而连续点亮三次,也可一直保持点亮状态,直至A中三个奇数行的像素显示完毕才熄灭。A中的三个奇数行像素显示完成后接着是B中的五行像素中,偶数行像素由上到下依次显示。对应B的导光板或者对应两个偶数行的像素的显示而连续点亮两次,或者一直保持点亮状态,直至B中两个偶数行的像素显示完毕才熄灭。之后是图中C中的五行像素中,奇数行像素由上到下依次显示,与C对应的导光板按照上述与A对应的导光板的亮灭方式运行。待C中的奇数行像素显示完毕后,D中的偶数行像素按照由上到下依次显示,与D对应的导光板按照上述与B对应的导光板的亮灭方式运行。最后E中奇数行像素由上至下依次显示,与E对应的导光板按照上述与A对应的导光板的亮灭方式运行,直至E中奇数行像素全部显示完毕,与E对应的导光板熄灭时,与A对应的导光板再次被点亮,此时A中偶数行像素由上到下依次显示,对应的导光板可随偶数行像素的显示而连续点亮两次,也可始终保持点亮状态,直至A的偶数行像素显示完毕熄灭。接着由B中奇数行像素、C中偶数行像素、D中奇数行像素及E中偶数行像素均由上至下依次显示,而分别对应B、C、D、E的导光板同样按照上述方式或连续点亮多次,或始终保持点亮状态,直至对应的像素行显示完毕再熄灭。如此,所有像素及导光板便均配合完成了画面的显示。而当为“逐行”显示时,就是A中的五行像素逐行显示之后,B中的五行像素逐行显示,之后是C、D、E中的五行像素分别依次逐行显示。相应地,与A对应的导光板在A中的五行像素进行显示时,导光板可对应各行像素的显示而连续点亮五次,或者在A中的五行像素的显示 过程中始终保持点亮状态,同理,分别与B、C、D、E对应的导光板也同样按此方式运行。进一步地,该实施例为显示组件子集与发光组件子集一一对应的关系,当显示组件子集与发光组件子集为多对一的关系时,例如每相邻两个显示组件子集与同一个发光组件子集相对应时,则当奇数位的显示组件子集从上到下依次显示时,所有发光组件子集也同样从上到下依次显示,之后奇数位的显示组件子集停止显示,发光组件子集此时可继续发光,也可重新由上到下依次发光,对应的,偶数位的发光组件子集再由上到下依次进行显示。同理,实施例二中的显示设备在显示图像时也可为隔行或隔区域显示,具体方式同上,只是发光顺序以及显示顺序为由左至右。
图11为现有技术中电子设备的一显示状态的波形图,图中标号1表示显示组件子集的动作波形,2代表发光组件子集的动作波形。如图11所示,现有技术中显示组件子集与发光组件子集间,发光组件子集不论是某一发光时刻还是任一发光时刻均与对应的显示组件子集的显示时刻不匹配,且每一次的显示组件子集持续显示的时长与对应的发光组件子集持续发光的时长均不匹配,例如,图中t时刻,分别对应a、b、c点处的发光组件子集均为持续发光状态,而分别对应a、b、c点处的显示组件子集却分别为持续显示状态、刚进入显示状态和停止显示状态,也即,相对应的发光组件子集与显示组件子集间完全不匹配,因此导致该电子设备在进行画面显示时总是出现画面拖尾现象,导致用户的观看效果欠佳。
为有效改善上述技术问题,本申请为了保证对应的显示组件子集与发光组件子集相匹配,进而保证显示设备的显示效果,除了需要保证多个发光组件子集与显示组件子集的发光与显示顺序相匹配外,还需要保证发光组件子集的发光时间参数与显示组件子集的显示时间参数相匹配,具体地:
实施例一,图8为本申请的另一实施例中的显示设备的一种显示状态的波形图,图中1代表显示组件子集的动作波形,2代表发光组件子集的动作波形。如图8所示,显示组件子集的第一次或任意一次显示时刻与对应的发光组件子集的第一次或任意一次发光时刻相匹配。也即,相比现有技术,本实施例的电子设备在显示画面的过程中至少有一次显示组件子集的显示时刻与发光组件子集的发光时刻相匹配,而其他次的显示时刻与发 光时刻并不一定相匹配。例如显示组件子集为一组像素,与该显示组件子集对应的发光组件子集为一导光板及用于点亮导光板的光源(以下均简称发光组件子集为一导光板),当显示设备欲显示一帧图像时,导光板被第一次点亮的时刻像素组也正处于第一次显示的时刻,也即,导光板第一次刚被点亮时,像素组刚刚进行第一次显示。而其中的“第一次”也可为显示组件子集与发光组件子集在所有点亮时刻与显示时刻中的任意一次。
实施例二,显示组件子集的每一次显示时刻与对应的发光组件子集的每一次发光时刻均相匹配。也就是,多个发光组件子集按照预设次序依次被点亮时,与该刚被点亮的发光组件子集对应的显示组件子集也恰好刚进行显示。如此,便可保证,不论循环多少次(例如在显示视频流时,每显示一帧图像,发光组件子集与显示组件子集便分别进行一次发光和显示,如此形成一次循环),每个发光组件子集每一次刚被点亮时,与其对应的显示组件一定恰好刚进行对应次的显示。本实施例相比现有技术,彻底避免了显示组件子集的显示时刻与发光组件子集的发光时刻不匹配的问题发生。
实施例三,图9为本申请的另一实施例中的显示设备的一种显示状态的波形图,图中1代表显示组件子集动作波形,2代表发光组件子集动作波形。如图9所示,对应的显示组件子集的第一次或任意一次的进行显示的时长(即保持显示状态的时长)与发光组件子集的第一次或任意一次进行发光的时长(即保持发光状态的时长)相匹配。也即,相比现有技术,本实施例的电子设备在显示画面的过程中至少有一次显示组件子集保持显示状态的时间与发光组件子集保持发光状态的时间相匹配,而其他次显示时两个时间并不一定相匹配。例如,仍以实施例一中的场景为例,导光板第一次(或任意一次)被点亮后保持发光状态的时长与对应的像素组第一次(或任意一次)保持显示的时长相匹配。
实施例四,对应的显示组件子集的第一次或任意一次的进行显示的时刻以及时长与发光组件子集的第一次或任意一次进行发光的时刻以及时长均相匹配。也就是,相比现有技术,本实施例的电子设备在显示画面的过程中至少有一次显示组件子集开始进行显示的时刻与保持显示的时长均与发光组件子集对应次进行发光的时刻与保持发光的时长相匹配,而其 他次二者可不相匹配。例如仍以实施例一中所示场景为例,由实施例一可知,导光板第一次(或任意一次)发光的时刻与像素组第一次(或任一次)显示的时刻相匹配。但是为了进一步提高显示效果,使得导光板在本次保持发光状态的时间里对应的像素组不仅均处于显示状态,而且保持显示状态的时间与导光板保持发光状态的时间相等,就需要如本实施例中一样,需同时限制导光板在第一次(或任一次)保持发光状态的时长与像素组在第一次(或任一次)保持显示状态的时长相匹配,从而实现上述技术效果,避免像素组已结束显示状态,而导光板却仍处于发光状态,或相反地,导光板已结束发光状态,但像素组却仍处于显示状态的现象发生。
实施例五,对应的显示组件子集的每一次保持显示状态的时长与发光组件子集的每一次保持发光状态的时长相匹配。也就是每个发光组件子集保持发光状态的时间均与对应的显示组件子集保持显示状态的时间相等。例如,同样以实施例一中的例子为例,即为每块导光板的单次发光时长均与对应的像素组的对应次显示时长相等。也即,本实施例相比现有技术,彻底避免了显示组件子集每次保持显示的时间与发光组件子集每次保持发光的时间不匹配的问题发生。
实施例六,对应的发光组件子集的发光频率与显示组件子集的显示频率相匹配。以显示组件子集为一组像素为例,该像素组在进行显示时是按照一定频率进行的,每一次显示均显示一帧图像,其通过按照显示频率能够依次进行多次显示从而实现后多帧图像的连续显示。也可认为是像素组的像素每刷新一次,便开始显示下一帧图像。其中,需注意的是,由于每个显示组件子集均具有多个像素,每个像素的显示频率在理想状态下是相等的,然而在实际应用中却很难达到,因此,本实施中在此提到的显示频率为平均显示频率。进一步地,以发光组件子集为导光板(或一组LED灯、一根或多根灯管等)为例,其也并非持续性发光,而是配合像素的显示频率同样按照一定频率间歇性发光。故,若要使得对应的发光组件子集和显示组件子集能够相匹配,避免出现现有技术中在导光板被点亮时,对应的像素组并未进行显示,而导致的显示滞后现象的发生;或避免出现现有技术中在导光板结束发光时,对应的像素组却开始进入显示状态,如开始显示下一帧图像,而导致的黑屏现象的发生,也就是避免出现图11中 分别对应a、b、c三点的显示组件子集与发光组件子集间显示与发光不匹配的现象发生,就需要使发光组件子集的发光频率和对应的显示组件子集的显示频率相匹配,即,发光组件子集不仅发光时间与对应的显示组件子集的显示时间相匹配,且发光组件子集停止发光的时间与对应的显示组件子集停止显示的时间也相匹配,以保证在发光组件子集进行发光时,对应的显示组件子集进行显示,而发光组件子集停止发光时,对应的显示组件子集停止显示。
实施例七,图10为本申请的另一实施例中的显示设备的一种显示状态的波形图,图中虚线箭头所指的波形代表发光组件子集的动作波形,位于发光组件子集的动作波形上方的波形代表显示组件子集的动作波形。如图10所示,对应的发光组件子集的发光时刻与显示组件子集的显示时刻匹配,同时发光组件子集的单次发光时长与对应的显示组件子集的单次显示时长相匹配。
具体地,为了保证在各发光组件子集进入发光状态时,与各进入发光状态的发光组件子集对应的各显示组件子集同时恰好进入显示状态(如正在显示第一帧图像或完成刷新并开始显示第二帧图像),即,各显示组件子集每次开始显示的时刻与对应的发光组件子集每次开始发光的时刻均相匹配,就需要使各发光组件子集的波形曲线和对应的显示组件子集的波形曲线的时间起点相同,且发光组件子集的每个发光周期的时间起点需要与对应的显示组件子集的整数倍个显示周期的时间起点相同。也就是,发光组件子集的发光频率与对应的显示组件子集的显示频率可相等,也可为倍数(需为整数倍)关系。而若要同时避免在发光组件子集结束发光时,对应的显示组件子集却开始显示下一帧图像而导致的黑屏现象的发生,就需要在满足上述关系的同时使发光组件子集的单次发光时长(保持发光状态的时长)与对应的显示组件子集的单次显示时长(保持显示状态的时间)相匹配。使得发光组件子集的每个发光周期的波形与对应的显示组件子集的每整数个显示周期的波形一一对应,保证各显示组件子集在每一次刷新图像后均能够充分显示,且显示周期与对应发光组件子集的发光周期匹配,彻底避免了显示的画面出现内容不匹配现象或黑屏现象。也即,图10所示的电子设备完全克服了图11所示的电子设备包含的显示与发光不匹配 的技术问题。
另外,需指出的是,本申请上述各实施例中指出的同一显示组件子集内的显示组件同时显示画面,以及对应的发光组件子集中的发光组件同时发光,也即二者相匹配均是从宏观角度来看的。例如一块导光板对应多行像素,二者动作相匹配是从宏观角度上而言的。而若以微观角度来看,本申请中相对应的显示组件子集与发光组件子集相匹配则为显示组件子集中第一个进行显示的显示组件与发光组件子集中第一个发光的显示组件相匹配。也即,继上述举例内容,导光板与第一行第一个像素相匹配。
进一步地,本实施例中的显示方法还包括利用检测装置和处理装置使电子设备进行显示调节时能够自适应调整的步骤,也就是使电子设备能够对自身的显示模式和发光模式等进行自适应调整,以使得其显示效果更佳。而为了适配具有不同设置类型的发光组件及显示组件的电子设备,本实施例中的检测方式不唯一,具体如下:
第一种检测方式:
检测发光组件子集的设置形式,如检测多个发光组件子集是纵向排列设置还是横向排列设置,并根据检测结果确定与各发光组件子集对应的显示组件子集的组成形式,如确定哪些显示组件形成与各发光组件子集对应的显示组件子集。
本实施例中的检测方式可应用于在发光组件子集的设置位置以及发光顺序固定时,来根据发光组件子集的发光形式确定出与各发光组件子集对应的显示组件子集,以及显示组件子集的显示顺序。而该发光形式的信息可从预置的存储装置中读取设备的型号或参数,当然,具体的获取方式不唯一,也可为通过人工输入等通道获取。具体地,当发光组件集合为多排(多列)灯管或导光板(也可为一片LED灯),显示组件集合为一片像素时,检测装置检测到每排灯管或导光板均形成一发光组件子集,且其发光模式为由上至下时,处理装置则根据检测结果来确定出如何将该多个像素进行划分,以形成多个用于和发光组件子集相对应的显示组件子集。例如包括四块由上至下依次设置的导光板,分别形成四个发光组件子集,处理装置则将多个像素分为四组,以分别形成四个显示组件子集,该四个显示组件子集同样由上至下依次排列设置,每一个显示组件子集均与唯一一 个发光组件子集相对应。当然,倘若显示组件较多时,还可令相邻两个或多个显示组件子集均与一发光组件子集相对应。
第二种检测方式:
检测显示组件子集的显示策略,例如,显示组件子集以何种方式进行显示,多个显示组件子集是由上至下依次显示还是从左到右依次显示,并根据检测到的显示策略确定与各显示组件子集对应的发光组件子集的组成形式。
本实施例中的检测方式可应用于在显示组件子集的设置位置以及发光顺序固定时,来根据显示组件子集的显示形式而确定出与各显示组件子集对应的发光组件子集,以及发光组件子集的发光顺序。而该显示形式的信息可从预置的存储装置中读取设备的型号或参数,当然,具体的获取方式不唯一,也可为通过人工输入等通道获取。例如以发光组件集合为多排LED灯为例,当检测装置检测到多个显示组件子集是由上到下依次显示时,处理装置则根据多个显示组件子集的设置位置以及显示顺序而对多排LED灯进行划分,使每一排或相邻的多排LED灯形成一发光组件子集,以此确定出分别与各显示组件子集对应的各发光组件子集以及该多个发光组件子集的发光顺序。
以上为本发明的最优实施例,需要说明的,该最优的实施例仅用于理解本发明,并不用于限制本发明的保护范围。并且,最优实施例中的特征,在无特别注明的情况下,均同时适用于方法实施例和装置实施例,在相同或不同实施例中出现的技术特征在不相互冲突的情况下可以组合使用。
需要说明的是,上述对各元件的定义并不仅限于实施方式中提到的各种具体结构或形状,本领域的普通技术人员可对其进行简单地熟知地替换,以上所述的具体实施例,对本发明的目的、技术方案和有益效果进行了进一步详细说明,所应理解的是,以上所述仅为本发明的具体实施例而已,并不用于限制本发明,凡在本发明的精神和原则之内,所做的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
