具体实施方式
为了使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开实施方式作进一步地详细描述。
图1是本公开实施例提供的一种显示装置的结构示意图。如图1所示,该显示装置包括:处理器01和背光源02。
其中,背光源02具有多个背光分区A1(图中共示出2个),即可以预先将背光源02划分为多个分区。且,每个背光分区A1可以包括多个发光元件L1。
可选的,背光源02可以为mini LED背光源,相应的,发光元件L1即可以为mini LED,mini LED也可以称为次毫米级发光二极管,尺寸一般介于50微米(μm)至500μm之间,即大于等于50μm小于等于500μm。继续参考图1,处理器01可以与背光源02连接,且处理器01可以用于执行以下操作:
(1)响应于调节启动指令,显示触控控件。
其中,该触控控件可以包括:第一亮度调节控件。即,首先,当用户想要调节背光源02的亮度时,其可以通过如触控或语音控制等操作触发显示装置进入背光源亮度调节状态。此时,处理器01可以接收到调节启动指令,并可以进一步显示如图1所示的第一亮度调节控件J1,以供用户触控。
例如,显示装置上可以设置有启动调节亮度的实体按键或是显示装置的显示屏03上可以显示有启动调节亮度的触摸按键,用户可以通过点击上述按键以触发显示装置进入背光源亮度调节状态,即使得处理器01接收调节启动指令。本公开实施例对触发调节启动指令的方式不做限定。以及本公开实施例记载的点击操作可以包括:单击、双击或是长按等操作,下述实施例不再赘述。
(2)根据接收到的针对第一亮度调节控件的第一触控操作,确定第一亮度调节量。
然后,用户可以针对显示的第一亮度调节控件J1执行触控操作,该触控操作也称为第一触控操作。此时,处理器01即可以接收到该第一触控操作,并可以基于该第一触控操作,确定针对亮度进行调节的第一亮度调节量。
(3)确定多个背光分区中待调节的目标分区。
以及,处理器01还可以预先从背光源02具有的多个背光分区A1中确定出需要调节亮度的目标分区。如,处理器01中可以预先存储有默认的待调节背光分区A1,在此基础上,处理器01可以将该默认的背光分区A1确定为目标分区。
(4)根据第一亮度调节量调节该目标分区中多个发光元件的亮度。
最后,处理器01即可以根据预先确定的第一调节量,调节预先确定的目标分区中多个发光元件L1的亮度,以实现针对多个背光分区A1中任一背光分区的亮度调节。
综上所述,本公开实施例提供了一种显示装置,该显示装置包括处理器和 具有多个背光分区的背光源。其中,处理器可以基于调节启动指令显示第一亮度调节控件,且可以根据接收到的针对该第一亮度调节控件的触控操作,调节多个背光分区中目标分区包括的多个发光元件的亮度。如此,相对于目前仅能针对背光源的整体亮度进行调节,本公开实施例提供的显示装置中,针对背光源的亮度进行调节的灵活性更好。
可选的,继续参考图1可以看出,显示装置一般还可以包括显示屏03,处理器01还可以与显示屏03连接。在此基础上,处理器01可以用于响应于接收到的调节启动指令,在显示屏03上显示触控控件,如显示图1所示的第一亮度调节控件J1。下述实施例均以在显示屏03上显示触控控件为例进行说明。此外,显示屏03可以为LCD显示屏,也可以称为LCD面板。
当然,在一些实施例中,显示装置还可以外接控制设备(如,移动终端),处理器可以与控制设备连接,并用于响应于接收到的调节启动指令,在控制设备的显示屏上显示触控控件。本公开实施例对触控控件的显示位置不做限定。
可选的,图2是本公开实施例提供的一种背光源的结构示意图。参考图2可以看出,本公开实施例记载的背光源02可以包括拼接的多个灯板021,每个灯板021可以具有至少两个背光分区A1。即,图1中背光源02具有的多个背光分区A1其实可以对应至多个灯板021中,每个灯板021可以包括多个发光元件L1。需要说明的是,在背光源02为mini LED背光源的基础上,灯板021也可以称为mini LED灯板。以及,拼接多个灯板021形成的背光源02通常应用于大尺寸LCD面板中,如,65寸LCD面板中。
此外,该多个灯板021可以阵列排布,即背光源02可以包括多行多列个灯板021。以及,每个灯板021包括的多个发光元件L1也可以阵列排布,即每个灯板021可以包括多行多列个发光元件L1。发光元件行方向与灯板行方向可以相同,发光元件列方向与灯板列方向也可以相同。当然,在一些其他实施例中,该多个灯板021和/或多个发光元件L1也可以仅按行排布,或是仅按列排布,或是不规则排布,本公开实施例对其排布方式均不作限定。
例如,图2示出的背光源02共包括8个灯板021,图2中分别标识为灯板021-1至灯板021-8。且,图2示出的8个灯板021按照2行4列的方式排布。在图2基础上,图3示出了灯板021-1的结构示意图。参考图3可以看出,该灯 板021-1包括56行48列个发光元件L1。
可选的,在多个灯板021拼接的基础上,相邻灯板021之间自然会形成拼缝,即拼接形成的缝隙,也可以称为间隙。即,参考图2,本公开实施例记载的多个灯板021中,每相邻两个灯板021之间均可以具有拼缝f1。
可选的,再结合图4所示的灯板021-1和灯板021-2的示意图可知,本公开实施例记载的每个灯板021可以具有第一背光分区A1-1和第二背光分区A1-2共两个背光分区A1。第一背光分区A1-1可以邻近拼缝f1,且位于拼缝f1与第二背光分区A1-2之间。即,第一背光分区A1-1相对于第二背光分区A1-2更靠近拼缝f1。
可选的,再结合图5所示的灯板021-1的结构示意图可知,本公开实施例记载的每个灯板021还可以具有除第一背光分区A1-1和第二背光分区A1-2的第三背光分区A1-3和第四背光分区A1-4。即,本公开实施例记载的每个灯板021可以具有四个背光分区A1。
其中,第一背光分区A1-1、第二背光分区A1-2和第三背光分区A1-3可以沿第一方向X依次排布,且第二背光分区A1-2和第四背光分区A1-4可以沿第二方向Y依次排布。可选的,在多个灯板021阵列排布的基础上,第一方向X可以认为是灯板行方向,第二方向Y可以认为是灯板列方向。
可选的,从图5还可以看出,第四背光分区A1-4与第一背光分区A1-1也可以认为是沿第二方向Y依次排布,第四背光分区A1-4与第三背光分区A1-3也可以认为是沿第二方向Y依次排布。即,对于图4所示结构而言,第一背光分区A1-1和第三背光分区A1-3可以认为是分别位于第二背光分区A1-2的左侧和右侧,与第二背光分区A1-2邻接(即,相邻且接触)。第四背光分区A1-4可以认为是位于由第二背光分区A1-2、第一背光分区A1-1和第三背光分区A1-3组成的整个分区的下侧,且与第二背光分区A1-2、第一背光分区A1-1和第三背光分区A1-3均邻接。第二背光分区A1-2的面积最大。当然,在一些实施例中,第四背光分区A1-4可以仅与第二背光分区A1-2沿第二方向Y依次排布,第一背光分区A1-1,由第四背光分区A1-4和第二背光分区A1-2组成的整个分区,以及第三背光分区A1-3沿第一方向X排布。
再结合图3,可以将位于第1行至第54行,且位于第1列和第2列的各个发光元件L1划分至背光分区A1-1;将位于第1行至第54行,且位于第47列和 第48列的各个发光元件L1划分至背光分区A1-3;将位于第55行和第56行,且位于第1列至第48列的各个发光元件L1划分至背光分区A1-4;以及将剩余的各个发光元件L1(即,位于第1行至第54行,且位于第3列和第46列的各个发光元件L1)划分至背光分区A1-4。该划分方式仅是示意说明,不做限定。
在图5基础上,图6示出了图2所示背光源02中,灯板021-1、灯板021-2、灯板021-5和灯板021-6的结构示意图。参考图6可以看出,在第一方向X上,每相邻两个灯板021(如,灯板021-1和灯板021-2)中,一个灯板的第一背光分区A1-1与另一个灯板的第三背光分区A1-3可以相邻。在第二方向Y上,每相邻两个灯板021(如,灯板021-1和灯板021-5)中,一个灯板的第四背光分区A1-4与另一个灯板的第四背光分区A1-4可以相邻。即,每个灯板021具有的四个背光分区A1中,第四背光分区A1-4与沿第一方向X延伸的拼缝f1邻接,第一背光分区A1-1或第三背光分区A1-3与沿第二方向Y延伸的拼缝f1邻接。
可选的,为独立驱动每个灯板021发光,每个灯板021一侧均可以设置有至少一个驱动集成电路(integrated circuit,IC),该驱动IC分别与主机端的控制电路和灯板021上的发光元件L1连接,以在控制电路驱动下,向发光元件L1传输驱动电流,从而驱动发光元件L1发光,即驱动灯板021发光。下述实施例将控制电路称为第一驱动电路,驱动IC称为第二驱动电路,第一驱动电路和第二驱动电路可以统称为背光源驱动电路。
可选的,每个背光分区A1其实还可以具有多个子分区,每个子分区可以包括至少一个发光元件L1,驱动IC可以向各个子分区的发光元件L1单独提供驱动电流,以实现局部调光(local dimming)的目的。换言之,处理器01还可以用于分别独立控制各个子分区中发光元件的亮度。
如,在图2和图5基础上,以灯板021-1为例,图7还示出一种单个灯板021-1的网表图。参考图7可以看出,每4个mini LED(如,1-1L1、2-1L1、3-1L1和4-1L1)可以为一组,位于一个子分区,图7所示灯板021-1共包括672组。再对应至图5可知,第一背光分区A1-1对应1-1L1至3-7L1所在区域;第四背光分区A1-4对应4-7L1至4-7L24所在区域;第三背光分区A1-3对应1-1L24至3-7L24所在区域;第二背光分区A1-2对应其余区域。
需要说明的是,图2至图7均仅是示意性说明。在一些其他实施例中,背光源02也可以包括更多或更少数量的灯板021。每个灯板021也可以具有更多 或更少数量的背光分区A1。每个灯板021上也可以包括更多或更少数量的发光元件L1。以及,单个灯板网表也可以为其他形式。本公开实施例对上述参数均不作限定。
受组装灯板021以形成背光源02的过程中,公差累计和/或定位精度较差的影响,相邻两个灯板021的板间距离实测值往往会偏离理想设计值,从而造成靠近拼缝f1位置的发光元件L1的发光亮度出现异常,进而导致LCD面板的显示效果不佳。板间距离是指相邻两个灯板021中,一个灯板021上靠近拼缝f1处的发光元件L1与另一个灯板021上靠近拼缝f1处的发光元件之间的距离。
以图2中灯板021-1和灯板021-2为例,结合图3和图6,在公差累计和/或定位精度较差的影响下,灯板021-1的第三背光分区A1-3中发光元件L1与灯板021-2的第一背光分区A1-1中发光元件L1的间距会出现偏差,该偏差会进一步造成灯板021-1的第三背光分区A1-3中发光元件L1与灯板021-2的第一背光分区A1-1中发光元件L1的发光亮度出现异常,进而导致LCD面板的显示效果出现异常。如,导致灯板021-1的第三背光分区A1-3与灯板021-2的第一背光分区A1-1之间出现明显的竖向暗线(即,亮度低)或是竖向亮线(即,亮度高)。需要说明的是,上述显示异常问题在低混光距离(optical distance,OD)条件下尤为明显,其中,混光距离OD是指:背光源02包括的灯板021与显示装置包括的扩散板之间的间距,一般为垂直距离。低混光距离是指大于0且小于等于6毫米(mm)的混光距离。
例如,经测试,在65寸LCD面板处于混光距离为5mm的测试条件下,用于标定相邻灯板021之间距离的定位柱的直径公差一般在±0.1mm左右,每相邻两个定位柱之间的距离公差也在±0.1mm左右。在灯板行方向X上,若每相邻两个灯板021之间的板间距离能够控制在6.8mm、6.9mm或是7mm,背光源02各个背光分区A1中发光元件L1的发光亮度正常,LCD面板的显示效果正常。而若每相邻两个灯板021之间的板间距离位于6.6mm至6.7mm之间,LCD面板即出现亮线异常;以及,若每相邻两个灯板021之间的板间距离为7.1mm,LCD面板即出现暗线异常。由该测试结果也可以看出,间距稍许变动则会导致LCD面板出现显示异常问题。
以及,经测试,上述实施例记载的各个驱动IC实际工作时输出的驱动电路会存在差异,差异一般在±3%左右。该差异同上述拼缝间距一样,也会导致各 个灯板之间存在亮度差异,人眼视觉上LCD面板的显示效果存在色差。
而在本公开实施例中,通过对各个背光分区A1中发光元件L1的亮度进行独立灵活调整,可以解决上述拼缝间距或电流差异造成的显示效果较差的问题,确保LCD面板的显示效果较好。如,确保LCD面板显示画面的均一性较好。
以及,如上述实施例记载,结合图8,显示装置一般还可以包括:位于背光源02远离衬底01一侧的扩散板B1,该扩散板B1可以用于扩散背光源02发出的光线。并且,背光源02包括的灯板021与扩散板B1之间的第一间距d1可以大于0且小于等于6mm,即位于0-6mm之间。第一间距d1即为上述实施例记载的混光距离OD。
在此基础上,每相邻两个灯板021之间的第二间距d2与第一间距d1的比值(即,d2/d1)可以大于等于1.2且小于等于8,即位于1.2-8之间。其中,第二间距d2为具有拼缝的每相邻两个灯板021中,一个灯板021上靠近拼缝f1处的发光元件L1与另一个灯板021上靠近拼缝f1处的发光元件L1之间的距离。即,第二间距d2为上述实施例记载的每相邻两个灯板021的板间距离。
换言之,混光距离OD可以位于0-6mm之间,板间距离可以位于4mm-8mm之间。如,可以设置混光距离OD等于5mm,且设置板间距离等于7mm。在上述间距设置基础上,经测试验证,也可以一定程度上改善背光源02的发光亮度,确保显示装置的显示效果较好。
当然,在一些实施例中,也可以在组装灯板021以形成背光源02时,采用机器视觉定位检测技术实现对各个灯板021位置的精确定位,确保拼缝f1处相邻灯板021之间的板间距离能够严格按照设计值进行控制,从而确保LCD面板的显示效果较好。但是,机器视觉定位检测技术需投入昂贵的定位设备,成本较大;且定位过程较为耗时,效率较低,且因定位时需要用背胶粘贴灯板,后期可维修性较差;且无法解决电流差异造成的色差问题,应用场景较为局限。
在上述图2至图7基础上,继续参考图9可以看出,本公开实施例记载的第一亮度调节控件J1可以包括:与多个背光分区A1一一对应的多个亮度调节子控件J11。如,对于每个灯板021而言,其具有的4个背光分区A1-1至A1-4可以均分别对应一个亮度调节子控件J11。以及,第一触控操作可以为针对多个亮度调节子控件J11中目标子控件的点击操作(如,单击、双击或长按)。当然,在一些其他实施例中,第一触控操作还可以为点击亮度调节子控件J11,且输入 具体亮度的操作,本公开实施例对第一触控操作的方式不做限定。
并且,参考图9还可以看出,显示屏03可以具有与多个背光分区A1一一对应的多个显示区域B1,每个背光分区A1对应的亮度调节子控件J11可以位于背光分区A1对应的显示区域B1内。以及,每个显示区域B1可以由对应的一个背光分区A1提供背光。对于每个显示区域B1而言,由对应的一个背光分区A1提供背光可以是指:仅由其唯一对应的背光分区A1提供背光,或是由该唯一对应的背光分区A1和相邻显示区域B1对应背光分区A1所提供的背光扩散光线共同提供的背光。如此,用户可以可靠观察到亮度异常现象出现在哪个背光分区A1,并针对性的快速可靠点击该背光分区A1所在显示区域B1上显示的亮度调节子控件J11,以实现对该背光分区A1中发光元件L1亮度的灵活调节,改善了用户体验。当然,在一些其他实施例中,也可以直接在显示屏03上以表格的形式显示各个灯板021的背光分区A1与对应的亮度调节子控件J11。此外,参考图9还可以看出,在显示上述内容基础上,处理器01还可以在显示屏03上显示各个背光分区A1当前亮度(如,127),以便用户查看。
在图9所示结构基础上,本公开实施例记载的处理器01,可以用于:根据接收到的针对目标子控件的点击操作,确定第一亮度调节量。
可选的,处理器01可以用于获取针对目标子控件的点击操作的次数,并根据该次数灵活确定第一亮度调节量。
例如,假设点击一次目标子控件亮度调节量加1,则若处理器01确定的次数为4,则可以确定第一调节量为4。假设点击一次目标子控件亮度调节量加2,则若处理器01确定的次数为4,则可以确定第一调节量为8。同理,假设点击一次目标子控件亮度调节量减1,则若处理器01确定的次数为4,则可以确定第一调节量为-4。假设点击一次目标子控件亮度调节量减2,则若处理器01确定的次数为2,则可以确定第一调节量为-4。
以及,本公开实施例记载的处理器01,可以用于:根据接收到的针对目标子控件的点击操作,确定待调节的目标分区。其中,确定的目标分区可以为多个背光分区中,目标子控件对应的背光分区。即,在用户点击了多个亮度调节子控件J11中的某个亮度调节子控件J11(即,目标子控件)后,处理器01可以获取到该亮度调节子控件J11所对应的背光分区A1,并可以将该背光分区A1确定为待调节亮度的目标分区。
例如,结合图9,若用户点击的亮度调节子控件J11为灯板021-1中第三背光分区A1-3对应的亮度调节子控件J11,则处理器01可以将该灯板1具有的背光分区A1-3确定为目标分区。
可选的,继续参考图9可以看出,每个亮度调节子控件J11可以包括:第一亮度增子控件J11+和第一亮度减子控件J11-。在此基础上,处理器01可以用于:
根据接收到的针对第一亮度增子控件的点击操作,确定第一亮度增量;以及,根据接收到的针对第一亮度减子控件的点击操作,确定第一亮度减量。
其中,第一亮度增量可以大于0。第一亮度减量可以小于0。如,假设点击一次第一亮度增子控件J11+,亮度增量+1,则若处理器01确定针对第一亮度增子控件J11+的点击操作的次数为3,则可以确定第一亮度增量为3。假设点击一次第一亮度减子控件J1-,亮度增量-1,则若处理器01确定针对第一亮度减子控件J1-的点击操作的次数为1,则可以确定第一亮度减量为-1。
之后,处理器01可以用于累加第一亮度增量和第一亮度减量,得到第一亮度调节量。如,假设第一亮度增量为3,第一亮度减量为-1,则处理器01可以计算得到第一亮度调节量为:3+(-1)=2。假设第一亮度增量为3,第一亮度减量为-5,则处理器01可以计算得到第一亮度调节量为:3+(-5)=-2。由此也可以确定,第一亮度调节量可以大于0,也可以小于0。当然,若仅点击第一亮度增子控件J1+,则第一亮度调节量大于0;若仅点击第一亮度减子控件J1-,则第一亮度调节量小于0。
当然,在一些其他实施例中,亮度调节子控件J11可以不存在第一亮度增子控件J11+和第一亮度减子控件J11-的区分。在此基础上,针对亮度调节子控件J11的一次点击操作可以将第一亮度调节量+1或-1。第一亮度调节量可以对应一个第一调节量阈值和第二调节量阈值,第一调节量阈值大于第二调节量阈值。在累加多次1之后,第一亮度调节量若达到第一调节量阈值,则处理器01将第一亮度调节量清零,并开始-1。在累减多次1之后,第一亮度调节量若达到第二调节量阈值,则处理器01将第一亮度调节量清零,并开始+1。以此类推。
结合上述实施例记载可知,在确定出第一亮度调节量和目标分区之后,处理器01即可以用于:根据第一亮度调节量调节目标分区中多个发光元件的亮度。
例如,目标分区中多个发光元件L1的亮度可以对应一个亮度值,该亮度值可以为多个发光元件L1的亮度均值,如此也可以认为是调节目标分区的发光亮 度。在此基础上,处理器01可以预先获取到目标分区还未被调节的初始亮度,然后可以在初始亮度基础上累加第一亮度调节量,使得目标分区的亮度达到目标亮度,实现对目标分区中多个发光元件L1的亮度的调节。
如,若第一亮度调节量大于0,则可以认为是增大目标分区中多个发光元件L1的亮度。若第一亮度调节量小于0,则可以认为是减小目标分区中多个发光元件L1的亮度。结合上述实施例记载可知,仅针对第一亮度增子控件J1+和第一亮度减子控件J1-中第一亮度增子控件J1+进行点击,则可以实现提高亮度的目的;仅针对第一亮度增子控件J1+和第一亮度减子控件J1-中第一亮度减子控件J1-进行点击,则可以实现降低亮度的目的。
可选的,目标分区中多个发光元件L1的亮度也可以对应多个亮度值。在此基础上,可以设置每个背光分区A1对应的亮度调节子控件J1包括与多个亮度值一一对应的子控件,从而实现对各个亮度值的灵活调节。
可选的,继续参考图9可以看出,本公开实施例记载的触控控件还可以包括:第二亮度调节控件Num。即,结合图9,处理器01,还可以用于:响应于调节启动指令,在显示屏03上显示第二亮度调节控件Num。以及,用于根据接收到的针对第二亮度调节控件Num的第二触控操作,确定第二亮度调节量。
可选的,继续参考图9可以看出,同第一亮度调节控件J1,该第二亮度调节控件Num可以包括:第二亮度增子控件Num+和第二亮度减子控件Num-。以及,同第一触控操作,该第二触控操作也可以为针对第二亮度调节控件Num的点击操作。且在一些其他实施例中,第二触控操作还可以为点击第二亮度调节控件Num,且输入具体亮度的操作,本公开实施例对第二触控操作也不做限定。
在此基础上,本公开实施例记载的处理器01,可以用于:根据接收到的针对第二亮度增子控件Num+和的点击操作,确定第二亮度增量;以及,根据接收到的针对第二亮度减子控件Num-的点击操作,确定第二亮度减量。
其中,第二亮度增量可以大于0。第二亮度减量可以小于0。如,假设点击一次第二亮度增子控件Num+,亮度增量+1,则若处理器01确定针对第二亮度增子控件Num+的点击操作的次数为5,则可以确定第二亮度增量为5。假设点击一次第二亮度增子控件Num+,亮度增量-1,则若处理器01确定针对第二亮度增子控件Num+的点击操作的次数为2,则可以确定第二亮度减量为-2。具体实现方式可以参考上述确定第一亮度增量和第一亮度减量的方式。
之后,处理器01也可以用于:累加第二亮度增量和第二亮度减量,得到第二亮度调节量。如,假设第二亮度增量为5,第二亮度减量为-2,则处理器01可以计算得到第二亮度调节量为:5+(-2)=3。假设第二亮度增量为2,第一亮度减量为-4,则处理器01可以计算得到第二亮度调节量为:2+(-4)=-2。由此也可以确定,第二亮度调节量可以大于0,也可以小于0。当然,若仅点击第二亮度增子控件Num+,则第二亮度调节量大于0;若仅点击第二亮度减子控件Num-,则第二亮度调节量小于0。
当然,在一些其他实施例中,同亮度调节子控件J1,第二亮度调节控件Num也可以不存在第二亮度增子控件Num+和第二亮度减子控件Num-的区分,针对第二亮度调节控件Num的一次点击操作可以将第二亮度调节量+1。以及,第二亮度调节量也可以对应一个第一调节量阈值和第二调节量阈值,第一调节量阈值大于第二调节量阈值。在累加多次1之后,第二亮度调节量若达到第一调节量阈值,则将第二亮度调节量清零,并开始-1。在累减多次1之后,第二亮度调节量若达到第二调节量阈值,则将第二亮度调节量清零,并开始+1。以此类推。
在确定出第二亮度调节量之后,处理器01即可以进一步用于:根据第二亮度调节量调节每个背光分区A1中多个发光元件L1的亮度。
如,依然以一个背光分区A1对应一个亮度值为例,处理器01也可以预先获取到每个背光分区A1还未被调节的初始亮度,然后可以在该初始亮度基础上,将每个背光分区A1的初始亮度均累加第二亮度调节量,从而实现对每个背光分区A1亮度的同时且统一调节。
如,若第二亮度调节量大于0,则可以认为是同时增大每个背光分区A1中发光元件L1的亮度。若第二亮度调节量小于0,则可以认为是同时减小每个背光分区A1中多个发光元件L1的亮度。结合上述实施例记载可知,仅针对第二亮度增子控件Num+和第二亮度减子控件Num-中第二亮度增子控件Num+点击,则可以实现提高亮度的目的;仅针对第二亮度增子控件Num+和第二亮度减子控件Num-中第二亮度减子控件Num-点击,则可以实现降低亮度的目的。
基于上述实施例记载可知,在本公开实施例中,第二亮度调节控件Num的设置其实是用于供处理器01对背光源02整体亮度进行统一且同时调节。第一亮度调节控件J1的设置其实是用于供处理器01对背光源02中各个背光分区A1包括的多个发光元件L1的亮度进行独立调节。
可选的,继续参考图9可以看出,本公开实施例记载的触控控件还可以包括:第二亮度调节控件Num。即,结合图9,处理器01,还可以用于:响应于调节启动指令,在显示屏03上显示亮度重置控件Reset。以及,用于根据接收到的针对亮度重置控件Reset的第三触控操作,将每个背光分区A1中多个发光元件L1的亮度均重置为基准亮度。
示例的,同第一触控操作,第三触控操作也可以为针对亮度重置控件Reset的点击操作。当用户想要将每个背光分区A1中发光元件L1的亮度均重置为基准亮度,则可以点击该亮度重置控件Reset。此时,处理器01即可以接收到针对亮度重置控件Reset的第三触控操作,并且可以根据该第三触控操作,快速且可靠的将背光源01具有的各个背光分区A1中,发光元件L1的亮度均由其初始亮度重置为相同的基准亮度。在此基础上,基准亮度可以为预先存储于处理器01中的固定值。如,假设基准亮度为128,各个背光分区A1中发光元件L1的当前亮度如图9中显示屏上所显示。则,当用户点击亮度重置控件Reset后,处理器01即可以将每个背光分区A1中发光元件L1的当前亮度均重置为128。
当然,在一些其他实施例中,第三触控操作还可以为点击亮度重置控件Reset,且输入基准亮度的操作。在此基础上,处理器01中无需预先存储基准亮度,而是接收用户输入的基准亮度即可。本公开实施例对第三触控操作的方式也不做限定。
可选的,继续参考图9还可以看出,本公开实施例记载的触控控件还可以包括:画面切换控件Color。即,结合图9,处理器01,还可以用于:响应于调节启动指令,在显示屏03上显示画面切换控件Color。以及,用于根据接收到的针对画面切换控件Color的第四触控操作,控制显示屏03切换显示不同颜色的画面。
可选的,同第一触控操作,第四触控操作也可以为针对画面切换控件Color的点击操作。当用户想要观看不同颜色的画面时,可以点击该画面切换控件Color。此时,处理器01即可以接收到针对画面切换控件Color的第四触控操作,且可以根据该第四触控操作,灵活控制显示屏03切换显示不同颜色的画面。其中,点击一次可以切换一下,即从一种颜色的画面切换至另一种颜色的画面。
可选的,该不同颜色的画面可以为预先存储于处理器01中的固定画面。如,一般包括图10所示的纯白画面、纯红画面、纯绿画面和纯蓝画面四种颜色的画 面。当然,也可以包括50%的灰色画面,显示屏默认显示白色画面。以及,切换顺序也可以预先存储于处理器01中。
如,假设显示屏03当前显示画面为纯白画面,切换顺序为纯白画面至纯红画面至纯绿画面至纯蓝画面,则当用户点击一次画面切换控件Color后,处理器01可以控制显示屏03从纯白画面切换至纯红画面,再点击一次画面切换控件Color后,处理器01可以控制显示屏03从纯红画面切换至纯绿画面,以此类推。切换显示不同颜色画面的目的是:供用户观看调节亮度后,显示屏03在显示不同颜色画面时的显示效果是否均较好。若在一次调节后,显示屏03显示纯绿画面的显示效果依然不佳,则可以针对该纯绿画面,对亮度进行二次微调。
可选的,继续参考图9可以看出,画面切换控件Color可以包括:第一切换子控件Color+和第二切换子控件Color-。在此基础上,本公开实施例记载的处理器01,可以用于:
根据接收到的针对第一切换子控件Color+的第四触控操作,控制显示屏03按照第一切换顺序,切换显示不同颜色的画面。根据接收到的针对第二切换子控件Color-的第四触控操作,控制显示屏03按照第二切换顺序,切换显示不同颜色的画面。其中,第一切换顺序与第二切换顺序的颜色切换方向相反。如此,可以提高画面切换灵活性。
以不同颜色的画面包括图10所示的纯白画面、纯红画面、纯绿画面和纯蓝画面为例,假设第一切换顺序为图10所示的纯白画面至纯红画面至纯绿画面至纯蓝画面依次切换,则第二切换顺序即可以为图10所示的纯蓝画面至纯绿画面至纯红画面至纯白画面依次切换。若显示屏03当前显示的画面为纯绿画面,且用户点击了一次第一切换子控件Color+,则处理器01可以控制显示屏03从该纯绿画面切换显示为纯蓝画面。若显示屏03当前显示的画面为纯绿画面,且用户点击了一次第二切换子控件Color-,则处理器01可以控制显示屏03从该纯绿画面切换显示为纯红画面。
当然,在一些其他实施例中,画面切换控件Color也不存在第一切换子控件Color+和第二切换子控件Color-之分,相应的,仅可以包括一种颜色切换顺序。处理器01可以根据针对画面切换控件Color的一次点击操作,控制显示屏03切换显示一次颜色。假设共包括4种不同颜色的画面,则在由第1种颜色的画面切换显示至第4种颜色的画面后,可以再控制显示屏03由第4种颜色的画面切 换显示至第1种颜色的画面,以此类推。
可选的,参考图11,本公开实施例记载的显示装置还可以包括:第一驱动电路04和第二驱动电路05。其中,处理器01还可以与第一驱动电路04连接,第一驱动电路04还可以与第二驱动电路05连接,第二驱动电路05还可以与背光源02连接。
在此基础上,继续参考图9可以看出,本公开实施例记载的触控控件还可以包括:烧写保存控件BS。即,结合图9,处理器01,还可以用于:响应于调节启动指令,在显示屏03上显示烧写保存控件BS。以及,用于根据接收到的针对烧写保存控件BS的第五触控操作,将根据第一亮度调节量调节后的亮度烧写并存储至第一驱动电路04中。
可选的,同第一触控操作,该第五触控操作也可以为针对烧写保存控件BS的点击操作。当用户对各个背光分区A1中发光元件L1的亮度调节完成之后,可以点击该烧写保存控件BS。此时,处理器01即可以接收到针对该烧写保存控件BS的第五触控操作,并可以根据该第五触控操作将调节后的亮度烧写并存储至第一驱动电路04中。示例的,第一驱动电路04可以为可编程阵列逻辑(field programmable gate array,FPGA)电路。FPGA电路一般包括存储器(flash),存储器也可以称为寄存器。处理器01可以将调节后的亮度存储至该寄存器中。
可选的,参考图12可知,烧写保存控件BS可以包括:相互独立的烧写控件Burning和保存控件Save。当调节亮度完成之后,用户可以先针对烧写控件Burning进行触控操作,再针对保存控件Save进行触控操作。此处记载的触控操作也均可以为点击操作。在此基础上,对于处理器01而言,处理器01可以用于先根据接收到的针对烧写控件Burning的触控操作将调节后的亮度烧写至第一驱动电路04中,再根据接收到的针对保存控件Save的触控操作将烧写后的亮度存储至寄存器中。再然后,用户可以通过触控和/或语音操作触发显示装置退出亮度调节状态,显示屏正常显示。如,显示屏上可以显示有针对亮度调节的关闭控件,用户可以通过点击该关闭控件触发显示装置退出亮度调节。
其中,保存至第一驱动电路04的亮度可以用于供第一驱动电路04驱动背光源01发光。即,第一驱动电路04,可以用于:根据存储的亮度控制第二驱动电路05向背光源02传输驱动电流,以驱动背光源02中的多个发光元件L1发光。该存储的亮度可以作为驱动背光源02发光的基准亮度。即,第一驱动电路 04可以基于该基准亮度(即,存储的亮度)控制第二驱动电路05点亮背光源。
示例的,第一驱动电路04可以基于存储的亮度向第二驱动电路05传输能够指示该亮度的占空比信号,以指示第二驱动电路05灵活输出驱动电流,点亮背光源02。换言之,在显示屏03正常显示状态下,可以基于调节后的亮度灵活驱动背光源02发光,改善背光源02的发光效果。如,假设保存至第一驱动电路04的亮度满足图9所示结果,则第一驱动电路04和第二驱动电路05在配合驱动背光源01正常工作时,可以基于图9所示结果点亮背光源02。
需要说明的是,为便于用户观看亮度,在进入亮度调节时,处理器01可以在显示屏上显示十进制的亮度参数,如图9所示的“127”和“126”等参数。而因FPGA电路一般保存的是十六进制数据,故最终烧写并保存至FPGA电路(即,第一驱动电路04)亮度可以为十六进制。如,假设调节后的亮度为十进制数“124”,则保存至第一驱动电路04的亮度即可以为十六进制数“7c”。
以及,处理器01可以集成于芯片系统(system-on-a-chip,SOC)中。SOC可以通过I2C协议与FPGA电路通信连接。SOC用于读写FPGA电路中的数据。即,读取FPGA flash中的数据,并将调节后的亮度烧写至FPGA电路中固化。
可选的,结合上述实施例记载可知,每个背光分区A1可以具有多个子分区,每个子分区包括至少一个发光元件。其中,第二驱动电路05可以具有多个电流传输通道,第二驱动电路05可以用于:通过多个电流传输通道向多个子分区分别传输驱动电流,从而实现局部调光的目的。
可选的,继续参考图9可以看出,本公开实施例记载的触控控件还可以包括:亮度读取控件Read。即,结合图9,处理器01,还可以用于:响应于调节启动指令,在显示屏上显示亮度读取控件Read。以及,用于根据接收到的针对的第六触控操作,显示第一驱动电路01中存储的亮度,以供用户可靠查看,改善用户体验。结合图9,可以是在显示屏03上显示存储的亮度,或者如上述实施例记载,也可以在显示装置外接的控制设备中显示该存储的亮度。
可选的,参考图13,本公开实施例记载的显示装置还可以包括:亮度传感器S1,亮度传感器S1可以位于背光源02一侧且与第一驱动电路04连接(图中未示出)。
其中,亮度传感器S1,可以用于:检测多个发光元件L1的发光亮度,并将检测到的发光亮度传输至第一驱动电路04。在此基础上,第一驱动电路04,还 用于:基于亮度传感器S1传输的发光亮度,控制第二驱动电路05校正传输至背光源02的驱动电流。如,若在基于根据第一亮度调节量调节后的亮度驱动背光源02发光过程中,背光源02发光亮度仍然出现异常。则可以通过该亮度传感器S1、第一驱动电路04和第二驱动电路05相互配合,以实现亮度校正,确保显示装置的显示效果可以较好。
当然,在一些其他实施例中,也可以直接通过该亮度传感器S1、第一驱动电路04和第二驱动电路05相互配合,实现背光分区A1的亮度调节。此时,亮度调节方法可以不用在每次组装灯板制造背光源时进行物理尺寸确认,组装完成后调试即可。然而,亮度传感器S1的设置成本较高,不适合量产。
可选的,参考图2和图5,本公开实施例记载的背光源02可以包括拼接的多个灯板021,每个灯板021可以具有至少两个背光分区A1。在此基础上,每相邻两个灯板021之间即具有拼缝f1。在本公开实施例中,如图12所示,亮度传感器S1可以位于多个灯板021的拼缝处,以可靠检测多个灯板021靠近拼缝f1位置处的发光亮度,相应的可知,可以包括多个亮度传感器S1。因拼缝f1处亮度易出现异常,故可以实现对亮度异常的及时校正,确保显示效果能够较好。
可选的,本公开上述实施例记载的所有控件均可以为图9所示显示于显示屏上的虚拟控件。当然,在一些其他实施例中,一个或多个控件也可以为设置于显示装置上的实体按键。以及,结合图2、图9和图12,在本公开实施例中,背光源02包括的多个灯板021可以在显示屏03上阵列排布。第二亮度调节控件(包括Num+和Num-)、亮度重置控件Reset、画面切换控件(包括Color+和Color-)、烧写控件Burning和保存控件Save可以沿灯板行方向X依次排布,且与多个灯板沿灯板列方向Y依次排布。当然,各个控件和灯板021也可以满足其他排布方式,本公开实施例对该排布方式并不作限定。
需要说明的是,本公开实施例中,处理器01执行的亮度调节方法可以在显示装置还未出厂前的测试阶段进行,在此基础上,上述实施例记载的用户可以为显示装置的制造工程师。或,处理器01执行的亮度调节方法还可以在显示装置出厂后进行,在此基础上,上述实施例记载的用户可以为使用显示装置的人。
结合上述实施例记载,以及图9和图12所示显示屏03界面示意图可知,本公开实施例提供的处理器01可以用于执行下述操作:
(1)Reset重置功能:将各个背光分区A1中发光元件L1的亮度均重置为 相同的基准亮度,如128。
(2)Read读取功能:读取第一驱动电路04的寄存器中现有存储的亮度。
(3)Color+/Color-画面背景色切换功能:控制显示屏03切换显示不同颜色的画面。
(4)J11+/J11-亮度分区调节功能:基于第一亮度调节量单独调节各个背光分区A1中多个发光元件L1的亮度。
(5)Num-/Num+亮度整体调节功能:基于第二亮度调节量统一且同时调节每个背光分区A1中多个发光元件L1的亮度。
(6)Burning烧写功能:将调节后的亮度烧写至FPGA中固化。
(7)Save保存功能:保存调节后的亮度。
在上述内容基础上,结合图6和图9,对调节亮度内容举例如下:
当用户观察到第一方向X,即灯板行方向上,相邻两个灯板021的拼缝f1之间出现竖向亮线,则可以针对该相邻两个灯板021中,第三背光分区A1-3和第一背光分区A1-1的第一亮度减子控件J11-进行第一触控操作,以降低第一背光分区A1-1的亮度和第三背光分区A1-3的亮度,从而达到改善竖向亮线的目的。如,假设是灯板021-2与其相邻的灯板021-1之间的拼缝f1,以及灯板021-2与其相邻的灯板021-3之间的拼缝f1,均出现竖向亮线。则,可以降低灯板021-2中第一背光分区A1-1的亮度和第三背光分区A1-3的亮度,降低灯板021-1中第一背光分区A1-1的亮度,降低灯板021-3中第三背光分区A1-3的亮度。
当用户观察到第一方向X上,相邻两个灯板021的拼缝f1之间出现竖向暗线,则可以针对该相邻两个灯板021中,第二背光分区A1-2和第四背光分区A1-4的第一亮度减子控件J11-进行第一触控操作,以降低第二背光分区A1-2的亮度和第四背光分区A1-4的亮度,从而达到改善该竖向暗线的目的。如,假设是灯板021-2与其相邻的灯板021-1之间的拼缝f1出现竖向暗线。则,可以降低灯板021-2中第二背光分区A1-2的亮度和第四背光分区A1-4的亮度,且降低灯板021-1中第二背光分区A1-2的亮度和第四背光分区A1-4的亮度。
当用户观察到第二方向Y,即灯板列方向上,相邻两个灯板021的拼缝f1之间出现横向亮线,则可以针对该相邻两个灯板021中,第四背光分区A1-4的第一亮度减子控件J11-进行第一触控操作,以降低第四背光分区A1-4的亮度,从而达到改善该横向亮线的目的。如,假设是灯板021-1与其相邻的灯板021-5 之间的拼缝f1出现横向亮线。则,可以降低灯板021-1中第四背光分区A1-4的亮度,且降低灯板021-5中第四背光分区A1-4的亮度。
当用户观察到第二方向Y上,相邻两个灯板021的拼缝f1之间出现横向暗线,则可以针对该相邻两个灯板021中,第一背光分区A1-1、第三背光分区A1-3和第二背光分区A1-2的第一亮度减子控件J11-进行第一触控操作,以降低第一背光分区A1-1的亮度,降低第三背光分区A1-3的亮度,且降低第二背光分区A1-2的亮度,从而达到改善该横向暗线的目的。如,假设是灯板021-1与其相邻的灯板021-5之间的拼缝f1出现横向暗线。则,可以降低灯板021-1中第一背光分区A1-1的亮度、第三背光分区A1-3的亮度和第二背光分区A1-2的亮度,且降低灯板021-5中第一背光分区A1-1的亮度、第三背光分区A1-3的亮度和第二背光分区A1-2的亮度。
以上仅是通过降低亮度来达到改善显示异常的目的。在一些其他实施例中,也可以通过增大亮度来改善显示异常,原理同上,不再赘述。在65寸显示装置项目验证中发现,若拼缝f1处亮度降低10尼特(Nit)左右,通过FPGA电路进行微调,将亮度参数128降低至124至122之间,可以改善显示效果。128降低至124至122之间对应十六进制即为:80降低至7c至7a之间。换言之,若出现暗线,非暗线区域亮度降低10Nit左右,不会影响整体显示效果。调节完成后,用户可以点击画面切换控件Color+/Color-,使得处理器01控制显示屏03切换显示如纯白、纯红、纯绿和纯蓝等不同颜色画面,若各个颜色画面显示效果均可以,则用户即可以进一步点击烧写控件Burning,将调节后的亮度烧写固化并保存至FPGA中。然后,用户可以结束亮度调节。
结合上述实施例可知,本公开实施例通过对背光源02中每个灯板021的各个背光分区A1亮度进行独立调节控制,可以改善拼缝f1处的亮度,确保显示效果较好。本公开实施例提供的上述方法可以解决因灯板组装公差或定位公差造成拼缝间距较大,而导致LCD面板出现亮线或暗线显示异常的问题;以及还可以解决因驱动电流差异而造成的色差异常问题。可以提高LCD面板的画面显示均一性,同时可以提高整机生产良率,无需拆机更换灯板,也相应的提高了生产效率。并且,本公开实施例提供的上述调节方法可以应用于各种不同尺寸显示装置中,尤其是大尺寸(如,65寸)的灯板数量较多的显示装置中。
可选的,本公开实施例记载的显示装置可以为:LCD装置、手机、平板电 脑、电视机、显示器、笔记本电脑或导航仪等任何具有显示功能的产品或部件。
