Description

一种自发光阵列显示控制方法及装置、设备 技术领域
本发明涉及屏幕显示技术领域，尤其涉及一种自发光阵列显示控制方法及装置、设备。
背景技术
常用的显示屏技术主要采用液晶显示器(英文：Liquid Crystal Display，简称：LCD)和有机发光二极管(英文：Organic Light-Emitting Diode，简称：OLED)，它们最主要的差别是：LCD是基于背光板发光，并通过显示面板选择性通过需要的光线，实现彩色图案输出，所以画面中无论内容如何，功耗都不变；而OLED是基于自发光原理，每个像素点都是自发光光源，所以显示画面中黑色像素越多，则开启的发光点越少，功耗越低。OLED是一种常见的自发光阵列，自发光阵列由多个发光二极管(英文：Light-Emitting Diode，简称：LED)构成。
根据排列和包含的发光二极管的不同，自发光阵列一般又分为红、绿、蓝排列(英文：RGB Pentile)与红、绿、蓝、白排列(英文：RGBW Pentile)，即红、绿、蓝、白排列相比红、绿、蓝排列增加了白色发光二极管，但是，采用红、绿、蓝、白排列的显示屏一般用于室外大屏幕，在使用时，没有低功耗要求，白色发光二极管一般用于增加画面亮度。
而对于终端设备，则要求尽量降低屏幕的功耗，以提高其续航能力，例如，OLED屏幕除了常规的全彩色显示模式以外，终端设备上常采用减少发光像素点数量的方法达成降功耗的目的，即采用低功耗显示模式。如图1所示的穿戴式设备OLED屏幕常规显示模式和低功耗显示模式示意图，常规显示的时候是RGB 400x400分辨率的图像，在低功耗模式时显示的是256灰阶400x400分辨率的图像，并把背景设为黑色，大幅减少发光点数量，达到降低功耗的目的。
但是，现有技术中的低功耗模式下功耗还是不够低，业界渴求着一种使得自发光阵列显示屏工作在低功耗模式下时功耗较低的方案。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施 例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
对于自发光阵列工作在低功耗显示模式下时，画面发白光，如图2所示的采用现有的红、绿、蓝发光二极管发白光的示意图，使用现有自发光阵列，发出白光要同时点亮像素点的三个LED，例如红、绿、蓝LED，虽然把背景设为黑色可以增加黑色像素点，有效减少需要发光的像素点数量，但每个发白光的像素点由于需要同时点亮红、绿、蓝三个LED，使得每个发白光的像素点功耗比像素点常规显示时功耗更高。
本发明实施例提供一种自发光阵列显示控制方法及装置、设备，通过使用白色发光二极管替代多个不同颜色的非白色发光二极管组合实现白色发光点发光，使得自发光阵列显示屏工作在低功耗模式下时的功耗较低。本发明实施例涉及的自发光阵列显示控制方案主要应用于各类终端设备显示控制。各类终端设备可以包括手机、可穿戴设备(如智能手表、智能手环等)、平板电脑、个人电脑、个人数字助理、销售终端、车载电脑等。
图3为本发明实施例提供的一种自发光阵列显示控制方法的流程示意图，在本实施例中，自发光阵列包括多个像素点，每个像素点包括非白色发光点和 白色发光点，所述非白色发光点和白色发光点下分别排列有非白色发光二极管和白色发光二极管，非白色发光二极管例如是红、绿、蓝发光二极管。
对于RGB排列的自发光阵列，在图像常规显示时，一个像素点的非白色发光点由三种不同颜色LED组成，但不一定每个像素点都由三个不同颜色LED组成，有可能相邻像素点合用一个非白色LED，例如两个像素点用5个非白色LED组成(即2个红色，2个绿色，1个蓝色)的组合。本实施例采用RGBW排列的自发光阵列，即增加了一个白色发光点，白色发光点通过白色发光二极管发光，且在本实施例中，白色发光二极管可以在普通显示模式下用于增加画面亮度，也可以用于显示屏工作在低功耗模式下时降低显示屏的功耗。
图3所示的方法包括以下步骤：
S101，当接收到图像的灰阶显示指令时，控制与白色发光点对应的白色发光二极管发光。
为了节省终端设备的功耗，用户设置终端设备的显示屏工作在低功耗模式下，从而向显示控制模块发送灰阶显示指令，终端设备的显示屏采用自发光阵列，当显示屏显示灰阶图像时，只有黑色和白色两种像素点，白色像素点仅白色发光点发光，非白色发光点不发光，且本实施例中，当接收到图像的灰阶显示指令时，控制与白色发光点对应的白色发光二极管发光。
以400x400x24bit显示规格的OLED显示屏为例，常规模式下，显示图像为400x400x24bit的图像，实际的发光像素点数为M，实际发光LED数为3M，M为正整数；而在低功耗模式下且采用多个不同颜色的非白色发光二极管组合实现白色发光点发光时，显示图像为400x400的256灰阶图像，并通过把背景图设为全黑，把实际发光像素点数降低为N，实际发光LED降低为3N，其中N为正整数且N<M，即将图像的背景设置为全黑，将背景设为黑色可以增加黑色像素点，黑色像素点所在的LED不发光，可以有效减少需要发光的像素点数量。而本实施例中，自发光阵列工作在低功耗模式下，低功耗模式下显示屏显示灰阶图像，仅白色发光点被点亮，且本实施例利用白色发光二极管实现灰阶图像，即控制与白色发光点对应的白色发光二极管发光。可选地，控制与所述白色发光点的数量和位置一一对应的白色发光二极管发光。仍以前面示例为例，低功耗模式下，控制与所述白色发光点的数量和位置一一对应的白色发光二极管发光，实际发光点为N个白光二极管，比采用多个不同颜色的 非白色发光二极管组合实现白色发光点发光相比，只用了N个发光二极管，在忽略其它因素的情况下，显示屏功耗降低了将近2/3。
作为S101的一种实现方式，当接收到图像的灰阶显示指令时，控制与所述白色发光点的数量和位置一一对应的白色发光二极管发光。本实施例中，每个像素点下面布置有一个白色LED，确定需要发白光的像素点(即该像素点包括需要点亮的白色发光点)的数量和位置，控制与该白色发光点的数量和位置一一对应的白色发光二极管发光。如图4所示，为示例的一种自发光阵列排列示意图，在该排列中，一个像素点包括红、蓝、绿、白四个发光点，红、蓝、绿、白四个发光点下面对应设置有红、蓝、绿、白四个发光LED，在显示灰阶图像时，仅白色发光点发光，本实施例中，控制与需要发光的白色发光点的数量和位置一一对应的白色LED发光。在图4中，彩色分辨率为L×K，白色分辨率也为L×K。
当然，控制与白光发光点对应的白色发光二极管发光，对于自发光阵列的白色发光二极管采用的排列方式不同，还可以是其它的实现方式，在此不作限制。
根据本发明实施例提供的一种自发光阵列显示控制方法，通过使用白色发光二极管替代多个不同颜色的非白色发光二极管组合实现白色发光点发光，使得自发光阵列显示屏工作在低功耗模式下时的功耗较低。
图5为本发明实施例提供的另一种自发光阵列显示控制方法的流程示意图，该方法包括以下步骤：
S201，当接收到图像的灰阶显示指令时，确定多个像素点中白色发光点位置相邻的至少两个像素点，所述至少两个像素点中的白色发光点合用一个白色发光二极管。
S202，控制合用的所述白色发光二极管发光。
自发光阵列的一个像素点包括多个非白色发光点和白色发光点，本实施例中，在排列自发光阵列时，可以设置两个或两个以上像素点的白色发光点位置相邻。如图6示例的合用白色发光二极管的自发光阵列排列示意图，红、蓝、绿、白四个发光点构成一个像素点，在图6的左图中，像素点A和像素点B的白色发光点位置相邻，在像素点A和像素点B的白色发光点下对应设置一 个白色发光二极管，即像素点A和像素点B的白色发光点合用一个白色发光二极管，控制该合用的白色发光二极管发光，在左图中，彩色分辨率为L×K，白色分辨率为L/2×K；在图6的右图中，像素点A、B、C、D的白色发光点位置相邻，在像素点A、B、C、D的白色发光点下对应设置一个白色发光二极管，即像素点A、B、C、D的白色发光点合用一个白色发光二极管，控制该合用的白色发光二极管发光，在右图中，彩色分辨率为L×K，白色分辨率为L/2×K/2。
以400x400x24bit显示规格的OLED显示屏为例，常规模式下，显示图像为400x400x24bit的图像，实际的发光像素点数为M，实际发光LED数为3M，M为正整数；而在低功耗模式下且采用多个不同颜色的非白色发光二极管组合实现白色发光点发光时，显示图像为400x400的256灰阶图像，并通过把背景图设为全黑，把实际发光像素点数降低为N，实际发光LED降低为3N，其中N为正整数且N<M；而在本实施例中，即低功耗模式且控制白色发光点位置相邻的多个像素点合用一个白色发光二极管发光，例如白色发光点相邻的四个像素点合用一个白色发光二极管，若整个自发光阵列中每四个像素点的白色发光点都相邻，相邻的白色发光点合用一个白色发光二极管，则实际发光二极管为N/4个发光二极管，比原有技术相比，只用了1/12的发光二极管，减少了发光二极管数量，进一步降低了显示屏功耗。
仍以图6为例，为了达到不同程度的功耗的降低，可以降低到不同的白色分辨率，根据降低的白色分辨率的不同，采用不同的自发光阵列的排列。
S203，调节所述白色发光二极管的亮度实现设定灰阶等级。
灰阶图像按照发光亮度不同划分为不同的等级，一般有256个等级，因此，可以调节白色发光二极管的亮度以实现设定不同的灰阶等级。
S204，将所述图像的背景设置为全黑。
这里，自发光阵列工作在低功耗模式下时，显示屏显示灰阶图像，将图像的背景设置为全黑是指控制像素点中除需要发光的白色发光点发光外，控制像素点中的其它非白色发光二极管不发光。把图像的背景设置为全黑，可以增加黑色像素点，对于自发光阵列来说，可以有效减少需要发光的像素点数量，从而进一步降低显示屏的功耗。
根据本发明实施例提供的一种自发光阵列显示控制方法，通过使用白色发 光二极管替代多个不同颜色的非白色发光二极管组合实现白色发光点发光，使得自发光阵列显示屏工作在低功耗模式下时的功耗较低；且通过控制白色发光点位置相邻的多个像素点合用一个白色发光二极管，减少了发光二极管的数量，进一步降低了显示屏的功耗。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明并不受所描述的动作顺序的限制，因为根据本发明，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本发明所必须的。
图7为本发明实施例提供的一种自发光阵列显示控制装置的结构示意图，在本实施例中，自发光阵列包括多个像素点，每个像素点包括非白色发光点和白色发光点，所述非白色发光点和白色发光点下分别排列有非白色发光二极管和白色发光二极管，非白色发光二极管例如是红、绿、蓝发光二极管。
对于RGB排列的自发光阵列，在图像常规显示时，一个像素点的非白色发光点由三种不同颜色LED组成，但不一定每个像素点都由三个不同颜色LED组成，有可能相邻像素点合用一个非白色LED，例如两个像素点用5个非白色LED组成(即2个红色，2个绿色，1个蓝色)的组合。本实施例采用RGBW排列的自发光阵列，即增加了一个白色发光点，白色发光点通过白色发光二极管发光，且在本实施例中，白色发光二极管可以在普通显示模式下用于增加画面亮度，也可以用于显示屏工作在低功耗模式下时降低显示屏的功耗。
图7所示的装置1000包括：
控制单元11，用于当接收到图像的灰阶显示指令时，控制与白色发光点对应的白色发光二极管发光。
为了节省终端设备的功耗，用户设置终端设备的显示屏工作在低功耗模式下，从而向显示控制模块发送灰阶显示指令，终端设备的显示屏采用自发光阵列，当显示屏显示灰阶图像时，只有黑色和白色两种像素点，白色像素点仅白色发光点发光，非白色发光点不发光，且本实施例中，当接收到图像的灰阶显示指令时，控制与白色发光点对应的白色发光二极管发光。
以400x400x24bit显示规格的OLED显示屏为例，常规模式下，显示图像 为400x400x24bit的图像，实际的发光像素点数为M，实际发光LED数为3M，M为正整数；而在低功耗模式下且采用多个不同颜色的非白色发光二极管组合实现白色发光点发光时，显示图像为400x400的256灰阶图像，并通过把背景图设为全黑，把实际发光像素点数降低为N，实际发光LED降低为3N，其中N为正整数且N<M，即将图像的背景设置为全黑，将背景设为黑色可以增加黑色像素点，黑色像素点所在的LED不发光，可以有效减少需要发光的像素点数量。而本实施例中，自发光阵列工作在低功耗模式下，低功耗模式下显示屏显示灰阶图像，仅白色发光点被点亮，且本实施例利用白色发光二极管实现灰阶图像，即控制与白色发光点对应的白色发光二极管发光。可选地，控制与所述白色发光点的数量和位置一一对应的白色发光二极管发光。仍以前面示例为例，低功耗模式下，控制与所述白色发光点的数量和位置一一对应的白色发光二极管发光，实际发光点为N个白光二极管，比采用多个不同颜色的非白色发光二极管组合实现白色发光点发光相比，只用了N个发光二极管，在忽略其它因素的情况下，显示屏功耗降低了将近2/3。
作为一种实现方式，控制单元11具体用于当接收到图像的灰阶显示指令时，控制与所述白色发光点的数量和位置一一对应的白色发光二极管发光。本实施例中，每个像素点下面布置有一个白色LED，确定需要发白光的像素点(即该像素点包括需要点亮的白色发光点)的数量和位置，控制与该白色发光点的数量和位置一一对应的白色发光二极管发光。如图4所示，为示例的一种自发光阵列排列示意图，在该排列中，一个像素点包括红、蓝、绿、白四个发光点，红、蓝、绿、白四个发光点下面对应设置有红、蓝、绿、白四个发光LED，在显示灰阶图像时，仅白色发光点发光，本实施例中，控制与需要发光的白色发光点的数量和位置一一对应的白色LED发光。在图4中，彩色分辨率为L×K，白色分辨率也为L×K。
当然，控制与白光发光点对应的白色发光二极管发光，对于自发光阵列的白色发光二极管采用的排列方式不同，还可以是其它的实现方式，在此不作限制。
根据本发明实施例提供的一种自发光阵列显示控制装置，通过使用白色发光二极管替代多个不同颜色的非白色发光二极管组合实现白色发光点发光，使得自发光阵列显示屏工作在低功耗模式下时的功耗较低。
图8为本发明实施例提供的另一种自发光阵列显示控制装置的结构示意图，该装置2000包括：控制单元21、调节单元22和设置单元23。具体地：
控制单元21，用于当接收到图像的灰阶显示指令时，确定多个像素点中白色发光点位置相邻的至少两个像素点，所述至少两个像素点中的白色发光点合用一个白色发光二极管。
控制单元21还用于控制合用的所述白色发光二极管发光。
自发光阵列的一个像素点包括多个非白色发光点和白色发光点，本实施例中，在排列自发光阵列时，可以设置两个或两个以上像素点的白色发光点位置相邻。如图6示例的合用白色发光二极管的自发光阵列排列示意图，红、蓝、绿、白四个发光点构成一个像素点，在图6的左图中，像素点A和像素点B的白色发光点位置相邻，在像素点A和像素点B的白色发光点下对应设置一个白色发光二极管，即像素点A和像素点B的白色发光点合用一个白色发光二极管，控制该合用的白色发光二极管发光，在左图中，彩色分辨率为L×K，白色分辨率为L/2×K；在图6的右图中，像素点A、B、C、D的白色发光点位置相邻，在像素点A、B、C、D的白色发光点下对应设置一个白色发光二极管，即像素点A、B、C、D的白色发光点合用一个白色发光二极管，控制该合用的白色发光二极管发光，在右图中，彩色分辨率为L×K，白色分辨率为L/2×K/2。
以400x400x24bit显示规格的OLED显示屏为例，常规模式下，显示图像为400x400x24bit的图像，实际的发光像素点数为M，实际发光LED数为3M，M为正整数；而在低功耗模式下且采用多个不同颜色的非白色发光二极管组合实现白色发光点发光时，显示图像为400x400的256灰阶图像，并通过把背景图设为全黑，把实际发光像素点数降低为N，实际发光LED降低为3N，其中N为正整数且N<M；而在本实施例中，即低功耗模式且控制白色发光点位置相邻的多个像素点合用一个白色发光二极管发光，例如白色发光点相邻的四个像素点合用一个白色发光二极管，若整个自发光阵列中每四个像素点的白色发光点都相邻，相邻的白色发光点合用一个白色发光二极管，则实际发光二极管为N/4个发光二极管，比原有技术相比，只用了1/12的发光二极管，减少了发光二极管数量，进一步降低了显示屏功耗。
仍以图6为例，为了达到不同程度的功耗的降低，可以降低到不同的白色 分辨率，根据降低的白色分辨率的不同，采用不同的自发光阵列的排列。
调节单元22，用于调节所述白色发光二极管的亮度实现设定灰阶等级。
灰阶图像按照发光亮度不同划分为不同的等级，一般有256个等级，因此，可以调节白色发光二极管的亮度以实现设定不同的灰阶等级。
设置单元23，用于将所述图像的背景设置为全黑。
这里，自发光阵列工作在低功耗模式下时，显示屏显示灰阶图像，将图像的背景设置为全黑是指控制像素点中除需要发光的白色发光点发光外，控制像素点中的其它非白色发光二极管不发光。把图像的背景设置为全黑，可以增加黑色像素点，对于自发光阵列来说，可以有效减少需要发光的像素点数量，从而进一步降低显示屏的功耗。
根据本发明实施例提供的一种自发光阵列显示控制装置，通过使用白色发光二极管替代多个不同颜色的非白色发光二极管组合实现白色发光点发光，使得自发光阵列显示屏工作在低功耗模式下时的功耗较低；且通过控制白色发光点位置相邻的多个像素点合用一个白色发光二极管，减少了发光二极管的数量，进一步降低了显示屏的功耗。
图9为本发明实施例提供的一种自发光阵列显示控制设备的结构示意图，所述自发光阵列包括包括多个像素点，每个像素点包括非白色发光点和白色发光点，所述非白色发光点和白色发光点下分别排列有非白色发光二极管和白色发光二极管，非白色发光二极管例如是红、绿、蓝发光二极管。如图9所示，该设备3000可包括：
