Description

柔光灯带、显示模组及移动终端 技术领域
本发明涉及移动终端领域，具体涉及一种柔光灯带、显示模组及移动终端。
背景技术
随着人们对自拍需求的提升，现阶段几乎所有的移动终端(如：智能手机、笔记本电脑、平板电脑等)都具有前置摄像头功能。伴随前置摄像头的闪光灯，由于闪光灯对人眼的刺激比较大，随着科学技术的不断发展，闪光灯逐渐被柔光灯所替代。
但是，目前的前置摄像头功能中柔光自拍方式比较简单，仅仅将闪光灯的出光孔径变大，对透镜进行雾化处理，容易造成自拍效果不好，同时在工业设计时，在正面触摸面板开孔不利于设备外形的美观设计。
发明内容
本发明实施例提供一种柔光灯带、显示模组及移动终端，以期增加前置摄像头的补光面积，提供更好的自拍效果，同时，也减少开孔，保证移动终端的美观。
本发明实施例第一方面，提供了一种柔光灯带，包括：
PCB板、多个闪光灯、导光膜和透镜，其中，所述多个闪光灯呈阵列排布在所述PCB上方，所述导光膜覆盖在所述多个闪光灯上方，用于实现将由所述多个闪光灯形成的点光源转变为面光源，所述透镜位于所述导光膜上方。
采用本实现方式，多个闪光灯呈阵列排布在PCB上方，能够将点光源阵列化，有助于在将点光源变为面光源后，面光源均匀分布在平面上，提高了面光源的光源质量。透镜位于导光膜上方，对导光膜具有一定的保护作用，导光膜具有导光的效果，同时能够将多个闪光灯发出的点光源进行平面化处理，使之变成补光面积为所述导光膜面积的面光源，增加了前置摄像头的补光面积，使得光源更加均匀，对自拍效果具有一定的提升。

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，下面将对实施例或现有技术描述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。
图1为本发明实施例提供的一种柔光灯带的结构示意图；
图2为本发明实施例提供的驱动电路的电路图；
图3为本发明实施例提供了另一种柔光灯带的结构示意图；
图4为本发明实施例提供了一种显示模组的结构示意图；
图5为本发明实施例提供了一种移动终端的结构示意图。
具体实施方式
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。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置展示该短语并 不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
本发明实施例所描述移动终端可以包括智能手机(如Android手机、IOS手机、Windows Phone手机等)、平板电脑、掌上电脑、笔记本电脑、移动互联网设备(MID，Mobile Internet Devices)或穿戴式设备等，上述仅是举例，而非穷举，包含但不限于上述移动终端。
图1为本发明实施例提供的一种柔光灯带的结构示意图。请参阅图1，该柔光灯带包括：透镜10、导光膜11、多个闪光灯12、和PCB板13。
其中，所述多个闪光灯12呈阵列排布在所述PCB板13上方，所述多个闪光灯，即闪光灯个数至少为2个，例如，可以是4个或8个。
可选地，阵列排布例如可以为以下一种：长方形阵列、正方形阵列或平行四边形阵列等。
可选地，闪光灯可以位于上述阵列的顶点位置，也可以位于上述阵列的每边中点的位置。上述阵列的一种放置方式为阵列与PCB板13的位置一致，具体的以长方形为例进行说明：长方形阵列的长边与PCB板13的长边平行，长方形阵列的短边与PCB板13的短边平行。
可选地，所述导光膜11覆盖在所述多个闪光灯12上方，具体为：导光膜11设置在多个闪光灯12远离PCB板13的一侧，用于实现将由所述多个闪光灯形成的点光源转变为面光源。
例如，在拍照过程中，环境的光线较暗，需要对环境进行补光。常规方式是打开闪光灯，通过闪光灯进行补光，但是单个闪光灯的点光源，容易造成对被拍照物体的补光度不高，也很容易造成漏光，例如拍摄得到的照片能够达到补光的效果，但是容易出现在某个局部位置出现光线较亮，在某些局部位置又出现光线较暗，使照片看起来很不美观。在采用导光膜将点光源变为面光源后，面光源能将光线均匀的照射在被拍照物体上，能在一定程度上增强对被拍照物体的补光度，通过面光源也能很好的避免漏光的发生，例如拍摄得到的照片能够达到补光的效果，拍得的照片补光均匀，光线自然。
可选地，所述导光膜11厚度可小于0.12毫米。
可选地，所述透镜10位于所述导光膜11上方，所述透镜10用于保护导光膜11。
可选地，所述柔光灯带的透镜10呈条形分布。所述条形分布可以理解为：呈矩形分布或者呈不规则的多边形分布，其中不规则的多边形分布，以矩形为例，可以是：矩形的长边弯曲、矩形的短边弯曲或矩形的长边和短边至少一边弯曲。
可选地，所述透镜10为表面磨砂的透明玻璃片或透明塑胶片。
可选地，所述多个闪光灯12可发出不同颜色的灯光，所述颜色为红色、绿色或蓝色，用户可以自行设置需要的灯光颜色，从而通过驱动电路对闪光灯进行控制，得到所述颜色的灯光。
可选地，所述柔光灯带还包括驱动电路，用于实现采用并联驱动方式驱动所述多个闪光灯工作，所述控制电路还可以控制不同颜色的闪光灯发光。
如图2所示，图2为驱动电路的电路图。请参阅图2，所述驱动电路包括控制器20、具有IIC总线的芯片21和所述多个闪光灯22。
其中，所述控制器20与所述具有IIC总线的芯片21相连接，所述具有IIC总线的芯片21与所述多个闪光灯22相连接，所述控制器20，用于通过所述具有IIC总线的芯片21并联驱动所述多个闪光灯22。

可选的，控制器20通过调整具有IIC总线的芯片21的串行数据和串行时钟的时序，进而通过具有IIC总线的芯片21实现对闪光灯22的并行控制。
可选的，在光线比较暗的环境下，在拍照过程中使用柔光灯带进行补光，在按下拍照按钮后，控制器20通过I/O接口向具有IIC总线的芯片21发送串 行控制数据、通过OUT接口向具有IIC总线的芯片21发送时钟数据，具有IIC总线的芯片21接收到时钟数据和串行控制数据后，在下一个时钟的上升沿到来时，根据串行控制数据对闪光灯22进行并行控制。
可以看出，将多个闪光灯呈阵列排布在PCB上方，能够将点光源阵列化，有助于在将点光源变为面光源后，面光源均匀分布在平面上，提高了面光源的光源质量。透镜位于导光膜上方，对导光膜具有一定的保护作用，导光膜具有导光的效果，同时能够将多个闪光灯发出的点光源进行平面化处理，使之变成补光面积为与所述导光膜面积相等的面光源，增加了前置摄像头的补光面积，使得光源更加均匀，对自拍效果具有一定的提升。
