Description

背光结构以及显示装置 技术领域
本申请涉及显示器技术领域，具体涉及一种背光结构以及显示装置。
背景技术
常规LCD的色域值一般为72％NTSC(NTSC为北美制定的一种通行颜色标准，百分比为显示器与NTSC的可显示色彩面积比值，数值越大表示色域越高)，作为对比，OLED产品的色域一般可以达到110％NTSC，比LCD可做到的最高色域还要高，反映出来就是OLED的色彩表现总是比LCD要更丰富、艳丽。现有的LCD可以使用RGB三色LED组成的背光单元，通过选择合适的波长匹配OC(open cell，液晶面板)穿透谱，可实现约115％NTSC的超高色域；由于RGB LED发光效率低，且需要分别单独走线控制每颗R、G、B芯片(常规LED只需要连接一颗蓝光芯片，多了两倍的线路)，这样就带来了功耗高、系统复杂等新问题，使此方案难以实现量产。

需要说明的是，在本申请的一些实施例中，所述背光结构100应用于侧入式背光模组，此时所述背光结构100多数以灯条的形式存在。为了兼顾提高色域和减小占用体积，在一实施例中，请进一步参阅图5，所述背光结构100包括凹凸配合的第一基板4和第二基板5，所述第一基板4在第一方向F1上具有间隔设置的多个第一凸部，所述第二基板5在所述第一方向F1上具有间隔设置的多个第二凸部；其中，多个所述低色域白光源1对应分别设于多个所述第一凸部；多个所述高色域白光源2对应分别设于多个所述第二凸部。
需要说明的是，本申请对所述第一基板4和所述第二基板5的具体连接形式不做限制，只要是能将所述第一基板4和所述第二基板5进行拼接即可；具体地，在一实施例中，所述第一基板4和所述第二基板5通过粘胶拼接。
在本申请中，所述低色域白光源1包括所述低色域白光源包括WLED或者包覆有黄色荧光粉膜片的BLED；也就是说，所述低色域白光源1可以是发出白光的LED，也可以是发出蓝光的LED，并搭配黄色荧光粉膜片即可发出白光；WLED和BLED虽然色域较低，但是功耗也相对较低。
在本申请中，所述高色域白光源2包括RGB LED；需要说明的是，RGB LED为RGB三色LED，使用RGB LED组成的背光结构100，通过选择合适的波长匹配OC(open cell，液晶面板)穿透谱，可实现约115％NTSC的超高色域。
需要说明的是，上述两个技术特征，可以择一设置，也可以同时设置，具体，在一实施例中，上述两个技术特征同时设置，也即，所述低色域白光源1 包括WLED或者包覆有黄色荧光粉膜片的BLED，所述高色域白光源2包括RGB LED，多个WLED或者多个包覆有黄色荧光粉膜片的BLED与多个RGB LED交替设置，如此，能够提高显示装置的色域，从而提高显示装置的色彩表现；并且，将多个低色域白光源1与多个高色域白光源2交替设置，在提高显示装置的色域的前提下，不仅能够降低背光结构100的整体功耗水平和系统复杂程度，而且能够提升背光结构100的亮度，减少发热量。
在本申请的一些实施例中，所述背光结构100应用于直下式背光模组，此时所述背光结构100多数以灯板的形式存在；基于此，所述背光结构100还包括背板6；其中，所述多个低色域白光源1和所述多个高色域白光源2设于所述背板6，且所述多个低色域白光源1的出光侧和所述多个高色域白光源2的出光侧均朝背对所述背板6的一侧设置。
需要说明的是，上述背光结构100实施例中仅描述了上述结构，可以理解的是，除了上述结构之外，本申请实施例背光结构100中，还可以根据需要包括任何其他的必要结构，具体此处不作限定。
第二方面，本申请的实施例还提供一种显示装置，所述显示装置包括背光结构100，需要说明的是，所述背光结构100设置为上述的背光结构100，也就是说，所述背光结构100具有上述的背光结构100的所有实施例，所述显示装置也就具有上述背光结构100的所有实施例的全部技术特征，也就具有全部技术特征带来的所有有益效果，此处不再一一赘述。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上对本申请实施例所提供的一种背光结构进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
