具体实施方式
现有技术中的背光结构一般为矩形，其胶架条和黑黑胶分布于矩形的四个边，即分布于背光结构的所有边，因而现有技术的设计方案边框较宽。
本公开实施例提供了一种背光结构、显示装置，可以实现更窄边框的背光结构，进而使得应用该背光结构的显示装置实现超窄边框，使显示装置在外观上更为精致，视觉效果更佳，提高用户感受。
随着智能产品的普及，大屏的液晶显示装置越来越受欢迎，自然而然的单手操作与大屏之间的矛盾也显现出来，因而尽可能使得边框变窄可以减小机身宽度。超窄边框减小边框因而能够缓解单手操作与大屏之间的矛盾；而且超窄边框的显示装置屏占比高，在外观上更为精致，视觉效果更加佳。由于超窄边 框的应用，对背光结构的设计提出了更高的要求。
本公开实施例提供的一种背光结构，包括框架和设置在框架内的胶架条，框架具有多个边，多个边被配置为至少一个设置有胶架条的第一边和至少一个未设置有胶架条的第二边。
本公开实施例提供的背光结构，由于该背光结构的框架的多个边被配置为设置有胶架条的第一边和未设置有胶架条的第二边，即胶架条并没有分布于所有边，而是一部分，因此可以实现边框更窄的背光结构。进而，可以使得应用该背光结构的显示装置实现超窄边框，使显示装置在外观上更为精致，视觉效果更佳，提高用户感受。
其中，第一边与第二边个数不做限定，只要第一边的个数和第二边的个数大于等于1即可。例如，当框架为矩形时，第一边可以包括两个短边，第二边可以包括两个长边。此外，第一边可以包括一个短边和一个长边，第二边可以包括一个短边和一个长边。
可选地，框架选用金属框架，但不限于金属框架，也可以选择其他材料，例如，塑料等其他材料。
可选地，金属框架的形状可以选择矩形但不限于矩形，例如，菱形等其他形状。例如，第一边或第二边可以是带有弧度的边。
可选地，当本公开实施例中所述框架为矩形框架时，本公开实施例中所述胶架条可以设置在该框架的短边处，即长边没有胶架条，胶架条不在长边方向上增加背光结构的长边的横向宽度。本公开实施例提供的背光结构仅在矩形框架的短边处设置胶架条，可以使得背光结构变窄，使得应用背光结构的显示面板变窄，最终使得应用显示面板的显示装置实现超窄结构。
可选地，本公开实施例提供的背光结构还包括设置在框架内的膜材，以及用于封装该膜材的黑黑胶。并且，可选地，该黑黑胶也封装在框架的第一边，即与胶架条的位置相对应，从而可以进一步保证实现超窄边框的背光结构，即长边也没有黑黑胶，黑黑胶不在长边方向上增加背光结构的长边的横向宽度。
可选地，所述膜材包括设置在所述框架的背板之上的导光板、所述胶架条与所述导光板之间的发光组件、设置在所述导光板与所述框架的背板之间的反射片、以及依次设置在所述导光板上方的扩散膜、下增光片以及上增光片。
当然，本公开实施例提供的背光结构还可以包括其他结构部件，所述膜材也可以包括其他膜层等，在此不再赘述。
下面以矩形背光结构为例，结合附图介绍本公开实施例中提供的一个具体的背光结构。
如图1所示，本公开实施例中提供的一种矩形的背光结构，包括金属框架101和设置在金属框架101内的胶架条102，金属框架101为矩形，胶架条102设置在金属框架101的短边处。
需要说明的是，可选地，本公开实施例中将胶架条102仅设置在金属框架101的两个短边处。但是，在其他实施例中，胶架条102也可以设置在长边处，例如：两个短边与一个长边设置胶架条102，或者两个长边设置胶架条102，或者，也可以只有一个短边或一个长边设置胶架条102。由于没有在整个框架的所有边框都设置胶架条102，因而可以节省空间，使得背光结构实现更窄的边框(这种设计可以称为超窄边框设计)。
可选地，该背光结构还包括设置在金属框架101内的膜材，以及用于封装膜材的黑黑胶109，黑黑胶109封装在金属框架101的短边。
可选地，膜材可以包括设置在框架101的背板之上的导光板104、胶架条102与导光板104之间的发光组件105、设置在导光板104与框架101的背板之间的反射片103、依次设置在导光板104上方的扩散膜106、下增光片107以及上增光片108。在其他实施例中扩散膜106可以是扩散片106。
可选地，如图7和图8所示，发光组件105包括灯条105-3和柔性线路板(Flexible Printed Circuit，FPC)105-1，灯条105-3设置在导光板104的入光口处，发光侧的胶架条102上设有凹槽110，灯条105-3通过例如自带的双面胶105-2粘贴在凹槽110中。
可选地，扩散膜106通过双面胶与导光板104贴合固定，上增光片108与下增光片107靠近发光组件105的一侧为锯齿状，上增光片108与下增光片107的锯齿状部分通过黑黑胶109与导光板104贴合固定。
图2示出根据本公开一个实施例的发光组件的示意图。如图2所示，柔性电路板201位于背光结构的发光侧，背光结构的短边设置有黑黑胶109。
本公开提供的一种显示装置，包括本公开提供的任一背光结构，还包括显示面板，显示面板通过在金属框架101的侧边涂胶与所述背光结构的侧边贴合固定。
图3示出根据本公开一个实施例的显示装置的示意图。如图3所示，本公开的实施例提供的显示装置包括显示面板302和背光结构303，侧面涂胶301位于显示面板302与背光结构303的长边位置和与发光侧相对的短边处，即可以采用U型的侧面涂胶方式将显示面板302和背光结构303贴合固定。
具体地，沿虚线AA′切割后，如图4所示，显示面板302包括：上偏光片(Polarizer，POL)401、阵列基板(Thin-Film Transistor substrate，TFT基板)402、彩膜基板(Color Film substrate，CF基板)403、下偏光片404、以及封框胶405；阵列基板402与彩膜基板403通过封框胶405将四周的边框进行贴合固定；显示面板302设置在背光结构303上方，背光结构303由下至上依次包括金属框架101、反射片103、导光板104、扩散膜106、下增光片107、上增光片108；由图4可见，在背光结构303与显示面板302的侧面，即长边处设置有涂胶301，用于将显示面板302与背光结构303进行贴合固定。
本公开实施例提供显示装置中，显示面板302为矩形结构，其可以通过两个长边涂胶与背光结构303的两个长边贴合固定，再或者可以通过两个长边和与发光侧相对的短边涂胶与背光结构303的两个长边和发光侧相对的短边贴合固定(即采用U型涂胶将显示面板302和背光结构303贴合固定)，当然，也可以在四周都涂胶，即围绕矩形涂一圈胶，用来固定显示面板302和背光结构303。
可选地，涂胶301为至少能够部分遮光的涂胶301。
可选地，使用至少能够部分遮光的涂胶301，能够避免显示装置各边的漏光问题，涂胶301可以采用黑色的光敏胶(Ultraviolet Rays glue，UV胶)、热固胶、塑料胶等，这里不作限定。
可选地，如图5和图6所示，显示面板302为矩形，有三个边通过设置在长边侧面的涂胶301与背光结构303的三个边贴合固定，三个边，分别是两个长边和与发光侧相对的短边。
通过将显示面板302的两个长边、与发光侧相对的短边和背光结构303与之相对应的三个边贴合固定能够防止显示装置两个长边与短边相接的地方漏光，三条边进行贴合固定，遮光效果更佳，从而可以很好地防止漏光，保证背光结构303的边缘不会存在漏光。
可选地，背光结构303的短边的长度，小于或等于显示面板302的短边的长度，如图3～4所示，本公开实施例采用背光结构303相比显示面板302在宽度上的内缩设计，背光结构303的短边长度比显示面板302的短边长度内缩0.1mm，通过侧边涂胶技术使显示面板302与背光结构303相固定，胶水形成的宽度约为0.1mm，显示面板302的边框为0.5mm，从而实现整个显示装置的超窄边框。本公开实施例提供的显示装置，背光结构与显示面板间采用内缩设计，将本公开实施例中的背光结构的变窄，从而使背光结构与显示面板贴合固定后的宽度整体变窄，实现显示装置的超窄边框。
本公开实施例提供的一种显示装置，包括通过该背光结构303实现超窄边框的显示面板302，所述背光结构303为本公开实施例提供的任一所述的背光结构303，所述显示面板302为本公开实施例提供的任一所述的显示面板302。
例如，所述的显示装置为手机、PAD、电脑、电视等等具有显示功能的产品。
综上所述，本公开实施例提出了一种实现显示面板超窄边框的背光设计，包括背光结构和显示面板的结构设计以及两者的组装，背光结构包括金属框架 和设置在金属框架内的胶架条，本公开实施例将背光结构的胶架条设置在金属框架的短边，黑黑胶固定膜材在金属框架的短边处，去掉了背光结构长边的胶架条和黑黑胶，实现背光结构的超窄边框；背光结构内缩于显示面板，利用侧面涂胶将显示面板与背光结构贴合固定，使得显示装置实现超窄边框。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
