The utility model belongs to the field of backlight, specifically refers to a light guide plate without fastening a narrow frame back light source, including iron, iron under the above from the bottom is provided with a reflective film, keep the box through the rubber light guide plate and a diffusion sheet, brightness enhancement film, on Zengguang tablets and black and white light shielding film. The reflection film through the double-sided adhesive paste on the back of the glue frame, one end of the light guide plate into the source, the source is provided with four uniformly spaced LED lamps, the four lamps and LED FPC cable connection, outside the FPC cable extends to the lower formwork, between the rubber frame and the frame on the connection through the buckle, the utility model has the advantages that the rubber shell design, long in the width direction without making buckles, the light guide plate corresponding without buckling, the edge of the plastic frame size, in injection molding, casting The utility model has the advantages that the road is more smooth and stable, and the product which is formed is more refined, and the assembly process is also changed from the previous operation of the front glue box and the light guide plate to the direct light guide plate, which saves the working time.
【技术实现步骤摘要】
本技术属于背光源领域,具体的是指一种导光板无卡扣窄边框背光源。
技术介绍
在目前,随着彩屏显示背光模组要求越做越窄、越做越薄,新的困难不断出现;如胶壳、导光板超薄难注塑成型,胶壳强度不够且易变形,胶壳与导光板组装困难,有卡扣产品配套组装后卡扣亮点难解决,以及组装生产效率低等一系列问题。
技术实现思路
本技术为了克服现有技术之不足,提出了一种导光板无卡扣窄边框背光源。本技术是通过下述技术方案来解决上述技术问题的。一种导光板无卡扣窄边框背光源,包括下铁架,下铁架上面从下至上依次设置有通过胶框保持的反射膜、导光板、扩散片、下增光片、上增光片和黑白遮光膜,反射膜通过双面胶粘贴在胶框的背面,导光板的一端为进光源端,所述进光源端安装有四个均匀间隔分布LED灯,所述四个LED灯与FPC排线连接,FPC排线延伸至下铁架以外,所述胶框与上铁架之间通过卡扣连接,所述导光板与进光源端相对的另一端设多个梯形凸台,所述胶框内侧设置有与导光板的梯形凸台和四个LED灯相配的容置槽。更具体的,所述导光板与胶框接触的边缘设有定位孔,所述胶框上设有与定位孔相配的定位柱。更具体的,多个梯形凸台的数量为2个。更具体的,所述多个梯形凸台均匀间隔分布在导光板一端面。更具体的,所述胶框边缘的宽度为0.15mm。更具体的,所述四个LED灯通过双面胶粘附在导光板的进光源端。本技术的有益效果在 ...
