本实用新型涉及液晶显示设备技术领域，尤其涉及一种背光源结构及显示面板。The utility model relates to the technical field of liquid crystal display equipment, in particular to a backlight source structure and a display panel.
背景技术Background technique
液晶显示装置为目前最广为使用的显示装置产品，液晶显示装置是由液晶面板的液晶层以控制各像素位置的光线透射率，使液晶显示装置能够正确地显示影像。由于液晶显示装置中的液晶面板不能自发光，因此需要背光模块以提供液晶面板所需的光源，使液晶显示装置达到显示的效果。The liquid crystal display device is currently the most widely used display device product. The liquid crystal display device controls the light transmittance of each pixel position by the liquid crystal layer of the liquid crystal panel, so that the liquid crystal display device can display images correctly. Since the liquid crystal panel in the liquid crystal display device cannot emit light by itself, a backlight module is needed to provide the light source required by the liquid crystal panel, so that the liquid crystal display device can achieve the display effect.
目前，在液晶显示设备技术的发展上，窄边框设计的液晶显示设备能够在有限的空间内提供更大的观看视角，是液晶显示设备外观的一大革新。At present, in the development of liquid crystal display device technology, liquid crystal display devices with a narrow bezel design can provide a larger viewing angle in a limited space, which is a major innovation in the appearance of liquid crystal display devices.
传统的背光源，其结构主要如图1所示：由框架1’、反射片2’、 胶架8’、 LED灯条4’、 导光板3’、扩散膜5’ 、第一增光膜71’、第二增光膜72’及遮光片6’依次层叠组成。因需考虑背光与玻璃的贴合强度，所以对遮光的贴合面积有一定的要求，这样就导致，背光的边框不能太窄。如果太窄，不仅提高了组装时，遮光的贴合难度，而且还有容易造成背光周边亮线，漏光等不良。背光边框做得越窄，对遮光片6’、胶架8’等背光组件的精度要求就越高，加工难度就越大。与此同时，遮光所能贴合的面积就越小，贴合强度也越小，对组装精度的要求就越高，贴合难度也越大，不良率的增加也会越来越明显。The structure of a traditional backlight is mainly shown in Figure 1: it consists of a frame 1', a reflector 2', a plastic frame 8', an LED strip 4', a light guide plate 3', a diffusion film 5', and a first brightness enhancement film 71 ', the second brightness enhancement film 72' and the light-shielding sheet 6' are sequentially laminated. Because the bonding strength between the backlight and the glass needs to be considered, there are certain requirements for the bonding area of the shading, which leads to the fact that the frame of the backlight cannot be too narrow. If it is too narrow, it will not only increase the difficulty of shading when assembling, but also easily cause bright lines around the backlight, light leakage and other defects. The narrower the backlight frame is, the higher the precision requirements for the backlight components such as the shading sheet 6' and the glue frame 8' are, and the more difficult the processing is. At the same time, the smaller the area that can be bonded by shading, the smaller the bonding strength, the higher the requirements for assembly accuracy, the greater the difficulty of bonding, and the increase in the defect rate will become more and more obvious.

The utility model provides a backlight structure 100. The backlight structure 100 includes: a frame 1, and the frame 1 forms an accommodating space. The light plate 3, the light source 4, the first diffusion film 51, the first light enhancement film 71, and the second light enhancement film 72; a shading strip 6 is arranged above the light source 4; The diffusion film 52, whose coverage is preferably but not limited to correspond to the size of the frame 1; the second diffusion film 52 has a hemming mechanism 521, and the hemming mechanism 521 is attached to the side of the frame 1 or the back. The frame 1 is usually stamped from a metal plate, preferably but not limited to an iron frame. The reflective sheet 2 can be pasted on the frame by double-sided adhesive; the reflective sheet 2 and the light guide plate 3 can be connected by double-sided adhesive; the double-sided adhesive includes acrylic adhesive, At least one of polyurethane adhesive and epoxy resin adhesive.
如图2所示，所述光源4可以为具有数个发光二极管的电路板，如LED灯条，光源4与柔性电路设置在一起；所述光源4呈条状嵌设于所述导光板3的一侧。设置在所述光源4上方的所述遮光条6范围可略大于或等于所述光源4，用来遮住光源4。As shown in Figure 2, the light source 4 can be a circuit board with several light-emitting diodes, such as an LED light bar, and the light source 4 and the flexible circuit are arranged together; the light source 4 is embedded in the light guide plate 3 in a strip shape side. The range of the shading strip 6 arranged above the light source 4 may be slightly larger than or equal to the light source 4 to cover the light source 4 .
如图3、4所示，为背光源结构100的正面和背面，所述第二扩散膜52的装配可以使背光源结构100不像传统背光源结构需要环形遮光的装配，可以省略背光边框固无需考虑背光边框的宽和窄。第二扩散膜52的固定方式是通过双面粘胶将折边结构521贴合在所述框架1的侧边或背面。所述折边结构521可以为对称设置的两折边；也可以为三折边，还可以是四折边。所述第二扩散膜52覆盖在第二增光膜72的上方且包住所述框架1的侧边或背面，可进一步提高该背光源结构的稳定性。As shown in Figures 3 and 4, it is the front and back of the backlight structure 100. The assembly of the second diffusion film 52 can make the backlight structure 100 not require the assembly of a ring-shading light unlike the traditional backlight structure, and the backlight frame fixing can be omitted. There is no need to consider the width and narrowness of the backlight frame. The fixing method of the second diffusion film 52 is to attach the hem structure 521 to the side or the back of the frame 1 by double-sided adhesive. The folded edge structure 521 can be two folded edges arranged symmetrically; it can also be three folded edges, and it can also be four folded edges.

Moreover, the fixing method of the second diffusion film 52 does not need to consider the problems such as difficult bonding and weak adhesion caused by the too narrow frame of the rubber frame 8' and the annular light shielding 6' in the traditional backlight structure as shown in FIG. 1 . One of the functions of the existing shading sheet is to fix the diaphragm, and the second diffusion film 52 can play the same role, or even better, and at the same time, the diffusion particles on the diffusion film can atomize the light, and The assembly of the second diffusion film 52 is more convenient, so replacing the existing shading effect with the second diffusion film 52 can not only improve the yield and production efficiency of backlight structure manufacturing, but also promote large-scale production.
