Background
Liquid crystal display devices have been widely used in various electronic products as display components of electronic devices, and backlight modules are an important component of liquid crystal display devices. The backlight module is divided into a side-type backlight module and a direct-type backlight module according to the different light source injection positions. The side-in type backlight module comprises a back plate, a rubber frame connected and matched with the edge of the back plate, a light guide plate, an optical film material group, a side-in type light source LED lamp bead and the like.
The middle rubber frame mainly plays a role in supporting each backlight assembly and panel to form a whole, can position the position of the screen in the module and the position of the backlight module in a product, and also plays a role in side edge sealing and reflecting light. Because the structure is generally complicated and thin, the material for forming the composite material is required to have good fluidity, strength and toughness. In addition, there is a need for reflectivity, for example, polycarbonate with 4% TiO2 has a very high reflection coefficient. The structural design of the rubber frame has a great influence on the efficiency of backlight. Since the frame is a carrier for various optical films, the frame is provided with grooves for placing various optical films without applying pressure thereto. When the structure is designed, not only the rationality of the structure but also the manufacturability, the easy manufacturability and the formability of the rubber frame mold are considered.
To sum up, it is difficult to see that the plastic frame has the functions of supporting the film material and positioning the pen and has the functions of sealing light and reflecting light, but the design of the plastic backlight module also has a series of problems of difficult assembly and operation, such as: 1. the rubber frame has narrow width and weak strength, is easy to have poor properties such as fracture, deformation and the like during assembly, and is not easy to position; 2. the workability is not good, and the problems that too many film materials and rubber frames are used for fixing the adhesive tape, the operation is complicated and the difficulty is large exist.
