Embodiment one
As shown in Figure 2-5, a kind of backlight, including metal frame 2, the side and bottom surface of the metal frame 2 are provided with some
Through hole 21；By injection in some through holes 21 in the metal frame 2, if with the integrally-formed immobilized ph gradient strip 1 of the metal frame 2,
If the immobilized ph gradient strip 1 constitutes frame-shaped construction；If the light guide plate 3 being arranged in the immobilized ph gradient strip 1；The light guide plate 3 is arranged on to enter
The light emitting source of smooth surface
The backlight offers some through holes 21 on the side and bottom surface of metal frame 2, from some through holes 21 described in
If forming immobilized ph gradient strip 1 by Shooting Technique in metal frame 2, if the composition frame-shaped construction of the immobilized ph gradient strip 1, and formed with metal frame 2
Integration, eliminates the assembly process of adhesive tape 1 and metal frame 2, saves artificial and time cost, and without assembling, the gold
Adhesive tape 1 would not also be scraped chip by category frame 2；And, the adhesive tape 1 is filled with injection molding some through holes 21 in metal frame 2,
Fastness and stability between the adhesive tape 1 and metal frame 2 is also more preferable.
If a complete glue frame is formed in injection, for some glue frame side thickness than larger backlight（Than
Such as industry or the backlight of car-mounted display module）, the glue frame of injection can produce larger stress after cooling, the glue frame
Cooling stress can be pullled metal frame 2, cause metal frame 2 to deform, therefore, for some glue frame side thickness than larger
