Specific embodiment

Preferred embodiments of the present invention are described below, those of ordinary skill in the art will be according to described below It is realized with the relevant technologies of this field, and can be more clearly understood that the innovation and bring benefit of the utility model.

As shown in Figure 1, being traditional backing structure cross-sectional view, comprising: lower frame 10, center 20, main screen 30；The main screen 30 It being set on center 20, the main screen 20 is LCD display, but not limited to this；

Buckle 11 is provided on the outside of the frame wall 12 of the lower frame 10, the center 20 is set in the corresponding position of setting buckle 10 It is equipped with block button hole 21, the block button hole 21 is through-hole, and the lower frame 10 is connected in institute by the buckle 11 and block button hole 21 of setting State center 20；Due to using the block button hole of through-hole type, and between center 20 and lower frame 10, there are gaps, cause salt fog easily from block button hole Position enters, and inside the entry of backlight of gap, and path is shorter, corrodes backing structure.

Optical film 40, light guide plate 50, LED 60, backlight FPC 70 are additionally provided between the lower frame 10 and the center 20；

The light guide plate 50 is set on lower frame 10, and the optical film 40 is set on light guide plate 50, the backlight FPC70 Be pasted on the 10 right frame wall of lower frame, 12 inside, the LED 60 is welded on the backlight FPC70, and with the light guide plate 50 are correspondingly arranged.
