Detailed Description
As shown in the figure, this embodiment comprises a bracket 5, the main body part of the bracket 5 is provided with an inner cavity with an upper end face opening, and a guide groove 10 with an upper end opening is arranged at the position, close to the end part, of a first side plate 9. The upper end face of the second side plate 8 is provided with a longer groove, the outer surface of the second side plate 8 is provided with a concave groove, and the two parts are communicated through the groove of the upper end face and jointly form a pin groove 7.
The two ends of the bracket 5 are respectively provided with a lamp shade 11 with a downward opening, the inner cavities of the side lamp shades 11 are respectively communicated with the inner cavities of the bracket 5, and the upper surface of the side lamp shade 11 is an inclined surface with a high inner side and a low outer side. There are two sets of side-firing lamps 6 located in the two side-shields 11, respectively.
The inner cavity of the bracket 5 of the embodiment is sequentially provided with a backlight plate 4, a light filter plate 3 and a display screen 2 from bottom to top. The plane shape and the dimension of the main body part of the three are consistent with the plane shape of the inner cavity of the bracket 5, so that the relative position of the main body part and the inner cavity of the bracket 5 is fixed.
The backlight 4 of this embodiment is a porous plate made of a light guiding material, and the holes are through holes perpendicular to the plane direction, i.e., the through holes are open toward the filter. The backlight plate 4 can be formed by one-time injection molding of acrylic material.
