Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1, 2 and 3, the present embodiment provides a display device with a narrow frame, including a front cover plate 10, a back shell plate 20, a middle fixing plate 30, a display body 40 and a light guide body 50, wherein a placing groove 21 is formed on a surface of the back shell plate, a sliding groove 211 is formed on a side wall of the placing groove, an accommodating cavity is formed between the light guide body and the back shell plate, and the light guide body may be a glass light guide plate. The display body and the two side edges in the horizontal direction are frameless in the embodiment, and the front cover plates at the top and the bottom are fixedly clamped, so that the effect that the side edges are zero frames can be achieved, and a large adjustable space is provided for the size of the frame of the side edges. In other embodiments, the bottom surface and the top surface of the display body in the vertical direction are borderless, and the two sides in the horizontal direction are fixedly connected by the front cover plate and the glue. Or the display body can be fixed on four sides through the front cover plate.
The display device of this embodiment forms a cavity that has the standing groove through front shroud and back shell plate to place display body and glass light guide plate in the standing groove, it is fixed that display body and glass light guide plate carry out the adhesion through the middle part fixed plate. And the middle fixing plate is assembled with the front cover plate and the back shell plate, namely clamped and fixed in the sliding groove on the side wall of the back shell plate. Therefore, the transverse fixed width of the front cover plate is the width of the frame of the display device, and the front cover plate can be an arc-shaped plate, a right-angle cover plate or a T-shaped cover plate. Can fix the middle part fixed plate through the front shroud of difference, and the structure of the front shroud of isostructure can also improve the variety of display device outward appearance, consequently improves the flexibility of display device frame width design, and the size that satisfies the frame is narrower, can also satisfy the structural strength of display device frame simultaneously, improves the security.
