Fig. 1 is the common naked synoptic diagram of looking the 3D LCD;

Fig. 2 is a perspective exploded view of the present utility model;

Fig. 3 is a combination diagrammatic cross-section of the present utility model, only shows the state to the housing section.

Embodiment

Be illustrated in figure 2 as the bonding structure of the naked 3D of the looking LCD that the utility model embodiment provided, it mainly is made up of a housing 20, a backlight module 30, a display panel 40, an inside casing 50 and an original screen panel 60, wherein:

Described housing 20, it has a storage tank 21 that is provided with in regular turn for described backlight module 30, display panel 40, inside casing 50 and original screen panel 60, and this storage tank 21 is defined towards the trough wall surface 212 of this original screen panel 60 directions extension by these groove bottom 211 peripheries by a groove bottom 211 that reclines with described backlight module 30 and to form.

Described backlight module 30, it has second shady face 32 that first shady face 31 and that is posted by described storage tank 21 groove bottom 211 is in reverse to this first shady face 31.

Described display panel 40 is a TFT display panel, and it has second display surface 42 that first display surface 41 and that repeatedly is against described backlight module 30 second shady faces 32 is in reverse to this first display surface 41.

Described inside casing 50, it comprises an annular peripheral frame 51 and has a hollow region 52 that this inside casing 50 comprises that more first a frame face 53 and that repeatedly is against described display panel 40 second display surfaces 42 is in reverse to the second frame face 54 of this first frame face 53.
