Embodiment
Seeing also Fig. 3, is the three-dimensional decomposition texture synoptic diagram of 3 d display device first embodiment of the present invention.This 3 d display device 2 comprises an active gratings 21, a display panel 22, a back light unit 23, a glue frame 24 and a flexible circuit board 25.Wherein, this display panel 22 is passive illuminated display panels, as: display panels or Electrowetting display panel.This active gratings 21 is oppositely arranged with this display panel 22, these back light unit 23 superimposed sides that are arranged at this display panel 22 away from this active gratings 21, that is: direction from top to bottom, this active gratings 21, this display panel 22 and this back light unit 23 are cascading.This active gratings 21, this display panel 22 and this back light unit 23 correspondences are contained in this glue frame 24.This flexible circuit board 25 is electrically connected this active gratings 21 and this display panel 22 simultaneously.
This glue frame 24 comprises a bottom surface (not indicating) and end to end four sidewalls (not indicating).Wherein this four sidewall is perpendicular to this bottom surface, and is positioned at the same side of this bottom surface simultaneously, and this bottom surface cooperates this four sidewall to surround a receiving space (indicating).This active gratings 21, this display panel 22 and this back light unit 23 correspondences are contained in the receiving space of this glue frame 24.
This flexible circuit board 25 comprises a grating connecting portion 251 and a panel connecting portion 252.The branched structure that this grating connecting portion 251 and this panel connecting portion 252 are respectively this flexible circuit boards 25.These grating connecting portion 251 1 ends are electrically connected this active gratings 21.This flexible circuit board 25 provides these active gratings 21 drive signals to drive this active gratings 21 by this grating connecting portion 251.These panel connecting portion 252 1 ends are electrically connected this display panel 22.This flexible circuit board 25 provides these display panel 22 drive signals to drive this display panel 22 by this panel connecting portion 252.
Seeing also Fig. 4, is the perspective view after 3 d display device 2 assemblings shown in Figure 3.When this 3 d display device 2 of assembling, its number of assembling steps is as follows:
At first, the panel connecting portion 252 of this flexible circuit board 25 is fixed to this display panel 22 by anisotropic conductive film hot pressing, this panel connecting portion 252 is electrically connected with this display panel 22.The grating connecting portion 251 of this flexible circuit board 25 is electrically connected with this active gratings 21.
Then, this back light unit 23, this display panel 22 and this active gratings 21 are contained in the receiving space of this glue frame 24 successively, make this glue frame 24 fix this back light unit 23, this display panel 22 and this active gratings 21.So far, these 3 d display device 2 assemblings are finished.
Compared with prior art, 2 of 3 d display devices of the present invention use single flexible circuit board 25, and the grating connecting portion 251 of this flexible circuit board 25 and panel connecting portion 252 are electrically connected this active gratings 21 and this display panel 22 respectively.Owing to be connected to this flexible circuit board 25 that is of this active gratings 21 and this display panel 22, so the insecure problem of welding of grating flexible circuit board in the prior art 15 and panel flexible circuit board 16 can not occur, therefore, the reliability of 3 d display device 2 of the present invention is higher.And, among the present invention, 2 of this 3 d display devices use this flexible circuit board 25, reduced the use amount of flexible circuit board, also reduced simultaneously in the prior art to being electrically connected the welding technology that this grating flexible circuit board 15 and this panel flexible circuit board 16 design, thereby reduced the cost of this 3 d display device 2.
Seeing also Fig. 5 again, is the three-dimensional decomposition texture synoptic diagram of 3 d display device second embodiment of the present invention.The 3 d display device 3 of this second embodiment and the 3 d display device 2 of first embodiment are basic identical, its difference is: the display panel 32 of this 3 d display device 3 is active illuminating formula display panels, as: Plasmia indicating panel, organic EL display panel or el display panel.Simultaneously, this 3 d display device 3 does not have back light unit.This display panel 32 is oppositely arranged with this active gratings 31, and is contained in this glue frame 34.The light that this display panel 32 sends is by these active gratings 31 outgoing.
Compare with the 3 d display device 2 of first embodiment, do not need back light unit in this 3 d display device 3, therefore, this 3 d display device 3 is more frivolous.
Yet, it is described that the present invention is not limited to above-mentioned embodiment, can realize with other welding manners with being electrically connected also of panel connecting portion 251 of this flexible circuit board 25 with grating connecting portion 251 or this display panel 22 of this flexible circuit board 25 as this active gratings 21, as: soldering etc.; This display panel 22 can be a liquid crystal panel, also can be an electric moistening panel; The deformation design of above-mentioned 3 d display device 2 to first embodiment of the invention also is applicable to the 3 d display device 3 of second embodiment of the invention.In this 3 d display device 2, this active gratings 21 also can be arranged between this display panel 22 and this back light unit 23.
