Respectively the display performance of the 3 d display device provided in embodiment 1 and embodiment 2 is characterized, characteristic manner is as follows: light backlight module, when display panels display is through the artwork master of special processing, if be A with display panels centre distance 300mm place, CCD gathers route and is parallel to display panels, progressively luminous energy is gathered, the energy that this energy receives as left eye to 200mm place CCD on the right of A from from A left side 200mm; When display panels display adopts said method to gather luminous energy, the energy that this energy receives as right eye through the Bai Heitu of special processing, CCD.The luminous energy data collected twice are placed in same form respectively, twice luminous energy that co-located obtains is the gross energy that this position receives, the luminous energy collected twice and gross energy are all divided by the maximal value of gross energy, and gross energy maximal value is set to 1, obtain energy homogeneity scatter chart.
Characterization result: as shown in Figure 8, energy homogeneity distribution curve during perpendicular screen as shown in Figure 9 for the energy homogeneity distribution curve of the 3 d display device that embodiment 1 provides when horizontal screen; As shown in Figure 10, energy homogeneity distribution curve during perpendicular screen as shown in figure 11 (horizontal screen herein and perpendicular screen are comparatively speaking) for the energy homogeneity distribution curve of the 3 d display device that embodiment 2 provides when horizontal screen.Wherein, in figure, horizontal ordinate is the position (unit be mm) of receiving plane from A place, and ordinate is the homogeneity unit of energy, and curve L represents the energy that left eye receives, and curve R represents the energy that right eye receives, and curve T represents the gross energy received.
As we know from the figure, the curve of gross energy is comparatively level and smooth, meets normal distribution, can find out the 3D display effect that the transverse and longitudinal of 3 d display device is two-way and energy homogeneity all relatively good.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
3D provided by the invention shows in film, and the first relative optical surface and the second optical surface of substrate layer are provided with the first structural sheet and the second structural sheet respectively.The first post mirror layer wherein in the first structural sheet, the axial bearing of trend orthogonal with the axial bearing of trend of the second post mirror unit of the second post mirror layer in the second structural sheet (namely axial bearing of trend is mutually vertical) of its first post mirror unit.This just can make 3D show film to have 3D effect in transverse and longitudinal both direction.Simultaneously, in this first structural sheet except comprising the first post mirror layer, in the first post mirror layer away from the surface of the first optical surface being also provided with refractive index first packed layer different from it, the surface that first packed layer contacts with the first post mirror layer is the convex-concave surface of fitting with the first post mirror layer, and the first packed layer is flat surface away from the surface of the first post mirror layer.Such setting can make two-layer post mirror layer have good post mirror effect respectively when transverse and longitudinal is placed, and making 3D show film no matter when laterally placing or longitudinal direction is placed, all having good 3D effect.In a word, this 3D is shown film and is fitted on display panels, no matter screen is laterally placed or vertically placement, all can obtain good 3D effect, can satisfy the demands of consumers to a greater extent.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
