Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 2 is the flow chart of the display packing embodiment of the three-dimensional display of Lenticular screen of the present invention, and as shown in the figure, the method comprises the steps:
Step 110, receives after the viewpoint data that will show, determines and the position relationship of Lenticular screen according to viewpoint and pixel mapping table.
Wherein, in described viewpoint and location of pixels mapping table, record angle of inclination and described edge viewpoint relative position in its place group and the corresponding relation of respective pixel ranks position on three-dimensional display of described Lenticular screen with respect to described three-dimensional display.
Described in the present embodiment, on three-dimensional display, be provided with Lenticular screen 10, as shown in Figure 3 and Figure 4, described in the present embodiment, Lenticular screen is arranged in parallel and is formed by a rule post lens 12, Lenticular screen 10 post distance in the horizontal direction, be that grating edge distance content is in the horizontal direction covered with one group of viewpoint, every group of viewpoint comprises n viewpoint, and the one or more pixels of its each viewpoint on can the display floater 11 of corresponding three-dimensional display, for showing the piece image of stereo-picture.Angle a between the normal of each post lens 12 and the vertical normal of liquid crystal panel 11 of definition Lenticular screen 10 is the inclination angle of Lenticular screen 10 with respect to display panels 11, below describes respectively for different inclinations angle:
As shown in Figure 3, when described inclination angle is 0 while spending, the bus 13 of the post lens 12 on described Lenticular screen 10 is arranged in the edge viewpoint of every group of viewpoint, and in Fig. 3, the 1st viewpoint and n viewpoint in every group of viewpoint are the edge viewpoint of keeping to the side most.
Preferably, the position of described many group viewpoints also can be set according to the position of described Lenticular screen 10, described bus 13 is arranged on the intersection of two neighboring edge viewpoints of two groups of adjacent viewpoint.For example, in Fig. 3, bus 13 can be adjusted on the intersection that is arranged in n the viewpoint of one group of viewpoint 12A and the 1st viewpoint of another group viewpoint 12B.Accordingly, bus 13 is not overlapping with the body region of each viewpoint, thereby can reduce to the full extent the impact of bus 13 on three-dimensional display effect.
As shown in Figure 4, when described inclination angle is greater than 0 while spending, the bus 13 of the post lens 12 on described Lenticular screen 10 is arranged in the edge viewpoint of every group of viewpoint, and in Fig. 4, the 1st viewpoint and the 6th viewpoint in every group of viewpoint are the edge viewpoint of keeping to the side most.
Step 120, adjusts the brightness of respective pixel according to this position relationship.
Alternatively, can only carry out luminance compensation to the brightness of pixel corresponding to the viewpoint at the most close described Lenticular screen edge.For example only luminance compensation is carried out in the brightness of the pixel to the viewpoint 1 shown in the viewpoint 1 shown in Fig. 3 and viewpoint n and Fig. 4 and viewpoint 6 correspondences, and the brightness of other pixels of uncompensation.
Alternatively, luminance compensation is carried out in the brightness of pixel that can be corresponding to the multiple viewpoints near described Lenticular screen edge, wherein, the pixel corresponding to viewpoint at the most close described Lenticular screen edge has the highest luminance compensation value, example is viewpoint 1 and viewpoint n as shown in Figure 3, and the viewpoint 1 shown in Fig. 4 and viewpoint 6; The luminance compensation value more having away from the pixel corresponding to viewpoint at described Lenticular screen edge is lower.Example as shown in Figure 3 the luminance compensation value of viewpoint 2 and viewpoint n-1 lower than the luminance compensation value of viewpoint 1 and viewpoint n but higher than the luminance compensation value of viewpoint 3 and viewpoint n-2, the like.Again example as shown in Figure 4 the luminance compensation value of viewpoint 2 and viewpoint 5 lower than the luminance compensation value of viewpoint 1 and viewpoint 6 but higher than the luminance compensation value of viewpoint 3 and viewpoint 4.
Equivalent luminance compensation is carried out in the brightness of pixel that alternatively, can be corresponding to the multiple viewpoints near described Lenticular screen edge.The example as shown in Figure 3 luminance compensation value of viewpoint 1,2, n-1 and n is identical, and the pixel that viewpoint 3～n-2 is corresponding is not carried out luminance compensation.Viewpoint 1,2,5 is identical with 6 luminance compensation value as shown in Figure 4 for example again, and the pixel of viewpoint 3 and 4 correspondences is not carried out luminance compensation.
By keep to the side the most brightness of edge viewpoint and inferior pixel corresponding to edge viewpoint of keeping to the side of common rising, can further improve the edge brightness in the same ken, to overcome better the problem of brightness disproportionation weighing apparatus.
Particularly, can carry out luminance compensation to the pixel corresponding to viewpoint at the most close described Lenticular screen edge according to formula L '=int (((L/M) ^b) * M), wherein, L represents the GTG value of the front described pixel of brightness rising, L ' represents the GTG value of the rear described pixel of brightness rising, high gray value when M represents the corresponding high-high brightness of described three-dimensional display, b represents to adjust parameter, 0.5 < b < 1, Int () represents bracket function.If adjust the excessive of parameter b, do not have the effect of brightness regulation; If adjust the too small of parameter b, can make brightness change too violent.Preferably make described adjustment parameter b=0.8.
Described in the present embodiment, method, by adjusting the brightness of the edge viewpoint in one group of viewpoint, makes the brightness in the same ken become balanced, thereby has improved the effect of stereo display.
Fig. 5 is the structural representation of the three-dimensional display embodiment of Lenticular screen of the present invention, and as shown in the figure, this three-dimensional display 10 comprises: position determination module 11 and brightness adjustment module 12, and its operation principle is described as follows:
When described three-dimensional display 10 receives after the viewpoint data that will show, by position determination module 11, for determining according to viewpoint and pixel mapping table and the position relationship of Lenticular screen, about described viewpoint and pixel mapping table, can be referring to above-mentioned related description; Then the described position relationship of being determined according to position determination module 11 by brightness adjustment module 12 is adjusted the brightness of respective pixel.Concrete adjustment mode and for example can be referring to above-mentioned related description.
Described in the present embodiment, the three-dimensional display of Lenticular screen, by adjusting the brightness of the edge viewpoint in one group of viewpoint, makes the brightness in the same ken become balanced, thereby has improved the effect of stereo display.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
