Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

1 is a schematic view illustrating a stereoscopic image display apparatus using a parallax barrier system.

Referring to FIG. 1, the stereoscopic image display apparatus 10 may include a video panel 13 and a barrier 11.

The barrier 11 formed by repeatedly arranging the closed mouth 11-1 as the opaque region and the opening 11-2 as the transparent region may be disposed on the front surface of the image panel 18. [ The image panel 18 is composed of a right eye corresponding pixel 13-1 shown by the right eye and a left eye corresponding pixel 13-2 shown by the left eye.

At this time, the observer can see the image displayed on the image panel 18 through the opening 11-2 of the barrier 11. The left eye 15 and right eye 14 of the observer can see the same opening 11-2, The user can see different areas of the video panel 13, respectively.

That is, the observer can see the image displayed on the pixels of the adjacent region through the transparent region 11-2 of the left eye and the right eye, so that a three-dimensional feeling can be felt. Such parallax barriers can be converted to 2D and 3D.

2 is a schematic view showing a stereoscopic image display device using a lenticular method.

In the lenticular method, different images are displayed on the left and right eyes using the refraction of light passing through the lens of the lenticular lens plate 21 on which the semicylindrical lenses 28 and 29 are arranged, And the three-dimensional feeling can be sensed by the time difference of the two.

2, a position visible through the first lens 28 in the right eye 26 is a region 23 of the display panel, and a position viewed through the second lens 29 is located in another region 25).

The position shown through the first lens 28 in the left eye 27 is one area 22 of the display panel and the position viewed through the second lens 29 is the other area 24 of the display panel. have.

That is, the positions shown in the right eye are one of the areas 23 and 25 in the display panel, and the positions shown in the left eye are the other areas 22 and 24 of the display panel, and other positions that do not overlap with each other can be seen. Accordingly, if different images having parallaxes are arranged on the display panel at the positions where the left eye is visible and the right eye, respectively, an observer can see stereoscopic images.

Figs. 3 and 4 are views schematically showing a vertical type and a tilted parallax barrier. Fig.

Referring to FIGS. 3 and 4, in the design of the lenticular lens plate and the barrier, when the openings and the openings are arranged in the vertical direction as shown in FIG. 3, the sub-pixel color values of adjacent panels periodically interfere Moire appears in the stereoscopic image.

In order to avoid this, as shown in Fig. 4, the lenticular lens plate and the barrier can be designed in a (Slanted) pattern having a constant inclination. If the lenticular is vertically designed, the same moiré phenomenon appears, so that it can be designed to have the same angle as the barrier.

On the other hand, the multi-viewpoint stereoscopic display is a method of arranging a plurality of scenes having a large number of parallaxes in a specific order on a display panel, and can be generally used from four to twelve.

FIG. 5 is a schematic view showing the seventh point of view as an example in which the tilting angle agrees with the parallax barrier of the multi-point or the point-by-point mapping pattern of the lenticular.

FIG. 5 is an example of a mapping pattern for an 8-view non-eye hardened stereoscopic display. When viewing the openings 41, 42, and 43 from the observer's eye to the left eye or one eye of the right eye, the seventh point of time from 0 to 7 is indicated as being visible. This mapping pattern will depend on the pitch of the barrier or lenticular lens plate.

In FIG. 5B, B denotes a blue sub-pixel, R denotes a red sub-pixel, and G denotes a green sub-pixel in each pixel of the display panel, And the number of the time points to be placed in the memory.

For example, if the R subpixel is 3, the R value of the image at the third time point is allocated to the corresponding subpixel. If the subpixel values at each viewpoint are not mapped to the correct positions, stereoscopic images are not implemented, and fatigue of the eyes of a person can be caused.

Accordingly, matching the designed parallax barrier or the pitch of the lenticular (i.e., the width of each stripe) with the period of each sub-pixel value of the display panel is one of the most important factors in the spectacle-free stereoscopic display.

6 is a photograph of a periodicity generated when a pattern with an incorrect pitch is displayed on a non-eye-warming stereoscopic display.

Fig. 7 is a photograph showing that the period is larger than that in Fig. 6 when the pitch is not correct, as in Fig.

Fig. 8 is a photograph showing that the pitch becomes large enough to be almost matched.

Fig. 9 is a photograph of the image of a monochromatic image with exactly the same pitch.

6 to 9, after generating a specific pattern using a computer or the like, the generated pattern may be displayed on the non-eye-tight stereoscopic display. The pattern may be a plurality of oblique lines having a predetermined interval.

Next, if the interval between the plurality of oblique lines is changed to observe the phenomenon appearing on the unshown stereoscopic display and the periodicity is observed without being observed in a single color, the interval between the oblique lines at that time is the parallax barrier or the pitch of the lenticular I can see that it is not. On the other hand, when a phenomenon appearing in a non-eye-warming stereoscopic display is observed in a single color, the interval between a plurality of oblique lines at that time can be regarded as a parallax barrier or a pitch of a lenticular.

In more detail, a pattern of a plurality of oblique lines having a predetermined interval may be displayed on the non-eye-tight stereoscopic display.

At this time, when the interval between the oblique lines is increased or decreased, the interval may be monochromatic as shown in FIG. The interval at this time can be seen as the exact value of the parallax barrier to be measured or the pitch of the lenticular.

In this case, when a straight line is displayed by a computer program, an accurate value can be obtained by programming to display an interval parameter.

That is, the parallax barrier and the lenticular pitch measurement method of the stereoscopic display apparatus and the non-eye-warming stereoscopic display according to the embodiment of the present invention exhibit a pattern of straight line slanting lines having a constant interval, It can be recognized that when the color is divided into a single color and a single color, the color becomes a correct pitch value.
