Description

[0001] The present invention relates to a three-dimensional display device and a method thereof,

The present invention relates to a three-dimensional image display apparatus and method, and more particularly, to a three-dimensional image display apparatus and method that divides a plurality of subpixels arranged in R, G, and B on a display panel into unit cells, When the light of the left eye image and the right eye image from the right eye pixel and the right eye pixel are transmitted to the observer through the parallax barrier, the binocular disparity interval of the left eye image and the right eye image observed through the parallax barrier Dimensional image display device and method for displaying a three-dimensional image such that the arrangement period of the left-eye image and the right-eye image is odd-numbered by designing the parallax barrier so as to be observed to be reduced to an odd multiple .

Generally, in the 3D image display technology, the binocular parallax is used as the biggest factor generating the stereoscopic effect in the near range, and the stereoscopic effect of the object is shown.

Such a stereoscopic image display apparatus is roughly divided into a stereoscopic stereoscopic image display apparatus and a naked-eye autostereoscopic stereoscopic image display apparatus depending on whether spectacles are worn.

However, in the case of a non-eye-tight stereoscopic image display device, the observer can directly feel the stereoscopic image only by watching the screen, so that the stereoscopic image display device Since the disadvantages can be solved, a lot of research has been carried out, and recent products are being released.

The non-eye-hardened stereoscopic image display device is largely divided into a lenticular method and a parallax-barrier method

In the lenticular system, cylindrical lenses are vertically arranged. The left and right images of the vertical cell (R, G, B) units are alternately arranged in the vertical direction (vertical interlace method) It is a method of separating left and right images by mounting a specially made refractive lens so that stereoscopic images can be seen.

In the parallax barrier method, pixels of a display panel are arranged in a left-eye pixel and a right-eye pixel in units of R, G, and B pixels (vertical interlace method), and left- A stereoscopic image is reproduced by providing a blocking substrate for each portion corresponding to the pixels between the pixels for the left eye and the right eye only in the left eye and the right eye only in the right eye.

On the other hand, the stereoscopic image display is progressing with the gradual increase in resolution. The higher the resolution, the narrower the spacing between the LCD and the parallax barrier. However, there is a problem that the interval is physically limited and can not be continuously narrowed down.

[ And a barrier (b) for shielding the light are formed alternately in a stripe shape alternately. That is, the parallax barriers 110 are arranged such that the opening portions a and the blocking portions b are alternately repeated, and the left and right eyes of the observer can see different pixels through the opening portions a, .

Here, the parallax barrier 110 according to the embodiment of the present invention is arranged such that the opening portion and the blocking portion are alternately repeated and the binocular disparity interval of the left eye image and the right eye image, which are viewed through the opening, And is designed to be viewed as an odd multiple of the binocular disparity interval of the image and the right eye image.

That is, the left eye image and the right eye image expressed from the left eye pixel L and the right eye pixel R reach the left eye and the right eye of the observer through the respective openings 1, 2, and 3 (a) It is possible to make the effect of observing with the left eye and the right eye where the interval of the parallax is reduced to an odd multiple. Therefore, the observer observing the left and right eyes with the wide binocular parallax can observe the three-dimensional image by observing the binocular parallax with the left and right eyes reduced to an odd multiple, and immediately observe the new binocular parallax in the left and right eyes It is possible to greatly reduce the burden on the eye due to the movement. In addition, it is possible to reduce the burden on the eyes that appear in the reversal of the image even when moving to the area in the regular time area to be described later.

Fig.

The light emitted from the backlight and passing through the left eye pixel L of the display panel unit 120 passes through the opening a of the parallax barrier 110, On the other hand, the light directed to the observer's right eye is blocked by the blocking portion (b) even if the light passes through the left eye pixel (L) of the display panel portion (120). The light having passed through the right eye pixel R of the display panel unit 120 among the light emitted from the backlight reaches the right eye of the observer through the opening a of the blocking substrate 110, The light directed to the left eye of the observer is blocked by the blocking portion b. As a result, light passing through the left and right eye pixels L and R of the display panel unit 120 is transmitted only to the left and right eyes of the observer, respectively. And the observer eventually recognizes three-dimensional images.

1, the parallax barrier 110 and the display panel unit 120 are spaced apart from each other by a predetermined distance g. When the distance e between the pixel i and the left and right eyes of the observer is smaller than the opening a, Since the triangle < RTI ID = 0.0 > ABD < / RTI > and ΔDFG, which are facing each other with reference to each other, resemble each other, the distance g can be calculated using the following equation (1).

Here, z represents the design distance from the observer to the display panel portion, i represents the pixel pitch of the pixel, and e represents the distance between the two eyes of the observer, that is, the interval of the binocular parallax.

)과, 관찰자로부터 디스플레이 패널부까지의 설계 거리(z)를 곱하여 산출할 수 있다.That is, the distance g between the parallax barrier 110 and the display panel 120 according to Equation 1 is obtained by dividing the pixel pitch i of the pixel by the interval e of the binocular parallax and the pixel pitch i of the pixel Divided by the sum (e + i)

And the design distance z from the observer to the display panel unit.

4, the parallax barrier 410 according to the embodiment of the present invention is arranged such that the opening portion and the blocking portion are alternately repeated and the binocular disparity distance between the left-eye image and the right- The left eye image and the right eye image, which are observed at intervals, are reduced by an odd multiple of the binocular disparity interval.

In other words, the observer can observe that the interval (E) of the original binocular parallax is decreased by an odd multiple.

Hereinafter, the embodiment in which the left eye and right eye of the binocular disparity interval E 'reduced by a factor of three are observed through the opening (a) will be described in detail.

Therefore, the repetition period of the left eye image and the right eye image is set to be three times larger in the left eye pixel L and the right eye pixel R, respectively, corresponding to the area of the display panel unit 120 that the observer observes through the opening a It is possible to obtain the same effect as that of displaying.

4, the parallax barriers 410 are arranged in such a manner that, in the case of the left and right eyes of the observer having the interval g 'of binocular parallaxes reduced to an odd multiple, The right eye observes the left eye image displayed on the left eye pixel L of the display panel unit 120 and the right eye observes the right eye image displayed on the right eye pixel R and the right eye observes the left eye image, The repetition period of the opening portion and the blocking portion is arranged in an odd multiple so that the repetition period of the regular time and the repetition period of the repetition period is repeated odd times for the left eye observing the image.

That is, when the cubic barrier 410 is implemented by, for example, a liquid crystal panel and displays a cubic image, some liquid crystals are driven for each position to block light in a stripe form, The portion in which the liquid crystal is not rotated acts as the opening portion a and the portion in which the liquid crystal is rotated acts as the blocking portion b by displaying black so that the odd and even repetition periods are repeated odd times, The opening portion a and the blocking portion b arranged in a line are turned on or off.

The parallax barriers 410 then turn on or off the aperture portions a and b so that the left eye image and the right eye image exposed from the display panel portion 120 are transmitted S530).

That is, the parallax barriers 410 drive some of the liquid crystals by position according to a predetermined control signal corresponding to the three-dimensional image, with respect to the alternately arranged openings a and b, And the role of the unactivated opening portion a and the blocking portion b rotated by the liquid crystal is implemented by the ON or OFF operation.
