- the boundary of the viewpoint may be reduced to provide a smooth image. This will be described in more detail with reference to FIGS. 11 and 12.
- 11 is a diagram conceptually illustrating an image sequence in an image display method according to another exemplary embodiment of the present invention.
- 12 is a diagram conceptually showing an image sequence in the image display method according to the prior art.
- n 8
- z 4 (4 basic images)
- (z1) 3 (3 input images)
- the present invention is not limited thereto. Therefore, it is a matter of course that the case where n has various values, in particular, may include all cases where n is a multiple of 2.
- the (z1) input images include a first basic image as a first image, a second basic image as a second image, and a third basic image as a third image.
- (z2) that is, one
- auxiliary images corresponding to the second image are generated as the fourth basic image.
- first to fourth compensation images are generated corresponding to the first to fourth basic images. More precisely, the first compensation image is a first image, the second compensation image is a second image, the third compensation image is a third image, and the fourth compensation image is a second image.
- the driving unit 300 After the first, second, and third compensation images corresponding to the input image and the first, second, and third compensation images corresponding to the first image are projected, the driving unit 300 includes the fourth basic image as the auxiliary image and the fourth corresponding image. Allow the secondary image to be projected. Accordingly, the first basic and compensation images (two first images), the second basic and compensation images (two second images), the third basic and compensation images (two third images), and the fourth basic and compensation images (Two second images) are projected in sequence. That is, when viewed as a whole, the image order is first, first, second, second, third, third, second, second, first, first, second, second, third, third, It becomes a 2nd, 2nd image. As a result, a large point difference does not occur. Therefore, the user does not feel the boundary between the viewpoints and smoothly recognizes the image.
- the first, second, third, fourth, fifth, sixth, seventh, and eighth images are sequentially projected at the same eight time points, and then again the first and second images.
- the second, third, fourth, fifth, sixth, seventh, and eighth images are sequentially projected.
- the first, second, third, fourth, fifth, sixth, seventh, eighth, first, second, third, fourth, fifth, sixth, seventh, and eighth images Since the projection is performed in this order, the user may feel a large difference in viewpoint at the boundary between the eighth image and the first image. Accordingly, the user may feel discomfort due to the boundary of the viewpoint.
- the z input images and the y compensation images are used so that the user does not feel the boundary between the viewpoints and smoothly recognizes the images.
- the boundary line of the light transmitting unit 110 has an oblique form.
- the present invention is not limited thereto, and as illustrated in FIG. 13, at least a portion of a boundary between the light blocking portion 124 and the light transmitting portion 114 in the parallax barrier 24 may define a boundary between the unit pixels 210. It may be formed along the diagonal direction of the display panel 100 having a step shape that follows. More specifically, in one row, the boundary line of the light transmitting unit 114 substantially coincides with the boundary line of the unit pixels 210, and in another row adjacent thereto, the boundary line of the light transmitting unit 114 corresponds to the unit pixel ( And substantially coincide with the virtual centerline of 210. According to the light emitting unit 114 having such a shape, a clear image may be realized by clearing a boundary of a multiview image.
- the present invention is not limited thereto.
- various types of light transmitting parts may be formed.
- the parallax barrier 20 may be located behind the display panel 100.
- the width of the light transmitting part 110 of the parallax barrier 20 may be larger than the width of the unit pixel.
