Abstract

A method for reducing a moire fringe includes calculating a moire fringe width for each of different angles between a microlens array and pixels of a display screen. The method includes determining, to be a final inclination angle between the microlens array and the pixels of the display screen, one of the different inclination angles that corresponds to a minimum width among the calculated moire fringe widths.

First claim

What is claimed is:

1 . A method of reducing a moire fringe, comprising:
calculating a moire fringe width for each of different inclination angles between a microlens array and pixels of a display screen; and determining, to be a final inclination angle between the microlens array and the pixels of the display screen, one of the different inclination angles that corresponds to a minimum width among the calculated moire fringe widths.

2 . The method of claim 1 , wherein the calculating of the moire fringe width comprises:
calculating the moire fringe width based on at least one of different intervals between the pixels of the display screen and different widths of a unit microlens of the microlens array.

3 . The method of claim 2 , wherein, if the unit microlens has a hexagonal shape, the different widths of the unit microlens comprise at least one of a horizontal width of the unit microlens, a vertical width of the unit microlens, and a diagonal width of the unit microlens.

4 . The method of claim 2 , wherein, if the unit microlens has a quadrangular shape, the different widths of the unit microlens comprise at least one of a horizontal width of the unit microlens and a diagonal width of the unit microlens.

5 . The method of claim 1 , wherein the calculating of the moire fringe width comprises:
calculating the moire fringe width based on a width of a unit microlens of the microlens array.

6 . The method of claim 5 , wherein the width of the unit microlens is determined based on at least one of a preset user viewing distance and a distance between the display screen and the microlens array.

7 . The method of claim 1 , wherein the different inclination angles between the microlens array and the pixels of the display screen comprise at least one of i) an inclination angle formed between the microlens array and a vertical interval between the pixels, and ii) an inclination angle formed between the microlens array and a horizontal interval between the pixels.

8 . The method of claim 1 , wherein the determining of the final inclination angle between the microlens array and the pixels of the display screen comprises:
determining a value combination by matching the inclination angle to an interval between the pixels; and determining a graph of the value combination and the moire fringe width by calculating the moire fringe width based on the value combination.

9 . An apparatus for reducing a moire fringe, comprising:
a moire fringe width calculator configured to calculate a moire fringe width for each of different inclination angles between a microlens array and pixels of a display screen; and an inclination angle determiner configured to determine, to be a final inclination angle between the microlens array and the pixels of the display screen, one of the different inclination angles that corresponds to a minimum width among the calculated moire fringe widths.

10 . The apparatus of claim 9 , wherein the moire fringe width calculator is configured to calculate the moire fringe width based on at least one of different intervals between the pixels of the display array and different widths of a unit microlens of the microlens array.

11 . The apparatus of claim 9 , wherein the moire fringe width calculator is configured to calculate the moire fringe width based on a width of a unit microlens of the microlens array.

12 . The apparatus of claim 11 , wherein the width of the unit microlens is determined based on at least one of a preset user viewing distance, a distance between the display screen and the microlens array.

13 . The apparatus of claim 9 , wherein the different inclination angles between the microlens array and the pixels of the display screen comprise at least one of i) an inclination angle formed between the microlens array and a vertical interval between the pixels, and ii) an inclination angle formed between the microlens array and a horizontal interval between the pixels.

14 . The apparatus of claim 9 , further comprising:
the display screen.

15 . The apparatus of claim 14 , wherein unit microlenses of the microlens array have a hexagonal shape.

16 . A non-transitory computer-readable medium comprising program code that, when executed by a processor, causes the processor to perform the method of claim 1 .
