Embodiment Construction

[0027] The present invention is described more fully hereinafter with reference to the accompanying drawings that illustrate various embodiments of the invention. However, this invention may be embodied in many different ways and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of pixels and pixel arrangements may be exaggerated for clarity. The same reference numerals in the figures denote the same elements.

[0028] It should be understood that the term "basic colors" refers to red, green, blue and white, but white may be replaced by one of yellow, cyan and magenta. A pixel generally includes sub-pixels of basic colors, however, for the convenience of description of the present invention, it will be assumed that red, green, blue, and white sub-pixels...

Abstract

The present invention provides an automatic three-dimensional (3D) display device comprising: a display panel comprising arrays provided with basic pixels of four basic colors, and a columnar mirror device disposed above the display panel. The columnar mirror device array comprises a plurality of columnar mirror members extending in parallel to an inclined line, and an inclination angle of the inclined line relative to the rows of th pixels is tan-1 (a / mb), wherein, m represents the number viewpoints at adjacent lines before the inclination line appears, and a and b represent the vertical and horizontal length of each pixel. When n is 0 or a natural number, the number of viewpoints is 2m (2n +1), pixels corresponding to the given viewpoints repeat every m lines in each the columnar mirror member, the number of parallel lines extending in parallel to the inclined line through the pixels in the columnar mirror member is equal to the number of the viewpoints, and each of the parallel lines depends on the repeated basic pixels.

Description

technical field [0001] Exemplary embodiments of the present invention relate to display devices having an autostereoscopic 3D or 2D / 3D switchable pixel arrangement, and more particularly, to an autostereoscopic 3D or 2D / 3D switchable pixel arrangement capable of compensating for brightness reduction. A display device in which the pixels of a display are arranged. Background technique [0002] 3D (Three-Dimensional) display technologies are classified into stereoscopic display technologies that require a viewer to wear special glasses such as shutter glasses to view a 3D image, and autostereoscopic display technologies that do not require special glasses. The stereoscopic display technology requires glasses that may include shutter glasses having liquid crystals for left and right eyes respectively that alternately transmit and block light at a predetermined period, and means for driving the shutter glasses. That is, images for the left and right eyes are provided separately...
