Abstract:
1. A display device having asymmetric viewing angles, comprising: a display panel including a plurality of sub-pixels arranged in a matrix form having a plurality of rows and columns; wherein each of said plurality of sub-pixels is of a different sub-pixel pitch relative to its immediate adjacent sub-pixel to form multiple sub-pixel pitches on said display panel to realize asymmetric viewing angles of the display device; and a barrier having interlaced transmissive and opaque regions disposed at one side of the display panel a distance away from the sub-pixels; wherein the sub-pixels include a set of first sub-pixels of red, green and blue colors respectively having a first sub-pixel pitch, and a set of second sub-pixels of red, green and blue colors respectively having a second sub-pixel pitch different from the first sub-pixel pitch, the first sub-pixels of the first sub-pixel pitch being alternated with the second sub-pixels of the second sub-pixel pitch along each of the rows and each of the columns, and each pair of adjacent first and second sub-pixels in each of the rows are of different colors, wherein the first sub-pixels are configured to display a first image along a first direction, and the second sub-pixels are configured to display a second image along a second direction different from the first direction, and wherein the sum of the first sub-pixel pitch and the second sub-pixel pitch is equal to twice the distance between the midpoints of one first sub-pixel and one second sub-pixel adjacent thereto.
