US 6,326,981 B1 · Color display apparatus

Abstract

A color display apparatus, such as a color liquid crystal display apparatus, is composed of a multiplicity of sub-pixels each designed for displaying one of a plurality (k) of mutually different mono-colors and arranged in rows and columns so as to form pixels each with a plurality of mutually adjacent sub-pixels. The sub-pixels and pixels are so arranged that a number n given by dividing a total number of sub-pixels arranged in a row or column with a total number of pixels arranged in the row or column is set to satisfy: 1<n<k, wherein k denotes the plurality of the mono-colors displayed by the sub-pixels. As a result, the pixel pitch can be reduced to provide an increased display density and an improved display quality.

Dependent claims

A color display apparatus, comprising:

a multiplicity of sub-pixels each designed for displaying one of 3 mutually different mono-colors and arranged in β rows and α columns so as to form pixels each with 3 mutually adjacent sub-pixels,
the pixels being arranged in Y rows and X columns wherein β, α, Y and X are independently integers greater than 1;
and
a number n given by dividing a total number of sub-pixels in one of β rows with a total number of pixels in one of Y rows is substantially equal to (3Y/X)½ while satisfying the relationships:
1<n< and Y/X<n
the pixels and sub-pixels are arranged so as to include a unit of four pixels formed by three rows and four columns of sub-pixels wherein each pixel has two sub-pixels in a given row and a third pixel in an adjacent row.
