Abstract

An image display device has a display pixel area having plural pixels arranged in a matrix fashion, plural signal lines for supplying display signal voltages to the pixels, and plural pixel selection lines for selecting pixels from among the pixels to be supplied with the display signal voltages. The pixel selection lines include Y-direction selection lines for selecting rows of the pixels arranged in the matrix fashion and X-direction selection lines for selecting columns of the pixels, and the image display device includes a circuit configuration in which the display signal voltages are supplied from the signal lines to only ones of the pixels each having selected simultaneously both of a corresponding one of the Y-direction selection lines and a corresponding one of the X-direction selection lines.

Claims (9)

1. An image display device comprising:

a display pixel area comprising a plurality of pixels arranged in a matrix fashion;

a plurality of signal lines for supplying display signal voltages to said plurality of pixels; and

a plurality of pixel selection lines for selecting pixels from among said plurality of pixels to be supplied with said display signal voltages,

wherein:

said plurality of pixel selection lines comprise Y-direction selection lines for selecting rows of said plurality of pixels arranged in the matrix fashion and X-direction selection lines for selecting columns of said plurality of pixels arranged in the matrix fashion; and

said image display device includes a circuit configuration in which said display signal voltages are supplied from said plurality of signal lines to only ones of said plurality of pixels each having selected simultaneously both of a corresponding one of said Y-direction selection lines and a corresponding one of said X-direction selection lines.

2. An image display according to claim 1 , further comprising a moving image write circuit and a still image write circuit, wherein said plurality of pixel selection lines and said plurality of signal lines are coupled at ends thereof to said moving image write circuit and said still image write circuit.

3. An image display according to claim 1 , further comprising a binary image signal output circuit, wherein said plurality of signal lines are coupled at ends thereof to said binary image signal output circuit.
