Title:
DISPLAY APPARATUS
Document Type and Number:
Japanese Patent JP3843993
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize a high-reliability display apparatus at low costs by improving a method for high speed transmission of a display data signal, and by removing defects and restrictions accompanying acceleration of conventional signal transmission, relating to the display apparatus.
SOLUTION: The display apparatus is provided with a dividing means for dividing display data to be displayed on a display means to produce a multiple number N of serial signals, a means for multiplying each serial signal by a different code, a synthesis means for synthesizing the output signals of the multiplication means into serial signals less than the number N, a means for converting the signals outputted from the synthesis means into electromagnetic wave signals and transmitting them, a means for receiving the electromagnetic wave signals and demodulating them, and a restoration means for calculating a correlation with the codes from the output signals of the modulation means and thereby restoring the output signals to the display data, and drives the display means based on the signals restored by the restoration means.
