Display apparatus having functions of displaying video signals as enlarged/thinned pictures |
摘要 |
A display apparatus comprises driving a circuit having: a field discriminating circuit; a copy/thinning discriminating circuit; a pulse generating circuit for generating copy clock pulse signals in a horizontal period in addition to original clock pulse signals in an operation to display an enlarged picture; a gate-clock generating circuit for generating gate-clock signals obtained as a result of superposing all of the original clock pulse signals on some of the copy clock pulse signals the number of which is equal to a difference obtained as a result of subtraction of a vertical-pixel count of a video signal from a vertical-pixel count of a display unit; and a gate driver for generating a plurality of gate driving signals at a high level for pulses of the gate clock signals with timings different from each other.
