Timing generator for driving LCDs

A display apparatus comprising:

• a decoder/driver for receiving a video signal, extracting a synchronization signal from said video signal and generating an image signal from said video signal;
• a timing generator for generating timing control pulses in accordance with said synchronization signal;
• and
• a display panel for writing said image signal sequentially into picture elements in accordance with said timing control pulses,
• wherein said timing generator comprises:
• a frequency adjusting unit for adjusting a frequency of said timing control pulses by a fixed external input, said frequency adjusting unit having:
• a basic pulse generating unit for generating basic pulses;
• a counter for counting said basic pulses;
• and
• a means for outputting said timing control pulse after said counter counts a predetermined number of basic pulses;
• wherein said predetermined number is equal to said fixed external input.

A method for supplying timing control pulses to a display panel, said method comprising the steps of:

• providing a display panel;
• connecting a timing generator to said display panel;
• adjusting a frequency of timing control pulses output from said timing generator by:
• generating basic pulses;
• counting said basic pulses;
• and
• after counting a predetermined number of basic pulses, outputting said timing control pulse, said predetermined number being equal to a fixed external input;
• and
• supplying said adjusted timing control pulses to said display panel.
