MATRIX DRIVING CIRCUIT USING OUTPUT DEVIATION CONTROL

摘要

A matrix driving circuit using output deviation control is provided to change the output per a divided surface and perform on-off control every fixed time. An X axis(10) is set up in an X axis direction of a light source. A Y-axis(20) is set up in a Y axis direction of the light source. A division surface(30) is divided in the light source in the X and Y directions. Switch units are respectively arranged as many as the division number. An X axis driving power supply and a Y axis driving power supply(25) are connected to the switch unit. The switch unit turns on/off the output of a driving circuit or each driving circuit unit to perform a scanning function.
