Claim:
1. A lightening apparatus comprising: a plurality of light-emitting elements arranged in a matrix having “m” rows, “n” columns where “m” is an integer larger than 2 and “n” is a positive integer; at least two first reference voltage lines; “n” first drive voltage lines wherein a first one of said light-emitting elements is located at each intersection between said first reference voltage lines and said first drive voltage lines; a first reference voltage driver, connected to said first reference voltage lines and adapted to time-divisionally switch said first reference voltage lines; a first drive voltage driver, connected to said first drive voltage lines and adapted to supply first luminous drive voltages to said first drive voltage lines in synchronization with time-divisional switching of said first reference voltage lines; at least one second reference voltage line; “n” second drive voltage lines wherein a second one of said light-emitting elements is located at each intersection between said second reference voltage line and said second drive voltage lines; a second reference voltage driver connected to said second reference voltage line and adapted to switch said second reference voltage line; and a second drive voltage driver, connected to said second drive voltage lines and adapted to supply second luminous drive voltages to said second drive voltage lines in synchronization with switching of said second reference voltage line; a plurality of left-side light-emitting elements provided adjacently on a left-side of said light-emitting elements; left-side reference voltage lines; at least one left-side drive voltage line, wherein one of said left-side light-emitting elements is located at each intersection between said left-side reference voltage lines and said left-side drive voltage line; at least one left-side reference voltage driver, connected to said left-side reference voltage lines and adapted to time-divisionally switch said left-side reference voltage lines; at least one left-side drive voltage driver, connected to said left-side drive voltage line and adapted to supply left-side luminous drive voltages to said left-side drive voltage line in synchronization with time-divisional switching of said left-side reference voltage lines; a plurality of right-side light-emitting elements provided adjacently on a right-side of said light-emitting elements; right-side reference voltage lines; at least one right-side drive voltage line, wherein one of said right-side light-emitting elements is located at each intersection between said right-side reference voltage lines and said right-side drive voltage line; a right-side reference voltage driver, connected to said right-side reference voltage lines and adapted to time-divisionally switch said right-side reference voltage lines; and at least one right-side drive voltage driver, connected to said right-side drive voltage line and adapted to supply right-side luminous drive voltages to said right-side drive voltage line in synchronization with time-divisional switching of said right-side reference voltage lines.
