Abstract

PURPOSE:To display even any intermediate value of a shutter speed by segments, by using an LED display plate of monolithic structure which has the same patterns and provides two-digit display. CONSTITUTION:A display platee A which has segments (a)-(g), and (h)-(n) forming the same patterns and provides two-digit display and another display plate B having an inverted patterns are arranged laterally to obtain hybrid constitution, thereby performing four digit display of numbers. Those display plates A and B are each composed of a monolithic substrate which performs two-digit number display. Then, common electrode pins E1 and E2 are alternated to employ a time-division lighting system, and intermdiate-value display is performed by the said segment without specially adding more LED display plates for the display.
