<p>PURPOSE:To reduce the production cost by reducing the number of segment lines to the utmost in a structure controlling the lighting of light emitting diodes of multiple types having driving currents different in magnitude. CONSTITUTION:Light emitting diodes 53-56 of multiple types having driving currents different in magnitude and current limiting resistors 69, 70 are mixedly connected to a line segment 61. The number of segment lines 58-61 can be reduced to the minimum number required.</p> |
