LIGHT CONTROL DEVICE OF TELLTALE |
摘要 |
PROBLEM TO BE SOLVED: To provide a light control device of a telltale capable of expanding luminance resolution even in an environment where the minimum pulse width is fixed due to the constraint of the equipment. SOLUTION: This is the light control device of the telltale in which the luminance of a light-emitting element of the telltale displaying the information by selectively lighting a plurality of light-emitting elements is adjusted by changing duty-cycle of the pulse signal. The luminance is determined by combining the pulse width control and periodic control of the pulse signal. COPYRIGHT: (C)2005,JPO&NCIPI
