Abstract:
A luminous display unit having plural light emitting portions by using a self light emitting element reduced in light emitting luminance in accordance with a light emitting time and having differences in light emitting time in their light emitting portions, and characterized in that, when a light emitting mode in said light emitting portions is regularly determined, said light emitting time is presumed from light emitting frequencies of said light emitting portions calculated from said light emitting mode, and the initial light emitting luminances are set to be different from each other in a light emitting portion having a large light emitting frequency and a light emitting portion having a small light emitting frequency during use of said luminous display unit so as not to cause a recognizable difference in light emitting luminance between both the light emitting portions during use.
