Abstract: In a predetermined main frame, a display device exerts lighting control on a first LED in a predetermined pixel with a corrected first LED gradation value lower than a first LED gradation value according to gradation data, and exerts lighting control on a second LED included in the predetermined pixel with a second LED gradation value according to gradation data. The predetermined main frame is at least one main frame included in the plurality of main frames. In the predetermined main frame, the first LED gradation value is lower than a first reference value, the second LED gradation value is lower than a second reference value, and a rate of a steady-state period to a whole lighting period in at least one lighting period is smaller than a predetermined value of less than 50% in at least one sub-frame in which lighting control is exerted over the first LED.

Abstract: Second light emitting elements and third light emitting elements are disposed at common grid-points that are adjacent in four directions to each grid-point where a first light emitting element is disposed. The controller circuit samples input data at each grid-point to generate display data to illuminate each light emitting element; controls first light emitting element illumination based on first light emitting element color information contained in first display data, which are display data sampled at each grid-point where a first light emitting element is disposed; controls second light emitting element illumination based on second light emitting element color information contained in second display data, which are display data sampled at each grid-point where a second and third light emitting element is disposed; and controls third light emitting element illumination based on third light emitting element color information contained in the second display data.

Abstract: An amphibian motor vehicle comprises a watertight engine room formed in a lower part of a vehicle body, an air intake opening formed at a front part of the vehicle body such that the air intake opening is positioned above water level when the amphibian motor vehicle cruises on water, an air passage separated from the engine room and generally extending in a longitudinal direction of the vehicle body from the air intake opening and a radiator disposed in the air passage for air cooling a coolant flowing into the radiator from the engine.
