Abstract
(EN)
Disclosed is a display device in which design properties have been improved by eliminating flicker when the display level is changed over. A microcomputer (5) causes primary LEDs (23 and 24), which are the first and second LEDs from the right edge of primary LEDs (21 to 24) emitting light, to emit light with decreasing brightness going toward the right edge. Furthermore, the microcomputer (5) causes emission of light from LEDs from a secondary LED (77) which is disposed at the right edge of secondary LEDs (71 to 77), up to a secondary LED (73) which is disposed at a position overlapping the primary LEDs (23 and 24) emitting light with decreasing brightness going toward the right edge; and also causes secondary LEDs (73 and 74), which are the first and second LEDs from the left edge of the secondary LEDs (73 to 77) emitting light, to emit light with decreasing brightness going toward the left edge.

La présente invention concerne un dispositif d'affichage dans lequel des propriétés de conception ont été améliorées par l'élimination de papillotement lors du changement du niveau d'affichage. Un micro-ordinateur (5) entraîne l'émission de lumière avec une luminosité décroissante en direction du bord droit par des diodes électroluminescentes primaires (23 et 24), qui sont les première et seconde diodes électroluminescentes à partir du bord droit de diodes électroluminescentes primaires (21 à 24) émettant la lumière. En outre, le micro-ordinateur (5) entraîne une émission de lumière provenant des diodes électroluminescentes depuis une diode électroluminescente secondaire (77) qui est disposée au bord droit de diodes électroluminescentes secondaires (71 à 77), jusqu'à une diode secondaire (73) qui est disposée à une position recouvrant les diodes électroluminescentes (23 et 24) émettant de la lumière avec une luminosité décroissante en direction du bord droit ; et entraîne également l'émission de lumière avec une luminosité décroissante en direction du bord gauche par des diodes secondaires (73 et 74) qui sont les première et seconde diodes électroluminescentes depuis le bord gauche des diodes électroluminescentes secondaires (73 à 77) émettant de la lumière.
