Abstract
(EN) Provided is an LED panel comprising a plurality of arrayed LED pixel units, each of the plurality of LED pixel units comprising: normal elements including a red LED element, a green LED element, and a blue LED element; and a low-brightness element for providing an output of a brightness lower than the lowest brightness of the normal elements.
(FR) L'invention concerne un panneau à DEL comprenant une pluralité d'unités pixels de DEL en réseau, chacune de la pluralité d'unités pixels de DEL comprenant : des éléments normaux comprenant un élément DEL rouge, un élément DEL vert et un élément DEL bleu ; et un élément de faible luminosité pour fournir un rendement d'une luminosité inférieure à la luminosité la plus basse des éléments normaux.
(JA) LEDパネルは、配列された複数のLED画素ユニットを備え、複数のLED画素ユニットの各々は、赤色LED素子、緑色LED素子及び青色LED素子を含む通常素子と、通常素子の最低輝度よりも低輝度の出力を行うための低輝度素子とを備える。
