Title
(EN) LED MODULE AND LED DISPLAY DEVICE
(FR) MODULE DE DEL ET DISPOSIF D'AFFICHAGE À DEL
(ZH) 一种LED模块及LED显示装置
Abstract
(EN)
Provided are an LED module and LED display device, comprising a circuit board (10), and a red LED (20), green LED (30), and blue LED (40) arranged on the circuit board (10); at least one of the red LED (20), green LED (30), and blue LED (40) is of a quantity of more than one; the red LED (20), green LED (30), and blue LED (40) are arranged in the same row or column, and LEDs of the same color are arranged adjacently. By means of adjusting the quantity and positions of the RGB three-color LEDs in the LED module, the effect of improving the color contrast and brightness of the LED module is achieved.
(FR)
L'invention concerne un module de DEL et un dispositif d'affichage à DEL, comprenant une carte de circuit imprimé (10) ainsi qu'une DEL rouge (20), une DEL verte (30) et une DEL bleue (40) disposées sur la carte de circuit imprimé (10) ; au moins l'une de la DEL rouge (20), de la DEL verte (30) ou de la DEL bleue (40) est d'une quantité supérieure à un ; la DEL rouge (20), la DEL verte (30) et la DEL bleue (40) sont disposées dans la même rangée ou dans la même colonne, et les DEL de même couleur sont disposées de manière adjacente. Un effet d'amélioration du contraste de couleur et de la luminosité du module de DEL est obtenu grâce à l'ajustement de la quantité et des positions des DEL à trois couleurs RVB dans le module de DEL.
(ZH)
一种LED模块及LED显示装置,包括电路基板(10),以及设置在电路基板(10)上的红光LED(20)、绿光LED(30)以及蓝光LED(40),红光LED(20)、绿光LED(30)以及蓝光LED(40)中至少有一种颜色的LED数量大于1,红光LED(20)、绿光LED(30)以及蓝光LED(40)设置在同一行或同一列,且相同颜色的LED相邻设置。通过对LED模块中的RGB三色LED进行数量的调整以及位置的排列,以达到提升LED模块颜色对比度以及亮度的效果。
