Abstract
(EN) Disclosed are a backlight module and a display device. The backlight module comprises a lamp panel, a backlight lamp and a driving circuit; in the backlight lamps driven by each driving unit, at most two backlight lamps are arranged continuously and adjacent to each other in the same row or in the same column, and these backlight lamps do not form a square-shaped structure. The connecting wires between all the backlight lamps are arranged in the same layer on the same lamp panel.
(FR) L'invention concerne un module de rétroéclairage et un dispositif d'affichage. Le module de rétroéclairage comprend un panneau de lampe, une lampe de rétroéclairage et un circuit de pilotage ; dans les lampes de rétroéclairage pilotées par chaque unité de pilotage, au plus deux lampes de rétroéclairage sont disposées en continu et adjacentes l'une à l'autre dans la même rangée ou dans la même colonne, et ces lampes de rétroéclairage ne forment pas de structure carrée. Les fils de connexion entre toutes les lampes de rétroéclairage sont disposés dans la même couche sur le même panneau de lampe.
(ZH) 公开一种背光模组及显示装置,所述背光模组包括灯板、背光灯土以及驱动电路;在每一驱动单元所驱动的背光灯中,在同一行或者同一列,至多具有两个背光灯相邻连续排列,且这些背光灯不具有成"口"状的结构;在同一灯板上,所有的背光灯之间的连接线同层设置。
