Title
(EN) LIGHT UNIT AND LIQUID CRYSTAL DISPLAY DEVICE HAVING THE SAME
(FR) UNITÉ LUMINEUSE ET DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES POURVU DE CELLE-CI
Abstract
(EN)
Provided are a light unit and a liquid crystal display (LCD) having the same. The light unit comprises a housing; at least one first printed circuit board (PCB) arranged in the housing in a first direction; at least one second PCB arranged in the housing in a direction opposite to the first direction; and light emitting diodes mounted on the first and second PCBs.
(FR)
L'invention concerne une unité lumineuse et un écran à cristaux liquides pourvu de celle-ci. L'unité lumineuse comprend un logement; au moins une première carte de circuit imprimé (PCB) disposée dans le logement dans une première direction; au moins une seconde carte de circuit imprimé (PCB) disposée dans le logement dans une direction opposée à la première direction; et des diodes électroluminescentes montées sur la première et la seconde carte de circuit imprimé (PCB).
