Abstract
(EN)
Disclosed are a backlight structure, a liquid crystal display panel and an electric device. The backlight structure comprises: a backboard (4); a plurality of bonding units (5) distributed at intervals on the backboard (4); a plurality of light sources (7) fixed on the backboard (4) by means of the plurality of bonding units (5). The projected area of the contact surface between the plurality of light sources (7) and the plurality of bonding units (5) is less than or equal to the projected area of the plurality of light sources (7) on the backboard (4), which can improve the heat dissipation efficiency of the backlight structure.

L'invention concerne une structure de rétroéclairage, un écran d'affichage à cristaux liquides et un dispositif électrique. La structure de rétroéclairage comprend : un panneau arrière (4) ; une pluralité d'unités de liaison (5) réparties à intervalles sur le panneau arrière (4) ; une pluralité de sources de lumière (7) fixées sur le panneau arrière (4) au moyen de la pluralité d'unités de liaison (5). La zone projetée de la surface de contact entre la pluralité de sources de lumière (7) et la pluralité d'unités de liaison (5) est inférieure ou égale à la zone projetée de la pluralité de sources de lumière (7) sur le panneau arrière (4), ce qui peut améliorer l'efficacité de dissipation de chaleur de la structure de rétroéclairage.
