Abstract
(EN)
Disclosed are a direct-type backlight module and a display. The direct-type backlight module comprises: a back plate (10), an optical assembly (30), a middle frame (20) arranged on a front face of the back plate (10) and located at the periphery of the optical assembly (30), and a cooling fin (60) and a mini led lamp panel (40) both located between the back plate (10) and the optical assembly (30), wherein the cooling fin (60) is connected to the back plate (10), the mini led lamp panel is connected to the cooling fin, and the optical assembly (30) is connected to the middle frame (20) and makes contact with the mini led lamp panel (40). The mini led lamp panel (40) is used to make contact with the optical assembly (30), an OD value is zero, and light emitted by the mini led lamp panel (40) can uniformly irradiate on the optical assembly (30), so that the thickness of the direct-type backlight module is greatly reduced.

L’invention concerne un module de rétroéclairage de type direct et un affichage. Le module de rétroéclairage de type direct comprend : une plaque arrière (10), un ensemble optique (30), un cadre intermédiaire (20) disposé sur une face avant de la plaque arrière (10) et situé à la périphérie de l'ensemble optique (30), et une ailette de refroidissement (60) et un mini-panneau de lampe à DEL (40) tous deux situés entre la plaque arrière (10) et l'ensemble optique (30), l'ailette de refroidissement (60) étant reliée à la plaque arrière (10), le mini-panneau de lampe à DEL étant relié à l'ailette de refroidissement, et l'ensemble optique (30) étant relié au cadre intermédiaire (20) et entrant en contact avec le mini-panneau de lampe à DEL (40). Le mini-panneau de lampe à DEL (40) est utilisé pour entrer en contact avec l'ensemble optique (30), une valeur OD est nulle, et la lumière émise par le mini-panneau de lampe à DEL (40) peut rayonner uniformément sur l'ensemble optique (30), de telle sorte que l'épaisseur du module de rétroéclairage de type direct est fortement réduite.
