  • the size of the upper diaphragm is larger than that of the lower diaphragm, which can solve the bright edge caused by the cut surface of the side edge of the diffuser plate and the lower diaphragm.
  • an adhesive tape may be provided on the side of the lower diaphragm close to the back panel 300, and the lower diaphragm may be adhered to the connecting portion 330 of the back panel 300 through the adhesive tape.
  • the tape can be made of a material with optical properties, so that the tape has certain optical properties, so that light incident on the tape from the second cavity 124 can realize light transmission, so that the optical component 400 is fixedly connected to the tape.
  • the brightness of the area of the display module 200 is uniform, so as to solve the problem of uneven brightness of the display area of the display module 200 caused by the brightness difference of the area fixedly connected with the tape in the optical component assembly 400 .
  • the color of the side of the partition wall 116 close to the optical component 400 can be set to yellow, which can solve the problem of causing the blue light transmitted by the optical component 400 to enter the upper diaphragm.
  • the problem of blue edge at the edge of the display area of the display module 200 can be set to yellow, which can solve the problem of causing the blue light transmitted by the optical component 400 to enter the upper diaphragm.
  • the display apparatus 20 in the above embodiments may also include other devices such as a battery, a camera, and the like, which will not be repeated here.

Abstract

La présente invention concerne un cadre intermédiaire (100) et un dispositif d'affichage (20). Le dispositif d'affichage (20) comprend le cadre intermédiaire(100). Le cadre intermédiaire (100) comprend un cadre (110) et une cavité d'installation (120) formée par l'encadrement du cadre (110). Le cadre (110) comprend une surface intérieure (111) située dans la cavité d'installation (120) et une surface extérieure (113) disposée à l'opposé de la surface intérieure (111). La surface intérieure (111) du cadre intermédiaire (100) est pourvue d'une couche d'absorption de lumière pour absorber la lumière. La couche d'absorption de lumière peut absorber la lumière irradiée sur la surface intérieure (111) du cadre (110), de façon à réduire la luminosité d'une région de bord d'une région d'affichage du dispositif d'affichage (20).
