Description

Technical Field

[0001] The utility model relates to the technical field of display equipment, and in particular to a reflective film installation structure and a display equipment. Background Art

[0002] Display devices usually include display panels, and the types of display panels include OLED display panels and liquid crystal display panel lights. Liquid crystal display panels are divided into edge-entry panels and direct-down panels according to the position of their backlight sources. The edge-entry type places the backlight source on the side of the display screen, and the linear light source forms a surface light source through the light guide plate; while the direct-down type has the backlight source under the display screen, and the matrix point light source forms a uniform surface light source through the diffuser plate. At present, most liquid crystal display panels use direct-down panels. Since there is a certain light mixing distance between the light-emitting surface and the diffuser plate of the direct-down panel, the diffuser plate is prone to deformation and collapse, so a support frame needs to be placed to support the diffuser plate.

[0003] Currently, the support frame of the direct-down panel is fixed on the back plate, and the reflective film is fixed on the back plate, which causes the reflective film to easily warp and deform after mechanical vibration and temperature changes, thereby shortening the distance between the reflective film and the diffuser plate, causing dark shadows to appear on the display screen.
