Backlight module and display device

Abstract

The invention relates to a backlight module. The backlight module comprises a backboard and a light guide plate accommodated in the backboard, wherein the light guide plate comprises a light incidentsurface and a light emergent surface which are adjacently arranged, and a plurality of side surfaces adjacent to the light incident surface and / or the light emergent surface, at least one side surfaceis provided with a reflecting film material, and a plurality of elastic blocks which are arranged at intervals are arranged on the surface, opposite to the reflecting film material, of the backboard;a plurality of through holes in one-to-one correspondence with the elastic blocks are formed in the reflecting film material, and the orthographic projection of each elastic block on the corresponding reflecting film material is located in the corresponding through hole. The invention further relates to a display device.

Description

technical field [0001] The invention relates to the technical field of display product production, in particular to a backlight module and a display device. Background technique [0002] TVs and other display devices with blue LED-quantum dot film solutions have become more and more popular compared to normal white light liquid crystal display devices because of their high color gamut and simpler manufacturing process than OLED (Organic Light-Emitting Diode). However, in side-lit backlight displays, especially in thinner and narrow-bezel models, the border rubber (rubber block) is warped due to impacts on the reflective film and peeled off from the light guide plate, resulting in blue light leakage. White light LED display becomes more severe: when white light is leaked, the picture quality will show brightness difference, which is acceptable subjectively; but when blue light is leaked, the picture quality will show color difference, and the human eye is very sensitive to co...

However, in side-lit backlight displays, especially in thinner and narrow-bezel models, the border rubber (rubber block) is warped due to impacts on the reflective film and peeled off from the light guide plate, resulting in blue light leakage. White light LED display becomes more serious: because when white light is leaked, the picture quality will show brightness difference, which is acceptable subjectively; but when blue light is leaked, the picture quality will show color difference, and the human eye is very sensitive to color difference and contrast
