Abstract: A backlight module, including a back plate, and a colored light source plate, a first color conversion layer and a plurality of first optical processing layers, which are on the back plate and sequentially arranged away from the back plate; where the backlight module further comprises a second color conversion layer on at least a side, away from the back plate, of one of the plurality of first optical processing layers farthest from the back plate; an orthographic projection of the second color conversion layer on the first optical processing layer is in a peripheral edge region of the first optical processing layer; and the second color conversion layer is configured to convert monochromatic light emitted by the colored light source plate and incident into the second color conversion layer, into white light.

Abstract: A backlight module includes a light-emitting substrate, at least one chip-on-film and a backplane. The light-emitting substrate includes a signal line group and a plurality of light-emitting units, and the plurality of light-emitting units are electrically connected to the signal line group. The at least one chip-on-film is arranged on a non-light exit side of the light-emitting substrate, and electrically connected to the signal line group. The backplane is disposed on the non-light exit side of the light-emitting substrate, and the at least one chip-on-film is located between the backplane and the light-emitting substrate. The backplane is provided with a groove therein, a notch of the groove faces the light-emitting substrate, and at least portion of a chip-on-film film of the at least one chip-on-film is disposed in the groove.
