Abstract: Provided are a backlight module, a display device, a method for driving a display device, an electronic apparatus, and a computer-readable storage medium. The backlight module includes: a base substrate; multiple light emitting modules disposed on a side of the base substrate, where each of the multiple light emitting modules includes a first light emitting region, a second light emitting region and a third first light emitting region; and a light exiting layer disposed on a side of the light emitting modules facing away from the base substrate. Vertical projections of the first light emitting region, the second light emitting region and the third light emitting region on the base substrate overlap with vertical projections of a first light exiting region, a second light exiting region and a third light exiting region on the base substrate respectively. Each backlight driving module is connected to at least one light emitting module.

Abstract: Provided are a quantum dot display panel, a preparation method, and a display device. The quantum dot display panel includes a backlight module, a quantum dot color filter structure, a first reflecting layer and a second reflecting layer. The quantum dot color filter structure is positioned on a light exit side of the backlight module. The quantum dot color filter structure includes at least a red quantum dot color filter unit, a green quantum dot color filter unit and a composite quantum dot color filter unit. The first reflecting layer is arranged on a side of the quantum dot color filter structure facing away from the backlight module. The first reflecting layer covers the red quantum dot color filter unit and the green quantum dot color filter unit. The second reflecting layer is arranged on a side of the backlight module facing away from the quantum dot color filter structure.
