A backlight module includes a substrate and light source assemblies. The substrate has a plurality of light emitting regions, and the plurality of light emitting regions are arranged in an array. A plurality of light source assemblies are disposed in the plurality of light emitting regions in a one-to-one correspondence. Each light source assembly includes a plurality of light source members arranged in an array. Each light source member includes a light emitting unit, and a reflective film configured to split light emitted by the light emitting unit. When the reflective film is disposed, the following condition needs to be met: A proportion of light split by the reflective film towards a center of the light emitting region gradually increases in a direction from the center to an edge of the light emitting region in which the light source member is located.

Backlight module and display screen

A display apparatus includes a backlight component, a light adjusting component, a display panel, and a first polarizing film. The backlight component is configured to generate polarized light. The light adjusting component is disposed on one side of the backlight component, and is configured to deflect or not deflect polarized light generated by the backlight component. The first polarizing film is disposed between the light adjusting component and the display panel. In the display apparatus) provided in this application, when the polarized light obtained after passing through the light adjusting component passes through the first polarizing film, if a vibration direction of the polarized light is consistent with a transmission direction of the first polarizing film, the polarized light can be transmitted. If the vibration direction of the polarized light is perpendicular to the transmission direction of the first polarizing film, the polarized light cannot be transmitted.

Display apparatus and electronic device

An example backlight module, an example display, and an example mobile terminal are provided. The backlight module includes a backplane having a light reflecting surface, a light source layer disposed on the light reflecting surface, and at least one light mixing component disposed on the light source layer. The light source layer has at least one point light source, and the at least one light mixing component is in a one-to-one correspondence with the at least one point light source. Each light mixing component includes a light reflecting layer configured to reflect some light rays emitted by a corresponding point light source, and a light transmission layer configured to transmit a light ray reflected by the light reflecting layer and further reflected by the light reflecting surface. The light reflecting layer is disposed above the light source layer and is configured to reflect some light rays emitted by the corresponding point light source.
