摘要： A backlight unit (10) and a display device are provided. The backlight unit (10) comprises a light guide plate (101), and a light source (102), a first reflective film (101), and a second reflective film (104). The light source (102) includes a plurality of LEDs (1021) uniformly arranged. The first reflective film (103) is disposed correspondingly on a backlight side of a region opposite to each of the LEDs on the light guide plate (101); The second reflective film (104) includes at least one first sub-reflective film (1041), the first sub-reflective film (1041) being disposed correspondingly on a backlight side of a region opposite to a gap between two adjacent LEDs on the light guide plate (101). A reflectivity of the first reflective film is less than a reflectivity of the second reflective film, and a distance between the light guide plate (101) and the LEDs is less than a distance between an intersection of light beams emitted by two adjacent LEDs and the LEDs, and, a width of the frame of the display device can be reduced.

摘要： A backlight module, a fabricating method thereof, and a two-sided display device are provided. The backlight module includes a first transflective unit, a second transflective unit, and a bidirectional backlight source disposed between the first transflective unit and the second transflective unit. The bidirectional backlight source is configured to emit light both in a direction toward the first transflective unit and in a direction toward the second transflective unit, and is configured to transmit light from the direction of the first transflective unit and light from the direction of the second transflective unit. The first transflective unit is configured to transmit light in a first polarization direction and reflect light in a second polarization direction, the second transflective unit is configured to transmit light in the second polarization direction and reflect light in the first polarization direction, and the first polarization direction is perpendicular to the second polarization direction.
