Abstract
The present disclosure discloses a micro-mirror array, and a backlight module and a display device using the same. Each reflection mirror in the micro-mirror array comprises a first axis of deflection and a second axis of deflection perpendicular to the first axis of deflection, and a deflection angle of the reflection mirror is controlled individually and continuously. The backlight module comprises a light source, a micro-mirror array and a control unit. The control unit adjusts a deflection angle of each reflection mirror in the micro-mirror array in response to a backlight control signal, so that depending on the backlight control signal, the micro-mirror array reflects light emitted from the light source evenly to an entire surface of the display screen or converges the light to one or more areas of the display screen.
