    Abstract: The present disclosure relates to the technical file of display, in particular to a side type backlight module, a method for producing the same and a display apparatus. The backlight module comprises: a LED source; a light guide plate; a wedge-shaped light guide portion located between the LED source and the light guide plate; two reflectors having reflective faces located on a top and a bottom of the wedge-shaped light guide portion and inclined with respect to an upper surface or a lower surface of the light guide plate, for adjusting the light emitting angle of the LED source; and a silicon gel part located between the LED source and the wedge-shaped light guide portion. With the inclined reflectors arranged on the top and the bottom of the silicon gel part, the present disclosure may avoid the light leak, improve the optical efficiency and suppress the light leak and hot spots effects of the light incident end of the light guide plate.

    Abstract: A splicing-screen border weakening structure includes a transparent solid element through which a light ray is able to penetrate. The transparent solid element includes a fixing surface which is used for fixing to the border and a light-ray exiting surface which is opposite to the fixing surface, and further includes an inner area which is opposite to the border and an outer area which is opposite to an edge display area of the display screen. A first prism structure is at least arranged at a position corresponding to the inner area of the light-ray exiting surface. A light ray exits from the edge display area and enters into the outer area of the transparent solid element, and a part of the light ray is deflected by the first prism structure of the light-ray exiting surface and exits from an inner area of the light-ray exiting surface.

    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.
