The present application provides a prism sheet and a display module. The prism sheet includes a base layer and a plurality of prisms arranged on the base layer. The prism sheet is divided into a middle region and edge regions. By making the vertex angles of the portions of the prisms in the middle region smaller than the vertex angles in the edge regions, it may be possible to improve the brightness of the backlight module in the display module and optimize the horizontal viewing angle of the display module.

Prism sheet and display module

The present invention provides a display device, including a display panel provided with an electromagnetic induction layer and a backlight module provided with a quantum dot film The quantum dot film contains a plurality of second-color quantum dots, a plurality of third-color quantum dots, and a plurality of magnetic particles. The electromagnetic induction layer is configured to generate a directional magnetic field to make the magnetic particles move directionally in the quantum dot film, and to make a density of the second-color quantum dots and the third-color quantum dots located in an edge area of the quantum dot film greater than a density of the second-color quantum dots and the third-color quantum dots located in a central area of the quantum dot film.

Display device

Provided is a white light emitting diode, comprising a substrate, and a blue chip, a light emitting layer and an inorganic protective layer, which are sequentially disposed on the substrate, wherein a material of the light emitting layer comprises green phosphor powder, red quantum dots and a disperse medium, and the green phosphor powder comprises &#x3b3;-AlON:Mn, Mggreen phosphor powder. The color gamut of white light emitting diode obtained by using &#x3b3;-AlON:Mn, Mggreen phosphor powder with high color gamut, narrow half width, and slow luminance decay can reach BT.2020 80% or more, which is equivalent to the use of green quantum dots. It meets the requirements of high color gamut while reducing the use of green quantum dot materials. The reliability of white light emitting diode is improved to reduce production costs and achieve environmental protection.
