    Abstract: The present disclosure discloses an optical film, a backlight module and a display device for a backlight module, and relates to a liquid crystal panel display technology field. The backlight module including: a light source emitting at least a first light; the optical film includes a light converting material which receives the first light and converts it into at least a second light exit such that the light emitting angle of the backlight module is greater than 120 degrees. In the above-described manner, the present disclosure enables the backlighting angle of the backlight module to be greater than 120 degrees, and the display device having the backlight module can be brought to a wide viewing angle effect.

    Abstract: A display device, an optical film and a manufacturing equipment thereof are provided. The optical film includes an optical layer. The optical layer includes: a first light-transmissive portion having mutually parallel light incident surface and light exit surface, and second light-transmissive portions distributed in the first light-transmissive portion. The first light-transmissive portion and the second light-transmissive portions have different refractive indexes. A contact surface of each of the second light-transmissive portions with the first light-transmissive portion includes an inclined surface neither parallel nor perpendicular to the light incident surface of the first light-transmissive portion, and at least a part of light rays perpendicularly incident from the light incident surface does not strike on the inclined surface and exits from the light exit surface. By the above solution, the invention can reduce image blurriness while enlarging viewing angle.

    Abstract: The invention provides an optical film assembly, a backlight module, and a display device. The backlight module includes a light source emitting at least a first light, a first optical film, and a second optical film laminated to the first optical film, wherein the first optical film includes a base film and a functional layer stacking up to the base film, the functional layer is a diffusion film, a brightness enhancement film, a reflection film, or a prism film, the second optical film is a light conversion layer, the light conversion layer receives the first light and converts the first light to a second light to emit, such that a light emission angle of the backlight module matches a requirement of wide viewing angle. The invention could broaden the light emitting angle of the backlight module to make the display device with the backlight module achieve wide viewing angle.

    Abstract: The disclosure provides a micro light-emitting diode display panel. The array substrate is arranged with a plurality of pixels in an array. Each of the pixels at least includes a subpixel of three colors. Each of the subpixels is disposed with at least one μLED chip corresponding to color of the subpixel. Bin levels of the μLED chips of the subpixels with the same color in two adjacent pixels are different and a difference of peak wavelengths >2 nm. The disclosure further provides a manufacturing method, the μLED chips with the corresponding color in the subpixel of the array substrate are transfer printed from the transfer printing plate to corresponding subpixels. The color and the bin level of the μLED chips in each transfer printing are identical. Bin levels of the μLED chips in the sub-pixels with the same color in two adjacent pixels are different.
