Abstract: A display device, a backlight module and a manufacturing method of a backlight module are provided. The backlight module may include a substrate, a backlight source arranged on the substrate, and a silicone film coated on a light emitting surface of the backlight source. A cross-section of the silicone film along a direction substantially perpendicular to the substrate is an arc to diffuse light emitted by the backlight source. By coating the surface of the backlight source with an arc silicone film, the light angle of the backlight source could be increased, so as to achieve the goal of mixing light with a smaller mixing light distance, which could reduce the thickness of backlight module.

Abstract: The present disclosure relates to a driving substrate, a manufacturing method, and a micro-LED array substrate light-emitting backlight module. The driving substrate includes a first metal layer, a first high-reflection layer, and a second metal layer stacked in a top-down sequence. The driving substrate, the manufacturing method, and the micro-LED array light emitting backlight module of the present disclosure solve the loss of reflectivity issue caused by the edge forbidden area of the electrode welding pad edge forbidden region. At the same time, the limited reflectivity of traditional coated high-reflective layers (such as white oil) may also be enhanced.

Abstract: The invention provides a luminance adjustment method and apparatus for RGBW LCD, which uses first and second EOTFs to generate a grayscale luminance lookup table for RGBW LCD, and makes the grayscale-luminance relation in lookup table corresponding to the first EOTF within the grayscale interval between 0 and grayscale threshold; the grayscale-luminance relation in lookup table corresponding to the second EOTF within the grayscale interval between grayscale threshold and 255; the curve slope of the second EOTF greater than the curve slope of the first EOTF within the interval between second luminance threshold and maximum luminance value. By adopting different EOTFs for low and high grayscale intervals, the method considers the poor dark state characteristics of LCD and characteristics of RGBW LCD having higher maximum luminance, and improves the display capability of RGBW LCD in details of high grayscale images.
