Abstract: A light source assembly, a backlight module, and a display device are provided in the field of display technology. The light source assembly includes a light source and a collimator. The collimator is arranged on a side of the light source where a light-emergent surface is located. When light emitted from the light source is incident on a preset surface of the collimator, a first included angle is formed between the light and the light-emergent surface. When the light is emitted out of the preset surface, a second included angle is formed between the light and the light-emergent surface. The first included angle is less than the second included angle, and the amount of light incident on per unit area of the preset surface is greater than a preset light amount threshold.

Abstract: The present invention provides a display method and a display panel. The display panel comprises a plurality of rows of sub-pixels, the adjacent sub-pixels in the column direction having different colors and being staggered from each other by ½ of the sub-pixel in the row direction. The display method comprises: S1, generating an original image composed of a matrix of virtual pixels; S2, enabling the virtual pixels to correspond to sampling locations, wherein each sampling location corresponds to a virtual pixel; each sampling location is located between every two adjacent rows of the sub-pixels, and corresponds to a location between two sub-pixels in one row and a central location of a sub-pixel in the other row; and S3, calculating a display component of each sub-pixel in accordance with original components of corresponding colors of virtual pixels corresponding to the sub-pixel. The present invention is suitable for high resolution display.

Abstract: The present disclosure provides a backlight source adjustment method, a backlight source adjustment device and a display device. After acquiring intensity information and spectrum information of current ambient light, a color temperature corresponding to the current ambient light is determined in accordance with the spectrum information of the current ambient light, and a total current to be currently supplied to a backlight source is determined in accordance with the intensity information of the current ambient light. Brightness values of light source branches having different color ranges in the backlight source are determined in accordance with the determined color temperature corresponding to the current ambient light and the total current, and currents for the light source branches are adjusted, so as to adjust color gamut of the backlight source in accordance with the current ambient light.
