Abstract: The present disclosure relates to a backlight module, a method for manufacturing the backlight module, and a display device. The backlight module includes a substrate, a plurality of LED chips, and a first film having a plurality of channels. Each channel is filled with a channel filling portion. A refractive index n1 of the first film is smaller than a refractive index of the channel filling portion is n2. The first film has a first region and second region. Channels in the first region are astigmatism holes for diverging the light having a high intensity and channels in the second region are light-converging holes for converging the light having a low intensity, thereby alleviating or eliminating the starry phenomenon.

Abstract: Embodiments of the present disclosure provides a display panel, a display device, and a display method. A density of a first pixel unit in a first display area is smaller than a density of a second pixel unit in a second display area. In the first pixel unit, a first sub-pixel row includes sub-pixels of different colors arranged along a first direction, and a second sub-pixel row includes first high-transmittance sub-pixels. A plurality of first pixel units are arranged along a second direction to form a first pixel unit column. In one of first pixel unit columns, the first sub-pixel rows and the second sub-pixel rows are alternately arranged. Two closest first sub-pixel rows are located in two adjacent first pixel unit columns and staggered from each other in the first direction.

Abstract: A display panel includes an array substrate, a protective cover, a fingerprint identification circuit, and an optical structure. The array substrate and the protective cover are disposed oppositely, where the protective cover is located at a light exiting side of the array substrate. The fingerprint identification circuit is located at a side of the array substrate facing away or toward the protective cover and is configured to receive detection light and perform a fingerprint detection according to the detection light. The optical structure is located at a side of the protective cover facing away from the array substrate and is configured to increase a reflection amount of the detection light received by the fingerprint identification circuit.
