Abstract: The present invention provides a display panel and an electronic device. The display panel includes a backlight module, an array substrate, a liquid crystal layer, a color filter plate, a touch substrate, and a fingerprint recognition unit. The array substrate is disposed on a light-exiting side of the backlight module. The liquid crystal layer is disposed on a side of the array substrate away from the backlight module. The color filter plate is disposed on a side of the liquid crystal layer away from the array substrate. The touch substrate is disposed on a side of the color filter plate away from the liquid crystal layer. The fingerprint recognition unit is disposed on a side of the color filter plate away from the touch substrate. The display panel of the claimed invention can improve accuracy of fingerprint recognition.

Abstract: The present invention provides a backlight module. The backlight module includes a light source, an optical film, a diffusion plate, a back plate, and LED strips disposed on the back plate. The back plate forms a receiving cavity and includes at least two coupled LED strips. The light source, the diffusion plate, and the optical film are arranged in the receiving cavity. Wherein, LED lamps which are at an end of the LED strips and adjacent to a coupling position have an illuminating inner diameter on the diffusion plate, and the illuminating inner diameter is greater than an edge length to the coupling position, which improves technical problems of poor backlight mixing in backlight modules.
