In another embodiment, the first side portion 210 may determine first frequency information according to the current frame, and then control the first light source 410 to emit the first light according to the first frequency information. For example, when the current frame displayed on the display screen 100 is a music playing frame, the first side portion 210 confirms that the display device 1000 is playing music at this time according to the current frame, and determines the amplitude and fluctuation of the music as the first frequency information, and the first light source 410 emits the first light according to the amplitude and fluctuation of the music, so that the color of the outer frame 200 (at least the first side portion 210) changes color along with the amplitude and fluctuation of the music when playing the music.
According to the display device, the outer frame surrounds the periphery of the display screen, and the outer frame is in communication connection with the display screen. When the display screen displays the current picture, the first side part of the outer frame controls the first light source arranged in the outer frame to emit first light rays according to the current picture, the first light rays enter the first light guide piece and then form a surface light source through the conduction of the first light guide piece, and the surface light source is matched with the current picture due to the fact that the first light rays are matched with the current picture, and therefore the light emitting state of the first side part is matched with the current picture. The invention controls the light-emitting state of the outer frame according to the current picture displayed by the display screen, so that the display device has better visual effect and improves the user experience.
