Abstract: Disclosed are a display method, a wrist-worn device and a computer-readable storage medium. The display method is applied to the wrist-worn device. The display method includes: emitting, via a light source, a first detection light; receiving, via a light identification unit, the second detection light formed by the first detection light and identifying the light parameter of the second detection light, wherein the light parameter of the second detection light carries the style information of the wristband; reading, via the controller, the style information and generating a screen display control signal according to the style information; and controlling, via the controller, the display unit on the device body to display a corresponding display mode according to the screen display control signal.

Abstract: A button mechanism and a wearable device including the same are disclosed. The button mechanism comprises a casing, an optical signal transmitting part and an optical signal receiving part connected to a controller are disposed in the casing; and a lever comprising a connecting part connected to the casing and a shielding part block or not block an optical signal to pass therethrough, wherein the shielding part is connected to the connecting part and the connecting part is an elastic material member that is elastically stretchable, so as to be restored the shielding part. When the shielding part is applied with a force to move to a predetermined position, the optical signal sent by the optical signal transmitting part is transmitted to the optical signal receiving part; and when the shielding part is restored, the shielding part blocks the optical signal from the optical signal transmitting part.
