As shown in fig. 1, the present disclosure provides a key member including:
the optical fiber module comprises a light source 1, a waveguide fiber module 2 and a first sensor 3, wherein the waveguide fiber module 2 comprises a first end and a second end which are opposite, the light source 1 corresponds to the first end of the waveguide fiber module 2, so that light of the light source 1 is input into the waveguide fiber module 2, the first sensor 3 corresponds to the second end of the waveguide fiber module 2 and is used for detecting first light intensity information of the second end of the waveguide fiber module 2, and the waveguide fiber module 2 is partially or completely exposed to the outside to serve as a touch control part of the key component.
The light source 1 may be an LED light source 1, or may be another type of light source such as a halogen lamp, which is not particularly limited herein; in order to simplify the structure, when the key component is arranged on the display device, the backlight source of the display device can be used as the light source 1 of the key component, so that the situation that the light source is arranged for the key component independently can be avoided, the cost of the key component is reduced, and the structure of the key component is simplified; the waveguide fiber assembly 2 can be made of glass fiber materials so as to better realize the total reflection transmission of light rays in the waveguide fiber assembly 2; the shape of the waveguide fiber assembly 2 may be a cylindrical structure, wherein two cylindrical bottom ends may be respectively used as a first end and a second end of the waveguide fiber assembly, wherein the first end of the waveguide fiber assembly 2 may correspond to the light source 1, so that light emitted by the light source 1 may enter the waveguide fiber assembly 2 through the first end of the waveguide fiber assembly 2 for total reflection transmission, and the specific principle of total reflection transmission is as follows: when light propagates from the optically dense medium to the optically sparse medium, if the incident angle of the light is larger than the total reflection angle, the light does not reach the optically sparse medium, but forms total reflection in the optically dense medium, according to this principle, the incident angle of the light entering the waveguide fiber assembly can be set, so that the light propagates in the waveguide fiber assembly 2 in a total reflection manner, when the light propagates to the second end of the waveguide fiber assembly 2, the light can be output from the end face of the second end, and the first sensor can be arranged at a corresponding position of the second end of the waveguide fiber assembly 2, so that the first light intensity information of the second end of the waveguide fiber assembly 2 can be detected through the first sensor.
The key component realizes the working principle of the control function as follows:
when the key component is in a non-touch state, the light source 1 can input light into the waveguide fiber component 2 from the first end of the waveguide fiber component 2, the light propagates in the waveguide fiber component 2 and is output from the second end of the waveguide fiber component 2, and at this time, the first sensor 3 detects that the light intensity at the second end of the waveguide fiber component 2 is the first light intensity information.
As shown in fig. 7, when the key part is in the touch state, for example: when the human hand touches the waveguide fiber assembly 2, the total reflection angle of the contact area 22 of the waveguide fiber assembly 2 will change, so that the total reflection of light in the waveguide fiber assembly 2 is destroyed, and when the light which is originally transmitted in the waveguide fiber assembly 2 by total reflection propagates to the contact area 22, part of the light will be emitted out of the waveguide fiber assembly 2 and irradiated into the human hand, thus the light intensity in the waveguide fiber assembly 2 is reduced, and the first light intensity detected by the first sensor 3 is reduced.
In summary, since the light intensity of the second end of the waveguide fiber assembly 2 detected by the first sensor 3 is different when the key component is in touch and non-touch, whether the key component is in the touch state can be determined by the intensity of the first light intensity, so that the key function of the key component can be realized.
