Referring to fig. 2, in some implementations, the determining whether the panel key is triggered according to the first light intensity and the second light intensity specifically includes:
analyzing the first light intensity at the current moment and the first light intensity at the previous moment to obtain a first light intensity analysis result;
analyzing the second light intensity at the current moment and the second light intensity at the previous moment to obtain a second light intensity analysis result;

Referring to fig. 2, in some implementations, the determining whether the panel key is triggered according to the first light intensity analysis result and the second light intensity analysis result specifically includes:
judging whether the first light intensity generates attenuation mutation or not according to the first light intensity analysis result;
when the first light intensity has attenuation mutation, judging whether the duration of the attenuation mutation of the first light intensity is greater than a preset time threshold value;
when the attenuation mutation duration of the first light intensity is larger than a preset time threshold, judging whether the second light intensity has attenuation mutation or not according to the second light intensity analysis result;
and when the second light intensity is attenuated and suddenly changed, judging that the panel key is triggered.
In some embodiments, the analyzing the first light intensity at the current time and the first light intensity at the previous time to obtain the first light intensity analysis result specifically includes:
comparing the magnitude of M1 with that of (1-x1) N1 to obtain a first light intensity analysis result; wherein M1 is the first light intensity at the current moment, N1 is the first light intensity at the previous moment, x1 is the first light intensity attenuation coefficient, and x1 is more than 0 and less than or equal to 100 percent;
then, the determining whether the first light intensity has attenuation mutation according to the first light intensity analysis result specifically includes:
and when M1< (1-x1) × N1, determining that the first light intensity has attenuation mutation.
In some embodiments, the analyzing the second light intensity at the current time and the second light intensity at the previous time to obtain a second light intensity analysis result specifically includes:
comparing the magnitude of M2 with that of (1-x2) N2 to obtain a second light intensity analysis result; wherein M2 is the second light intensity at the current moment, N2 is the second light intensity at the previous moment, x2 is the second light intensity attenuation coefficient, and x2 is more than 0 and less than or equal to 100 percent;

and when the duration of the abrupt attenuation change of the first light intensity is greater than a preset time threshold, and when M2< (1-x2) > N2, determining that the abrupt attenuation change of the second light intensity occurs.
In the embodiment of the present invention, the controller 3 first detects the light intensity of the first light intensity sensor 1, and determines whether the light intensity is suddenly changed: assuming that the detected light intensity is N1 when no key operation occurs at the previous time, and the light intensity detected by the first light intensity sensor 1 at the current time is M1, if M1< (1-X1) × N1 is satisfied, the light intensity is considered to have a sudden change, where X1 is a first light intensity attenuation coefficient, for example, assuming that X1 is preset to 90%, and if it is detected that the light intensity detected by the first light intensity sensor 1 at the current time is attenuated by more than 90% relative to the light intensity at the previous time, the condition M1< 10% × N1 is satisfied, and the light intensity is considered to have a sudden change.
Referring to fig. 2, in a specific implementation, individual errors may occur in the detection values of the light intensity sensors, or sudden changes in light intensity may be detected in a short time due to the flying of a bug at a key of the panel, so as to prevent false triggering of the key due to the above situation, when a sudden change in light intensity is detected, it may be further determined whether the duration of the sudden change exceeds a preset time threshold T, if the duration of the sudden change exceeds the preset time threshold T, it is determined whether the sudden change also occurs at the second light intensity sensor 2, if the sudden change also occurs at the second light intensity sensor 2, it is determined that the light intensity of the large environment has changed, for example, a user turns off a light, pulls a window curtain, and the like, there is no key triggering, and if the sudden change does not occur at the second light intensity sensor 2 at the same. In addition, the method for determining the light intensity abrupt change at the second light intensity sensor 2 is the same as that of the first light intensity sensor 1, and further description is omitted here.
In the embodiment of the present invention, the non-contact key may be implemented by setting the first light intensity attenuation coefficient x1, and the like. Illustratively, when the first light-transmitting hole 11 is shielded but not covered by the hand or finger of the user, and a part of the light can pass through the first light-transmitting hole 11, the intensity of the light detected by the first light intensity sensor 1 may also change abruptly, but a certain intensity of the light can still be detected. The closer the user's hand is to the panel keys, the weaker the detectable light intensity, and vice versa. The non-contact distance realized by the non-contact key can be determined by setting different first light intensity attenuation coefficients x 1. The sensing distance and the first light intensity attenuation coefficient x1 should satisfy the non-linear relationship shown in fig. 3, and it can be seen from fig. 3 that different sensing distances can be obtained by setting different attenuation coefficients. If the attenuation coefficient is close to 100%, namely no light is transmitted, the sensing distance is 0, namely the key triggering condition is that a user presses the key; in practical application, a reasonable attenuation coefficient is set according to practical requirements. In addition, as can be seen from fig. 3, the larger the first intensity attenuation coefficient x1, the longer the detectable non-contact distance. For example, by setting an attenuation coefficient of 80%, it is possible that a key can be triggered by a hand 5cm away from the key; setting 50% attenuation coefficient, the key can be triggered by hand 15cm away from the key. The actually set trigger transmittance ratio is adjusted and determined according to the sensing distance required by the item input, and further details are not given herein.
To sum up, in the electronic device provided in the embodiment of the present invention, the panel 10 of the housing is provided with the first light hole 11 to form the panel key, the first light intensity sensor 1 is provided corresponding to the first light hole 11, so that the light outside the panel 10 can be irradiated onto the first light intensity sensor 1 through the first light hole 11, the second light intensity sensor 2 is installed on the housing, so that the light outside the housing can be irradiated onto the second light intensity sensor 2, so that the second light intensity sensor 2 can detect the light intensity of the surrounding environment, the first light intensity sensor 1 and the second light intensity sensor 2 transmit the collected light intensity to the controller 3, when the user wants to trigger the panel key, the light of the first light hole 11 can be blocked, at this time, the first light intensity sensor 1 detects that the light intensity is suddenly weakened, and the light intensity detected by the second light intensity sensor 2 is unchanged, therefore, whether the panel key is triggered or not is judged by the controller 3 according to the light intensity collected by the first light intensity sensor 1 and the second light intensity sensor 2, the existing touch key is not needed, and the problems that the existing touch key is easily influenced by electromagnetic interference and cannot be controlled when hands are wet are avoided.
