And the angle is too big, is unfavorable for the input personnel to see the display content of display module 3 clearly on the contrary, and even, the display surface of display module 3 too inclines, can bring certain information on the contrary and reveal the risk.

Fig. 10 schematically shows a side view of a key structure according to a further embodiment of the invention.

According to the embodiment of the present invention, even if the polarizing film 301 is adopted in the display module 3, the input device needs to be protected from peeping by physical shielding because the polarizing effect of the polarizing film 301 in different directions is strong or weak, or the environment where the input device is located has a higher level of safety requirement. As shown in fig. 10, at least one side of the key 1 is provided with, for example, a first shutter 104. The direction in which peeping by others is to be prevented is different depending on the use environment, and the first blocking plate 104 may be disposed on the side of the key 1 opposite to the input person, or on any two or three sides except the side where the input person is located, for example. The first baffle 104 may be fixedly disposed on the key 1, or may be nested on the key 1. After the first baffle 104 is added, the safety of input personnel when inputting relevant information by using the input device can be further ensured.

Alternatively, the display component 3 may also be located inside the key 1, wherein the upper surface of the key 1 is not covered or the upper surface of the key 1 is made of a transparent material. In addition to the design of the display module 3 on the upper surface of the key 1 in the foregoing embodiment, the display module 3 may be designed to be located inside the key 1, and the technical effect of improving safety by disposing a baffle on the key in the foregoing embodiment may also be achieved. When the display module 3 is located inside the key 1, for example, the upper surface of the key 1 can be designed to be a non-shielding hollow structure or the upper surface of the key 1 is designed to be made of transparent materials such as toughened glass or organic glass, so that when the display module 3 is shielded by the side wall of the key 1, the display content of the display module 3 can be conveniently recognized by an input person. As shown in fig. 11, the display member 3 may be disposed at a position located at about the center of the key 1, on the one hand, if the position of the display member 3 is too high, it does not function to shield the display member 3 by the side wall of the key 1. On the other hand, if the position of the display component 3 is too low, the key 1 is not favorable to move downwards, and the touch feeling of the input person is affected. The display component 3 can also be arranged into an inclined plane with a display surface and a horizontal plane forming a certain angle, so that input personnel can see the content displayed by the display component 3 clearly. The specific tilt angle may refer to the angle adopted in the foregoing embodiments, and details are not described here.
