Camera cover plate and camera

Abstract

The present invention discloses a camera cover plate and a camera. The camera cover plate comprises an indium tin oxide layer and two conductive layers; the indium tin oxide layer is arranged in a non-image pick-up area of the camera cover plate; and the two conductive layers are arranged in the non-image pick-up area and are both communicated with the indium tin oxide layer. When the camera cover plate is used, a direct-current voltage is applied between the two conductive layers; since the conductive layers are communicated with the indium tin oxide layer, the indium tin oxide layer has an electrical conductivity characteristic and an optical transparency characteristic, after the voltage is applied, the indium tin oxide layer will be heated, and the temperature of the camera cover plate will rise, and therefore, an anti-fog effect can be realized, and the overall appearance of the camera will not be affected; and the indium tin oxide layer avoids an image pick-up area, and therefore, the light transmission performance of the camera cover plate will not be affected. Therefore, the light transmission performance of the camera cover plate provided by the present invention can be ensured, the camera cover plate can realize the anti-fog effect, the overall appearance of the camera will not be affected, and problems in the field at present can be solved.

Description

technical field [0001] The invention relates to the field of anti-fog, and more specifically, to a camera cover plate and a camera. Background technique [0002] The camera is the main component for smart devices to collect external information, so it is particularly important to keep a clear shooting effect at all times. However, in actual use, especially when the ambient temperature changes, the shooting effect is not satisfactory; for example, when the camera changes from a low-temperature environment to a relatively high-temperature environment, the camera cover will be fogged, which directly affects the shooting effect. [0003] In the prior art, for the phenomenon of fogging on the camera cover, it is mainly avoided by adding an anti-fog layer, that is, spraying a hydrophilic film on the camera cover; when fogging occurs, the fog beads will be absorbed by the hydrophilic film, So as to achieve the anti-fog effect. Although the hydrophilic film can play the role of an...

AI Technical Summary

Problems solved by technology

Although the hydrophilic film can play the role of anti-fog, the existence of the film layer seriously affects the light transmission of the camera cover, which not only affects the shooting effect, but also reduces the aesthetics of the camera; moreover, the water absorption capacity of the hydrophilic film is limited, When it reaches saturation, it loses the anti-fog effect and the use effect is not good
