Abstract

The invention relates to a fingerprint cover plate and a fingerprint identification module including the fingerprint cover plate, and a handheld terminal. The fingerprint cover plate comprises a platebody and a color-changing identification layer arranged on one side of the plate body. A preset pattern formed on the surface of the plate by the color-changing marking layer can serve as a marking function. Further, when the illumination parameter or the temperature parameter changes, the color of the photochromic ink layer or the thermochromic ink layer in the color-changing identification layer will change correspondingly, or the photochromic ink layer will store energy or emit light, so that the preset pattern presents color and light-shade changes. When the user uses the handheld terminal, the illumination parameters and temperature parameters will change with the use of time and the switching of the environment, which will lead to the color or shade of the discolored identificationlayer also changes. Therefore, the user can experience a plurality of different appearance colors of the fingerprint identification module without replacing the handheld terminal, so that the user experience is effectively improved.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint cover, a fingerprint identification module and a handheld terminal including the fingerprint cover. Background technique [0002] With the continuous development of various electronic products, the requirements for their uniqueness, security and confidentiality are also getting higher and higher. Therefore, the fingerprint identification technology has been basically popularized and applied to various electronic products. [0003] When the fingerprint identification module is applied to handheld terminals such as mobile phones, in order to achieve consistency in appearance, the color of the fingerprint identification module usually needs to be consistent with the overall tone of the handheld terminal. At present, the color of the cover plate is mainly used to distinguish the color of the fingerprint identification module. [0004] Users always h...
