The invention provides a fingerprint recognition device and a manufacturing method thereof, which include a light-transmitting cover plate, a first light-shielding layer, a pattern layer and a fingerprint recognizer. The transparent cover has an inner surface. The inner surface has a first area and a second area. The first area is adjacent to the second area. The first light-shielding layer is arranged on the first area of the inner surface. The first light-shielding layer has a first bottom surface opposite to the inner surface. The pattern layer is disposed on the second area of the inner surface. The color of the pattern layer is different from that of the first light-shielding layer. The pattern layer has a second bottom surface opposite to one of the inner surfaces. The maximum step difference between the first bottom surface and the second bottom surface is less than or equal to 6 microns. At least part of the first light-shielding layer and the pattern layer are located between the fingerprint reader and the transparent cover. In this way, the influence of the light-shielding layer and the pattern layer on the sensitivity of the fingerprint reader is reduced, and the fingerprint recognition sensitivity is improved.
Description
technical field [0001] The invention relates to an electronic device, and in particular to a fingerprint recognition device and a manufacturing method thereof. Background technique [0002] Since the fingerprint identification technology can play a good role in anti-theft and personal privacy protection, it has been gradually applied to mobile devices in recent years to prevent the mobile device from being stolen. Specifically, such mobile devices include covers, fingerprint readers, and touch display devices. The touch display device is arranged in the central area of the inner surface of the cover for user operation and information display. The fingerprint recognizer is arranged on the peripheral area of the inner surface of the cover to identify the user's fingerprint. [0003] In order to shield the peripheral wires of the touch display device, a light-shielding layer is provided on the peripheral area of the inner surface of the cover plate. In addition, in ord...
