摘要
An electronic device includes a display screen, which includes a cover glass, a transparent layer disposed under the cover glass disposed under the cover glass, and a display illumination layer disposed under the transparent layer. The electronic device further includes an optical ID sensing module disposed under the display illumination layer and configured to form an image of a fingerprint pattern or a palmprint pattern of a hand of a user. The electronic device further includes a light source disposed at an edge side of the transparent layer, and is configured to emit a light beam to be coupled into the transparent layer through the edge side. A portion of the light beam may be transmitted through the cover glass to illuminate the hand for imaging of fingerprint pattern or the palmprint pattern by the optical ID sensing module.
