Abstract
Disclosed herein is a display panel, comprising: a support; a first layer comprising a light emitter, a first region and a second region; a second layer sandwiched between the first layer and the support; wherein the first region and the second region allow light scattered by an object (e.g., a person's finger) to transmit therethrough; wherein the second layer allows light transmitted through the first region to reach the support and comprises a light-blocking layer configured to attenuate light transmitted through the second region.
