Abstract: Display panel, display apparatus and method for fingerprint recognition are provided. The display panel includes a base layer, a light-emitting layer and a light-shielding layer having at least first and second imaging pinholes. The second imaging pinhole is disposed between two adjacent first imaging pinholes. The display panel further includes a light-sensitive fingerprint sensor layer and a fingerprint recognition light source generating first light during a first time period and second light during a second time period. The first light passes through the first imaging pinholes and the second imaging pinholes do not allow the first light to pass through, and the second light passes through the second imaging pinholes and the first imaging pinholes do not allow the second light to pass through.
