| titleOfInvention | Display panel and display device |
| abstract | The invention discloses a display panel and a display device, comprising: the array substrate and the opposite substrate are oppositely arranged, the optical detector is positioned between the array substrate and the opposite substrate, and the transparent medium layer with a set pattern is positioned on one side of the opposite substrate, which is far away from the array substrate; the transparent dielectric layer has a refractive index greater than that of a member in contact with the transparent dielectric layer. When light is incident to the interface between the transparent medium layer and the contacted part, the incident angle of the large-angle light reflected to the transparent medium layer by the finger is larger than or equal to the critical angle of total reflection, so that the light is totally reflected; the small-angle light reflected to the transparent medium layer by the finger can be directly incident to the inside of the display panel through the area uncovered by the transparent medium layer pattern, so that the light received by the optical detector is the small-angle light reflected by the fingerprint at the corresponding position, the incidence of the large-angle light reflected by the fingerprint at other positions is avoided, and the detection sensitivity of the optical detector is favorably improved. |
