The side of the substrate 101 facing away from the light-emitting layer 102 is provided with an optical device 7. The optical device 7 is a fingerprint recognition sensor. In the process of fingerprint recognition, light emitted from the light emitting layer 102 is reflected when reaching the touch main body 10, and the generated reflected light passes through the polarizer 6 and the display substrate 1 to reach the optical device 7 under the screen. However, since the polarizer 6 has low transmittance, only a very small amount of light can reach the optical device 7, which reduces the use effect.

According to the display panel of the embodiment of the disclosure, an optical device 7 is arranged on one side of the substrate 101, which is far away from the organic electroluminescent layer 102, a color film layer 3 is arranged on one side of the organic electroluminescent layer 102, which is far away from the substrate 101, the color film layer 3 includes a plurality of color resist blocks 301 arranged at intervals and spacers 302 arranged between adjacent color resist blocks 301, and the spacers 302 arranged in the area of the color film layer 3, which corresponds to the optical device 7, are electrochromic structures 302A. On one hand, the electrochromic structure 302A can respond to an electrical signal to increase the light transmittance thereof, so that more external light can penetrate through the electrochromic structure 302A to reach the optical device 7, thereby improving the use effect of the optical device 7; on the other hand, the electrochromic structure 302A may respond to another electrical signal to reduce the transmittance thereof, so as to reduce the reflection of the external light and improve the display effect.

The optical device 7 may be a fingerprint recognition sensor, and of course, the optical device 7 may also be a distance sensor, but the disclosure is not limited thereto, and the optical device 7 may also be a camera assembly or the like. Taking the optical device 7 as an example of a fingerprint identification sensor, the working principle of the fingerprint identification sensor is as follows: through establishing the lower floor at the screen with fingerprint identification sensor, the light signal that display panel sent is gathered by fingerprint identification sensor and is obtained fingerprint information and realize discerning after finger fingerprint reflects. The optical device 7 may be attached to the substrate 101 by an optical adhesive, but the embodiment of the present disclosure is not particularly limited thereto.

The spacer 302 located in the area of the color film layer 3 corresponding to the optical device 7 is an electrochromic structure 302A. When the transmittance is increased, the electrochromic structure 302A can transmit more external light; when the transmittance is reduced, the electrochromic structure 302A can block light. The electrochromic structure 302A can be changed to a transparent state in response to an electrical signal to increase the transmittance of the electrochromic structure 302A, and of course, can be changed to a colored state in response to another electrical signal to decrease the transmittance of the electrochromic structure 302A.
