Description

Display panel and display device Technical Field The application belongs to the technical field of display, and particularly relates to a display panel and a display device. Background The full-face screen has become a big trend of display devices such as mobile phones, and in order to increase the screen ratio as much as possible, the optical modules such as the front camera module, the front fingerprint recognition module, the infrared sensor and the like are placed at the inner side of the display area as much as possible. When the optical modules are disposed inside the display area, the display area corresponding to the optical module generally needs a large light transmittance so that light can enter the optical module.
