Abstract

The invention discloses a display panel and a display device.The display panel comprises a first display area, a second display area, a first substrate, a first light shielding layer, a second light shielding layer, a first electrode layer, a light emitting layer and a second electrode layer; the second electrode layer is provided with a light-transmitting opening between at least part of adjacent first sub-pixels in the first display area; the first shading layer is provided with a first opening corresponding to the light-transmitting opening in the first display area, and the second shading layer is provided with a second opening corresponding to the light-transmitting opening in the first display area. According to the invention, the second light shielding layer is arranged on the basis of the first light shielding layer, so that the overall thickness of the light shielding layer is increased equivalently, the part of the second electrode layer corresponding to the first sub-pixel is prevented from being fallen off by laser, and the laser precision and the light transmittance of the first display area are improved.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] For an AMOLED (Active-matrix organic light-emitting diode) display panel, how to improve the light transmittance of the photosensitive area of ​​the display panel has always been a difficult problem. One method currently adopted is to adopt the patterned design of the cathode layer in the photosensitive area. The photosensitive area includes a pixel area and a light-transmitting area. The pixel area is used to set light-emitting pixels, and the light-transmitting area is used to transmit light. The cathode layer in the light-transmitting area can improve the transmittance of the light-transmitting area. When the infrared laser is irradiated from the back of the display panel to the photosensitive area, the film below the cathode layer has almost no absorption of the infrared laser, resulting in not ...
