The invention provides a display panel and a display device. The display panel comprises an underlayer substrate which comprises a display area and a non-display area, a pixel array which is located at one side of the underlayer substrate and located in the display area, a flexible printed circuit board and a fingerprint sensor; the non-display area comprises a step bending area and a binding area, the step bending area is adjacent to the display area, the bonding area is located at the end, far away from the display area, of the step bending area; the flexible printed circuit board is bound to the binding area, and the pixel array and the fingerprint sensor are both electrically connected with the flexible printed circuit board; after the display panel is bent in the step bending area, the orthographic projection of the fingerprint sensor on the display panel in the first direction is located in the display area, wherein the first direction is the thickness direction along the part, corresponding to the display area, of the display panel. Accordingly, the purposes of decreasing the number of components of the display panel and reducing the weight of the display panel are achieved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Because fingerprints are innate and unique to each person. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, before operating the display device with the fingerprint identification function, the user only needs to touch the display device with a finger and identify the fingerprint information through the fingerprint sensor to perform authority verification, which simplifies the authority verification process. [0003] However, in the existing display panels, the pixel array used for light-emitting display and the fingerprint sensor used for fingerprint identification need to be electrically connected to their corresponding driver chips through diff...
