Problems solved by technology
The current popular in-screen fingerprint recognition system is to install the fingerprint recognition module under the organic light-emitting diode (OLED) display panel, and attach a buffer member to the back of the fingerprint recognition module to improve the impact resistance. In the case of a point impact, due to deformation, tensile stress will be generated at the interface between the OLED display panel and the fingerprint recognition module, the photosensitive sensor, etc., resulting in the separation of the fingerprint recognition module and the display panel, and the failure of the photosensitive sensor system.

Embodiment Construction
[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0032] Due to the uniqueness and invariance of each person's fingerprint, the technology of using fingerprint as identification has developed rapidly in recent years. For example, in the field of mobile phones, as more and more people have requirements for narrow borders and full screens of mobile phones, optical fingerprint recognition technology has become more and more widely used. The basic principle of optical fingerprint recognition technology is: the light emitted by the light source in the display panel is...

Embodiments of the invention disclose a display panel and a display apparatus. The display panel comprises a display substrate, a fingerprint identification module located on one side, deviating fromthe light emergence surface of the display panel, of the display substrate and comprising at least one fingerprint identification unit, a light source, a first protective layer arranged on one side, deviating from the light emergence surface, of the display substrate and provided with at least one through hole, and a second protective layer surrounding the fingerprint identification unit and embedded between the display substrate and the fingerprint identification module, wherein the fingerprint identification unit is used for performing fingerprint identification according to fingerprint signal light obtained by reflecting light emitted by the light source to the fingerprint identification unit through a touch main body; the fingerprint identification unit is fixed to the display substrate through the through hole; and the first protective layer and the second protective layer are used for diffusing a stress at the fingerprint identification unit. The mechanical strength of the display panel with a fingerprint identification function is improved, so that the service life is prolonged.
Description
technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel and a display device. Background technique [0002] Fingerprint is an innate and unique biological feature. It consists of a series of ridges and valleys on the skin surface of the fingertips to form details such as arches, left-handed, right-handed, and spirals. With the development of fingerprint recognition technology, Various display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. [0003] With people's requirements for performance and appearance of various display devices with fingerprint recognition functions, in-screen fingerprint recognition technology has become a current research hotspot. The current popular in-screen fingerprint recognition system is to install the fingerprint recognition module under the organic light-emitting diode (OLED) displa...
