Display panel and display device

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a substrate base plate; an array layer positioned on one side of the substrate base plate; adisplay layer positioned on one side, deviating from the substrate base plate, of the array layer; a color filter layer located on the side, deviating from the array layer, of the display layer, wherein the color filter layer comprises a first shading layer and a color resistor, and the first shading layer comprises a plurality of first imaging small holes; a touch layer positioned between the color filter layer and the display layer; a second shading layer which is located on the side, deviating from the color filter layer, of the display layer and comprises a plurality of second imaging small holes corresponding to the first imaging small holes; and a light sensation sensor layer used for detecting an image formed by the second imaging small holes; part of light emitted by the light-emitting element serving as the small hole imaging light source is reflected by the touch layer adjacent to the first imaging small holes and then enters the area outside the second imaging small hole ofthe second shading layer. According to the technical scheme of the embodiment of the invention, the fingerprint recognition precision based on the small hole imaging principle can be improved.

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] Fingerprints are inherent to everyone. With the development of technology, a variety of display devices with fingerprint recognition functions have appeared on the market, such as mobile phones, tablet computers and smart wearable devices. Users can use Fingerprint recognition realizes functions such as unlocking and payment of the display device, simplifies the authority verification process, and improves user experience. [0003] Currently, the fingerprint recognition sensor of an organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device is usually disposed on a side away from the display surface of the OLED display device. The basic principle of fingerprint identification of OLED display device is: the external fingerprint identification light source or the organic ligh...

[0004] In addition, the touch function is also an indispensable function of the current display device. With the development of integration and thinning of the display device, the touch structure is integrated inside the display device (for example, the touch layer is arranged on the thin film encapsulation layer of the OLED. , forming a TP on TFE structure) can improve the integration of the display device, but since the touch structure includes a metal layer or a metal oxide layer, part of the imaging light will be directly reflected to the fingerprint recognition element, and this part of the light does not contain fingerprint information. Affects the imaging effect and the fingerprint recognition accuracy of the OLED display device
