Display panel and display device

Abstract

The invention discloses a display panel and a display device. The display panel comprises a first display area, a second display area and a third display area, wherein the first display area comprisesan underlayer substrate, a first thin film transistor layer, a first organic light-emitting display layer, a packaging layer, a touch layer and a first functional layer; the first thin film transistor layer is arranged on the underlayer substrate, and photodiodes are arranged in the first thin film transistor layer; the first organic light-emitting display layer is arranged on the first thin filmtransistor layer, the first organic light-emitting display layer comprises a first pixel defining layer, the first pixel defining layer comprises a plurality of first openings and a plurality of second openings, the first openings are used for accommodating sub-pixels, and the photodiodes are arranged corresponding to the second openings; the packaging layer and the touch layer are arranged on the first organic light-emitting display layer; the first functional layer is arranged on the touch layer and comprises a first shading layer and a first color filter layer, and the first shading layeris provided with openings in the positions corresponding to the second openings. By optimizing the internal structure of the display panel, the integration level of the screen body is improved, so that the comprehensive performance of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the continuous development of display technology, users have higher and higher requirements on display devices. Terminal display devices (especially smart phones) are developing in the direction of flexibility, full screen, and high integration. [0003] At present, although functional products such as under-display camera (Under Display Camera, UDC), under-display fingerprint recognition (Fingerprint on Display, FOD), embedded touch TP in the screen, and flexible folding have appeared in terminal display devices, the integration level is still high. Insufficient; especially in the current structure of flexible folding products, there are many external bonding components (such as TP, polarizer POL, optical glue OCA, etc.), which lead to problems such as excessive hardness, thick ...

Problems solved by technology

[0003] At present, although functional products such as under-display camera (Under Display Camera, UDC), under-display fingerprint recognition (Fingerprint on Display, FOD), embedded touch TP in the screen, and flexible folding have appeared in terminal display devices, the integration level is still high. Insufficient; especially in the current structure of flexible folding products, there are many external bonding components (such as TP, polarizer POL, optical glue OCA, etc.), which lead to problems such as excessive hardness, thick thickness, and low transmittance in the internal structure. Ultimately affect the phone's screen-to-body ratio, flexible bending, screen body power consumption and other performance
