Problems solved by technology

[0003] However, in the prior art, due to the relatively compact arrangement of various film layers and other components in the drive unit of the display panel, the proportion of the light-transmitting area on the display panel is not high, which affects the exit and entry of light and thus affects Light-sensitive fingerprint recognition sensitivity

Abstract

The embodiments of the present invention provide an organic light-emitting display panel and a display device, which are adjusted by the dispersed arrangement of the support units in the display panel and the position adjustment with the opening area of ​​the light-emitting unit. On the one hand, in the embodiment of the present invention, by reducing the relative length of the opening area of ​​the support unit and the light-emitting unit, the edge corner area of ​​the support unit is as close to the opening area of ​​the light-emitting unit as possible, and the gap between the support unit and the opening area of ​​the light-emitting unit is enlarged. The distance between them reduces the projected area of ​​the support unit on the opening area of ​​the light-emitting unit. Therefore, when the supporting unit receives external pressure and deforms or even collapses, damage to the opening area of ​​the light-emitting unit is reduced. On the other hand, in the embodiment of the present invention, by dispersing the arrangement and position adjustment of the supporting units, the supporting units are arranged in the non-transmissive area as much as possible, thereby increasing the effective translucent area on the display panel, thereby greatly improving the overall The light transmittance improves the sensitivity of light-sensitive fingerprint recognition.

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 the display panel with fingerprint recognition function, in order to better realize the full-screen design and avoid the fingerprint recognition area occupying the space of the non-display area, at present, the display area can be reused as the fingerprint recognition area by using the fingerprint recognition technology under the screen. When the display area is multiplexed into a fingerprint identification area, a plurality of fingerprint identification units are also arranged at the positions corresponding to the fingerprint identification area in the display panel. During fingerprint identification, the light emitted by the light source is reflected by the finger and enters the fingerprint in a specific area. In the identification unit, the fingerprint identification unit further identifi...
