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 embodiment of the invention provides an organic light emitting display panel and a display device. By means of distributed arrangement of supporting units in the display panel and the position adjustment of an opening area of a light emitting unit, on one hand, in the embodiment of the invention, an edge corner area of the supporting unit is close to the opening area of the light emitting unitas much as possible by reducing a relative side length of the supporting unit and the opening area of the light emitting unit, so that the distance between the supporting unit and the opening area ofthe light emitting unit is increased, as a result, the projection area of the supporting unit in the opening area of the light emitting unit is decreased, in this way, when the supporting unit generates deformation and even collapse due to an external pressure, the damage to the opening area of the light emitting unit is reduced. On the other hand, in the embodiment of the invention, by means ofthe distributed arrangement of the supporting units and the position adjustment, the supporting units are arranged in a non-transparent area as much as possible, thus increasing an effective light transmission area on the display panel, and in this way, the overall light transmittance is greatly improved, and the sensitivity of light sensing fingerprint recognition is improved.

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] 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, the display area can be reused as the fingerprint recognition area by using the under-screen fingerprint technology. When the display area is multiplexed as a fingerprint identification area, multiple fingerprint identification units are also arranged in the position corresponding to the fingerprint identification area in the display panel. When fingerprint identification is performed, 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 identifies valleys and ridges of the fi...
