Abstract

The invention discloses an electroluminescent display panel and a display device. According to the electroluminescent display panel and the display device, a light-sensing fingerprint identification area is arranged, so that a second light-emitting unit in a light-sensing identification pixel unit is enabled to be a transparent light emitting unit. Furthermore, during the optical fingerprint identification process, the fingerprint identification area can be used for effectively detecting fingerprints. Moreover, the light-sensing fingerprint identification area comprises a display sub-pixel unit and a light-sensing identification pixel unit. Therefore, the display function of the light-sensing fingerprint identification area can also be achieved. As a result, the occupied area of the non-display area is effectively reduced. The design of a narrow frame is facilitated.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an electroluminescent display panel and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display is a self-luminous display, and has the characteristics of thinness, high chromaticity, wide viewing angle and fast response speed, and has great development prospects in the field of display technology. In order to make the display have fingerprint recognition function, such as figure 1 As shown, generally, a fingerprint identification area is provided in the non-display area 2 of the display panel 1, and a fingerprint identification structure 3 is usually provided in the fingerprint identification area; however, in figure 1 In the shown structure, since the fingerprint identification structure 3 is arranged on the non-facing side of the display panel 1, the thickness of the display panel 1 is significantly increased, which is not conducive to the...
