In a fingerprint recognizable organic light-emitting diode (OLED) display panel and display device provided by the present disclosure, optical fingerprint recognition is implemented by a fingerprint recognizing sensor formed by poly-Si in a thin film transistor array of the OLED display panel. Space for disposing the fingerprint recognizing sensor is enlarged because the space occupied by the poly-Si in the thin film transistors array is narrowed by reducing the number of thin film transistors. In addition, the optical fingerprint recognizing sensors are disposed within the display panel, therefore, the display panel can implement image display and fingerprint recognition sensing at the same time. As a result, the usage experience is improved because fingerprint recognition sensing can be implemented in display area. The OLED display panel of the present disclosure can be applied in a liquid crystal display panel.
