Abstract

An organic light-emitting diode (OLED) display device and a manufacturing method thereof are provided. The OLED display device includes a flexible substrate, a fingerprint recognition sensor, a thin film transistor (TFT) array layer, an OLED light-emitting functional layer, a color filter layer, and a thin-film encapsulation layer. An outermost layer of the thin-film encapsulation layer is provided with a first via-hole. A collimator lens structure is embedded in the first via-hole, the collimator lens structure is configured to allow reflected light reflected by a fingerprint converged on different directions and allow the reflected light reflected in a vertical direction converged on the on the fingerprint recognition sensor.
