Abstract
An OLED display panel and a manufacturing method of the same are provided. The OLED display panel includes a base plate, a first electrode layer and a pixel definition layer on a first side of the base plate, a plurality of electroluminescent layers on the first electrode layer, a second electrode layer covering the pixel definition layer and the plurality of electroluminescent layers, an encapsulation layer covering the second electrode layer, a black matrix and a color filter layer on the encapsulation layer and a plurality of photosensitive fingerprint sensors on a second side of the base plate; a plurality of light-transmitting holes are arranged in the black matrix, and orthographic projections of the plurality of light-transmitting holes on the second electrode layer are in hollow-out regions of the second electrode layer, respectively; and the photosensitive fingerprint sensors are in the orthographic projections of the light-transmitting holes, respectively.
