The present invention provides an organic light emitting diode (OLED) display panel and an intelligent terminal, including: an electronic element region in which sensor elements are disposed; and a pixel region provided with at least one light transmissive region. The electronic element region is arranged corresponding to the at least one light transmissive region, multiple sub-pixels are arranged in the pixel region. Pixel density of the sub-pixels is gradually decreased along a direction toward a center of the pixel region.
