Patent ID: 11271189

Abstract:
An organic light emitting diode (OLED) display panel with a light field camera includes a glass covering plate, an OLED pixel layer, and image sensor. A gradient refractive index lens is formed on the glass covering plate. A refractive index of the gradient refractive index lens gradually varies from a center of the gradient refractive index lens to an outer periphery. The OLED pixel layer is disposed on a bottom surface of the glass covering plate and includes OLED pixel units. A micro lens array is embedded on the OLED pixel layer and includes gradient refractive index micro lenses. A refractive index of each gradient refractive index micro lens gradually varies from a center of the gradient refractive index micro lens to an outer periphery. The image sensor is disposed on a bottom surface of the OLED pixel layer. The light field camera can acquire clear images without focusing.
