The present disclosure provides an OLED display apparatus and a method for producing the same, and a color filter substrate and a method for producing the same. The OLED display apparatus comprises: a TFT array substrate; a luminescent structure layer provided on the TFT array substrate, wherein light emitted from the luminescent structure layer is infrared light; and a light conversion layer located on the luminescent structure layer. The light conversion layer comprises a plurality of pixel areas, each of which is at least provided with three light conversion units, which are a red light conversion unit formed of an upconversion luminescent material emitting red light after stimulation by infrared light, a green light conversion unit formed of an upconversion luminescent material emitting green light after stimulation by infrared light, and a blue light conversion unit formed of an upconversion luminescent material emitting blue light after stimulation by infrared light.
