Abstract

An organic light-emitting diode display panel includes a lower substrate; an upper substrate; and an organic light-emitting diode structure formed between the lower substrate and the upper substrate. A side of the organic light-emitting diode structure facing towards the upper substrate is a light output side, and the upper substrate is a strengthened glass plate, subjected to a strengthening processing, which serves as a protective glass plate as an outermost layer of the organic light-emitting diode display panel.
