Claim:
1. A pixel element structure, comprising: first, second, and third sub-pixel elements, each comprising a light-emitting region, wherein at least one of the first, second, and third sub-pixel elements comprises a light-transmitting region different from the light-emitting region and arranged as a transparent film layer structure comprising a transparent insulation layer and a transparent organic film layer, wherein the light-emitting region comprises an organic light-emitting diode light-emitting structure, and wherein the organic light-emitting diode light-emitting structure comprises: a first substrate, and a nontransparent anode, a pixel defining layer, an organic layer and a cathode, sequentially arranged above the first substrate, wherein when the pixel element structure is turned off, a scene on an opposite side of the pixel element structure is observed by an observer on either side of the pixel element structure, and when the pixel element structure is turned on, a scene on the opposite side of the pixel element structure is observed by the observer on a side where no light is emitted, and a scene on the opposite side of the pixel element structure is not observed by the observer on a side where the light is emitted.
