The invention relates to a chip card comprising, a molded card body made by means of injection molding and, an integrated circuit chip, as well as to a method for manufacturing such a card. Annealing after impurities have been doped is carried out through light irradiation. The photorefraction ocular screening device is comprised of an LED arrangement configured with a plurality of irradiation sources serving as visual stimuli, wherein the visual stimuli may be presented in varying illumination patterns to the pupils of an examinee for expanding the range of ocular responses that can be used to determine refractive error. Moreover, the apparatus and method enable the same information to be provided to a plurality of cells and enable a streaming-type service to be processed in a common MBMC layer commonly used in the cells. The method maintains the charging potential by compensating for a residual potential of the OPC, thus improving a performance of a printer.
