ABSTRACT:
Image source, for converting image data in the form of serial charges into a high-resolution imagewise light pattern, includes a CCD emitter having a semiconductor charge-coupled device (CCD) structure for receiving and transferring the charges, a charge amplification means including a charge-modulated control field effect transistor structure (C-FET), and plural small-scale field emission cells (FEC). The CCD emitter is operable to convert the charges to an imagewise pattern of electron emissions that are directed to a luminescent phosphor layer susceptible to light output according to the impact of the incident electrons. The light output may be directed onto a photosensitive image recording medium to provide means for image recording, or in alternative embodiments, the light output may be viewed directly.

W. S. Boyle and G. E. Smith disclose in "Charge Coupled Semiconductor Devices", Bell System Technical Journal, v. 49, Apr. 1970, pp. 587-593, that the basic shift register concept may be used to construct a recirculating memory or used as a delay line. A display device is said to be constructed by the process of reading in the information (minority carriers) via shift register action and then forward biasing the MIS structure to force the minority carriers into the bulk where radiation recombination takes place.
