  • Patent number: 4110662
    Abstract: A thin film electronic device is detailed for processing information signals and storing line-at-a-time assembled information signals for driving an X-Y matrix coincidence addressable, display panel. The thin film device is preferably integrally formed on the periphery of the display panel and acts as a serial to parallel converter to process the information signal to present it for line-at-a-time addressing. The device is usable for alpha numeric and refresh signals as well as for TV rate video information.

  • Patent number: 4096821
    Abstract: A system is disclosed for fabricating thin-film electronic components upon a substrate. A unitary metal aperture mask is utilized which includes a plurality of linearly aligned aperture patterns formed in the unitary mask. The mask is coupled with a linear motion assembly, and an electro-optic sensor which reads position indicating alignment marks upon the mask to provide precise and accurate mask alignment during subsequent fabrication steps in the vacuum deposition process. This system avoids the use of individual deposition masks which must be successively aligned.
