Abstract: A Photoelectric sensing array system with daughter boards daisy chained together so that varying size touch systems can be modularly constructed using the same electronics. The system also provides for increased touch resolution.

Abstract: A process for the manufacture of a hollow gas-filled Plasma-shells for a gas discharge device. The Plasma-shell is located in or on a substrate within the device with a dome side or flat side facing the viewing direction.

Abstract: There is disclosed and claimed new and improved photoelectric sensing array system, method, and apparatus for large area IR touch screens to increase the resolution of the array, and to provide ease of manufacture and testing.

Abstract: The priming or conditioning of an AC gas discharge plasma display panel for improved selective write and selective erase which comprises addressing n number of rows in an order or sequence that is changed from frame to frame such that later rows to be addressed are advanced in the sequence with each subsequent frame. Each frame consists of the addressing of all n rows. Specific embodiments include the use of plasma-shells, plasma-tubes, and/or combinations thereof.

Abstract: Visual artifact reduction method for a display comprising the use of gamma correction. Other artifact reduction methods can be used with gamma corrections including error diffusion, dithering, and center of light.

Abstract: There is disclosed the simultaneous addressing and sustaining of a gas discharge AC plasma display comprised of a multiplicity of Plasma-shells wherein the Plasma-shells in at least one section of the display are addressed while the Plasma-shells in at least one other section of the display are being simultaneously sustained. Plasma-shell includes Plasma-sphere, Plasma-disc, and Plasma-dome.

Abstract: There is disclosed the simultaneous addressing and sustaining of a surface discharge AC plasma display panel wherein at least one section of the panel is addressed while at least one other section of the panel is being simultaneously sustained. In one embodiment a reset voltage is applied to at least one section while at least one other section is being simultaneously addressed. In another embodiment, the reset voltage period in the one section is long enough to allow addressing in the other section followed by sustaining in the other said section.

Abstract: There is disclosed visual artifact reduction methods for a display comprising the use of gamma corrections, error diffusion, dithering, and/or center of light. The invention is described with reference to an AC gas discharge display (PDP), but may be practiced with other display technologies. The methods of this invention are disclosed for use with a number of PDP structures and PDP electronic addressing architectures including ADS, SAS, and ALIS. In one preferred embodiment, a center of light timing method is used to reduce artifacts between different sections of a PDP being addressed with SAS architecture.
