Chester F Bassetti Jr: System and method for blinking digitally-commanded pixels of a display screen to produce a palette of many colors. Cirrus Logic, Limbach & Limbach, June 16, 1992: US05122783 (73 worldwide citation)

A frame rate duty cycle technique and dithering technique is applied to the output of a color look-up RAM in order to drive various flat panel displays. An integrated circuit chip in accordance with the invention includes a modulo-N gray scaling unit, where the value N is variable as well as a pixel ...

Chester F Bassetti Jr, Dayakar C Reddy, Ekaputra Laiman, Bryan M Richter: Method and apparatus for producing perception of high quality grayscale shading on digitally commanded displays. Cirrus Logic, Limbach Limbach & Sutton, February 9, 1993: US05185602 (50 worldwide citation)

The perception of grayscale shading on a digitally commanded display is produced by commanding pixels of the display with brightness-setting signals of differing average duty cycles. Brightness-setting signals having one brightness level associated with them are phase shifted in relation to time and ...

A graphics controller uses spread-spectrum techniques to modulate the pixel clock over a range of frequencies, reducing the maximum intensity of EMI emissions. When the clock input to the graphics controller is replaced with a modulated clock, the image on a CRT is distorted. Distortion is avoided b ...

Chester F Bassetti: Programmable burst of line-clock pulses during vertical retrace to reduce flicker and charge build-up on passive LCD display panels during simultaneous LCD and CRT display. NeoMagic, Stuart T Auvinen, August 4, 1998: US05790083 (25 worldwide citation)

A graphics controller drives a flat-panel display and simultaneously drives an external cathode-ray-tube (CRT) display. Horizontal clock pulses continue to be applied to the flat panel during the CRT's vertical blanking or re-trace period so that the flat panel is not left in a constant state during ...

Chester F Bassetti: Micro-electro-mechanical switch (MEMS) display panel with on-glass column multiplexers using MEMS as mux elements. Nuelight, Stuart T Auvinen, December 6, 2005: US06972881 (14 worldwide citation)

A display has an array of Micro-Electro-Mechanical Switches (MEMS) display elements on a substrate such as glass. Rather than directly drive all columns of the MEMS display elements from off-substrate column drivers, column mux logic is placed on the substrate. The column mux logic uses MEMS contact ...

Chester F Bassetti: Display system with highly linear, flicker-free gray scales using high framecounts. NeoMagic Corporation, Henry K Woodward, Townsend and Townsend and Crew, September 8, 1998: US05805126 (14 worldwide citation)

A circuit system for generating phase values and frame counts, particularly adapted for liquid crystal displays is described. The phase values are generated by 8.times.8 matrices, which are formed, in turn, from smaller matrices. The circuit system handles a large number of gray scale levels, 64, wh ...
