Latest Patents

Voisin's latest patents showcase his innovative thinking and technical expertise. One of his notable inventions is a display device that includes a liquid crystal screen with a secured display. This invention primarily focuses on creating a liquid-crystal matrix screen composed of elementary pixels. The screen features a first electrode, referred to as the 'backplane,' which serves as a voltage reference, and a second electrode in the form of a matrix electronic network that delivers drive voltages for controlling the pixels. This invention operates in 'normally black' mode, ensuring that optical transmission of the pixels is minimal when no voltages are applied. Notably, the drive voltage for the backplane is a variable periodic voltage, enabling sufficient optical transmission for detection by an observer.

Another crucial patent by Voisin is a shift register designed for an active-matrix flat screen. This shift register is driven by two complementary clock signals and is integrated onto an active-matrix substrate to control the selection of rows of image points on the flat screen. The design includes a control transistor driven by one of the clock signals, facilitating enhanced operation and efficiency.
