1968: RCA's Bernard Lechner demonstrated a dynamic scattering LCD. While not commercially viable, this marked an important step in showing the potential of liquid crystals for display applications.
1969: James Fergason, while working at Westinghouse, invented the twisted nematic (TN) LCD. This invention was a major breakthrough as it offered improved contrast and lower voltage requirements compared to previous LCD designs. Fergason later formed his own company, ILIXCO, and patented his invention, which became the basis for most LCDs used in watches and calculators.
1972: Peter J. Wild and Martin J. Green at Brown Boveri Research Center in Switzerland developed the active matrix addressing scheme for LCDs. This technology used thin-film transistors (TFTs) to control individual pixels, resulting in significantly improved image quality and response times.
Late 1980s - Early 1990s: Japanese companies such as Sharp, Toshiba, and Hitachi invested heavily in the development and commercialization of TFT-LCD technology. They overcame numerous manufacturing challenges and gradually improved the size, resolution, and image quality of LCD panels.

Plasma Displays

Plasma display technology relies on small cells containing noble gases. When voltage is applied, the gas ionizes, forming a plasma that emits ultraviolet (UV) light. This UV light then excites phosphors, which emit visible light in red, green, and blue colors to create an image. Key developments in plasma display technology include:

1964: Donald Bitzer, Gene Slottow, and Robert Willson at the University of Illinois created the first plasma display panel, known as the PLATO display. This display was a monochrome (orange) display used for educational computer terminals.
1992: Larry Weber, while working at the University of Illinois, developed key innovations in plasma display technology, including the "sustaining voltage" technique, which reduced power consumption and improved the lifespan of plasma displays.
Mid-1990s: Companies like Fujitsu, Pioneer, and Panasonic invested heavily in the development and commercialization of color plasma display panels. They faced challenges in improving brightness, contrast, and energy efficiency, but eventually succeeded in producing large, high-quality plasma televisions.

Organic Light-Emitting Diode (OLED) Displays

OLED technology is based on organic compounds that emit light when an electric current is applied. OLED displays offer several advantages over LCD and plasma displays, including higher contrast ratios, wider viewing angles, faster response times, and lower power consumption. Key milestones in OLED technology include:

1950s: André Bernanose and his team at the Nancy University in France were the first to observe electroluminescence in organic materials.
1987: Ching W. Tang and Steven Van Slyke at Eastman Kodak created the first practical OLED device. Their device used a multi-layer structure to improve efficiency and stability, paving the way for commercial OLED displays.
Early 2000s: Companies like Sony, Samsung, and LG began investing in the development and commercialization of OLED displays. They faced challenges in improving the lifespan and color purity of OLED materials, but eventually succeeded in producing small OLED displays for mobile phones and other portable devices.
2010s: LG Display became the leading manufacturer of large-sized OLED panels for televisions. They developed innovative manufacturing techniques, such as white OLED (WOLED) with color filters, to improve the performance and reduce the cost of OLED TVs.

Trends and Latest Developments

The flat screen television market is constantly evolving, with new technologies and trends emerging regularly. Here are some of the latest developments:
