  2. TFT LCD - Wikipedia

    en.wikipedia.org/wiki/TFT_LCD

    TFT dual-transistor pixel or cell technology is a reflective-display technology for use in very-low-power-consumption applications such as electronic shelf labels (ESL), digital watches, or metering. DTP involves adding a secondary transistor gate in the single TFT cell to maintain the display of a pixel during a period of 1s without loss of ...

  3. Active-matrix liquid-crystal display - Wikipedia

    en.wikipedia.org/wiki/Active-matrix_liquid...

    An active-matrix liquid-crystal display (AMLCD) is a type of flat-panel display used in high-resolution TVs, computer monitors, notebook computers, tablet computers and smartphones with an LCD screen, due to low weight, very good image quality, wide color gamut and fast response time.

  4. Liquid-crystal display - Wikipedia

    en.wikipedia.org/wiki/Liquid-crystal_display

    A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers to display information.

  5. Thin-film transistor - Wikipedia

    en.wikipedia.org/wiki/Thin-film_transistor

    In 1973, T. Peter Brody, J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories developed a CdSe (cadmium selenide) TFT, which they used to demonstrate the first CdSe thin-film-transistor liquid-crystal display (TFT LCD). [31] [36] The Westinghouse group also reported on operational TFT electroluminescence (EL) in 1973, using CdSe. [37]

  6. Indium gallium zinc oxide - Wikipedia

    en.wikipedia.org/wiki/Indium_gallium_zinc_oxide

    IGZO-TFT and its applications are patented by JST. [4] They have been licensed to Samsung Electronics [4] (in 2011) and Sharp [5] (in 2012). In 2012, Sharp was the first to start production of LCD panels incorporating IGZO-TFT. [6] Sharp uses IGZO-TFT for smartphones, tablets, and 32" LCDs. In these, the aperture ratio of the LCD is improved by ...

  7. List of flat panel display manufacturers - Wikipedia

    en.wikipedia.org/wiki/List_of_flat_panel_display...

    This list includes LCD, OLED and microLED display manufacturers. LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material.

  8. Active matrix - Wikipedia

    en.wikipedia.org/wiki/Active_matrix

    Active matrix is a type of addressing scheme used in flat panel displays.It is a method of switching individual elements of a flat panel display, known as pixels.Each pixel is attached to a transistor and capacitor that actively maintain the pixel state while other pixels are being addressed, in contrast with the older passive matrix technology in which each pixel must maintain its state ...

  9. Hitachi HD44780 LCD controller - Wikipedia

    en.wikipedia.org/wiki/Hitachi_HD44780_LCD_controller

    The data sheet indicates that for a resistor of 91 kΩ at V CC =5 V the oscillator can vary between 190 kHz and 350 kHz resulting in wait times of 52.6 μs and 28.6 μs instead of 37 μs. If a display with the recommended 91 kΩ resistor is powered from 3.3 volts the oscillator will run much slower.
