2. Liquid-crystal display - Wikipedia

   en.wikipedia.org/wiki/Liquid-crystal_display

   The crystals may exist in one of two stable orientations ("black" and "white") and power is only required to change the image. ZBD Displays is a spin-off company from QinetiQ who manufactured both grayscale and color ZBD devices. Kent Displays has also developed a "no-power" display that uses polymer stabilized cholesteric liquid crystal (ChLCD ...

3. Polarizer - Wikipedia

   en.wikipedia.org/wiki/Polarizer

   In addition, the width of each wire should be small compared to the spacing between wires. Therefore, it is relatively easy to construct wire-grid polarizers for microwaves, far-infrared, and mid-infrared radiation. For far-infrared optics, the polarizer can be even made as free standing mesh, entirely without transmissive optics.

4. Surface-conduction electron-emitter display - Wikipedia

   Canon began SED research in 1986. [5] Their early research used PdO electrodes without the carbon films on top, but controlling the slit width proved difficult. At the time there were a number of flat-screen technologies in early development, and the only one close to commercialization was the plasma display panel (PDP), which had numerous disadvantages – manufacturing cost and energy use ...

5. Liquid crystal on silicon - Wikipedia

   en.wikipedia.org/wiki/Liquid_crystal_on_silicon

   LCos display systems typically consist of three main components: the LCos panel, the light source, and the optical system. The LCos panel is the heart of the display system. It consists of an array of pixels that are arranged in a grid pattern. Each pixel is made up of a liquid crystal layer, a reflective layer, and a silicon substrate.

6. Field-emission display - Wikipedia

   en.wikipedia.org/wiki/Field-emission_display

   A field-emission display (FED) is a flat panel display technology that uses large-area field electron emission sources to provide electrons that strike colored phosphor to produce a color image. In a general sense, an FED consists of a matrix of cathode-ray tubes , each tube producing a single sub-pixel, grouped in threes to form red-green-blue ...

7. Twisted nematic field effect - Wikipedia

   en.wikipedia.org/wiki/Twisted_nematic_field_effect

   The twisted nematic effect (TN-effect) was a major technological breakthrough that made the manufacture of large, thin liquid crystal displays practical and cost competitive. Unlike earlier flat-panel displays, TN-cells did not require a current to flow for operation and used low operating voltages suitable for use with batteries.
