NDIS Corporation

 NDIS corporation is a technologically innovative company that develops crucial technologies for the latest display and optical devices.

  The company name, NDIS is short for next-generation display, considered likely to highly develop existing LCD technology such as Flexible Display, Smart Window, LC Lens and etc.  For instance, we develop flexible displays, see-through displays, autostereoscopic 3D displays, LC-based smart window film, LC lens with tunable focal length, etc.   We have our own technologies to design and manufacture such high-tech core devices.

  • Established  July 23, 2004.
  • Business Area  :  Smart Window, Flexible Display, 3D Display

NDIS Vision

 NDIS is a display company made up of top LCD experts which are specialized in next generation displays.

  An object of NDIS is to provide a clear, brighter, transmissive and reflective full-color displays which are highly flexible, can be manufactured easily, consume little power, and can, therefore, be incorporated into a variety of applications.

  Parallax and Lenticular 3D display modules and flexible display modules have been developed by NDIS while LC-based Smart Window Film, LC Lens with Tunable Focal Length and See-Through displays are among developing items that can attract great interest from the market.

  With its unique Flexible LCD and ChLC technologies, embodiment of the display media can be printed or R2R processed, therefore the displays themselves can be made inexpensively in large quantities.

  As you can imagine, prospects of LC Lens technology is very bright.
  So, utilizing LC Lens and optical technologies of NDIS, we've started advancing into the AR market using Smart glasses with tunable focal length technology.

LCDs in general

  • LCDs
     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. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome.
     LCDs are used in a wide range of traditional applications including LCD televisions, computer monitors, instrument panels, aircraft cockpit displays, and indoor and outdoor signage and expended to non-traditional applications such as see-through displays, autostereoscopic 3D displays, LC-based smart window film, LC lens with tunable focal length.
     LCD has many advantages such as compact, thin and light, Low power consumption causing little heat emitted during operation, no geometric distortion. sharp image with no bleeding or smearing and so on. 
     Since LCD panels produce no light of their own, they require external light to produce a visible image. In a transmissive type of LCD, this light is provided at the back of the glass stack, backlight. While passive-matrix displays are usually not backlit (e.g. calculators, wristwatches), active-matrix displays almost always are.

  • Two addressing schemes, Passive-matrix and Active matrix
     Passive matrix LCDs are still used for applications, such as inexpensive calculators, watches, digital cameras and instrument panels. In particular, these are used on portable devices where less information content needs to be displayed, lowest power consumption (no backlight) and low cost are desired or readability in direct sunlight is needed.
      Active matrix is a type of addressing scheme used in flat panel displays using a matrix of thin-film transistors. In this method of switching individual elements (pixels), each pixel is attached to a transistor and capacitor actively maintaining 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 passively.  Active-matrix addressed displays look brighter and sharper than passive-matrix addressed displays of the same size, and generally have quicker response times, producing much better images.

  • Transmissive, Reflective and Transreflective Displays
     The LCDs are largely classified into transmission LCDs based on a transmission method and reflective LCDs based on a reflection method.
     Besides these two displays, there is another type of LCDs, transflective liquid-crystal display, which is a liquid-crystal display (LCD) that reflects and transmits light.  Under bright illumination (e.g. when exposed to daylight) the display acts mainly as a reflective display with the contrast being constant with illuminance. Only in dim and dark ambient situations is an auxiliary transmissive backlight needed.
     An early application were digital LCD wristwatches. In dim ambient light or at night a pushbutton-activated backlight allowed reading of the display in its transmissive mode. Digital time displays in alarm clocks for bedrooms still work this way. The backlighting is dim, so that the display is comfortably readable at night. Some 21st century smart watches such as the Pebble Smart watch also use transflective LCDs.

  • Ch-LCD
     There are many LCD modes, like TN, STN, VN in general and also a special one, Cholsteric.
     A cholesteric liquid crystal display (ChLCD) is a display containing a liquid crystal with a helical structure and which is therefore chiral. Cholesteric liquid crystals are also known as chiral nematic liquid crystals. 
     The technology is characterized by stable states i.e. focal conic state (dark state) and planar state (bright state). Displays based on this technology are called “bistable” and don’t need any power to maintain the information. In other words once the addressing voltage is removed, any optical state remains fixed. Power is only required for information changes.
     Because of its very low power consumption, this technology is highly preferred to be used in self-sustaining applications.
     Using the reflective nature of the ChLCD, the display can be perfectly read under sunlight conditions.    → See more in Flexible Displays

NDIS handles many kind of LCD mode such as TN, VA and ECB including Cholesteric LC,  and also Transmissive and Reflective LCDs.

Since its inception, NDIS has been providing with customers customized samples relating to new LCD technologies, 

such as Holographic AR Device, 3D Lens, Transparent display, etc.


  NDIS holds more than 30 domestic and overseas patents related to smart windows, flexible display and autostereoscopic display technologies.
