The abbreviation TFT LCD display actually stands for a thin film transistor liquid crystal display.

The internal construction of a TFT display consists of glass that has a semiconducting material along the top for functionality. Every pixel inside the TFT display utilizes an individual transistor on top of the liquid crystal material.

Liquid crystal gets its name because it is similar to liquid since it can change quickly to display different images and the crystal comes from its ability to stay in the newly arranged position. The transistor then applies a low amount of voltage to the pixel to determine each pixel's intensity and color. These pixels all blend together to create the images for pictures and video.

The TFT display may also be known as an active-matrix LCD in some settings. While TFT isn't the only active-matrix LCD technology, it is very popular and why you may notice that people use the term TFT instead of active-matrix when describing a display. The TFT is not the only component that creates the active-matrix LCD. The term active-matrix actually stems from the ability of the display to control each pixel individually and switch them over quickly as needed.

Passive-matrix LCDs vary from active-matrix LCDs. The TFT display is defined by a high contrast, fast response time and a high refresh rate. On the other hand, a passive-matrix LCD is found in much smaller displays such as a digital wristwatch or calculator screen. These do not require the full colours that active-matrix LCDs provide in computer screens, televisions and mobile phones.  

Two types of thin film transistor technologies are commonly found and used with TFT displays. The first and most common is the twisted nematic, which is also known as a TN display. Its primary selling point is a very fast response time. They may appear low quality at awkward angles or when reproducing certain colours. The other type is IPS or in-plane switching. It has better colours and viewing angles, but has slower refresh rates as a tradeoff.

  • Sunlight Readable...

    Ultra-Bright TFT-LCD series.

    In situations of high ambient brightness outdoors or in direct sunlight, the content on TFT displays with normal brightness is often difficult to read.

    The sunlight readable product range utilizes super bright LED backlights, providing a luminance up 4000cd/m2. This enables the displays to be readable under direct sunlight, and gives you the intensity and brilliance your Avionics, Automotive Car Charging, Industrial, Marine, Medical and Scientific applications require.

  • Capacitive Touch Displays

    Projected Capacitive Touch provides an unsurpassed experience in forceless touch, precision touch and gesture recognition. Projected Capacitive Touch keeps up tracking with fast finger movement. The touch surface is durable and drift-free in long term use as Projected Capacitive Touch touch sensors are overlaid with a surface glass. Hence they are highly impact resistant on public access systems while they can also be made light-weight for personal hand-held devices.

    Due to its highly durable and smooth surface, Projected Capacitive Touch is suitable for medical and industrial touch display applications, and an ideal touch solution for the embedded applications such as industrial data loggers, car GPS or Personal Navigation Devices, Game Consoles and personal entertainment devices.

    Supported by Projected Capacitive Touch controller firmware and drivers, Projected Capacitive Touch  sensors are provided with a turn-key solution. To help customers expedite their system development to meet market demands, a variety of touch controllers have been developed for Projected Capacitive Touch sensors of different sizes.

  • Letterbox Style Displays

    The Benefits of Bar Style or Letterbox Displays

    There are two types of ultra wide form factor displays, the first is manufactured as a Bar Style or Letterbox Display as an original unit, and the second is where a standard panel is cut horizontally to give the bar style effect.

    Bar Style or Letterbox Displays are effective at displaying informative and promotional content as they allow for high-definition images and messages across a large surface area.

    Bar Style or Letterbox Displays are especially suitable for audio systems, advertising displays, automotive applications, drone controls, industrial/scientific equipment, marine dashboards, medical equipment, server systems and security systems where height is the issue, but a lot of information is required to be displayed..

    Bar Style or Letterbox Displays can be optimised for a wide range of indoor and outdoor environments and can resist certain elements such as vibrations from vehicles and different weather conditions if they are to be installed outdoors.

    LCDTek supply Bar Style or Letterbox displays in sizes from 2.9 inch up to 27.6 inch. Most are available with sunlight readable options and CTP (capacitive touch panel).

  • High Performance Displays
  • Resistive Touch Displays
  • Extended Temperature...
  • Super Wide View Displays
  • Unified Interface...
  • Standard Displays
  • Character/Graphic...

    Character display modules range from 8x1 to 40x4 lines. These high reliability displays are ideal for industrial and consumer products – they benefit from low power consumption and a wide operating temperature range. A comprehensive range of alphanumeric LCD and character LCD products are available.

    Graphic LCD displays (liquid crystal display) are available in dot matrix format of graphic resolution including 122x32, 128x64, 128x128, 144x32, 160x128, 160x160, 160x32, 160x80, 192x64, 192x128, 240x64, 320x240. Graphic LCD modules include different options of polarizer in reflective, transmissive or transflective types. LED backlights are available in various colours including yellow/green, white, blue, red, amber and RGB.

  • OLED Displays

    OLED panels are made from organic (carbon based) materials that emit light when electricity is applied through them. Since OLEDs do not require a backlight and filters (unlike LCD displays), they are more efficient, simpler to make, and much thinner. OLEDs have a great picture quality - brilliant colors, fast response rate and a wide viewing angle. OLEDs can also be used to make OLED lighting - thin, efficient and without any harmful materials.

    The basic structure of an OLED is a cathode (which injects electrons), an emissive layer and an anode (which removes electrons). Modern OLED devices use many more layers in order to make them more efficient, but the basic functionality remains the same.

    Making an OLED involves several steps: taking a substrate, cleaning it, making the backplane (the switching and driving circuitry), depositing and patterning the organic layers and finally encapsulation the whole thing to prevent dust, oxygen and moisture damage.

  • E-Paper Displays

    Electronic paper goes by many names: e-paper, sometimes spelled as ePaper, electronic ink and (generically, after the company that manufactures it) also e ink. All of these names describe the exact same thing: a technology that mimics the appearance of ordinary ink on paper.

    What is at the very core of e paper technology: small capsules filled with a clear fluid containing tiny particles, each about as wide as a human hair.
     
    Each electronic paper display is made up of millions of such capsules in a thin film, with the particles inside the capsules of different colours and different electric charges. Electrodes are placed above and below the capsule film. When a positive or negative electric field is applied to an individual electrode, the colour particles with the corresponding charge will move either to the top or bottom of a capsule, making the surface of the e-paper display appear a certain colour.

    Since its inception, electronic paper has undergone quite a renaissance.
     
    Starting in e-readers and slowly expanding its influence, e ink has taken on new possibilities of use. One of the sectors ideally suited to the user of electronic paper is digital signage, in other words electronic signs in every shape and form.
     
    Perfect for all kinds of indoor or outdoor displays, from traffic signs to passenger information, shelf labels in stores, interactive museum signs and all types of notice boards, EPDs are being driven as the displays of traffic operators, schools, office administrators and many more.
