Our TFT (Thin-Film Transistor) displays are active-matrix LCDs with full RGB color screens. These screens exhibit bright, vivid colors and have the ability to show fast animations, complex graphics and crisp custom fonts. Our TFTs are categorized into three classes: standard, premium and sunlight readable. In addition, a Capacitive or resistive touchscreen can be affixed to the display for a more engaging user experience.

STANDARD TFT DISPLAYS

TFTs Standard TFT Displays are TN (Twisted Nematic) displays that offer basic characteristics such as wide operating temperatures ranging from -20°C to +75°C, 12 or 6 o'clock viewing angles, and support full color motion graphics. These displays are an affordable option for various applications that require full color graphics.


Standard TFT displays

FEATURES

  • • Crisp image quality
  • • Fast response time
  • • Bright LED backlights
  • • Optional touch panels
  • • Wide viewing angles
  • • Wide operating temperature
  • • RoHS compliant

PREMIUM TFT DISPLAYS

Premium TFT Displays offer brighter backlights and wider viewing angles than our standard TFT displays. By using MVA (Multi-domain Vertical Alignment) technology, these displays offer rich blacks and have the ability to retain constant color reproduction at up to 75° angles from all sides. Premium TFT displays also have higher brightness LEDs than the standard TFT displays giving these display types a better overall picture quality for more visually demanding applications.


Premium TFT displays

FEATURES

  • • High brightness and contrast
  • • MVA viewing angles (~75° all sides)
  • • Fast response time
  • • Bright LED backlights
  • • Optional touch panels
  • • RoHS compliant

MVA TECHNOLOGY


MVA technology diagram

MVA (Multi-domain Vertical Alignment) displays can offer wide viewing angles, good black depth, fast response times and good color reproduction and depth. Each pixel within a MVA type TFT consists of three sub-pixels (Red, Green and Blue).


Each of these sub-pixels is divided further into two or more sub-pixels, where the liquid crystals are randomly lined up due to the ridged polarized glass. When a charge is applied to the transistor, the crystals twist.


With these crystals being randomly placed, it allows the backlight to shine through in all different directions keeping the intended color saturation retained while giving the display a 150° viewing angle. We offer this technology in our Premium TFT models with the option of a resistive or capacitive touch panel.

SUNLIGHT READABLE TFTS


Sunlight Readable TFT Displays are our high end TFT displays that feature the brightest backlights with the richest color reproduction out of all of our TFT options. By using a 3m enhancement film and LED backlights rated up to 1,000 cd/m2, these displays perform well in all environments including direct sunlight. Sunlight Readable TFT Displays are the perfect solution for applications looking for a full color graphic display that can perform even in the brightest conditions.

  • • 3M enhancement film
  • • Fast response time
  • • Wide viewing angles
  • • Wide operating temperature
  • • Optional touch panels
  • • RoHS compliant

HOW TFTS WORK

TFTs are Active-Matrix LCDs that have tiny switching transistors and capacitors. These tiny transistors control each pixel on the display and require very little energy to actively change the orientation of the liquid crystal in the display. This allows for faster control of each Red, Green and Blue sub-pixel cell thus producing clear, fast-moving colorful graphics. The transistors in the TFT are arranged in a matrix on the glass substrate. Each pixel on the display remains off until addressed by applying a charge to the transistor.

Unlike conventional Passive-Matrix displays, in order to activate a specific pixel, the corresponding row is turned on and a charge is sent down the proper column. This is where only the capacitor at the designated pixel receives a charge and is held until the next refresh cycle. Essentially, each transistor acts as an active switch. By incorporating an active switch, this limits the number of scan lines and eliminates cross-talk issues.

HOW COLOR IS PRODUCED

TFT color pixels

The pixels of the TFTs are divided into sub-pixels capable of producing various intensities of Red, Green or Blue. The mixture of color and levels of intensity allows for an accurate depiction of any combination of 16.7 million colors.
