Enhanced Black TN (EBTN)

This display mode offers exceptional dark background because of its very low light leakage. The contrast ratio is up to 1000:1, exceeds that of conventional TN, STN and FSTN. Besides, it offers 3 best viewing directions in one display, in contrast of one direction for conventional display. Furthermore, its wide operating temperature capability extends the range of applications, including automotives.


  • Very dark background
  • Super high contrast (> 1000:1)
  • Wide viewing angle (3-side optimized)
  • Up/down: -60° / 85°
  • Left/right: -85° / 85°
  • Wide operating temperture (-30°C to 80°C)
  • available in icon, 7-segment & graphic type up to 1/64 duty


  • Automotives, Audio & Video Equipments, Watches, Remote Control, Multimeters, Water Heater, Home Appliance and etc.

Field Sequential Color (FSC) LCD

The backlight produces the fundamental colors R-G-B sequentially, the sequence is looped. A fast response LCD which is placed in front of the backlight is switched and acts as a light shutter that is controlling the brightness of each fundamental color.

The above process is run fast enough so that the R, G, B colors are "mixed" to give multi colors.

Color TN LCD

  • Color segments in positive mode display
  • White backlighting is required

Color TN LCD is different from conventional color printed TN negative display. It can show colored segments in white background with backlighting as a positive mode display. The LCD is transflective and the user can put color printing behind the LCD to give desired color performance. The additional feature is that its readability can be maintained when the backlight is off, but in grey or black patterns.

Color Printing LCD

  • External color printing technique
  • Black mask can be coated to enhance contrast

High contrast negative LCD

  • Advance technique to enhance the contrast of negative display

Fast Response LCD Module at Low Temperature Operation

The response time of LCD at low temperature, say -40¢XC, could be more than 1 minute. This could be a big problem in display application.

With special technique, the response time of our LCD module at low temperature can be as fast as at room temperature.

Film LCD

Film LCD is an ultra thin display (thickness is less than 1mm). A transparent plastic sheet is used as substrate that makes the film LCD be thinner and lighter than the conventional LCD glass panels. Film LCD features a substrate of flexible plastic which allow the display to be bent. The applications of handheld products such as watch , smart card or curve surface products can take the advantages of thin, light and flexibility of film LCD. In this stage, Clover focuses on small panel size(1"~4") and TN mode only.

Shaped LCD

  • Cut corner or angle & round shaped
  • Hole drilling technique at display

Touch panel

  • Analog resistive or digital resistive type

  • Capacitive touch sensor is much more durable than mechanical and membrane switches. This has become the new standard for solid-state switching. The touch sensor IC is used to detect near-proximity or touch on. It allows electrodes to project independent sense fields through any dielectric such as glass or plastic. This capability coupled with its continuous self-calibration feature can lead to entirely new product concepts, adding high value to product design.
  • Capacitive multi-touch panel
    When turn on the touch panel, it would be a balance state. The finger like a cap and couple the signal. After the data processing, the location can be calculated. More than one coordinate can be detected at the same time. So call ¡§multi-touch¡¨. There is no mechanical movement on panel.


  • SSCT display¡¦s image is retentive after the power is removed.
  • It has an excellent readability and wide view angle under the daylight environment.
