Field Sequential Color 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.

Capacitive Touch

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.

Color TN LCD

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.

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.

Fast Response LCD Module at Low Temperature Operation

The response time of LCD at low temperature, say -40°C, 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.
