 Metal Oxide TFT Display
Metal Oxide TFT has feature of high mobility (~10 cm2/V-sec) and high on current, is suitable for AMOLED and High-end LCD product. CPT develop solution type process and Demux drive technology on Metal Oxide TFT display. Solution metal oxide has cost advantage by Non-Vacuum process. Dumux (Source & Gate) drive not only can maintain the advantages of energy saving and high brightness , but also can reduce the number of IC and border size. These two technology can make the CPTs product more competitive in the future.

 Flexible AMOLED Technology
Wearable device is one of the most important display applications. Flexible AMOLED is the most suitable and potential technology for wearable devices. CPT develops Thin Film Encapsulation and high temperature resist & transparent plastic substrate technology applying to Flexible AMOLED, which can absorb the bending stress to prevent OLED display from mechanical damage.
  • Flexible Display
  • High Barrier Encapsualtion
  • Foldable (R~3mm)

Colorful transparent LCD
CPT has developed polarizer-free liquid crystal technology with RGBW pixel design on Colorful transparent display. It can show clear image via ambient light. This technology not only can maintain the advantages of high transmittance and high image quality, but also can reduce power output. It can make the product more competitive. This technology can be applied in many kinds of the products such as mobile display, demonstration kit or car-use head-up display.
  • High transmittance (>25%)
  • low driving voltage (~5V)
  • Power saving (Green Product)
  • High image quality

Colorful Dynamic E-paper Technology
CPT has developed polarizer-free liquid crystal technology with Reflective panel design on Colorful dynamic e-paper display. It can show clear image with ambient light. This technology not only can maintain the advantages of high Reflectivity and high image quality, but also can reduce power output. It can make the product more competitive. This technology can be applied in many kinds of the products such as Colorful dynamic e-paper display or Electronic signage.
  • High reflectivity(>20%)
  • low driving voltage (~3.5V)
  • High frame rate (60Hz)
  • Full-color image
Touch in Cell Technology
The structure of Touch in cell is integrated the touch sensor and TFT Array in display. CPT combined Touch in cell with TDDI (Touch Display Driver Integration) IC technology and provided thinnest and simply touch module for our customer. This technology can apply in smart phone and tablet product.

 ToC with passive stylus Technology
CPT implement passive stylus technology in ToC (Touch on Cell) panel to support hand touch and pencil writing. The difference is the passive stylus is any arbitrary pencil compared with active stylus. CPT alreday developed ToC with passive stylus and will be applied in education tablet product.

Glass LGP Display Module
Compared with conventional light guide plate and guide plate glass, glass in addition to the light guide plate itself has good dimensional stability and strength than the conventional module can achieve thinner, in order to enhance the product features and reliability.
  • Thinner LCM module
  • Dimensionally stable and strong material strength
  • Improve product features and reliability verification

Smart Watch Display
CPT demonstrated the wearable technology about 2-in. full-circle display by using a-Si(Amorphous Silicon). High resolution (480xRGBx480, 240PPI) and GIP circuits design is the characteristic in this display. The results of optical verification and reliability test show this 2-in. full-circle display has good performance.
  • Full-circle active area
  • High resolution and GIP (Gate in Panel) circuits design in
  • Lower cost by using a-Si (Amorphous Silicon) process

 High-Efficacy OLED Lighting Technology
OLED(Organic Light Emitting Diode) is a surface light source and has advatages like thin, lightweight, uniform and flexibility. Its expected become a major source of next-generation solid state lighting. Developed OLED lighting by CPT is a green product(Thin, fast reponse, low driving voltage, and no mercury) and meets the requirements of the next generation of lighting conditions for better life in the future.
  • Low Power Comsumption---Without Backlight Unit
  • Natural Color Resembling Sunlight---High CRI
  • Uniform Llight Source---No Glare and Eye Strain
  • Ideal Solid State Lighting---No heat and Ultraviolet
