Our Business

One of our origins as the world's leading colorant company is our synthesis technology of organic pigments.
Also, the nano-level dispersion technology that we have accumulated through our years of developing inks and paints are now being applied to the products in the display enterprise such as liquid-crystal displays and image sensors.
TOYO Visual Solutions is in charge of expanding the display material business of the TOYO INK Group worldwide.

Color Filter Materials for FPDs

The color filter, which can be found in flat panel display (FPD) products such as TVs, computers, and smartphones, is the key component in color reproduction. Recently, color filters are being used not only in liquid crystal displays, but also in other panel appliances such as e-papers and OLEDs.
The FPD-specialized color filter materials are our leading-edge products that inherit the nano-level dispersion technology the Toyo Ink Group has fostered through its history of ink and paint development. As a result, we have achieved a high market share around the globe.
With the advantage of being able to develop and produce high-performance pigments to resist inks, we will continue to offer a visual solution for the improvement of color displays.

On chip Color Resist for Image Sensors

The image sensor is a semiconductor that converts the brightness of the light that enters the camera lens into electric signals. It has the same function of the retina in the human eye. By converting the light into electric signals, we are able to reproduce the light as images or videos.
There are mainly two types of image sensors, CMOS and CCD. In the past, the two types of sensors were used in different applications according to their characteristics. CCD sensors, which have excellent image quality and little distortion, were often used for digital single-lens reflex cameras. On the other hand, CMOS sensors which have smaller power consumption and are easy to miniaturize, were often used for mobile phones and compact digital cameras.
Nowadays, CMOS sensors that match the image quality of CCD sensors have been developed, so most cameras and smartphones now adopt the CMOS sensors.

Optical Materials

Infrared rays (IR) have longer wavelengths compared to visible light, making these waves invisible to the human eye. Being invisible, IR is useful in optical appliances such as infrared cameras, TVs, and remote controllers. Furthermore, the use of IR is expected to play a major role in the sensors for upcoming technology such as autonomous driving and biometric authentication. These advanced sensors will need materials that can block/transmit these wavelengths according to their application. We will contribute to the development of these sensor technologies by delivering such IR optical materials to our customers.
