Electronics

Optical color pigments have many applications in the electronics industry, mainly in the following aspects:

Display field

• OLED display: The organic dyes or luminescent polymers used in OLED can emit light under the action of an electric field, achieving high brightness, wide color gamut, and low power consumption. They are widely used in mobile phones, TVs and other display devices.

• QLED display: Using quantum dot materials as pigments, it has the advantages of high brightness, high color gamut, and high efficiency. It is one of the important development directions of the next generation of display technology and can be used in high-end displays and TVs.

• Electronic paper: Electronic paper using pigments as display materials, such as electronic ink screens, has the advantages of good flexibility, low power consumption, and large viewing angles. It is suitable for e-books, electronic tags and other fields.

Appearance decoration

• Product shell: Optical color pigments can make the shell of electronic products change color according to environmental conditions and user behavior, increasing the fun and personalization of the product. For example, some brands of mobile phones, laptops and tablets have begun to use this pigment in their shells, bringing users a unique visual enjoyment.

• Internal component identification and decoration: Using color-changing pigments in audio devices such as wristbands, function buttons, headphones, microphones, etc. can make the product appearance more beautiful, fashionable, and unique, and enhance the overall quality and attractiveness of the product.

Sensor field

• Optical sensor: Some optical color-changing pigments have sensitive response characteristics to light of specific wavelengths, and can be used to manufacture optical sensors to detect changes in physical quantities such as light intensity, color, and temperature, thereby realizing functions such as environmental monitoring and biomedical testing.

• Pressure sensor: By combining optical color-changing pigments with pressure-sensitive materials, pressure sensors that can change color according to pressure changes can be manufactured, which can be used in electronic equipment buttons, touch screens and other components to achieve a more intuitive and convenient operation experience.

Anti-counterfeiting and security field

• Product anti-counterfeiting: Optical color-changing pigments have unique optical properties and color-changing effects, and can be used to manufacture anti-counterfeiting logos for electronic products, which are difficult to copy and forge, and improve the safety and credibility of products.

• Information encryption and security: In the process of electronic information storage and transmission, the special optical properties of optical color-changing pigments can be used to encrypt and decrypt information to ensure the security and confidentiality of information.
