Optical Clear Resin (OCR) process is a widely used technology in touch screen manufacturing. OCR is a transparent resin material with excellent optical and mechanical properties. Its application in touch screen mainly includes overlay layer and backlight module.
Overlay application:
The OCR process is used to make the overlay of the touch screen, providing protection and transparency. Due to its excellent optical transparency, scratch resistance and chemical resistance, the OCR can effectively protect the touch screen panel from contamination and scratches. In addition, the OCR also has an excellent refractive index and light transmission, which can ensure high definition and good visual effects of the touch screen display.
Backlight module application:
The OCR process can also be used in the backlight module of the touch screen. The backlight module is a key component in providing brightness and uniformity of the touch screen display. By using OCR material as the light guide of the backlight module, higher light transmittance and more uniform light distribution can be achieved. This can improve the brightness, contrast and color brightness of the touch screen display, while reducing energy consumption.
The OCR process offers the following advantages in touch screen manufacturing:
Optical transparency: OCR materials have excellent optical properties, which can achieve high light transmittance and low scattering rate, ensuring the clarity and brightness of the touch screen display.
Mechanical properties: OCR material has high hardness and scratch resistance, which can effectively protect the touch screen panel from damage by external objects.
Chemical stability: OCR materials have strong resistance to common chemicals and can prevent the touch screen from being contaminated and corroded.
Environmentally sustainable: The resin materials used in the OCR process are usually environmentally friendly and meet the requirements of modern manufacturing for green production.
In summary, the Optical Clear Resin (OCR) process plays a key role in touch screen manufacturing, improving the visual appearance, durability and reliability of the touch screen by providing a highly transparent overlay and backlight module. As the technology develops further, the OCR process will continue to drive innovation and progress in the touch screen industry.
