What is Optical Bonding?
Optical bonding is a technology that injects special glue in the display glass or touch screen and TFT liquid crystal (TFT) panel and coated with a layer of resin (OCR) or film (OCA), bonding into a solid laminate without gaps or bubbles. When selecting screens for any project, you should evaluate the environmental and operational conditions that screens will have to endure. Industrial-grade screen and panel PCs are rugged with all types of features and can withstand any type of application. One property that can be considered is optical bonding.
Optical bonding is widely used in the medical, military, transportation and retail sectors where higher performance displays are required due to harsh environments. Optical bonding is suitable for industries that need to use robust displays in high reliability environments or need to use displays in high ambient light conditions. The optical bonding process is particularly suitable and more efficient for equipment that operates outdoors or in bright light.
LOCA optical lamination fills the organic silicone between the LCD module and the touch screen which the light reflection loss is small. Therefore, the display screen has a higher contrast and superior display effect under the irradiation of ambient light. It effectively avoid condensation, dust or other impurities in the interlayer of the display screen.
Ambient light reflects after it reaches the display screen. The air in the middle of the traditional air gap bonding screen will cause the loss of light reflectivity. The higher the reflection loss, the lower the contrast of the display.
