AVATEC Creates New Technology for MLCC
Etching/ITO Coating Business
According to the lightweight and thin display trend, the slimming technology is applied to overall mobile displays such as smartphone, ultra-book, tablet PC, etc. applied with thin and high quality panel by applying the chemical etching technology to the display panels such as LCD and OLED and the range of device is being expanded gradually.
AVATEC possesses the best slimming/ ITO coating technology and promise you to provide the high quality and mass-production service by incorporating the ITO coating to remove the static electricity from the panel after slimming process into the process line.
- Slimming process technology: As a essential technology to implement the lightweight and thin LCD panel, it makes the LCD panel (C/F filter + TFT Glass) from the thickness of 1.0mm to the thickness 0.3mm or less
- IMITO & Metal Coating: Is the essential technology for IPS panel to form the pattern to improve the IPS panel touch
We are applying the advanced process technology to the panel to maintain the film uniformity, light penetrability and color reproducibility of the panel after etching through large area etching equipment

Etching Panel Specification
|Product Specification||X-bar Control Line Control Specification||R-Control Line Control Specification|
|5G Glass or under||10 ± 18㎛||20㎛ (0.00%)|
|5G Glass or under||10 ± 20㎛||30㎛ (0.00%)|
Since the display may malfunction by the static on the slimmed panel, the static elimination technology is applied through the vacuum deposition of transparent conductive film (ITO) on the panel.
