LCD CTP Full Lamination

Capacitive Touch Panel Manufacturing Process

We have independent CTP touch production workshop, supporting touch sensor processing, pre-cleaning and mass bonding production. It can match LCD modules of various sizes to realize integrated touch display solutions.

CTP Description

Every CTP panel undergoes microscopic inspection, electrical testing, and final module validation. Our process supports air/OCA / LOCA bonding, delivering industrial-grade touch performance with long-term reliability.
CTP-FOG Automatic Dual-Side ACF Bonding

We start with high-precision CTP-FOG Automatic Dual-Side ACF Bonding using fully automatic CCD-aligned equipment. This step ensures stable electrical connections between the touch sensor and FPC, enabling reliable touch signal transmission.
CTP-FOG Microscopic & Electrical Inspection

After bonding, panels go through Microscopic Inspection to verify bond alignment and quality, followed by CTP-FOG Electrical Testing to validate touch signal integrity, linearity, and noise immunity.
CTP-FOG Single-Line Adhesive Dispensing

single-line adhesive dispensing applies protective epoxy to the bonding area, enhancing mechanical strength and moisture resistance. The process ensures uniform coverage without overflow or bubbles.
Sensor SCA Attachment & SCA Lamination

Structural Conductive Adhesive (SCA) is applied to the touch sensor, followed by SCA Lamination with the LCD/Cover Glass assembly. This creates a rigid, optically clear bond for full-lamination applications.
SCA Defoaming & UV Curing

The laminated assembly enters a vacuum defoaming stage to eliminate micro-bubbles, then undergoes SCA UV Curing to harden the adhesive, ensuring zero light leakage and long-term bonding stability.
