What is Optical Bonding?

Optical bonding is a technology that uses optical-grade adhesive (OCR or OCA) to bond the display glass or touch panel directly to the TFT LCD panel, forming a solid laminate without any air gap or bubbles.

It is widely used in medical, military, transportation, retail and outdoor applications where high brightness, durability and reliability are required.

Optical Bonding Process

Our optical bonding technology improves optical performance, impact resistance and thermal management.

1. TP / LCM Inspection

LCM Inspection

a. Check for foreign objects or scratches on the screen

b. Ensure the metal frame is intact and undamaged

c. Check for dead pixels, dark spots and color abnormalities

TP Inspection

a. Inspect surface scratches and flex cable condition

b. Verify touch functionality

2. LCM Sealing Dam

1. Apply black adhesive around the edges to prevent leakage during injection.

2. Cure the adhesive in an oven.

3. Remove Excess Adhesive

Clear any excess black adhesive from the frame.

4. Inject Wacker Sealant

Ensure no air bubbles are formed during the process.

5. Seal Edges with Black Adhesive

Enhance waterproofing and reinforce the injected sealant layer.
