More Than Just an Display Manufacturer

Superior in-house production ensures quality and efficiency, unlike small factories with higher defect rates.

Small Factories

Small factories often outsource production, leading to unreliable delivery and quality. A common issue is the use of off-cut materials for polarizers.

Our Advantages

We boast in-house production lines with strict quality control, ensuring superior quality and higher efficiency. We use original, standard materials for reliability.

Small Factories

Outsourced bonding leads to electro-corrosion in small factories. Without secondary and tertiary cleaning, the defect rate increases, leading to unstable delivery schedules and uncertain quality.

Our Advantages

Our self-operated production lines ensure superior quality and higher efficiency.

Small Factories

Irregular aging processes in small factories result in high defect rates and frequent product failures.

Our Advantages

Our facility includes aging rooms and plug-in wiring products, guaranteeing over 8 hours of aging for every unit.
