Frequently Asked Questions

Can small-sized LCD screens be equipped with touch functions?

Yes, touch functionality is commonly available. Options include:

Resistive Touch: Cost-effective, works with any object, resistant to contaminants. Lower transmittance and typically no multi-touch support.
Capacitive Touch: High transmittance, sensitive touch response, supports multi-touch, durable glass surface. Requires finger or special stylus input.

How long is the lifespan of a small-sized LCD screen?

Display lifetime consists of two components:

Backlight Lifetime: LED backlights typically last 30,000 to 70,000 hours (approximately 3.5 to 8 years of continuous use). High temperatures can reduce lifespan.
LCD Panel Lifetime: Typically exceeds 50,000 hours under normal operating conditions. Avoid physical shock, extreme temperatures, and excessive humidity.

How long does it usually take for a sample?

Samples are typically dispatched within 3 to 5 business days.

How long is the delivery cycle generally?

Standard delivery time is 20 to 30 days from order confirmation.
