FAQ

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

Yes. This is a very common requirement. The touch panel is typically laminated onto the surface of the LCD. Main types:

Resistive Touch: Low cost, resistant to surface contaminants (dust, water), works with any object. Lower transmittance, relatively less durable (scratches), usually no multi-touch.

Capacitive Touch: High transmittance, sensitive and smooth touch, supports multi-touch, durable (glass surface). Higher cost, requires finger or special stylus, sensitive to water/oil on surface.

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

Lifetime primarily refers to the Backlight lifespan (usually measured in hours until brightness drops to 50% of initial) and the reliability of the LCD Panel itself.

Backlight Lifetime: Common LED backlights typically last 30,000 to 70,000 hours (approx. 3.5 to 8 years of continuous use). High temperatures significantly reduce this.

LCD Panel Lifetime: Generally very long, often 50,000 hours or more under normal operating conditions (avoiding physical shock, extreme temperatures, excessive humidity). The screen itself typically does not suffer from "burn-in".

3.How long does it usually take for a sample?

Samples usually take 3 to 5 days to be dispatched

4.How long is the delivery cycle generally?

The delivery time is within 20 to 30 days
