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
