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 include:
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.
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 (approximately 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".
How long does it usually take for a sample?
Samples usually take 3 to 5 days to be dispatched.
We produce portable infusion pumps that need a 2.2-inch dot matrix screen to display flow rates and alarms, where reliability and anti-interference are critical. Your screen delivers complete characters with no missing rows, and shows no flickering when tested near motors and solenoid valves—clinical performance is highly stable, and nurses say readings are very clear.
