OUTLINE DIMENTION
FAQ
1.Are Amotec LCDs RoHS compliant?
Yes, all Amotec LCDs are RoHS compliant.
2.Are UL certifications available for Hantronix LCDs?
The complete LCD display module does not require UL certification, however, certain components such as PCB and backlight wires are UL certified.
3.What is the difference between a Digital TFT and a Analog TFT?
The difference is the interface signal. The digital TFT is designed to accept digital interface signals TTL / LVDS. The analog TFT is designed to accept analog RGB / NTSC / PAL interface signals.
4.What is the lifetime spec for a Amotec LCD backlight?
The lifetime (50% of original backlight brightness) for White LED backlight is rated as high as 40K hours. The lifetime for CCFL backlight is rated as high as 40K hours. (Please refer individual specification for more details.)
