T60: Display inverter XGA vs. SXGA+/UXGA
Posted: Sat Apr 16, 2011 10:40 am
Hi,
the HMM specifies different display inverters for XGA and SXGA+/UXGA on a T60 15": 42T0077 vs. 42T0079.
Does anyone know the reason? I looked into the datasheets of a Samsung LTN150XG-L08 (FRU 13N7065, XGA) and a Boe-Hydis HV150UX1-100 (UXGA). Backlight current is 0.5 mA(rms) higher with the UXGA, typical power consumption is 0.14W more. Is this the only reason and has anyone used a 42T0077 with SXGA+/UXGA?
Any chance that breaking the inverter may also harm the CCFL (by undervolting or leaving the specified frequency range)?
