IPS DISPLAY PANELS AND FHD (1920×1080) DISPLAY MODIFICATION
Non-tablet models of the X220 and X230 shipped with either a standard 12.5-inch “TN” TFT display or a 12.5-inch extra bright wide-viewing “IPS” TFT display with 1366×768 resolution.
The IPS display is generally considered the far superior option providing a brighter image, higher contrast and much better viewing angles than the TN display. Video demonstration
Five versions of the 1366×768 IPS display panel are available:
- LP125WH2(SL)(B1) – the B1 IPS panels sometimes have issues with image retention or “ghosting” after a static image has been on the display. Some users have also reported a backlight bleeding issue with these panels.
Manufacturer part number: 0A66673
FRU: 04W3462, 93P5674, 93P5675
- LP125WH2(SL)(B2) – the B2 IPS panels do not tend to have issues with ghosting or backlight bleeding however they do not have the mounting rails on the sides needed to install properly in an X220.
