IPS DISPLAY PANELS
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. Both varieties have a native resolution of 1366 x 768.
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 x 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 are less likely 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.
- LP125WH2(SL)(B3) – the B3 IPS panels are less likely to have issues with ghosting or backlight bleeding and include the necessary side mounting rails for installation in the X220. (Recommended)
Manufacturer part number: 0A66702
- LP125WH2(SL)(T1) – the T1 IPS panels were not originally installed in the ThinkPad X220 but are completely compatible and include the necessary side mounting rails. (Recommended)
Manufacturer part number: 0A66690
- LP125WH2(SL)(T2) – the T2 IPS panels do not have mounting rails that align properly with the X220.
Note: When purchasing a LCD panel we recommend contacting the seller first to verify the part number of the unit they will be sending. Many merchants will advertise a particular part number but send a “compatible part” instead.
