Lenovo Thinkvantage Toolbox Windows 7 32 Bit WORK Download
service parts -307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-77027 (it says WXGA+ 1440x900 HD, but that is not available for T420s, assume it is typo, the product description on driver download has the same error, fixed recently) 3 possible FRU - 93P5693 (forum post said AU Optronics B140RW02 V1), 93P5689 (forum post said LG, also ID as LGD02E2), 93P5685 (?). Not sure which one is LEN40A1 until we take one apart and/or wait for SN cross check in parts database. HWiNFO32 v3.73-1200 said it is (LG-Philips WXGA++/HD+) LP140WD2-TLB1 17cmx31cm, Gamma 2,20 101.60 MHz pixel clock. B140RW02 V1 is not any better, its surface seem to be not smooth, not sure it is the AR coating or not, like looking through textured soft focus filter.
