- Look at wikipedia for difference between TN and IPS panels. IPS have much better colour/contrast than - a regular TN, and will typically have good viewing angles. -

- These seem to be from the X200 tablet. You need to find one without the glass touchscreen protection on it - (might be able to remove it, though). It also must not have a digitizer on it (again, might be possible to - just simply remove the digitizer). -

- -

- If your X200 has an LED backlit panel in it, then you also need to get an inverter and harness cable - that is compatible with the CCFL panels. To see which panel type you have, see - #led_howtotell. If you need the inverter/cable, here are part numbers: - 44C9909 for CCFL LVDS cable with bluetooth and camera connections, and 42W8009 or 42W8010 for the - inverter. -

- There are glossy and matte versions of these. Matte means anti-glare, which is what you want (in this authors opinion). -

How to tell if it has an LED or CCFL?

- -

- Some X200s have a CCFL backlight and some have an LED backlight, in their LCD panel. This - also means that the inverters will vary, so you must be careful if ever replacing either - the panel and/or inverter. (a CCFL inverter is high-voltage and will destroy an LED backlit panel). -

-

- CCFLs contain mercury. An X200 with a CCFL backlight will (unless it has been changed to an LED, - with the correct inverter. Check with your supplier!) the following: "This product - contains Lithium Ion Battery, Lithium Battery and a lamp which contains mercury; dispose according to - local, state or federal laws" (one with an LED backlit panel will say something different). -
