Lenovo ThinkPads are a commonly used laptop in personal computing. Like all mobile products, however, screens can sometimes become damaged or cracked. If you need to repair or replace the LCD screen on your Lenovo ThinkPad, here are some answers to some commonly asked questions.How do you choose the right screen?

In order to get the right replacement screen for your ThinkPad, you will need to know the model number. Depending on when your ThinkPad was manufactured, there are several ways to find the model number. On some ThinkPads, the model number will be printed directly onto the bezel (case) below the LCD screen. On most laptops, the machine type (model number) will also be printed on a label on the bottom of the laptop. If the label is missing, damaged, or illegible, there are still a few other ways to find that information. Here are some other ways to find the model information for your ThinkPad:Check under BIOS.

Many LCD displays are actually comprised of two different parts: the LCD itself and a glass cover. In some cases, the LCD screen itself is fine; it is just the glass cover that needs to be replaced. In other cases, the entire LCD display needs to be replaced. If just the glass cover needs to be replaced, keep in mind that the LCD screen itself can still become damaged while replacing the glass cover. When ordering a replacement screen, it is important to make sure you know what you are getting. Some offers are for the glass cover by itself, some are for just the LCD screen and glass, and others are for the entire top half of the laptop, including the LCD, glass, and outer case. In many cases, replacing the entire top half of the laptop can be simpler and less time-consuming than replacing the LCD or glass. Replacing the entire top half of the laptop also generally requires less technical capability.Can screens be upgraded?

Many parts on Lenovo products can be upgraded to improve a ThinkPad"s speed or performance, but a screen is not one of them. Each screen is specifically manufactured and calibrated for a specific Lenovo product. Each product also needs specific drivers to operate specific screens as well. Though the size of a screen may be exactly the same from one Lenovo product to another, they are not interchangeable. You need to be sure, when ordering a replacement part, that you are ordering a part specifically designed for your model of ThinkPad. For example, if it is designed for a 14-inch screen, you need to order one exactly that size.

you don"t say what LCD? Old Nokia one with SPI communication? Modern TFT with MIPI DSI? I8080-compatible (like HD44780), or LCD with parallel RGB interface?

You can start with these questions and as soon as you answer them, download ST MCU Finder and choose the family (performance, frequency), package (64 or 100 pins?) and peripherals (I2C, LTDC, MIPI DSI, SPI, JPEG).
