LG Display has an excellent article on how they build TFT LCD displays. Check it out for a fun and interesting look at how millions of transistors are built up layer by layer to form a finished display:
Ever wondered how the TV and monitor displays you use every day work? The TFT-LCD manufacturing process consists of a set of processes for producing TFT, color filtering, cell, module and others. LG Display Newsroom gives a detailed, but easy to follow explanation of the entire steps below.
Let’s take a closer look at the production process for a TFT board, the bottom-most layer of an LCD panel. The image above depicts a TFT board, which consists of rows of small rectangular sections that together resembles a chessboard. Each rectangular section is a pixel, and each pixel contains a transistor that controls its function. The TFT process is the process that builds these transistors on top of a glass substrate.
