To understand why the $450 billion semiconductor industry has lurched into crisis, a helpful place to start is a one-dollar part called a display driver.
Hundreds of different kinds of chips make up the global silicon industry, with the flashiest ones from Qualcomm Inc. and Intel Corp. going for $100 apiece to more than $1,000. Those run powerful computers or the shiny smartphone in your pocket. A display driver is mundane by contrast: Its sole purpose is to convey basic instructions for illuminating the screen on your phone, monitor or navigation system.
The trouble for the chip industry — and increasingly companies beyond tech, like automakers — is that there aren’t enough display drivers to go around. Firms that make them can’t keep up with surging demand so prices are spiking. That’s contributing to short supplies and increasing costs for liquid crystal display panels, essential components for making televisions and laptops, as well as cars, airplanes and high-end refrigerators.
