Sheldon’s TV Test Pattern Shirt
Filed under: TV Series, The Big Bang Theory, Jim Parsons, Sheldon Cooper
On this light blue t-shirt is a television test pattern; also known as a text card. Others might call, what is on this shirt, TV color bars or SMPTE color bars. I am sure most people in North America have seen these color bars on their TV screens at one point or another, accompanied by a 1khz sine wave audio signal.
