What is this close-up picture? (WotsThat: LCD screen pixels (macro))

Question

What object is shown in this zoomed-in close-up photo?

BogIron · Accepted Answer

LCD screen pixels (macro). Your LCD screen is constantly flickering thousands of times per second, but your eyes blend these rapid color changes together so smoothly that you perceive solid colors—meaning what looks like a stable red pixel is actually red, green, and blue subpixels rapidly cycling in different intensities. This is why old CRT monitors could give people headaches at lower refresh rates, but modern LCDs at 60Hz and up feel perfectly smooth to our brains.
