In fairness, LCD panel makers have done a lot to close the gap with CRTs. "The faster something moves across the panel, the less capable an LCD is with keeping up with the movement."
"The issue here is that you're comparing an electronic conversion-that is, from an electron to a photon-with physically twisting the liquid crystal," Young said. This may explain why Digital Foundry's John Linneman described the CRT experience as "cleaner, smoother, nicer" compared to even the best LCDs. Raymond Soneira, the president of display research firm DisplayMate, has found that this issue even persists on panels with faster refresh rates than the usual 60 Hz. It also creates blurriness when there's a lot of motion happening across the screen. Applying voltage to each crystal causes them to twist, altering the amount of light that comes through the screen's front polarizer.Ĭompared to electron-photon conversion, the physical movement of liquid crystals inside an LCD display takes a lot more time, introducing input lag. On an LCD, the back of the display emits a constant stream of white light, which passes through a polarizer and onto an array of liquid crystals. "You hit it with an electron, and it creates a photon immediately."īy contrast, an LCD requires physical movement on the part of every pixel. "It's the chemistry of the phosphors," said Barry Young, a longtime CRT display analyst who is now the CEO of the OLED Association.
