A 1.8-inch 200-ppi full color active matrix micro light emitting diode (LED) display prototype has been developed with a low-temperature-poly-silicon (LTPS) TFT backplane. The frame rate of 240Hz and the luminance of 2000nits, both of which are promising attributes for high motion image quality and high dynamic range (HDR) applications, being superior to existing display technologies, were achieved by our LTPS TFT technology.
