Abstract
Abstract Active matrix (AM) mini‐LED backlight units (BLUs) based on amorphous silicon (a‐Si) thin‐film transistor (TFT) on a glass substrate for 75‐inch 8K liquid crystal displays (LCDs) are developed, with each consisting of 5184 local dimming (LD) zones. The 75‐inch 8K LCDs perform a high dynamic contrast ratio of 1,000,000:1 and high typical brightness of more than 1000 nits with 10% capable screen area. In addition, the LCDs show an excellent high dynamic range (HDR) and a real black state, which are comparable to that of other high‐end displays (dual cells and organic light‐emitting diode displays [OLEDs]). Also, the mini‐LED BLUs feature a low fabrication cost.
