An active-matrix mini-LED backlight unit with 2,304 dimming zones and 16-bit gray levels for 85-inch ultra-high-definition LCDs has been demonstrated, in which single X-wire completes line addressing, dimming data transmission and voltage feedback for multiple dimmers on one wire. Thus, the system with an easily expandable layout can achieve high contrast ratio and low power consumption.
