  • Local dimming control with 2-line addressing
    Patent number: 11769460
    Abstract: An image displaying apparatus with local dimming control with 2-line addressing is disclosed. The apparatus includes a display panel, a light-emitting diode (LED) backlight divided into a plurality of zones, and a control unit. The control unit is configured to couple a dimming data to the LED backlight. The zones of the LED backlight are driven by row enable signals and column driving signals based on the dimming data. Each individual column driving signal transmits a common brightness data, a first residual brightness data, and a second residual brightness data. A first row enable signal has a first enable pulse in a frame period, and a second row enable signal has a second enable pulse in the frame period. The first and second enable pulses are at least partially overlapped for reducing a pulse current of the LED backlight for enhancing a lifetime of the LED backlight.
