Deep Controllable Backlight Dimming for HDR Displays [PDF]
IEEE Transactions on Consumer Electronics, 2022 High dynamic range (HDR) displays with dualpanels are one type of displays that can provide HDR content. These are composed of a white backlight panel and a colour LCD panel. Local dimming algorithms are used to control the backlight panel in order to reproduce content with high dynamic range and contrast at a high fidelity.

A Generalized Dimming Control Scheme for Visible Light Communications [PDF]
IEEE Transactions on Communications, 2021 A novel dimming control scheme, termed as generalized dimming control (GDC), is proposed for visible light communication (VLC) systems. The proposed GDC scheme achieves dimming control by simultaneously adjusting the intensity of transmitted symbols and the number of active elements in a space-time matrix.
