Type: article
Abstract: Single-side-emitting LED displays have been widely utilized in various applications, but they have inherent limitations when it comes to scenarios requiring display content on both sides simultaneously. In this work, a double-side-emitting LED display has been demonstrated employing all-in-one packaged devices as the pixels. The impacts of time-division multiplexing (TDM) driving configurations on the temperature and chromatic characteristics of the displays have been investigated, demonstrating that TDM can efficiently increase the light output of the red emission of double-side-emitting LED displays and also enlarge the color gamut by reducing the temperature. The reduction in temperature of 6.2 K and the increase in luminance of 173.5 cd/m2have been achieved for double-side-emitting LED displays.
