摘要

单面发光LED显示屏已经广泛应用于各种应用中，但是当涉及到需要同时在两侧显示内容的场景时，它们具有固有的局限性。在这项工作中，一个双面发光的LED显示屏已经被证明采用一体化封装器件作为像素。研究了时分复用（TDM）驱动配置对显示屏温度和色特性的影响，表明时分复用可以有效地提高双面发光LED显示屏的红光输出，并通过降低温度来扩大色域。双面发光LED显示屏的温度降低了6.2 K，亮度增加了173.5 cd/m2。

Luminous Properties of Double-Side-Emitting LED Displays Employing All-in-One Devices

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/m² have been achieved for double-side-emitting LED displays.
