近年来，人们对使用有机发光二极管（OLED）用于室内环境中的照明越来越感兴趣。它们提供了有吸引力的功能，如灵活性和低成本的大有效面积;与硅基LED相比，它们是节能的，并且具有更高的照明水平。此外，由于OLED的低厚度，OLED在诸如智能移动的电话和TV的装置中的利用率已经增加。本文研究了基于OLED的可见光通信（OVLC）系统的性能，使用弯曲和平坦的OLED与多波段无载波幅度和相位（m-CAP）调制，m = 2，在不同的入射角的光接收机。结果表明，BER性能得到了改善（即，低于3.8×10 - 3的前向纠错（FEC）极限），这在设备到设备通信中是有利的。
In recent years there has been a growing interest in using organic light emitting diodes (OLEDs) for illumination in indoor environments. They offer attractive features such as flexibility and large active areas at a low cost; they are energy efficient and have higher illumination levels compared to silicone based LEDs. In addition, the utilization of OLEDs have increased in devices such as smart mobile phones and TVs because of their low thickness. This paper investigates the performance of an OLED based visible light communications (OVLC) system, using a curved and flat OLED with multiband carrierless amplitude and phase (m-CAP) modulation for m = 2 at different angles of incidence on the optical receiver. It is shown that the BER performance is improved (i.e., below the forward error correction (FEC) limit of 3.8×10−3) with the curved OLED when the optical receiver moving along a circular path for the viewing angles greater 40° compared to the flat OLED, which is advantageous in device to device communications.
