Abstract
772e steady-state complex power components were quantitatively analyzed and studied by using an experimental 2×2 active-matrix organic light-emitting display (AMOLED) system and waveform analysis. The experimental AMOLED is configured by using a complex programmable logic device (CPLD) as driving system together with OLED pixels. The profiles of real and virtual powers of OLED load were determined from real-time analysis during panel operation. Our experimental results revealed that the real power of OLED load at lower operation frequency 308 Hz is approximated the same as total power. The virtual power is about 28% of total power at lower operation frequency. The real power of OLED load at higher operation frequency 1262Hz is 1.76 times greater than total power. The virtual power is 2.35 times greater than total power at higher operation frequency.
