【 摘 要 】

Aim is to study the features of gamma correction of full-color active-matrix OLED microdisplays in a wide dynamic range of brightness. Methodology. The study was carried out by calculation and experimental methods by modeling color coordinates of OLED electroluminescence at different luminance and accounts RGB color filters transmission spectra. The modeling based on experimental data obtained by measuring the electrical, photometric and spectral characteristics of OLED samples and the transmission spectra of RGB color filters. Results. Introduced base construction of full color active-matrix OLED microdisplays and method of forming color image by filter matrix. Electrical, photometrical and spectral characteristics of initial white OLED structures was represented as well as modeling of RGB color separation and factors affecting color balance of full color image. The features of full color OLED microdisplay gamma correction for different luminance level and temperatures are considered. Research implications. Researches have practical relevance for OLED microdisplays design and calibration in production stage.
