TRANSFLECTIVE DISPLAY HAVING FULL COLOR OLED BACKLIGHT

摘要

Disclosed is a conventional 0rganic light emitting diode (OLED)(156) having one reflective electrode in combination with a least one transparent OLED in stacked configuration functioning as backlighting in a transflective display apparatus such as a liquid crystal display (LCD) (180). Preferably, at least two transparent OLEDs (154,152) are arranged in a stacked configuration with one conventio -nal OLED (156), each of the tree OLEDs emitting light of a different bandwidth (161N,161G,161B). The reflective electrode (117) located behind the backlight also serves as a reflecting plate for the display. This arrangement enhances reflectivity and permits color sequencing in the transmissive mode, allowing all the components of a full color display (i.e.red, green, blue) to emit through the same pixel without the need for a color filter. ® KIPO & WIPO 2007
