The brightness of EL based backlights can not compete with daylight, CCFL or LED, of course. But the target application can be found in twilight and darkness. E.g. displays of music machines and handheld computers, controls and instruments, signaling, clocks, etc.
A great advantage is the small power consumption and the flexibility of the paperthin material.
