What is an OLED display?

An OLED display uses a relatively new technology called OLED (Organic Light Emitting Diodes). OLED displays are brighter, more efficient, thinner and feature better refresh rates and contrast than other display technologies.

OLEDs are made by placing thin films of organic (carbon based) materials between two electrodes. When an electrical current is applied, a bright light is emitted. Since the OLED materials emit light, a backlight is not required (unlike LCDs).



OLEDs for digital cameras

OLED-equipped cameras are offered by some of the biggest names in the industry. OLEDs’ major advantages seem to be especially beneficial for digital cameras - a wide color scheme, superior contrast, high refresh rates and more.

OLEDs are mostly prevalent in compact cameras, but the technology is also starting to appear in DSLRs and high-end models. OLED displays are used in digital cameras as back displays and also as viewfinders.

All OLED camera back displays use AMOLED screens. The OLED electronic viewfinders (EVF) use OLED microdisplays - tiny high resolution displays (under 1-inch) that are magnified to be used as a near-eye display.
