The OLED emits light from organic materials, so a display backlight is not required. It provides an extremely higher contrast and a very wide viewing angle of almost 180 degrees. In addition, the OLED display is set close to the front panel.
Well laid out characters help identify important information like operating frequencies. White characters on a black background show clear easy to read operating information. With white key backlighting, the white OLED display matches modern plane’s instrument panel.
In addition, the auto dimmer function adjusts the display for optimum brightness at day or night.
The A220’s display has a wide active area, so operating frequencies’ characters can be maximized in the display, while operating status can be shown on both top and bottom.
The A220’s OLED can display 4-level gray scale from darker gray to bright white and increases readability. This gradation is used, for example, in showing selected items in the settings menu.
