The WEX025664B series consists of four 3.12-inch OLED displays of 256x64 px resolution, which differ in the diodes' color, so in the color of the presented content. It can be white (WEX025664BWPP3N00000), yellow (WEX025664BLPP3N00000), green (WEX025664BGPP3N00000), or blue (WEX025664BSPP3N00000).

OLED displays are particularly well thought of due to the excellent readability of presented content obtained by, e.g., extended contrast ratio, which for WEX025664B series has been estimated as 2000:1; simultaneously, it is not dependent on other factors such as, e.g., the intensity of ambient light. OLED displays consist of diodes, a source of light on their own, so there is no need to use backlight, yielding reduced dimensions and weight of modules. That is why they are commonly used in wearables, e.g., smartwatches (whereby the describes models probably will not be a perfect choice for this kind of gadgets; in wearables, you can use, e.g., 0.66-inch WEO006448A, 0.96-inch WEO012864D, or 1.28-inch WEO012864L, worth noticing are also 1.18-inch circular WEO128128B). The undeniable asset of all OLED displays is the wide temperature range. The WEX025664B series can operate in low (-40°C) and high (80°C) temperatures so that they can be profitably applied in both indoor and outdoor applications.
