Winstar Launches New Circular OLED

OLED's or Organic Light Emitting Diodes, are an offshoot of existing conventional LED technology. LEDs are semiconducting light sources that function through electroluminescence.

OLEDs on the other hand, use use a series of thin, light emitting films. This allows the OLED array to produce brighter light while using less energy than existing LCD/LED technologies. Because these light-emitting films are composed of hydrocarbon chains rather than semiconductors laden with heavy metals like gallium arsenide phosphide, they are considered organic, hence the "O" in their name.

Winstar has just launched its first circular passive matrix OLED display, the WEO128128B. This new OLED is made up of 128x128 dots with a diameter of 1.18 inch. Its module dimension is 36.98× 41.23 × 2.05 mm with an active area size of 30.00×30.00 mm. It is built in with a SSD1327ZB controller IC and it communicates via 6800/8080 8-bit parallel, I2C and 4-wire SP
I serial interface, 3V power supply.

The WEO128128B is a COG structure OLED display which is ultra thin and no need of backlight (self emitting). The product is lightweight and low in power consumption.


This Circular OLED module is ideal for:

  • Portable instruments
  • Wearable devices
  • Home applications
  • The standard emitting colors for the WEO128128B are white, yellow and sky blue, the operating temperature is -40℃ to +80℃, and the storage temperatures is -40℃ to +80℃.
