0.91" OLED suitable for wearable device ( Wearable Displays )

The 0.91 inch is one of the most popular sizes of COG OLED for wearable displays which received 2017 Taiwan Excellence Award. Winstar Graphic COG 128x32 OLED items no. WEO012832D is built-in with SSD1306 IC, it communicates via 4-wire serial SPI interface only. This controller's built-in voltage generation only need a single 3V power supply is needed. These COG 0.91 OLED modules are ultra thin, lightweight and low power consumption which is great for handheld instruments, meters, smart grid, wearable device, E-cigarette, MP3, IoT, etc. One of the significant advantages of COG structure is the FPC usually is bendable comparing to TAB OLED since the FPC is flexible and there is no chip on the PFC. Therefore, the customers have less limitation to design the displays on their applications.
