Описание
Winstar OLED WEO128128B – это круглые 1.18” OLED дисплеи с пассивной матрицей и разрешением 128x128 пикселей. Габариты модуля WEO128128B составляют 37.18×41.23×2.05 mm и Активной Областью в Ø30 mm. OLED дисплей имеет встроенный SSD1327ZB контроллер IC , с возможностью работы в 6800/8080 8-бит паралельной, I2C и 4-х жильной SPI интерфейсах. Ультратонкий дисплей имеет COG структуру и не нуждается в подсветке, за счет чего имеет легкий вес и низкое энергопотребление. Круглые WEO128128B 1.18” OLED дисплеи идеально подходит для портативных приборов, носимых устройств и т.д. В настоящее время доступны 3 цвета: белый, желтый и
небесно-голубой. Рабочая температура модуля: -40℃ до +80℃, с температурой хранения -40℃ to +85℃.

Технические характеристики
Функции контроллера контактного интерфейса
| No. | Символы | Описание | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | VSS | Ground pin. It must be connected to external ground. | ||||||||||
| 2 | VCC | Power supply for panel driving voltage. This is also the most positive power voltage supply pin. It is supplied by external high voltage source. | ||||||||||
| 3 | VCOMH | COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. No external power supply is allowed to connect to this pin. |
||||||||||
| 4 | VCI | Low voltage power supply and power supply for interface logic level. It should match with the MCU interface voltage level and must be connected to external source. VCI must always set to be equivalent to or higher than VDD. |
||||||||||
| 5 | VDD | Power supply pin for core logic operation. VDD can be supplied externally (within the range of 2.4V to 2.6V) or regulated Internally from VCI. A capacitor should be connected between VDD and VSS under all circumstances. |
||||||||||
| 6 | BS1 |
MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS2 and BS1 are pin select.
|
||||||||||
| 7 | BS2 | |||||||||||
| 8 | VSS | Ground pin. It must be connected to external ground. | ||||||||||
| 9 | IREF | This pin is the segment output current reference pin | ||||||||||
| 10 | CS# | This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW). |
||||||||||
| 11 | RES# | This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin pull HIGH during normal operation. |
||||||||||
| 12 | D/C | This pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data. When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register. In I2C mode, this pin acts as SA0 for slave address selection. When 3-wire serial interface is selected, this pin must be connected to VSS. |
||||||||||
| 13 | W/R# | This pin is read / write control input pin connecting to the MCU interface. When 6800 interface mode is selected, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH and write mode when LOW. When 8080 interface mode is selected, this pin will be the Write (WR#) input. Data write operation is initiated when this pin is pulled LOW and the chip is selected. |
||||||||||
| 14 | RD# | This pin is MCU interface input. When 6800 interface mode is selected, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled HIGH and the chip is selected. When 8080 interface mode is selected, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected. When serial or I2C interface is selected, this pin must be connected to VSS. |
||||||||||
| 15 | D0 | These pins are bi-directional data bus connecting to the MCU data bus. Unused pins are recommended to tie LOW. When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SDIN and D2 should be kept NC. When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL. |
