Beschreibung
Das WEF012864Q ist ein 2,7“ OLED-Display mit einer Auflösung von 128x64 Pixeln. Dieses Grafikdisplay ist mit dem Controller-IC SSD1309 ausgestattet und unterstützt die 6800/8080 8-Bit-Parallel-, und I2C- /4-Draht-Seriell-Schnittstelle. Es hat eine Modulgröße von 89,7 x 47,2 mm und eine AA-Größe von 61,41 x 30,69 mm. Es hat das gleiche OLED-Panel wie das bestehende WEO012864K mit einer Blende (Rahmen) auf dem Modul. Seine FPC-Pinbelegung wurde genau wie WEX012864L (30 Pins) definiert. Das WEF012864Q hat eine COG-Stuktur; es kann aber als eine Alternative zum TAB-Modul WEX012864L angesehen werden.
Das WEF012864Q ist ein OLED-Display der COG-Struktur. Es ist sehr dünn, leicht und ist sehr sparsam im Verbrauch. Das Module eignet sich für Handgeräte, Messgeräte, Heimanwendungen, POS-Systeme, Cloud / IoT-Systeme, intelligente Technologiegeräte, Energiesysteme, Kommunikationssysteme, medizinisches Instrumente usw. Es kann bei Temperaturen von -40 ℃ bis + 80 ℃ betrieben werden; die Lagertemperatur liegt zwischen -40 ° C und + 80 ° C.

| No. | Symbol | Beschreibung | |||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | NC | No connection | |||||||||||||||
| 2 | VCC | Power supply for panel driving voltage. This is also the most positive power voltage supply pin. | |||||||||||||||
| 3 | VCOMH | COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. |
|||||||||||||||
| 4 | IREF | This pin is the segment output current reference pin. IREF is supplied externally. |
|||||||||||||||
| 5~12 | D7~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. |

| 13 | E/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. |
|||||||||||||||
| 14 | R/W# | 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. When serial or I2C interface is selected, this pin must be connected to VSS. |
|||||||||||||||
| 15 | 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. |
|||||||||||||||
| 16 | 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. |
|||||||||||||||
| 17 | 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). |
|||||||||||||||
| 18 | NC | No connection | |||||||||||||||
| 19 | BS2 | MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS2 and BS1 are pin select
(1) 0 is connected to VSS (2) 1 is connected to VDD |
