Description

WEO012864AL est un module d'affichage OLED graphique de structure COG de 2,42 pouces, d'une résolution de 128x64 pixels. Ce module est intégré à l'IC SH1106 ; il peut être communiqué via l'interface I2C, le bus série SPI à 4 fils ou l'interface parallèle 6800, 8080, et son rapport de contraste élevé de 10 000:1 rend l'image de l'écran plus claire. La tension d'alimentation logique est comprise entre 1,65 V et 3,3 V (valeur typique 3V), la tension d'alimentation pour l'affichage est comprise entre 6,4 V et 13,5 V (valeur typique 13V), le devoir de pilotage est de 1/64. La série WEO012864AL propose en option des versions de carte PCB, de ZIF FPC et de Hotbar FPC.

L'affichage OLED COG est très adapté aux produits portables, aux instruments de mesure, aux compteurs intelligents, aux produits portables, aux appareils IoT, etc., grâce à ses caractéristiques de finesse, de légèreté et de faible consommation électrique. Ce module peut fonctionner à des températures de -40°C à +80°C ; ses températures de stockage vont de -40°C à +85°C.

14 NC No connection
15 /CS This pad is the chip select input. When /CS= “L”, then the chip select becomes active, and data/command I/O is enabled.
16 /RES This is a reset signal input pad. When /RES is set to “L”, the settings are initialized. The reset operation is performed by the /RES signal level.
17 A0 This is the Data/Command control pad that determines whether the data bits are data or a command.
A0 = “H”: the inputs at D0 to D7 are treated as display data.
A0 = “L”: the inputs at D0 to D7 are transferred to the command registers.
In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver.
18 /WR
(R/W)		 This is a MPU interface input pad.
When connected to an 8080 MPU, this is active LOW. This pad connects to the 8080 MPU/WR signal. The signals on the data bus are latched at the rising edge of the /WR signal.
When connected to a 6800 Series MPU: This is the read/write control signal input terminal.
When R/W= “H”: Read.
When R/W= “L”: Write.
19 E/RD This is a MPU interface input pad.
When connected to an 8080 series MPU, it is active LOW. This pad is connected to the /RD signal of the 8080 series MPU, and the data bus is in an output status when this signal is “L”.
When connected to a 6800 series MPU, this is active HIGH. This is used as an enable clock input of the 6800 series MPU.
When /RD = “H”: Enable.
When /RD = “L”: Disable.
20~27 D0~D7 This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus.
When the serial interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SI). At this time, D2 to D7 are set to high impedance.
When the I2C interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SDAI). At this time, D2 to D7 are set to high impedance.
28 IREF This is a segment current reference pad. A resistor should be connected between this pad and VSS. Set the current at 18.75uA.
29 VCOMH This is a pad for the voltage output high level for common signals.
A capacitor should be connected between this pad and VSS.
30 VPP OLED panel power supply. Generated by internal charge pump.
Connect to capacitor. It could be supplied externally.
31 ESD_GND ESD Ground pin
