Descrição

WEO012864AL, Este é um display COG OLED fabricado com 128x64 pontos e tamanho diagonal de 2,42 polegadas. Este módulo tem dimensão de módulo de 60,5 × 37,0 mm e área ativa de 55,01 × 27,49 mm.

Este módulo de display OLED de 2,42 polegadas monocromático com matriz passiva 128x64 apresenta um ângulo de visualização muito amplo de até 160°. Este display OLED está integrado com o IC SH1106 que tem diferentes interfaces opcionais; suporta interface paralela de 6800, 8080, I2C, e SPI de 4 fios.

WEO012864AL, Esta série de módulos pode operar a temperaturas de -40℃ a +80℃; suas temperaturas de armazenamento variam de -40℃ a +85℃. A tensão de alimentação para lógica é de 1,65V a 3,3V, valor típico de 3 V, 1/64 para o acionamento, relação de contraste (valor típico) de 10,000:1.

O Diodo Emissor de Luz Orgânica (OLED da sigla em inglês) é uma tecnologia da nova geração, com imagens mais brilhantes e claras e com uma velocidade de resposta mais ágil. Este módulo é um display COG OLED de tamanho pequeno, ultra-fino, leve e com baixo consumo de energia. Ele é muito adequado para aplicações domésticas inteligentes, dispositivos médicos, dispositivos portáteis e dispositivos vestíveis.

Função do pino de interface

No. Símbolo Função
1 ESD_GND ESD Ground pin
2 VSS Ground.
3-10 NC No connection
11 VDD1 Power supply input
12 IM1 These are the MPU interface mode select pads.
  8080 I2C 6800 4-wire SPI
IM1 1 1 0 0
IM2 1 0 1 0
Note
(1) 0 is connected to VSS
(2) 1 is connected to VDD1
13 IM2
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
