설명

WEO012864AL, 이 제품은 COG OLED 디스플레이로 128 x 64도트로 구성되어 있으며 , 개별 단색으로 구성되었습니다, 대각선 길이는 2.42인치입니다. 이 모듈의 모듈 크기는 60.5 × 37.0 mm이며 활성 영역 면적은 55.01 × 27.49 mm입니다, 대비(일반값) 는 10,000:1입니다.

WEO012864AL, 이 OLED 모듈에는 SH1106 컨트롤러나 그와 동급의 IC가 기본 내장되어 있습니다. 이 제품은 6800, 8080, 4와이어 SPI 및 I2C 인터페이스. 이 2.42인치 OLED 모듈 시리즈의 작동 온도는 -40℃에서 +80℃이며, 보관 온도 범위는 -40℃에서 +85℃입니다. 논리 공급 전압의 경우 1.65V에서 3.3V, 일반값 3V, 구동 부하 1/64입니다.

유기 발광 다이오드(Organic Light-Emitting Diode, OLED)는 차세대 기술로, 더 밝고 선명한 이미지에 더욱 빠른 응답 속도를 제공합니다. 이 모듈은 초박형의 소형 경량 COG OLED 디스플레이로, 전력 소모량도 적습니다. 스마트홈 가전, 의료 기기, 휴대용 디바이스, 웨어러블 디바이스 등에 매우 적합합니다.

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.

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
