OLED 0.96" I2C IIC SPI Serial 128X64 WHITE Display LCD LED Module for Arduino What is OLED? OLED (Organic Light-Emitting Diode) is a self light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. In contrast to LCD technology, OLED does not require a backlight. OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel displays. The use of OLED technology offers the following advantages for flat-panel displays? 1. A simplified manufacturing process compared to TFT-LCD (See comparison of Picture 1 and Picture 2 below) 2. Self-emitting light, in contrast to the required backlight for TFT-LCD 3. High luminosity 4. Lightweight and thin (less than 2 mm) 5. Capable of wide viewing angles?~180?? 6. Low operating voltage and power consumption 7. Quick response (~ ? second level) 8. Wide range of operating temperatures (-40c to 85c) A Comparison of OLED and TFT-LCD Display Technologies How Does OLED Emit Light? OLED"s basic structure consists of organic materials positioned between the cathode and the anode, which is composed of electric conductive transparent Indium Tin Oxide (ITO). The organic materials compose a multi-layered thin film, which includes the Hole Transporting Layer (HTL), Emission Layer (EML) and the Electron Transporting Layer (ETL). By applying the appropriate electric voltage, holes and electrons are injected into the EML from the anode and the cathode, respectively. The holes and electrons combine inside the EML to form excitons, after which electroluminescence occurs. The transfer material, emission layer material and choice of electrode are the key factors that determine the quality of OLED components. Interface: VCC: 3.3-5V GND: Ground SCL: Serial Clock SDA: Serial Data Needn't backlight, the display unit can self-luminous High resolution: 128 * 64 Viewing angle:> 160 ° Supports many control chip: Fully compatible with Arduino, 51 Series, MSP430 Series, STM32 / 2, CSR IC, etc. Ultra-low power consumption: full screen lit 0.08W Voltage: 3V ~ 5V DC Working Temperature: -30 c ~ 70 c Module Size: 27.3MM *27.8MM I2C/IIC Interface, need 2 IO only. Driver IC: SSD1306 Note: This item come I2C/IIC interface only. Because the hardware reasons, resulting IIC/I2C bus no ACK response signal, so IIC IIC communication Whitby automated production of OLED modules instead of the standard version. But this can be solved by software...... published here for the Arduino library file, you can make this OLED module used in the Arduino system. Download File description:- IIC_without_ACK.cpp - SSD1306 drivers; IIC_without_ACK.h - SSD1306 driver file header; oledfont.c - matrix table (you need to display the contents of the matrix can be calculated by taking the modulus of software after adding this file, modulo the way " common cathode - out line - Reverse Output"; font will take up a lot of space FLASH, please comment out the unwanted font, so there will be enough space Arduino tips). Function:- Write_IIC_Byte (unsigned char IIC_Byte); / / by IIC write an 8-bit data (such as 0xff) Write_IIC_Command (unsigned char IIC_Command); / / write command to the OLED module through IIC bus Begin_IIC_Data (); / / write data through the IIC bus open ready (which would allow a group of data transmission is complete and then turn off IIC, can greatly speed) IIC_SetPos (unsigned char x, unsigned char y); / / Set the starting point coordinates (x range 0 ~ 128, y ranges from 0 to 7) Fill_Screen (unsigned char fill_Data); / / Fill_Screen (0xff) - Full screen lit; Fill_Screen (0 × 00) - Full screen off (can be used to clear the screen) Char_F6x8 (unsigned char x, unsigned char y, const char ch ); / / display the ASCII character 6 × 8 Char_F8x16 (unsigned char x, unsigned char y, const char ch );/ / display the ASCII character 8 × 16 CN_F16x16 (unsigned char x, unsigned char y, unsigned char N); / / display of 16 × 16 characters (this can be considered for the first time on the Arduino platform to achieve the display of Chinese characters) Draw_BMP (unsigned char x0, unsigned char y0, unsigned char x1, unsigned char y1, const char BMP ); / / display BMP images of 128 × 64 The other functions is functional function. Usage: Please "IIC_without_ACK" folder to x: / arduino-1.5.5 / libraries directory, restart the Arduino IDE; Demo_IIC is based on the Arduino UNO sample program...... correct wiring and run.
