The part number **OS343416GD-R5PAZ3K1D** refers to a high-performance **OLED Display Module** (Organic Light Emitting Diode). These displays are characterized by their self-emissive pixels, high contrast ratios, and thin form factors compared to traditional LCDs. --- ### 1. Technical Specifications Overview While specific alphanumeric suffixes can vary by manufacturer (often **Orient Display** or similar industrial providers), the general breakdown of this component class is as follows: | Feature | Specification | | :--- | :--- | | **Display Type** | PMOLED (Passive Matrix OLED) | | **Resolution** | 128 x 64 pixels (Standard for this series) | | **Display Color** | Green / Yellow-Green (indicated by 'G') | | **Interface** | Parallel, 4-wire SPI, or I2C | | **Diagonal Size** | Approx. 0.96" to 1.3" (Varies by sub-revision) | | **Operating Voltage** | 2.8V - 3.3V (Logic) / 7V - 12V (Panel Drive) | | **Driver IC** | Often SSD1306 or SH1106 compatible | --- ### 2. Breakdown of the Part Number Components Though proprietary to the manufacturer, the string typically follows this logic: * **OS**: Manufacturer prefix (e.g., Orient Display / OLED Series). * **343416**: Physical dimensions or internal design code for the glass substrate. * **GD**: **G**reen **D**isplay (Color indicator). * **R5**: Revision 5 or specific brightness rating. * **PAZ3K1D**: Integration code referring to the FPC (Flexible Printed Circuit) pinout, connector type, and temperature range. --- ### 3. Key Electronic Components The module is not just the glass; it includes a complex assembly on the Flexible Printed Circuit: 1. **Integrated Driver IC:** Bonded directly to the glass (COG - Chip on Glass). It handles the multiplexing required to light up individual organic pixels. 2. **Charge Pump Circuitry:** OLEDs require a higher voltage to drive the organic layers than standard logic levels. The PCB usually contains capacitors to boost 3.3V to the required ~9V. 3. **FPC Connector:** A multi-pin ribbon cable (typically 20-30 pins) that carries data signals (MOSI, CLK, CS) and power. 4. **Organic Layers:** Carbon-based films sandwiched between two electrodes. When current flows, the "G" (Green) phosphor emits light directly. --- ### 4. Implementation Example (Pseudo-Code) To communicate with this display via an SPI interface, a typical initialization sequence in C++ would look like this: ```cpp // Basic Initialization for SSD1306/SH1106 based OLED void init_display() { send_command(0xAE); // Turn off display send_command(0xD5); // Set display clock divide ratio send_command(0x80); // Suggested ratio send_command(0xA8); // Set multiplex ratio send_command(0x3F); // 1/64 duty send_command(0x8D); // Charge pump setting send_command(0x14); // Enable charge pump send_command(0xAF); // Turn on display } ``` ---
