1.3 Inch OLED Display Dimensions: A Complete Guide for Engineers & Buyers

 

If you’re designing wearable devices, portable instruments, or compact electronics, understanding 1.3 inch OLED display dimensions is critical for seamless integration. This guide breaks down key measurements, industry standards, and how OPL’s offerings align with practical application needs.

 

Core Dimensions of 1.3 Inch OLED Displays

The term "1.3 inch" refers to the diagonal length of the display panel, but functional integration requires clarity on two key metrics: active area (the visible display region) and module dimensions (the full physical size including drivers and connectors).
 

1. Active Area Specifications

The active area varies slightly by resolution and aspect ratio, with two common configurations dominating the market:

  • 128×64 Resolution (Standard Aspect Ratio): Most monochrome 1.3 inch OLEDs feature an active area of 29.42mm × 14.70mm . This matches the pixel arrangement of drivers like SH1106 and SSD1306, ensuring compatibility with Arduino and Raspberry Pi systems .
  • 64×128 Resolution (Vertical Orientation): Ideal for wearable devices, this variant has an active area of 14.70mm × 29.42mm , fitting seamlessly into smartwatch casings.
  • 360×360 Resolution (Square Color Displays): Color AMOLED models offer a square active area of 32.94mm × 32.94mm, supporting vivid 16.7M color output for premium wearables .

2. Module Dimensions

Module size includes the PCB, driver IC, and connectors—critical for enclosure design:

  • Monochrome Modules: Typical dimensions range from 30.0mm × 39.5mm (for vertical 64×128 models) to 40.5mm × 37.5mm (for angled-connector variants) . Thickness averages 3.7mm–6.2mm .
  • Color AMOLED Modules: Advanced models like OPL’s 360×360 variant achieve ultra-slim profiles (35.34mm × 36.84mm × 0.69mm) via COG (Chip-on-Glass) packaging .
  • Compact I2C/SPI Modules: For space-constrained projects, modules like OPL’s 128×64 model measure just 35.4mm × 33.5mm × 4.3mm .

Key Factors Influencing Dimensions

Resolution & Pixel Pitch

Pixel density directly impacts display clarity without altering diagonal size. 1.3 inch OLEDs typically have:

  • 0.21mm–0.23mm pixel pitch for 128×64 resolutions
  • 0.15mm–0.17mm pixel pitch for 360×360 high-definition models

Interface & Connector Type

  • I2C/SPI Interfaces: Modules with these compact interfaces (common in OPL’s lineup) maintain smaller footprints than parallel-interface alternatives .
  • Connector Orientation: Angled headers add width but reduce height, while straight connectors optimize vertical space —OPL offers both options for flexible integration.

Application-Specific Dimension Considerations

Wearable Devices (Smartwatches/Bracelets)

 

Prioritize slim modules (≤5mm thickness) and vertical active areas. OPL’s 64×128 model (14.70mm × 29.42mm active area) fits standard 40mm watch cases while supporting 160°+ viewing angles .

 

Industrial Instruments

Require rugged packaging and wide temperature tolerance (-30°C to 70°C). OPL’s 128×64 module (35.5mm × 33.5mm) includes mounting holes (2.5mm diameter) for secure panel installation .[

 

DIY Electronics & Prototyping

Balance size and compatibility. OPL’s 1.3 inch OLED works with ESP32/STM32 boards, featuring pre-calibrated dimensions for 3D-printed enclosures .

 

OPL’s 1.3 Inch OLED Display Offerings

OPL manufactures industry-compliant 1.3 inch OLED modules tailored to diverse applications:

  • Monochrome Series (OPL-M130): 128×64 resolution, 29.42×14.70mm active area, 35.4×33.5×4.3mm module size, SH1106 driver, and I2C/SPI compatibility .
  • Color AMOLED Series (OPL-C130): 360×360 resolution, 32.94×32.94mm active area, 0.69mm thickness, and QSPI interface for fast data transfer .
  • Vertical Wearable Series (OPL-V130): 64×128 resolution, optimized for smartwatches with 14.70×29.42mm active area .

All OPL modules meet RoHS standards and include technical datasheets with detailed dimension drawings.

How to Choose the Right Dimensions

 

  1. Measure Enclosure Space: Confirm maximum allowable length/width/thickness for the module.
  2. Check Resolution Needs: 128×64 suffices for text/graphics; 360×360 is for color-rich UIs.
  3. Verify Interface Compatibility: Ensure connector orientation fits your PCB layout.
