1.3 Inch OLED Display Dimensions: Complete Guide & OPL’s Specs

 

When designing wearables, medical devices, or compact electronics, 1.3 inch OLED display dimensions are critical for ensuring a perfect fit—too large and it won’t fit the enclosure; too small and it sacrifices readability. This guide breaks down the exact dimensions of 1.3 inch OLED displays (diagonal, active area, module size, and thickness), explains key terminology to avoid confusion, and details OPL’s industry-compliant 1.3 inch OLED solutions. Every specification aligns with global display standards, so you can use this information directly for prototyping, 采购 (procurement), or product development.

 

1. Core Dimension Basics: 1.3 Inch OLED Diagonal Conversion

 

First, it’s essential to clarify: all display sizes (including 1.3 inch OLED) are measured by the diagonal length of the active display area (excluding bezels and PCB). The conversion between inches and millimeters (mm) is fixed and industry-standard:

1 inch = 25.4 mm

For a 1.3 inch OLED display:

1.3 inches × 25.4 mm/inch = 33.02 mm (diagonal)

This 33.02 mm diagonal is the foundation for all 1.3 inch OLED dimensions—every other measurement (width, height, thickness) depends on the display’s aspect ratio and design.

 

2. Key Dimension Terms to Avoid Confusion

 

When reviewing 1.3 inch OLED specifications, two terms are often mixed up. Understanding them ensures you select the right display for your device:

  • Active Area (A.A.): The actual usable display area (where pixels light up). Critical for determining how much content fits on the screen.
  • Module Size: The total size of the entire display module (including PCB, bezels, and connectors). Critical for fitting the display into your device’s enclosure.

Example: A 1.3 inch OLED might have an active area of 29.42×14.7 mm, but its module size (including PCB) could be 34.5×23.0×1.4 mm .

 

3. 1.3 Inch OLED Display Dimensions by Aspect Ratio

 

Aspect ratio (width:height) is the biggest factor affecting 1.3 inch OLED dimensions. Below are the most common ratios for 1.3 inch OLEDs, with real-world specs from industry standards and OPL’s product lineup:

Aspect Ratio Resolution Active Area (W×H, mm) Module Size (W×H×D, mm) Thickness (mm) Typical Use Case
2:1 (Wide) 128×64 (Monochrome) 29.42×14.7 34.5×23.0×1.4 1.4 Industrial controllers, small sensors
1:1 (Square) 360×360 (Color AMOLED) 32.94×32.94 35.0×35.0×1.2 1.2 Smart watches, fitness trackers
4:3 240×180 (Color) 26.4×19.8 30.0×25.0×1.3 1.3 Medical wearables, portable meters
Notes:
  • All diagonal measurements are 33.02 mm (1.3 inches), per industry standard.
  • Thickness ranges from 1.0–1.4 mm (OLEDs are thinner than TFT-LCDs, as they don’t require a backlight) .
  • Resolution correlates with pixel density (PPI): 360×360 resolution on a 1:1 1.3 inch OLED delivers ~280 PPI (sharp enough for wearables).

4. OPL 1.3 Inch OLED Display: Exact Dimensions & Specs

 

OPL’s 1.3 inch OLED displays are engineered for reliability and easy integration, with dimensions tailored to common device designs. Our product lineup includes three core models, all tested to meet RoHS and CE standards:

    • Active Area: 29.42×14.7 mm
    • Module Size: 34.5×23.0×1.4 mm
    • Diagonal: 33.02 mm (1.3 inches)
  • Key Specs: 128×64 resolution, SH1107 driver IC, SPI/I2C interface, 110 cd/m² brightness
  • Advantage: Ultra-low power consumption (<5 mW standby) and wide operating temperature (-20°C to 70°C)

4.2 OPL-OLED130-C (Color AMOLED, 1:1 Aspect Ratio)

4.3 OPL-OLED130-Custom (Custom Dimensions)

  • Options: Adjust aspect ratio (e.g., 3:2), reduce module size (down to 30×22×1.0 mm), or add touch functionality
  • Process: OPL provides 3D dimension drawings and sample units within 3 working days of customization requests
  • Use Case: Niche devices (e.g., medical patches, miniaturized controllers) requiring non-standard fit

5. Why Dimension Accuracy Matters for 1.3 Inch OLED Displays

Incorrect dimensioning leads to costly redesigns—here’s what to prioritize:

  1. Active Area vs. Module Size: Ensure your device’s bezel and enclosure fit the module size (not just the active area) to avoid gaps or overlaps.
  2. Thickness Constraints: Wearables (e.g., smart watches) typically require <1.5 mm thickness—OPL’s 1.2 mm thin models fit slim designs .
  3. Connector Placement: OPL’s modules place connectors on the edge (not the front/back) to save space—critical for compact devices.
