0.39-inch 1024 by 768 XGA Micro OLED display module

Compact XGA Micro OLED Image Source

The 0.39″ Micro OLED display is a compact, full-color OLED-on-Silicon module within DisplayMan’s broader Micro OLED displays portfolio. Its native 1024 × 768 XGA resolution is presented across an 8.1325 × 6.1779 mm active area.

The self-emissive structure provides true black, strong contrast and fast response without a separate LCD backlight. The XGA format is especially practical for electronic viewfinders, microscope eyepieces, thermal viewers and compact professional optical instruments.

Reference Platform

Why Choose a 0.39″ Micro OLED?

Compact

Compact XGA Format

The 8.1325 × 6.1779 mm viewing area combines compact dimensions with a practical 4:3 XGA image format.

Image Quality

1024 × 768 Detail

XGA resolution supports detailed menus, image composition, focusing assistance and professional optical overlays.

Motion

25–120 Hz Operation

A high-frame-rate direction supports smoother motion when the host, driver and complete pipeline are configured accordingly.

Contrast

Self-Emissive Pixels

True black and high contrast help small graphics and image edges remain visible after optical magnification.

Interface

Flexible Signal Options

RGB / YCbCr video inputs and I²C control provide practical integration paths for compact embedded systems.

Environment

Wide Temperature Range

The reference operating range supports evaluation for industrial and professional optical products.

Typical Applications

Electronic Viewfinders

XGA detail, compact size and image controls for cameras, inspection equipment and professional imaging systems.

Microscope Eyepieces

A compact electronic image source for microscopes, digital eyepieces and laboratory optical instruments.

Thermal Imaging Viewers

Strong contrast and a practical XGA format for portable thermal and observation devices.

Compact Head-Mounted Displays

Suitable for monocular near-eye viewers where XGA resolution and compact size meet the optical requirement.

Industrial Inspection

Useful for measurement, maintenance and embedded viewing equipment that requires a miniature electronic eyepiece.

How the 0.39″ Micro OLED Fits into a System

The panel is one part of the complete image chain. System performance depends on every element around it.

Electronic Integration

  • Match RGB or YCbCr timing to the selected module.
  • Provide the required 1.8 V and 5.0 V power rails and correct power sequence.
  • Control display settings through the correct I²C commands.
  • Review host input conversion, refresh rate and latency as one pipeline.

Optical Integration

  • Match the active area to the eyepiece focal length and magnification.
  • Define field of view, eye relief, exit pupil and image orientation.
  • Evaluate MTF, distortion, color and brightness after optical loss.
  • Control alignment, focus and mechanical tolerances during assembly.

When Should You Select the 0.39″ Platform?

Good Fit

Select 0.39″ When

  • Compact package size has high priority.
  • XGA resolution is adequate for the application.
  • The design can provide RGB or YCbCr video input.
  • EVF, microscope, thermal imaging or another optical viewer is the target device.
  • Low power consumption and wide-temperature operation are important.
Compare First

Review a Larger Platform When

  • Full HD or higher resolution is required.
  • The optical design needs a larger active area.
  • Fine text or detailed imagery remains insufficient after magnification.
  • The target field of view and optical architecture favor another display size.
  • Your driver platform cannot support the required RGB or YCbCr timing.
Do Not Select by Size Alone

Display size, resolution, brightness, field of view, focal length, interface and mechanical envelope must be reviewed together.

0.39″ Micro OLED Display FAQ

What is the resolution of the 0.39″ Micro OLED?

TAS039XGH01 provides a native 1024 × 768 XGA resolution with an RGB vertical-stripe pixel arrangement.

What is the brightness of TAS039XGH01?

The data-sheet reference is 200 cd/m² typical, with a 40–400 cd/m² luminance-adjustment range. Confirm the production version and operating settings before design-in.

Which video interfaces does the display support?

The platform supports 24-bit RGB and 8/16/24-bit YCbCr digital video input, with I²C used for programming and control.

Can it connect directly to HDMI or USB Type-C?

Normally no. HDMI or Type-C sources require matching conversion and driver electronics that provide the correct video timing, control and power sequence.

Is the 0.39″ Micro OLED suitable for EVF?

Yes. Its compact XGA format, contrast and image-control functions make it a practical direction for electronic viewfinders, subject to complete optical evaluation.

Does the panel include an eyepiece?

No. The Micro OLED is the image source. Eyepiece optics, focus mechanics and housing are separate unless an integrated EVF optical module is specified.

Can DisplayMan provide a driver board or optical module?

DisplayMan can review compatible driver electronics, EVF optical modules and near-eye integration requirements according to the host input, field of view and mechanical space.

What information is needed for a quotation?

Please provide the application, quantity, host input, brightness requirement, optical specifications, mechanical limits and project schedule.
