How to Choose a Connector for an OLED Display

We know that millions of OLED TVs are shipped every year. But besides these big screens, OLEDs are also used in thousands of other ways, like handheld devices and appliances that we use every day.

A fascinating thing about OLEDs is that they’re a solid-state semiconductor device that can be just 100 nanometers thick. That’s about 200 times thinner than human hair, making OLED displays a top choice for applications with strict size requirements.

Whether you’re looking to add a high-quality screen to a tractor dashboard, an industrial machine, or an infusion pump, OLED displays can offer the flexibility and performance you need.

Once you have chosen an OLED to use in your product, you will need to consider other components that will be required, one of which is the connector.

This component is more important than you might think. It ensures your display connects seamlessly with the rest of your assembly and prevents costly issues like signal interference, wasteful power usage, or other mechanical hiccups.

To help you choose, here’s our guide to what to consider when choosing a connector for OLED displays.

The Basics of OLED Displays

OLED, or Organic Light Emitting Diode, uses organic compounds that emit light when an electric current passes through them. Compared to LCDs made of crystals, OLEDs can be flattened to become thinner and more flexible.

One of the most exciting uses of OLED technology is its potential to be made into super small screens. This is possible because OLEDs are ‘self-emissive,’ which basically means that each pixel produces its own light. No bulky backlights needed.

OLED displays can deliver vibrant colors or can be selected in monochrome versions.  Regardless of which is selected, they both come in an ultra-thin package. Imagine the possibilities in small devices like handheld products. Especially when displaying dark interfaces, OLEDs are great for portable devices with their low power consumption.

As this technology continues to develop, we can expect to see even more innovative uses for these compact and efficient screens.

Types of Connectors to Consider for OLED Displays

When working with OLED displays, there are different types of connectors to choose from. Each type has its own uses and benefits. Let’s break it down:

Flexible Printed Circuit (FPC) Connectors

FPC connectors are perfect for tight spaces or designs that need flexibility. These consist of a thin plastic substrate with printed conductive traces. Many OLEDs offer a solderable FPC type of connector which is ideal for applications with extreme space constraints.

Flat Flexible Cable (FFC) Connectors

As popular as FPC connectors, the FFC connectors feature broader, ribbon-like cables. They connect circuit boards without bulky connectors, so they can be inserted and removed much more easily. FFC connectors are great for devices like printers, laptops, and cameras where a low-profile connection is needed.

Pin Headers

Pin headers are easy-to-use connectors with rows of metal pins that can be soldered to a printed circuit board (PCB) or used with matching sockets. 

They are commonly used in prototyping, testing, and industrial equipment where a strong, reliable connection is needed. Pin headers are also versatile and come in various sizes and configurations. 

Board-to-Board Connectors

As the name implies, two circuit boards can be directly connected with board-to-board connectors. The stacking and edge configurations provide a stable and compact connection. These connectors are mainly used in compact devices that need to save space.

Wire-to-Board Connectors

Wire-to-board connectors are designed to connect wires directly to a PCB. They come in various types, such as crimped, soldered, and IDC (Insulation Displacement Connector). These connectors are ideal for applications like automotive, industrial, and home appliances where a secure connection is needed.

Compression Connectors

Compression connectors use mechanical pressure to make a connection between contacts. They are useful in situations where soldering isn’t feasible or when the connection needs to be easily changed.

Key Considerations for Choosing OLED Display Connectors

Knowing the type of connector is just the start. You’ll need to consider other factors so you can choose the right one for your device and maximize your output. Here are the key considerations you need to know:

• Connector Type: The type will depend on your specific application and design.
• Pin Count and Layout: Make sure the connector matches the pin configuration of your display and other components to ensure proper connectivity and signal transmission.
• Compatibility: Compatibility with the signal types (analog, digital) is critical for preventing data loss or interference.
• Form Factor: The connector’s physical size and shape must fit your device’s design, so keep space constraints in mind.
• Mechanical Durability: Look for connectors that can withstand harsh environments, such as heat or cold, physical stress, vibration, and other mechanical factors.
• Electrical Performance: Check the connector’s electrical specifications, such as the resistance, current rating, and voltage rating, for the best display performance and reliability.
• Ease of Assembly and Maintenance: Consider how easy it is to install and remove the connector to save time and reduce the risk of damage during installation.
• Cost and Availability: Balance the cost of the connectors with your budget and availability to avoid delays.
• Manufacturer and Quality Assurance: Partner with a manufacturer that meets quality testing standards. Reliable manufacturers give you peace of mind with quality assurance and support, making sure your connectors are always right.

By considering these factors, you can make a well-rounded assessment when selecting the best connector for your OLED display.
