How to Choose an OLED Display

Table of Contents

OLED displays have emerged as a leading technology, captivating consumers with their vibrant colors, high contrast ratios, and energy efficiency. As a cutting-edge display technology, OLEDs have found their way into numerous applications, from smartphones and televisions to wearable devices and automotive displays. However, selecting the right OLED display for your specific needs can be a daunting task, considering the wide array of options available in the market.

At GoldenMorning, we understand the importance of choosing the perfect OLED display for your project. As a leading provider of OLED displays, we aim to make this decision-making process easier for you. In this comprehensive guide, we will discuss the key parameters and considerations to keep in mind when selecting an OLED display, ensuring you make an informed decision that aligns perfectly with your requirements.

Diagonal Screen Size

The first factor to consider is the diagonal screen size of the OLED display. This parameter determines how large the display will be and influences the visual experience it can provide. Assess the available space and the intended use of the display to decide on an appropriate diagonal size, such as 2.8 inches or larger, that suits your application best.


OLED displays come in two primary color options: monochrome (white) and full-color. For applications that require simple graphics and icons, a monochrome OLED display may suffice, while full-color displays are ideal for showcasing intricate images, videos, and vibrant content. Evaluate your project’s visual requirements to determine the appropriate color option.

Model Number and Resolutions

Every OLED display has a unique model number, such as GME25664-40, and is characterized by its resolution, denoted by the number of pixels horizontally and vertically. Higher resolutions, like 256×64 pixels, offer better image clarity and detail. Match the model number and resolutions with your display’s intended application to ensure optimum performance.

Outline Dimension and Active Area

The outline dimension of the OLED display refers to its overall physical size, including length, width, and thickness. In contrast, the active area represents the portion of the display that contains the pixels responsible for producing the image. Consider the available space in your project and ensure the display’s outline dimension and active area fit perfectly.

Pixel Pitch and Pixel Size

Pixel pitch indicates the distance between the centers of two adjacent pixels, both horizontally and vertically. A smaller pixel pitch results in higher pixel density and improved resolution. Pixel size, on the other hand, specifies the dimensions of an individual pixel. Choose an appropriate pixel pitch and size based on the level of detail your application requires.

Driver IC

The driver IC (Integrated Circuit) is a critical component responsible for controlling the OLED display and driving the individual pixels. Ensure that the OLED display you choose utilizes a reliable and compatible driver IC, such as SSD1322, to ensure seamless functionality and optimal performance.

Voltage and Interface

Check the operating voltage range required for the OLED display to function correctly, such as 3-5V. Additionally, consider the type of interface the display supports, whether it’s 8-bit Parallel, SPI, I²C, or others, as this will determine how you can connect the OLED to your system.

Operating and Storage Temperature

The recommended operating temperature range for the OLED display, typically between -30℃ to 70℃, ensures stable performance under normal conditions. Additionally, the storage temperature range of -40℃ to 80℃ protects the OLED display during periods of non-use and transportation.

Assemble and Pins

Understand the assembly requirements of the OLED display, such as soldering, and ensure you have the necessary expertise and equipment to handle the assembly process. Furthermore, consider the number of pins on the OLED display, as it corresponds to the interface connection points.


Choosing the right OLED display is a crucial step in ensuring the success of your project. At GoldenMorning, we believe that considering the aspects mentioned in this comprehensive guide will help you make an informed decision. From diagonal screen size and color to resolutions, outline dimension, and driver IC, each parameter plays a vital role in determining the display’s performance and suitability for your application.
