Small oled display module usually refers to the OLED display with a size smaller than 5.5 inches. Because of limitation of technology and cost, OLED displays are mainly in small-sizes OLED displays. Small OLED displays are widely used in wearable device, smart phone, industrial display, smart home display, outdoor displays. The interfaces of small OLED displays are simple and easy to use, they are easily to be connected to Arduino, Raspberry PI system or other MCU with single chip system.

AmOLED (Active Matrix Organic Light Emitting Diode) and PMOLED (Passive Matrix Organic Light Emitting Diod E) are the two main small OLED display technologies, which have obvious differences in structure, performance, cost and application fields.
PMOLED is using passive matrix technology, each pixel is cross controlled through columns selection and rows scan, only the points both selected by column and row, the crossing point would be displayed on. PMOLED is suitable for low-resolution and small-size displays.
AMOLED driving is more likely TFT driving method, there are TFT (thin-film transistor) cell to control each pixel display on and off, which is suitable for large-size and high-resolution small OLED display.
Comparisons of AMOLED vs. PMOLED
AMOLED vs. PMOLED: Resolution and size:
AMOLED supports higher resolution and larger screen size, which is suitable for high-end smartphones and large sizes of TV screen.
PMOLED is limited by the complexity of driver lines, and the resolution and screen size are smaller. which is only used in small sizes OLED screen.
AMOLED vs PMOLED: power efficiency and image quality:
AMOLED usually has lower power consumption and better image quality, it provide higher contrast and brighter colours.
PMOLED has higher power consumption than AMOLED, and relatively lower contrast than AMOLED.
AMOLED vs PMOLED: Cost and application:
Cost: The manufacturing cost of PMOLED is low, which is suitable for cost-sensitive markets; the manufacturing cost of AMOLED is high, but it provides better display effects.
Application field: PMOLED is often used in small devices such as smart watches and portable music players; AMOLED is widely used in high-end smartphones, TVs and large displays.
Conclusion of AMOLED vs PMOLED:
AMOLED and PMOLED have their own advantages and limitations. Which technology to choose depends on the specific application needs and budget.
Although AMOLED is expensive, it provides better display quality and greater flexibility, which is suitable for users who pursue high-quality display.
PMOLED is more suitable for small OLED displays, which is cost-sensitive applications that do not require large screens.
Why most of OLED displays are small OLED display?
The popularity of OLED screens are mainly in small-sized screens, it is due to technology and cost limitations.
1. Technical limitations and costs:
When OLED screens are applied to small sized devices, the technology is relatively mature. The production of large OLED screens faces more technical challenges and higher costs, such as short life and uneven brightness. These technical limitations make the production of large-size OLED screens more difficult and expensive.
The manufacture procedure of OLED screen has high challenge to make big sizes OLED, because the luminescent powder (red, green, blue) inside OLED screen, they are evaporated to OLED glass via the metal mask in horizontal. In manufacturing big size OLED screen, the metal mask are big and heavy, therefore, the big metal mask is hard to remain as horizonal as small sizes, the slightly curve of matal mask, it lead to color mixing and high challenge in making big size and high resolution OLED screen. OLED screens in small-size applications, due to the small screen area, even if the panel material unit price is higher, the overall cost is spread out. This is particularly evident in consumer electronics such as mobile phones, which have a small screen size, but the cost of OLED has fallen with technological advances and optimization of the supply chain.
2. Display effect and energy efficiency limitations:
Due to its self-luminous characteristics, OLED screen can achieve higher contrast and wider viewing angle. However, on large OLED screens, these advantages may be affected, such as uneven brightness and lifetime problems. In addition, the energy efficiency of large-size OLED screens is not always superior to other display technologies, especially in terms of high refresh rate display and low energy consumption.
3. Market and application considerations:
Market demand: Small OLED display devices, such as smartphones and tablets, can make full use of the advantages of OLED, such as thinness, lightness, bendability and excellent colour performance. On laptops or other large devices, users may value the durability and practicality of the screen more, which may affect the popularity of OLED screens in these fields. Small-size OLED screens show unique advantages in smart kitchen appliances, smart home control systems, personal care appliances, environmental appliances and other fields because of their thin, self-lighting, high contrast and other characteristics. These applications are more inclined to use small OLED display because they can provide a more intuitive interface and a better user experience. Application scenarios: In small-size applications, such as VR/AR glasses, medical devices, mobile power supplies, etc., the high resolution and fast response time of OLED screens can provide a smooth user experience, suitable for near-eye displays and portable device needs.
Therefore, although OLED screen technology continues to evolve, it still faces cost and technical challenges in large-size applications, and small OLED displays are become more common in the market.
Small OLED display module manufacturers in China:
China OLED panel manufacturers have BOE, Tianma, Visionox, EDO, they are tier 1 OLED display
manufacturers in China, they have the newest generation production lines for small OLED display panels, making AM-OLED panels and flexible OLED displays, such as for
smartphone screens. Besides Samsung and LG from Korea, China OLED manufacturers
are the major manufactures for small OLED display market.
For small-sizes monochrome OLED panel manufacturers,
there are Visionox, Truly, Wisechips, and RIT, Winstars in Great China area, monochrome OLED panel sources are mainly comes from these OLED panel manufacturers.
Besides bigger OLED panel manufacturers, there are more OLED display modulemanufacturers in China. The production processes of small OLED display module are most likely COG LCD module production, only without backlight assembly. Small OLED display module has intergrated OLED panel, IC driver chip on glass, flex cable, sometimes with PCB adapter. The interfaces of small OLED display modules are available in IIC, SPI, MCU, MIPI interface, that they are easily to be used in common master board, such as Raspberry PI, Arduino, STM32, ESP8266.
