CUSTOM OLED DISPLAY Details

What Is an AMOLED OLED Display?

An AMOLED (Active Matrix Organic Light Emitting Diode) OLED Display differs fundamentally from traditional LCDs because it does not require a backlight. Each pixel emits its own light. This self-emissive technology allows for "true blacks" (by simply turning off pixels), an infinite contrast ratio, and significantly lower power consumption when displaying darker content. The result is a thinner, lighter, and more vibrant screen that elevates the user experience.

Unmatched Visual Brilliance

Infinite Contrast and 100% NTSC Color Gamut

With a contrast ratio of 100,000:1 and a color gamut covering 97-100% of NTSC, this OLED Display produces deep, inky blacks and vivid, lifelike colors. The 568x1210 resolution ensures sharp text and detailed graphics, making it superior for interfaces requiring high-definition visual fidelity.

Integrated Interaction

On-Cell Capacitive Touch Technology

Unlike standard modules that require a separate touch layer, this unit features On-Cell touch technology using the CST3530 IC. This integration reduces the module's total thickness and improves optical clarity by removing air gaps, ensuring precise and responsive touch performance.

Ultra-Thin Mechanical Profile

0.75mm Thickness for Sleek Designs

One of the primary advantages of this OLED Display is its physical profile. Without the need for a bulky backlight unit, the module achieves an incredibly slim depth of just 0.75mm. This allows product designers to create thinner, lighter handheld devices without compromising on battery space.

High-Speed Connectivity

Efficient MIPI 2-Lane Interface

Powered by the SD5207 driver IC, the display utilizes a MIPI DSI (Mobile Industry Processor Interface) 2-lane connection. This high-speed interface supports the 60Hz frame rate necessary for smooth animations and video playback while minimizing electromagnetic interference (EMI).

Wide Viewing Angles

Consistent Visibility from Any Direction

The self-emissive nature of the OLED panel provides ultra-wide viewing angles. With visibility of 80/80/80/80 degrees (Left/Right/Top/Bottom), the screen remains clear and color-accurate even when viewed from extreme angles, which is critical for wall-mounted or handheld applications.

Why Choose ReissOpto for Your OLED Projects?

Advanced LTPS Technology
We utilize LTPS (Low-Temperature Poly-Silicon) backplanes for our OLED Display modules. This technology allows for higher electron mobility, resulting in higher resolution density and lower power consumption compared to standard amorphous silicon panels.

Strict Quality Control
Our manufacturing process adheres to rigorous standards. Every AMOLED module undergoes high/low-temperature storage testing (-40℃ to +80℃) and ESD testing to ensure reliability in harsh environments. We guarantee zero "dead pixels" upon delivery.

Customization Services
ReissOpto offers full customization for the FPC (Flexible Printed Circuit) shape, pin definition, and cover glass design. We can tailor the mechanical housing to fit your specific device enclosure perfectly.

Application Scenarios

Smart Home Control Panels
The vertical aspect ratio and high contrast make this OLED Display ideal for modern wall-mounted thermostats, smart knobs, and lighting controllers.

Handheld Medical Instruments
High clarity and true black levels allow for precise reading of medical data and waveforms in portable diagnostic equipment.

Industrial Handhelds
The wide operating temperature range (-20℃ to +70℃) ensures reliable performance for industrial scanners and remote controls used in varying environments.

Consumer Electronics
Perfect for high-end remote controls, translator devices, and dictation recorders where a premium visual interface is a key selling point.

Frequently Asked Questions (FAQ)

Q1: Does this OLED Display require a backlight driver?
A1: No. Unlike TFT LCDs, an OLED Display is self-emissive and does not use a backlight. It requires power for the ELVDD/ELVSS (OLED driving voltages) and logic power, which simplifies the power circuit design in some aspects.

Q2: What is the lifespan of this AMOLED module?
A2: The LT95 lifespan (time to 95% brightness) is approximately 250 hours under continuous full white pattern at 25°C. However, in normal use cases (dynamic content, dark themes), the operational lifespan is significantly longer, suitable for consumer and industrial lifecycles.

Q3: Can I use this display in outdoor environments?
A3: Yes. With a brightness of up to 600 nits and the inherent high contrast of OLED technology, this display offers excellent readability in outdoor or high-ambient-light conditions.

Q4: Is the touch panel included?
A4: Yes, this model comes with an integrated On-Cell Capacitive Touch Panel (CTP) driven by the CST3530 IC, supporting multi-touch functionality.

Q5: How do I prevent screen burn-in?
A5: We recommend using "pixel shift" software techniques and avoiding displaying static high-brightness images for extended periods. Our technical support team can provide algorithms to maximize the longevity of the OLED Display.
