How to make OLED transparent screen? Analysis of the whole process technology of Yetronic factory

In the field of digital display, OLED transparent screen improves the visual experience with revolutionary technology. As a manufacturer with 15 years of experience in global digital signage, Yetronic has provided transparent display solutions to more than 40 countries around the world. This article will reveal the whole process of manufacturing OLED transparent screen and analyze the technological innovation and industry application trends.

The core technical principle of OLED transparent screen

The core of OLED transparent screen lies in the precise combination of organic light-emitting layer and transparent electrode. Its self-luminous characteristics do not require a backlight module, and the double-sided display effect is achieved through an ultra-thin structure. The Yetronic R&D team has increased the screen transmittance to 45% by optimizing the material ratio, while maintaining the picture quality of 800nits brightness.

Compared with traditional LCD, the pixel-level light control technology of OLED transparent screen can achieve a contrast ratio of 1,000,000:1, which is still clearly visible in strong light environment. Yetronic laboratory test data shows that its 120Hz refresh rate can smoothly present dynamic pictures, and the 178° full viewing angle design meets the viewing needs of multiple scenes.

The entire manufacturing process of the Yetronic factory

1. Substrate material selection

Tempered glass substrate with a transmittance of over 90% is selected, and a nano-level ITO conductive layer is plated on the surface. The resistance value is controlled to ≤10Ω/sq through the magnetron sputtering process to ensure uniform current distribution. After 12 cleaning processes, the substrate enters the vacuum dust-free production line.

2. Precision graphic process

The patented laser etching technology is used to deposit red, green and blue organic light-emitting materials layer by layer in a vacuum environment. The error is controlled within ±1μm, and each 55-inch screen needs to complete more than 8 million precise positioning. Multi-layer composite film is used in the packaging stage, and the water and oxygen permeability is blocked by 99.99%.

3. Drive system integration

Equipped with Yetronic’s self-developed driver chip, it supports 50-800nits intelligent dimming. The system can control 256 screens simultaneously, with a response speed of ≤5ms. Optional infrared/capacitive touch modules are available, compatible with Android/Windows systems.

4. Strict quality inspection

Each screen must pass 3 tests: optical tester verifies color gamut coverage of 95% NTSC; 1000-hour aging test ensures life of more than 50,000 hours; -30℃ to 70℃ extreme environment simulation test stability.

Innovative application scenarios

Retail display: Yetronic customizes window solutions for flagship stores, with transparent screens and physical products superimposed on each other, increasing store conversion rates by 37%. Dynamic price tags reduce labor replacement costs and support remote real-time updates.

Museum tour: The museum uses a 55-inch transparent screen to create an interactive display cabinet for cultural relics. Visitors can view 3D cultural relic profiles through gestures, and the average daily interaction time increases by 2.3 times.

Five advantages of choosing Yetronic

Customized production: Supports special size development of 28″-88″, providing round/curved/special-shaped screen solutions. The curved curtain wall screen was customized for the project, with a bending radius of up to 1500mm.

Global certification system: Passed 28 international certifications such as CE/FCC/ROHS, and complies with ISO9001/14001 dual standards. The product has obtained UL fireproof certification and is suitable for safety-sensitive scenes such as commercial complexes.

Patent technology reserves: It has 17 transparent display-related patents, among which the microstructure light guide layer design increases the transmittance by 15% while reducing power consumption by 20%.

Future development trends of the industry

The market size of OLED transparent screens is expected to reach US$2.7 billion in 2025. Yetronic R&D Center has proposed three major technical directions: using new transparent electrode materials to make the transmittance exceed 70%; developing a rollable screen to reduce transportation costs by 40%; optimizing the drive circuit design to reduce power consumption by 30%.

The YTP-2025 project underway has achieved an ultra-thin module of 0.8mm, and the 85% NTSC color gamut coverage can accurately restore the details of artworks. The touch response speed reaches 5ms, meeting the needs of high-precision scenes such as medical imaging.

Yetronic’s manufacturing strength

The 15,000㎡ industrial park is equipped with a dust-free workshop, with a monthly production capacity of 5,000+ standard screens. 23 imported testing equipment ensures a yield rate of >98.7%, 15% of annual revenue is invested in R&D, and the technology iteration cycle is shortened to 8 months.
