Application technology丨13″ dual-screen multi-curvature integrated black car OLED display
Declaration field丨Intelligent cockpit
Technical description：
Tianma’s first dual 13-inch multi-curvature integrated black OLED display adopts a multi-curvature design, with a radius curvature ranging from R800mm to R2160mm, to meet the streamlined styling needs of the cockpit interior. The overall reflectivity of the module is 0.5%, the Delta E < 0.8, and the boundary between the two screens is not visible when the screen is off. When the screen is on, it can also present the display effect of an integrated OLED large screen. At the same time, this display adopts Tianma SLOD technology (Stacked Layer OLED Device) and TPOT (Touch Panel on Thin Film Encapsulation) technology, with high contrast, high brightness, narrow bezels, low power consumption and other display characteristics, making the screen thinner, lighter and longer life, providing a strong guarantee for driving safety.
Unique advantages:
1. Dual-screen multi-curvature design. The radius of curvature is R800mm~R2160mm, and the gradient design scheme reflects the advantages of flexible OLED displays, and also provides ideas for the streamlined integrated design of the display screen and the terminal cockpit interior.
2. Integrated black design: The use of Corning’s latest dual-screen all-in-one black cover coating technology makes the overall reflectivity of the module reach 0.5%, Delta E < 0.8, when the screen is off, it is visually displayed as an integrated large screen, and the viewing angle effect is better, which provides a reference for the overall effect of the cockpit multi-screen trend.
3. Ultra-thin design: This product has the advantage of ultra-thin OLED display, with a thickness of only 6.5mm, which is visually lighter and more beautiful for consumers, and also saves space for the cockpit.
This automotive-grade OLED display has excellent display performance and innovative design concepts, which is very suitable for high-end cockpits.
1. Extreme black, more advanced: integrated black ΔE 0.78, with integrated large screen display effect, to achieve true “stealth”
2. Multi-curvature, more compliant: the radius of the curved surface changes from R800mm to R2160mm, which can better match the streamlined shape of the cockpit interior
3. High brightness, more readable: 10% APL (Average Picture Level) > 1500nit, which can enhance the readability of the pure black interface OLED screen, and the screen text brightness reaches 1100nit, ensuring the readability of excellent brightness while ensuring the integrated black effect
4. Wide color gamut, more colorful, > 103% (NTSC), which can enhance the rich color experience
5. High contrast, clearer: richer details and clearer layers
6. Extremely thin and lighter: 6.5mm, which makes the cockpit space more concise and beautiful
Application Scenarios:
Instrument + central control
Future prospects:
Tianma This product solves a variety of terminal and user concerns, and can directly benefit consumers.
Solves the problem of color difference between the screen and the CG Lens: this display has a performance of Delta E<0.8 and a reflectivity of 0.5%, which makes the CG Lens and the screen fully integrated, providing a reference for the overall effect of the cockpit multi-screen trend.
Solves the cost problem caused by large-screen lamination: this display realizes the visual effect of dual-screen integration, and its production cost and lamination process yield are more cost-effective than large-screen lamination.
Solves the problem of screen readability in the integrated black and bright state: (1) Tianma’s original SLOD technology superimposes the local white highlighting function, and the local white brightness of the screen > 1500nit, making the screen have excellent readability. (2) Extremely high reflected light contrast: The reflectivity of this display is extremely low, and it still has excellent readability under strong external light, which is more conducive to the user’s driving needs and safety.
Environmental Protection Concept:
1. High recovery: Cold-bending design provides excellent optical properties, enables more economical industrial mass production, and contributes to global warming: Coldbay glass contains 24% recycled material, and Coldbay technology can reduce global warming potential by up to 25% in life cycle evaluation
2. Low cost: This display realizes the visual effect of dual-screen integration, and its production cost and lamination process yield are more cost-effective than large-screen lamination.
3. Low-carbon environmental protection: Tianma SLOD display technology is adopted, and its low power consumption and long life characteristics help low-carbon environmental protection
