In the visual performance of LED displays, the consistency of the ink color of the COB module is one of the key factors that determines the overall look and display effect of the screen.
What is ink color?
Ink color refers to the uniformity of black (or dark color) on the surface of an LED display screen when it is not lit, which can directly affect the overall visual experience of the large screen.
1. Why is ink color consistency important?
A screen with a consistent ink color presents a seamless black visual effect when the screen is off. On the other hand, a screen with a poor ink color will show color differences between modules, creating a noticeable "mosaic" effect, which affects the sense of unity and sophistication of the display.
In LED direct-view display products, the impact of uneven ink color is far greater than imagined:
Affects the overall seamlessness of the splicing
Screens with significant color differences will show obvious module boundaries when the screen is black, which will also negatively affect the contrast and make the screen surface look like a mosaic wall, which is unsightly and greatly reduces the overall display effect.
Affects screen color reproduction
Even if the LED chips themselves emit the same color, if the reflectivity of the screen surface is different, it may still cause deviations in brightness and color after being lit, resulting in uneven color distribution in the displayed image.
Therefore, improving the consistency of ink color can not only optimize the aesthetics when the screen is off, but also ensure the uniformity of color after the screen is turned on, making the whole picture more harmonious and natural.
2. How to achieve a visual experience with consistent ink color and a seamless overall effect?
To achieve a high standard of ink color consistency in COB modules, strict control is required in multiple aspects, including material selection, manufacturing processes, and assembly precision, to ensure that each module reaches the same visual level. This relies on meticulous management across the entire supply chain, from materials to processes.
Specialized instruments classify ink colors for precise color matching.
Even within the same batch of materials, slight color differences may still occur during actual production. To address this issue, Zhongqi Optoelectronics controls the process from the source, employing a dedicated ink color detector to test the optical properties of raw materials and grouping them according to precise standards to ensure consistent ink color across each module.
Refined production process to optimize ink color and smoothness
In addition to material and classification management, Zhongqi also adopts a series of refined processes in the actual production process to improve ink color consistency:
Patented self-developed optical materials
Employing a new generation of patented, self-developed optical materials ensures a high degree of consistency in the module's optical characteristics. This effectively improves the uniformity of ink color and gloss of the COB display when the screen is off, resulting in a more harmonious overall screen appearance.
Precision die bonding and welding technology
By utilizing high-precision die bonding equipment, the stability of LED chips is ensured, optical reflection differences are effectively avoided, ink color consistency is further optimized, and the overall quality of the display screen is improved.
Ultra-high flatness
Through meticulous manufacturing processes and strict tolerance control, we ensure that the modules are precisely aligned during installation, reducing minor height differences and effectively avoiding seam interference caused by uneven modules. This results in a smoother screen surface and a more advanced integrated visual effect.
Seamless splicing and factory pre-calibration
Before shipment, each COB module undergoes pre-assembly and calibration with professional optical equipment to ensure consistent ink color and precise seam matching.
This allows for efficient and precise installation of the modules on-site. The result is a smoother, more natural picture, bringing the overall viewing experience closer to that of a high-end home television.
3. Consistent ink color ensures a truly seamless COB large screen.
The consistent ink color of the COB modules not only ensures a premium feel when the screen is off, but also optimizes the color uniformity when the screen is on, making the spliced large screen truly seamless, like a perfectly integrated whole.
With its high-standard production management and meticulous manufacturing processes, Zhongqi Optoelectronics ensures that every COB module meets the industry-leading standard for ink color consistency, providing a superior product experience for high-end LED display applications.
The Way Forward <br /> In the future, Zhongqi Optoelectronics will continue to deepen its expertise in high-end LED direct-view display manufacturing and packaging technologies, constantly optimizing processes to bring customers higher quality and more stable and reliable LED display solutions.
