In the visual performance of LED displays, the ink consistency of COB modules is one of the key factors determining the overall appearance 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 up, which can directly affect the overall visual experience of the large screen.
1. Why is ink consistency important?
A screen with consistent ink color presents a seamless black visual effect when the screen is turned off. On screens with poor ink color, there may be color differences between modules, creating a noticeable "mosaic" effect that affects the overall and high-end display.
In LED direct display products, the impact of uneven ink color is far beyond imagination:
Affects the sense of integration in splicing
A screen with large color difference will show obvious module boundaries when it is black, which will have a negative impact on contrast and make the screen surface look like a mosaic wall, which is not aesthetically pleasing and greatly reduces the overall display effect.
Affects the restoration of bright screen color
Even if the LED chip itself emits the same color, if the reflectivity of the screen surface is different, it may still cause brightness and chromaticity deviation after lighting up, resulting in uneven color distribution of the display screen.
Therefore, improving ink consistency can not only optimize the aesthetics in the off screen state, but also ensure color uniformity after lighting up, making the entire picture more coordinated and natural.
2. How to achieve a visual experience of consistent and seamless ink color?
To achieve high standards of ink consistency in COB modules, strict control is required in multiple aspects such as material selection, production processes, and assembly accuracy to ensure that each module reaches the same visual level. This cannot be separated from the refined management of the entire chain from materials to processes.
Specialized instrument for ink color classification, accurately matching colors
Even for materials from the same batch, slight color differences may still occur during the actual production process. To solve this problem, TBC LED controls from the source and uses a dedicated ink color detector to detect the optical properties of raw materials, grouping them according to fine standards to ensure consistent ink color effects for each module.
Refine production processes, optimize ink color and smoothness
In addition to material and classification management, TBC LED has also adopted a series of refined processes in the actual production process to enhance ink consistency:
Patent self-developed optical materials
Adopting a new generation of patented self-developed optical materials to ensure highly consistent optical characteristics of the module. This can effectively improve the ink uniformity and glossiness of COB display screens in the off screen state, making the overall appearance of the screen more coordinated.
Precision solidification and welding technology
Utilizing high-precision solidification equipment to ensure the stability of LED chips, effectively avoiding optical reflection differences, further optimizing ink consistency, and improving the overall quality of display screens.
Ultra-high flatness
Through precise manufacturing processes and strict tolerance control, the module is accurately aligned during installation, reducing small height differences and effectively avoiding seam interference caused by module unevenness. This makes the screen surface smoother and presents a more advanced integrated visual effect.

Seamless splicing and factory pre calibration
Each COB module undergoes pre assembly and calibration with professional optical equipment before shipment to ensure ink consistency and precise matching of seams.
Enable efficient and precise installation of modules on actual installation sites. The final presentation presents a smoother and more natural visual effect, making the overall experience closer to high-end home TVs.

3. Consistent ink color, making the COB screen truly "integrated"
The COB module with consistent ink color not only ensures a high-quality texture when the screen is turned off, but also optimizes the color uniformity after lighting up, making the spliced large screen truly seamless, like a natural whole.
TBC LED ensures that every COB module meets industry-leading ink consistency standards through high standard production management and refined manufacturing processes, providing a more outstanding product experience for high-end LED display applications.
