The era of bulky bezels is over. As TVs and high-end monitors shrink to millimeter-thin profiles, traditional SMD backlighting is hitting a ‘physical wall.’ Visible light dots and uneven heat distribution are no longer just minor flaws—they are deal-breakers for modern display quality. This is where COB LED strips are not just an alternative, but a revolution.
This is where COB LED strips are changing the game. By placing multiple LED chips directly onto the board, COB technology creates a continuous light surface that fits today’s display standards much better. For display manufacturers and integrators, this shift is not just about lighting—it directly affects panel uniformity, lifespan, and overall product value.
Raymates, a professional LED strip manufacturer with over a decade of industry experience, has been developing COB LED strip solutions specifically suited for backlighting in TVs and monitors. From large panels to ultra-slim displays, these products are designed to meet real production needs rather than lab-only specs.
Why Is COB Technology Changing TV and Monitor Backlighting?
As display sizes increase and bezels shrink, backlighting has less room for error. COB technology addresses several long-standing pain points at once.
Before diving into the technical reasons, it helps to look at how COB differs from traditional LED packaging.
| Feature | Traditional SMD Strip | Raymates COB LED Strip |
| Light Uniformity | Visible dots (requires thick diffusers) | Continuous, 100% dot-free |
| Thermal Efficiency | Point heat source (high stress) | Distributed heat dissipation |
| Thickness | Bulkier (due to LED lenses) | Ultra-thin, low profile |
| Flexibility | Limited bending radius | High flexibility for curved screens |
Seamless Light Uniformity Without Visible Dots
One of the biggest complaints with older SMD backlighting is the “dot effect.” Even with diffusers, light points can still show through, especially on bright or white screens.
COB LED strip for TV backlight units (BLU) eliminate this issue by design. The chips are packed tightly and coated with phosphor, creating a smooth line of light. In TV and monitor backlighting, this means cleaner whites, fewer dark zones, and better edge consistency. Raymates COB strips are built to maintain this uniform glow across long runs, which is critical for large panels.
Higher Luminous Efficiency in Slim Display Designs
Slim displays leave little space for optical layers. Every millimeter matters. COB LED strips offer high light output from a compact footprint, allowing manufacturers to reduce the thickness of light guides and diffusers.
Raymates supports multiple voltage and power options, making it easier to balance brightness with energy use. This flexibility is useful for brands targeting different screen sizes without redesigning the entire backlight system.
Improved Thermal Stability for Long Screen Lifespan
Heat is a silent killer for displays. Poor thermal control leads to color shift, brightness drop, and early failure. COB technology spreads heat more evenly across the strip. COB packaging allows for a much larger thermal contact area compared to SMD. While traditional SMD 2835 LEDs often struggle with heat dissipation in confined 5mm spaces, COB designs can reduce the junction temperature by 15% to 20%. Combined with Raymates’ controlled manufacturing process and board material selection, this helps reduce hot spots. The result is steadier performance over time, especially for screens that stay on for long hours.
How Do COB LED Strips Improve Display Image Quality?
Backlighting quality has a direct impact on how content looks on screen. It affects contrast, color accuracy, and viewing comfort. When compared to standard SMD 2835 or 3014 LED strips, the COB strip light’s dot-free performance significantly reduces the need for thick diffuser layers.
Transitioning from structure to visual results, COB LED strips improve image quality in ways that are easy to see, even without technical tools.
Consistent Brightness Across the Entire Panel
Uneven brightness is one of the fastest ways to make a screen look cheap. Edge darkening or patchy light ruins the viewing experience.
Raymates COB LED strips provide stable light distribution along the panel. This consistency helps TV and monitor manufacturers maintain uniform brightness from corner to corner, even in larger displays where traditional strips struggle.
High CRI for More Accurate Color Rendering
Color accuracy matters more than ever, especially for monitors used in design, editing, or gaming. Raymates COB strips are available with high CRI options, helping displays show more natural colors. Skin tones look more real, gradients feel smoother, and color shifts are reduced. This is a clear advantage for mid to high-end displays that compete on picture quality.
Flicker-Free Output for Eye Comfort
Flicker is not always visible, but users feel it. Long viewing sessions can cause eye strain and fatigue if the backlight is unstable. COB LED strips from Raymates are designed to work smoothly with compatible drivers, delivering steady light output. This helps meet flicker-free requirements in modern TVs and monitors, especially for office and home use.
Why Are COB LED Strips Ideal for Ultra-Thin TVs and Monitors?
Our COB solutions comply with the IEC 62471 photobiological safety standards, ensuring that the blue light hazard is minimized—a critical factor for high-end monitor certification. As industrial design pushes displays thinner each year, backlighting must adapt. From a mechanical and structural point of view, COB LED strips offer clear advantages that fit ultra-thin designs better than older solutions.
Compact Chip-on-Board Structure
COB packaging removes the need for bulky LED lenses. The light source stays flat and low-profile, making it easier to integrate into thin backlight modules.
Raymates offers COB strips with board widths ranging from very narrow to more robust options, supporting different structural needs without forcing design compromises.
Flexible Board Width Options for Narrow Spaces
Not all backlight areas are the same. Edge lighting, curved corners, and narrow channels all require flexibility. The Mini Size COB Strip from Raymates is designed for tight spaces inside slim monitors and TVs. Its narrow width makes installation easier while still delivering uniform light.
Reduced Optical Components Requirement
Because COB strips produce smooth light on their own, fewer diffusers and optical layers are needed. This simplifies assembly and reduces material cost.
For manufacturers, this also means fewer variables during mass production. Fewer layers often lead to more stable results across batches.
Which Raymates COB LED Strips Fit Different Backlighting Needs?
Different displays require different backlighting approaches. Raymates offers COB LED strip options that match common TV and monitor scenarios.
Before selecting a product, panel size, brightness target, and design layout should be considered. The following options cover most mainstream needs.
Super Long COB Strip for Large TV Backlight Panels
Large TVs require long, stable lighting runs. Frequent connection points increase failure risk and installation time. The Super Long COB Strip supports extended lengths with stable output, making it suitable for large TV panels. Fewer joints mean better reliability and cleaner assembly.
Mini Size COB Strip for Slim Monitors and Edge Lighting
Ultra-thin monitors leave little room for error. The Mini Size COB Strip fits narrow channels while keeping brightness even across the screen. This option is often chosen for edge-lit designs where space is limited but visual quality still matters.
Colorful COB Strip for Dynamic Display and Ambient Backlight
For gaming monitors and modern TVs, ambient lighting has become part of the experience. The Colorful COB Strip supports RGB effects while keeping the same smooth light surface COB is known for. It works well for dynamic backlighting and visual accents behind displays.
