DOB uses colloid osmotic pressure technology in optical films, based on high-end LED module packaging research to create a high-definition, high-reliability LED module packaging method. By independently developing high-strength, high-reliability polymer nanomaterials (silicone plastic resin SPE) powder raw materials, a solid elastic colloid is formed. Through positioning fixtures, the thickness consistency of the colloid on the lamp is ensured, guaranteeing a consistent dark color, repairability, and a scar-free surface.

Low stress, no yellowing: Uses elastomer injection layer that adjusts stress with temperature changes, protecting lamp beads from impact or harsh transportation conditions.
Extremely low internal stress, the middle layer is an elastomer, using temperature change technology, as the temperature changes, the elastomer injection layer will adjust the stress according to the temperature so that it can always protect the lamp beads. The surface is highly protected, achieving true shockproof and anti-collision. It can withstand harsh transportation or violent impact environments, avoid dead lights or falling lights, and reduce later maintenance.
Scratch-resistant and wear-resistant: Tested using a screwdriver scratch test—DOB packaging showed no abnormality, unlike GOB packaging.Test object: GOB packaging process productsTest method: Use a screwdriver to scratch the surface of the two products with the same forceTest results: There are scratch marks on the surface of GOB packaging process productsThere is no abnormality on the surface of DOB packaging process products.

High and low temperature resistance: The elastic adhesive layer adjusts stress with temperature fluctuations. Passed 200 rounds of hot and cold shock tests from -40°C to 85°C without deformation or cracks.
The middle layer is an elastic colloid, the light-transmitting adhesive layer is based on silicone plastic SPE, which has good elasticity and toughness in the solid state; using temperature change technology, this elastic adhesive layer will adjust its stress according to temperature changes, making it always Protect lamp beads with extremely low internal stress, under high-intensity pressure. It has extremely low deformation under strong pressure and will never crack. It can withstand 200 rounds of hot and cold shock tests from -40C to 85C. lt's adaptable to most common environments and is not always cold. The deformation is small at low temperatures the ambient temperature returns to normal temperature. It can be restored after being put down, and it will not deform or expand at high temperatures.
No blue light, no ultraviolet: Features an anti-blue light layer that reduces blue light exposure, ensuring less than 10% yellowing over 72 hours and maintaining stable LED module colors for over 5 years.
An anti-blue light layer is provided between the light-transmitting adhesive layer and the light-transmitting film, and an anti-blue light layer is provided on the upper surface of the light-transmitting film. After adding anti-blue light performance, the product's ultraviolet resistance strength: the yellowing will not exceed 10% over 72 hours, which can ensure that the product will not yellow or turn white after long-term use (>5 years). lt effectively reduces the blue light of LED modules, which is beneficial to human eye health. lt has strong light transmittance and super consistency.lt can achieve the same appearance color for thousands to tens of thousands of square meters, with consistent light emission and no display appearance color difference.
Non-reflective surface: Uses a matte finish with consistent glue thickness (<0.1mm), ensuring no visible splicing lines or reflections.
The principle of height limit is used to ensure the consistency of each module. The thickness of the glue layer is uniform and consistent. The flatness of the glue surface is not higher than 0.1MM. The difference in coating of the same batch of modules is not more than 5 wires, and the modules will not change with each other. lt becomes different in thickness due to deformation, and extremely fine splicing lines, and the surface is matte and roughened and does not reflect light.
UV resistance and low attenuation: Maintains LED brightness and color accuracy, with a 168-hour attenuation rate of <2%.
All-round sealing protection maintains a stable working temperature environment for LED devices. High -quality raw materials have good heat dissipation functions. The 168H attenuation rate is <2%. lt will not reduce the brightness or color after long-term work, and maintain the display protection of the LED display. authenticity, effectively improving product relia bility.
