What is COB LED Display Screen?
COB LED display screen is a type of LED display screen that uses flip-chip COB technology to pack multiple LED chips on a single substrate, forming a single module. A flip-chip COB module consists of three segments of red, green and blue (RGB) colors, which are soldered directly onto the substrate without any packaging or wire bonding. The LED chips are placed very close to each other, creating a high-density pixel arrangement that produces high-resolution images on the LED screen.
How does COB LED Display Screen work?
COB LED display screen works by using an electric current to excite the electrons in the LED chips, which then emit light of different wavelengths according to their color segments. The light from the LED chips passes through a layer of epoxy resin that covers and protects them from external damage. The epoxy resin also acts as a lens that focuses and diffuses the light evenly across the surface of the LED screen. The light then reaches the viewers' eyes, forming a vivid and clear picture.

COB LED display screen has several advantages over other types of LED screens, such as SMD (Surface Mounted Device) or DIP (Dual In-line Package) LED screens. Some of these advantages are:
- High contrast and brightness: COB LED display screen has no light blocking or reflection between the LED chips, resulting in a high contrast ratio and brightness level. The epoxy resin layer also enhances the sharpness and clarity of the images.
- Wide viewing angle: COB LED display screen has a wide viewing angle of almost 180 degrees, with consistent brightness and color contrast from different perspectives.
- Shock resistant and waterproof: COB LED display screen has a strong resistance to shock, vibration and impact, as the epoxy resin layer protects the LED chips from physical damage. It is also waterproof and dustproof, making it suitable for outdoor and indoor environments.
- Eye-friendly: COB LED display screen has a lower blue light emission than other LED screens, which reduces eye strain and fatigue even after long exposure to the screen.
What's more:
Better color reproduction than traditional SMD based LED screen
more energy efficient, less power consumption
Sharpened imaging and premium visual experience for pictorial representation
Higher resolution due to direct encapsulation of LED chips to the PCB board ----- pixel pitch starts from 0.93mm
