Advantages of COB light sources in consumer electronics backlight display modules

‌The advantages of COB light sources in consumer electronics backlight display modules mainly include the following aspects‌:

‌High integration and flexibility‌: COB light source technology (Chip on Board) directly integrates multiple LED chips on a circuit board. Compared with the traditional SMD (surface mount device) packaging method, COB technology has higher integration and photoelectric performance have been significantly improved. This highly integrated design enables COB light sources to provide customized lighting solutions for various backlight application scenarios.

‌High light efficiency and uniform illumination‌: COB light sources usually have higher light output efficiency, can provide brighter light, while achieving uniform lighting effects, reducing shadows and light spots, making lighting more comfortable‌2. In addition, the light-emitting surface of the COB light source is linear, and the light emitted is uniform and has no spots, making it suitable for backlight display modules that require high illumination uniformity.

‌Miniaturization and diversified applications‌: COB light sources are small in size and can be easily integrated into various lighting equipment, making them suitable for occasions with limited space. Its diverse application scenarios include commercial lighting, residential lighting, automotive lighting, etc. Especially in backlight display modules for consumer electronics products, COB light sources can provide more compact and efficient solutions.

‌Long life and low maintenance cost‌: Compared with traditional light sources, COB light sources have a longer service life, reducing replacement frequency and maintenance costs. Its efficient heat dissipation design and stable circuit design further extend the service life of the light source‌.

‌High color rendering, healthy and environmentally friendly‌: Many COB light sources can provide a high color rendering index (CRI), making the lighting effect more natural and realistic. In addition, the COB light source uses heat sink process technology to ensure that the LED has an industry-leading thermal lumen maintenance rate (95%), is healthy and environmentally friendly, and has no light spots, making it suitable for consumer electronics products that require high lighting quality.
