COB SMD technology | Different environmental impacts

SMD

COB SMD technology uses an external power supply to drive RGB three-color lamp beads to emit light, so there are problems such as environmental pollution, energy waste, and light pollution.

Especially in large outdoor displays, COB SMD displays can generate a lot of heat and noise, causing adverse effects on the surrounding environment and people. Moreover, SMD screen technology uses non-degradable materials such as metal and plastic, which is difficult to recycle and process, causing long-term harm to the environment.

OLED display technology uses self-luminous organic materials, so it has the advantages of environmental friendliness, energy saving, and low light pollution. Especially in small indoor displays, OLED displays can achieve low power consumption and low noise working modes, causing little impact on the surrounding environment and people.

Moreover, OLED display technology uses organic and degradable materials, which is easy to recycle and process, causing little harm to the environment.

Different Market Prospects

COB SMD technology occupies a dominant position in the current LED display market due to its advantages of maturity, stability, low cost, and wide application. Especially in large outdoor displays, COB SMD technology still has a strong competitiveness.

However, as users have higher and higher requirements for display effects and functions, COB SMD screen technology is also facing challenges such as innovation bottlenecks and market saturation, and requires continuous technological improvements and product upgrades.

OLED display technology has great development potential in the future LED display market due to its advantages such as high definition, high contrast, low power consumption, and flexibility, especially in small indoor displays. OLED display technology will become a mainstream trend. However, OLED display technology also faces challenges such as short life, high cost, and low production capacity, and requires continuous technological breakthroughs and production capacity.

The difference between COB and LED is cob-packaged led display and SMD packaged led display

What’s the difference between them and what do they’ve in common?

For LED displays, both COB and SMD are packaging styles. COB directly packages the light- emitting chip on the PCB board, while SMD refers to face underpinning. Both displays have their own advantages and disadvantages

SMD packaged LED display– Advantages

  1. Can produce displays that are thinner, lustrously, and clearer than LCDs
  2. Power consumption is10/1 of TV display
  3. High brilliance
  4. Viewing angle 160 °
  5. High refresh rate, discrepancy, better display and better product performance
  6. Can be viewed typically under strong light
  7. The response of a single element is 1,000 times that of a TV screen
  8. 30 °C- 80 °C can be used typically
  9. Waterproof, humidity- evidence, anti-static, dust- evidence, lightning- evidence, anti-static
  10. There are numerous types of distance, suitable for colorful operation surroundings
  11. Colorful shapes can be assembled at will
  12. Long life (further than 10 years)

SMD packaged LED display- Disadvantages

  1. The brilliance is too high and long-term viewing can fluently beget eye fatigue.
  2. It feels coarse when viewed from a close distance.
  3. Beacon globules may be damaged during transportation.
  4. The heat dispersion capacity isn’t strong enough
  5. There’s a big difference between the distances
  6. delicate to clean

COB packaged LED display– Advantages

  1. Small distance, smooth screen, and clearer display (preferred below)
  2. The picture is soft and bright, and it won’t hurt your eyes when you watch it for a long time
  3. Differ rate 100001, superior picture quality
  4. Refresh rate ≥ 3840Hz, a symbol of high quality among analogous products
  5. Anti-collision and impact resistance, the cargo- bearing capacity is further than 5 times that of the LED display, and it isn’t hysterical of collisions, broken lights and other problems during transportation
  6. Good heat dispersion capability, heat is snappily dissipated directly through the PCB board
  7. Effectively suppress moiré patterns
  8. Super large viewing angle 170 °
  9. Waterproof, humidity- evidence, anti-static, dust- evidence, lightning- evidence, anti-static, anti-collision
  10. Can be used typically at-40 °C- 80 °C
  11. Easy to clean
  12. Long life (further than 10 times)
COB packaged LED display–disadvantages
  1. High price
  2. The technologies of each enterprise are uneven.
  3. The screen appearance isn’t as good as LED small pitch
  4. The product process is different from SMD Screen packaging, and the metamorphosis cost is high.

In its current form, a large part of the reason why cob displays haven’t been well vulgarized is due to the transition from outdoor SMD screen packaging. The original outfit will be wasted, and cob technology is veritably different for enterprises. And at last it time to say goodbye. I hope the content (is a detailed preface precisely collected by editor for mustangled Advertising) can be helpful to you.
