led display is a good lamp bead or a good patch

• Brightness and color ‌ : the light of LED lamp beads is more uniform and the color is stable; The patch lamp may have light occlusion, and the uniformity is slightly lower.
• ‌ production process and cost ‌ : LED lamp beads production process is complex, high cost; The chip lamp adopts PCB process and the cost is relatively low.
• ‌ life and stability ‌ : LED lamp bead long life, good stability; The stability of the patch lamp is also good, but long-term use may cause problems.
• ‌ installation and use ‌ : LED lamp bead installation is more complex, need professional operation; The patch light is easy to install and suitable for batch use.
• ‌ Special needs ‌ : If you need a thin, flexible display, LED film screen (a special form of patch) may be more suitable.

What is the life of the lamp bead and the patch respectively?

‌LED bead life:

• ‌ theoretical life ‌ : The theoretical life of LED lamp beads in an ideal environment can reach 100,000 hours.
• ‌ actual life ‌ : affected by the use of environment, heat dissipation conditions, driving power supply and other factors, the actual life is usually between 30,000 and 50,000 hours.
• ‌L70 life ‌ : the L70 life of the LED lamp bead (the luminous brightness is reduced to 70% of the initial brightness) can also reach tens of thousands of hours, which means that the brightness can still be maintained at a high level ‌ during this time.

‌ chip lamp bead life:

• The life of the chip lamp bead is also affected by many factors, including the use environment, heat dissipation design, driving current and voltage.
• Under normal conditions, high-quality patch lamp beads can also continue to glow for several years or even longer.
