6 FAQs about [Principle of photovoltaic panel oled lamp]
What are the characteristics of OLED lighting panel?
OLEDs lighting panel is supposed to operate in harsh environmental conditions without any failure mode and degradation of luminous flux (maintaining constant light output with aging; Light sources lifetime: compact fluorescent lamps ~12,000 hr, linear fluorescents ~25,000 hr, and LEDs ~ 100,000 hr) with sufficient lifetime as displayed in Table 16.
What is the basic structure of OLED?
The fundamental device structure of OLEDs is very simple, consisting of an anode, some organic layers and a cathode. The OLED has several attractive features such as low driving voltage, high efficiency, wide color variation, and fast response speed. Need Help?
How effective is OLED panel light extraction?
Although OLED panel efficacy of much greater than 100 lm/W has been demonstrated in the laboratory, the low light extraction efficiency remains a key technical challenge. Integrating light extraction technology without disrupting the yield and stability of devices has presented a major challenge [ 143 ].
