OLED (Organic Light-Emitting Diode), organic light-emitting diode. Unlike LED materials, OLED is a surface light source, which is soft, thin, low energy consumption, less heat, no blue harm, and close to natural light. In addition, OLED with different substrates can be made into transparent, bendable and other new forms, which can break through the design limitations of current lamps and lanterns and can be applied to more fields.
OLED main structure
The basic structure of OLED is a thin, transparent indium tin oxide (ITO) with semiconductor characteristics, connected to the positive electrode of electricity, and another metal cathode, wrapped in a sandwich-like structure. The entire structural layer includes: hole transport layer (HTL), light-emitting layer (EL) and electron transport layer (ETL). When the power supply is to the appropriate voltage, the positive hole and the cathode charge will combine in the light-emitting layer to produce light, and the three primary colors of red, green and blue RGB will be produced according to their formulas, constituting the basic color.
OLED features: spectral near-natural light
Light has become an indispensable part of people's daily life, and the ultimate goal pursued by OLED light sources is equivalent to becoming natural light. Since OLED has a spectral distribution equivalent to natural light in a pure state without any treatment, OLED can be said to be an efficient green light source.
OLED features: thin and light (0.88mm)
The thickness of the OLED light-emitting panel is only 0.88mm. Due to their ultra-thin, ultra-lightweight, low power consumption, and use as a surface light source, OLED has a wide range of potential applications. Areas where OLED can be used in the future include windows or skylights, walls and ceilings, mirrors with lighting functions, floors, stairs, and other almost limitless possibilities. OLED lighting is environmentally friendly, mercury-free, and is an ideal material for next-generation lighting.
OLED features: flexible and bendable
The unique characteristics of OLED light source: Flexible (flexible and bendable), flexible characteristics increase the elasticity and imagination of the design, and various characteristics make OLED lighting and LED differentiated, conquering the lighting market that prefers surface light sources. It can be used to design unique, creative decorative luminaires that make a difference.
OLED features: no blue light hazard
Blue light (450nm) is a high-energy visible light, can directly penetrate the cornea and lens, directly to the macular area, accelerate the oxidation of macular cells, cause chemical damage to the retina, blue light to children's retina damage is more serious, and blue light is everywhere, a large number of daily life, the sun, fluorescent tubes, computers, liquid crystal displays all contain blue light. Therefore, blue light (HEV) has been shown to be the most harmful visible light.
OLED spectral analysis and detection confirm that OLED light source has no blue light hazard and is an ideal lighting source for health, especially for visual operation eye protection desk lamp, improve the working surface light environment, and care for eye health.
OLED features: high display index (Ra≥90)
Color rendering index (Ra), also called color rendering, refers to the degree to which the light source presents the color of an object. Color rendering is the relationship between the true color of a thing (its own color) and the light source displayed under a standard light source. Ra worth determining the method is to compare the 6169 test colors defined in the DIN8 standard under the standard light source and the tested light source, and the smaller the chromatic aberration, the better the color rendering of the measured light source. A light source with a Ra value of 100 indicates that things appear the same color under their light as they would under a standard light source.
OLED features: homogeneity ≥ 85%
The uniformity of illumination on the working surface is an important indicator of comfortable visual work lighting, and long-term, intent, and concentrated attention to the area with uncomfortable factors will cause obvious eye fatigue or imperceptible damage.
