However, some shortcomings of Micro LED technology also hinder the comprehensive commercial breakthrough of this technology. Because Micro LED provides performance including small size, low power consumption, excellent brightness and energy efficiency, higher contrast and color saturation, ultra-high resolution, flexibility and good reliability. Such Micro LED devices are usually used in small-size screens including tablet computers, smart phones,
and smart watches. Micro LED screens are composed of tiny pixels that can generate green, blue, and red light, and some steps in manufacturing these pixels can easily cause damage to their fine nano-scale structures, which in turn can lead to loss of light intensity. Picosun believes that Micro LED is a big challenge for existing display technologies including liquid crystal displays, OLEDs and traditional LEDs.According to foreign media reports, the Picosun Group, a leading supplier of industrial atomic layer deposition (ALD) wholesale high bay led lights thin-film coating technology,
said recently that it has improved the performance of its Micro LED by using a technology called ALD passivation. At present, many leading electronics manufacturers and institutions in the world are stepping up research and development of Micro LED. Picosun said that it has been confirmed that ALD ‘can effectively repair these structural damages, not only can restore the lighting intensity, but also increase it to a higher level
After the above conditions are determined, the driving conditions for each single LED have basically been set, and the overall power of the lamp will be fixed accordingly.There are some advanced models on the market that provide environmental adaptation functions, allowing detection and automatic adjustment of output voltage and current when driving, and enter the constant current area after the lamp reaches a stable operating state.8V.
There are also many possibilities for other models. Figure 4 V-T curve HVGC’s constant power series also have similar functions. The power supply can automatically reduce the current and increase the voltage up to 120% to ensure that the lamp can be turned on smoothly at low temperatures. Users can temporarily reduce the current and increase the maximum output voltage through dimming control. 3.48V b.3.
