LCD itself will not light, you want to display data and images, you must use a white backlight. White light backlight is generally composed of a number of white LED, LED number determined by the size of the screen, the drive is mainly used inductor boost DC / DC to achieve, LED series together, the same drive current to ensure that each LED brightness , The same color.
With the rapid development of power inductors liquid crystal displays and smart phones, conventional small-size ferrite power inductors can not meet the needs of the backlight drive current, but with higher saturation characteristics of the iron core power inductors and one forming inductance, because the alloy material , In the step-up DC / DC converter to withstand higher voltage, the product prone to pressure failure, the use of backlight drive in the presence of a greater risk.
In order to cope with the risk of iron core winding power inductor in the backlight boost application, Shenzhen Sunlord Electronics Co., Ltd. combined with its own years of winding power inductor and core material development experience, based on the original WPN series, developed WPN -HS series of high pressure level winding iron powder core power inductors.
power inductors manufacturer use thesurface coating technology, through the automated coating equipment, high temperature, high insulation resin evenly coated on the iron core surface, to further improve the product pressure, corrosion resistance, suitable for all kinds of large demand for inductor current Backlit boost circuit.
Features
Small size, with high resistance to current capacity.
Resin evenly coated core, with a high pressure level and corrosion resistance.
Fully automated production, high quality, good consistency.
