Abstract: Disclosed are a method and system for eliminating yellow ring phenomenon occurring on the white light emitting diode (LED) based on a blue light chip exciting yellow phosphor powders and having a packaging surface enclosing thereon. Lightspot images are repeatedly acquired outside the white LED, and then each analyzed to see if the yellow ring still exists on a lightspot. If yes, a further atomization process is performed on the packaging surface of white LED, until the acquired and analyzed image shows no yellow ring exists. A lightspot-by-lightspot basis is used in the yellow ring elimination task. In the image analysis, a look up table may be provided in advanced or established at the same time simultaneously with the yellow ring elimination task. The atomization performed on the lightspot may also consider a width issue.

Abstract: A virtual reality telescopic observation system of an intelligent electronic device. The virtual reality telescopic observation system includes an electronic device arranged for displaying a virtual image, an engagement slot arranged for movably embedding the electronic device therein and a virtual reality telescopic optical module, including at least one optical lens installed corresponding to the electronic device, arranged for projecting the virtual image displayed by the electronic device into the virtual reality telescopic optical module, such that a viewer views the virtual image displayed by the electronic device from the virtual reality telescopic optical module. Wherein, when the viewer performs a virtual reality telescopic observation, the angle, distance and position of the virtual image displayed by the electronic device are adjusted according to a changing of the field of view made by the viewer.
