1. size control: the key of micro-LED micro-vibration process lies in the precise control of micro-size. The size of LED chips is between tens and hundreds of microns, or even smaller. This technology requires highly precise processing equipment and technology, and micro-vibration technology needs to ensure the uniformity of the size of each micro-LED chip to ensure the consistency and stability of the display effect.
2. Packaging technology: micro-LED micro-vibration technology also needs supporting packaging technology to package the micro-vibration chip into a suitable display device. Packaging technology involves chip packaging structure design, packaging material selection and packaging technology. Due to the small size and large number of micro-vibration chips, high precision and high efficiency are required in the packaging process.
