Based on the current shipment situation in the mobile phone market, has the company's traditional filter business basically maintained a stable performance level? Will there be any incremental performance in the future?

Crystal Optech's answer: The company's infrared cutoff filters account for about 30% of the global market share, which remains basically stable. The future growth of the filter business will mainly come from the iterative upgrade of traditional products. The company's absorption-reflection composite filter is an upgraded product of the infrared cutoff filter. The company is currently increasing the usage rate of Android customers. In the future, as the penetration rate of new products increases, it is expected to bring certain performance growth.
