It is understood that each laser pointer TV will use hundreds of red, green and blue laser chips. The cost of laser chips currently accounts for about 40% of the total machine cost. In addition, optical and imaging DMD projection chips also occupy the bulk. Technology is in the hands of foreign companies, and it is imminent to reduce the cost of chips. It can be said that the first domestic 8W-level coupling module developed based on domestic red light LD chips came out. It means another important step towards the desired goal. This will accelerate the industrialization process of laser pointer display.
Various lasers have a key switch locking mechanism that prevents the laser from being turned on (even if the battery is charged) unless the key is turned on and activated. Now you can remove the key afterwards without using the laser while the key is hanging. This is a great security feature for small children and those who do not want unauthorized people to use the key. laser.
