technical field

The present application belongs to the technical field of laser display, and in particular relates to a laser light source module and a laser display device.

Background technique

With the development of technology, more and more head-mounted devices appear in daily life, such as VR head-mounted display devices and AR head-mounted display devices. Head-mounted devices send optical signals to the eyes through various head-mounted displays, which can realize different effects such as virtual reality (VR), augmented reality (AR), and mixed reality (MR).

At present, the eye-tracking function of the headset greatly enhances the interactivity of the display, which is a major breakthrough compared with the previous passive imaging system. The wearer only needs to "wink" and can issue instructions without using hands. For example, looking to the right means turning a page, and the computer will automatically adjust the file down as you move your gaze down. Specifically:

1. Learning: Connect the course video to e-Vision, give children a completely closed learning environment, solve the problem of children's inattention, and improve children's academic performance.

2. Games: Connect PSP game console. You can clearly see various items on the ground in the game, which increases the fun and realistic effect of the game. All over the world, major manufacturers are scrambling to develop virtual reality games. Video glasses are a very important and indispensable part in virtual reality games: they allow you to truly experience the "immersive" feeling in a "sealed" environment.

3. Mobile phone: connect to a 3G mobile phone. No longer need to worry about finding the mouse on the Internet, or blurring the images of relatives and friends.

4. TV: It has wireless TV reception function, or directly connects with mobile TV CMMB, DVB-T or DMB-TH handheld digital TV. Such as used for passionate sports: When watching the Premier League or NBA, you no longer have to worry about whether it is a basketball or a human head.

5. Movies and TV: connect to MP4, MTV, concerts, and the latest hot thriller blockbusters to enjoy a complete visual feast.

6. Medicine: With the development of medical science and technology, equipment such as endoscopes has been developed on a large scale. In order to facilitate doctors' viewing and perception, video glasses have become an excellent display device.

7. Entertainment: With the development of science and technology, handheld entertainment devices that integrate entertainment, communication and games must become the direction of future development. In order to be light and portable, the screen of handheld entertainment devices cannot be larger than about 3 inches. It has become the bottleneck of the rapid development of this industry. The emergence of video glasses is the best way to break through this bottleneck. The 60-80-inch screen display effect allows you to play anything on your handheld terminal with shocking effects.
