The laser has three characteristics: good directivity, good monochromaticity, and high brightness. It is the basis of high-fidelity images for laser pointer televisions. The goal of the development of television technology is to reproduce high-fidelity images, which have three elements: dual high-definition, large color gamut, and true 3D. Laser TV can raise the three elements of television to the limit of the human eye. It can be said that it has reached the highest level of television technology. Its geometric resolution will increase by more than 9 times, the number of colors will increase by more than 4000 times, and the color gamut coverage will increase by more than 3 times. Color saturation is increased by more than 8 times, and parallax 3D becomes true 3D. Laser TV is the best way to achieve high saturation and large color gamut TV. Laser TVs have much higher color gamut coverage than existing color TVs. Therefore, when watching the laser pointer TV, the color perceived by the human eye is 3 times richer. The color perceived by the human eye should also be three times brighter.
From the beginning, the development of 650nm red laser diodes has been widely used in the current demonstration work. So a red laser pointer was developed, which has been widely used in teaching, PowerPoint presentations, reading, business, and conferences. The red laser pointer is also a very good dog or cat toy because of its low visibility to the human eye and emits a bright red laser beam.
Once the user uses the red laser pointer for laser beam emission, the direct emission of the laser beam always has better performance. It obtains less heat radiation in continuous laser pointing work. Once the operating temperature is much higher than expected, the 1000mw green laser beam still maintains its high stability and high reliability. The temperature during working hours is much higher than expected, and the power can be automatically turned off. According to the special design of the on-board electric drive protection circuit, the 650nm red laser diode is still perfectly protected.
