the vertical axis is energy use

Such a light beam in the way of lighting and control design of our optical system has been lighting the way some revolutionary changes. At the same time, an excellent degree of polarization of laser light source, a km on the degree of polarization, such that the degree of polarization and polarization for LCD display technology, it can be significant savings in raw materials, and its contrast than the current degree of polarization to much higher. Light bulbs and LED light source with a completely different, because the optical properties of laser light, in a small chip can achieve a high light utilization efficiency. The wavelength of  laser pointer  should be in details. The wavelength of laser pointer can be various. The teacher has bought more laser pointer . This graph abscissa is the chip size, the vertical axis is energy use. Lighting light bulbs to use with the chip size decreases, its energy utilization efficiency is relatively low. For the laser, the basically unchanged, because the direction of the laser is good. Compared the number of applications, such as micro-display rear projection or projector or movie projector, even if such a monster for the movie projector, if as a million people if the display, then the required laser light power is nothing but 140 W, if the development of the laser device is good enough, it needs to consume only 25 watts of electrical power, so low power consumption and high efficiency, in fact, expanded the number of high-energy, large-screen display or in a variety of applications applications of the application. The student needs more laser pointer .
Display industry is a modern high-tech industry, an important component of modern information society is an important foundation for the development of industry. After a black and white display technology display, color display to the digital display, the program has completed the transition to high-resolution, digital changes. However, the current color space display products covered by the human eye can only identify the color space of 31.8%, difficult to truly restore the natural color, it has become important to further improve the display quality of the barrier. As a new generation of display laser display technology, inherited all the advantages of digital display technology, based on the high saturation of red, green and blue color laser light source as a display, a display technology to solve the long-term difficult to solve large-gamut color reproduce the problem.
