What is laser scan display in computer graphics?

Answer 1

Oh, dude, laser scan display in computer graphics is like this fancy technology where a laser beam is used to draw images on a screen by scanning back and forth really fast. It's like a high-tech version of those old-school Etch A Sketch toys, but way cooler. So, yeah, it's basically a laser drawing stuff on your screen at lightning speed.

Answer 2

A laser scan display in computer graphics is a technology that uses a laser beam to draw images on a screen rapidly. The laser beam scans back and forth across the screen, illuminating phosphors to create the desired image. This method allows for high-resolution and high-speed image display, making it ideal for applications such as laser light shows and Virtual Reality displays. Laser scan displays are known for their precision and ability to produce bright, sharp images with smooth motion.

Answer 3

It is well known that conventional displays using phosphors or a lamp as a light source can express only about 30 % of all visible colors. Recently various efforts to expand color gamut of displays are being tried. The most efficient one is the laser display which is realized with lasers as the light source. Since lasers have the most saturated colors, the laser display has wider color gamut than that of the conventional displays using phosphors or a lamp. Its color gamut is almost three times wider than that of the conventional displays [1, 2]. So the trials to use lasers aslight sources have been continued. Figure 1 and Figure 2 show the comparison of color gamut between the conventional displays (sRGB) and laser display. With three lasers of RGB colors, up to 83 % of human visible color area can be expressed while color gamut is only 36 % in the conventional displays.
