Dolby laser or alpd laser has better viewing effect.

Dolby did achieve the ultimate in sound localization. The only thing that can compete with Dolby now is the laser. Compared with Dolby, the laser has an exclusive frame, returning to the Quan Huafu era of 1.44. The following is the full-text reprint of the comparison between the author ydx0 129 and laser IMAX: I think everyone is looking forward to this. After all, these two are the best representatives in the theater of commercial cinemas! Although the IMAX giant screen is very good, it is on the verge of elimination due to various well-known subjective and objective reasons, and large-scale RGB laser is also the trend of advanced commercial cinemas in the future. At present, the best brand cinemas with large RGB laser projectors are laser IMAX of IMAX Canada and Dolby Cinema of Dolby USA. The standard of these two cinemas is very high. Besides their own hardware, the most important thing is to have their own master film source to improve the picture effect. I have seen laser IMAX many times in Harbin Tailai Times Studios, and then I will make a simple comparison between the two best cinemas. In fact, the common characteristics of these two cinemas are bright brightness, clear picture and shocking sound! ! The subtle difference is that, first of all, when you watch it at Dolby Cinema in Dalian, to some extent, you feel brighter and the sound is more shocking. However, due to the disparity in screen size and cinema area, there is no comparability between the two aspects (in fact, the sound of laser IMAX is really shocking, and the advertisements are also shocking! ! And the picture is clear and bright! ); Thirdly, as I mentioned earlier, the glasses of Dolby Cinema are more comfortable than those of Laser IMAX. So in general, Dolby Cinema and Laser IMAX are on the same level (definitely better than ordinary digital IMAX), and they are both very good! But I think Dolby Cinema still has its own biggest advantage compared with laser IMAX. The biggest advantage of Dolby Cinema is the localization of sound, which is much stronger than IMAX. Dolby Cinema uses Dolby panoramic sound at the top, which is characterized by sound localization. The shock of sound and very good sound positioning make the sound effect reach the extreme! ! This is also the most obvious point that I think Dolby Cinema is superior to laser IMAX (laser IMAX pursues sound shock more), but the disadvantage lies in the limitation of film source and mixing effect. The biggest advantage of laser IMAX is to monopolize the frame, returning to the Quan Huafu era of 1.44. At the same time, IMAX has also introduced various IMAX cameras, especially film IMAX cameras (everyone should know the advantages of film IMAX cameras), which Dolby Cinema can't do (but Dolby has also introduced special cameras suitable for Dolby Vision). However, the disadvantage is that the shooting cost of IMAX cameras, especially film IMAX cameras, is too high, and the latter is noisy and the film cost is high, so there are not many so-called exclusive framing (of course, many film producers and distributors have signed exclusive framing agreements with IMAX companies, adding a lot of IMAX exclusive framing). Finally, laser IMAX and Dolby cinema go hand in hand, each with its own skill ~
