Why does Blu-ray still make movie fans fascinated in 2020?


Twenty years ago, most households had a DVD, and parents occasionally took us to the audio-visual store that rented the disc. However, as technology advances and people’s requirements for picture quality gradually increase, the next-generation storage format for DVD also came into being. One of them is the Blu-ray disc that we will discuss today.

Blu-ray disc uses a blue laser beam with a wavelength of 405 nanometers for reading and writing operations, so it is named after blue light. Blu-ray is just a storage medium, not a resolution format. What is the resolution of Blu-ray disc? In the DVD era, the highest resolution is only 480P. After Blu-ray appeared, it reached 1080P. In 2015, the Blu-ray disc alliance introduced Ultra HD Blu-ray. The capacity can reach up to 100GB and supports 4K UHD video with a resolution of 3840×2160. Thanks to the increase in Blu-ray capacity, more losslessly compressed audio formats such as PCM, Dolby TrueHD, and DTS-HDMA are also increasingly appearing in Blu-ray, further enhancing the viewing experience.

With the gradual popularization of 4K, UHD Blu-ray has not only improved its resolution, but the picture effect is getting closer and closer to the real experience of human eyes. In the UHD Blu-ray standard released by the Blu-ray Disc Alliance in 2016, it is required to support HDR10 and optionally support Dolby Vision. Compared with HDR10, Dolby Vision supports brightness up to 10,000 nits, while HDR is up to 1000 nits, which is a full ten times the latter; at the same time, Dolby Vision also supports 12bit color depth. Although the display effect of Dolby Vision is better, the fee is quite expensive.
