Like LG's 440ppi pixels per inch 1080P display, HTC's J Butterfly also has a resolution of 440ppi pixels per inch, 1080P, but this data was quickly refreshed by Japanese companies. According to the report of Japan's Nikkei Tech-On, Japanese display companies have successfully developed a 9.6-inch display with Ortus technology, with a resolution as high as 3840 2 160. At the same time, this mobile monitor also set a new record of pixels per inch, reaching 458ppi. At the same time, the company is also very proud to announce that the world's smallest 4K resolution panel was also developed by them. Although the viewing angle and effect of 160 are better than that of IPS panel, the screen covers 72% of NTSC color gamut, which can fully show the sRGB effect.
