Revo Power has 5.5-inch LTPS IPS display with a resolution of 1080 x 1920 pixels.The abbreviation LTPS means low-temperature polycrystalline silicon (LTPS) technology. It is one of the preferred technologies for big displays with large resolutions and pixel densities. The screen is protected by a Dragontrail 2 Glass. It is 30% harder than a standard Dragontrail glass and 8 times harder than the soda-lime glass (the standard one used in windows, bottles and so on). It has 2.5D curved edges, which perfectly with the fingers. Working with the display feels very pleasant, indeed. It is brilliant, fast and responsive. The colors are vibrant and crisp.
The screen of Revo Power looks very bright because of the high contrast ratio 1995:1. The contrast ratio is a property of a display system, defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black) that the system is capable of producing. A high contrast ratio is a desired aspect of any display. For Revo Power the figures are at 100% of brightness its white value is high – 552.705 cd/m2, which matched with the low black value – 0.277 cd/m2, end up in a contrast ratio of 1995:1. The screen has almost the same static contrast ratio at 25% of brightness, while at 75% and 50% it is around the 1700/1800:1 mark, and at 0% brightness drops twice to 930:1. This means that the colors look cold. The viewing angles are very good as well. A more interesting fact is that the display covers almost entirely correctly the sRGB color space with very light deviations. sRGB is a standard RGB color space created cooperatively by HP and Microsoft in 1996 for use on monitors, printers and the Internet, and subsequently standardized by the IEC as IEC 61966-2-1:1999.
