The liquid glass surface is crafted to impress using Optical Spectrum Hybrid Deposition. By layering highly-refractive precious minerals across the phone’s back cover, we’ve created stunningly vivid new colors that transforms light with every movement you make. The new seamless curved look of HTC U11 is achieved through heating and then bending the glass using extreme pressure. It’s a tricky process to master, but the resulting unique all-around 3-axis symmetry produces a phone that is slim no matter which way you hold it. With 3D glass on both front and back, it’s not only beautiful but more secure and comfortable to hold. HTC U11 has a 5.5" 3D glass screen designed to preserve the authenticity of the image. With our best display and true-to-life color reproduction, we provide you a purer full-framed viewing experience. Our display avoids the cropped pictures or distorted colors at the edge that are the results you can expect from a curved screen.
