According to various embodiments, a back surface plate configured to form a back surface of an electronic device may include: a first glass part including a first pattern area including a pattern having a predetermined shape on a first surface; and a second glass part, at least a portion of which is disposed on the first surface of the first glass part, the second glass part including a first shape complimentary to the first pattern area, wherein the second glass part may have a color different from the color of the first glass part.

Techniques for making glass components for electronic devices are disclosed. The techniques disclosed herein can be used to modify a glass workpiece to form a three-dimensional glass component, such as a glass cover member. The techniques may involve reshaping the glass workpiece, fusing glass layers of the workpiece, or combinations of these. Glass components and electronic devices including these components are also disclosed.

According to one or more embodiments described herein, a three-dimensional laminate glass article may be manufactured by a process which may include heating a glass stack including at least two glass sheets that are unbonded with one another at a first temperature range, fusing the first glass sheet with the second glass sheet by heating the glass stack at a second temperature range, and shaping the glass stack. The first temperature range may be from about 150 C. to about 400 C. for a first period of time of at least about 5 minutes. The second temperature range may be from about 400 C. to about 1200 C.

The invention provides a white sintered glass-ceramic tile and a method for preparing the white sintered glass-ceramic tile. The white sintered glass-ceramic tile is a single fired tile with a glazed glass-ceramic layer and a porous glass-ceramic layer, wherein each layer is prepared using same starting raw materials. The method includes milling the starting raw materials to obtain a homogenous mixture. The homogenous mixture is melted and poured in water to obtain glass frits. The glass frits are milled and thereafter, sieved to obtain glass frit powder with particle size of below 100 micron (m). A mixture of the glass frit powder and one or more foaming agents is cold pressed to form a porous glass-ceramic layer. Thereafter, the glass frit powder is deposited on the porous glass-ceramic layer to obtain a glazed glass-ceramic layer. Finally, both the layers are fired together.

The present disclosure provides a method for manufacturing an aspherical prism and an aspherical prism. The method includes step S1, forming a prism and a lens into one piece to obtain a forming body glass by using a hot-pressing molding; step S2, adhering the forming body glass to a tooling, and performing a right-angle surface milling on the forming body glass according to a preset size while reserving a processing amount for a polishing process; step S3, adhering the forming body glass formed after the right-angle surface milling to an optical backing plate for polishing; step S4, cutting the forming body glass formed after the polishing; step S5, coating the forming body glass formed after the cutting; and step S6, inking the forming body glass formed after the coating. The method can improve the structural precision and processing efficiency of the aspherical prism.
