A method of forming a glass article includes providing a first glass sheet. The first glass sheet is heated to a temperature suitable for shaping. The first glass sheet is deposited on a first bending tool. An edge portion of the first glass sheet is disposed over a shaping surface of the first bending tool. The shaping surface of the first bending tool is configured to provide in the first glass sheet a compression area and a tension area. The first glass sheet is shaped on the first bending tool and the compression area is formed in the edge portion of the first glass sheet. The compression area includes a first portion and a second portion. The first portion has a width which is greater than a width of a second portion.

Display cover glass includes a glass substrate. The glass substrate has a first panel and a second panel. An angle formed between the first panel and the second panel. The first panel has a first display area provided with an arbitrary first point. The second panel has a second display area provided with an arbitrary second point. The color difference value ΔE between the first point and the second point is less than or equal to 17 when the viewing angle difference between the first point and the second point is 10-60 degrees. The first panel and the second panel make it possible to display driving information, such as a navigation interface, and an operation interface in the two display areas respectively so that the driver of a means of transport can read the information clearly and use the operation interface with ease.

A system for acquiring surface data from one of the surfaces of a curved glass sheet and developing a surface definition of the glass sheet includes a conveyor for conveying the glass sheet in a first direction, at least one display projecting a preselected multi-phase non-repeating contrasting pattern, and at least one camera, each one of the cameras uniquely paired with one of the displays. The system may also include a control programmed to execute logic for controlling each of the camera/display pairs to acquire the desired images, and logic for analyzing and combining the data acquired by the cameras to construct a definition of the surface of the glass sheet.

A method of etching a display panel for manufacturing a curved display device comprises the steps of: applying a masking ink in a manner of immersing a non-etched portion of a display panel into an ink reservoir, which contains the masking ink, in order to protrude the non-etched portion from the display panel; curing the masking ink coated on the non-etched portion of the display panel; etching the display panel to reduce the thickness of the display panel by coating an etching liquid onto the display panel on which the masking ink is cured; and removing the masking ink from the etched display panel with a solvent, which dissolves the masking ink.

Emobidments of a curved glass article are disclosed herein. The curved glass article includes a glass sheet first and second major surfaces. The glass sheet is bent to define a curved region disposed between flat sections. The curved glass article also includes a carrier adhered to the glass sheet. The carrier includes longitudinal strips and lateral strips. The longitudinal strips define the radius of curvature of the curved region. The lateral strips extend between the longitudinal strips. The glass sheet deviates 0.3 mm or less from planar in the flat sections. The longitudinal strips each have a width W.sub.long of 2 mm or less. The first lateral strips each have a width W.sub.lat of 20 mm or less. At least a portion of the width W.sub.lat of each lateral strip is located in the curved region and a flat section.

Methods and apparatus provide for sourcing a glass web, the glass web having a length and a width transverse to the length; continuously moving the glass web from the source to a destination in a transport direction along the length of the glass web; and cutting the glass web at a cutting zone into at least first and second glass ribbons as the glass web is moved from the source to the destination, the first glass ribbon having a first width and the second glass ribbon having a second width, where the first and second widths are not equal.
