Definitions

  • the present disclosure relates to a glass composition and a cover glass.
  • the present disclosure relates to a glass composition and a cover glass, wherein the cover glass is scratch resistant and is featured with high silica content, reduced density, reduced brittleness and high strength.
  • Devices such as the mobiles or cell-phones, palm top computers, watches, laptops, portable gaming devices with displays, notebooks, televisions, displays in vehicles, touch panels screens and other electronic devices, etc., have become ubiquitous in devices, wherein at least a glass cover plate is included to protect the device (particularly the display part therein).
  • the cover plate is generally transparent to allow the user to view a display.
  • the glass cover plates used in such devices are prone to breaking and/or damage due to various reasons such as accidental dropping, improper cleaning and also as the usage of the device increases. It is desirable to have cover glasses designed to survive the high levels of ill-treatment or accidental dropping that may occur due to contact or impact of the cover glasses with sharp objects.
  • the glass cover plates must also exhibit high strength and at the same time must be scratch resistant if the device with the cover glass is frequently contacted or touched such as in a touch screen display.
  • the glass covers are manufactured by one of the sheet glass manufacturing processes, namely, the float glass process, the down-draw fusion process, slot draw process, press-formable (molding) process, roller press process and the like.
  • the down-draw fusion process [also known as the down-draw process] is capable of producing a precision fire-polished surface that requires no additional modification such as grinding or polishing prior to use.
  • the specifications of US patents 3,338,696 and 3,682,609 disclose fusion downdraw processes which include allowing flow of molten glass over the edges or weirs of a forming wedge, referred to as isopipe. The molten glass flows over converging forming surfaces of the isopipe and the separate flows reunite at the apex or root where the two converging forming surfaces meet to form a glass sheet.
  • the glass which has been in contact with the forming surfaces is located in the inner portion of the glass sheet and the exterior surfaces of the glass sheet are contact free.
  • Pulling rolls positioned downstream of isopipe root capture edge portions of the glass sheet so formed to control the rate at which the glass sheet leaves the isopipe and thus aids in controlling the thickness of the finished sheet.
  • the glass sheet descends from the root of the isopipe past the pulling rolls, it cools to form a solid elastic glass sheet, which may be processed further.
  • One such material property is the viscosity of the glass. It is desired to maintain the viscosity of the glass at the location where it leaves the isopipe at a value greater than about 10 5 poise, which if not maintained the glass sheet flatness and thickness across its width becomes difficult to control, which may result in a glass sheet being not suitable for display applications.
  • liquidus viscosity of the glass substrate Another significant factor is liquidus viscosity of the glass substrate. It is desired to have lower liquidus temperatures and hence higher liquidus viscosities for the down draw process or any other manufacturing process. The lower liquidus temperature and higher liquidus viscosity result in the glass being resistant to crystallization during the forming process. Since the forming is started at glass viscosities from about 10 4 to about 10 5 poise, it is desired that the glass exhibits a liquidus viscosity of greater than about 10 5 poise.
  • the substrate glass is desired to exhibit high durability to chemical treatments during the TFT manufacturing and long term exposure to environmental conditions in service.
  • cover glass is to be used in portable devices such as laptops, clocks, mobiles, which are light-weight devices.
  • the substrate glass which forms an important part should also have a relative low weight, which in-turn implies that the substrate glass itself should be light weight.
  • light weight means that the thickness of the glass is less, and for portable device applications the thickness is less than about 1.1 mm, preferably less than about 0.7 mm and most preferably less than about 0.5 mm. It should be possible to manufacture glasses with the desired thickness and it is also desirable to have glass composition that are suitable for manufacture of such glasses, wherein the glasses may be melt drawn into thin sheets of desired thickness.
  • the substrate glass should exhibit a low coefficient of thermal expansion (CTE), typically, in the range of from about 72 x 10 "7 /°C to about 76 x 10 "7 /°C to be compatible with processes for Soda Lime glass which has a CTE close to 80 x 10 "7 /°C.
  • CTE coefficient of thermal expansion
  • screens or glasses that are used for touch sensitive screens of electronic devices are typically chemically-strengthened by the ion-exchange method.
  • the ion chemical strengthened ion-exchanging of the glasses provides extra strength to the glasses.
  • the ion exchange step is carried out after the glass sheets are formed by chemically treating the heated glass sheets with a heated solution of ions having larger ionic radius than ions that are present in the glass surface, thereby replacing the smaller ions with larger ions.
  • the smaller ions are those of sodium and are replaced with larger ions such as those of potassium.
  • glasses such as "the soda lime” glasses are compatible with large-scale sheet glass manufacturing via float process but cannot be formed by methods particularly the down-draw process as the viscosities of the soda glasses are too low owing to their high liquidus temperatures. It is desired to have glasses that could be formed using any of the above mentioned processes for forming the glass sheets.
  • the density of commercial soda lime glass is close to 2.5 g/cc, which makes the glass heavier for the application of the cover glass for displays.
