A method of manufacturing a display device includes: providing a glass including an edge region and an inner region; arranging a light source under the glass; setting a center position of the light source to correspond to an inside of the edge region or an inside of the inner region of the glass; directing light into the glass by using the light source; and detecting a defect in the edge region of the glass by receiving light passing through the glass by using a detection camera.

A process for producing a surface covering with an embossed printed surface is described. A substrate (16) is continuously moved through a production line, and this substrate (16) is first provided, in a printing equipment (12), with a printed pattern and thereafter, in an embossing equipment (14), with an embossed pattern, which is registered with the printed pattern. The printing equipment (12) produces the printed pattern in-line with the production of the embossed pattern. During printing in the printing equipment (12), the printed pattern is stretched or compressed, dynamically responsive to indicators of misalignments between the printed pattern and the embossed pattern, so as to correct or prevent the misalignments. A production line for carrying out this process is also proposed.

A method to utilize the results from a series of FEM models to develop a master derivative of compliance curve. The use of the unique master curve resolves the test data variability issue caused by fitting the compliance curve individually. The analytically derived derivative of compliance curve eliminates the needs to take the derivative of compliance and therefore the derivative computation error no longer exists. By applying the existing solution and the solution as disclosed and claimed herein to the same set of the raw test data, it is found that data scatter is significantly reduced.
