Lithium containing glass or glass ceramic article with modified k2o profile near the glass surface

A consumer electronic device comprising:

• a housing;
• electrical components provided at least partially internal to the housing, the electrical components including at least a controller, a memory, and a display, the display being provided at or adjacent to a front surface of the housing;
• and
• a cover article disposed at or over the front surface of the housing and over the display, wherein the housing or cover article comprises the alkali aluminosilicate glass article of claim 15.

An alkali aluminosilicate glass article comprising:

• Li2O, Na2O, and K2O;
• a compressive stress layer extending from a surface of the alkali aluminosilicate glass to a depth of compression (DOC);
• a tensile region extending from the depth of layer into the glass article and having a maximum tensile stress of at least about 40 MPa;
• and
• a K2O concentration at a depth of about 15 μm to about 25 μm that is at least about 0.3 mol % higher than a K2O concentration at a center of the alkali aluminosilicate glass article.
