摘要：
A cover element for an electronic device that includes a redrawn glass element, first and second primary surfaces, and a polymeric layer disposed over the first primary surface. The redrawn glass element has a reduced thickness and an average surface roughness of 1 nanometer or less. Further, the cover element can withstand a pen drop height of greater than 6 centimeters or 2.5 times or more than that of a control pen drop height of the cover element having a non-redrawn glass element the layer according to Drop Test 1.
