1. A method for removing defects from a glass article of a mobile device electronic display, comprising:
positioning a mobile device electronic display comprising a glass article relative to a laser emitting a fan-shaped infrared beam;
irradiating the glass article of the mobile device electronic display by the laser;
cycling the laser between on and off in order to control heat generation and penetration to prevent damage to the electronic display; and
moving the glass article and the laser relative to each other to melt and anneal a portion of the glass article irradiated by the laser.
