Provided are a method and apparatus for drying and cooling a glass substrate, comprising the steps: moving a glass substrate, which has been cleaned by way of a cleaning apparatus, into a drying chamber by means of a first roller apparatus (S10); drying the glass substrate by means of an infrared heating plate arranged in the drying chamber (S11); moving the dried glass substrate into a cooling chamber by means of a second roller apparatus (S12); cooling the dried glass substrate by means of a cooling plate arranged in the cooling chamber (S13); transferring the cooled glass substrate to a pre-coating platform of an air-flotation coating machine to coat the glass substrate (S14). Also provided is a corresponding apparatus. The invention reduces the amount of foreign particulate matter before a glass substrate is coated, and the drying is effective.
