摘要： The invention discloses a liquid crystal screen glass cutting method and apparatus to solve the unhealthy problem of being broken or serrated to be produced for the liquid crystal screen glass at intersections of cutting marks in different directions in the cutting procedure. This liquid crystal screen glass cutting method comprises: a cutter wheel cutting a first surface of the liquid crystal screen glass along a first direction for the first time to form first cutting marks on the liquid crystal screen glass; and after the completion of the first-time cutting, the cutter wheel cutting the first surface of the liquid crystal screen glass along a second direction for the second time, wherein when the distance from a first cutting mark equals a cutter-out distance, the cutter wheel rises a jump height perpendicularly to the liquid crystal screen glass and keeping the jump height, travels a stroke along the second direction which is a sum of the cutter-out distance and a cutter-in distance, then descends perpendicularly to the liquid crystal screen glass to the liquid crystal screen glass and continues to cut the liquid crystal screen glass along the second direction, until second cutting marks are formed on the first surface, wherein the second direction is perpendicular to the first direction.
