Abstract:
1. A method for magnifying and displaying a local image displayed on a touch display device, the touch display device comprising a display panel and a touch panel integrated on the display panel, the touch panel having a touch surface defining an effective touch zone, comprising the following steps: (a) detecting if an approaching object is approaching the touch surface in the effective touch zone; (b) detecting an approaching object position in the effective touch zone of the touch panel where the approaching object heads for, the approaching object position being associated with at least one target graphic representation displayed on the display panel; (c) determining an approaching altitude of the approaching object on the approaching object position in the effective touch zone of the touch panel with respect to the touch surface of the touch panel; (d) magnifying and displaying the target graphic representation associated with the approaching object position based on a first predefined magnification and a predefined image magnification mode setting in relation with a first predefined approaching altitude value when the approaching altitude of the approaching object with respect to the touch surface of the touch panel is detected to be less than the first predefined approaching altitude value; and (e) detecting and determining if the approaching altitude of the approaching object with respect to the touch surface of the touch panel is less than a second predefined approaching altitude value, wherein the second predefined approaching altitude value is less than the first predefined approaching altitude value but greater than zero; (f) determining if the target graphic representation associated with the approaching object position is an executable object; and (g) executing the executable object of the target graphic representation when the approaching altitude of the approaching object with respect to the touch surface of the touch panel is less than the second predefined approaching altitude value and before the approaching object is in contact with the touch surface of the touch panel.
