  • Method for improving fault tolerance of touchscreen and touchscreen terminal
    Patent number: 10712870
    Abstract: A method for improving fault tolerance of a touchscreen determines an abnormal node, and shield the abnormal node to improve the fault tolerance of the touchscreen. The method includes detecting a capacitance value of each node in the touchscreen, comparing the detected capacitance value of each node with a preset capacitance value of each node to determine N target nodes, where N is an integer greater than or equal to zero, and the target nodes are nodes whose capacitance values vary, determining whether an abnormal node is included in the N target nodes, where the abnormal node is a target node determined when no touch operation occurs on the touchscreen, and discarding a row value, a column value, and a capacitance variation value of the abnormal node when the abnormal node is included in the N target nodes.
