Abstract: A data programming method includes the following operations: assigning a first identity code to initial data according to a data type of the initial data; packing the first identity code, the initial data, and a check code to a new data packet; determining whether a first storage space in a flash memory stores a first data packet being the same as the new data packet; and if the first storage space does not store the first data packet, programming the new data packet to the first storage space in a first address sequence.

Abstract: A self-capacitive touch panel including two sensing regions is provided. Each of the sensing regions includes a first sensing channel, a second sensing channel, a border electrode and multiple central electrodes. The border electrode utilizes the first sensing channel exclusively. The central electrodes share the second sensing channel. The border electrode has a first centroid, which represents a position where a capacitance change contributed by the border electrode occurs. The central electrodes have a second centroid, which represents a position where a capacitance change contributed by the central electrode occurs. An average distance from the first centroid to all possible touch points in the border electrodes is shorter than an average distance from the second centroid to all possible touch points in the central electrodes.
