Fig. 1 is the upper schematic diagram of the contact panel of first embodiment of the invention.Please refer to Fig. 1, the contact panel 100a of the present embodiment is such as connected to p signaling channel of chip by connection pad 200, wherein p is positive integer, and p is such as 14.That is, the numeral in Fig. 1, each connection pad 200 indicated is the sequence number of signaling channel that connects of connection pad 200 for this reason.Contact panel 100a comprises substrate 110, multiple electrode pair 120 and multiple Communication signal wire 130.
Electrode pair 120 is configured on 110 substrates.These electrode pairs 120 are arranged in the layout (layout) of matrix, and electrode pair 120 is arranged in the matrix that q hurdle r arranges.Q, r are respectively positive integer.In the present embodiment, q is 9 and r is 5, and namely, the contact panel 100a of the present embodiment is that the matrix arranged electrode pair 120 to be arranged in 9 hurdles 5 illustrates.Certainly, the present invention is not limited thereto.
In other embodiments, electrode pair 120 also can be arranged in the matrix of different column number and different columns.Should be noted that, represent the position of jth hurdle kth row in Fig. 1 with label (j, k), j is such as the positive integer of 1 ~ q, and k is such as the positive integer of 1 ~ r.For example, number in the figure (1,1) represents that the position that the 1st hurdle the 1st arranges, number in the figure (5,1) represent the position that the 5th hurdle the 1st arranges ... Deng.In the present embodiment, j may be 1 ~ 9 and k may be 1 ~ 5.
Electrode pair 120 comprises the first electrode 122 and the second electrode 124.First electrode 122 is connected to the h signaling channel of chip by the connection pad 200 of correspondence, and the second electrode 124 is connected to the i-th signaling channel of chip by the connection pad 200 of correspondence.H signaling channel and i-th signaling channel of chip form signaling channel pair, and wherein h is not equal to i, and h, i are 1 ~ p.In other words, the first electrode 122 and second electrode 124 of same electrode pair 120 can be connected to two different signaling channel respectively, and these two signaling channel form a signaling channel pair.
Should be noted that, the number in Fig. 1, the first electrode 122 and the second electrode 124 indicated represents the sequence number of the signaling channel that this electrode connects.In other words, if indicate 2 in the first electrode 122, namely represent that this first electrode 122 is connected to the 2nd signaling channel.In the present embodiment, signaling channel has 14, and such as, so h with i, is the positive integer of 1 ~ 14, in other words, chip such as, is include the 1st signaling channel to 14 kinds of the 14th signaling channel different signaling channel.
In addition, the signaling channel that the electrode pair 120 that jth hurdle kth arranges connects is to any one signaling channel pair connected be different from other electrode pair 120.For example, the signaling channel that connects of electrode pair 120 that arranges of the 1st hurdle the 3rd is to being that the 4th signaling channel that the 2nd signaling channel that connected by the first electrode 122 and the second electrode 124 connect is formed.The signaling channel that connects of electrode pair 120 that 5th hurdle the 1st arranges is to being that the 6th signaling channel that the 1st signaling channel that connected by the first electrode 122 and the second electrode 124 connect is formed.The signaling channel that the electrode pair 120 that 6th hurdle the 4th arranges connects is to being the 7th signaling channel connected by the first electrode 122 and forming the 10th signaling channel connected by the second electrode 124.
