Input panel avoiding interference pattern and method of forming the same
First Claim
1. An input panel of a resistance layer type comprising:
- a first board having a first transparent conductive layer on one surface;
a second board having a second transparent conductive layer on one surface, said first board and said second board being arranged such that said first transparent conductive layer faces said second transparent conductive layer;
first spacers arranged between said first board and said second board, said first spacers being non-conductive and having a height no greater than 14 μ
m; and
second spacers arranged between said first board and said second board among said first spacers, said second spacers being non-conductive and having a height no smaller than 15 μ
m.

Abstract
An input panel of a resistance layer type includes a first board having a first transparent conductive layer on its surface and a second board having a second transparent conductive layer on its surface. The first board and the second board are arranged such that the first transparent conductive layer faces the second transparent conductive layer. The input panel further includes first spacers arranged between the first board and the second board, the first spacers being non-conductive and having a height no greater than 14 μm, and second spacers arranged between the first board and the second board among the first spacers, the second spacers being non-conductive and having a height no smaller than 15 μm.

4. An input panel of a resistance layer type comprising:
-
a first board having a first transparent conductive layer on one surface; a second board having a second transparent conductive layer on one surface, said first board and said second board being arranged such that said first transparent conductive layer faces said second transparent conductive layer; first spacers arranged between said first board and said second board, said first spacers being non-conductive; and second spacers arranged between said first board and said second board among said first spacers, said second spacers being non-conductive and having such a height that no interference pattern is generated, wherein said first spacers have such a height smaller than that of said second spacers that an appropriate input sensitivity of said input panel can be achieved.

5. A method of forming an input panel of a resistance layer type, said method comprising the steps of:
-
a) forming first spacers on a first transparent conductive layer formed on a first board, said first spacers being non-conductive and having a height no greater than 14 μ
m;b) forming second spacers on said first transparent conductive layer, said second spacers being non-conductive and having a height no smaller than 15 μ
m; andc) placing a second board on said second spacers such that a second transparent conductive layer formed on one surface of said second board faces said first transparent conductive layer. - View Dependent Claims (6, 7, 8, 9, 10)
