Abstract
A method for configuring button keys on a membrane includes the steps of: mapping the membrane under the conditions of without jumping and without generating ghost keys; gathering adjacent button keys on a same cluster; defining a button key configuration chart according to each cluster; and linking circuits of each button key in each cluster to a flat cable of the membrane. Then defining total number of various composite keys; locating the composite keys to be not co-linear or cross co-linear on the X-axis or the Y-axis of the matrix scanning lines; and mapping other adjacent button keys without the jumping.
Claims3
A method for configuring button keys on a membrane for producing the membrane without wire jumping, comprising the steps of:
- a. gathering adjacent button keys as a same cluster;
- b. defining a button key configuration chart according to each cluster;
- and
- c. linking circuits of each button key in the same cluster to a flat cable of the membrane.
A method for configuring button keys on a membrane for producing the membrane without generating any ghost key signal output, comprising the steps of:
- a. defining total number of composite keys;
- b. locating the composite keys to be not co-linear or cross co-linear on the X-axis or the Y-axis of matrix scanning lines;
- and
- c. mapping other adjacent button keys without wire jumping.
