First Claim
1. An electro-tactile panel apparatus for a display panel, said electro-tactile panel comprising:
- a first insulating substrate;
a second conductive layer formed on said first insulating substrate, wherein said second conductive layer is formed of n first electrodes arranged in parallel, and each of said first electrodes has m plates arranged in a line and the edges between the electrodes are connected by a slat to form n×
m plates in total on said second conductive layer, said n and m are nature numbers;
a third insulating layer having an array of n×
m first holes formed therein, wherein said n×
m first holes locate at positions one to one corresponding to said n×
m plates;
a fourth conductive layer formed on said third insulating layer, wherein said fourth conductive layer is composed of m second electrodes arranged in parallel each other and in perpendicular to said first electrodes furthermore, each said second electrode is a slat and has an array of 1×
n second holes formed therein, and hence on fourth conductive layer has n×
m second holes in total corresponding to said n×
m plates;
said fourth conductive layer has n×
m second holes corresponding to said n×
m first holes, wherein said first insulating substrate, said second conductive layer, said third insulating layer, and said fourth conductive layer are made of transparent material;
a holder bound said third insulating layer at an outer plane and said first insulating substrate at inner plane together to said display; and
a controller installed on a sidewall position of said display, wherein said controller receiving display information and electrically coupled with said first electrodes and said second electrodes to provide a skin stimulated current when a person touches said fourth conductive layer thereto connect at least one of said first electrodes and one of said second electrodes simultaneously with his or her skin.

Abstract
An electro-tactile panel (ETP) apparatus for a display panel is disclosed. The ETP apparatus is composed of three major parts: a controller, a panel, and a holder. The panel consists of four layer made of transparent material. The first layer is an insulating substrate, the second layer is a conductive layer formed of a plurality of horizontal electrodes on the first layer. The third layer is an insulating layer having holes formed therein, which corresponding to the electrodes on the second layer. The fourth layer is a conductive layer formed of a plurality of vertical electrodes on the third layer. The panel is attached to the display panel by means of the holder apparatus. The electro-tactile signal and cursor position is process by the controller when the skin touches the panel so that some positions of the vertical electrodes and horizontal electrodes are electrically connected through the holes.
