Stella has developed calculation software of sheet resistance of electrode automatically as a design tool of electrode pattern. Once-time, shape of electrode is limited to stripe line, but it could support all shapes of electrode by new algorithm. This is world first, as a result, it is possible to apply PM-LCD, PM-OLED, design assist tool of FPC, and so on. We released this software as optional software of Stella Vision for Java.
In this software, first of all, you design electrode pattern by PC. Subsequently, you input sheet resistance correspond to electrode material and its thickness. And then, you indicate measurement area by mouse click. As a result, you can see sheet resistance for 10 sec(picture 1).
As above, shape of electrode is limited to stripe line, but it could support all shapes of electrode involved curved line by new algorithm. In this software, it's possible to change electrode design, such as bending shape and etching by manual operation. In this case, it's possible to changed calculate sheet resistance at once.

| We upgraded these functions; as a result, we succeeded to develop new automatic adjustment function of sheet resistance. This function makes it possible to uniform sheet resistance of all electrode lines based on above calculation. In concretely, it uniforms sheet resistance by arrangement of width of electrode line while keeping space between line and line. In this time, it can uniform sheet resistance because by arrange width of electrode in one block area while keeping width of electrode in another block area. In short, it is possible to keep design which is almost same one at physical appearance. In this case, if the data is simple, it is enough time to complete for less than 30 sec. |
