Abstract

In fabrication of plasma display panels, an array of conductor lines is provided on each glass plate by conventional photolithographic techniques. However, panel conductor lines prepared on glass plates without the use of photolithographic techniques are especially advantageous for high resolution panels using a conventional electrode array design, i.e., no fan in or fan out at the ends of the arrays. After metallized layers of chrome-copper-chrome are formed on the plates, the conductor lines are gang sawed into the metallized plates. Diamond saws of appropriate width and spacing can be set to cut the Cr-Cu-Cr metal to minimum depth into the glass plates. Numerically controlled stepping could be used for inter-digitizing the lines. The plates would be washed and dried after conductor line cutting.

Improved Method for Fabricating Plasma Panel Conductor Lines

In fabrication of plasma display panels, an array of conductor lines is provided on each glass plate by conventional photolithographic techniques. However, panel conductor lines prepared on glass plates without the use of photolithographic techniques are especially advantageous for high resolution panels using a conventional electrode array design, i.e., no fan in or fan out at the ends of the arrays. After metallized layers of chrome-copper-chrome are formed on the plates, the conductor lines are gang sawed into the metallized plates. Diamond saws of appropriate width and spacing can be set to cut the Cr- Cu-Cr metal to minimum depth into the glass plates. Numerically controlled stepping could be used for inter-digitizing the lines. The plates would be washed and dried after conductor line cutting. An added advantage of this technique is that the ground glass where the conductor element had been sawed would inhibit specular reflection.
