Electro-optic display stacks with segmented electrodes and methods of making the same

A method of manufacturing a segmented electro-optic display, the method comprising:

• providing an electro-optic display stack comprising:
• a first substrate layer;
• a first layer of light-transmissive electrically-conductive material;
• a layer of an electro-optic material;
• a lamination adhesive layer;
• a second layer of light-transmissive electrically-conductive material;
• and
• a second substrate layer;
• forming a plurality of electrically-isolated conductive segments on the second layer of light-transmissive electrically-conductive material using a laser etching process, the laser etching process comprising:
• irradiating the second substrate layer and the second layer of light-transmissive electrically-conductive material at a plurality of locations with a laser emitting light within a first range of wavelengths,
• wherein the second substrate layer is substantially transmissive of light within the first range of wavelengths, and the light-transmissive electrically-conductive material of the second layer of light-transmissive electrically-conductive material is substantially absorptive of light within the first range of wavelengths, and
• wherein, at each of the plurality of locations:
• the second substrate layer substantially transmits the light within the first range of wavelengths, and
• the light-transmissive electrically-conductive material of the second layer of light-transmissive electrically-conductive material substantially absorbs the light within the first range of wavelengths and is removed.
