Problems solved by technology

Besides adding to the complexity of the overall manufacturing process, the aforementioned sputtering or evaporation processes are not efficient when using metals or metal precursors
Specifically, during vacuum processing, sufficient amounts of metal are deposited on the mask and surrounding structures, rather than on the desired device, whose scrap recycling would be costly and time consuming.

example 1

[0072] Inkjet Silver ConductorAG-IJ-G-100-S1 ink from Cabot Printable Electronics and Displays (Albuquerque, NM) was applied using a JetDrive III driver and MJ-AB-01 40 μm inkjet head obtained from MicroFab Technologies (Plano, TX). Cladding to flat, 1.6 mm thick soda lime glass. Printing parameter settings are typical for inkjet printing. After printing the conductive ink, the isolated samples were cured in a convection oven or drying oven at temperatures of 200, 300, 400 and 500° C. for 20 minutes. The thickness of the cured film was measured using a profilometer (Dektek) and the volume resistivity was calculated.

Abstract

A method for manufacturing electrochromism element comprises: providing a first base plate having a first and second surface and a first edge surface; providing a second base plate having a third and fourth surface and a second edge surface with the third surface facing to the second surface; providing an electrochromism medium, which has a variable light transmittance while applied with a electric field, between the first and the second base plate; coating conductive layer at least a part of one of the surfaces under basic atmospheric pressure applying at least one of metal particulate, organic metal, metallorganics and their combination, in which, the conductive layer has a volume resistivity not less than 150 gemmbo.cm. The conductive layer can be coated by spray painting, ultrasonic spray painting, screw pump spray painting or jet pump spray painting.
