Abstract:
1. A process for producing a color electrophoretic display including first and second color filter materials on a backplane of the color display, comprising: providing an opaque backplane comprising first and second sets of electrodes; depositing on the backplane a coating of a material having a surface characteristic capable of being modified by radiation; applying radiation to a first area of the coating aligned with the first set of electrodes but not to a second area of the coating, said second area of the coating being aligned with said second set of electrodes; depositing a flowable form of a first color filter material on to the first area of the coating; converting the flowable form of the first color filter material on the first area of the coating to a non-flowable form; applying radiation to the second area of the coating; depositing a second color filter material on to the second area of the coating; and laminating an electrophoretic medium and a front electrode to the backplane, thereby producing a color electrophoretic display.
