PROCESS AND MATERIALS FOR IMAGEWISE PLACEMENT OF UNIFORM SPACERS ON FLAT PANEL DISPLAYS.

摘要

PURPOSE: A method and materials for placement of structurally supporting spacers on a receptor using a thermal transfer doner sheet and imaging radiation is employed to accurately place uniform spacers in designated locations outside the display windows. CONSTITUTION: A receptor is placed in intimate contact with the transferable spacer layer of the thermal transfer donor sheet. At least one of the thermal transfer donor sheet or the receptor is radiated in an image wise pattern with imaging radiation such that the radiation absorber in either the receptor or thermal transfer donor sheet construction absorbs a portion of the imaging radiation and converts that radiation to heat. The transferable spacer layer in the irradiated areas is transfered to the receptor, and the thermal transfer donor sheet is removed to form spacer elements corresponding to the irradiated areas on the receptor.
