  • Patent number: 5395414
    Abstract: A novel display panel (10) has a high fidelity visual pattern with a full range of grey scale values, for instance, a marble or leather pattern, which is produced via a novel methodology (20). In accordance with the novel methodology (20), a high resolution visual pattern (31) and a mask pattern (32) are produced and separately printed. The patterns (31, 32) are then superimposed and exposed to a camera (33) which generates an enlarged photograph positive. A silk screen is produced from the enlarged photograph positive and used to print a high fidelity visual pattern onto a glass substrate (13). The glass substrate (13) and visual pattern (14) are then heated in a tempering oven to derive the display panel (10).
