SCREEN FOR A ELECTRONIC WHITEBOARD AND MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: A screen for an electronic whiteboard and a method thereof are provided to prevent the light source of a projector from being projected on the screen when the screen is used for projecting an image, thereby offering a uniform image quality and a wide viewing angle. CONSTITUTION: A method of a screen for an electronic whiteboard comprises a first process(S10) for forming a finely uneven surface on the one surface of tempered glass by spraying a fine injecting material with a high pressure air; and a second process(S20) for painting and hardening the surface of tempered glass on which the surface processing is completed in the first process. The file injecting material in the first process is steel balls. The second process includes the steps of: silkscreen-printing hyaline ink and painting the surface of the tempered glass(S21); and first-hardening the tempered glass in a drying furnace at 100 to 140°C and second-hardening the same in a hardening furnace at 700 to 800°C(S23).
