Formation Of Various Coating Films On Cathode Ray Tubes And Lamps
(AREA)
Abstract
FIELD: electronics. SUBSTANCE: light guide has wedge-shaped section 1 with convergent flat side edges 2 which form output rectangular face 3, and cylindrical section 4 with end face. The latter has recess 5 or projection formed by cylindrical surfaces 7, 8 so that their intersection line is perpendicular to light guide axis, to longitudinal edges of its output face 3. EFFECT: higher uniformity of screen illumination; higher quality of screen. 6 dwg
