Japanese Patent JPS6090617
Kind Code:
U
Abstract:
A cold cathode discharge tube is disposed as a light source on the front side of a display unit, and a grounded connector is disposed on and/or in the neighborhood of the outer periphery of the cold cathode discharge tube. The conductor causes electric noise generated from the cold cathode discharge tube to flow to the ground, thus preventing the rupture and erroneous operations of the liquid crystal display unit accommodating driving ICs.
