Title:
IMAGE DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2006/064688
Kind Code:
A1
Abstract:
An image display apparatus comprises an evacuated envelope having a front board (1) on which a phosphor screen is formed and further having a back board opposed to the front board with a gap therebetween; a metal back including a plurality of divisional parts (M1-M4) overlying the phosphor screen; a plurality of connection resistors electrically connected to the respective divisional parts; a common electrode (30) connected to the metal back disposed around the metal back and electrically connected to the metal back via the connection resistors; a power supply part (50) for supplying charge to the common electrode; and a limiting resistor (60) connected between the common electrode and the power supply part for limiting the charge supply from the power supply part to the common electrode. The structure as described above can prevent any discharge from occurring between the common electrode and the stripe parts, thereby suppressing a long-term discharge, so that the damage which otherwise would occur due to the discharge can be suppressed.
