Application No. 08/922,300
11. A display device with a power interruption delay
function, comprising:
a pulse width modulation controller for generating a pulse
width modulation signal under the control of a microcomputer;
a current amplifier for amplifying current in response to
the pulse width modulation signal from said pulse width
modulation controller;
a horizontal/vertical processor for generating a square wave
pulse signal under the control of said microcomputer;
a horizontal driver for generating a drive pulse signal in
response to the square wave pulse signal from said
horizontal/vertical processor;
a horizontal deflection coil for horizontally deflecting
electron beams generated in said display device;
a S-correction capacitor connected in series between said
horizontal deflection coil and a ground terminal, for correcting
a linearity of center-to-left and right sides of a screen;
a horizontal output circuit for charging and discharging
energy on said horizontal deflection coil and said S-correction
capacitor in response to an output signal from said current
amplifier and said drive pulse signal from said horizontal
driver;
a horizontal/vertical processor constant voltage circuit for
supplying a constant voltage to said horizontal/vertical
processor in response to an input voltage; and
power interruption delay charging means for gradually
lowering said input voltage to said horizontal/vertical processor
constant voltage circuit when power supplied to said display
device is interrupted.
