Abstract:
PROBLEM TO BE SOLVED: To prevent display flickering and to reduce unwanted radiation noise. SOLUTION: Panel inflow/outflow current during sustained discharge is detected. From the value of inflow/outflow current and the current-voltage characteristic, it is specified that the current-voltage of a display panel is located on the point (b) (V b , I b ). The voltage threshold value Vref is inductively determined from the current threshold value Ir at which the flickering of a screen exceeds the limit. When the voltage value V b is larger than the threshold value Vref, the difference ΔV between both is fed back to a voltage source and the voltage outputting value is lowered in accordance with the difference ΔV. The current-voltage of the panel is returned from the point (b) to the point (a) along the characteristic curve and the current is always suppressed to Ir or less. COPYRIGHT: (C)2004,JPO
