Title: Multicolor display device
Inventor: NAKAJIMA KENICHI
IPC: G09G5/06
Filed: 1995-05-26
Abstract: PURPOSE: To provide a display device which, at the time of generation of setting change processing and setting readout, compeltes the operation in spite of display period and non-display period by displaying the display data one pixel before. CONSTITUTION: When a command 31 of setting change processing and setting readout is generated, a pulse generator circuit 70 produces pulses for one period of the display clock. A selector 10 selects the address inputting signal 32 of setting change processing and setting readout by the pulses of one display clock width. Accordingly memory (pallet register) 20 storing pallet data outputs the data of setting change processing and setting readout to a system bus 30 and a flip-flop 50. On the other hand, using the pulses generated at a pulse generator circuit 70, a clock control circuit 60 suspends the display clock for the flip-flop 50 for one clock. Accordingly the flip-flop 50 remains to hold the hue data by one display clock before.
