Abstract

PURPOSE: To ensure an automatic adjustment of the luminance difference in case both the dot display and the linear display are given simultaneously onto the screen by correcting the uneven luminance within the screen, and thus to eliminate the sense of disorder for the displayed picture to increase the reading accuracy of the information.
CONSTITUTION: Data buffer 1 to receive and hold data from CPU is provided, along with pattern generator 2 to convert the data given from buffer 1 into the display character or code plus shift register 3 to convert the converted parallel data output into the series output. Furthermore, main circuit 4 is added to give an automatic correction to the difference of the display luminance via the output of register 3, and the output of circuit 4 is connected to monitor part 6 via interface circuit 6. Then the bit serial data is supplied to circuit 4 from shift register 12, and the waveform detector circuit consisting of FF13 and 15 plus gate 14 and others is provided to detect the dot display vir the clock given from outside. With the output of the waveform detector circuit, transistor 18 generating fixed voltage is controlled to correct the uneven luminance
