Abstract
PURPOSE: To simplify and system by carrying out both the display via the coded characters and symbols and the display of the picture element data changed into the dots by means of the dots which are set under each conditions.
CONSTITUTION: Either one of the coded character or symbol information and the dot information to draw an optional pattern is writtern into refresh memory 2 and then read out with the raster timing of CRT synchronous circuit 1. Then the code information of memory 2 is supplied to P/S circuit 8 via pattern generation circuits 8 and 9; while the dot information is supplied directly to P/S circuit 9 and then converted into the data to be displayed on CRT via video control circuit 13. As the code information is capable of recognition of the characters regardless of the shape of the dot, the shape of the dot is set under the band frequency of CRT based on the character and symbol number per line and the number of lines. At the same time, the dot information is set so that the band frequency of CRT as well as the square terms may be satisfied to secure easier viewing. For this purpose, two units of oscillation circuits 5 and 6 are provided to simplify the circuit constitution.
