Section 1
Display controller is
combined by the semiconductor read-write
memory, the picture element processor and the demonstration processor. The
read-write processor is the entire display control core. The colored monitor
generally uses RGB (red, green, blue) the tertiary color to control the facture;
it may demonstrate the color type regards the data the figure. If a luminous
spot corresponds three data, can obtain eight kinds of colors; if a luminous
spot corresponds four data, can obtain 16 kinds of colors. When picture element
processor carries on the picture element production in the read-write memory,
the result will be demonstrate on the monitor.
When screen execution demonstration operation, completes the demonstration function by the display control switch, picture element processor is the computer carries on the picture element to live the time intelligent part. When computer execution graphical display the picture element processor explained the computer sends the order and the parameter, realize the painting operation in the read-write memory. It carries out the graph production algorithm, and makes corresponding color data processing.
