ABSTRACT:
A system, a circuit and a method are given, to realize a display control and driver interface with graphic display memory, whereby the use of dynamic RAM rather than static RAM for this graphic display memory is new. This has the advantage, that for a given size of display memory (number of bits) the DRAM silicon area is significantly less than that of the SRAM. Said system and circuit are designed in order to be implemented with a very economic number of components, capable to be realized with modern monolithic integrated circuit technologies and implementing the given method. This display controller and driver chip can then be used for all LCD display devices including STN (Super Twisted Nematic), CSTN (Colour STN), TFT (Thin Film Transistor) LCD's and for OLED (Organic Light Emitting Diode) displays.
