  • Patent number: 6014123
    Abstract: An extended graphics array (XGA) graphics system is disclosed for converting data received in a double storage bank into a single storage bank when the data is processed. The system includes a graphics data generator for generating synchronizing signals and a main clock signal according to an XGA graphics mode and dividing pixel data to be displayed on a display into even and odd-number data when transmitted from the graphics data generator. It also includes a driving unit having two storage units for storing a predetermined number N of pixel data and for driving the display according to the pixel data stored in the storage units.

  • Patent number: 5828368
    Abstract: A start pulse vertical signal generator using a data enable signal for precharging is disclosed. A clock pulse vertical (CPV) signal generator generates a CPV signal by counting a main clock signal and a data enable signal. A pulse signal generator generates reset pulse signals and delayed pulse signals by using a data enable signal and the CPV signal. A pre-start pulse vertical (STV) signal generator generates an STV signal by using the CPV signal and reset pulse signals and delayed pulse signals. Accordingly, the present invention generates the pre-STV signal two clock pulses of the CPV signal before the data enable signal DE is generated.
