COMPUTER SYSTEM WITH DUAL-PANEL LCD DISPLAY |
摘要 |
A computer system includes a dual-panel monochrome or color liquid crystal display (LCD). A dynamic random access memory (DRAM) of the computer includes a defined virtual memory array representative of pixel locations of the dual-panel LCD. Pixel values are read from the virtual array of the DRAM and written to corresponding locations of the display by a display pipeline. The writing of pixel values to the display proceeds pixel-by-pixel across a row of pixels in a panel, and then to the next row of pixels until a panel is refreshed. The panels of the array are refreshed one at a time alternating between an upper panel of the display and a lower panel of the display. While one panel is being refreshed, the other panel is blanked. Consequently, the dual-panel display may be driven with a simplied structure of display pipeline, and with a reduced time requirement for access to the DRAM.
