The LCD_DUAL_PCK signal is used to latch odd and even pixels into separate latches on the Carrier board, for high
resolution displays, either for parallel LCD implementations or dual channel LVDS. The LCD_DUAL_PCK is derived on
the Module from the LCD_PCK pixel clock. The LCD_DUAL_PCK is one-half the frequency of the LCD_PCK clock. The
Module hardware ensures that the dual pixel clock is phased correctly with the display field. The LCD_DUAL_PCK rising
edge is used to latch odd pixels and the falling edge to latch even pixels. The upper leftmost pixel in the display image
is pixel 1 (an odd pixel), followed by pixel 2 (an even pixel) and so on. LCD_DUAL_PCK is generated using the
module’s CPLD.
