Serial Shift-In Luminance Data (Shift Register Architecture)
Figure 3. Serial Shift-In Luminance Data Structure
This serial shift (shift register) architecture follows a FIFO (first-in first-out) formate.
The MSB (Most Significant Bit), both 8
th
bit and 6
th
bit at the 23rd channel, is the first data
bit that shift into the driver. And the LSB (Least Significant Bit) data, the 1
st
bit at the 1
st
channel, is the last bit in the data sequence. Furthermore, the SELBK control signal is
set to determine in which bank the data are placed.
