• Manufacturer Part Number: SSD2119
• Description: 320 Rgb X 240 Tft Lcd Driver Integrated Power Circuit, Source And Gate Driver And Ram
• Manufacturer: Crystalfontz America, Inc.,

B/C: Select the liquid crystal drive waveform VCOM.
EOR: When B/C = 1 and EOR = 1, the odd/even frame-select signals and the N-line inversion signals are EORed for
alternating drive. EOR is used when the LCD is not alternated by combining the set values of the lines of the LCD driven
and the N-lines.
NW[7:0]: Specify the number of lines that will alternate at the N-line inversion setting (B/C = 1). N-line is equal to
NW[7:0]+1.

When B/C = 0, frame inversion of the LCD driving signal is enabled.
When B/C = 1, a N-line inversion waveform is generated and alternates in a N-line equals to NW[7:0]+1.
