should be given to the following points when using the CXD2411AR.
1) During CSYNC input, the XVD input pin should be set to L or left open.
2) During Separate SYNC input (XHD, XVD), the XVD width specification is from 2H to 10H.

SLFR is the selector switch for the AC drive timing pulse (FRP). This switch selects field inversion when H and
line inversion when L. Normally, line inversion (L) is used. The transition point is one clock cycle after the
transition point of the VCK1 and VCK2 pulses.

These are selector switches for the horizontal display position. The HST timing can be set at 2fh intervals in 16
different ways by using the four HST position bits. The picture center is set at internal preset value: HP1/2/3/4:
LLLH. However, actually, because there is a difference between the RGB signal and the drive pulse delays,
the picture center may not match the design center. In this case, adjust with these switches.
The HST timing (from SYNC termination to the rising edge of HST) for even lines is shown below.

CXD2411AR
Right/Left Inversion
The LCD panel is arranged in a delta pattern, where identical signal line has 1.5-dot offset at adjoining vertical
lines. For this reason, a 1.5-bit offset is attached to the horizontal start pulse (HST) between odd lines and
even lines. HCK and SH are also 1.5-bit offset in a similar manner.
When the panel is driven with left scan (Reverse scan), this offset relationship becomes inverted for even and
odd lines. Moreover, since the dot arrangement is asymmetrical, the HST position is also changed. The
CXD2411AR deals with this inversion as follows.
When using single-panel
(1) When the right/left inversed-identification pin (RGT) goes L, the relationship concerning HCK output
switches between odd and even lines. In this case, use HST1 for the horizontal direction start pulse.
When RGT is H:
Right scan mode is on. The right scan drive pulse is output by the timing generator and is supplied to
the panel.
When RGT is L:
Left scan mode is on. The left scan drive pulse is output by the timing generator and is supplied to the
panel.
When using three-panels
(1) In order to be able to simultaneously drive three panels, with a mixture of right/left inversion on and off,
output two pulses regarding HST pulse: HST1 for right scan (Normal scan) and HST2 for left scan
(Reverse scan).
In addition, left and right scan outputs are necessary for the RGT signal as well. However, since this timing
generator does not have an RGT (right/left inversed-identification) output pin for left scan, external
measures must be taken. Similarly, external measures are also taken for HCK1 and 2.
Regarding SH, the wiring of SH1 and SH4 to the driver IC.
(2) When the right/left inversed-identification pin (RGT) goes L, the relationship concerning HCK output
switches between odd and even lines for each output switches.
When RGT is H:
Right scan mode is on. The right scan (A) and left scan (B) drive pulses are output by the timing
generator and are supplied to panels 1 and 2 and panel 3, respectively.
When RGT is L:
Left scan mode is on and (A) and (B) outputs are switched. Accordingly, panels 1 and 2 are used for
left scan and panel 3 changes to right scan.
