Description
132~140,142~150, D05 ~ D00
Data input. For three 6-bit data,1 pixel, of color data (R, G, B)
112~120,122~130, D15 ~ D10 I DX5 : MSB; DX0 : LSB
47~55, 57~65 D25 ~ D20
31 ~ 34
REV
I Controls whether data is inverted or not.
When “REV”=1 the data will be inverted. EX. “00” “ 3F”, “07” “ 38”, “15” “2A”,
and so on.
152 ~ 155
CLK
I Clock signal; latching data onto the line latches at the rising edge.
69 ~ 71
SELT
I Selects the output channel number; when SELT= “0” : 309 channels; and “1” = 300
channels (OUT151~ OUT159 are in-available ). There is a 100K internal pull-up
resistor with this pin.
106 ~ 77
V1 ~ V10
I Gamma correction reference voltage. The voltage of these pins must be AVSS<
V10< V9< V8<V7<V6; V5<V4<V3<V2<V1< AVDD
189 ~ 497
OUT1 ~
OUT309
O Output drive signals;
If 300-channel function is selected, OUT151~ OUT159 are in-available.
35 ~ 37
SHL
I Selects left or right shift;
SHL=“1” : DIO1 OUT1,2,3 OUT4,5,6 OUT7,8,9--- OUT307,308,309= DIO2
SHL=“0” : DIO1=OUT1,2,3 OUT4,5,6 OUT7,8,9 --- OUT307,308,309 DIO2

DIO1 I/O Start pulse signal input/output
8 ~ 10
DIO2
When SHL is applied high (SHL="1"), a start high-pulse on DIO1 is latched at the
rising edge of the CLK. Then the data are latched serially onto internal latches at
the rising edge of the CLK. After all line latches are full with data, 100/103 clocks, a
pulse is shifted out through the DIO2 pin at the rising edge of the CLK. This function
can cascade two or more devices for dot expansion. In normal applications, the
DIO2 signal of the first device is connected to the DIO1 of the second stage, and the
DIO2 of the second one is connected to the DIO1 of the third, and so on like a daisy
chain.
In contrast, when SHL is applied low, a start pulse inputs on DIO2, and outputs
through DIO1.
*Remark : The input pulse-width of DIO1/2 may be over 1 clock-cycle.
44 ~ 46
LD
I Latches the polarity of outputs and switches the new data to outputs.
1. At the rising edge, latches the “POL” signal to control the polarity of the outputs.
2. The pin also controls the switch of the line registers that switches the new
incoming data
to outputs.
*Remark : The LD may switch the new data to outputs at anytime even if the line
data are not completely full.
