16-Channel PWM-Controlled Constant Current Driver
for LED Displays
General Description
The DM132 is a LED driver incorporating shift registers, data latches, 16-channel
constant current circuitry with current value set by an external resistor, 1024 gray level
PWM (Pulse Width Modulation) functional unit and time division capability. Each channel
can provide a maximum current of 60 mA. Time division operation allows driving up to 1 or
2 LEDs with a single output channel (mode-1 and mode-2 respectively).

Typical Control Method
1) Command Sequence
To manipulate DM132, we should properly control the CMD, DIN, DCLK, and GCLK as
following steps:
1. Issue command “Shift-in”, and then enter luminance data DIN. Note that DM132
starts to shift-in data at the DCLK rising edge next to the edge which latched
Shift-in command.
2. After data are completely entered, send command “Capture” to save data in
registers.
3. Issue command “Emitting” or ”Disable”. Note that:
A. DM132 generates its output in one-shot fashion, i.e. the output after (1024) x
TGCLK is always zero.
B.
There are 3 GCLK latencies between the latched LED Emitting/Disable
command and PWM start/stop. This is shown in Figure 2.
4. Repeat step 1~4. In the same frame, the luminance data doesn’t have to be
changed, just repeat step 3~4. Note that the second command “Emitting” will be
omitted if the last (1024) x TGCLK PWM has not finished, unless the “Disable”
command is sent in advance.
The process discussed above could be summarized in the following table. At the
same time, DCLK and GCLK remain free running.

2) LED Emitting Time and Current
DM132 adjusts the LED luminance using PWM (pulse width modulation) technique.
The luminance data (DV) has a resolution of 10 bits (1024steps) and can be set
independently for each LED. The relationship between Iout, luminance data, and emitting
time is shown in Figure 2.

Detailed Description
1) Time Division Operation
Since each DM132 output could drive 1 LED or 2 LEDs, the users can choose
either MODE1 luminance data or MODE2 luminance data. After the luminance data is
given, a command should be issued so that the driver can operate in MODE1 or in
MODE2. Figure 3 shows the route of data shift-in in MODE2. Later we will explain the
data structure of MODE1 and MODE2 in more details.

Figure 4 shows how to switch between 2 LEDs. When “LED1 Emitting” command
is sent, LED1 PWM output will start 3 GCLK later. At the same time, the switch of
LED1 should be turned on. On the other hand, LED2 switch should be turned on when
LED2 PWM output starts. Again, “Disable” command must be sent before
“LED1/LED2 Emitting”. By periodically switching the emitting commands and LED
switches, we could drive 2 LEDs per channel.

2) Serial Shift-In Luminance Data
In the MODE1 operation, the data for shift registers and latches is set as
{16(channel) x 10 bit (luminance) x 1(led)} whereas in MODE2 operation, the data is
set as {16(channel) x 10 bit (luminance) x 2(led)} configuration. The driver IC can
remember both 2 sets of luminance data.
The serial shift architecture assumes a FIFO (first-in firs-out) discipline, hence in
the MODE1 operation, the most significant bit (MSB, Bit 9, Channel 15) luminance
data is the first data shifted in, whereas the least significant bit (LSB, Bit 0, Channel 0)
is the last data bit in a data set. The data structure for the MODE1 and MODE2 is
shown in the Figure 5 and Figure 6 respectively.

3) Driver Current Output
The drive current is set by an external resistor, Rext, connected between the
REXT pin and GND. Varying the resistor value could adjust the current scale ranging
from 5mA to the maximum 60 mA. Note that the REXT pin voltage is designed to be
independent of supply voltage, temperature, and process variation, and is
approximately 1.228V.
The output current could be calculated roughly by the following equation:
Iout = (1.228 / Rext) x 48
The full-scale current IOUT vs. Rext is shown in Figure 7.

6) Advantages for application
To understand what the advantages over ON-OFF type drivers, we assume that
in MODE 1 operation, the frame rate is 60Hz, DCLK & GCLK both run at 10MHz. We
can shift in (1/60Hz)/(1/10MHz)=167K bits per frame. One channel takes 10 bits, thus
167K/10=16.7K channels (single color pixels). For two dimension display, we take the
square root of 16.7K pixels, which equals 129. The resolution, in this case is 129*129.
We can round the data a little bit, and we can construct a 128*128 image by
DM132
Version:A.014
Page: 17
點晶科技股份有限公司
DM132
SILICON TOUCH TECHNOLOGY INC.
connecting 1024 driver ICs. (1,024 EA drivers*16 channels≒16,384 bit).
Within a frame, there are 1024*16*10=163K DCLK & GCLK cycles, and we know
that the PWM takes 1024 GCLK cycles and is one-shot. So we can issue up to
163K/1024=160 PWM cycles within a frame. This can be used as an 160-level total
brightness control in addition to the 1024-level pixel-dependent luminance control.
These 160- “LED1 Emitting” shall be issued periodically within a frame. Each time
when issuing the “LED1 Emitting” command, the shift-in process will be pended for a
few cycles; however, we can resume feeding the data right after the “LED1 Emitting”
command is issued.
To make the total brightness at full scale, all 160 “LED1 Emitting” commands
should be issued. To make the total brightness half of the full scale, we can issue
80-“LED1 Emitting” commands in companion with 80-“LED Disable” commands, so
that all the 128*128 LEDs are half of their brightness.
A comparison table for PWM LED driver vs. ON-OFF type is provided for
reference.

Surely out of spec. Can’t realize in this configuration. System designs for ON-OFF type drivers thus need to reduce
frame rate or the no. shift-in pixels or grayscale level for each pixel.
