SETTING GRAYSCALE
The TLC5941 can adjust the brightness of each channel OUTn using a PWM control scheme. The use of 12 bits
per channel results in 4096 different brightness steps, from 0% to 100% brightness.
Equation 4
determines the
brightness level for each output n:

Figure 7. Dot Correction Data Packet Format
To input data into the dot correction register, MODE must be set to V
CC
. The internal input shift register is then
set to 96-bit width. After all serial data are clocked in, a rising edge of XLAT is used to latch the data into the dot
correction register.
Figure 8
shows the dc data input timing chart.

where:
GSn = the programmed grayscale value for output n (GSn = 0 to 4095)
n = 0 to 15
Grayscale data for all OUTn
The input shift register enters grayscale data into the grayscale register for all channels simultaneously. The
complete grayscale data format consists of 16 x 12 bit words, which forms a 192-bit wide data packet (see
Figure 9
). The data packet must be clocked in with the MSB first.
