9.2.1.1 System Structure
To build an LED display module with 240 × 180 pixels, 96 TLC6984s are required.
Figure 9-2 LED Display ModuleAs shown in Figure 9-2, the total module can be divided into 48 32 × 32 matrix. Each matrix includes two devices with stackable connection.
To achieve the best performance, TI suggests to distribute the redundant channels and lines to each 32 × 32 matrix. For this case, two Red/Green/Blue channels and two lines are not used in each matrix. And these unused pins can be floated. For the software, TI suggests zero data is to send to the unused channels. There is no must send the zero data to unused lines.
