3 / 21 page 點晶科技股份有限公司 SILICON TOUCH TECHNOLOGY INC. DM163 8x3-CHANNEL CONSTANT CURRENT LED DRIVERS Version: A.004 Page 2 Block Diagram Figure 1. Functional Schematic of Whole Chip The schematic of DM163 comprises of several fundamental units as shown in Figure 1. The grayscale data are input onto the DM163 by the SIN pin and transferred according to the synchronous clock DCK. Meanwhile, in order to separate the data into two groups, SELBK is designed as a switch control pin. When a sequence of data is already transferred onto the chip, the LAT_B=”H” is set to convey it into the comparator unit. Compared with the counter signals, the grayscale data will determine the PWM control signal to display varied luminance at driver output. The Rext resistors are able to set diverse output current levels. The detailed schematic of each channel is shown as Figure 2. |
