3.6 Electrical Block Diagram

According to the product idea, 15"" LCD panel and touchscreen are the
basic two components in this product. Besides, in order to reduce the depth
of LCD touch monitor and solve cooling problem at the same time, a DC
input is designed to remove the AC switching power supply. An AC
switching power adapter of full range is used to provide DC voltage of the
monitor.
The LCD touch monitor is constructed based on steel open frame
architecture. It consists of a 15"" LCD panel, an DC to AC inverter board to
support a set of cold cathode fluorescent light (CCFL), an analog to digital
converter board (ADC) to convert analog RGB signals to digital ones, and a
touchscreen used as a pointing device. A metal chassis supports the whole
module.
