The working principle of the rotary drum screen is relatively simple, and it involves the use of a rotating cylindrical screen that is fitted with sieves or perforated plates. 1. The wastewater to be treated is first fed into the inlet of the rotary drum screen, and as the drum rotates, the wastewater flows along its length.
How is an LCD Screen Made? To construct an LCD, the two glass substrates are prepared. On one substrate, ITO is typically deposited to form a transparent yet conductive layer (the electrode layer). Silicon is next deposited on top of the ITO layer along with the transistor parts. On the other layer, the color filter is made using RGB colored dots.
1、Structure: A series of infrared LEDs and corresponding photodetectors are installed along the screen's edges. 2、Working Principle: The LEDs emit infrared light, forming an invisible grid.
