7inch character lcd display module
7inch character lcd display module is a device for alphanumeric displays, as on digital watches, using a pattern of tiny, sealed capsules which contain a transparent liquid crystal that becomes opaque when an electric field is applied to it: the contrast between transparent and opaque areas forms the image of a number, letter, etc.

Connection to other circuits
A standard television receiver screen, an LCD panel today in 2018, has over six million pixels, and they are all individually powered by a wire network embedded in the screen. The fine wires, or pathways, form a grid with vertical wires across the whole screen on one side of the screen and horizontal wires across the whole screen on the other side of the screen. To this grid each pixel has a positive connection on one side and a negative connection on the other side. So the total amount of wires needed is 3 x 1920 going vertically and 1080 going horizontally for a total of 6840 wires horizontally and vertically. That's three for red, green and blue and 1920 columns of pixels for each color for a total of 5760 wires going vertically and 1080 rows of wires going horizontally. For a panel that is 28.8 inches (73 centimeters) wide, that means a wire density of 200 wires per inch along the horizontal edge.
