Four wire is the simplest and oldest design to accomplish this intersection. The voltage is applied alternately to both conductive layers, each in a different orientation. Therefore, there are four wires for connection required, which gives its name.
Four Wire has the disadvantage of quickly decreasing precision in detecting the pressure point. The outer polyester layer of the touch screen is mechanically loaded by its use. Thus, the conductive coating its inner side loses uniformity. This coating is of Four wire but a measure of the position of the pressure point as shown by Laptop Screen Repairs.
Five Wire
Five wire avoids the deterioration of precision by the outer conductive layer, it is not used as a measure for the position of the pressure point. It is used only to forward the tension of the lower layer and is connected with an additional fifth wire.
The other four ports are located at the corners of the lower layer. Two adjacent vertices are directly connected and the the voltage is applied to the two corner pairs. Between the first and second measurement is switched to the second possible set of corner pairs thanks to Laptop Screen Repairs.
Six and Seven Wire are variations of Five Wire, while Eight Wire is a variation of Four Wire. In these designs, the additional lines are used to separate the measured voltages (principle of the four-wire measurement).
Universal port replicators, which are connected via a Universal Serial Bus and are sometimes referred to as USB docking stations. This requires no special properties of the notebook, which is why such a replicator can be generally used in combination with all notebooks. The various interfaces are thereby connected via the USB converter, which attracts some serious limitations to the performance itself. A port replicator via USB is indeed universally usable, but has a few significant drawbacks:
The graphics performance (speed and maximum resolution) graphics solutions of the docking station are compared with the integrated graphics card in the notebook significantly worse. All USB devices share the maximum bandwidth, resulting particularly in network interfaces to speed losses.
For these reasons at least two to three cables are used in stationary use (external monitor, USB port replicator, power) in practice mostly. Similar replicators exist for the express card slot, which then fall back on the USB and PCIe interface and the connection of these functions are comparable.
The USB docking stations are gradually replaced by “Thunderbolt docking stations” because at the Thunderbolt interface without loss in performance multiple protocols including Monitor, Internet, printers, boxes, disks, etc., can be operated simultaneously.
