四线触摸屏不考虑电极抽头引线的寄生电阻和驱动电极的电路。该电阻不包括在ITO电阻中，并且该电阻会因环境温度的影响而波动，这很可能会影响计算的准确性。因此，有了八线电阻触摸屏的概念。

四线/八线电阻触摸屏的优点在于，它不仅可以计算水平的X和Y坐标，还可以通过一系列方法测量纵向的Z坐标，即手指的压力。这是通过测量纵向接触电阻Rtouch得到的。因为当接触发生时，接触电阻与压力成反比。力越大，接触电阻越小。该电阻的测量值可用来量化接触压力。

四线/八线电阻式触摸屏的缺点是不够耐用。长时间触摸和按压会损坏设备。因为上层PET和IT0每次接触都会变形，而ITO材料在经常变形的时候比较脆，容易损坏。一旦ITO层破裂，导电的均匀性被破坏，推导上述坐标的比例等效性不复存在。这种破损经常发生在容易触摸的地方，比如“确认”键的位置。另一个缺点是附着在PET可移动基板上的ITO没有完全氧化。一旦暴露在潮湿或高温下，氧化使电阻上升，这也破坏了电导率均匀性，并导致坐标计算误差，即“漂移现象”。这就产生了五线电阻屏的概念。

The four-wire touch screen does not consider the parasitic resistance of the electrode tap lead and the circuit driving the electrode. This resistance is not included in the ITO resistance, and the resistance will fluctuate due to the influence of ambient temperature, which will most likely affect the accuracy of the calculation. Therefore, the eight-wire resistive touch screen concept.

The advantage of the four-wire/eight-wire resistive touch screen is that it can not only calculate the horizontal X and Y coordinates, but also measure the longitudinal Z coordinates, i.e. the pressure of the finger, through a series of methods. This is obtained by measuring the longitudinal contact resistance Rtouch. Because when contact occurs, the contact resistance is inversely proportional to the pressure. The greater the force, the smaller the contact resistance. The measured value of this resistance can be used to quantify the contact pressure.

The disadvantage of the four-wire/eight-wire resistive touch screen is that it is not durable enough. Prolonged touching and pressing can damage the device. Because the upper PET and IT0 will be deformed every time they contact, and ITO material is brittle and easy to damage when it is often deformed. Once the ITO layer breaks, the homogeneity of the conduction is destroyed, and the proportional equivalence in deriving the above coordinates ceases to exist. This breakage occurs frequently in areas where it is easy to touch, such as the position of the "confirm" key. Another disadvantage is that the ITO attached to the PET removable substrate is not completely oxidized. Once exposed to humidity or high temperatures, oxidation causes the resistance to rise, which also destroys the conductivity uniformity and causes an error in the calculation of coordinates, that is, the "drift phenomenon." This gave rise to the concept of a five-wire resistance screen.
