Touchscreens: Resistive vs Capacitive
Since the advent of touchscreens in the late 1960’s touchscreens have undergone myriad number of advancements. From scratch-resistant screens to ultra-sensitive ones, these interfaces just speak volumes about the way technology has evolved.
Touchscreens come in two variants: Resistive and Capacitive. The nomenclature reflects the working of the two varieties. Resistive touchscreens were the first ones to be used on smart phones and tablets, though they are not out-dates ones now.
Here is a comparison of the two popular technologies used in building a touchscreen. Though it is not an absolutely perfect guide, it will give you an idea of which one is better in which parameter.
| Parameter | Resistive touchscreen | Capacitive touchscreen |
|---|---|---|
| Age | Relatively older technology | Newer technology |
| Accuracy | More | Less accurate, requires special stylus for better point detection |
| Durability | More | Less |
| Clarity | Less in normal daylight | More due to use of less number of layers |
| Responsiveness | More pressure requirement makes it less responsive | Though it is more responsive, it is less durable and hence requires more pressure as it gets older |
| Cost | Lower | Higher |
| Touch accessory | Any pointed object will work fine | Special stylus is required for better operability. Many modern touchscreens do not work if any objects other than human fingers are used. |
| Typical working temperature | Works best between -15℃ to 55℃ | Works best between 0℃ to 35℃ |
| Robustness | Though a resistive screen is responsive to any kind of pointed device, it has a vulnerability to force by pointed objects. More force will eventually make it difficult to use. However, it is sturdy enough to sustain the adverse effects of a fall | As the outer layer is made up of glass, it is resistant to scratches and is easy to clean. However, it is vulnerable to the shattering effect of a fall. |
