TECH READS: How Touchscreens work.
So, yeah! As I discussed earlier we will be looking into different aspects of technology each week!Today we will look at how Touch screens actually work!
1. Screens have a grid of tiny driving lines going through them.
2. Each of these contain a small voltage.
3. When you touch them, it causes a change in the local electric field.
4. The voltage disruption is detected by a controller and it identifies the axis. Thus, it carries out the function it it supposed to.
Next time you use your phone, remember All these things happen right under your nose!
That was a really small and Very fascinating one. Wait for the Next tech reads until next week.
Keep Reading cuz readers are winners!
