DSi do enrich our life through countless great games and extra multi entertainment features. However, annoying troubles may drop in on if we do something unexpected to DSi by accident. One of the most unlucky thing should be the deflection of touch screen. Every time you want to touch the middle of the screen but the system considers you are hitting the section 2 centimeters to the left, and that often stirkes down your mood. Everything always happens for a reason, let’s see why this occurs before you decide to make a replacement.

The four-wire resistive touch screen technology is used on the DSi bottom screen (also known as touch screen), which consists of one air-filled seperator and several electrically layers. When pressure is applied to the screen the layers are pressed together, causing a change in the electrical current and a touch event to be registered, thus achieving one operation in game.

The four-wire resistive touch screen technology gains lots of advantages while performing as a constituent part of handheld console, like very little response time, durable surface and can be used in a variety of environments. There are still something you should pay attention to protect it from sharp object or many a time fierce touch. What you should take care the most are the two layers on the touch screen. A screen guard in solid quality and gentle manner will be good to extend your DSi screen life.
