To extend mobile life capacitive touch screen care and maintenance tips oled modules

The phone this necessity of life, continuous innovation to meet modern people increasingly high requirements. The entire mobile phone market today is basically a touch screen smart phone world, popular capacitive touch screen, from the earlier resistive touch screen and now touch screen mobile phone development can be described by leaps and bounds.COG LCD Display
Capacitive touch screen is the most sought after on the market today approved its structure is plated with a layer of transparent film conductor layer on a glass screen, and then the conductor layer with a protective glass, double glass design can completely protect the conductor layer and sensor.
Estimated that many people are curious capacitive touch screen is what principle he can sense touch, and react accordingly. Here we take a look at the working principle of the capacitive touch screen.
When the fingers touch the metal layer formed body electric, users and the surface of the touch screen to a low voltage, high-frequency current, capacitance is directly conductor, so fingers away from the contact point a small current. The current points from the four corners of the touch screen on electrode outflow is proportional to the square of the distance, and the current flows through four electrodes with a finger to the controller through the accurate calculation of the four current ratio, come to the touch point position .TFT Lcd Modules
Capacitive screen nice, but the point is accurate, and easier to support multi-touch, but as we all know, good things tend to be more delicate, care has become a problem, master points capacitive screen use and maintenance considerations, so that we encounter similar problems in their daily lives will not be blind panic.
