INFOGRAPHICS: How does the touch screen phone
Technologies / / December 19, 2019
About that, at a phone screen is better, walk the constant disputes. Especially between the owners of Apple technology and those who prefer Android devices.
This is a simple infographics beautifully decomposes on shelves all the advantages of a touch screen type. Hopefully, with the purchase of a regular smartphone it will help you make the right choice and not to overpay bank.
Thus, an existing member of three types of touchscreens: resistive (Resistive), Capacitive (Capacitive) and IR (Infrared)
Resistive (Resistive)
Phones with resistive screens: Samsung Messager Touch, Samsung Instinct, HTC Touch Diamond, LG Dare
How do they work? Small dots are separated more layers of material which transmits current. When the top layer is pressed onto the flexible bottom layer, the electric current varies and an impact position is calculated, i.e. touch.
How much is the production? The manufacturing costs of the resistive touch screen is not very big - $.
Screen material. The layer of flexible material (typically made of polyester film) is superimposed on the glass.
Tools impact. Fingers, gloved fingers or a stylus.
Outdoor visibility. Poor visibility in sunny weather.
Possibility multizhestov. Not.
Durability. For it is the cost of the screen for a long time. Easily scratched and prone to other small damages. Quite quickly it wears out and requires replacement.
capacitive
Phones with capacitive touch screens: Huawei Ascend, Sanyo Zio, iPhone, HTC Hero, DROID Eris, Palm Pre, Blackberry Storm.
How do they work? The current broadcast of the corners of the screen. When a finger touches the screen, it changes the direction of the current and thus the calculated touch location.
How much is the production? Quite expensive - $$.
Screen material. Glass.
Tools impact. Only fingers without gloves.
Outdoor visibility. Visibility is good on a sunny day.
Possibility multizhestov. There is.
Durability. It serves for a long time. Glass destroyed only from serious damage.
infrared
Phones with infrared touch screens: Samsung U600 (heat), Neonode N2 (optical).
How do they work? To react the heat-sensitive screen, it is necessary to touch a warm object. Optical display uses a grid of invisible sensors directly above the screen. The touch point is calculated based on the point where the x-y axis is broken.
How much is the production? Very expensive - $$$.
Screen material. Glass.
Tools impact. Optical - fingers, gloves and stylus. Heat-sensitive - warm gloves without fingers.
Outdoor visibility. Visibility in sunny weather is good, but strong sunlight affects the productivity and accuracy.
Possibility multizhestov. Yes.
Durability. It serves for a long time. Glass destroyed only from serious damage.
