The difference between multi-touch and single-touch technology oled module

For consumer electronics products, how complex user control action into intuitive, convenient and produce experience, is faced with the ultimate challenge of user interface design. The user interface must be designed to take into account the needs of the users taste, smell, sight, hearing and touch the five senses, and also take into account user needs the device or system. Most of the products launched in the market are the user's visual and tactile be dealt with separately. Click and Scroll features more advanced from the above simple button phone keypad, computer keyboard, household appliances and even TV remote control to adjust the volume slider, wheel and track plate above, the output location and the user input position is very different . If we make the input and output fully meet consistent the fundamental advantages manifestation of this is the touch-screen.display lcd 20x4
Visual and tactile (input and output) fully meet the consensus seems simple enough, but it is hard. Transparent touch screen feature allows users to direct "touch" on the display, people no longer have to go to the electronic equipment button. This is a revolutionary change, this manipulation allows direct control of the user's fingertips powerful operating systems and applications. The touch screen is divided into three categories: single-point touch; multi-touch recognition finger direction; multi-touch recognition finger position.
Touch screen user interface brings two major benefits, equipment design space has been optimized, in particular, is conducive to small devices, because in the same area at the same time "Install" screen, and buttons; button can bind to the operating system in any application, "button" equipment can achieve infinite plurality. The function is mainly built on the basis of resistive touch screen technology has been widely promoted in a variety of applications in the consumer electronics, airport kiosks, grocery POS terminals and car GPS systems.
Although single-point touch screen and resistive touch screen technology is very surprising, but it still has two major drawbacks, resistive technology relies on the physical movement of the touch screen, after normal wear and tear of aging, performance will drop; this technology only supports single-touch. Why is the interaction of the user and the device can only be limited to a finger? Apple's user interface revolution has made an invaluable contribution to the launch of the iPhone using inductive-capacitive touch screen. Even if miniaturization of devices such as smart phones, in order to give full play to the applications and operating system functions, and also requires a plurality of fingers in order to achieve the best availability.16x2 lcd
