4.5 Inch 480x854 Capacitive Touch Screen Display With Gt911 Driver Ic For Handheld Devices

Product Specification:

Products Description:

A capacitive touch screen is a transparent layer of special metal conductive material on the glass surface. When a finger touches the metal layer, the capacitance of the contact will change, causing the frequency of the oscillator connected to it to change. By measuring the frequency change, the position of the touch can be determined and information can be obtained. Because capacitance varies with temperature, humidity, or grounding, its stability is poor, and drift often occurs. The touch screen is suitable for the debugging stage of system development.

Application:

Touch screen technology is the direct manipulation type of gesture-based technology. Direct manipulation is the ability to manipulate the digital world inside a screen. A Touch screen is an electronic visual display capable of detecting and locating a touch over its display area. This is generally referred to as touching the display of the device with a finger or hand. This technology is most widely used in computers, user interactive machines, smartphones, tablets, etc to replace most functions of the mouse and keyboard.

Features:

1)Durability

One of the major benefits of capacitive touch screens is that they’re strong and durable. In commercial applications, it’s likely that a touchscreen will encounter a great deal of use. The function of a suitably selected and designed capacitive touchscreen won’t be affected by daily issues such as dirt and fingerprint smudges. Also, with no moving parts, no front coatings, and mounted optics/transducers (unlike all other touch technologies) – projected capacitive touchscreens should last for the lifetime of the device or system…. especially when carefully selected and designed to meet the application requirements.

2)Reliability

Similarly, in the unlikely event that a capacitive touchscreen is scratched, it should still continue to function as normal unless the rear-mounted conductive matrix is damaged. This is because it continues to measure changes in the generated electrical field irrespective of such damage.

Natural Use

One of the main reasons the technology has been so successful in consumer electronics and now in commercial/industrial applications is because it is highly sensitive touch technology, and yet will only react to a finger or conductive stylus (meaning ‘false touches’ are unlikely). Resistive touchscreens require considerably more pressure than a capacitive touchscreen and optical or acoustic-based touchscreens can be affected by inanimate objects touching the screen (rain, leaves, neckties, cuffs, etc.)

3)Image Clarity

As projected capacitive touch screens are generally produced from clear, uncoated glass, with a matrix of microscopic conductors on the rear face, they generally provide a higher quality picture than most other touch technologies. This makes capacitive screens a good choice for the latest high definition and now, FHD and OLED displays.
