| Embedded | Embedded devices are designed to be integrated or embedded into a larger device. Generally, they do not have housings since they are housed in the same enclosure as the device with which they interface. ATM screens are an example of embedded devices. | ||
| External | External devices are designed to operate externally to the device being controlled. They have their own housing and are used to interface to a device over a distance. Touch screen monitors are an example of external devices. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Screen Type: | |||
| Your choices are... | |||
| LCD / Flat Panel | An advanced type of computer monitor that uses a flat screen to provide full color images. The screen is based upon Liquid Crystal Display technology, which uses a liquid crystal solution between thin polarizing layers. An electric current passes through the liquid to align the crystals, either blocking light or allowing it to pass, creating an image on the screen. Because they use flat screens, LCD monitors have great space saving advantages over traditional CRT monitors. They also use less power and do not emit harmful radiation. | ||
| CRT | A type of computer monitor that uses a large picture tube, similar to a television. This is currently the most common type of PC monitor. The display works by moving an electron beam back and forth across the back of the screen to light up phosphor dots on the inside of the glass tube. By drawing many lines from the top to the bottom of the screen, an entire screen full of images is created. | ||

| External Connections: | |||
| Your choices are... | |||
| Serial Interface | Serial interfaces are computer boards or ports which transmit data one bit at a time over a single wire. RS232, RS422, and RS485 are common types. | ||
| Parallel Interface | Parallel interfaces are computer boards or ports which transmit multiple bits of data simultaneously, along different wires. | ||
| USB | Universal serial bus (USB) is the standard serial bus for low-to-medium speed peripheral-device connections to personal computers (PCs) and keyboards, mice, modems, printers, joysticks, audio functions, monitor controls, etc. | ||
| SCSI | Small computer systems interface (SCSI) is an intelligent, input/output (I/O), parallel, peripheral bus with a standard, device-independent protocol that allows many peripheral devices to be connected to a SCSI port. | ||
| Mouse Port | The device has a port for a mouse. | ||
| Other | Other unlisted, specialized, or proprietary configuration. | ||

Performance

|
|
| ||
| Pixel Pitch: | Refers to the resolution, may also be called dot pitch. The dot pitch is defined as the distance between the nearest phosphor dots of the same color. The dots are equidistant, so the phosphor dots form an equilateral triangle, with sides of the same length as the dot pitch and with angles of 60º. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Operating Temperature: | This is the full-required range of ambient operating temperature. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
| |||
| Sensor Type: | |||
| Your choices are... | |||
| Resistive | Resistive touch technology consists of a glass or acrylic panel that is coated with electrically conductive and resistive layers. The thin layers are separated by invisible separator dots. When operating, an electrical current moves through the screen. 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. | ||
| Capacitive | A capacitive touch screen consists of a glass panel with a capacitive (charge storing) material coating its surface. Circuits located at corners of the screen measure the capacitance of a person touching the overlay. Frequency changes are measured to determine the X and Y coordinates of the touch event. | ||
| Infrared | Infrared is similar to resistive, infrared screens project horizontal and vertical beams of infrared light over the surface of the screen. When a finger or other object breaks those beams, the X/Y coordinates are calculated. | ||
| Surface Acoustic Wave | Surface Acoustic Wave technology is one of the most advanced touch screen types. It is based on sending acoustic waves across a clear glass panel with a series of transducers and reflectors. When a finger touches the screen, the waves are absorbed, causing a touch event to be detected at that point. | ||
| Strain Gauge | The screen is spring mounted on the four corners and strain gauges are used to determine deflection when the screen is touched. This technology can also measure the Z-axis. | ||
| Other | Other unlisted or proprietary sensor type. | ||

| |||
| Image Resolution (In Pixels): | This is a measurement of how sharp the image will appear. The higher the resolution, the sharper the image. | ||

| Features / Applications | |||
| Your choices are... | |||
| Software Driver? | Software that runs on a PC to translate hardware events into something that the PC's Operating System can understand. In the case of a touch screen system, the software driver translates touch events into mouse events that the system can understand. | ||
| Uses a Stylus? | A pen-like pointing device that can be used with a touch screen system. A stylus usually has a much finer point than a finger and therefore is useful for more precise touch screen operation. | ||
| Backlit Screen? | Screen illuminates for use in low light situations. | ||
| Speakers Included? | Speakers mounted directly in touch screen module. | ||
| Integrated Keypad Interface? | Display has an integrated keyboard or a number pad as an input. | ||
| Suitable for Extreme Environment Applications? | Is protected against corrosive elements, high humidity, etc. | ||
