TIP-4131SCE-1

Vishay Dale Electronics TIP products TIP-4131SCE-1 are infrared touch panels designed to fit most flat panel display technologies. The touch panels consist of infrared emitters and detectors, scanning electronics, a microprocessor based controller, a bezel and optical filter assembly, and hardware to mount the touch panel assembly to the flat panel display.

These touch panels TIP-4131SCE-1 are ideal for many applications including medical instrumentation, machine or process controllers, point of sale devices, public information displays, banking terminals,and military.

Each panel TIP-4131SCE-1 has infrared LED emitters and phototransistors along the X and Y axes, forming a grid of infrared light beams across the face of the display. The first two numbers of the TIP "matrix" number specify the number of X axis (vertical) beams, and the last two numbers specify the number of Y (horizontal) beams. The controller scans the emitter/detector pairs one at a time and determines whether both X and Y beams are blocked, indicating that a finger or stylus is present.

(When beams are blocked on only one axis, they are ignored and not reported.) The controller determines the coordinatesof the touch point and reports it to the host computer. By interpolating, a "virtual" beam between two physical beams, the number of touch points on each axis is effectively doubled.

When an odd number of beams along either axis is blocked,the coordinate of the center physical beam is reported. When an even number of beams is blocked, the coordinate of the virtual beam in the center of the blocked beams is calculated and reported.

Vishay Dale's TIP touch panels have a unique patented scanning and logic system that make them virtually immune to most lighting environments. The touch controller supports ENTER, EXIT, CONTINUOUS,and TRACKING report modes or combinations of these modes. The controller also has a beeper output. Hardware handshaking, software handshaking, baud rates, and X, Y coordinate invert features are jumper selected. The user initializes the desired report modes, coordinates are reported automatically or upon request as needed. Several optical filters are standard to provide the most cost effective filter for each application. "Non-standard" filters may be specified as well.

The filter increases the contrast ratio of the display and protects the display face and electronics. Vishay Dale can assist in recommending the optimum filter based on years of experience as a display manufacturer. The perimeter of the filter is bonded to the bezel, and a bezel to front panel gasket is included to provide a splash proof seal.Optional PC based software provides simple touch panel integration (see ordering instructions).
