Due to the large variety of keyboard possibilities, if you do not see what you want listed below please do not hesitate to contact us.

Video Signal Processing
 LCD Monitor Controller Boards
 Low Cost

Our economical entry-level products support single input DVI/VGA sources in a small size. We have a wide variety of boards available for different applications and markets. Technical support for these boards come from the United States and we are happy to customize them to meet your needs.

 High Resolution

Our middle range products support high-resolution inputs (1920x1200) and have support for board health monitoring, built in LED’s and touchscreen controllers. These products usually are integrated into medical systems or other demanding embedded applications.

 High Capability

At the top end of our LCD monitor controller product line are our high capability boards. These boards support multiple video input sources along with high resolutions and advanced firmware for complex customer requirements. Advanced functionality boards generally support picture in picture.  

Video – Overlay, Mixing, Scaling and Switching Products

Due to the challenging demands of our customers, we have created a family of FPGA based signal processing boards. These boards are capable of video overlay, scaling and mixing. Typical applications include end of life support for LCD panels and casino player tracking video overlay.

Medical / Industrial Monitors
Medical Monitors 

Touchstone Technology has a long history of manufacturing monitors for the medical industry. Our monitors are used in market segments ranging from x-ray review and capture to nursing central stations. With our years of experience, regulatory compliance is easy to achieve. All monitors are designed with high reliability and use components with a minimum of 5-year availability.

Gaming Monitors 

Touchstone Technology has supplied monitors to many of the leading companies in the gaming industry and we understand the regulatory and reliability needs. We have a wide variety of gaming monitors available in both touchscreen and non-touchscreen styles. Monitor sizes range from 6.2” player tracking displays up to 26”.

Custom Monitors  

Touchstone Technology’s strongest capability is the creation of custom products that meet customer specific requirements. In the past, we have developed monitors for applications ranging from self-service kiosks to in-flight entertainment seat back video monitors. We have full design capabilities in house (electronics, sheet metal, plastics, cables) and we can completely design a monitor according to your needs. Extensive reuses of components (video controllers and plastics) allow us to save time to market and achieve economies of scale with lower volume products.

LED Lighting Products

LED lighting is widely replacing fluorescent light bulbs in a variety of applications. Touchstone Technology has been on the forefront of these efforts in the industrial display marketplace.

Current products include:

USB and RS-232 LED controllers
DC/DC LED current controlled power supplies
LED lighting strips

 Touch Controllers

Touchstone Technology has a wide line of Touch Controllers available ranging from standalone products to licensable design solutions.

Touch technologies that are supported include:

4-5-8 wire resistive touchscreens
Projected capacitive touchscreens
Surface capacitive touchscreens
Various interface protocols including USB, RS-232, RS-485, CAN bus, I2C

We also manufacture translation boards that map a touchscreen protocol to another. This allows host computer software to remain unchanged and have projected capacitive to the surface acoustic wave.
