Capacitive Touch Display

Why Use Fiber Optics for Capacitive Touch Backlighting

Touch screen displays are becoming more popular in the market with touchscreen phones, computers, and other display devices. Capacitive touch displays are a type of touch screen display that work with anything that has an electrical charge like your finger tip. As with other displays, lighting is important to be able to see the display.


Lumitex designs and manufactures custom backlighting solutions for capacitive touch displays across many different types of applications including:

  • Consumer/Commercial Appliances
  • Consumer Electronics
  • Control Panels
  • Industrial Displays

Why our Technology is Ideal for Capacitive Touch

When backlighting a capacitive touch display, light is placed between the sensor and the cover layer of the screen interrupting the capacitive field. It is essential to choose a backlight that creates minimal capacitive field interruption while still being able to enhance the overall efficiency and design of the application. Our proprietary technologies offer many unique benefits to Capacitive Touch Displays:


Low-Profile - As thin as .2mm to reduce space needed and interruption to the capacitive field


Efficient - Bright, efficient and low power. We work with our customers to optimize the overall design to be power efficient and meet power requirements


Flexibility of Design

  • Adaptable to a variety of sizes, shapes and colors in a very thin format
  • Flexible materials can conform to various contours
  • Scratch Resistant Integration Application Examples
