Rugged tablets and handheld computers go everywhere their users do: into sunlight, rain, freezers and onto concrete floors. DCL Technologies, Inc. (DCLTEK) supplies the embedded display and touch stack for industrial mobile computing, built for durability, sunlight readability that doesn’t drain the battery, and touch that works with water, gloves and cold.

What we supply

Small and mid-size TFT displays: handheld and tablet sizes with MIPI, eDP and LVDS interfaces.
Touch panels for mobile devices: PCAP from 2″ to 13″ for handhelds and tablets, tuned for water, gloves and cold.
Optical bonding: for sunlight readability and drop resistance.
FPC and cable assemblies: custom FPC length and orientation and internal cabling.

What we design for

  • Sunlight readability without draining the battery
  • Ambient light sensing and backlight dimming
  • Drop, shock and vibration resistance
  • Glove and wet touch
  • Wide operating temperature, including cold storage use
  • MIPI DSI integration support

Durable and readable in the field

Durability. Optical bonding locks the cover glass, touch sensor and display into one stack for better drop, shock and vibration resistance, behind chemically strengthened cover glass.
Sunlight readability through efficient backlight design. High-efficiency LED backlights deliver the brightness outdoor work needs with less power and heat, and ambient light sensing with backlight dimming saves battery when full brightness isn’t needed. Transflective panels are also available for designs that use sunlight itself.
Anti-reflection and contrast enhancement. Anti-reflective coatings and optical bonding remove the reflections that wash out an image in daylight, raising contrast so the screen is readable without simply turning the backlight up.

Touch that works in real conditions

Water on the screen. PCAP touch is tuned to reject rain, spray and droplets so they don’t trigger false touches, while still tracking a wet finger.
Gloves. Touch sensitivity is tuned for the gloves your users actually wear, from thin nitrile to work gloves.
Cold environments. Touch is tuned for consistent response at the cold end of your operating range, paired with wide-temperature panels for freezers, cold storage and winter field work.

Questions customers ask

How do you make a tablet readable outdoors without killing battery life?

Brightness alone isn’t enough. Optical bonding and AR coatings cut the reflections that wash out the image, which often allows a lower-brightness backlight with less heat and power draw. Ambient light sensing and dimming save more.

Can you help us move to a MIPI display?

Yes. Many new panels use MIPI DSI. Our free Engineer’s Guide to MIPI DSI integration covers host requirements, board layout and bring-up, and our engineers support the design.

Can you customize a standard panel?

Yes. We commonly modify backlight brightness, FPC length and orientation, interface, cover glass and mounting. Any NRE or tooling is quoted up front.

Will touch work with water on the screen, with gloves, or in the cold?

Yes, when it is tuned for it. We tune PCAP touch to reject water droplets and spray while tracking a wet finger, set sensitivity for the gloves your users wear, and tune for consistent response at the cold end of your operating range, paired with wide-temperature panels.

What sizes of mobile touch panels do you offer?

PCAP touch panels for mobile devices from 2″ to 13″, covering handhelds through rugged tablets, with matching displays in MIPI, eDP and LVDS interfaces.
