Luminance belongs to the exact listed configuration. It is not a finished-system sunlight-readability, sealing, EMC or safety certification. “No TP” means no integrated touch panel is documented.

Published bonded configurations cover 3.5, 4.3, 5 and 10.1 inches. Compare the 10.1-inch touch assemblies separately from the 1000-nit no-touch base model. The current 7-inch models do not document integrated PCAP; additional touch or custom cover glass needs feasibility review.

Selection questions

Define the use condition before selecting a module.

Start with the cover lens, user interaction and environment, then confirm the touch controller, bonding stack and host interface. Use our PCAP versus resistive touchscreen guide when the input method is still open, the PCAP stack design guide for cover lens, glove, water, grounding and EMC review, and the washdown HMI guide when sealing and cleaning are part of the requirement.

Bonding and mechanical stack

Engineering answer:

PCAP suitability is determined by the complete touch stack, not by the sensor alone. Confirm the finished cover-lens stack, touch-controller communication, grounding, EMC conditions and enclosure tolerances before sample release.

Define the input method

Document bare-finger, glove, water, cleaning and stylus conditions before choosing between PCAP and resistive touch.

Review the optical and mechanical stack

Cover-glass thickness, artwork, bonding and enclosure tolerances affect both the user interface and the integration route.

Validate the host connection

Touch-controller communication, power, grounding and EMC constraints require confirmation against the selected module documentation.

Documentation & sample review

Confirm the evidence for the complete PCAP assembly

A published PCAP configuration is a candidate for review. Keep the display connection, touch connection, cover lens and bonding configuration together when requesting documents or approving a sample.

Published configuration reference

Trace the listed size, resolution, interface, luminance and touch construction to the linked model page and the DISEA standard module catalog, DS series 2026 V2.1. The catalog does not release your touch-controller settings, cover-lens drawing or glove and water performance.

View the published module catalog →

Exact bonded-assembly documents

For a 10.1-inch optical bonded display, request the display and touch connections separately, then confirm the assembly drawing, cover lens and applicable configuration. Keep these two model references separate.

Review the 10.1-inch document checklist →

Recorded touch validation

Document the exact glove, surface and water condition, host and controller configuration, grounding, enclosure and acceptance criteria used for the sample. Record the result and any open issue against that assembly, rather than treating a PCAP label as a tested capability.

Use the sample validation record (fillable PDF) →

Send the conditions that the sample must reproduce

Include the cover-lens drawing, intended gloves, cleaning or moisture exposure, host-board information and representative UI. The PCAP design guide explains these planning inputs; for equipment used by medical staff, continue with the medical-equipment display selection guide. Confirm release documents for the selected configuration before ordering production units.

PCAP design-in checklist

What must be defined around a capacitive touch TFT LCD?

A PCAP module is not only a display with a touch sensor. The cover lens, touch controller, grounding, host communication, bonding and enclosure create one interactive stack that must be approved together.

Compare PCAP and RTP →

User and input method

Document bare-finger, glove, moisture, cleaning and gesture expectations. If a stylus is required, define the type and operating behavior instead of using “stylus support” as a generic request.

Cover-lens construction

Provide the lens outline, thickness, material, edge treatment, printed border, viewing window and mounting concept. These inputs affect the sensor stack and the mechanical drawing.

Controller and host

Confirm the exact touch-controller part or approved alternative, communication path, supply, interrupt or reset requirements and software ownership from current documentation.

Grounding and EMC

Identify nearby power converters, motors, radios, metal frames and display cables. Grounding and controller tuning must be validated in the finished equipment, not only on an open bench.

Bonding and optical stack

Decide whether the supplied configuration is air-gap or optically bonded and verify the exact materials and tolerances. Use the optical bonding review before freezing the stack.

Mechanical release

Check sensor and lens outline, tail position, connector, adhesive zone, bezel pressure and assembly clearance. Route any required tail or pinout changes through a controlled FPC review.

Buyer questions

Capacitive touch TFT LCD FAQ

Can a PCAP touchscreen work with gloves or water?

It may be possible, but the result depends on the sensor, cover lens, controller capability, tuning, grounding, contamination and required glove type. Define the operating condition and validate it on the finished assembly.

Does every listed PCAP module include optical bonding?

No. Only rely on bonding when the exact product page and current documentation identify it. A PCAP sensor, a cover lens and optical bonding are separate configuration decisions.

Can the cover glass artwork and shape be customized?

These are engineering-review items. Send the lens drawing, viewing window, border artwork, thickness, edge requirements, mounting method and environment so feasibility can be reviewed without assuming a standard construction.

What should be validated before PCAP sample approval?

Verify touch response for intended users, controller communication, start-up and recovery, grounding and EMC behavior, display image quality, bonding or air-gap stack, enclosure pressure and the released mechanical drawing.

Need this requirement combined with touch, a custom FPC or cover glass?

Use the engineering review to combine optical, mechanical and electrical requirements before sampling.
