Design Integration for Industrial Touch Products
Engineering decisions are coordinated across cover glass, PCAP sensor, FPC, controller, display, optical bonding, mechanical structure and system interfaces.

Documented 15.6-inch PCAP touch display reference design
A controlled EverGlory module specification and engineering drawing document the integration of a projected-capacitive touch panel, TFT LCD, FPC, controller interface and bonded mechanical stack. The technical summary below is drawn from that controlled source; it is not a conceptual rendering.

| Module stack | 2.9 mm touch panel; 12.7 mm total thickness | Supports bonding, enclosure and installation review |
| Touch system | 10-point PCAP; USB; 5 V typical | Defines controller and host-interface requirements |
| Touch performance targets | ≥100 Hz report rate; ≤25 ms response; ±2 mm linearity | Provides project-level functional acceptance criteria |
| Display | 1920 × 1080; 500 cd/m² typical; 1000:1 typical contrast | Defines the optical and display baseline |
| Materials and optics | >85% transmittance; ≥6H cover hardness; ≥4B ink adhesion | Links material selection to defined inspection criteria |
Controlled drawing content
Front, side and rear views identify the cover lens, LCD outline, active and viewing areas, FPC and connector locations, stack-up and dimensional tolerances.
Controlled source verified
Electrical and optical definition
The specification records touch interface, supply, report rate, response, LCD power, resolution, luminance, contrast and material requirements.
Specification content verified
Validation and handling definition
The same package defines reliability items, ESD checks, appearance inspection, FPC handling, cleaning and packaging precautions.
Engineering coverage verified
Reference-use rule: this public summary demonstrates design and documentation capability. Final dimensions, LCD, controller, optical-bonding stack, FPC, tolerances, interface and validation plan are confirmed for each project. Customer identifiers, internal part numbers and the complete production drawing are not published.

How to read these values: the figures demonstrate design, tolerance, FPC and controller integration capability. Temperature, hardness and optical values shown on a drawing are design requirements; a tested-performance claim requires the matching validation record.

Engineering handoff from drawing to sample
1. Define
Record the application, environment, mechanical envelope, interfaces and validation requirements.
2. Review
Check stack-up, dimensions, FPC routing, controller, grounding, bonding and assembly risks.
3. Release
Freeze the approved drawing revision and sample configuration before prototype manufacture.
4. Validate
Run the agreed functional and engineering checks and close the resulting issue list.
5. Transfer
Release the production baseline, inspection criteria and change-control requirements.
6. Support
Maintain traceable revisions when the host system, LCD, interface or mechanical design changes.
Controlled engineering references
Real drawing data, presented in a public review format
The summaries below are derived from controlled EverGlory engineering files. They show the level of mechanical, optical, electrical and environmental definition available before sample release while keeping customer-specific information out of the public page.
10.1-inch projected-capacitive touch panel
Cover lens: 2.0 mm. Sensor: 0.55 ±0.05 mm. Total stack: 2.75 ±0.2 mm. The source drawing also defines the FPC/controller position, front/side/back views, dimensional tolerances and approval fields.
Controlled source: drawing EG-SY-10.1-A-1609V1, issued 24 April 2020. Optical targets include >85% transmittance and >6H surface hardness. Values apply to this reference drawing only.
10.1-inch high-brightness touch monitor
The controlled specification defines a −20°C to +70°C operating target, −30°C to +80°C storage target, capacitive USB touch and a sheet-metal enclosure with external or wall mounting.
Specification boundary: contact ±4 kV and air ±8 kV, performance criterion B, are specified reference requirements in this engineering file. A compliance statement still requires the matching completed test record.

Frequently asked questions
Can you customize the cover glass, FPC and touch interface?
These items can be reviewed as part of an OEM PCAP or touch-display project. Feasibility depends on the target dimensions, controller, host system, tooling and qualification requirements.
Why are public reference drawings marked for reference only?
They are de-identified capability examples. Only the project-specific drawing revision approved by both parties can be used for sample, purchasing and production control.
What should be checked before optical bonding?
Confirm the LCD outline and viewing area, cover-glass design, bonding material, total thickness, tolerance stack-up, flatness, sealing, visual criteria and installation stress.
