Custom Display RFQ Preparation
Provide Enough Evidence to Define the Quotation Boundary
A request for “a custom 10.1-inch LCD” does not yet define a buildable or quotable product. Engineering needs the equipment application, fixed mechanical envelope, image format, host interface, optical and touch stack, operating environment, compliance scope, quantities and schedule. These inputs determine whether the project should use a standard module, a modified platform or a full custom design.
First Identify the Type of Commercial Response Needed
Feasibility screening
Use when the project is early and several display architectures are still possible. Provide the application, size or envelope, resolution, host, brightness, touch, environment and volume range. The response should identify viable routes and missing decisions rather than present an unconditional production price.
Preliminary budget
Use for internal planning when some specifications remain open. Every estimate should list assumptions, quantity basis, tooling/NRE boundary, exclusions and validity. It is not a final quotation or approval to freeze mechanics.
Formal quotation
Use after the specification and quantity tier are sufficiently defined. The quote should identify the exact product or custom scope, samples, MOQ, NRE/tooling, unit price basis, lead time, validation responsibility and commercial terms.
Minimum Information for Initial Engineering Screening
| Input | Minimum useful detail | Decision it supports |
|---|---|---|
| Application | Equipment type, operator, installation and main use case | Routes industrial, outdoor, automotive, medical, portable or other requirements. |
| Display format | Target diagonal or fixed outline/active area, resolution and orientation | Identifies standard platforms and mechanical feasibility. |
| Host | Processor, mainboard or controller and available display output | Determines whether native RGB, LVDS, MIPI DSI, eDP or a bridge/controller is required. |
| Optical target | Indoor/outdoor environment, brightness range and viewing direction | Frames the panel, backlight, coating, bonding and thermal work. |
| Touch | None, PCAP or resistive; finger, glove, stylus, water and cover-glass needs | Defines the sensor, controller, stack and validation path. |
| Environment | Operating/storage temperature and known moisture, vibration or EMC exposure | Filters unsuitable consumer-grade platforms and identifies testing needs. |
| Commercial scope | Sample quantity, estimated annual quantity, target production date and lifecycle | Determines whether the technical route is commercially practical. |
Mechanical Package: Define What Cannot Change
Provide a dimensioned PDF drawing whenever the equipment enclosure, viewing window or mounting system already exists. Mark the maximum outline, thickness, active area, bezel, mounting features, connector and FPC location, cable path and keep-out zones. If the project includes a cover lens, provide its outline, thickness, holes, edge treatment, printing and tolerance requirements.
CAD files can support a later mechanical review, but they should not replace a controlled dimensioned drawing. Identify the drawing revision and units. If only a sample or damaged display is available, send clear front, rear, side and label photographs with reference dimensions, while treating measurements as provisional until an approved drawing exists.
Electrical and Interface Package
- Host processor, GPU, SBC, controller board or bridge model.
- Native display outputs and any interface preference.
- Resolution, refresh rate, pixel format, color depth and orientation.
- Connector, pinout, supply rails, logic voltage, current budget and power sequence.
- LVDS channel/mapping, MIPI lane/mode/initialization, eDP lane/link/AUX/HPD or RGB/SPI timing as applicable.
- Backlight current, voltage, enable, PWM/dimming and thermal constraints.
- Required controller-board, cable, firmware, driver or BIOS/device-tree responsibility.
If the project starts from an existing panel, include the full model suffix and datasheet. Do not shorten the model or assume that a matching connector establishes electrical compatibility.
Optical Performance and Viewing Environment
State where the display will be viewed: controlled indoor light, near a window, shaded outdoor use, intermittent direct sun or continuous exposed sun. Define target luminance, viewing direction, contrast priorities, color requirements and whether the value must be measured at the bare LCD or through the completed touch and cover stack.
List requested AG, AR or AF treatment, optical bonding or air bonding, protective window and any polarizer constraints. Higher brightness changes backlight power, heat and expected life, so the enclosure, duty cycle, dimming strategy and thermal path are part of the quote boundary.
Touch, Cover Glass and Bonding Inputs
For PCAP, define cover-glass material and thickness, border printing, touch points, controller interface, glove and stylus types, liquid behavior, palm/false-touch criteria and operating-system support. For resistive touch, define wire configuration, input tool, actuation and durability expectations, edge sealing and controller output.
Specify whether LCDind should quote the bare LCD, LCD plus touch sensor, bonded display stack or a complete display/controller kit. State whether cosmetic appearance, bonding bubbles, optical uniformity, cover-lens tolerances or service replacement require written acceptance criteria.
Environmental, Reliability and Compliance Scope
Temperature and humidity
Provide operating and storage limits, cold-start requirement, dwell time, thermal cycling, humidity, condensation and internal enclosure temperature where known.
Mechanical exposure
Identify vibration, shock, drop, bezel load, impact, cable retention, cleaning and abrasion requirements, including the applicable equipment test method when available.
Electrical environment
Describe motors, inverters, radios, chargers, long cables, grounding, ESD/EFT or conducted-noise requirements that can affect the display and touch controller.
Compliance and records
List required material declarations, certificates, industry approvals, inspection records or customer-specific documentation. Do not assume they are included in a standard module price.
Quantities, Tooling and Schedule Are Engineering Inputs
Quantity is not only a purchasing field. Sample quantity, first production order and annual forecast influence panel platform, component sourcing, custom FPC feasibility, cover-glass process, controller choice, inspection, MOQ, NRE/tooling allocation and lead time. Include the expected program life and whether demand is stable, phased or service-only.
State the date needed for feasibility feedback, first samples, validation units and production. If the requested schedule is shorter than a custom development cycle, engineering can evaluate a standard or modified module as a bridge, but the temporary and production solutions must remain clearly identified.
Standard Modification or Full Custom Development?
| Route | Typical scope | RFQ evidence required |
|---|---|---|
| Standard module | Existing LCD and interface with no design change | Exact model/specification, quantity, application and delivery requirement. |
| Value-added integration | Touch, cover glass, bonding, coating, cable or controller matched to a standard LCD | Stack drawing, cosmetic/optical criteria, controller interface, environment and quantities. |
| Modified platform | Custom FPC, pinout, backlight, connector or mechanical feature around an existing panel architecture | Controlled drawings, electrical definition, tolerances, tooling/NRE scope and validation plan. |
| Full custom display | New glass/cell/module architecture or non-standard size and resolution | Complete product requirement, business volume, lifecycle, development schedule, tooling budget and qualification responsibility. |
How Missing Information Should Be Handled
Do not fill a missing specification with an unstated assumption. Mark it as open, propose a realistic range and identify who must decide it. If a preliminary budget is possible, list every assumption and exclusion in the response. Formal quotation should wait until the open items that materially affect cost, feasibility or validation are controlled.
A one-business-day response target should mean acknowledgement and identification of missing inputs, not a guarantee that every custom project can receive an engineering-approved price within that period.

Custom LCD Quotation FAQ
Can LCDind quote a custom LCD from only the size and resolution?
Those details can support an initial screening, but a reliable quotation normally also requires the mechanical envelope, host interface, brightness, touch and cover stack, operating environment, quantities, schedule and the scope of any controller or firmware work.
Is a drawing required before requesting a custom LCD quote?
A dimensioned drawing is strongly recommended when the enclosure, active area, connector, FPC, mounting or cover glass cannot change. A written requirement can start feasibility screening, but missing dimensions will remain assumptions until confirmed.
Why are sample quantity and annual quantity required?
They affect the suitable technical route, component sourcing, tooling or NRE allocation, MOQ, production process, test scope, lead time and whether a standard module modification or full custom design is commercially practical.
Can a preliminary budget be provided before every detail is fixed?
Sometimes, if the assumptions and exclusions are stated clearly. A preliminary budget is not a final quotation and should not be used to approve tooling or production until the specification, quantities, validation scope and commercial terms are confirmed.
What files should be included in a custom LCD RFQ package?
Include the requirement summary, dimensioned PDF drawing, existing LCD datasheet if applicable, host or controller information, interface and pinout, cover-glass drawing, touch and bonding requirements, environmental and compliance criteria, sample quantity, annual quantity and target schedule.
