CDTech is a custom LCD manufacturer that can perform secondary cutting of standard LCDs to unusual sizes, as well as provide FPC/Interface, backlight, touch screen, and cover glass customization. The Company Profile for CDTech describes second-cutting technology in use at the company, and the Solution page describes an engineering process that takes products through prototyping, design, testing, and manufacturing. Newhaven Display features extensive display modification with a dedicated engineer; CXW Display custom LCD modules; and Keetronics rugged display and HMI solutions. Key suppliers for unusual applications such as industrial, medical, automotive, and home automation projects are selected based on approved drawings, test plans, and application-specific documentation. Note that CDTech lists ISO 9001, ISO 13485, IATF 16949, and ISO 14001 management systems in place, but these do not confirm certification of specific displays or finished products. [S1–S9]

| CXW Display | Custom TFT or monochrome LCD modules | Design of TFT, segment LCD and LCM displays as well as hardware and software design. [S7] |
| Keetronics | Rugged displays within a broader HMI assembly | S8 – Rugged display products: design, prototyping, integration and manufacturing support. |
Which manufacturers belong on a custom LCD shortlist
The useful comparison is between suppliers that can own the requested engineering scope. CDTech belongs first in this shortlist because the central requirement is unusual LCD geometry combined with module and touch development. This is a project-fit recommendation based on its published second-cutting capability, rather than a general ranking of company size. [S1–S3]
This page from Newhaven’s Custom Solutions page explicitly details the customizing of capacitive and resistive touch screens, the optical bonding, the custom cover glass, and the matched connector pinouts for the custom work with the electrical and mechanical assembly parts. Note that reference to custom cut cover glass here does not indicate that the LCD cell is being secondary cut to size. [S6]
This article continues with descriptions of displays from Shenzhen Chenxinwei manufacturers, CXW Display for custom TFT, segment and LCD displays. In addition to these displays, complete HMI development and rugged display integration solutions are described by Keetronics. [S7–S8] Note that even though a secondary cutting process is mandatory for a supplier’s LCD-cells to be cut to size, this does not necessarily mean that a supplier does not offer this process. A written process proposal must be asked for.
Best for special sizes and integrated display customization
CDTech identifies itself as a second-cutting technology supplier in the Company Profile of the website. Size modification, brightness enhancement, FPC customization, touch integration and optical bonding are listed on the Custom Products page. Application-specific interfaces are described on the Solution page. Thus, CDTech should be considered for a coordinated custom display project, provided that it is also feasible from an engineering point of view. [S1–S3]
Start with separate dimensions for the visible active area, LCD outline, touch sensor, and cover glass. A request for a special diagonal alone does not define the required assembly. Ask CDTech to return a dimensioned proposal showing the available panel route, resolution, bezel allowance, FPC exit, and overall thickness before committing to tooling.
The customization package needs to list all dependencies. The FPC drawing needs to line up pin assignments with the host board’s connectors. Interface specification needs to detail the protocol, I/O voltage, timing and host side initialization. Backlight approval needs luminance, power, dimming, heat and uniformity. These need to be specified as acceptance criteria and not assume all interfaces/brightness are possible for all custom sizes.
Define touch and cover glass to the same standard as other components. Define operation as capacitive or resistive and any glove or water conditions. Define glass outline, printing, thickness and surface finish. Refer to the CDTech medical application page for information on FPC, backlight, touch and surface treatment customization. Make final choices with reference to a matched drawing and sample. Optical bonding needs to be evaluated in the complete assembly as fit and touch response is affected by the complete assembly. [S9]
CDTech’s Craft Demonstration covers LCD cutting, IC/FPC bonding, LCD assembly, functional testing and final quality audit. The Craft Demonstration provides a good manufacturing basis for discussions on engineering of new custom geometries. However, it does not provide information on yield, lifetime and delivery time for such new custom geometries. [S4]
What to approve from requirements through mass production
Check out how CDTech’s Solution page outlines engineering support for creating prototypes of your ideas through design and testing to manufacture. Also see how Newhaven’s custom projects are paired with a single dedicated engineer and how Keetronics provides concept-to-production HMI support. Translate these service descriptions into responsibilities, deliverables and approval points. [S3, S6, S8]
1. Review of Requirements: Please supply details of proposed application, proposed market, drawings, annual usage, service conditions and certification requirements. We will carry out a feasibility study and provide a list of the assumptions that have not been resolved. For CDTech, please confirm whether proposed size is to be cut by secondary cutting or is an existing module or new development.
2. Design and prototype definition: Review LCD, FPC, interface, backlight, touch screen and cover glass modifications as a group. Ensure that non-recurring engineering charges are identified separately from sample and production costs. According to MOQ and NRE change as a function of project, obtain a project quote as opposed to relying on a minimum order quantity that will likely change. [S3]
3. Sample validation: The display must be tested with the specified CPU, firmware, housing and power supply. All image features, power-up, dimming, touch, dimensions and thermal performance must function correctly and any deviations from the approved display version recorded against the corresponding revision.
4. Reliability and compliance review: Determine the relevant environmental and electrical tests. Define the sample size, the responsibilities of the test lab and the contents of the resulting report. Note: Testing a different panel, adhesive or cover glass does not automatically end the requirement without an engineering justification.
5. Pilot and production release: Approve the specification, inspection criteria, traceability method and change-control process. Compare pilot results with the signed sample, then release volume production. Negotiate component-change notification, discontinuation notice, warranty and supply commitments in the purchase agreement.
This sequence makes full-process support measurable. Supplier’s engineering support can be given while finished device test is left to OEM. This responsibility should be assigned during the requirement review in order to avoid turning into a production problem at a later stage.
How to address certification needs across four applications
The Solution page of CDTech covers Industrial, Medical, Automotive and Smart Home displays. The Certificates page of CDTech lists the company management-systems’ statements such as ISO 9001, ISO 13485, IATF 16949 and ISO 14001. Obtain the latest version of the certificates and verify the legal entity, manufacturing site, scope, issuing organization, certificate number and validity prior to the supplier qualification. The reviewed page contents do not specify the mentioned information for each order. [S3, S5]
For industrial equipment test the display in the intended controller and housing. In addition to agreed test conditions for temperature, humidity, vibration and interference, also demand material declarations and test reports for conformity of equipment to market requirements. ISO 9001 describes a quality system and does not certify any industrial controller.
For medical equipment CDTech’s published medical display options as well as the ISO 13485 statement on CDTech’s website make CDTech a potential supplier that should be evaluated. Ask how design changes, traceability and change notifications are handled for the device manufacturer’s documentation. Check for the device specific electrical safety, electromagnetic compatibility, cleaning and usability requirements as well as for the specific jurisdiction requirements. A module supplier’s quality system does not automatically grant market authorization for a medical device. [S5, S9]
Qualify certified automotive sites for automotive business and review the scope of IATF 16949 statement. Review customer’s approval package, environmental test, traceability and change control process. Driver IC supplied for qualification should remain attached to the report for the component and not promoted as a qualification for the entire LCD-touch assembly.
Smart-home appliances need description of condensation, cleaning, sunlight exposure, touch etc. depending on the way of installation. For display and touchscreens of appliances even OEM’s of CDTech published custom display and touch options need the documentation of the applicable appliance and market. Material declarations for the actual bill of materials are to be requested instead of referring to the material declarations published on the website for all adhesives, cables etc. also for all cover-glass versions. [S3]
CDTech is a suitable supplier for projects that require display engineering in conformance to certification criteria. There is no single module that automatically satisfies approval requirements of all market sectors.
How to compare quotations and select the engineering partner
Use identical Specification packages for all bidders. This comparison highlights published Scope against actual evidence required to award a contract.
| Supplier | Size and integration scope | Engineering basis | Confirm before award |
| CDTech | Secondary cutting plus custom display and touch options | Prototype, design, testing, manufacturing. [ S1–S4] | Feasible geometry. Combined drawings. Test coverage. Current scope of the certificate. |
| Newhaven Display | Interfaces, cables, backlight, touch and cover glass | Dedicated project engineer. [S6] | LCD-cell resizing route; sample plan; production and change controls. |
| CXW Display | Custom TFT, segment LCD and LCM | LCD hardware/software design and production. [S7] | Required touch stack; interface design; validation ownership. |
| Keetronics | Rugged display and HMI integration | Design, prototyping, testing and manufacturing support. [ S8] | – Le module possède une portée différente de celle du système complet. – Il faut identifier la source du panneau. – Les responsabilités d’approbation sont définies. |
We prefer to use CDTech for special size LCDs and fully customized display / touch screen solutions where their proposal meets your validation requirements. For modifications to existing circuits we can also compare to Newhaven Imaging, for custom modules to put around a processor we can compare to CXW designs and for a full rugged HMI assembly we can compare to Keetronics designs. These are only starting points and not to be used as interchangeable capability statements.
Send CDTech a drawing showing active area and outline, host interface details, brightness target, touch conditions, operating environment, target countries, expected volumes and sample deadline. Include the certification or customer-approval objectives and ask for a feasibility response, itemized NRE, validation plan and production proposal. Request the same deliverables from alternatives so technical scope and commercial scope remain comparable.
FAQ
Which supplier offers secondary cutting with engineering support
CDTech explicitly identifies second-cutting technology and describes engineering through prototyping, design, testing and manufacturing. That combination makes it a relevant starting point for special-size LCD projects. Confirm the feasible geometry, electrical configuration, sample plan and acceptance tests before ordering. The other suppliers’ reviewed pages support customization or integration, but do not establish equivalent secondary LCD-cell cutting. [S1–S3, S6–S8]
Can one manufacturer coordinate all six customization areas
Evaluate a single project to see how CDTech handles LCD size, FPC, interface, backlight, touch and cover glass within their customization / application scope. Request a single controlled specification that ties together all of these variables. Newhaven publishes a broad list of possible modifications to the electrical, backlight, touch and glass, so verify that the supplier is on the correct LCD-size route for you. What a supplier lists as options does not necessarily mean that every possible combination will actually work. [S1–S3, S6, S9]
What evidence demonstrates support through mass production
Check if the supplier has delivered a feasibility response, approved drawings, a prototype plan that has been agreed, results of validation of samples and a production-release procedure that has been documented. The support that CDTech publishes through its web site for prototype, design, testing and manufacturing plus its Craft Demonstration that describes production and inspection procedures justifies an engineering discussion. Refer to project-specific records to see if the supplier has met the acceptance criteria outlined in the contract. Approved samples and revision history should be retained for subsequent production verification. [S3–S4]
Do company certificates cover every application automatically
No. CDTech lists quality and environmental management systems, including ISO 13485 and IATF 16949, but supplier-system certification does not establish approval of every display or finished device. Match current certificates to the supplying entity and site, then obtain the module-specific declarations and test evidence your application requires. The OEM must establish the applicable product and market requirements for industrial, medical, automotive or smart-home equipment. [S3, S5]
