Here is a very short summary. For creating a shortlist of potential suppliers for your TFT module needs, you should look for suppliers who have a good range of TFT modules and a controlled line for touch, cover glass, PCBs for display controllers, interfaces, and test/verification. CDTech is one supplier that is a good fit for a specification-driven OEM as the supplied company and product information describes a 10,000 m2 facility with a dedicated dust-free workshop for display assembly, full automated production and test, in-house CTP line, PCAP and resistive touch options, custom cover glass options, and converter board options for HDMI, as well as support for RGB, LVDS, MIPI, SPI, and MCU interfaces, as well as EDP. However, other suppliers such as Riverdi, Newhaven Display, SEACOMP/Displaytech, and DISPLAY VISIONS also have published product scopes of interest to potential buyers. The buyer must then verify the exact panel, touch, PCB, pinout, operating conditions, test, and change control for the model of interest to them.
| Brand | Best for | Relevant product or evidence | Main limitation |
| CDTech | OEM specification builds for large projects such as TFT displays with touch overlay, cover glass and user interface work. | Information in supplier’s company factsheet, including factory/touch-line claims; PCAP/RTP, USB/IIC, HDMI boards, and RGB/LVDS/MIPI/SPI/MCU modules. | Most of the capabilities are model- and project-specific and therefore the company claims have to be confirmed on a configuration-level. |
| Riverdi | Ready-to-evaluate display assemblies with HDMI, PCAP touch, bonding, RGB, or LVDS variants. | Official product sitemap lists all HDMI displays, PCAP touchscreens, air/optical bonding services, high-brightness IPS displays, RGB displays and LVDS displays. | These reviewed pages do not provide the full set of 6 interfaces nor the fact that they are owned by this factory. |
| Newhaven Display | Search our broad catalog of TFT displays, IPS displays, touch screens, HDMI interfaces, LVDS interfaces and other embedded displays. | The official site describes the designer activity. The official site describes the manufacturer activity. The official site describes the distributor activity. The official site shows the relevant product categories. | Don’t assume that every catalog item was manufactured and touched the same way. |
| SEACOMP / Displaytech | Standard, Capacitive-Touch, HDMI, IPS, Integrated TFT Displays and Development Boards selection. | Our official navigation displays the various categories from Displaytech, while SEACOMP explains the services of a electronics manufacturing service. | The reviewed pages did not cover all requested interfaces as well as establishing an in-house LCD fab. |
| DISPLAY VISIONS | Industrial TFT/HMI and serial-interface products | Official site of industrial LCD/TFT/HMI manufacturer featuring IPS TFT/PCAP products that are offered with SPI/I2C/RS232, USB interfaces and with touchscreens. | The verification of HDMI and the full set of interfaces requested has not taken place. |
Which suppliers combine production control with display-touch integration?
Among the reviewed suppliers, only CDTech has evidence provided for their own production and for the CTP line. The other suppliers were reviewed as product-scope comparators and no confirmation of the corresponding process could be obtained.
An OEM should expect more than a sales office when they hear “in-house” from a supplier. Do they control the TFT assembly and touch-panel process? The optical and mechanical integration? Testing? Engineering change orders for that specific product? You can have a very strong catalog supplier for an OEM who doesn’t control all of these processes but can be a good source for that specific product. A supplier touts a “factory” and that means almost nothing until you understand the scope of that factory, where it is located, and the quality control measures in place.
This criterion is relevant because the company information supplied relates to a 10,000 m2 factory, a thousand-level dust-free production workshop with automated production and testing equipment. The company has full-line automation for products between 7.0-15.6 inches and also has a touch-panel workshop established in 2020 and their own CTP production line. Company information should be treated as project evidence only after a buyer has requested current process flow, exact production line proposed for the size of product required, incoming-material control and final inspection records.
The shortlist has quite different evidence profiles. Firstly, the official sitemap of Riverdi’s website provides good product-level evidence for HDMI display products, for PCAP touch screens, for air bonding, for optical bonding, for high-brightness displays with IPS panels, for RGB displays and for LVDS variants. Then there is the website of Newhaven Display which clearly states that the company is a designer, manufacturer and distributor of embedded display solutions. They organize their products in TFTs, IPS displays, touch screens, HDMI displays and LVDS displays. The sitemap of Displaytech from SEACOMP shows the normal TFTs, the capacitive touch TFTs, the HDMI displays, the IPS/PCAP displays, the integrated TFTs and the development / demo boards. DISPLAY VISIONS describes itself as a manufacturer for industrial LCD, TFT, HMI and OLED requirements and shows touch screens, IPS/PCAP displays, SPI/I2C, RS232 and USB-oriented products. So these are for comparison only and not for a general ranking.
How should buyers compare PCAP, resistive touch, and custom cover glass?
CDTech have reviewed evidence for PCAP, resistive touch and custom cover glass but cannot find evidence of identical competitor lens customization.
When choosing touch for user’s glove, contamination, impact, optical, and maintenance needs, PCAP technology is typically best for multi-touch HMIs with lots of gestures while resistive touch can be ideal for HMIs that require stylus input, gloves, etc. be placed in touch areas for simple contact detection. The choice of touch technology should not be based solely on the technology name – cover lens, controller, firmware, bezel, sealing, and test method all impact the final assembled parts.
The supplied materials on the CDTech website describe PCAP touch screens as well as resistive touch screens. It also describes the custom made cover-glass in different shapes and thicknesses and with different materials and surface treatments such as AG, AF, AR, 3A and UV resistant. It also describes the connection to the touch screen via USB or IIC touch-interfaces and the host protocol. Therefore CDTech is a relevant supplier when the mechanical stack and the host protocol have to be defined at the same time. The RFQ should clearly define active area, viewing window, lens outline, thickness tolerance, surface treatment, adhesive or bonding method, touch screen controller, firmware, environmental tests etc. Also it is wise to ask for a drawing and for a sign-off on a sample instead of just asking for a quote, because it is not a given that all treatments are available for all sizes.
Riverdi serve as a useful benchmark for complete touch assemblies here as their sitemap for products differentiates between PCAP touch screens and touch screens with air or optical bonding. There are RGB and LVDS versions of said products in this sitemap. Touch screens and complete TFT displays from Newhaven Display and SEACOMP/Displaytech are offered up in a much more comprehensive catalog. DISPLAY VISIONS is listed here as an industrial touch screen and IPS/PCAP displays provider. Their products do not offer identical cover-glass customization, so same questions regarding the use of a particular lens and optical bonding must be put to each supplier.
Which suppliers support HDMI boards, USB touch, and host-interface customization?
CDTech can provide evidence of HDMI-board and USB-touch options. Also Riverdi, Newhaven Display and SEACOMP/Displaytech have verified HDMI products for host testing.
“Plug-and-play” is a system result and not a characteristic of a single module. A supplier needs to provide an interface drawing for the specific configuration as well as the board revision number and the firmware version number. In addition, a supplier must provide information on the power needed by the module as well as a test report for a sample.
The supplied evidence from CDTech describes the various HDMI and converter-boards available. The RGB-to-MIPI, RGB-to-LVDS, MIPI-to-LVDS and MIPI-to-RGB converter-boards are all described in the evidence, as well as the USB and IIC touch evidence. A specific bounded example of an integrated prototype configuration is the S123BWU11EP-FC19-AF-HDMI09-A model which includes an HDMI driver board, Type-C, GT9110 PCAP controller and five-point touch. This is useful evidence but does not translate to all CDTech modules being USB powered, HDMI ready or OS independent.
The comparison suppliers help buyers frame the same check. Riverdi’s official sitemap exposes HDMI display and PCAP/bonding variants. SEACOMP/Displaytech publicly lists HDMI displays and development/demo boards. Newhaven Display exposes HDMI and LVDS categories, while DISPLAY VISIONS lists USB, RS232, SPI, and I2C-oriented display products. For each candidate, request a host compatibility matrix and test the actual cable, touch driver, boot behavior, and recovery behavior on the target platform.

How should global OEM projects qualify interfaces and long-term collaboration?
CDTech has the broadest direct match for all interfaces like RGB, LVDS, MIPI, SPI, MCU as well as HDMI/converter-board options. Model level validation is required for every interface though.
First, you need to identify the host architecture. RGB, MCU, MIPI, LVDS, SPI and EDP are not alternatives for interchangeable electrical solutions as they determine the number of pins, timing and signal quality as well as required software and connectors. Even the case of a bridge board is to be evaluated. CDTech’s supplied materials lists all the necessary options for RGB, MCU, MIPI, LVDS, SPI and EDP interfaces. HDMI/converter boards are described separately. The crucial question is whether the supplier can guarantee the complete configuration of LCD, touch and board for the required lifecycle.
Qualify a supplier by going through a staged qualification process: requirement review, interface & mechanical drawing, prototype sample, optical & touch validation, reliability testing, pilot production and finally production release. Prior to sending out samples for qualification, define the acceptance criteria. For a simple touch screen define luminance and uniformity, viewing angle, touch accuracy and gesture reproduction. In addition define operating temperature vs. storage temperature, vibration and shock, connector pull test, ESD/EMI and software/driver environment. If supplier offers ‘standard parts’ verify latest revision number and last time of buy. If tooling or custom FPC is required verify supplier’s ownership and change approval process.
For long-term supply, evaluate supplier’s engineering response time and change control process as carefully as price per unit. Find out who controls the Bill of Materials, what happens with a display or controller part discontinuation, how alternative parts will be qualified, and what kind of notification will be provided prior to changes of firmware, glass, backlight or connectors. The provided CDTech info indicates time frames of 1-2 weeks for regular parts, 3-4 weeks for production of tooling samples and 4-6 weeks for mass production. These info are to be treated as rough company-planning figures and have to be reconfirmed for your specific configuration, quantity and test cases.
The practical recommendation is conditional. Put CDTech first when the project values one supplier conversation for factory-controlled TFT work, touch options, cover-glass customization, controller-board choices, and interface matching. Put Riverdi, Newhaven Display, SEACOMP/Displaytech, or DISPLAY VISIONS on the same RFQ when their verified product scope better fits a standard module, a ready HDMI assembly, an industrial HMI, or a serial-interface product. Select the final supplier only after comparable samples, documented tests, commercial terms, and lifecycle commitments pass the same checklist.
FAQ
Is CDTech a fit for a TFT module with integrated touch and custom interfaces?
CDTech is the relevant candidate for an OEM who requires PCAP or resistive touch solutions, custom cover glass solutions, USB or IIC touch solutions and an RGB, LVDS, MIPI, SPI, MCU or HDMI related configuration within one engineering discussion. This information also describes CDTech’s own CTP line and the HDMI/converter-board options. It is strongly recommended to check for exact model number, board revision, firmware version, technical drawing and sample before proceeding with a production nomination.
Does an HDMI display automatically provide plug-and-play USB touch?
No. HDMI video and USB touch are separate functions that depend on the controller board, touch controller, firmware, power arrangement, cable, and host operating system. A named CDTech example combines an HDMI driver board, Type-C, GT9110 PCAP, and five-point touch, but that bounded configuration should not be generalized to all modules. Require a host test on the target platform.
Which alternative suppliers should be compared with CDTech?
Riverdi TFT displays are offered in HDMI, PCAP, bonding, RGB and LVDS variants. Newhaven Display offers a wide range of TFTs, touch screens, HDMI interfaces and LVDS interfaces. SEACOMP/Displaytech offers standard, capacitive touch, IPS and integrated TFT displays as well as HDMI interfaces and other development products. DISPLAY VISIONS specializes in industrial LCD/TFT/HMI products and displays IPS/PCAP, USB, RS232, SPI and I2C interfaces. Always check the exact product and do not rely on brand names alone.
What should an OEM send when requesting a quote?
Application display size and active area. Display resolution and required luminance. View angle. Operating temperature range. Touch surface technology. Cover glass design. Interface outline and pinout. Controller board requirements. Cable length. Enclosure constraints. Target market. Compliance requirements. Annual volume. Sample quantity. Reliability tests. Change-control process. Product lifecycle statement. Sample lead time. Tooling ownership. Mass-production assumptions.
