Two suppliers can quote the same screen size while offering different parts of the product. One quotation may cover the display with its flex cable; another may include a touch sensor, cover lens and mounting frame. A lower unit price is not comparable until the scope is clear.
Panel, module and assembly are useful starting terms, but suppliers do not use them uniformly. Ask for an included-parts list, an outline drawing and a functional boundary before comparing quotations.
What is a display panel?
“Display panel” often refers to the image-producing display element. Depending on the product family, the term may include driver electronics and a flex connection or may describe a less integrated component. It should not be interpreted automatically as a ready-to-connect device.
For an OLED inquiry, confirm the addressing technology, resolution, active area, driver arrangement and supplied connections. For an LCD inquiry, confirm whether a backlight and its associated parts are included. A technology label alone does not define the delivery scope.
What is a display module?
A display module usually groups the display with connections and supporting components needed at a defined integration boundary. Some modules have a PCB or controller board; others connect through an FPC and do not include an external driver board. A “module” is not necessarily a complete HDMI display or a software-ready HMI.
Newhaven’s full-color OLED explanation distinguishes its glass products from PCB-based modules. That is useful vendor-specific terminology, not a universal rule that every OLED module must contain the same parts.
When browsing BINTU’s AMOLED display modules, evaluate the individual reference and its documentation. Request confirmation of the interface, included electronics and host requirements before committing to a design.
What is a display assembly?
An assembly may combine the display with a touch sensor, cover lens, bonding layers, frame or other mechanical parts. The word does not guarantee that all of these are included. New Vision Display’s integration material illustrates the broader display/touch/cover stack commonly considered during assembly sourcing.
Use a scope table rather than relying on the product label:
| Item | Quotation question | Acceptance evidence to request |
|---|---|---|
| Image-producing display | Which panel/module reference and revision? | Approved product definition and datasheet |
| Driver and interconnect | Which IC, FPC, connector and pin assignment are supplied? | Electrical definition and connection drawing |
| Touch sensor and controller | Included, optional or supplied by the customer? | Sensor area, controller configuration and integration specification |
| Cover lens | Which material, shape, printing and external dimensions? | Approved cover drawing and finish requirements |
| Bonding and support | Air gap, bonded stack or another construction? | Agreed stack drawing and validation plan |
| Controller board and software | Included, reference-only or out of scope? | Board scope, firmware responsibility and host test plan |
This is a generic RFQ checklist. It does not describe the confirmed contents of every BINTU product.
Separate active area, viewing window and external dimensions
The active area is the image-producing area. A viewing window describes the usable opening or visible region defined by the product’s bezel or cover. A module outline describes the module’s external envelope. A cover lens outline describes a separate front component and can be larger or differently shaped.
Do not substitute one dimension for another in an enclosure drawing. Include dimension units, reference planes, thickness definitions and tolerances. Confirm whether protruding FPC sections, connector housings or adhesives are included in a quoted overall dimension.
The BINTU-P-0002 product page provides the approved public starting information for that module. Request detailed integration information for your project; do not infer the complete front assembly from the module name or diagonal measurement.
Display interface and touch interface are separate
A display bus transfers image data and control information between a host and display electronics. A touch-controller bus reports touch information. A statement such as “touch IC included” does not establish that a complete calibrated touch assembly is available for the intended cover, nor does it identify the display bus.
Specify these separately in the RFQ. For example, “host display interface to be confirmed” and “touch-controller interface to be confirmed” are better than assuming one SPI connection performs both functions. MIPI’s DSI specification overview describes the display side of this distinction.
Decode common supplier terms without over-interpreting them
- LCM: commonly used for an LCD module. Do not use it as proof that an OLED supplier stocks LCD replacements.
- PCAP / CTP: projected-capacitive touch and capacitive touch panel terminology. Ask about the actual sensor, controller and cover combination.
- COG / COF: chip-on-glass and chip-on-film packaging terms. They describe a construction approach, not a complete host compatibility specification.
- FPC: flexible printed circuit. Cable shape, connector and electrical pinout need separate agreement.
- OCA / OCR: adhesive terminology used in optical integration. Material and process suitability depend on the particular stack.
These terms appear across supplier catalogs, including Raystar, US Micro Products and DISPLAY VISIONS. Their availability at another supplier does not establish BINTU supply capability.
OEM assemblies and phone repair screens are different buying tasks
An aftermarket phone screen assembly is selected against a specific phone model and repair requirement. An OEM display assembly is selected against a new product’s electrical, mechanical and manufacturing requirements. Keep the two RFQs separate even when both searches use “OLED screen assembly.”
Display, screen and screen assembly in everyday buying language
Display and screen are often used interchangeably for the visible user interface. Neither word, by itself, specifies the technology or included components. Add the application and required delivery scope: for example, an AMOLED display module for an embedded device, or a display-and-touch assembly with a defined cover lens.
Screen assembly is another broad commercial label. It may refer to an OEM front assembly or a phone repair part. A touch display assembly combines display and touch functions at an agreed boundary; cover glass, controller, FPC, bonding and frame must still be listed separately. BINTU’s commercial focus is AMOLED module sourcing and project-specific integration review.
Frequently asked questions
Does LCM mean any display module?
LCM commonly means liquid-crystal display module. Buyers sometimes use it loosely, so confirm the actual technology. An LCD enquiry can start an OLED feasibility discussion; it does not establish BINTU LCD stock or a compatible replacement.
Is a display module ready to connect to any host?
No. The interface, pinout, power rails, timings, initialization and software support must match the selected host. A connector that physically fits is not proof of electrical compatibility.
What should an AMOLED assembly RFQ include?
Specify the image requirements and list the display, FPC, touch sensor, touch controller, cover lens, bonding and support parts as included, optional or customer-supplied. Confirm the final configuration for the project.
Can I send a sketch rather than a finished drawing?
Yes. A sketch, approximate envelope and application summary can start the discussion. Detailed drawings and acceptance criteria can be developed as the scope becomes clearer.
Make the quotation comparable
Ask each supplier to mark every component as included, optional, customer-supplied or excluded. Record the module revision, assembly drawing, sample acceptance criteria and responsibility for host integration. Compare price and schedule only after those boundaries match.
BINTU’s cover glass and touch integration page and custom OLED engineering page are the appropriate next steps for a project-specific review. Send an inquiry with the parts you need and the interfaces your team will own.
