4.3 Inch TFT 480×272 RGB

4.3-Inch 480×272 RGB TFT LCD Module for OEM Equipment

This 4.3-inch TFT LCD module is a production-oriented RGB display for OEM equipment programs that need a standard-size industrial screen with known mechanical and electrical data. The confirmed configuration includes 480×272 resolution, RGB interface, 350-nit brightness, 6 o’clock viewing direction, no touch in the standard configuration, -20°C to +70°C operating temperature, -30°C to +80°C storage temperature, 105.5*67.2*3.0 mm outline, 95.04*53.86 mm active area, 500:1 contrast ratio, 3.3V supply, 20000-hour LED lifetime, and panel model 90-04304-001.

This module is best considered when the host board is designed to drive an RGB TFT directly. It is different from an HDMI kit or a full touch HMI assembly. The buyer is responsible for confirming timing, pinout, signal routing, software, cable path, and any touch or cover-lens requirement. That makes it suitable for equipment manufacturers with embedded hardware capability who need a repeatable display source rather than a consumer monitor.

Key Specifications

Application Fit

The module can be used in industrial HMI panels, medical devices, factory equipment, embedded controllers, smart terminals, test fixtures, and commercial equipment where a 4.3-inch landscape display is enough for basic operator feedback. The 480×272 resolution suits status pages, icon menus, setup screens, parameter values, and simple warnings. It is not intended for dense dashboards, high-resolution graphics, or complex multitasking interfaces.

The standard no-touch configuration fits products that use buttons, membrane keys, encoders, or external controls. If the project needs touch input, the touch stack should be reviewed separately because it affects optical performance, front-window design, controller electronics, cable routing, and assembly thickness. Do not assume touch from the diagonal size or product category.

RGB Interface Review

The RGB interface must be checked with the host processor before PCB release. Confirm pixel timing, synchronization, data format, voltage level, pin assignment, FPC direction, clock margin, and EMI behavior. RGB displays can work well in embedded products, but they need disciplined board layout and stable firmware. If the host controller has limited display resources or long cable routing, a controller-board solution may be easier to validate.

The 3.3V supply, 350-nit brightness, and 20000-hour LED lifetime should be reviewed with the product’s duty cycle. A display used occasionally on a service panel has different lifetime and thermal considerations from a screen that stays on continuously in a sealed enclosure. For long-running industrial products, backlight setting and internal temperature should be tested in the final housing.

Mechanical Planning

The outline dimension is 105.5*67.2*3.0 mm, and the active area is 95.04*53.86 mm. The front opening should match the active display area with enough overlap to hide non-viewable borders. Review gasket margin, bracket support, connector clearance, FPC bend radius, front lens, and service access before tooling. The 6 o’clock viewing direction should be checked against the actual mounting orientation and operator position.

Production Approval Checks

For production approval, the engineering team should test the display with the final RGB timing, cable length, enclosure opening, backlight setting, and operating orientation. Verify that text and symbols are readable from the expected operator angle and that the 6 o’clock viewing direction matches the installation. If the product uses a protective cover, evaluate reflection and brightness after the lens is installed. The approved sample should be tied to panel model 90-04304-001 and the exact drawing used for the enclosure.

Selection Boundaries

This RGB module is a good fit when the host board can drive the display directly and the UI remains within the limits of 480×272 resolution. It is a weaker fit when the product needs plug-and-play HDMI, advanced touch behavior, high-resolution graphics, or direct sunlight readability. Defining these boundaries before purchasing helps avoid substituting a different 4.3-inch display that matches only the diagonal size but not the interface, viewing direction, thickness, or lifecycle requirement.

Procurement and Customization

For OEM/ODM projects, provide the equipment type, host processor, RGB timing requirement, drawing, display opening, cable direction, input method, ambient-light condition, sample schedule, and forecast volume. LCDind can review brightness adjustment, cover glass, touch matching, optical bonding, FPC or cable change, packaging, and lifecycle requirements. If model 90-04304-001 is being used as a replacement, provide the current panel label and datasheet so the electrical and mechanical match can be confirmed.

Quality and Repeat Supply Notes

For repeat orders, define the approved model number, drawing revision, RGB timing, brightness level, viewing direction, and packaging expectation. If the buyer has incoming inspection requirements, provide them before mass production so LCDind can review whether they match normal factory testing. This reduces disagreement later over brightness tolerance, cosmetic criteria, or connector handling.

When replacing an older 4.3-inch display, compare more than resolution and outline. Confirm the active area, pin assignment, voltage, viewing direction, backlight current, temperature rating, and mounting stack. A substitute that fits the front opening may still fail if the RGB timing or FPC orientation is different. Send the existing datasheet and photos during RFQ for a more reliable match.

For approved replacement work, keep one controlled comparison sheet for engineering, purchasing, and quality teams.

Document approved tolerances clearly.

Keep this approval record attached to the drawing revision used for the enclosure and incoming inspection.

FAQ for 4.3-Inch RGB TFT Projects

Is this module ready for HDMI connection?
No. This page describes an RGB TFT module. If the host requires HDMI, select or request a controller-board or HDMI kit solution.

Does it include touch?
No. The standard configuration is no touch. Touch should be specified as a separate assembly requirement.

What should be checked before sample approval?
Confirm RGB timing, pinout, power, drawing, viewing direction, FPC route, brightness target, and operating environment.

What customization can be reviewed?
Common review items include brightness, FPC direction, cover glass, touch integration, optical bonding, packaging, and lifecycle support.
