Innolux AT043TN25 V.2 4.3 Inch 480×272 RGB / TTL TFT LCD Panel

Innolux AT043TN25 V.2 4.3 Inch WQVGA RGB TTL Panel for Compact Equipment

Innolux AT043TN25 V.2 is a 4.3 inch WQVGA TFT LCD panel for compact industrial devices and replacement sourcing. The public table confirms 480×272 resolution, 500 cd/m² typical brightness, parallel RGB 1-channel 8-bit interface with 40-pin FPC, 105.5×67.2×3.1 mm outline, 89/89/89/89 viewing angle, 1000:1 typical contrast ratio, 8S1P WLED backlight rated 20K hours without driver, TN normally white transmissive work mode, 16.7M colors, 50% NTSC, 0.57W total consumption and -20 to 70 °C operation. The public table also lists an active-area value that appears unusually large for a 4.3 inch panel, so the active-area/drawing should be confirmed in RFQ.

Confirmed Product Specifications

Compact Display Application

This panel can be used in small industrial controllers, portable equipment, test devices, access panels and replacement projects where 4.3 inch 480×272 RGB input is already defined. Its 500-nit brightness is useful for brighter indoor equipment.

Public Data to Confirm

The detailed table includes an active-area value that does not look consistent with a 4.3 inch panel. This update preserves the public table as found, but the RFQ should request the official drawing or datasheet before mechanical approval. Do not cut tooling from this page alone.

RGB TTL Host Matching

Confirm the 40-pin FPC pinout, timing, voltage, backlight pins and power sequence. A display with the same resolution can still fail if the host RGB mapping or FPC direction differs. Replacement buyers should provide photos of the existing panel label and connector.

No-Touch Scope

The attributes list no touch. If touch is needed, specify resistive or capacitive touch, controller, bonding, cover glass and ESD/grounding. Adding touch changes the stack and should be quoted as an assembly requirement.

Viewing and Contrast

The public table lists wide viewing and 1000:1 contrast, but the mode is still shown as TN normally white. Engineers should validate readability from the real operator angle and compare with any original panel in replacement projects.

Production Control

Lock model, revision, FPC, drawing, backlight scope and substitute approval rules. Small-panel substitutes can differ in outline, FPC exit and optical behavior even when catalog values match.

Handling the Active-Area Data Conflict

The active-area value shown on the public table appears inconsistent with a 4.3 inch panel. For procurement, this means the official drawing must be requested before mechanical approval. LCDind should confirm the actual active area, outline, FPC exit and viewing area from the datasheet or current stock label before the buyer cuts a bezel or orders a replacement batch.

No-Touch Replacement Scope

Unlike AT043TN24 V.7, this page is marked no touch. That makes it relevant for equipment controlled by buttons, encoders or a separate touch overlay. If the old device includes a touch layer, confirm whether the touch is separate from the LCD or whether this model is not the right replacement.

RGB Host Matching

A 40-pin parallel RGB panel must match the host timing and pinout. Provide controller schematic if available, original panel photos and FPC orientation. If the host software is fixed to 480×272, this panel can preserve the UI, but electrical matching still decides whether it works.

Quality and Inspection Notes

Small panels should be inspected for FPC damage, backlight uniformity, visible dust, pixel defects and polarizer marks. If the device has a front lens, inspect the sample after installation because pressure from the bezel can create display artifacts.

Drawing Confirmation Before Tooling

Before mechanical tooling or volume replacement, request the official Innolux drawing and compare it with the customer's front-window drawing. Confirm active area, outline, FPC exit, thickness, backlight pins and viewing area. Because the public active-area value appears unreliable, drawing confirmation is not optional for this product. It should be part of the RFQ response before any sample is approved for production.

Final Buyer Check

Before repeat purchase, confirm the official drawing and no-touch scope in writing, especially when replacing a panel from equipment that may use a separate touch layer.

RFQ Checklist

• Confirm official drawing, active area, outline, FPC direction, RGB timing and voltage.
• Define panel-only or touch/display assembly scope.
• Provide original panel photos, host controller and enclosure drawing for replacement work.
• State quantity, inspection criteria, packaging and substitute approval rules.

Engineering Review Note

The specifications above are taken from the current public product page and should be treated as selection inputs, not final system approval. Before sample purchase or production order, LCDind should review host interface, drawing, optical stack, touch requirement, controller-board scope, operating environment, supply quantity and inspection criteria. This update keeps the existing product URL unchanged while making the page more useful for B2B engineering and sourcing decisions.

Engineering FAQ

Is there a data point to confirm?

Yes. The active-area value should be checked against the official drawing.

Is touch included?

The public attributes list no touch.

What interface is listed?

Parallel RGB 1-channel 8-bit with 40-pin FPC.
