### 12.1" — 1024 x 768 XGA, 4:3

0.24 mm pixel pitch (≈ 105.8 PPI) on a 245.76 x 184.32 mm active area.

### 289.47 x 222 x 26 mm

A 245.76 x 184.32 mm IPS active area inside that outline.

### One HDMI cable

Video in over a standard HDMI cable, touch out over USB.

## Overview

### 12.1" XGA HDMI touch display at 1400 cd/m², one part number

The 12.1" HDMI TFT Touch Display is a complete assembly: a 12.1-inch IPS panel at 1024 x 768, a projected-capacitive touch sensor behind 1.8 mm cover glass, and the driver board with the LED backlight driver on it. Video arrives over a standard HDMI cable, touch reports back over USB, and the module runs from a DC input.

At 1400 cd/m² (nits) it is rated High Brightness on our scale — nearly three times our 500 cd/m² comparison baseline — with a -30 ~ +80 (℃) operating window.

#### 245.76 x 184.32 mm behind 1.8 mm glass

The 4:3 panel gives 184.32 mm of vertical active area inside a 289.47 x 222 mm outline, and the IPS panel holds its colour and contrast when the screen is read from an angle.

The 1.8 mm cover glass overhangs the frame, giving a flat glass front face across the touch area.

### Why a module instead of a bare panel

Built up from parts, this display would be a panel, a signal harness, a matching driver board, a backlight driver, a touch sensor, a touch controller and a supply for all of it — each a separate part number, a separate supplier and a separate qualification. Here they are one assembly.

- One video cable. Standard HDMI in to a 1024 x 768 panel.

- Touch already fitted. The projected-capacitive sensor sits behind 1.8 mm cover glass and reports over USB — no separate controller board to mount and wire.

- Backlight driver included. The LED driver is part of the module, and the panel cable is fitted at the factory.

- One assembly to qualify. Panel, touch, driver board and backlight driver ship under one part number, from one supplier, with one revision history.

### Assembled and tested before shipment

Touch sensor and cover glass fitted, driver board mounted, panel and touch cables dressed, and every module functionally tested before it ships.

The board is part of the module part number, so panel, touch and board revisions move together under a single change-notification process.

### Where it is used

| Application | What this module brings to it |
| --- | --- |
| Machine HMI and operator panels | 1400 cd/m² and PCAP touch on a standard HDMI source |
| Self-service kiosks and vending front panels | 1400 cd/m² behind glass on a public-facing front panel |
| Industrial weighing and process terminals | A 4:3 read-out with direct on-screen entry |
| Test and measurement equipment | A bright XGA screen operated on the glass |
| Access control and building panels | A 12.1" touch front end driven from a standard HDMI source |
| Unheated plant and machine rooms | A -30 ~ +80 (℃) operating range |

| PCAP USB cable | 315-U084B12500 | 500 mm / 19.69 inch |

### Customisation services

This module can be adapted, or swapped for a closer fit from the range. We hold over 500 standard models from 3.5" to 21.5", and we adapt them — or design something new — around the enclosure and the environment you already have.

| Level | What we change | When it fits |
| --- | --- | --- |
| Adapt this module | Cover glass thickness, shape and printing, surface treatment, optical bonding, touch tuning for gloves and water, backlight brightness, cable lengths and connector types, mounting pattern, branding and packaging | The 12.1" panel and the HDMI interface suit the design, and the fit to the enclosure needs adjusting |
| Re-specify from our range | A different size, resolution, brightness or interface — HDMI, USB-C, LVDS, MIPI, TTL — from the 500+ models we already stock and support | A neighbouring size, resolution, brightness or interface suits the design better |
| Design to your requirement | Custom driver board, custom mechanical, panel sourcing and long-term supply planning for your programme | The design calls for something outside the standard range, or has to stay in production for many years |

An early idea is enough to start from — we can look at a requirement and come back with feasibility, cost and lead time.

Whatever we agree — brightness, temperature range, mechanical envelope, cover glass, touch behaviour — is written down before anything is built, so the sample you approve is what later batches are made and inspected against.
