Displays & touch
China Worx specifies, sources and integrates touch displays for industrial and commercial products: touch monitors, open frame displays, panel PCs, sunlight-readable and outdoor screens, and custom display assemblies. Shenzhen and the Pearl River Delta are one of the world's largest centres for display modules and touch panels, and we work with those factories directly, on projects from a 10.1-inch machine HMI to 65-inch outdoor signage.
Most display projects start from a standard product and end with one that has been adapted: a different cover glass, a brighter backlight, a bonded touch sensor, a sealed front, a longer cable. We cover the full range, from catalogue monitors to fully custom builds.
Housed touch monitors in aluminium or rubber-edged frames for desks, walls, machines and VESA mounts.
Open frame monitors and front-mount kits for integration into your own enclosure, kiosk or machine panel.
Touch PCs on ARM/Android or Intel/Windows platforms, from industrial tablets to fanless industrial PCs.
Sunlight-readable displays for shop windows, vehicles and outdoor use, typically from 1,000 nits upwards.
IP65 front-sealed and IP69K washdown-rated monitors and PCs for outdoor, food and process environments.
Transparent OLED and Micro-LED for showcases, cooler doors and lightbox installations.
Digital signage, interactive kiosks, interactive whiteboards, stretched bar displays and USB-C portable screens.
PCAP and resistive touch sensors, cover glass, front kits and back kits for your own display build.
TFT and IPS LCD modules, including drop-in replacements for discontinued panels.
Projected capacitive touch (PCAP) is the default for most new products because it feels like a smartphone and sits behind solid glass. Resistive touch is older but still the right answer in some places, especially where operators wear heavy gloves or the screen is regularly wet.
| Projected capacitive (PCAP) | Resistive | |
|---|---|---|
| How it works | A sensor grid behind the cover glass detects the change in capacitance from a finger. | Two conductive layers make contact when pressed. |
| Multi-touch | Yes, typically up to 10 points | Usually single touch |
| Gloves and styluses | Works with thin gloves; thicker gloves need tuned controller firmware and testing | Works with any glove or stylus |
| Water and dirt | Water rejection available with tuned firmware | Largely unaffected by water films |
| Surface | Glass, scratch resistant, can be optically bonded | Flexible top film, more sensitive to scratches |
| Typical use | Kiosks, HMI panels, medical devices, signage, point of sale | Heavy industry, legacy systems, cost-sensitive panels |
In a standard display a thin air gap sits between the LCD and the cover glass or touch sensor. Light reflects at every glass-to-air boundary, which washes out the image in bright surroundings. Optical bonding fills that gap with an optically clear adhesive, either a liquid (LOCA) or a film (OCA), so the stack behaves optically as one piece.
| Air gap | Optically bonded | |
|---|---|---|
| Reflections | Internal reflections at each glass-to-air surface | Internal reflections largely removed |
| Readability in daylight | Lower contrast in bright light | Noticeably higher contrast |
| Condensation | The air gap can fog during temperature swings | No air gap to fog |
| Impact | Cover glass breaks independently | Bonded stack is more robust and holds fragments together |
| Rework and cost | Easy to separate and repair, lower cost | Difficult to rework, so process yield matters; higher cost |
Bonding quality depends on the process as much as the material. Dust trapped in the adhesive, bubbles or uneven curing show up as permanent defects, which is why we qualify the bonding line and its cleanroom, not only the datasheet of the finished display.
Most display specifications start with brightness, measured in nits (cd/m²). The table below shows typical starting points; the right figure depends on viewing angle, glass treatment and how much heat the enclosure can carry away.
| Environment | Typical brightness | Sealing | Points to watch |
|---|---|---|---|
| Office, control room, lab | 250 to 400 nits | None or front IP54 | Standard panels, matte or anti-glare surface |
| Shop window, vehicle cab, semi-outdoor | 700 to 1,500 nits | IP65 front | Anti-reflective glass and optical bonding |
| Direct sunlight | 1,500 to 3,000 nits and above | IP65 enclosure | Thermal management, wide-temperature panel, bonding |
| Food, pharma, washdown | Application dependent | IP69K | Stainless housing, sealed connectors, resistance to cleaning agents |
IP65 means dust-tight and protected against water jets. IP69K adds protection against high-pressure, high-temperature washdown, the standard for food processing and other hygienic environments.
Brightness alone does not make a display readable outdoors. Anti-reflective glass and optical bonding often improve readability more than extra nits, and every additional nit adds heat that the enclosure has to remove. We look at all three together before choosing a panel.
Glass & integration
Chemically strengthened glass in the thickness your impact rating needs, with printed borders, logos, IR windows and cut-outs for buttons or sensors.
Anti-glare (AG) etching diffuses reflections, anti-reflective (AR) coating reduces them, and anti-fingerprint (AF) coating keeps the surface easy to clean. We combine them to suit the environment.
Controller firmware tuned for gloves, water, thick cover glass and electrical noise from your machine. This is tested on your hardware, not only on the supplier's bench.
HDMI, DisplayPort and USB-C for monitors; LVDS, eDP and MIPI DSI for embedded panels; USB or I²C for touch. We match connector, cable length and pinout to your electronics.
ARM-based boards with Android or Linux for dedicated devices, Intel-based PCs with Windows for industrial software, with Wi-Fi, Ethernet, serial and fieldbus options as needed.
VESA mounts, panel mount with front sealing, open frame for integration, and custom brackets and housings for your enclosure.
Display panels change faster than most of the products they go into. When a panel is discontinued, finding one with the same diagonal is the easy part. A replacement also has to match the electrical interface and timing, the backlight driver, the mechanical outline and mounting points, the brightness and colour, and the touch controller behaviour your software expects.
We check each of these against your existing design before recommending a replacement, and where no drop-in part exists, we design the adapter board, bracket or firmware change that makes a close match fit. This connects directly to our component procurement work, and the same approach is described in our guide to end-of-life components.

Insights
When a part goes EOL, you have more options than a last-time buy. Authorised stock, franchised excess, re-engineering and qualified alternates.
