Em ambientes de trabalho agressivos, como eletrodomésticos de cozinha gordurosos, operação noturna cega, e condução de veículos, traditional button panels and ordinary LCD screens often suffer from false touches, poor readability, and failure due to freezing under low temperatures. Além disso, non-square display modules have limited adaptability for round holes and narrow-bezel structures, resulting in long procurement and debugging cycles.
Shenzhen NISINOPTO Co., Ltda. (NISINOPTUS) presents a one-stop supply solution for the 1.47-inch square AMOLED touch display. Centered on square viewing area, touch interaction and wide-temperature performance, we provide full support from structural adaptation, system board integration to mass delivery. For samples and quotation, please contact Ms. Lin: +86 13418565705, Site: https://www.sznisin.com.cn/
Principais recursos do produto
- Square Display Area & Alta resolução Adopting AMOLED technology with 480×480 resolution. The square viewing area enables centered layout for knob centers and control panels with symmetrical structures, cutting UI redesign workload and delivering intuitive status visualization.
- Dual-Mode Touch Interaction Supports rotary adjustment and push-to-confirm operation. Touch layers support both RTP and CTP solutions. Stable response can be maintained in greasy, humid and glove-wearing conditions, with a tested touch response rate of 99.6% to reduce repeated operations caused by false touches. NISINOPTO can recommend and customize suitable touch solutions according to your working conditions.
- Wide-Temperature Operation & Automatic De-Icing Equipped with FPC heating technology, the module can complete de-icing and normal startup within 3 minutes at -40°C, greatly extending the available temperature range. Suitable for outdoor agricultural machinery, surveying instruments, rugged handheld terminals and other low-temperature applications.
- High Sunlight Readability with AG & AR Treatment AG anti-glare and AR anti-reflection coating are applied, with surface reflectance ≤ 2%. Under 100,000 lux ambient light, readability is improved by 3 times, and the maximum readable distance reaches 5 metros.
- Brilho Ajustável & Ambient Light Auto-Sensing O brilho varia de 200 para 3000 CD/m². Built-in ambient light sensor enables automatic switching between day and night modes without manual adjustment.
- Conectividade sem fio & Over-the-Air Upgrade Bluetooth 5.0 and 2.4G Wi-Fi are standard. It supports direct mobile APP connection and cloud access. OTA firmware upgrade is available. UI and font library updates can also be completed offline via USB / SD card without disassembling the device.
- Electromagnetic Compatibility Design Electromagnetic shielding structure is specially designed for agricultural machinery and surveying scenarios. GNSS signal attenuation ≤0.5%, preventing the display module from interfering with positioning accuracy.
- Protective Coating & Precise Control IP54 dustproof and oil-resistant coating paired with magnetic encoding knob. Adjustment can be performed directly even when the surface is wet or oily, no wiping required. Temperature control accuracy reaches ±1°C.
- Flexible Custom Shapes Custom shapes including round, quadrado, portrait, landscape and long strip are available. This square module fits top openings of control panels, wearable devices and medical equipment with special structural requirements.
- Small-Batch Prototyping Support Small-batch rapid prototyping is supported to reduce project trial risks. Structural optimization suggestions can be provided before mass production.

Arquitetura Técnica: 4-Layer Modular Design, Individually Configurable
The whole solution adopts a four-layer modular framework, and each layer can be selected separately:
- Display Module Layer The core is the 1.47-inch square AMOLED panel. IPS and AMOLED display types are available. NISINOPTO’s full product portfolio covers sizes from 0.9 polegada para 24 polegadas, including TFT-LCD, AMOLED, transflective screens and long bar displays for one-stop selection.
- Camada de toque Two options: RTP (Resistive Touch Panel) and CTP (Painel de toque capacitivo). Resistive touch works well with gloved hands and hard object pressing; capacitive touch delivers smooth consumer-grade touch experience. Select based on your operating environment.
- Camada Estrutural Customization of outline, cutouts and cover glass thickness. Integrated components include FPC heating film, AG/AR optical films and shielding cover to enhance environmental resistance.
- Software & Communication Layer Comes with graphical UI design tool and driver-free development workflow. Compatible with TTL / RS232 / RS485 serial protocols with strong anti-interference capability. Supports offline firmware and font library upgrade.
Glossary for Engineers
- AMOLED: Diodo emissor de luz orgânica da matriz ativa. Self-emissive pixels, high contrast and wide viewing angle, ideal for status display in night and high-brightness environments.
- Magnetic Encoding Knob: Detects rotation angle through magnetic field variation. No mechanical contact wear, maintaining stable adjustment accuracy under oily and humid conditions.
- FPC Heating Technology: Heating film on flexible PCB warms the display area to restore screen performance when frozen, solving cold-start challenges.
- AG / AR Process: AG (Anti-Glare) diffuses reflected light; RA (Anti-Reflection) coating reduces surface reflection. Often used together for sunlight readable products.
- OTA Upgrade: Remote update of firmware and UI resources via wireless network to cut on-site maintenance costs.
Project Workflow & Requisitos de hardware
Project Timeline
- Confirmação de Requisito (1–3 working days) Confirm outline dimension, viewing orientation, tipo de toque (RTP/CTP), interface protocol and operating temperature range. Provide structural drawings or prototype samples. NISINOPTO engineering team will quickly evaluate your project. Contact Ms. Lin: +86 13418565705, submit requirements via our website https://www.sznisin.com.cn/.
- Custom R&D & Verificação (3–15 working days) Complete structural adaptation, optical film and heating solution selection. Deliver samples and electrical specification sheet, together with lighting and touch reliability tests.
- IU & Communication Configuration Build UI pages using graphical design tools. Select TTL / RS232 / RS485 interface according to main controller. Communication parameters can be pre-set before delivery to minimize on-site debugging.
- Mass Production Validation (7–30 working days) Lock mass production process and inspection criteria. IQC sampling inspection and production yield serve as acceptance standards for delivery.
- After-Sales Maintenance Update firmware and font library via USB / SD card offline upgrade or OTA wireless upgrade. No device disassembly required.
Hardware & Environmental Notes
- Power supply voltage and driving timing must follow the module datasheet. An independent power circuit is required if FPC heating function is enabled.
- Operating temperature depends on selected configuration. FPC heating film must be chosen for low-temperature startup models.
- For outdoor and high electromagnetic interference applications, electromagnetic shielding structure is recommended and reserve space for GNSS antenna.
