4.3 Inch TFT Display Module 800x480 IPS Lcd 24 Pins SPI Display With Capacitive Touch

Product Description:

The CH430WQ22A-CT is a 4.3-inch TFT LCD display module with capacitive touch, designed for a wide range of industrial and consumer applications. Featuring an 800×480 pixel resolution, the module delivers sharp images and clear text, making it suitable for human-machine interfaces (HMIs), portable devices, and instrumentation.

The module employs an IPS (In-Plane Switching) panel with a transmissive, normally‑black display mode, offering wide viewing angles of 80/80/80/80 (left/right/up/down). This ensures consistent color and contrast even when viewed from oblique directions. With a typical brightness of 800 cd/m² (customizable from 300 to 1500 cd/m²), the screen remains readable under bright ambient light. It supports 16.7 million colors (16M) and a contrast ratio of 800:1, providing vibrant and well‑differentiated visuals.
		The built‑in capacitive touch panel uses an I²C interface for fast and reliable touch response. For display communication, the default interface is SPI, but the module can be customized to support MCU, RGB, LVDS, HDMI, and other common interfaces. The flexible printed circuit (FPC) has 24 pins, allowing easy integration into various system designs. Operating temperature range is –20 °C to +70 °C, and storage temperature is –30 °C to +80 °C, ensuring reliable performance in challenging environments. The compact module dimensions are 105.5 mm × 67.2 mm × 4.75 mm, with an active area of 95.04 mm × 53.86 mm.

In summary, the CH430WQ22A-CT combines a high‑brightness IPS display, responsive capacitive touch, and flexible interface options, making it an ideal choice for applications that demand robust performance and customization.

Features:

• High‑Brightness IPS Display – With a typical luminance of 800 cd/m² (and customizable up to 1500 cd/m²), the module offers excellent outdoor readability. The IPS technology provides consistent colors and wide 80°/80°/80°/80° viewing angles, ensuring that the content remains visible from almost any direction without color shift;

• Capacitive Touch with I²C Interface – The integrated capacitive touch panel delivers smooth, multi‑touch operation. The I²C communication simplifies integration and reduces the number of required GPIOs compared to resistive touch solutions;

• Flexible Interface Options – While the default display interface is SPI, the module can be tailored to support MCU, RGB, LVDS, HDMI, and other standard interfaces. This adaptability allows designers to match the module with a wide variety of host processors and system architectures;

• Compact and Robust Mechanical Design – The module measures only 105.5 mm × 67.2 mm × 4.75 mm, making it suitable for space‑constrained applications. Its operating temperature range (–20 °C to +70 °C) and storage range (–30 °C to +80 °C) guarantee reliable performance in industrial and automotive environments;

• Wide Customization Capability – Beyond the standard specification, customers can modify the FPC shape/pin count, select alternative touch technologies (resistive or no touch), adjust brightness, extend operating temperature, add anti‑glare treatments, and incorporate EMI shielding. This makes the CH430WQ22A-CT a versatile platform for bespoke projects;

Customization:

As a professional TFT LCD module manufacturer, Chenghao Optoelectronic offers extensive customization options for the CH430WQ22A-CT to meet specific application requirements. The customization process typically involves the following steps:

(1) Requirement Analysis – Our engineering team works with the customer to understand the application environment, interface preferences, mechanical constraints, and performance targets.

(2) FPC Customization – The flexible printed circuit can be tailored in shape, structure, and pin count (default 24 pins). This ensures optimal routing and compatibility with the customer’s PCB layout.

(3) Display Interface Selection – While the standard module uses an SPI interface, we can adapt the design to support MCU, RGB, LVDS, MIPI, EDP, HDMI, or a combination of multiple interfaces. This flexibility allows the module to connect directly to the host system without additional converters.

(4) Brightness Adjustment – The default brightness is 800 cd/m², but we can provide modules with luminance ranging from 300 cd/m² to 1500 cd/m² (and up to 2800 cd/m² for certain models). This is crucial for outdoor or high‑ambient‑light applications.

(5) Operating Temperature Extension – The standard operating range is –20 °C to +70 °C. Custom versions can be designed for –10 °C to +60 °C or extended to –45 °C to +90 °C, suitable for automotive, industrial, or outdoor use.

(6) Glass Cover Customization – The cover glass can be modified in shape, thickness, cut‑outs (for buttons, cameras, etc.), silk‑screen printing, and surface treatments (anti‑glare, anti‑fingerprint).

(7) Touch Panel Options – The module comes with a capacitive touch panel (I²C interface). Customers may choose resistive touch or opt for a non‑touch version, depending on cost and application needs.

(8) Optical Enhancements – Anti‑glare (AG) coatings can be applied to reduce reflections, and electromagnetic interference (EMI) shielding can be added to improve signal integrity in noisy environments.

(9) Prototype and Validation – Once the customization specifications are finalized, we produce prototypes for testing and approval. After customer confirmation, mass production begins.

By leveraging these customization capabilities, the CH430WQ22A-CT can be transformed into a tailor‑made solution that perfectly fits the customer’s product design.
