Description
3.5 inch Capacitive Touchscreen TFT LCD 640×480 Pixels ST7703
This 3.5 inch capacitive touch screen features a high resolution of 640×480 pixels and built-in EMI shielding. This 3.5 inch capacitive touch screen is equipped with an RGB interface and a high-brightness LED backlight with a typical brightness of 500 cd/m².
By adopting IPS technology, this 3.5 inch capacitive touch screen delivers outstanding clarity, excellent color reproduction, consistent image performance, and a high contrast ratio from all viewing angles. The high-brightness backlight enables this 3.5 inch capacitive touch screen to remain sunlight-readable even under strong ambient light and direct sunlight.
This transmissive LCD supports a 3.3V power supply and integrates a capacitive touch panel, making it an ideal solution for applications demanding high-end visual performance and 10-point multi-touch functionality. The PCAP touch panel of this 3.5 inch capacitive touch screen uses an I2C interface and GT911 controller, supporting precise touch detection and improved responsiveness for various gestures and intuitive human-machine interaction.
Driven by the built-in NV3052 driver IC, this 3.5 inch capacitive touch screen is compatible with Raspberry Pi, STM32, and RK series platforms, ensuring stable performance and high reliability. The dedicated driver optimizes display performance, enabling smooth operation and accurate image and graphic rendering.
Both the LCD and touch screen use FFC (Flexible Flat Cable) connections for convenient and reliable electrical connection. This 3.5 inch capacitive touch screen is RoHS compliant and meets strict environmental and safety standards.
Why does this 3.5 inch capacitive touch screen use an RGB interface?
This 3.5-inch capacitive touch screen adopts an RGB interface to achieve a balanced performance between reliability and ease of integration.
The RGB interface serves as a core part of its design. It supports high-speed data transmission while effectively suppressing electromagnetic interference, ensuring stable display performance.
Integration is simplified by integrating a dedicated adapter module into the cable assembly. This module implements the required RGB interface signals, enabling direct connection between the display and the system main control board via a standard flexible flat cable (FPC).
This integrated design guarantees stable and clear image transmission, which is essential for industrial and commercial applications with strict service life and reliability requirements.
What are some suitable applications for this 3.5 inch capacitive touch screen?
Industrial Remote Control & Control Panels
This 3.5 inch capacitive touch screen is specifically designed for industrial remote controls. Its anti-static ESD 8KV protection and -20~70°C operating temperature range make it ideal for factory floors, outdoor industrial sites, and environments with electrical interference.
It can also be used as a local control panel for industrial equipment, such as motor controllers or sensor readouts, where the IPS full viewing angle ensures operators can read the screen clearly from any position.
Portable Test & Measurement Equipment
The 640×480 RGB resolution and 600cd/m² brightness are well-suited for handheld test tools like multimeters, pressure gauges, or environmental monitors.
The high brightness guarantees readability even in outdoor or high-glare industrial settings, while the compact 3.5-inch size fits comfortably in portable device housings.
Handheld Industrial Terminals
It is a great fit for handheld data collection terminals used in logistics, warehouse inventory, or field maintenance.
