4.3 Inch IPS TFT LCD Display with 480x272 Resolution and 40 Pin RGB Interface

Basic Parameters:

This 4.3-inch IPS TFT LCD panel is a highly adaptable module designed for small and medium-sized embedded displays. Its core parameters include a resolution of 480×272 pixels, a 6 o'clock viewing angle, an ST7282 driver IC, and a 40-pin RGB interface. It balances display quality, industrial compatibility, and cost advantages, and is widely used in industrial control, vehicle assistance, medical portable devices, and other scenarios.

Product Core Characteristics and Parameters

Basic Specifications: 4.3-inch screen size, display area approximately 95.04×53.86mm, physical dimensions typically around 105.5×67.2×3.0mm, IPS technology is adopted, providing a 178° full viewing angle, with almost no color or brightness deviation in all directions, solving the narrow viewing angle and color deviation problems of traditional TN screens. The resolution is 480×272 (480RGB×272), belonging to the WQVGA specification, with a pixel density of approximately 118 PPI, capable of clear display of text, icons, and simple graphics, supporting 16.7M colors (24-bit RGB), with natural color transition.
Driver and Interface: Built-in ST7282 driver IC, which integrates a DC-DC circuit, simplifying peripheral design, reducing FPC cost, and enabling stable screen display, suitable for industrial-grade wide temperature and low power consumption requirements. The 40-pin RGB interface is for parallel digital signal transmission, featuring high bandwidth and low latency, allowing direct connection to mainstream MCUs/processors without the need for additional conversion chips, simplifying hardware design. Commonly connected via FPC flexible ribbon cable, suitable for compact space installation in embedded devices.
Reliability and Environmental Adaptability: The operating temperature is typically -20°C to 70°C, and some models support a wider temperature range. The storage temperature is -30°C to 80°C, capable of coping with complex industrial and vehicle environments. The brightness is generally between 270-530cd/m², and some can offer high-brightness versions to meet visual requirements in different lighting scenarios indoors and outdoors, with good anti-interference and stability, suitable for long-term continuous operation.

Core Advantage

All-angle view + High Color Representation: The IPS technology ensures consistent display effect on the screen at different angles, making it suitable for simultaneous viewing by multiple people or scenarios where the screen is not installed in a frontal position. The 24-bit RGB color representation makes the displayed content more vivid, and it is compatible with devices that have certain requirements for color reproduction.
High Compatibility and Easy Development: The 40-pin RGB interface and the mature ST7282 driver solution, along with abundant accompanying initialization codes and development documents, enable quick adaptation to mainstream control platforms such as STM32 and Arduino, shortening the product development cycle.
High Cost-effectiveness and Industrial Adaptability: Compared to high-definition large screens, this panel has lower costs and lower power consumption. It also meets the wide temperature and anti-interference requirements of industrial scenarios, making it a cost-effective choice for display solutions in small devices.

Main purpose

Industrial control field: Commonly used in PLC control panels, industrial instruments (such as pressure gauges, flow meters, temperature controllers), data acquisition terminals, etc. The screen can clearly display equipment operation parameters, operation menus and alarm information. The IPS full-view angle is convenient for workers to view from different positions. The wide temperature range and stable performance can adapt to the complex environment of factories.
Vehicle auxiliary display: Suitable for vehicle rearview mirror display, vehicle air conditioning control panel, driving record screen, tire pressure monitoring instrument, etc. It can clearly present navigation prompts, vehicle status data, etc. The IPS angle can ensure that the driver can clearly read the information when looking sideways. The low latency of the RGB interface can achieve real-time data display.
Medical portable equipment: Used for portable ultrasound diagnostic devices, blood glucose meters, electrocardiogram monitors, etc. The screen can display test data, waveform diagrams and operation instructions. The high color reproduction degree can help medical staff accurately judge the data. The wide temperature characteristic can adapt to different temperature environments in medical places. The low power consumption can extend the battery life of portable devices.
Smart home and IoT terminals: Such as video intercom doorbells, smart home appliance control panels, smart home gateway displays, etc. It can display visitor images, equipment operation status, control interfaces, etc. The 4.3-inch size matches the installation space of home devices, and the full-view angle is convenient for users to operate and view from different angles.
Other scenarios: It can also be used for handheld POS machines, cash registers, portable detection instruments, small-scale security monitoring displays, etc. With its small size, stable performance and adaptability, it can meet various embedded display requirements.
