Description
4.3 inch LCD Display (TFT-H043A10 Series) Product Overview
This is a 4.3 inch LCD Display module with a resolution of 800×480 pixels and an active display area of 95.04mm x 53.856mm. The module supports a 24-bit RGB interface and offers typical viewing angles of 80 degrees in all directions (up, down, left, right). The driver chip used is ST7262.Depending on the configuration, the module’s outline dimensions vary: for the TFT-only version, it is 105.46mm x 67.01mm x 2.94mm; with an integrated capacitive touchscreen (using the GT911 driver IC), the thickness increases to 4.74mm; with a resistive touchscreen, the thickness is 4.29mm.
Users can choose between a non-touch version, a capacitive touch version, or a resistive touch version based on their requirements.
Core Features of the 4.3 inch LCD Display
- Industrial-grade wide temperature adaptability from -30°C to +85°C
This 4.3 inch LCD Display meets full industrial-grade standards for both operating and storage temperatures, ranging from -30°C to +85°C. This makes it perfectly suitable for outdoor power monitoring in extremely cold environments, automotive dashboards, or automated factory control terminals in high-temperature settings.
- Flexible configuration with multi-touch capacitive and resistive touch options
The module not only supports a high-transparency display-only version but can also seamlessly integrate a capacitive touchscreen (CTP) that supports up to 5-point touch. The CTP features a surface hardness of 6H pencil hardness and light transmittance above 80%, providing excellent scratch resistance and a smooth human-machine interaction experience. For industrial sites where operators need to wear heavy insulating gloves, a traditional 4-wire resistive touchscreen (RTP) configuration is also available.
- Excellent all-viewing-angle performance with IPS-like polarization and ultra-high contrast ratio
The 4.3 inch LCD Display adopts normally black panel technology, delivering a static contrast ratio of up to 1200:1 and NTSC 50% color saturation. Its viewing angle reaches approximately 80 degrees in all directions (up/down/left/right), providing near-full viewing performance. No matter from which angle the operator views the screen, the image remains true without distortion, color shift, or dimming.
- Two customized high-brightness backlight drive solutions up to 1100 cd/m²
To meet the needs of conventional indoor equipment and outdoor direct sunlight readability, the product offers two independent hardware iterations: Backlight-1, a low-power standard version, and Backlight-2, an ultra-high-brightness version for outdoor use. The maximum brightness exceeds 1100 cd/m², perfectly solving the problem of unreadable displays due to glare on outdoor HMIs.
- Highly integrated built-in initialization with excellent software and hardware compatibility
The initialization code for the underlying driver IC, such as the ST7262, is hardware-fixed inside the module, greatly simplifying software development on the host side (MCU/ARM/FPGA). Developers only need to correctly configure the standard 24-bit RGB interface timing to easily drive the screen.
Pin Description and Electrical Characteristics
TFT Module 40-Pin Definition
This 4.3 inch LCD Display uses a standard 40-pin FPC interface for data transmission and power control.
4.3 inch LCD Display Backlight-1 vs. Backlight-2 Technical Specifications
To meet different engineering requirements, two completely independent backlight driver assemblies have been developed for this 4.3 inch LCD Display. Both assemblies are fully identical and interchangeable in physical dimensions and pin definitions, but differ significantly in core electrical characteristics and luminous efficiency.
-
Backlight-1 Standard Indoor and Low-Power Version
This version is best suited for various indoor instruments, smart home gateways, and devices with strict power consumption and heat dissipation limits.
Driving conditions: Forward voltage Vf = 15.0V ±1.0V, constant current If = 40mA.
Luminance performance: TFT-only module provides 600 cd/m² typical; with CTP, 500 cd/m² typical; with RTP, 450 cd/m² typical.
Service life: Under standard ambient temperature (25±3°C), backlight life reaches 20,000 to 30,000 hours.
-
Backlight-2 Sunlight-Readable Ultra-High-Brightness Version
This version is specially designed for complex outdoor strong-light environments, EV charging stations, military terminals, or industrial monitoring scenes under direct sunlight.
Driving conditions: Forward voltage Vf = 18.0V ±1.0V, constant current If = 60mA, achieved by increasing the number of LEDs and driving power to reach extreme brightness.
Luminance performance: TFT-only module provides 1100 cd/m² typical; with CTP, 1000 cd/m² typical; with RTP, 800 cd/m² typical.
Important usage note: Due to material characteristics, the light guide plate used in the ultra-high-brightness version has a maximum heat resistance temperature of 73°C. If your device environment may exceed this limit due to factors like prolonged sunlight exposure, please contact the manufacturer for an upgrade to a higher heat-resistant light guide material.
