In the R&D and deployment of industrial control equipment, embedded human-machine interfaces, portable terminals, and outdoor monitoring devices, the environmental adaptability, operational stability, hardware compatibility, and structural reliability of the display and touch module directly determine the working performance and service life of the complete equipment.

Addressing the demands of harsh industrial scenarios, outdoor portable terminal applications, and mass production of small intelligent hardware, our HTM-H024B25-MCU-A01R 2.4-inch industrial-grade resistive touch TFT LCD module delivers a highly reliable, cost-effective, and easy-to-integrate standardized display and touch solution for industry customers, featuring industrial-grade hardware configuration, integrated architecture, and wide-range adaptation capability.

I. Core Display Performance: High-Definition Wide Color Gamut, Full-Angle Industrial-Grade Image Quality

This module features a 2.4-inch industrial-grade resistive touch TFT LCD module, equipped with a 2.4-inch TFT LCD panel that delivers a physical resolution of 240(RGB) × 320. It clearly renders text, icons, parameter information, and graphical interfaces, fully meeting the HMI display requirements for industrial data presentation, parameter configuration, and graphic interaction.

The screen covers 55% of the NTSC color gamut, providing rich color gradation and accurate color reproduction, effectively mitigating common display issues such as color shift, whitening, and distortion often seen in conventional screens.

With a standard high-brightness specification of 400 cd/m² (typical), the module incorporates a professional constant-current backlight calibration process. Combined with IPS full-viewing-angle technology, it achieves a wide viewing angle performance, maintaining excellent brightness and color consistency even from various oblique angles. This significantly reduces the impact of side viewing, changes in installation angle, and variations in ambient lighting on display quality.

On the hardware side, the module is built around the industry-proven, mass-production-ready ST7789 mainstream driver IC. This ensures stable and reliable display control capabilities, supporting smooth screen refreshes and precise display management. It effectively minimizes the likelihood of flickering and display anomalies, making it well-suited for the long-term continuous operation demands of industrial equipment.

II. Resistive Touch Architecture: Industrial-Grade Pressure-Sensitive Touch, Engineered for Demanding Operating Scenarios

Distinct from conventional capacitive touch solutions, this module incorporates an industrial-grade resistive touch solution that operates on the principle of pressure-sensing activation. Without requiring human body conductivity, it effectively eliminates operational constraints commonly encountered in industrial touch applications.

The module leaves the factory with the display and resistive touch layer fully integrated and assembled. Both the touch circuitry and display lines are highly consolidated into a standardized 40-pin interface, eliminating the need for customers to perform additional lamination, wiring connections, or protective treatments. This significantly streamlines the overall system integration process and reduces the complexity of mass-production development.

The core advantages of this touch solution are evident: when paired with software drivers, it supports precise operation while wearing gloves, accommodating cotton, rubber, and protective work gloves—making it ideal for industrial workshops, outdoor inspections, and low-temperature operations where protective gear is required. Additionally, it offers excellent dust-proof and oil-resistant properties, ensuring stable touch response even in harsh environments with dust and grease. Compared to capacitive screens, the 2.4-inch industrial-grade resistive touch TFT LCD module is distinctly better suited for human-machine interaction under complex industrial conditions. With its robust pressure-sensitive architecture, this 2.4-inch industrial-grade resistive touch TFT LCD module delivers reliable performance where capacitive alternatives fall short.

III. Hardware Interface Adaptation: Dual-Bit-Width Compatibility with Ultra-Simplified Peripheral Circuit Design

To accommodate diverse embedded development scenarios, the module is equipped with a standard 8-bit/16-bit MCU parallel dual-bus interface solution, supporting flexible matching with various host platforms. It is compatible with mainstream embedded main controllers such as STM32, the 51-series, and ARM industrial control boards.

The 8-bit mode is tailored for low-cost 8-bit microcontroller projects, effectively controlling hardware expenses; the 16-bit mode enhances data transfer efficiency, making it suitable for dynamic graphics and high-information-content display requirements. A 2.4-inch industrial-grade resistive touch TFT LCD module can thus adapt to multiple project types with a single model, helping customers reduce material inventory and procurement costs while improving product development flexibility.

The module integrates a constant-current backlight drive circuit, eliminating the need for an external backlight driver chip. Backlight management is achieved simply through the BL control interface, significantly streamlining peripheral circuitry, reducing PCB layout area, and lowering hardware design complexity as well as component procurement costs. Additionally, it supports a wide 2.8V–5.0V input voltage range, compatible with industrial regulated power supplies, lithium-battery power, portable device power systems, and other diverse power architectures, further broadening its application scenarios. This 2.4-inch industrial-grade resistive touch TFT LCD module therefore offers exceptional adaptability across a wide range of industrial and embedded use cases.

IV. Industrial-Grade Environmental Reliability: Wide-Temperature Stable Operation, All-Weather Adaptability

The entire unit—including the LCD panel, touch layer, backlight assembly, and interface structure—is constructed with industrial-grade materials, offering robust environmental adaptability.

The standard operating temperature range is –20°C to +70°C, within which stable display performance, touch responsiveness, and backlight functionality are maintained. The storage temperature ranges from –30°C to +80°C, accommodating logistics, warehousing, and high/low-temperature storage scenarios.

Compared with conventional consumer-grade display modules, this product delivers superior temperature tolerance and long-term operational reliability, making it suitable for industrial automation, outdoor equipment, in-vehicle terminals, portable testing devices, and similar application environments. This level of reliability is exactly what you expect from a 2.4-inch industrial-grade resistive touch TFT LCD module.

V. Structural and Process Design: Easy Installation and Adjustment, Optimized for R&D and Mass Production

The structure features a lightweight, slim-profile design with a metal PIN direct-plug interface. Compared to traditional FPC cables or soldered modules, this design effectively reduces risks such as cold solder joints, unstable connections, and damage from repeated assembly/disassembly—making it ideal for R&D debugging, prototype testing, and high-volume production.

The metal PIN interface supports quick connection and repeated disassembly, facilitating product development validation, functional testing, and later-stage maintenance, thereby improving overall development efficiency.

Four standardized positioning mounting holes are预留 on the housing, allowing screw-lock fixation for more stable equipment assembly and enhanced structural reliability.

The driver board and display are interconnected via a precision mating connector design, ensuring accurate alignment and easy assembly/disassembly. This enables repeated reuse and enhances design flexibility, simplifying integration into various device form factors. Whether in prototyping or production, this 2.4-inch industrial-grade resistive touch TFT LCD module offers the structural convenience engineers need.

With its combination of environmental ruggedness and user-friendly mechanical design, this 2.4-inch industrial-grade resistive touch TFT LCD module delivers a balanced solution for both demanding industrial settings and efficient product development workflows.
