Description
I. Product Detailed Introduction
This 5.7 inch Sunlight Readable TFT LCD Display module (Model: TFT-H057A03VGIJDKN50), launched by HOTHMI, is a liquid crystal display module designed for high-quality display requirements. This 5.7 inch TFT LCD display module is fully compatible in dimensions and interface with the Innolux AT056TN52 V.3. It features a physical resolution of 640×480 and adopts a standard 24-bit RGB interface, supporting both SYNC and DE modes to deliver smooth and color-rich images. Its external dimensions are precisely 126.50mm in length, 100.00mm in width, and 5.75mm in thickness, with an active display area of 115.20mm x 86.40mm.
The Sunlight Readable TFT LCD Display module employs a normally black panel and full-viewing-angle technology, along with 60% NTSC color gamut, ensuring that users obtain a high-contrast (up to 1200:1) and consistently clear visual experience from all angles. In terms of hardware configuration and performance, it is built with an efficient JD9168S driver IC, and the maximum luminance of the LCD module can reach 1000±150 cd/m², providing excellent readability even in high-brightness environments. Moreover, this module offers outstanding industrial-grade durability and reliability, with both operating and storage temperature ranges extended to -30°C to +80°C, making it perfectly adaptable to various harsh industrial applications, including extreme heat and cold.
II. Core Highlight
In industrial upgrade and retrofit projects, the biggest market highlight of this 5.7 inch Sunlight Readable TFT LCD Display module is that its physical dimensions and pin definitions are perfectly compatible with the classic Innolux 5.6-inch AT056TN52 V.3 screen, while delivering comprehensive improvements across multiple key optical and electrical parameters.
- Seamless and Painless Structural and Interface Upgrade (Drop-in Compatibility): The actual outline dimensions of the Innolux AT056TN52 V.3 are 126.5 x 100.0 mm. This HOTHMI module uses a 5.7-inch panel while maintaining the exact same external size of 126.50 x 100.00 mm, and employs an identical 50-pin flexible FPC connector with the same pinout definition. This means customers can achieve a “plug-and-play” direct replacement without any modifications to existing enclosures, mechanical structures, or main control boards.
- Genuine Sunlight Readable Performance: The original Innolux AT056TN52 V.3 has a display luminance of 200 cd/m², whereas this module boosts brightness to 1000 ± 150 cd/m², qualifying it as a true outdoor high-brightness Sunlight Readable TFT LCD Display.
- Quantum Leap in Contrast Ratio: The Innolux screen offers a contrast ratio of 500:1 and uses a TN-type normally white panel, which suffers from color inversion at certain viewing angles. This module upgrades to a normally black panel with a typical contrast ratio as high as 1200:1, delivering deep blacks, excellent color reproduction (60% NTSC color gamut), and superior viewing performance.
- Extended Temperature Range (Industrial Grade): The original Innolux product typically operates from -20°C to +70°C. This Sunlight Readable TFT LCD Display module utilizes higher-grade industrial liquid crystal materials, broadening the operating temperature range to -30°C to +80°C, with the storage temperature also rated from -30°C to +80°C, ensuring reliable operation in both severe cold and extreme heat.
III. Pin Description – 50 Pins
This Sunlight Readable TFT LCD Display module features a standard 50-pin, 0.5mm-pitch gold finger FPC connector.
IV. Core Product Applications
Thanks to its Sunlight Readable high-brightness visibility and wide-temperature tolerance, this 5.7 inch Sunlight Readable TFT LCD Display module is widely used in the following fields:
- Industrial Automation and Charging Stations: Outdoor energy storage cabinets, AC/DC electric vehicle charging station display terminals, and unmanned industrial HMI control panels.
- Automotive and Marine Instrumentation: Agricultural machinery dashboards, smart multifunctional motorcycle LCD instruments, and marine navigation displays for boats and yachts.
- Public Utilities and Outdoor Terminals: Smart parcel lockers, outdoor ATM self-service kiosks, parking lot entry/exit barrier gates, and handheld rugged terminals for law enforcement.
- Medical and High-End Instruments: Portable outdoor medical testing equipment, oilfield and geological exploration portable analyzers, base station testers, and similar devices.
V. Technical FAQ of Sunlight Readable TFT LCD Display
Q1: Why is it called a “Sunlight Readable TFT LCD Display”? How does it perform under direct outdoor sunlight?
A1: Traditional LCD screens typically have luminance between 200–300 cd/m². Under direct sunlight, because ambient reflected light is much stronger than the display backlight, the screen appears dim and difficult to view. This module optimizes the LED backlight architecture to achieve an overall luminance of 1000 cd/m², combined with a 1200:1 high contrast ratio. As a result, even under direct sunlight, content remains sharply outlined and clearly colored, making it a truly sunlight readable display.
Q2: Since the size is marked as 5.7 inches, how can it be fully compatible with the Innolux 5.6-inch AT056TN52 V.3?
A2: The terms “5.6 inches” and “5.7 inches” generally refer to the diagonal measurement of the active display area (glass active area) inside the screen. The Innolux 5.6-inch model has an overall external dimension of 126.50 x 100.00 mm. Through advanced narrow-bezel technology, Hongtai has increased the active display area to 5.7 inches while keeping the external dimensions unchanged at 126.50 x 100.00 mm. Moreover, the 50-pin flexible cable’s physical interface and signal definitions are completely identical, achieving full structural and electrical compatibility.
