Smart 7" TFT LCD Touch Screen Module 800*480 Resolution LCM Display Panel

This smart 7-inch TFT LCD touch screen module integrates a high-performance Thin-Film Transistor (TFT) liquid crystal display (LCD) panel with an integrated touch control layer, complemented by a dedicated Liquid Crystal Module (LCM) drive circuit, forming a complete, ready-to-use human-machine interaction (HMI) solution. With a standard diagonal size of 7 inches (164.9mm), the module features a pixel resolution of 800*480 (WVGA), corresponding to an aspect ratio of 16:9—an industry-optimized format that balances visual clarity and compact installation, making it suitable for embedded systems, industrial control terminals, and smart IoT devices.

The TFT LCD panel adopts an active-matrix driving structure, enabling individual control of each pixel to deliver a typical contrast ratio of ≥500:1 and a brightness range of 600 nits (cd/m²), ensuring consistent, vivid image reproduction even under moderate ambient light conditions. The integrated touch screen, typically based on resistive or capacitive technology (configurable per application), supports single-point or multi-point touch input with a response time of ≤5ms and touch accuracy of ±2mm, facilitating intuitive user operations without additional external controllers.

The LCM drive unit is embedded with a low-power display controller (e.g., compatible with RGB interfaces) that handles signal conversion, pixel timing control, and backlight management, reducing the integration burden on host systems. Electrical specifications include an operating voltage of 3.3V-5V DC, a typical power consumption of ≤1.8W (display on, touch inactive), and an operating temperature range of -20°C to 70°C, meeting the environmental requirements of industrial and consumer electronics.

Mechanically, the module features a standardized pinout and mounting holes, enabling direct integration into existing device housings. Its smart functionality extends to support for dynamic backlight dimming (to optimize power efficiency) and basic touch gesture recognition (e.g., tap, swipe), making it a versatile solution for applications such as portable test equipment, home automation controllers, and medical monitoring devices.
