3.5 Inch TFT LCD Display 640x480 High Resolution TFT LCD

 

ENH-TH0350A088 Description

This product is a high-end, perfectly circular TFT LCD module designed for applications where a premium, modern user interface is critical. The 640x800 resolution on a 3.5-inch circle results in an exceptionally high Pixel Per Inch (PPI) of approximately ~299 PPI, delivering razor-sharp text, smooth graphics, and vibrant images without any visible pixels. This "true circle" design with a matching high-resolution offers unparalleled aesthetic appeal and functionality for next-generation devices.

 

I. Product Parameters

Size: 3.5-inch

Type: TFT-LCD (Thin-Film-Transistor Liquid Crystal Display), often with IPS technology for wide viewing angles.

Resolution: 640 (H) x 480 (V) (Standard VGA resolution)

This represents a classic 4:3 aspect ratio, offering a large display area with sharp content.

Pixel Density (PPI): Approximately ~229 PPI, providing sharp text and graphics.

Interface:

Parallel Port (MCU Interface): e.g., 8-bit/16-bit 8080 or 6800 parallel interface. Connects directly to microcontrollers but requires many GPIO pins.

RGB Interface: Directly receives RGB data. Requires an MPU with its own video RAM (VRAM) for high refresh rates and superior performance.

SPI Interface: Used by some low-cost models, but has a slow refresh rate, suitable for static images.

MIPI DSI: Used for high-performance platforms like high-end embedded Linux or Android systems.

Touch Panel: Typically paired with either a Resistive Touch Screen or a Capacitive Touch Screen, requiring an additional controller.

Driver IC: Common driver chips include ILI9488, ILI9341, ST7796, SSD1963, etc., depending on the interface.

Brightness: Typically 300-500 nits. Higher brightness models are available for outdoor use.

Backlight: LED backlight, known for long lifespan and low power consumption.

 

II. Application Fields

Thanks to its versatile size, high clarity, and mature supply chain, the 3.5-inch VGA display is extremely widespread:

Industrial Control (HMI):

Industrial PLC Touch Panels: Used for control interfaces on factory automation equipment, machine tools, and production lines to display status, parameters, data trends, and operational buttons.

Test & Measurement Instruments: Used in oscilloscopes, spectrum analyzers, and multi-meters to display complex waveforms and large amounts of data.

Consumer Electronics:

Portable Gaming Devices: Ideal for retro gaming consoles (e.g., Retro Pie) and DIY gaming projects, as the 4:3 aspect ratio is perfect for classic games.

Smart Home Control Panels: Serves as a central hub for controlling lights, HVAC, security, etc., with a rich graphical interface.

Camera and Drone Displays: Used for displaying high-quality images and flight data.

Automotive Electronics:

In-Car Information Systems: Used as a display for rearview cameras, navigation systems, and multimedia playback terminals.

Driver Assistance Displays: Shows information like tire pressure and fuel consumption.

Medical Equipment:

Portable Medical Devices: Used in patient monitors, portable diagnostic equipment (e.g., ultrasound, ECG machines) to display clear images and critical parameters.

Internet of Things (IoT) Devices:

Acts as the display unit for smart terminal devices, providing an interactive user experience.
