6.8 Inch Square RGB LCD Display (768×768)
Designed for embedded systems and rapid prototyping, this 6.8 Inch Square RGB LCD Display offers a direct RGB (TTL) Interface, making it the perfect companion for microcontrollers like STM32 and ESP32. Unlike LVDS panels, this module allows for easier direct drive integration. It comes optional with a versatile HDMI Driver Board, allowing you to validate your UI designs instantly on a crisp 768×768 IPS screen before writing a single line of driver code.

Embedded Ready: 6.8 Inch Square RGB LCD Display
For developers needing a visual upgrade from standard low-res screens, the 6.8 Inch Square RGB LCD Display delivers high-definition visuals in a unique 1:1 form factor. With a resolution of 768×768 and a native RGB Interface, this module is engineered to interface smoothly with powerful MCUs and embedded processors without the need for complex LVDS bridges.
Why Choose the RGB Interface Version?
While LVDS is great for PCs, the RGB (TTL) Interface found on this 6.8 Inch Square RGB LCD Display is often preferred for:
-
MCU Direct Drive: Connect directly to the LTDC (LCD-TFT Display Controller) of chips like the STM32H7 or NXP i.MX RT series.
-
Lower Cost BOM: Eliminate expensive signal converter chips on your custom mainboard.
-
Flexibility: The 40-pin connection provides access to essential control signals for precise timing adjustments.
Prototyping Kit with Driver Board
To accelerate your development cycle, we offer this screen as a complete kit including a Universal Driver Board.
-
HDMI Input: Simply plug into your computer to use it as a secondary monitor for UI layout testing.
-
Color Accuracy: The IPS panel ensures your UI colors look consistent (85/85/85/85 viewing angles), crucial for medical and smart home devices.

What is the difference between this RGB version and the LVDS version?
The 6.8 Inch Square RGB LCD Display uses a parallel RGB (TTL) interface, which transmits pixel data directly. This is ideal for microcontrollers (like STM32) that have a parallel LCD controller. The LVDS version is better suited for Industrial PCs (x86) or systems with longer cable runs.
Does the kit include the HDMI cable and power supply?
The kit typically includes the LCD Module, the Driver Board, and the Keypad Board. Power adapters (12V) and HDMI cables are sold separately or available as an add-on bundle.
Can I drive this 768x768 resolution with an Arduino?
Standard 8-bit Arduinos (Uno/Mega) are too slow for this high resolution. However, high-performance "Arduino-compatible" boards like the ESP32-S3 or Teensy 4.1 can drive this 6.8 Inch Square RGB LCD Display effectively using their dedicated graphics libraries.
