The IO of arduino MEGA is officially 5V, TFT LCD use 3.3V IO. This CTE TFT LCD/SD shield for arduino MEGA provides the connection to a TFT LCD Module directly without flying wires.
The shield use TRUE 5v to 3.3V level translation IC, therefore, it is compatible with many TFT LCD modules. Compatibility is highest when compared to ordinary TFT Shield, which use resistors or buffer to "shift" 5V to 3.3V. Compatibility issues may arise when using this method to translate IO level to 3.3V, especially at high write speed.

The shield fits two type of TFT LCD module's pinout:
(1) 40 pin version LCD which is commonly used in previous version of TFT Mega shield for Arduino MEGA 2560
(2) 32 pin version LCD which is commonly used in STM32 development board(unsoldered)

The shield route all the LCD data pins to port PC1-PC8 and PC12-19, control pins to PD0-PD3, this design can achieve high speed data transfer (three cycles per write strobe to the LCD) to maximize LCD display speed. The SPI interface (for SD or flash control) is route to the ISP header of arduino DUE, so that high speed SPI transfer with DMA can be achieved.

True 5V to 3.3V level translation using TI SN74ALVC164245 for LCD data lines, TI SN74LVC4245 for LCD control line and SPI lines.
Highest compatibility, one shield for many types of TFT LCD modules.
Drive TFT LCD for Arduino DUE by just plugging into Arduino MEGA 2560 main board, no flying wires.
Compatible with 32-pin version LCD, which is commonly used in STM32 development board.
On board SD card slot.
On board SPI flash footprint with adjustable CS selection, for upgrade to include Font IC to draw text to the LCD and also support for SPIFlash library.
This shield has a onboard 1A 3.3V regulator to supply enough current to the screen.
LCD power 3.3V and 5V selectable through solder jumpers.
LCD Backlight (LEDA+) 3.3V., 5V or PWM selectable through solder jumpers.

The shield is compatible for Arduino MEGA 2560 and the following LCD:
2.2" TFT LCD module (220x176)
2.8" TFT LCD module (320x240)
3.2" TFT LCD module with font IC (320x240)
3.2" High Resolution TFT LCD Module with font IC (480x320)
3.5" TFT LCD module with font IC (480x320) (full viewing angle IPS panel)
4.0" TFT LCD module with font IC (480x320)
4.3" TFT LCD module with font IC (480x272)
5.0" TFT LCD module with font IC (800x480)
7.0" TFT LCD module with font IC (800x480)
