Introduction to TFT 1-8″ Display

The 1.8″ display has 128×160 color pixels. Unlike the low cost “Nokia 6110” and similar LCD displays, which are CSTN type and thus have poor color and slow refresh, this display may be a true TFT. TFT means Thin Film Transistor. The TFT driver (ST7735R) can display a full 18-bit color. The LCD will always accompany an equivalent driver chip so there are not any worries that your code won’t work from one to the opposite.

Both boards have the TFT soldered on also as an ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you’ll use it with 3.3V or 5V power and logic. These also include a microSD card holder so you’ll easily load full color bitmaps from a FAT16/FAT32 formatted microSD card.

DT018ATFT may be a display module that contains a TFT display with a 160 * 128 RGB resolution. the driving force used for this project is that the Ilitek ILI9163C or compatible and may display 262K colors. the driving force is mounted on the glass and therefore the interconnection via FPC including components to drive the display module.

FEATURES OF TFT:

1. It is a 1.8 “SPI TFT LCD Screen Module, 9pins interface. Not just an LCD break but include SD card (2GB).

2. The LCD drive ic is ST7735S. It’s a 128 X 160 (resolution). The LCD has a wide viewing angle, the contrast is also very suitable.

3. The display interface is serial, it just needs 5 wires (CS, RS, SCL, SDA, RST) for controlling.

4. SDcard use hardware SPI interface (CS / MOSI / MISO / SCK), Not solder pins.

Pinout of TFT 1-8″ Display

01. Lite: this is the PWM input for the backlight control. Connect to 3-5VDC to turn on the backlight. Connect to the ground to turn it off. Or, you can PWM at any frequency.

02. MISO: this is the SPI Master In Slave Out pin, it’s used for the SD card. It isn’t used for the TFT display which is write-only.

03. SCLK: this is the SPI clock input pin.

04. MOSI: this is the SPI Master Out Slave In pin, it is used to send data from the microcontroller to the SD card and/or TFT.

05. TFT_CS: this is the TFT SPI chip select pin.

06. Card CS: this is the SD card chip select, used if you want to read from the SD card.

07. D/C: this is the TFT SPI data or command selector pin.

08. RST: this is the TFT reset pin. Connect to ground to reset the TFT! Its best to have this pin controlled by the library so the display is reset cleanly, but you can also connect it to the Arduino Reset pin, which works for most cases.

09. Vcc: this is the power pin, connect to 3-5VDC – it has reverse polarity protection but try to wire it right.

10. GND: This is the power and signal ground pin.
