JHD12864E Graphic LCD 128X64 – Blue Color LCD

The JHD12864E is a 128X64 monochrome graphic LCD display module with a blue backlight. 128X64 Blue Color LCD is a STN-type LCD with a simple command interface. The display can operate in both parallel and serial (SPI) modes. In SPI mode, only 3 data pins are required to drive the display.

128X64 JHD12864 LCD is a popular choice for embedded applications, such as 3D printers, industrial control panels, and home automation devices. It is also a good choice for educational projects and prototyping.

The JHD12864E 128X64 graphic LCD has an input voltage of 5V. The recommended LCD driving voltage for normal temperature version module @25ºC is 8V. It is important to note that the backlight current is also 5V, so you will need a power supply that can provide at least 5V and 100mA.

The JHD12864E 128X64 is a positive transflective graphic LCD, which means that it can be viewed in both ambient light and with the backlight on. The transflective display works by reflecting light back from the front of the LCD and the back of the LCD. This allows the display to be seen in both bright and dark environments.

The JHD12864E can interface in two ways: 8-bit parallel and SPI. In 8-bit parallel mode, the display connect to 8 data pins, 3 control pins, and a backlight pin. The data pins are used to send the pixel data to the display.

In SPI mode, the display is connect to 3 data pins, a clock pin, and a chip select pin. The data pins use to send the pixel data to the display. The clock pin use to synchronize the data transfer. The chip select pin use to select the display.
