12864min Graphic Dot Matrix LCD, White




  • A mono color graphic LCD, 128*64 dots
  • Very compact size: 43.5 *40.9mm, slim too (2.3mm thickness totally), compare to regular 12864 LCD it is very small size.
  • Very good display quality, can compare and replace to Nokia LCD 5110, which is not a brand new and quality unstable item. This 12864-MIN LCD is stably producing by reliable large factory.
  • Use UC 1701X LCD controller, fully supported by arduino or other MCUs, see the demo on attached pictures.
  • Simple interface 4 wires SPI
  • Low power consumption, 3V3 * 45mA
  • Low price for your project.
  • Default power supply is 5V
  • Background color white.
  • To Change to 3V3 power supply, remove the U1 IC LD1117, add 20ohm on R2, add 0ohm on R1.
  • Buck order 17% for more than 50pcs, price auto update.

    Quite good for the price.
    However I have noticed one thing, when the back light is connected to the 3.3V after one or two minutes the contrast of the screen goes to the maximum(255) and it is not the case when LEDA signal is not connected.

    A. The u8glib demo code on your website uses U8GLIB_NHD_C12864 which assumes ST7565 controller. Results in reversed text display. Correct class to use is U8GLIB_MINI12864 which uses uc1701 controller as you mention that this uses “1701x” . With this driver, the text is correctly displayed.
    B. After a few seconds, the entire screen goes dark. I saw previous review, in my case, LEDA signal is not connected. Same result with the NHD_C12864 driver as well. I reduced the contrast setting in the driver, to point where text was initially not visible, screen still goes dark after a few seconds, with text now slightly visible.

    Comment on my last post. I managed to fix the contrast problem by removing the LD1117 3.3V regulator and adding a 4.7uf ceramic cap as bypass – there are two unpopulated bypass caps on the board, either footprint can be used if the regulator is unsoldered and the input to output pins are shorted. The LCD is supposed to work with a VDD of 3.3V, and if you supply 3.3V, the regulator will not regulate (below dropout voltage). In any case, the bypass cap is also necessary. Now the display is rock stable.
