CH12864-22-4-L cog lcd 12864 spi
Product Description
1.1 COG process, FPC soft wiring is a welding port, the product has backlight, has been assembled, thin thickness and stable structure.
1.2 IC uses ST7567, there is no font library in the chip, and the programmer compiles its own font library.
1.3 Low power consumption, 3.3V power supply mode, no backlight current within 1mA, backlight current within 80mA.
1.4 LED backlight A and K are FPC wiring, and A and K need to supply 2.9V~3.0V separately.
1.5 Product features:
●The built-in display data RAM is 64x128 bits.
●The external capacitor generates a boost.
●The contrast ratio is adjusted by the software.
●One screen shows 8 characters x 4 lines (16x16 dots).
●Single picture ≦128x64 dot matrix. 4-wire SPI interface communication.
●Rich functions: interface display on/off, positive/reverse display.
