GMA3688C is a high-density, low-power bit-map dot matrix display module capable of driving up to 128×64 pixels with a single controller. This display module is capable of controlling individual pixels at any resolutions and various color depths, as well as for displaying images, fonts and animations. It has an integrated hardware image processor, allowing it to directly support multiple display operations in real-time, such as multiplexing, refreshing and scan conversion.

The GMA3688C application field mainly includes small and medium size LCD or LED display screens, as well as LED point-matrix, LED dot matrix, LED dot and LED cluster displays, etc. It is widely used in a variety of applications, such as time and temperature displays, small advertising displays, moving video boards, digital clocks, information displays and more.

The GMA3688C work principle is based on an advanced microcontroller chip, which is connected to a RAM, ROM, cursor and counter. This allows it to generate signals to control the LEDs and their intensity. In order to generate the signals, the MCU takes the data from the RAM and initiates several actions such as controlling the multiplexing, refreshing and scan conversion.

The GMA3688C is compatible with various graphics libraries and supports graphics library functions like graphics and text modes, read and write fonts, and bit-blit functions. It also provides extensive LCD and LED drivers, multi-channel DAC drivers, color palette activation and cursor positioning. It has a 256-color palette and is able to support up to 8-bit color depth.

The main feature of the GMA3688C is its low power consumption, which makes it suitable for most battery-powered applications. In addition, it can be used in combination with an ADC/DAC or an analog-to-digital converter. The GMA3688C gives the user the flexibility to choose the operating voltage, allowing it to be powered either from a DC power source or through the USB port.

The GMA3688C is perfect for any display project that requires a low-power, high-density, and robust display module. With its integrated image processor, easy-to-use graphics library and low power consumption, it is perfect for any small to medium size LED dot matrix, LED cluster or LCD display.
