Working Principle

UEZGUI-4088-43WQH-BA integrates the HDD4088 LCD driver mounted on the MCU and connects with the LCD to realize the control function of the LCD and the display of the signal data.

The CPU communicates with the outside world through the I2C and SPI interface. The HDD4088 is used to drive the LCD to achieve the desired display effect. In addition, the powered-up RAM is used to store the imaging data required by the LCD. This module mainly consists of a CPU (Cortex-M4 MCU) and a HDD4088 LCD driver. Generally, the CPU can independently control the LCD display, and can also receive data from the LCD to achieve data processing.

First, the CPU sends activation signals to the RAM and LCD driver to initiate the initialization process. Then the CPU sends data to the RAM, and the data is stored in the RAM, and then the contents of the RAM are read out and output to the LCD through the LCD driver. The LCD gets the imaging data from the RAM and displays the required images on the LCD.

In this way, the CPU can receive real-time information from the external world, and can also achieve the control of the LCD to display relevant data. This complete process forms UEZGUI-4088-43WQH-BA’s application field and working principle.
