7 Inch Cm/HS LCD Module with Driver Board for Video Door Phone

7 Inch Cm/HS LCD Module with Driver Board for Video Door Phone

​The LCD driver board is interconnected with the MCU using a parallel bus. The bus width is 8 bits. For the MCU data below 8BIT/pixel, you can choose to use a standard color palette. The graphics card provides the MCU with a virtual memory corresponding to the pixels of the display, and all the display data of the MCU only operates on the "virtual memory".

The LCD driver board is interconnected with the MCU using a parallel bus. The bus width is 8 bits. For the MCU data below 8BIT/pixel, you can choose to use a standard color palette. The graphics card provides the MCU with a virtual memory corresponding to the pixels of the display, and all the display data of the MCU only operates on the "virtual memory". The MCU can update the data of the virtual video memory to the real video memory at any time, which is convenient for control. The advanced video memory management mechanism is adopted internally, which prevents the flickering and screen jumping that occur in the display control of various chips.
