Analysis
The Y300 incorporates a 4.0-inch TFT LCD with a resolution of 800 x 480 pixels.
The Y300's LCD uses the Mobile Industry Processor Interface (MIPI), requiring only two
pairs of differential signaling cables and one pair of power cables. The LCD interface
supports 60 Hz refresh rate, provides the frame synchronization function, and uses GPIO_97's
MDP_VSYNC as the data transmission synchronization signal to protect the LCD from being
cracked.
