The MIPI interface of the LCD has D1N,D1P definition, this is the D1N\/P Data channel, as the host transmits data to the LCD driver IC, the polarity of the Data lane1 channel is different, there are positive and negative two poles.

An LCD is a flat panel display or other electronically modulated optical device that uses the light modulation properties of a liquid crystal in combination with a polarizer. Liquid crystals do not emit light directly, but use backlights or reflectors to produce colored or monochromatic images. LCDS can be used to display arbitrary images (such as general-purpose computer monitors) or fixed images with low information content, which can be displayed or hidden. For example: pre-set word, number, and seven-segment displays, such as digital clocks, are good examples of devices with these displays.
