It consists of 240 source line and 320 gate line driving circuits. The resolution of this LCD is 240 (H) RGB x 240(V), it supports horizontal mode and vertical mode, and it doesn't use all the RAM of the controller. This LCD accepts 8-bits/9-bits/16-bits/18-bits parallel interface, that are RGB444, RGB565, RGB666. The color format used in demo codes is RGB565. This LCD use a 4-line SPI interface for reducing GPIO and fast speed.LCD
