HX8258-A is a 1200/1026-channel outputs source driver with TCON， and 3-wire Serial Port Interface. It also supports 3-chip cascade mode to extend source channel to be 3072 channels （resolution： 1024RGB x 768）。 The interface follows digital 24-bit parallel RGB input format. The TCON generates the 400x240， 800x480， 800x600， 1024x600 and 1024x768 resolutions and provides horizontal and vertical control timing to source driver and gate driver. It also supports dithering feature， apply source driver with 6-bit DAC to perform 8-bit resolution 256 gray scales. The source driver receives 6-bit by 3 dots of digital display data per clock from TCON and generates corresponding 64-level gray scale voltage output. Since the output circuit of this source driver incorporates an operational amplifier with low power dissipation， and performs wide voltage supply range and small output deviation. Therefore， a high quality display with less crosstalk can be achieved
