摘要： Provided is a high-resolution display driving system without a new design of interfaces between a timing controller and DDIs, particularly, without an entire change of a DAC unit having a role of determining gradation representation of DDIs and offsets between channels. The high-resolution display driving system includes a timing controller and a DDI unit. The timing controller generates a differential clock signal and differential data. The DDI unit generates a plurality of converted signals corresponding to the differential data in response to an operation instructing signal, a reset/enable signal, and the differential clock signal. A scheme of data transmission from the timing controller to the DDI unit is at least one of a multi-drop scheme and an m-LVDS (mini low voltage differential signaling) scheme.
