Abstract:
1. An intra-system interface unit in a flat panel display, comprising: a control IC unit and a driving IC unit, the control IC unit receiving an image signal data output externally and compressing and processing the image signal data, and sending the image signal data to the driving IC unit through an interface therebetween, and the data being decompressed within the driving IC unit and then output, wherein the control IC unit comprises: a signal receiver that receives the image signal data output externally, and decodes the image signal data to resolve the image signal data into a logic signal that can be processed within the control IC unit; a gray level data classifier that receives the image signal data sent by the signal receiver, wherein each pixel point in the flat panel display includes a red sub-pixel point, a green sub-pixel point and a blue sub-pixel point, and the image signal data of a pixel point includes gray level data of the red sub-pixel point, gray level data of the green sub-pixel point, and gray level data of the blue sub-pixel point, the gray level data classifier further classifies respective sub-pixel points in a row on the flat panel display in accordance with gray level data of the respective sub-pixel points, and groups addresses of one or more of the sub-pixel points in the row that have a same gray level into one group; a data and address encoder that receives data sent by the gray level data classifier, for the image signal data of each row, firstly address-encodes the respective sub-pixel points in the row such that each sub-pixel point has a unique address code, and then combines each gray level data in the row and address codes corresponding to the sub-pixel points having the gray level data together for being mixed-encoded to form an information code to be sent, the information code containing the gray level data and corresponding sub-pixel address code; and a differential signal sender that receives the information code sent from the data and address encoder, converts the information code to a differential signal according to a certain rule, and sends the information code through the interface to the driving IC unit, where the information code is decompressed and then output.
