Embodiment Construction

[0023] The present invention proposes a data transmission interface method, which uses direct current (DC) level extraction and conversion as the method of alternating current (AC) level, and uses limited data lines to create more data bits that can be captured, so that the data can be transmitted The larger the quantity, the more data lines are saved, the smaller the space occupied, and the lower the cost.

[0024] For the method of this data transfer interface, please refer to figure 2 , which shows a schematic diagram of the timing sequence of DC and AC voltage levels during data transmission in a data transmission interface method according to a preferred embodiment of the present invention. Such as figure 2 In the low-swing differential signal (RSDS) transmission method shown, the signal voltage originally used to transmit 2-bit data is based on the signal voltage, and the transmission voltage level of the 2-bit data can be used to swing out 3-bit data. Data, that is ...

Abstract

An interfacing method of data transmission includes utilizing DC quasibit conversion to generate AC quasibit for catching more files, using two pairs of file line to have two sets of DC quasibit for generating the third bit of file and using four pairs of file line to have four sets of DC quasibit for generating seven bits of file in interlacing way, doing this for rest file lines to achieve that the more file transmitted, the more file line saved as well as the less space occupied.

Description

technical field [0001] The present invention relates to a data transmission interface method, and in particular to a differential signal data transmission interface method. Background technique [0002] In recent years, liquid crystal display panels have gradually become the mainstream of display panels due to their advantages of light weight, thin size, large or small area, low operating voltage, power saving, and no radiation. In particular, for portable electronic devices, such as screens of notebook computers, mobile phones, displays of Personal Digital Assistants (Personal Digital Assistance, "PDA"), etc., only liquid crystal screens can meet their needs. The technology of the liquid crystal display panel and its required data transmission interface has become more and more important. [0003] The data transmission interface of the traditional thin film transistor liquid crystal display is more commonly used in the transmission method of Reduced Swing Differential Sign...
