Embodiment Construction

[0043] see figure 2 , figure 2 A schematic diagram of the data transmission structure 3 according to the first specific embodiment of the present invention is shown. The data transmission structure 3 of this embodiment can be used in a source driver circuit (source driver circuit) of a display device, such as figure 2 As shown, the data transmission structure 3 includes a plurality of data channels 30 . In practical applications, each data channel 30 corresponds to at least one set of subsequent load circuits (for example, at least one scan line on a display device). In this example, a single data channel 30 is time-division multiplexed to correspond to two scan lines on the display device for illustration, but the present invention is not limited thereto.

[0044] Such as figure 2 As shown, in this embodiment, each data channel 30 may include a first latch L1 , a second latch L2 , a third latch L3 and a fourth latch L4 . The first latch L1 , the second latch L2 , the...

Abstract

The invention discloses a data transmission structure and a data transmission method. The data transmission structure comprises an input buffer layer and an output buffer layer, wherein the input buffer layer comprises N input latches which are connected in series in turn; a first input latch in the input buffer layer is coupled to a data module; the output buffer layer comprises N output latches which are connected in series in turn; and a first output latch in the output buffer layer is coupled to an Nth input latch of the input buffer layer. When the input buffer layer is opened, data in the data module is read into the input buffer layer in turn, the data in the input latches is transmitted to the output latches in the output buffer layer in turn, and the data is transmitted to the Nth output latch of the output buffer layer in turn and is further output by the Nth output latch.

Description

technical field [0001] The invention relates to a data transmission method and a data transmission structure, in particular to a data transmission method and a data transmission structure that can be used in a source drive circuit. Background technique [0002] With the continuous development of electronic display technology, various thin panel displays have become the main multimedia image carriers in life, such as thin film transistor liquid crystal display (TFT-LCD) and active matrix organic light emitting diode (OLED) Active matrix organic light emitting diode (AMOLED) display has gradually become a common electronic display device in homes, companies or various applications. [0003] In order for the display device to accurately and real-time play image information, the driving circuit in the display device is very important. The driving circuit is used to pre-read each scanning line into the temporary buffer corresponding to each scanning line, and then sequentially l...
