Problems solved by technology

[0003] However, the existing solutions using a single display driver are limited by the size of the integrated circuit, resulting in the inability to configure a large number of data drive channels, which in turn has the disadvantage of being unable to support higher resolution display panels

Embodiment Construction

[0021] The display driving system of the embodiment of the present invention uses a plurality of display drivers to drive the display panel, wherein each display driver is correspondingly configured with a virtual channel (Virtual Channel) value for addressing.

[0022] Please refer to figure 1 , which is a block diagram of a display applying the display driving system according to an embodiment of the present invention. The display 1 includes a display driving system 10 and a display panel 20 , wherein the display panel 20 includes n panel sections A1 , A2 , . . . , An, where n is a natural number greater than 1. For example, each of the n panel partitions A1-An corresponds to substantially the same area and resolution. Taking an example where n is equal to 3 and the display panel 20 has a resolution of 1920×1080, each of the n panel partitions A1 - A3 has a resolution of 640×1080 correspondingly.

[0023] The display driving system 10 includes a main controller 100 and n d...

Abstract

A data transmission method is applied in a display which comprises a display panel and includes steps of providing a main controller and n display drivers; providing a mobile industry processor interface (MIPI) communication link to connect with the main controller and the n display driver; respectively determining n virtual channel values Vc1-Vcn corresponding to the n display drivers; applying the main controller to provide control commands with parameters of virtual channels via the MIPI communication link; when the parameters of the virtual channels correspond to the ith virtual channel value Vci, subjecting the ith display driver to responding to the control commands to execute corresponding operation, and subjecting the rest n-1 display drivers to give up the control commands, wherein the n is a natural number larger than 1, and the i is a natural number smaller than or equal to n.

Description

technical field [0001] The present invention relates to a data transmission method and a display driving system using it, and in particular to a data transmission method applied to a mobile industry processor interface (Mobile Industry Processor Interface, MIPI) communication link and its application display driver system. Background technique [0002] In today's era of rapid technological development, small and medium-sized displays have been widely used in various electronic products, such as mobile phones, personal digital assistants (Personal Digital Assistant, PDA), multimedia players, and satellite navigation machines. Generally speaking, a single display driver is usually used for small and medium-sized displays to perform scan-driven and data-driven operations on the display panel. [0003] However, the existing solution using a single display driver has the disadvantage of being unable to configure a large number of data driving channels due to the limitation of th...
