Embodiment Construction

[0043] Please refer to figure 1 , figure 1 It is a schematic diagram of a mobile device 1 according to an embodiment of the present invention. The mobile device 1 may be a mobile device conforming to a mobile industry processor interface (Mobile Industry Processor Interface, MIPI) specification, which may include a processor 11 (such as a microprocessor or an application-specific integrated circuit ASIC), a storage unit 12 , a display driver chip 10 and a panel 13 . The storage unit 12 can be any data storage device for storing a program code 120 to be accessed by the processor 11 . For example, the storage unit 12 may be a read only memory (ROM), a random access memory (RAM), an optical storage device, etc., but is not limited thereto. The display driver chip 10 can receive frame data or image packets transmitted by the processor 11 , so as to drive the panel 13 to display image frames.

Abstract

The invention discloses a data reading method, a data transmission method and a relevant mobile device. The data reading method is used for a display driving chip of a panel, and comprises the following steps that: a writing format and at least one image packet are received; a synchronizing signal is generated according to the writing format; and data of the at least one image packet is read according to the synchronizing signal, so that the panel displays the data of the at least one image packet in a video mode.

Description

technical field [0001] The present invention relates to a data reading method, a data transmission method and a related mobile device, in particular to a data reading method, a data transmission method and a related mobile device capable of reading image data in a video mode through a memoryless drive chip. Background technique [0002] The Mobile Industry Processor Interface (MIPI) is the data transmission processing interface between the processor and the display driver chip in the current mobile device. The display driver chip can receive and read the data transmitted by the processor or the transmission terminal (Host) through the mobile industry processor interface, so that the display panel can display the data screen. The mobile industry processor interface can be classified into two application modes: Video mode and Command mode. Since the transmission protocols of the two are different, different hardware designs are derived. These two modes will be determined by t...
