Embodiment Construction

[0024] This embodiment proposes a miniature low-voltage differential signal (mini-Low Voltage DifferentialSignal, mini-LVDS) interface unit, which can support mini-LVDS through a smaller first-in-first-out (FIFO) register. Interface different output configurations.

[0025] Please refer to FIG. 1 , which shows a block diagram of a miniature low voltage differential signal interface unit applying this embodiment. The mini-LVDS interface unit 10 is applied in a display panel driving circuit 10, for example, the display panel driving circuit 10 is applied in a display system (not shown). The display panel driving circuit 10 is used to receive image data from an image data source, and output corresponding analog data Sa1 ˜ SaN to the display panel 20 to display corresponding images, where N is an integer greater than 1.

[0026] The display panel 20 includes a pixel array (not shown), wherein each pixel includes N sub-pixels, for example. The image data Sd1˜SdN input to the mini...

Abstract

The invention relates to a data access device and a data access method, in particular to a data access device and a data access method for accessing a first in first out (FIFO) memory of a signal transmission interface capable of supporting a mini-low voltage differential signal (mini-LVDS). The data access device comprises a first in first out (FIFO) memory used for storing image data and a controller used for accessing the first in first out memory by an annular way, wherein the controller writes the image data into the first in first out memory on a pixel basis and reads the image data in the first in first out memory on a channel basis.

Description

technical field [0001] The present invention relates to a data access device and method, in particular to a first-in-first-out (FIFO) that can support a miniature low voltage differential signal (mini-Low Voltage Differential Signal, mini-LVDS) signal transmission interface. Out, FIFO) register (memory) data access device and method. Background technique [0002] In today's era of rapid technological development, the pursuit of high-resolution displays is a market trend. In order to meet the high data transmission bandwidth requirements corresponding to high-resolution specifications, data transmission interfaces, such as micro-low voltage differential signals ( The mini-Low Voltage Differential Signal (mini-LVDS) interface already exists to provide higher bandwidth requirements for data transmission. [0003] The micro-low voltage differential signal interface is a high-speed serial transmission that can support 3-channel, 4-channel, 5-channel or 6-channel data output conf...
