The FPGA based Flicker picture component generation method comprises 1, confirming horizontal perpendicular points of a Flicker picture lattice in a host computer, confirming picture vertex coordinates and coloring the points; 2, enabling the host computer to transmit the points, the vertex coordinates, color of the points and the module resolution to a data analysis module to be analyzed; 3, enabling the data analysis module to transmit analyzed data to an image signal generator; 4, writing color into a RAM (Random Access Memory) of the image signal generator with the number of pixel points of the picture lattice being served as an address; 5, scanning areas which are corresponding to pictures inside the image signal generator and calculating the every pixel point address being mapped in the picture lattice inside the scanning area; 6, reading color values of the pixel points of the picture lattice and coloring the pixel points with the pixel point addresses mapping in the lattice to be RAM reading addresses. The FPGA based Flicker picture component generation method can generate complex logic pictures such as the Flick picture by utilizing the FPGA.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal module testing, in particular to a method for generating Flicker (flicker) picture components based on FPGA (Field-Programmable Gate Array, ie Field Programmable Gate Array). Background technique [0002] With the increasing popularity of home theaters, large-screen, high-resolution liquid crystal displays have gradually become the mainstream. In the production process of liquid crystal displays, they need to be detected by picture signal generators. [0003] The traditional picture signal generator uses bmp (Bitmap) image as the image source. When testing large-screen and high-resolution liquid crystal displays, the corresponding bmp image has a large amount of data, which requires high hardware requirements for the signal generator. The picture is not smooth. Under the premise of not increasing the hardware cost, FPGA (based on the hardware structure of FPGA to generate picture d...

[0003] The traditional picture signal generator uses bmp (Bitmap) image as the image source. When testing large-screen and high-resolution liquid crystal displays, the corresponding bmp image has a large amount of data, which requires high hardware requirements for the signal generator. The picture is not smooth

Under the premise of not increasing the hardware cost, FPGA (based on the hardware structure of FPGA to generate picture data such as figure 1 As shown, it includes host computer, human-computer interaction module, data analysis module, image signal generator, synchronous dynamic random access memory, synchronous dynamic random access memory controller and image output encoding module, wherein, data analysis module, image signal generator, synchronous DRAM, synchronous DRAM controller and image output encoding module are internal components of FPGA) to generate picture data, that is, logic picture to replace part of bmp image, but it is limited to produce the simplest logic picture (such as horizontal gradient image, rectangle frame image, rectangle fill image and other images with fixed styles), so there is a problem of insufficient detection of liquid crystal display

At present, it is not possible to use FPGA to generate complex logic screens such as Flicker components.
