Embodiment 1

[0045] This embodiment provides a method for testing image display quality, such as figure 1 As shown, the test method includes three steps: data import, color test and test result processing, as follows:

[0046] S101, the data import: import the color data corresponding to the 24 color blocks of the Macbeth color standard card;

[0047] Macbeth color standard card (Macbeth color chart) is the value of the color blocks in the picture qualitatively given by Microsoft, including a variety of common colors. Using the colors corresponding to the 24 color blocks of the Macbeth color chart to measure the true color of the display is closer to people's actual perception of color, and thus can better reflect the actual image display quality or color performance of the monitor.

[0048] S102, the color test: input the color data corresponding to the 24 color blocks of the Macbeth color chart into the sample to be tested, and make the sample to be tested display the monochrome picture...

Embodiment 2

[0064] Embodiments of the present invention also provide a test platform for image display quality, such as image 3 As shown, the test platform includes:

[0065] Data import module 11, for importing the color data corresponding to 24 color blocks of Macbeth color chart;

[0066] The color test module 12 is used to input the color data corresponding to the 24 color blocks of the Macbeth color chart into the sample to be tested, and make the sample to be tested display the monochrome picture corresponding to the 24 color blocks of the Macbeth color chart one by one, At the same time, a color test instrument is used to perform a color test on the monochrome picture displayed on the sample to be tested;

[0067] The test result processing module 13 is used to compare the color test result with the pre-stored reference color parameter value, and generate an evaluation document according to the comparison result.

[0068] The invention provides an automatic test platform for ima...

Abstract

The embodiment of the invention discloses an image display quality testing method, testing platform and system and relates to the display field. The image display quality testing method, testing platform and system is wide in application range and high in result accuracy and can reflect actual image display quality of a displayer. The image display quality testing method comprises the steps of importing data, namely importing color data corresponding to 24 color blocks of a Macbeth white color standard card; testing colors, namely inputting the color data corresponding to the 24 color blocks of the Macbeth white color standard card into a sample to be tested, enabling the sample to be tested to display the single-color images corresponding to the 24 color blocks of the Macbeth white color standard card one by one, and meanwhile utilizing a color analyzer to conduct color testing on the images displayed by the sample to be tested; processing test results, namely comparing the color test results with a pre-stored standard color parameter value one by one and generating an appraisal document according to comparison results.

Description

technical field [0001] The invention relates to the display field, in particular to a test method, test platform and system for image display quality. Background technique [0002] During the production process of the color display, it is necessary to use a color analyzer (color analyzer) to test and evaluate the image display quality of the color display. For RGB (red, green and blue) three-primary color products, the usual practice is as follows: make the sample to be tested (color display) display the RGB three-primary colors in turn, and use a color analyzer (color analyzer) to test the RGB three-primary color picture presented by the sample. Test to obtain the corresponding brightness and color coordinates, and then mark and connect the coordinate points corresponding to the RGB three-primary color screen in the chromaticity space. The larger the area of ​​the formed triangle area, the larger its color gamut value, and the better the image display quality. the better. ...
