Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, the method for testing embodiment one of display color performance of the present invention is shown, comprise the following steps:
In test process, each test is identified at shown sharpness and the identification that goes out of display and gradually changes with respect to the user, and for example, from left to right sharpness and identification reduce gradually.The user can choose last the test sign that can see clearly according to the judgement of oneself.Wherein, each test is identified at the shown sharpness that goes out of display and identification gradually changes and can realize by the mode that test sign and the visible difference of background are dwindled with respect to the user, by the user, the color representation ability is tried to achieve in the identification of visible difference.For example, testing sign self color by change realizes or changes background color realizing.The test sign can be word, figure or color lump etc.Concrete, aforesaid background can refer to test the background at sign interface, place, being about to the test sign is placed under some color background, it can be also test sign itself, namely, adopt the color lump of color gradient as the test sign, other test signs adjacent with a certain test sign can be considered to background.
For example, be designated the word bar of gray scale gradual change as example take test, when test, the multiple color background can be set, the test sign of gray scale gradual change is set under each color background, the user can choose clearly last test sign of institute under each color background, system can draw the current color representation ability of display according to sharpness and the identification of user-selected test sign of getting.For example, for color representation ability display preferably, the user may be able to see rightmost clearly or near rightmost test sign, and for the general display of color representation ability, the test sign in the middle of the user may can only see clearly.Generally, mostly be test to gray scale and Red Green Blue for the test of display color, so, four background colors can be set in the present embodiment, that is, and ash, red, green, blue.Wherein, the sequencing of four background colors does not limit, and can determine arbitrarily.When the user is choosing the test sign under a certain color background after, automatically enter the interface of next color background, after the user had chosen test sign under all color backgrounds, system calculated the current color representation ability of display automatically according to user's selection result.Certainly, can also change according to specific needs for color background, for example, can increase other color as test.
The detailed process that draws the current color representation ability of display can be determined as required, for example, suppose to have four kinds of background colors, be respectively ash, red, green, blue, under each color background, 40 test signs are arranged, if the test that the user can see under different color backgrounds sign is respectively: grey, the 38, redness, the 35, green, the 30 and blue, the 33.Can the first-selected numerical range of determining different color representation abilities, then test result is calculated, obtain the test value under each color background, be the color representation ability of current display.
