Abstract
The invention relates to a method for testing liquid crystal diapsly. The LCD is tested in automatic circulating mode by using multi-frames of picture whose parameter, option selected, switching the frame and changing colors displayed are set up from an inputting device. Testing personnel can make the selecting and setting based on different needs of varied frames, Thus the invented method provides features of easy to test, rich in testing picture, adjusting multi-parameters conveniently and visually.
Description
The present invention relates to the method for testing of LCD.
Test method for liquid crystal display in the past only provides single test pictures, such as once testing frame line drawing face in the test, want to continue the test grey menu and then must withdraw from test procedure last time, start new test procedure, therefore can not in once testing, finish the test of a plurality of pictures.And the various parameters of test pictures also are that program has been fixed, the test color is single, the grey menu of every kind of color has only 32 kinds of color stratum at most, this makes that the picture adjustment is inconvenient or can't adjust at all that each test pictures can't be done freely to switch and automatic cycle testing according to tester's needs.
The purpose of this invention is to provide the tester and once finish the test of a plurality of pictures in the test, and can allow each picture freely switch and do the test method for liquid crystal display of automatic cycle testing.
To achieve these goals, the a plurality of pictures of test method for liquid crystal display of the present invention are provided with the program setting shelves, selection or setting by the parameter on the program setting shelves, change display frame and Show Color thereof, and freely switch in each picture intercropping, a plurality of pictures are made automatic cycle testing.
After adopting such scheme, the tester can make one's options according to the different needs of different pictures or set, and makes that test is comparatively convenient, and test pictures is abundanter; Because each picture is provided with the adjustment of multiple parameter, make that adjustment is convenient and intuitive again; And according to the option of selecting, each picture is automatic cycle testing in regular turn.
The present invention is further detailed explanation with concrete preferred forms below in conjunction with accompanying drawing.
Fig. 1 is the process flow diagram of test method for liquid crystal display of the present invention.
Fig. 2 is menu 1 option of test method for liquid crystal display of the present invention.
Fig. 3 is menu 2 options of test method for liquid crystal display of the present invention.
Fig. 1 discloses the program step for an algorithm finishing the object of the invention.After setting up procedure 10, processor is carried out determining step 11, to judge whether the entering program setting shelves, whether presses right mouse button for the tester in the present embodiment.If judge it is sure, then enter step 13, that is enter the program setting shelves of test procedure, eject a shortcut menu 1 in test pictures, test according to selected test pictures on the menu 1.Option on the menu 1 as shown in Figure 2, it comprises following options: picture and selecting; Automatic cycle testing is selected; Frame line drawing face; The pure color picture; Normal video graphic array (VGA) 16 look pictures; Grey menu; Chequered with black and white vertical bar picture; Chequered with black and white horizontal stripe picture; Other true color picture.The pure color picture comprises redness, green, blueness, white and other pure color picture.Grey menu comprises redness, green, white, blend color grey menu, other color grey menu.Wherein " the blend color grey menu " is meant that redness, green and white grey menu are presented on the same test pictures independently of each other." " Xiang Shihui ejects a shortcut menu 2 to picture and selecting in selection.Not only be provided with 16 kinds of test pictures on the menu 1 on the menu 2, and select the different test pictures above this, also can increase corresponding function on the menu 2.When select " frame line drawing face ", " red picture ", " blue picture ", " white picture " and the time, have additional timer on the shortcut menu 2, can set picture according to the needs of test and show the time.Select " other pure color picture " time, on the shortcut menu 2 except having additional timer, also set up the color settings item, can drag the scroll bar of three kinds of colors of red, green, blue respectively, select the blending constituent ratio of three kinds of colors of red, green, blue, wherein every kind of color can be carried out the selection of 256 kinds of different tones.This menu 2 as shown in Figure 3.Select " red grey menu ", " blue grey menu ", " white grey menu " time, shortcut menu 2 is except having additional timer, also set up grid number setting option, can the grid number of picture be provided with by the scroll bar that drags grid number setting option.Select " other color grey menu ", " chequered with black and white vertical bar picture ", " chequered with black and white horizontal stripe picture ", " other true color picture " time, have additional timer, grid number setting option on the shortcut menu 2.If judging whether of step 11 is fixed, then enter step 12, the tester does test one by one by left mouse button to above-mentioned 16 pictures.But the tester can press the right button of mouse at any time on each test pictures, enters step 11.If desired 16 pictures are made automatic cycle testing, then on the choice menus 1 corresponding Automatic Cycle option (Auto cycledisplay).
After test finishes, press [Esc] key, or withdraw from option (Exit) on the choice menus 1, withdraw from test procedure.
Most preferred embodiment of the present invention is illustrated, and various impartial variation or the remodeling made by those of ordinary skills can not break away from application range of the present invention.
