In the step 9, judge whether over the manufacturing numbering of reading in a day.When being this manufacturing numbering, proceed to step 10.Make numbering not simultaneously with this, proceed to step 12.
In the step 10, identical with the manufacturing numbering of news in past one day, thereby the lamp of control box 24 is glimmered, remind the overlooker to note, when the overlooker knows this situation in step 11, the cursor key of pressing operation case 24, proceed to step 12, during not according to the pressure cursor key, return step 6, read in the step of making numbering once more.
In the step 12, the test starting key of input operation case 24 is used to start the image inspection.
In the step 13, judge whether to look into reading mode.Be to look into reading mode, then proceed to step 14, judge whether the E-EDID information that ROM18 writes in the liquid crystal display device 12 is normal because need.If not looking into reading mode, proceed to step 16.
In the step 14, read in the E-EDID information that liquid crystal display device 12 writes, judge the check of the E-EDID information that this reads in the step 15 and whether be 0 (promptly whether normal) if normal, carry out step 19.Undesired, then, proceed to step 16 because write E-EDID information again.
In the step 16, send E-EDID information, this information is write among the ROM18 of liquid crystal display device 12 from the interface arrangement of testing fixture.The E-EDID information that this writes is the E-EDID information corresponding with test data, makes numbering and writes the manufacturing numbering that bar code reader 30 reads in, and makes the current week in year that then writes timer 22 meterings in the image testing device 10 year week in real time.
In the step 17, image testing device 10 reads the E-EDID information that writes once more, and checks that in step 18 this E-EDID information of reading in is normally or unusual.For this reason, judge check read and the check that whether equals to write and, perhaps check with whether be 0.Check and equate to be at 0 o'clock is judged as and normally writes E-EDID information, and proceeds to step 19, and in addition, demonstrations that then make mistakes finishes inspection.
In the step 19, after the week in manufacturing year on the control box 24 in the current E-EDID information that reads of demonstration, carry out the normal image inspection in step 20.That is, the test data of interface arrangement to selecting the liquid crystal display device 12 transmission test datas selection steps 2 from testing fixture lighted liquid crystal display device, confirms to have or not display defect with visual or video camera.
So, carry out E-EDID information continuously with same device and write and the image inspection, thereby can simplify job step.
Be designed to confirm to write E-EDID information again and normally write fashionablely, can not enter next step, thereby can utilize programmed control to give to prevent to forget function and the checking function that writes E-EDID information.
In addition, make numbering with bar code reader 30 input after, write E-EDID information, and have the affirmation function, thereby manufacturing numbering that can input error etc.
Moreover, even for forbidding rewriteeing the liquid crystal display device 12 of E-EDID information, can judge in looking into reading mode that also the E-EDID information that writes is normally or unusually.
In the foregoing description, liquid crystal display device is illustrated, even but replace the CRT monitor part of organic EL display device or Braun tube, equally also can check that step writes E-EDID information in the same manner with image.
The various hardware of composing images testing fixture can be used as the known hardware of computer system, and can do all conversion in the scope that does not break away from main idea of the present invention.For example available single hard drive device constitutes the 1st memory storage and the 2nd memory storage.Also but appropriate combination and functions of use are different from the memory device of hard drive device and RAM etc.
