After the gain of correction signal amplifier 12, computer 32 can start to carry out feature measurement via test command CMD indication microcontroller 20, for example tests the reaction velocity that display panel 28 switches between the first GTG and the second GTG.Microcontroller 20 can send corresponding steering order SC to display controller 30, make the display panel 28 periodically test pictures of Alternation Display the first GTG and the test pictures of the second GTG, and when each switch test picture to microcontroller 20 passback one look-at-me SQ.When display panel 28 shows test pictures, each OPTICAL SENSORS K[n] also measured.According to look-at-me SQ, microcontroller 20 can with the timing synchronization of Picture switch, control according to this switching of multiplexer 22 and the output of reaction signal S0, and collect signal S2 according to the sequential of Picture switch, to integrate out measurement result S3.Measurement result S3 can be back to computer 32; Having obtained enough measurement results if the testing tool formula of computer 32 is judged, just can send another test command CMD, is for example the reaction velocity that test display panel 28 switches between the 3rd GTG and the 4th GTG.According to this test command CMD, microcontroller 20 can send another steering order SC, allows display controller 30 change and makes display panel 28 periodically repeatedly switch the test pictures that shows the 3rd GTG and the 4th GTG.
Due to the microcontroller 20 of measuring appliance 10, as long as just can make display controller 30 automatically according to the cycle switching of appointment, provide a plurality of different test pictures with single steering order SC, measuring appliance 10 is applicable to the display panel test of Gao Gengxin rate.The display controller 30 of Gao Gengxin rate because the display panel of Gao Gengxin rate 28 can be arranged in pairs or groups, and the functions of Gao Gengxin rate display controller 30 itself are exactly will coordinate the display panel 28 of Gao Gengxin rate and high frequency, picture data at a high speed are provided, therefore display controller 30 natural energies provide the test pictures data of quick switching according to the Gao Gengxin rate; Relatively, just need do not provided by the microcontroller 20 of measuring appliance 10 the test pictures data of high frequency, Gao Gengxin rate yet.So, the cost of measuring appliance 10 just can reduce.Display controller 30 can be carried out suitable firmware to understand and to carry out the steering order SC of microcontroller 20.
Moreover measuring appliance 10 can effectively integrate " display panel control " and " picture quality measurement " these two keys; Display panel is controlled and can be reached via steering order SC, and picture quality is measured and can synchronously be integrated according to look-at-me SQ.Via the test command of computer 32, the feature measurement of display panel can robotization, reduces tester's manpower burden, promotes the overall efficiency of display panel test.
