Embodiment
For detector probe and the contact in binding district, and improve the accuracy of pressure detection, reduce and detect operation easier, embodiments provide a kind of circuit checker.For making the object, technical solutions and advantages of the present invention clearly, by the following examples the present invention is described in further detail.
As depicted in figs. 1 and 2, the circuit checker that one embodiment of the invention provides, comprises pressure head 1 and display device 2, wherein:
The first surface 1a of pressure head 1 be provided with pressure transducer 5 with for binding with display panel the probe 4 that district 3 contacts conducting, first surface 1a to be pressure head 1 with display panel bind surface that district 3 contacts;
Display device 2 is connected with pressure transducer 5, for showing the pressure detection data of pressure transducer 5.
Circuit checker to the principle that display panel binding district 3 carries out electric circuit inspection is: after pressure head 1 and display panel bind district 3 contraposition, probe on pressure head 1 and display panel are bound district 3 and are contacted conducting, thus display panel is bound the circuit turn-on in district 3, make Signal transmissions to display panel 8.If pressure head 1 pair of display panel binding district 3 applied pressure is excessive, then can have influence on the normal display of display frame, if and pressure head 1 pair of display panel binding district 3 applied pressure is too small, probe 4 and display panel then can be caused again to bind district 3 loose contact, Signal transmissions is unstable, and display frame produced secretly, brightness irregularities etc. is bad.Therefore, the detection of the contact in district 3 bound to probe 4 and display panel very important.
In the technical scheme of the embodiment of the present invention, pressure head 1 and display panel are bound the surface that district 3 contacts and are provided with pressure transducer 5, after pressure head 1 and display panel bind district 3 contraposition, display device 2 can demonstrate the pressure detection data of pressure transducer 5 in real time, therefore can monitor the contact that probe 4 and display panel bind district 3 in real time, adopt the mode of pressure-sensitive paper compared to existing technology, the accuracy of detection is high, easy and simple to handle, and testing cost reduces.
As depicted in figs. 1 and 2, in the preferred embodiment of the present invention, circuit checker also comprises the pressure regulating part 6 of the second surface 1b being arranged on pressure head 1, second surface 1b is the surface of pressure head 1 away from display panel binding district 3, and pressure regulating part 6 is for regulating the pressure in pressure head 1 pair of display panel binding district 3.By regulating pressure regulating part 6, the pressure that can adjust pressure head 1 pair of display panel binding district 3 is in the scope of application, thus makes probe 4 and display panel bind district 3 good contact conducting, and can not have influence on the normal display of display frame.
The specific constructive form of pressure regulating part 6 is not limit, as shown in Figure 2, in this specific embodiment, circuit checker also comprises pedestal 7, pedestal 7 comprises main body 71 and teat 72, pressure head 1 slidable fit is in main body 71, and pressure regulating part 6 is with teat 72 thread connection and the bolt that can abut with the second surface 1b of pressure head 1.Can be regulated the pressure in pressure head 1 pair of display panel binding district 3 by the nut screwing bolt forward or backwards, this is simple and reliable for structure, regulates very convenient.
