At present, can be by the control of driver, the change driving parameters, give a piece of bad advice point (bright spot) in the use of flat-panel screens, be difficult for being found, and be the change driving parameters, must elder generation determine to have in the display panels which sub-pixel also to be indicated for bad point by the user, thereby must be detected in the display panels bad point and in addition addressing indicate, giving a piece of bad advice for driver change driving parameters a little is difficult for being found.
Become known for detecting the mechanism of display panels, see also shown in Figure 1, announce the M278900 patent as TaiWan, China, it comprises folded mutually establishing in order to drive first gear unit 2 and second gear unit 3 of image capture unit 1 displacement, this first gear unit 2 by belt teeth 4 with the drive of belt pulley 5 in two ends with moved further to drive second gear unit 3, make second gear unit, 3 transversal displacements, yet this kind mode, when skidding between belt teeth 4 and the belt pulley 5, promptly can cause second gear unit 3 to rotate, thereby the position of image capture unit 1 promptly can distortion, it can influence the precision of detection and location, when being particularly useful for detecting the display panels of big molded dimension, increase the weight of its influence because dimension and weight increases, can't ignore the influence that it causes.
The utility model content
Therefore, fundamental purpose of the present utility model is to disclose the bad point location of a kind of flat display panel testing agency, and it does not have the problem of transmission slip, and can increase the precision of detection and location.
Via as can be known above, for achieving the above object, the utility model is the bad point location of an a kind of flat display panel testing agency, be used for the test liquid LCD panel, it comprises image capture unit, first linear displacement apparatus and second linear displacement apparatus, wherein this image capture unit is used to show the local sub-pixel of this display panels, this first linear displacement apparatus is taken advantage of and is carried this image capture unit linear displacement, and this first linear displacement apparatus is provided with first detecing element of this position of image capture device of perception.
This second linear displacement apparatus comprises first support and second support that relative spacing one distance is provided with, this first support and this second support set up the first linear electric machine mobile device and the second linear electric machine mobile device that is driven by same driver separately, the two ends linear displacement that this first linear electric machine mobile device and this second linear electric machine mobile device carry this first linear displacement apparatus respectively, this second linear displacement apparatus is provided with second detecing element of this first linear displacement apparatus position of perception, and this second linear displacement apparatus and this first linear displacement apparatus fold an angle.
In view of the above, this driver drives this first linear electric machine mobile device and this second linear electric machine mobile device simultaneously to drive this first linear displacement apparatus displacement, therefore can guarantee that this first linear electric machine mobile device is identical with the displacement of this second linear electric machine mobile device, and allow this first linear displacement apparatus not have the doubt of rotation, compare known technology, it can increase the precision of detection and location.
