Description of the new model: [Technical field to which the new model belongs] The new model relates to a tester, especially a flat display panel tester with a precise positioning unit. ^ [Previous technology] In recent years, liquid crystal displays (LCDs), plasma displays, or organic electroluminescence displays (〇LEDs) have gradually replaced traditional cathode-ray tubes (CRTs) due to their high image quality, light weight, and no radiation. ) Display becomes a star industry. Generally speaking, during the production process of a flat display panel (FlatPanel), it is necessary to undergo optical testing. The phase and each unit cell can be correctly illuminated according to the input signal. It should emit light, whether it is a dark spot that fails to emit light when the drive signal is input,戋 is a bright point that has been short-circuited and emits light without inputting a signal, and is called a so-called bad point = In addition, 'If a unit cell of a row or column is restricted by the signal line or the disconnection of the line, it may also cause a continuous section of the line. dark. The number of the above-mentioned dead pixels also determines the production level and price of the display panel. > Among the above-mentioned defects, the presence of bright spots in the dark field where the display panel should be completely free of signals is the most abrupt. Therefore, during the testing process, the position of the aforementioned bad point or the starting line of the bad line should be accurately found for subsequent follow-up, such as laser marking of the puppet point to a dark point, or welding of a broken line segment from the puppet point to a short circuit. The unit cell in the center of the line segment can still operate normally for repair processes. In the current addressing method, a more accurate method is to pass-a test machine with a price of more than 10 million yuan, and at the same time use a plurality of electrodes to connect to each row of the display panel, the column signal line and the gate electrode position, and input the enable signal From this, the response data of each unit cell on the Aberdeen panel is obtained simultaneously, so as to find all bright / 5 • M278900 dark spots. Although this method is fast and accurate, it is quite inadequate for low-cost merchants with a low number of tests: For the new type ... 922_ 号 拍 顾 _ 44 > Construct a digital camera, and gradually use the image of ^^^, and then use software to gradually analyze and identify each-= middle = set. This method not only consumes a large number of cells, but it is smaller than the crystal. Cell size and position accuracy are not ideal, which also leads to the possibility of misjudgment. If a good cell is mistakenly judged as a bad point, it will increase the number of failures and unnecessarily degrade the quality of the display panel. " Bad spot [New content] Therefore, the purpose of this new model is to provide a flat display panel detector for a purely dense positioning unit that can accurately locate the dead spot. Another object of the new model is to provide an inexpensive flat panel tester. '' Thus, the new flat display panel detector W with a precise positioning unit, a base, a plurality of first transmission positioning devices spaced along the -th direction, and a first transmission positioning device connected to the first transmission positioning device along the -second direction. A second transmission positioning device, an image capturing device and a control device installed on the second transmission positioning device. The second transmission positioning device moves in the first direction relative to the first transmission positioning device, and the position of the second transmission positioning device in the first direction is measured by the first transmission positioning device, wherein the first direction and the second direction are clamped. At an angle, the image capture device moves relative to the second transmission direction, and is measured by the second transmission positioning device: M278900 The position of one direction 'control device receives the position of the transmission positioning device, and follows the second direction The position signal compensates the image capturing device in the -direction ^ position.

The first transmission positioning device 3 is connected to the slider in a second direction 30. The second direction—direction 30 and an angle between the second direction and the second direction—are driven by the second transmission positioning device = the straw slide 2U. Moved in one direction 20 and measured by the first positioning unit 22 in the first direction 20. The second transmission positioning device 3 has a second transmission unit 31 and a measurement second transmission unit 31 in the second direction. 30。 Second positioning unit 32. The second transmission unit 31 has a slide seat, a screw 3U, a transmission block screwed with a screw 312, and a bearing seat 314. The slide seat 311 can be moved in the second direction by a sliding mechanism provided on the base 1. 30 sliding, because the components and detailed operation methods of the transmission units 21, 31 are well known to skilled artisans, and this type of transmission device that can be moved along the plane has been widely used in various processing, loading and measuring machines, so I will not repeat them here. Similarly, the K-th stand unit 32 is described in this example by taking an optical ruler as an example, and it is not limited to this. In particular, in the ideal design, the first direction 20 and the second direction 30 are orthogonal. However, in actual operation, the first direction 20 and the second direction 30 are not orthogonal, but have a small angle of 8 M278900. : Since it is not absolutely orthogonal, there is an error in the position measured by the two parallel " bit units 22 when measuring. How to make this error smaller is one of the purposes of this new model. 2. The image extraction device 4 is installed on the sliding seat 3m of the second transmission material 31 and drives the premature cymbals 21 and 31. In addition to being able to move in the first direction 20, it can also be relatively opposite to the slide rail 315 in the second direction. 30. Moved by the second positioning unit 32 = the position of the video capture device 4 in the second direction%. In this embodiment, the shirt image manipulation device 4 is a thunder and light: A coupler in a person. CCD), the image capture device faces the flat display panel 10, moves to the base 1 by the transmission unit 21, and can capture the shirt image of the display area of the flat-I ▼ moving phase display panel, Preferably, the neighboring image # fetching device 4 胄 assists the use of the aligned light source 6. The control device 5 which is equipped with an assistive device-calculating unit (not shown) receives the position of the imaging green device 4 in the first direction 20 from the positioning unit 22 in the first position, the positioning unit 22, and 箆 — A? And set 4 in the first-early 32th measurement image capture and install 4 in the first direction 30 position, batch calculation single 亓 MH Tian Wei system early Wu 5 receives the position signal and after processing the early 70 ㈣ different processing axis Set as compensation or adjust output. In addition, when the image capturing device 4 is moved by using the electric motor to drive the positioning units 21 and 31 in the first direction 20 position, the image capturing device 4 can be controlled relative to the flat display panel through control. Refer to Figure 3 for the movement coordination. The description of the address compensation method is as follows: The image capture device 4 is returned to the flat display panel Η), that is, first: ~ The image capture device 4 is displayed relative to the plane, and the image fresh device 4 is displayed. The coordinates along the position of 帛 followed by the second direction 20 and the second direction 30 are moved to the vicinity of the DM278900 dead point, so that the dead point enters the visible range of the image capture device 4, and then fine adjustment and image processing are performed so that the dead point is located in the range. In the center, the control device 5 receives the individual signals of the two optical rulers measuring the position 20 of the first transmission unit 21 in the first direction, and measures the second transmission unit 31 in the first direction. The signal of the 30-position optical ruler, because the image capture device * is installed on the slide 311 of the second transmission unit 31 and follows the transmission units 21 and 31. Therefore, the position signal of the optical ruler can indirectly represent the image acquisition device 4 The displacement from the initial reference position to the position of the dead pixel with respect to the flat display panel 10, that is, the coordinates of the dead pixel with respect to the flat display panel 10 can be represented by the position of the image capturing device 4. Here, Flat display The end point of the lower-left corner of the panel is the starting reference coordinate (〇, 〇) as an example, and the displacement of the optical ruler along the slide 2m is Xi and X2, and the displacement of the optical ruler along the slide 311 is Y! The length between the two first transmission units 21 in the second direction 30 is I. In particular, it is explained that in practice, the second transmission unit 31 is connected to the carriage 211 approximately orthogonally, but it is not Absolutely orthogonal, so that & is not equal to X2 and the position coordinates of the bad point are between Xι and & and there is an error & -X !, it is necessary to further compensate the positioning to reduce the error. The compensation method is to use similar triangles and other proportions. The principle of the concept is combined with the position signal in the second direction 30. The position signal of the optical ruler is processed by the arithmetic unit to output the compensation distance D. Among them, X! + D is the image capturing device 4 in the first direction 20 Position on the make up. Take the 5-pair panel of one pixel (pixelei) specification 1024 parent 768 as an example, using this new type of detector can make the error as small as 1.5 sun-pixel ~ 1 pixel. In summary, 'The new flat display panel inspection instrument with precision positioning device 10 M278900 measuring instrument uses the position of the image capture device 4 in the first direction 20 and the second direction 30.' , Further to the position coordinates of the image capturing device 4 in the first direction 20, so that the error of the displacement amount can reach about 1.5 sub pixel, so that the detection of the dead pixels has a higher accuracy, in addition, 'simple components and clever matching It is not only cheap to use, but also easy to use.
