Description

TECHNICAL FIELD

[0001] The utility model mainly relates to screen detection technical field, concretely relates to a scratchproof four-probe resistance meter joint. BACKGROUND

[0002] At present, the market demands a large number of production liquid crystal panels, and there is an important process in the thinning process, which is a coating process, and the most important special feature of the coating process is resistance value, which is 100% to ensure that all products are coated and the resistance value is normal, after the coating production is finished, all products need to be measured, and resistance measurement needs to use four-probe resistance meter.

[0003] In the current resistance detection, since the probe of the four-probe resistance meter has a small contact area with the screen, if the staff presses too hard during detection, it will cause a slight scratch on the screen, and thus reduce the quality of the screen, therefore, the detection personnel generally detects the resistance in the invalid area of the screen edge, so that even if it is scratched, it will not cause quality problems in the subsequent screen.

[0004] The inventor found the following defects in the specific embodiment operation process:

[0005] In order to prevent scratches during four-probe resistance meter measurement, the four-probe resistance meter probe position is improved, the resistance meter does not contact the in-plane during measurement through the limiting block of the resistance meter periphery, the contact points are all in the invalid area position of the substrate, avoiding the contact with the effective area position of the cell glass, achieving the purpose of preventing scratches, reducing the risk of scratches during contact, and providing effective measures for quality improvement of each process, avoiding complaints.

[0006] Although the staff tries to measure the invalid area to avoid scratching the effective area of the screen by the probe, since the hand-held four-probe resistance meter is currently used, the staff will still have a certain probability of accidentally pressing the probe to the effective area position of the screen glass after a long time of work, and thus causing the glass to be scratched, so the quality of the screen may cause subsequent complaints.

[0007] It should be noted that the above content belongs to the technical cognition of the inventor, and since the technical content in this field is vast and complex, the above content of the present application does not necessarily constitute the prior art. UTILITY MODEL CONTENT
