lcd panel cof data price

Bonding machine has graducally replaced the traditional manual cof bonding process and now is widely used by repairer in their repairing shops for TV laptop screen repairing and refurbishment.

Our bonding machine can repair all display problems due to COF damage. It adopts pulse heating method to make the bonding process more efficient and save your time. You can repair more TV screen panels per day and expand your repairing business. It is also equipped with 2 CCD high definition cameras with one front PCB camera which make the bonding process more accurate.

Compared with other bonding machine, our bonding machines are made of famouse brands parts. We use our special U trail design to make sure the bonding head will not lower down rapid and easily controlled. It can well aviod breaking the glass panel due to rapid lowering down speed.

Our machine also has vacuum absorption function to make the panel is steady while bonding cof/tab. Our bonding machine can be used to repair and bond FPC,COF,TAB, COG and FOG of all screens up to 100 inches.

TAB COF IC supplier in India. Panel Repair Factory is the biggest COF IC Dealer worldwide. We have the largest COF IC stock in the world with around 1500 different COF IC, COF IC supplier in Delhi, COF IC Dealer in India

Panel repair factory is one of the top COF IC suppliers. COF stands for Chip on film. Each of them comes with a wide range of features and specifications. The COF IC supplied by panel repair factory is capable of receiving Signals and digital data and in turn, reversing it into analogue signals which are then sent to the receiver device. The COF IC is commonly used in LCD TVs and O LED devices. It is capable of high accuracy and ensures panel pixel uniformity. It is highly useful in the interconnection of the LCD driver ICs. It comes with sufficient film thickness that is not only flexible but can be easily used for any purpose. In addition to this, the panel repair factory COF IC possesses pretest capability which makes it in high demand for product fabrication applications. It combines the power of interconnection Technology that covers all the needs of LCD panel applications that feature high resolution. It is suitable for use with all electronic products whether they are lightweight or heavyweight.With it, you can easily package IC chips of any dimension. It is also capable of packing multiple chips and passive components within its circuit films.

I have two LCD one of Panasonic 32 inches its panel was damaged last 5 days and 2nd one 32 inches Samsung LCD in this problem is from the 2-3 inches upper side shows black n white with one horizontal line in the panel.this is repairable or not. My no-9899702493,9999000471

i have a cracked LCD panel from a LG 43LF510V . Screen model is HC430DUN-SLNX1 How much would it kost to ship in Italy ? In euro please. Thank you very much.

1. #Confirm whether the COF on side X is hot compared with the normal temperature, whether there is fracture or wear crack, and whether the COF is burnt.

2. #Confirm whether the VAA is normal (normally about 17V). If abnormal, disconnect the RP32 to confirm whether it is caused by DC/DC loop or X-side COF: disconnect RP32, if the VAA is normal, the COF is bad, CO must be changed; COF can be Disconnect one by one to determine which NG disconnects RP32, VAA NG, try to change UP1; at the same time, confirm whether the continuity of the surrounding triode is OK.

3. #Confirm whether the RSDS value is correct, normal RSDS is about 1.2v, and the signal difference is about 200mV; At the same time, we can confirm the resistance between RSDS signal (normal 100 or 50 ohms) and RSDS resistance to ground. If the voltage is NG, check if the ASIC and X-COF are hot.

2. #Confirm VGH/VGL voltage (about 30V VGH and -6v VGL), and confirm whether it is DC/DC loop NG or COF IC NG; The corresponding resistance of disconnected VGH and VGL can determine whether it is a DC/DC problem or a COF-IC problem. If it is DC/DC NG, try to replace UP1 or confirm whether the corresponding transistor is OK.

3. #Confirm whether the gate IC is OK. There is a signal test point on the back of COG IC, which can scrape the green paint for measurement confirmation; Or cut COF halfway from G3. If there is a gate-ic problem, which IC fault can be confirmed.

B. Confirm VAA resistance to ground at VAA test point of R plate (A short circuit usually occurs), disconnect the corresponding capacitance of the following 3 COF, and confirm VAA resistance to the ground again. If OK, replace the capacitor, if NG, replace COF. If VAA is still NG, confirm DC/DC loop as all models.

3. #Shaking module, if vertical lines disappear or reappear, then it can be judged that the possible cause is COF pin broken, and the crease should be found under the OM microscope.

4. #Press the LCD glass side of the panel, if the vertical lines disappear or reappear, it can be judged that the cause of poor contact, OM checking should be able to find the poor contact.

5. #If there is no display change in pressing, confirm whether ITO is damaged under the OM microscope, or pin signal waveform corresponding to needle COF.
