tft lcd display teardown manufacturer
We test the individual components for functionality and can locate defective components within very short time. We fix the component assemblies of LEDs and CCFLs, inverters, display controllers and PSUs. In many cases we also use new display controllers or inverters in order to ensure a longer life time of the monitor.
Display brightness gradually decreases or fails completely. We replace CCFL in displays from 8.4"" to 15"" within shortest time. For the future, we are also equipped for the LED backlight technology.
We stock special tubes such as W-, U- or L-shaped tubes. In this way, we are able to replace the backlight tubes for special displays such as the Sharp LQ150X1LGN2.
Polarization foils turn yellow over the years due to heat and other factors. Eventually, the displayed image becomes unclear or difficult to read. We replace polarization foils for sizes up to 15"".
I’ve always wanted to see what the latest LCD panels look like inside, and such a chance just presented itself. I got my hands on a broken 15.6″ panel, used in many laptops these days. This particuar one had DP/N number on it, so I assume it was used in a Dell. Let us see how much we can learn looking at the design with limited access to device datasheets.
The chip is labeled 8333(made by Seiko Instruments Inc) and is generating multiple voltages for the display. The three caps from L201 going to three diodes are parts of the charge pumps producing positive and negative voltages needed by the panel. (Usually +21,-9,+7 V etc). Input signals come through a 40 pin connector, with four differential pairs running LVDS.
Looks like the connector is carrying (Right to left) Power, GND, 4 diff pairs of LVDS data and what appears to be I2C data to serial EEPROM. The top of the chip has S24C on it and the let side pins are all grounded- typical pinout for an I2C eeprom, where pins 1-3 are address and 4 is GND. Only puzzling part is power pin 8 that seems to go to the connector instead of power plane, and lack any decoupling caps. The EEPROM stores the so called EDIDdata for display identification to the main system. Regular monitors do the same via signals in the VGA cable.
Update 8/5/2012: thanks to the folks at the EEVblog Forum threadfor a lot of insight on how these things work, and their help locating information on some of the parts and the display datasheet(older rev, but very close)
Over the years, LCD modules and LCD displays have grown in popularity. Companies in many different industries, including but not limited to the medical, automotive, consumer, food services, industrial, and technology sectors rely on at least one TFT LCD module or TFT LCD display on a daily basis. Although touchscreens are very durable and designed to withstand the hands of time, older modules and displays sometimes need to be repaired. When weighing the cost of having your displays repaired, you should take the time to consider your options.
After doing some research on the cost of repairs, many business owners find that it makes more sense to have their TFT LCDs replaced. Although units may cost less to repair initially, the cost of having to repair your older displays over and over again can add up. This is because older units may need to be repaired more than once. Even if multiple repairs will not cost any additional money, repairs lead to downtime and can have a tremendous impact on your business.
Older units in need of repair can have a long-term impact on a company’s bottom line. This is because outdated displays do not perform as well as new and improved displays. As many business owners have come to discover, new and improved touchscreen technology can increase efficiency, boost productivity, and improve customer satisfaction. This a top reason why so many companies decide to have a TFT LCD display or module replaced.
If you are thinking about having your older touchscreens repaired, then you should consider how having newer technology in place will help your business grow. Focusing strictly on the cost of replacing your displays can have a long-term impact on your business in more ways than one. For better results, you should consider all of the benefits of having new custom touchscreens specifically manufactured for your business. Ultimately, having new and improved displays in place for your employees and customers to use will be a business decision that pays for itself over time.

LCD panel manufacturing is divided into an Array, the Cell, such as the Module is installed in a series of technological process each process will produce some process defects, such as dim bright flash point of these defects such as broken window will cause local show bad, but we can through the laser line cut, welding, darkening method to repair or fade in the actual production in about 5% of the point defects, with a laser repair or fade out after, can promote panel product yield, and reduce the production cost of the panel companies.
Point defect is the most common problem of the LCD panel, the LCD panel manufacturing process, including dust organic metal foreign bodies will be adsorption to the LCD panel when the utensil was to close to the color filter area, corresponding to the color filter pixels emit a much brighter than the rest of the normal pixel light, which is referred to as a pixel point Semishare joint American ESI to become the industry"s first flexscan technology being developed for the pixel window, BM repair and DM repair.
