The QuickTest™ II+ performs rapid statistical Qualification and QC testing on cell phone displays, hand-held displays, and other small format LCD and OLED displays. QuickTest™ II+ is a successor to our QuickTest™ system which is installed at LCD manufacturing facilities world-wide.

In the past, Qualification and QC testing of cell phone displays often involved a dark room laboratory with optical instruments mounted on home-made fixtures. The testing was labor intensive and took too long to acquire significant statistical data. This resulted in very long test times for qualification testing and limited QC verification. With its  integrated instruments, display drive, and powerful software, QuickTest II+ makes rapid qualification testing and QC testing possible!

charroo you really just need a few additional tools. You still need an oscilloscope just like in the "olden" days. LED/CCFL tester is always good to have. This will allow you to test the panels backlight. Than you need a good multimeter, a capacitance meter still comes in handy. After that, get a couple of good hand tools like a set of Philips screwdrivers. What you definitely will have to have is a good set of schematics. Since most of the boards are meant to be replaced there is not a lot of component information out there. So I"d focus on that. Always keep a good supply of common replacement boards. I prefer to repair Samsung, Sony and Panasonic over Vizio :-)but then I am just a tinkerer. There really are no LED TV"s (just ask Samsung). You"d be dealing with LCD/DLP and Plasma TV"s out there

Advanced LED technology has enabled big breakthroughs in the colour, resolution and  appearance of the display. Quality, accuracy and the standard display production operations have also been enhanced. Displays, single components and panels must be objectively tested at all stages of the manufacturing process. The measuring instrument employed simulates the human eye or visual system. It ensures that the displays meet several standards through the objective evaluation of display characteristics like:

Display measurement systems must be configured to perform different types of display tests in such a way that they do not introduce error into the measurement process. Parameters such as chromaticity, gamma, white balance, contrast, flicker and uniformity are important when characterising LED displays. A few LED display testing equipment available in the market today are described briefly below.

The Gamma Scientific-1290 NED system  provides test capabilities for a wide variety of parameters including luminance and colour uniformity, pixel/line defects, contrast, image virtual distance, image distortion, the field of view (FOV), resolution and response time. It can cover over 160-degree FOV with high- resolution measurements in the virtual image space. It provides precision angular alignment to the device under test.

Instrument Systems has been providing all-in-one systems for display measurement since many years. The DTS 140D display test system is an all-in-one system optimised for high measurement accuracy, maximum stability and high variability. It includes the following components:

The ProMetric I is a high-resolution imaging colorimeter designed to address the demands of high-volume display manufacturing. Whether you need to expand test coverage or increase

The advancement of AR/VR technology continues to find its way into a variety of markets and applications. Innovative design for manufacturability as well as automated optical testing will be essential in such volume-manufacturing environment.

The 7661A is designed with embedded darkroom environment that enables common area manufacturing operation. User-friendly software provides flexible setting of test parameters such as the pass/fail criteria and many others. This system can save test data in a local server or optionally be equipped to upload test data to SPC, MES or Shop Floor Management Systems.

The 7661A automated optical micro display test system is engineered to solve your next optical test challenge and ensure a seamless transition from the laboratory performance to the production floor.

Today, semiconductor and LCD panel manufacturing equipment is essential for the production of all kinds of electric and electronic appliances, including PCs, cell phones and flat-panel televisions. Advances in this equipment promote enhancements to PC performance and cell phone functions, and enrich people"s lives by reducing the cost of flat panel TV sets. THK"s products can meet this kind of high-technology need for fine movement control.

Compact ball screws and Caged Ball LM Guides exhibiting very smooth movement are used in highly efficient production systems used for LCD panels for car navigation systems and mobile tools.

In order to test the electrical characteristics of LCD panel substrates, the measuring instrument must be capable of positioning the substrates accurately over a wide area. LM Guides and ball screws, machined to a high level of accuracy, can provide this tracking control and contribute to efficient manufacturing even as the size of the substrates increases.

LCD manufacturers inspect display substrates at many stages of production to maximize yield, minimize scrap, optimize equipment utilization, and monitor manufacturing processes. At the completion of the array stage of manufacturing, the performance of each of the millions of individual transistors on each display are tested. This electrical test is referred to as "array test."

In addition to the robotic touch testing, the test system is also able to carry out a variety of different tests, so to verify all the product characteristics within a single test stage:

Optical inspection. Pattern matching test, dead pixel recognition, backlight brightness and color test can be performed to ensure the display is defect-free, with an accuracy able to verify the goodness of every pixel also on the newest microLED technologies.

Electrical test. The test system can house all the resources to contact and test electrical and electronic parts of the device, recognizing defective parts and detecting process defects (such as open pins and short circuits)

Acoustic test. Correct sound emission from the device (e.g. when a buzzer is present) can be verified via dedicated, robotic units. Extreme accuracy can be guaranteed by anechoic chambers.
