QuickTest^TM II - Small Format Display QC Test System

High speed QA and production test for small displays

The QuickTest^TM II performs rapid statistical Qualification and QC testing on cell phone displays, hand-held displays, and other small format LCD and OLED displays. QuickTest^TM II is a successor to our QuickTest I system which is installed at LCD manufacturing facilities world-wide. QuickTest^TM II provides automated testing of the following parameters:

Brightness
Contrast
Color
Color Gamut
Gamma
Cross-Talk

Uniformity
Response Time
Flicker
Voltage and current (optional)
Reflective / Transflective (optional)
user programmable test sequences allow custom tests

If you need viewing angle measurements, contact us about our QuickTest III system.

QuickTest^TM II Includes:

Control PC with QuickTest^TM II Software

LCD Monitor

Light-safe test enclosure

Semi-automated material handling system

Integrated sensor suite

Spectrometer

CCD camera

PMT flicker and response time detector

Test trays (optional)

T-Drive^TM SD-100 small format display drive system

QuickTest^TM II Benefits: In the past, Qualification and QC testing of small displays often involved a dark room laboratory with laboratory instruments mounted on home-made fixtures. The testing was labor intensive and took too long to acquire significant statistical data. This has resulted in very long test times for qualification testing and very limited QC testing.

Now, QuickTest^TM II makes rapid qualification testing and statistical QC testing possible! QuickTest^TM II provides an entire dark room laboratory in a box. QuickTest^TM II can be used on the production line or in the lab and the typical test time is less than 30 seconds per display. The QuickTest^TM II software performs Pass/Fail testing and calculates statistical process parameters, such as Cpk, while logging all test data to a database.

	Before QuickTest^TM	With QuickTest^TM
Calibration process	Disjoint calibration approach	On-site calibration service ensures QuickTest^TM II measurements meet accuracy specifications
Facilities	Dark room laboratory required	“Dark room in a box” suitable on the production line or in a laboratory
Instruments	Several laboratory instruments mounted on optical benches with manual set-up and home-made fixtures	Spectrometer, CCD camera, and PMT instruments self-contained. Semi-automated material handling
Drive electronics and Tooling	Custom drive boards are required for each display. boards are often not well documented or supported, yet are crucial to driving the display	T-Drive SD-100 drives RGB, CPU, SPI, and other small display formats. Westar offers New Display Tooling (NDT) solutions that allow a custom display to be tested on the QuickTest II platform. Click here for more information on NDT.
Test time	Manual measurements result in very long test times (often 1 hour or more)	Typical test time is less than 30 seconds.
Repeatability	Very difficult with manual measurements	Controlled instrument alignment, known display drive, accurate instruments, and light-safe environment result in highly repeatable measurements.
Statistical QA/QC	Test time too long to acquire statistically significant data	Rapid test time allows statistical sampling. Calculation of Cpk and other statistical parameters is built-in.
Qualification Testing	Labor intensive, requires a long time, manually generated reports	Short test times and automated report generation

QuickTest^TM II software provides configurable user interface and programmable test sequences
