Cell Phone Display Measurement System - QuickTest II+

QuickTest II+
Cell Phone Display Measurement System

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!

Display Size

Test up to 9″ displays using DUT trays for fast and repeatable display fixturing

Optical Instruments

3 instruments included: Spectrometer, CCD Camera, and Response Time detector

Fast Automated Tests

Under 30 seconds per display for most optical performance test sequences

Test Pattern Generators

Includes a Westar T-Drive SD-100 LCD Tester for automated test pattern generations and control

Designed for production line or lab

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

Full optical characterization

QuickTest II+ can be set up to run many standard test suites and other display tests as well as programmable customized tests. Contact Us to learn more.

Includes 3 optical instruments

QuickTest II+ employs three sensors, each optimized for specific measurement tasks. A high sensitivity spectrometer with a cooled back-thinned CCD provides the highest measurement accuracy throughout the color gamut for luminance, contrast and color measurements. A CCD camera provides rapid uniformity data. Westar’s proven Temporal Response Detector (TRD-100) uses a PMT to provide accurate flicker and response time measurement. All systems come factory calibrated to specification with available optional annual on-site calibration service to ensure accuracy specifications are maintained over time.

Test Pattern

Automated test pattern generation

QuickTest II+ comes standard with our T-Drive SD100 LCD Tester. 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 platform.

Fast and easy to operate

QuickTest II+ verifies critical optical performance parameters of cell phone display modules in an easy to use automated fashion. The graphical user interface allows the operator to select a pre-defined test configuration, start, and stop the test. The operator places a pre-loaded tray, containing the display, on QuickTest’s sliding drawer. The drawer closes and places the display in a controlled lighting environment. The system energizes the display and performs the selected series of tests. The results are compared to stored test limits and the system indicates pass/fail status of the display. The measurement results are then logged to a database. The drawer opens and the test is complete.
