To meet the high accuracy and low price requirements for LCM TV test device, Chroma 27012 that integrates the signal and power source provide a complete test solution for LCD Module. Its LVDS, TTL (Option) signal source fully complies with the digital signal standard, meanwhile with the 24V, 12V, 5V, 3.3V DC source output it is able to supply power to VDD, Backlight for LCM test without obtaining external power source. Equipped with the interface of single key to switch the Timing, Pattern and Program rapidly for test in auto or manual mode, the 27012 is able to provide a direct and convenient test environment for LCM TV by its complete hardware configuration and easy operation.
To fulfill the standard test signal requirements of various panels, this device supports LVDS signal with optional TTL signal available for use. It has 16 timings, 64 patterns, auto image rotation display system and multiple test functions settings. In addition an editor software is available for editing Timing, Pattern, Program at PC site to create a product specific test program. The design of signal and power source integration for 27012 allows it to be utilized extensively in R&D, Quality Assurance, Quality Inspection, After Sales Services, Sales fields for LCM related tests.
The Programmable Logic Device is used in 27012 as the image generator to test the LCD TV Module. It supports VGA~UXGA and 1 Link/2 Link digital signal output, also it has quartz oscillator built in to supply stable test signals as the standard signal source to the Device Under Test. This test device provides LVDS signal primarily, however, users can purchase the optional TTL signal conversion board for use to cope with the LCM TV features.
Besides the power source input of AC 100V~240V, it has the 12V, 5V, 3.3V DC power switch required by the LCM Vdd in the market and the 24V, 12V, 5V power for Backlight Inverter. Moreover, it has Signal, Vdd power on sequence to fit in the LCM TV Turn On test sequence.
As regards operation, 27012 can switch the Timing, Pattern and Program by the Mode key on the front panel directly to show the status on a 7-segament display. Users can select the required Timing and switch it to Pattern mode by pressing the Mode key, or switch it to program for test program editing; and then conduct the test automatically or manually. It can execute tests easily and quickly with the convenient operation method and multiple function keys.
