Appl. No.:

11/670750

Inventors:

Alexander Zellner - Ingolstadt, DE
Jeffrey S. Benagh - Melrose MA, US

International Classification:

G01R 31/02
G01R 31/00

US Classification:

702 58, 324770, 324754

Abstract:

A system for testing a liquid crystal display (LCD) driver includes multiple test boards, each which includes multiple channels that correspond to data channels of fee LCD driver, a device interface board that acts as an interface between the multiple test boards and the LCD driver, a computing device configured to communicate with the multiple test boards, and one or more communications buses over which the computing device communicates with the multiple test boards. Each of the multiple test boards receives partial test data from data channels of the LCD driver, and processes the partial test data to obtain a partial result; and each of the multiple test boards shares a partial result determined from corresponding partial test data with one or more others of the multiple test boards.

Abstract:

An example test system includes instruments for controlling testing. Each instrument may be controlled by a processing unit. Each processing unit may be configured to operate on portions of a test program relevant to an instrument that the processing unit controls. A synchronization mechanism operates with at least some processing units to produce a synchronized sequence of actions, measurements, or measurements and actions at a test instrument interface absent intervention from a centralized controller.
