Distributing data among test boards to determine test parameters

A system for testing a liquid crystal display (LCD) driver, the system comprising:

• multiple test boards, each of the multiple test boards comprising multiple channels, the multiple channels corresponding to data channels of the 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;
• wherein each of the multiple test boards is configured to receive partial test data from data channels of the LCD driver, and to process the partial test data to obtain a partial result;
• and
• wherein each of the multiple test boards is configured to share a partial result determined from corresponding partial test data with one or more others of the multiple test boards.

A method of testing a device, comprising:

• receiving first test data from the device, the first test data being received from a first subset of channels on the device;
• processing the first test data at a first test board to produce a first partial result;
• receiving second test data from the device, the second test data being received from a second subset of channels on the device;
• processing the second test data at a second test board to produce a second partial result;
• processing the first partial result and the second partial result at the first test board to produce a first test parameter;
• and
• processing the first partial result and the second partial result at the second test board to produce a second test parameter.

An apparatus for testing a device, the apparatus comprising:

• a first site comprising:
• first channels for receiving first test data from the device;
• and
• a first processing device configured to receive and output the first test;
• a second site comprising:
• second channels for receiving second test data from the device;
• a second processing device configured to receive and output the second test data;
• and
• an electrical connection between the first site and the second site, the electrical connection enabling communication between the first site and the second site;
• wherein the first processing device is configured to receive the second test data and to use the second test data and the first test data to determine a first test parameter;
• and
• wherein the second processing device is configured to receive the first test data and to use the first test data and the second test data to determine a second test parameter.
