Embodiment Construction

[0010] see figure 1 , the graphics card testing system of the present invention includes a computer 10 and an adapter board 30 . This computer 10 comprises a test data generating device 19 and a system I / O (input / output) 17 for data input and output and a data processing control device connected with the test data generating device 19 and the system I / O 17 respectively 15. A graphics card 11 to be tested can be integrally installed in the computer 10 or plugged in the computer 10 through a PCI (periphery component interconnect) or AGP (accelerated graphics port) interface and connected with the data processing control device 15, the graphics card 11 It has a VGA (video graphics array) output interface that can be connected to a monitor. The VGA output interface of the graphics card 11 is an analog signal output interface. The VGA output interface of the graphics card 11 outputs three primary colors (RGB) of pixels, and the three primary colors include red (represented by R)...

Abstract

A display card test system is used for testing a display card with an analog signal output interface, comprising a computer provided with the display card and an adapter panel connected with the computer; wherein, the computer comprises a test data generating device which generates original test data and a data processing control device which receives the original test data and outputs the data to the display card; the adapter panel comprises an analog-to-digital converter (ADC) which receives the analog signals output by the display card and converts the analog signals to the digital signals to be output and a data output controller which receives the digital signals output by the ADC and converts the digital signals to the digital signals that can be identified by the computer as well as passes the identifiable digital signals back to the data processing control device of the computer; the data processing control device compares the received digital signals with the original test data. The display card test system can test the display card automatically based on the computer, thus improving the working efficiency. Besides, the invention also provides a corresponding test method.

Description

technical field [0001] The invention relates to a graphics display card (hereinafter referred to as "graphics card") testing system and method, in particular to a graphics card testing system and method for testing a graphics card with an analog signal output interface. Background technique [0002] Graphics card is an important component of a computer, and its function directly determines the display effect of the computer and even affects the performance of the entire computer, so it is very important to test the performance of the graphics card. [0003] The traditional test method is to directly connect the output interface of the graphics card to a monitor, output the test image by running the test program, and directly judge the display result by human eyes. This requires more manpower when mass testing is performed on the production line, which increases testing costs. In addition, the display itself has a certain display effect, so the judgment result will be limite...
