Abstract

The invention relates to a chromatic aberration test fixture which is applicable to a color output device used for generating multiple analog signals dynamically. The chromatic aberration test fixture comprises an input unit, a switch unit, a conversion unit, a processing unit and an output unit. The input unit receives the analog signals and selectively divides the same into analog image signals and analog voltage signals. The switch unit receives and transmits the analog image signals and the analog voltage signals. The conversion unit converts the analog image signals into digital image signals. The processing unit calculates working frequency of the analog voltage signals and working voltage of the digital image signals, and compares both with default values to generate frequency test results and voltage test results. The output unit outputs the frequency test results and the voltage test results to a display screen. Through the chromatic aberration test fixture, differences of several color output devices are given consideration in a stable test environment to adjust related test conditions.

Description

【Technical field】 [0001] The invention relates to a test fixture and a test method, in particular to a color difference test fixture for testing an analog signal of a color output device, a color difference test interface device and a color difference test method. 【Background technique】 [0002] In the current test technology for color output devices, such as display chips or graphics cards, the most basic test item is the test of the analog image signal of the color output device. Stable analog image signal output means that the color output device can work normally. The premise of operation, and because in the current industrial environment, color output devices are mass-produced on a large scale, often resulting in a large number of devices to be tested, so if the traditional manual testing method is used to test one by one, it will make the test The workload of personnel has become a great burden, so how to improve the testing work of color output devices has become an i...
