Abstract

The invention discloses a testing fixture and testing method of display signals. The testing fixture is suitable for being connected with a display signal generating device with a plurality of display ports and an analysis host, and the display ports are used for outputting the display signals respectively. The testing fixture of the display signals comprises a master control circuit board, a switcher and an image acquisition unit. The master control circuit board is electrically connected with the analysis host and the display signal generating device. The switcher is electrically connected with the display ports of the display signal generating device and the master control circuit board, and provided with a plurality of switching lines for transmitting the display signals. The image acquisition unit is electrically connected with the switcher and the master control circuit board, and the image acquisition unit receives the display signals transmitted by the switching lines and transmits the display signals to the analysis host. Whether the output of the display ports is normal or not can be automatically detected through the testing fixture of the display signals, and human eyes do not need to view the display states of display equipment one by one.

Description

technical field [0001] The present invention relates to a display signal test fixture and test method, which are suitable for a display signal generating device and an analysis host, and particularly relate to an analysis host to perform tests for switching multiple switches to transmit display signals, for use in To analyze whether the electrical properties of the display signal generating device and the display interface are normal, and to improve the test coverage. Background technique [0002] Nowadays, with the introduction of diversified image output products, such as the digitalization of TV, the advent of high-definition images of Blu-ray players and 4K TV sets, and the popularization of personal mobile devices such as mobile phones and tablet computers, consumers are pursuing convenience and high-quality images. In the context of audio-visual entertainment, traditionally there is no clear boundary between consumer usage scenarios and habits, resulting in a sharp in...
