Embodiment 1

[0030] Such as figure 1 As shown, this embodiment provides an automatic test system for non-standard display equipment, including a host 1, a power supply module 2, a video signal source module 3, and a color analyzer 4;

[0031] The power supply module 2, the video signal source module 3, and the color analyzer 4 are all electrically connected to the host 1;

[0032] The power supply module 2 is used to supply power to the display device under test according to the power supply instruction sent by the host 1;

[0033] The video signal source module 2 is constructed based on FPGA technology, and is used to provide a non-standard video signal in TTL format for the display device under test according to the image output command sent by the host computer 1;

[0034] The color analyzer 3 is used to analyze the color information of the display device under test according to the color analysis instruction sent by the host computer 1;

[0035] The host 1 is used to send power suppl...

Embodiment 2

[0042] This embodiment provides an automatic test method for non-standard display equipment, which is tested by using the above-mentioned automatic test system for non-standard display equipment, including the following steps:

[0043] Access to the display device under test;

[0044] The host controls the power supply module to supply power to the display device under test; for example, it provides 28V DC power supply for the display device under test and provides overload protection;

[0045] The host computer controls the video signal source module to send non-standard video signals to the display device under test; the color analyzer collects the color information of the display device under test, and judges whether the display parameters of the display device under test conform to the design indicators according to the collected color information;

[0046] The host automatically obtains the output of the display device under test and judges whether it meets the requiremen...

Abstract

The invention discloses an automatic testing system and method for non-standard display equipment. The system comprises a host, a power supply module, a video signal source module and a color analyzer, the power supply module is used for supplying power to the tested display equipment; the video signal source module is constructed on the basis of FPGA technology and used for providing non-standard video signals in a TTL format for a tested display device. The color analyzer is used for carrying out color information analysis on the tested display equipment; the host is used for sending a power supply instruction, an image output instruction and a color analysis instruction; and the host is also used for carrying out communication protocol verification according to the communication information of the communication interface and the tested display equipment. A video signal source module constructed based on the FPGA technology is adopted, non-standard video signals can be output, a color analyzer automatically analyzes color information, and color analysis and measurement efficiency is effectively improved. According to the scheme, testing of display parameters, video signal integrity and a communication protocol can be automatically completed, manual participation is reduced, the testing efficiency is improved, and the consistency of products is guaranteed.

Description

technical field [0001] The invention relates to the field of display device testing, in particular to an automatic testing system and method for non-standard display devices. Background technique [0002] With the development of display technology and the upgrade of various video communication buses, the degree of automation and integration of non-standard displays in special environments is getting higher and higher, and the technical complexity is also increasing. In order to ensure its reliability, it needs to be strictly tested in the life cycle of production use and maintenance to ensure its normal function. [0003] Existing airborne displays are usually integrated display and control devices. When testing, it is necessary to conduct a comprehensive test on display parameters, video signal integrity, bus communication protocol, etc. Especially when the image display signal is a non-standard signal, a dedicated video signal generator is required for measurement, and c...
