Problems solved by technology

[0003] However, the current mobile phone display operating system has many deficiencies, such as different mobile phone platforms, and the display screen interfaces used are also different. Now there are three mainstream interfaces, MCU, RGB, and MIPI. The protocols for different interfaces are different, and the testing methods and The hardware is also different
It is very troublesome to manage the software and hardware of the factory
The traditional operation needs to add a lot of peripherals, the operation is cumbersome, and all the information needs to be sorted out to complete the understanding of product performance; the cycle is long, so a visual liquid crystal display operating system is proposed to solve the above problems

Abstract

The invention discloses a visual liquid crystal display operation system. The system comprises the steps that 1, a test fixture is provided; 2, a model to be tested is input through a human-machine exchange module; 3, configuration parameters are imported; 4, a display screen is connected with the fixture through an LCD interface; 5, a CPU conducts electrification detection on a display module, reads the ID of the display module and whether current conforms to a configuration file, initializes the display screen if yes, and conducts electricity supply interruption and gives an alarm if not; 6, whether an image is abnormal is judged, it is concluded that the tested display screen is qualified if not, and it is concluded that the tested display screen is unqualified if yes. The system has the advantages that different interfaces are configured through software on the premise that hardware is unchanged, and operation on different interfaces and different types of hardware is simplified; information of tested products can be saved and loaded directly next time, repetitive work of engineers is greatly simplified, and working efficiency is improved.

Description

technical field [0001] The invention relates to a display operating system, in particular to a visual liquid crystal display operating system, and belongs to the technical field of application of mobile phone display screen interface testing methods. Background technique [0002] Along with the development of science and technology, mobile phone is widely used as a kind of tool of people's communication, and the main man-machine interface of mobile phone is exactly liquid crystal display, a kind of display type that liquid crystal display is used for digital clock and many portable computers. LCD displays use two sheets of polarized material with a liquid crystal solution between them. Passing an electric current through the liquid rearranges the crystals so that light cannot pass through them. Thus, each crystal acts like a shutter, allowing light to pass through and blocking it. The development of liquid crystal display technology is just in line with the current trend o...
