Is it feasible to install a taxi on-board LED advertising display in a private car?

The color difference or brightness difference of the LED display is caused by the inadequate control of a single module in the production process, but the lack of testing in the module link or the inability to implement 100% testing will bring uncertain factors to the quality of the entire screen after assembly. This article discusses on-line automatic detection of modules, hoping to provide help for the development of the industry.

According to the inspection requirements of the display module, the original manual inspection was transformed, and the system was designed to integrate the machine vision technology into the inspection process of the LED module China. The LED module was realized without changing the hardware of the LED module. The group's online, automatic, and rapid quality testing meets the testing requirements of customers and realizes the standardization of module production. It will surely have a larger application market in the field of rapid on-site testing of LED unit boards. It is not only conducive to improving the economic efficiency of the enterprise itself, but also can promote the technological progress of the industry, promote the development of China's optoelectronic industry, improve the technical level of my country's industry, reduce and replace imports, and have significant economic benefits.

Develop a set of control system software to control the display pattern of the LED intelligent lighting solutions, use the high-precision color brightness sensor probe to detect the brightness and chromaticity of the module, and then use the self-developed data acquisition and analysis software to determine the display mode Whether the brightness and chromaticity uniformity of the group is qualified, statistics and records are carried out, so as to realize the online automatic detection and industrialization of the brightness and chromaticity consistency of a large number of LED display modules.

The principle of realizing the online detection of LED full-color screen modules is that the camera (including brightness and chromaticity probes) collects the luminous signal of the LED full-color display module on site, and the software analyzes the results in real time. The camera's brightness and chromaticity calibration is realized by standard luminance and colorimeter.

Is it feasible to install a taxi on-board LED advertising display in a private car? The first thing I want to say about this problem is that it is definitely feasible. Let’s analyze this feasible solution in the future:

First: The number of domestic private cars is growing rapidly, and the market is huge, which can meet the needs of the development of in-vehicle LED advertising and better provide such an installation platform.

Second: It can bring part of the income to private cars. Generally, advertising companies install on-board LED advertising screens on private cars, which can provide a certain amount of fuel subsidies for private cars. There is still a certain amount of money subsidies every month, why not do it.
