Problems solved by technology

However, subject to various factors of technical strength, the current fault judgment is mostly focused on visual observation and empirical judgment, and the detection methods also stay in off-line detection methods such as multimeters and oscilloscopes. The efficiency is low, the effect is poor, the detection methods are backward, and the accuracy is not high. Low level of intelligence

Embodiment 1

[0022] Such as figure 1 As shown, this embodiment provides an LED screen display system, the LED screen display system includes an LED display screen and a detection and control device, the detection and control device is used to detect and control the LED display screen, the LED display screen The screen is used to display graphics, text, letters, animations, etc. in the video source file.

[0023] For example, the LED display screen can be a transparent LED display screen, the transparent LED display screen includes a frame and two or more PCB boards, and each PCB board is fixed on the frame, thereby forming the transparent LED display screen. Transparent LED display screen; and, one or more LED pixels are arranged on any PCB board, and each LED pixel is arranged in a dot matrix; and, the positive power line, the negative power line, and the signal line are printed on the PCB board etc., as well as other electronic components and electronic circuits, such as capacitors, res...

Embodiment 2

[0039] Such as figure 2 As shown, on the basis of the above examples, in the LED screen display system, the inspection and control device also includes the display terminal, for example, the display terminal can be a display module, and the display module and the The status feedback sub-modules are connected to each other, and display the status of the LED display screen as a man-machine display interface by receiving the detection data from the status feedback sub-modules.

[0040] For example, the display terminal can be an LED display module, an LCD display, or other display modules. Through the display terminal, the state of the LED display screen can be seen very intuitively, for example, each of the display devices can be displayed. The LED pixels and the connection lines connecting two LED pixels are in a fault state, or display a normal state.

[0041] Moreover, the display terminal is also connected to the storage sub-module, and the detection data stored in the sto...

Embodiment 3

[0043] Such as image 3 As shown, on the basis of the above examples, in the LED screen display system, the detection module is also provided with a fault warning sub-module, and the fault warning sub-module is connected to the status feedback sub-module, when the The state display data generated by the state return sub-module is expressed as, when the LED display screen fails, the fault warning sub-module generates fault warning signal data according to the state display data, and sends the fault warning signal data Send it to the display terminal, and send a warning through the display terminal. For example, after the display terminal receives the fault warning signal data, it will pop up an alarm window in real time, and intuitively indicate the fault point and fault phenomenon, so as to realize humanized operation model.

Description

technical field [0001] The invention relates to a LED lighting device display technology, in particular to an LED screen display system. Background technique [0002] With the development of LED display technology, LED display applications and LED lighting applications have become more and more widely used in various lighting applications due to their low energy consumption, strong color reproduction, long life, huge size, and unique shapes. In these applications, fault detection technology is increasingly showing its importance. Especially for LED display applications in major occasions, due to the importance of activities, the requirements for LED display fault judgment and maintenance are also higher. [0003] In the current LED display application, although the majority of users have realized the significance of LED display fault detection technology, major manufacturers at home and abroad have also carried out research and development of fault detection technology to v...
