Label: LCD splicing
This article refers to the address: http://
LCD splicing can be used as a display alone or as a large screen. According to different usage requirements, it can realize variable and large variable and large screen functions: single screen split display, single screen separate display, arbitrary combination display, full screen LCD splicing, double splicing LCD splicing screen, vertical screen display, image border Optional compensation or cover, support digital signal roaming, zoom stretching, multi-screen display, various display plan settings and operation, full HD signal real-time processing. LCD splicing is a complete finished product, that is, hanging and ready to use, the installation is as simple as building blocks, and the use and installation of single or multiple LCD splicing is very simple. The perimeter of the LCD splicing is only 9mm wide, and the surface is also covered with a tempered glass protective layer, built-in intelligent temperature control alarm circuit and a unique "fast dispersing" cooling system. Everything is available, not only for digital signal input, but also for analog signals. The LCD splicing series uses unique and world-leading digital processing technology to allow users to truly experience full HD large screen effects.
So, is such a perfect large-screen display system really simple? The answer is no, how to properly debug the LCD screen large screen is not as easy as people think.
Under normal circumstances, the hardware installation of the LCD splicing system will not have a lot of time and is relatively simple, and the latter is more complicated than debugging. The debugger of the video wall system has an unclear image. If the display is unsatisfactory, especially at low brightness, blurring the edges of the image, (the source resolution is too high), the interference fringe image is sampled (or dropped), and the result is that the liquid crystal of the mosaic image does not contain A clear phenomenon. Immediately determine if the product is not available. Image to control products such as systems, matrix switchers, splitters, signal transmission cables, transmission, processing and display terminals, DVDs, camcorders, computers, etc., etc. The video source shown.
Exclusions need to pay attention to two points:
First: go check the first item to bear a certain period of time, check it, it will be deleted, once the problem is solved, you can save the inspection time in other parts. First, one by one, the only way to form the resolution of a terminal display and the display resolution of the source, not only for the point, but also if the problem is not solved, it is excluded on all devices to verify the video signal, If it is dependent on the adaptation to reach the end point, or the display format, the brightness of the image can be greatly improved, or the display terminal of the replacement device can be scaled. You can increase the conversion device, such as using the nature of the signal to change the video signal. VGA video signal.
Second, please see the mechanism to make the loss to the minimum standard distance range between the image and the source impedance between the bandwidth matrix switcher. Finally, the integration of the focus and display devices is normal and the signal processing circuitry is good. The most important thing is as follows. Reliable on the high ground, good line construction, in order to make the signal ground, solid interface clean and tidy cable apart, and the strength and strictness of the total number of power supply, signal lines, such as UPS, AC power connectors at both ends, marking and managing a simple test.
Analysis: Depending on the symptoms, such as out of sync, synchronous interface cables and transmission equipment, control and display terminals focus on the frequency range of the synchronization signal source. By analyzing the test time too long, too small pictures, ghosts, transmission cables to confirm whether it is a solution to increase the signal amplifier and other equipment, or lane changes. Concentrated bad, you can adjust the display terminal.
Headphone speaker is a king of speaker unit which is used for headphone, it also called headphone driver. These speakers have high sound pressure level, fast frequency response, wide frequency response range and low distortion. Headphone Speakers are mainly used for voice headphone (e.g. customer service phone, call center headphone, military intercom headset- ) and music headphone (e.g. Bluetooth headphone, sport headphone, game headphone-).
Our main headphone speakers include:
1) From the diameter, we have speakers in 23mm ~ 57mm.
2) From the impedance, we have speakers of 32ohm/150ohm/300ohm/1000ohm.
