Auto (ratio) adjustment type 1, a mechanical booster type, Shandong full color that is driven by a servo motor carbon brush in the sliding surface of the autotransformer winding movement, full color display manufacturers to change the ratio of Vi Vo, and full color to adjust and achieve a stable output voltage. Shandong full color display manufacturers this kind of regulator can be from a few hundred watts to several kilowatts. It is characterized by simple structure in Shandong full color manufacturer color screen, low cost, output waveform distortion; Shandong full color Which is good but due to carbon brush sliding contacts outdoor color screen is easy to produce a spark, causing damage and even burn brush and failure ; and the voltage adjustment is slow. 2, change the tap type, the autotransformer made Shandong full color multiple fixed taps through a relay or triac (solid state relay) full color manufacturers offer as switching device 10 Shandong color screen, automatically change the wiper position, thereby achieve a stable output voltage. Standard video input (RCA) interface is also known as AV interface, usually in pairs, white and yellow audio interface video interface, it usually RCA (commonly known as RCA) to connect, simply with the use of standard RCA AV cable to connect to the corresponding interfaces. AV interface separation of audio and video transmission, which avoided because the audio / video mixing interference caused decline in image quality, but the AV interface transfer is still a luminance / chrominance (Y / C) video mix Linyi signal color screen, still need to display its bright / color separation and chroma decoding can imaging, this mixing process was first isolated signal will inevitably result in the loss of color, color signal and luminance signal will be a great chance of mutual interference and thus affect the final output image quality. AV also has a certain vitality, but because of its own Y / C mix this insurmountable disadvantage can not be used in pursuit of visual limits of occasions. p10-color screen, Yasuhiro photovoltaic (certified), Heze, Linyi color screen provided by the Thai-Hong Electronics Co., Linyi Wang Tai Electronics Co., Ltd. (www.ledzkd.com) (www.ledzkd.com) is a leader in Linyi, a display device, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. In Hong Thai Optical leadership with the staff warmly welcome all inquiries negotiations to create the Thai macro photoelectric a better future.
