LED display screens can use dedicated large screen signal processing machines to convert interlaced TV signals into progressive scanning signals, which are then played on the large screen. The high-performance processing function can handle up to 10 or more bits, and interpolation, motion prediction and compensation, and scanning transformation are required when performing scanning transformation. Nowadays, advanced large LED screens also adopt this method and perform more image signal processing, striving to elevate the signal to the broadcasting level, and of course, the effect is also better.
Computer images also need to be processed by this processor and then sent to the large screen for display. Processing technology is still constantly evolving, and many new algorithms have been proposed. This method is widely used in large-sized back projection televisions and plasma large screen televisions that we are familiar with, and the results are much better than ordinary televisions. In this case, the output signal is usually described in the transformed signal format, which appears more accurate.
Another type of screen signal processing for LED displays is the multimedia method, commonly known as the synchronous screen method. This method uses a regular multimedia card to capture TV signals, and performs demodulation, filtering, and timbre separation. After undergoing A/D transformation, the image signal is compressed using MPEG encoding for storage. During playback, decompress and watch directly on the computer monitor.
