La diferencia entre la máquina de publicidad y el monitor LCD, LCD TV 2
Display area
Whether it is an LCD monitor or an LCD TV, there are industry norms for display area and display share. For example, LCD display sizes are 32 inches, 37 inches, 40 inches, 42 inches, 46 inches, etc.; and the display ratios are all controlled at 4:3, 16:9 and 16:10, and special ratios usually do not appear. In this area, the advertising machine is different. In order to meet the needs of publicity and demonstration on special occasions, advertising machines have products with non-standard display ratios, such as rectangles, squares, T-shaped, etc. Therefore, advertising machines with special needs are usually more expensive than products produced by generalized assembly lines.
Software function
The advertising machine has the function of playing audio and video, and the advertising content can be played unlimitedly, so in order to complete the display of advertisements, there will be a lot of additional hardware support, including special equipment for the advertising machine. In order to achieve large display area and higher resolution, many advertising machine manufacturers will use LCD splicing and other technologies, and there will be corresponding hardware support and software support for splicing.
Interface
In terms of civilian displays, there are usually only three interfaces, VGA, DVI and HDMI, and the DP interface is relatively rare; in the field of industrial applications, the BNC interface will be of special use. In terms of TV sets, the emphasis is on the diversity of interfaces, which can connect more audio-visual equipment, and the types and quantities of interfaces are the largest.
