At present, only Samsung and LG's splicing screens of international brands on the market are originally produced by itself (BOE original splicing screens will come out this year), and other so-called large-screen display manufacturers known as "Samsung DID splicing screens" are all outsourced by Samsung. , LG's panel assembly. The fundamental reasons for the difference are: 1. The original product has the matching and compatibility of products, performance, and design; 2. The manufacturers have different levels of technology research and development, production technology, and market concepts. Below we will discuss in detail the source of the market price difference of splicing screens (original and non-original, and between non-original manufacturers) on these two points. The composition of a single splicing unit is as follows: panel, signal input processing chip (there are many types of chips, here is one), power supply board, display board, driving motherboard, etc. The difference between original and "cottage", brand manufacturers and non-brand manufacturers, companies with core display technology and some small companies lies in these subtleties, ranging from electronic components (IC, capacitors, inductors, coils) to structure Design and system management are quite different. 1) For large screens, the panel is very important, accounting for more than 70 percent of the cost. Industrial-grade DID panels are also divided into A-grade, B-grade, C-grade, and A plus and A plus plus grades. The original splicing units of Samsung and LG use first-line A plus high-quality panels. Reduce costs without hesitating to use inferior panels.
