Glass substrate size and product size corresponding to each generation line
Date:2025-08-06
The "several generations of LCD screens" does not refer to the level of technology, but is an industry term divided according to the size of the glass substrate used in the production line. The higher the number of generations, the larger the glass substrate, which can cut more or larger screens, thereby improving production efficiency and reducing costs.
Glass substrate size and product size corresponding to each generation line (mainstream division):
Algebra | Glass substrate size (mm) | Economic cutting size (inches) | Typical Uses |
4th generation line | 680*880 | ≤15 | Small size display, onboard screen |
5th generation line | 1100*1300 | 27 | Monitor, laptop, small-sized TV |
6th generation line | 1500*1850 | 32~37 | LCD TV, monitor |
7th generation line | 1950*2250 | 42~46 | Medium and large-sized televisions |
8th generation line | 2200×2500 | 46~55 | LCD TV |
8.5th generation line | 2200×2500 | 55~65 | Mainstream TV |
10th generation line | 2880×3130 | 60~65 | Oversized TV |
10.5/11th generation line | 3000×3320 | 70以上 | Oversized TV and commercial screen |
Matters needing attention:
-Algebraic high ≠ technological advanced: for example, a 32 inch TV produced with 6th and 8th generation lines has the same picture quality and performance.
-The main difference lies in economy and efficiency: high generation is suitable for cutting larger sizes or more quantities of screens, reducing unit costs.
-The process is slightly different: high generation lines may require vertical or inclined transportation due to the larger glass substrate, and the equipment is also more complex.
In summary:
The "several generation line" reflects the "scale" of the LCD panel production line, rather than the "technical level" or "image quality".
