What does this LCD TV have to do with the 8th generation panel factory?

The production line of LCD screen is divided into different generations according to the size of the substrate, which is the so-called 7th generation factory and 8th generation factory. The size of the substrate of different generations determines the optimal cutting size. Different generations of lines have their best cutting sizes, if you cut a large screen on a low generation line, it will cause a lot of useless leftovers, so the 8th generation factory is more suitable for cutting large-size LCD TVs.

Although with the improvement of LCD technology, the later production line will apply more new technologies than the old line, but the old line will generally be transformed, and the new technology is more to reduce costs and improve yields, so the performance of the 8th generation products is not necessarily higher than that of the 7th generation. At present, several major LCD production plants have built or are preparing to build 8th generation lines, which means that the cost of large-size LCD TVs will be lower than in the past.

Supplement: The performance improvement of LCD screen includes liquid crystal, black matrix, backlight, polarizer, driver circuit and other aspects. Among them, the liquid crystal can be arbitrary, and the black matrix can be re-made, all of which are replaced without being limited to the height of the generation line; The backlight, polarizer, drive circuit, etc. are all independent and outside the screen production line, and are completed in the back-end LCM fabrication.

So many of the new technologies that improve performance are not limited to the generation line.

The advantage of the high-generation line is that it is more efficient to cut large-size panels with large substrate sizes, just as a 1m*1m substrate can cut 4 panels but only 1 panel, and the substrate can cut 4 panels but only 4. Obviously, a certain substrate size corresponds to a certain display size to obtain the lowest cost.

Soft and hard screens have 8 generation lines, 8 generation lines (generation line is almost the highest generation production line that can be popularized at present, including Sharp, Samsung, LGP and Taiwan, etc., have recently begun to put into production in China, it is expected that after 2 3 years, LCD panel production capacity will be significantly overcapacity, LCD screen** will have a significant decline.

It is the production line of the eighth generation of LCD panels.

It's Sharp's, it's only Sharp's, and now it's the eighth and tenth generation production lines, and Samsung is the generation.

The cutting technology is more mature, and the technology of the LCD master is upgraded.

The 8th generation panel is good. The core of LCD TV is the LCD panel. The better the panel, the better the TV.

Well, it's a bit esoteric.

My teacher said that the current domestic brand of LCD TVs use IPS hard screen technology, which has established the 8th generation panel factory in China.

That's how it should be!

Depending on the size of the economic cut, the LCD production line is also divided into different algebras.

The liquid crystal panel is composed of two thin layers of glass substrate with a layer of liquid crystal molecules wrapped in the middle. In production, the glass substrate used has a fixed size, which is then cut to form LCD panels of various sizes. How to cut the glass substrate will make the utilization rate of raw materials higher, the economic benefits of the final product will be better, and the LCD production line will be divided into different algebras.

1. Below the fifth-generation line, most of them are used for 9-15 inch mobile products.

2. The fifth-generation line can cut up to 6 pieces of 27-inch widescreen LCD-TV substrates, and the upper limit is 27-inch widescreen TVs.

3. The most suitable size for cutting the sixth generation line is 32 inches.

4. The seventh-generation line substrate can cut eight 40-inch or 42-inch panels and six 46-inch or 47-inch panels.

5. The eighth generation panel line, the substrate can be cut into eight 46-inch and six 52-inch panels.

6. The eight-point five-generation LCD panel production line, the main economical cutting inch LCD TV panel.

7. More than ten generations of LCD panel lines can economically cut 60 70-inch LCD TV panels.

The production lines of different manufacturers, the size of the glass substrate of the same generation line is also different, how to call the algebra is mainly determined by the manufacturers themselves, and there is no unified standard in the industry. In general, the higher the panel algebra, the larger the size of the panel cut, and the greater the number of screens cut, the higher the utilization rate and efficiency, and the cheaper it can be.

The generation line can cut 6 55-inch screens, then the maximum screen size of its economic cutting is 55 inches; Cutting the same number of displays, the 10th generation line can cut up to 70 inches, while the generation line can reach 75 inches.

As the glass substrate grows, so does the optimal cutting size

The sixth generation LCD panel line.

The sixth-generation LCD panel line is currently the most popular LCD panel production line. Earlier this month, Sharp moved its sixth-generation LCD panel production line in Japan to Nanjing. In addition, China's previous Shanghai Radio and Television and Taiwan's Chimei and AUO are the main manufacturers of the sixth-generation line.

Main size: The most suitable size for cutting the sixth generation line is 32 inches, the utilization rate of the motherboard is relatively high, a motherboard can be cut into 8 pieces of 32-inch panels, and it can also be cut into 4 pieces of 65-inch panels.

The seventh generation LCD panel line.

The seventh-generation line LCD panel flourished around 2005, and there were two joint venture factories earlier, Samsung Sony and LG Philips. Samsung Sony's seventh-generation motherboard size is that it can cut 8 pieces of 40 or 42-inch panels and 6 pieces of 46-inch or 47-inch panels. Other manufacturers also have the saying of generation panels.

The 8th generation LCD panel line.

Sharp's eighth-generation line of LCD panels located in Kameyama, Japan, was put into production around 2006, and last year began to market a large number of eighth-generation LCD TVs with inch panels. The size of Sharp's eighth-generation motherboard is that it can cut 8 pieces of 46-inch and 6 pieces of 52-inch panels. LG's eighth-generation line panel is slightly larger, with a motherboard size.

The 55-inch TV, which was popular among domestic manufacturers in the second half of last year, is also largely based on the eighth-generation line.

The first generation LCD panel line.

BOE line design capacity of 90,000 pieces of glass substrate per month, substrate size 2200mm 2500mm, laid on August 31, 2009, officially started on October 19, plans to light up the first domestic large-size LCD TV LCD screen in June 2011, in September to achieve mass production. After the completion of the BOE generation line, it can produce 32-55-inch LCD screens for mainstream TVs.

The 10th generation LCD panel line.

Sharp will start production of 10th generation line LCD panels in Sakai City, near Osaka, in October, and the motherboard plans to cut 6 pieces of 65-inch panels, 8 pieces of 55-inch or 57-inch panels, and 15 pieces of 40-inch panels. It is expected that LCD TVs of the above sizes may appear as early as the end of this year or early next year.

The 11th generation LCD panel line.

The Gen 11 technology will produce eight 70-inch LCD panels using a single glass substrate with an area of 3 meters by meters.

The algebra of LCD TV panels mainly illustrates the level of the manufacturer's production line: the higher the algebra, the larger the size of the uncut substrate, so the more LCD panels are cut, and the average production cost per screen.

The lower. For example, the 7th generation substrate can cut 6 pieces of 46-inch or 8 pieces of 40-inch or 12 pieces of 32-inch LCD panels, while for the substrate produced by the 6th generation production line, if you choose the size of 32 inches for cutting, you can only get 8 panels. Although the new generation of LCD panels from the same manufacturer may indeed be better than the previous generation in terms of performance, it does not mean that the first-generation panel is necessarily better than the seventh-generation panel.

Therefore, when we buy LCD TV, we don't need to pay too much attention to the algebra of the panel. Take specific numbers as an example: Take the 7th generation line as an example:

Its glass motherboard size is 1870 2200mm, which can be cut into eight 40-inch pieces, or six pieces of 46-inch pieces, or three pieces of 52-inch LCD panels; The glass motherboard size of the 8th generation line is 2160 2460mm, which can be cut into eight 46-inch or six 52-inch LCD panels.

That refers to the problem of the size of the motherboard of the liquid crystal. For example, one LCD motherboard of his 6th generation can only cut 4 42-inch LCD screens, and the 8th generation motherboard can cut out 6-8 42-inch LCD screens.

A play on words played by producers

Should it be an 8th generation panel? What is the 10th generation panel or 8-bit panel 10-bit panel?

Several generations of panels mean the cutting process of the panel,The higher the algebra The higher the cutting process,The cost price is low,It has nothing to do with the technical quality of TV,The bit panel is to say that the smoothness of the picture The higher the bit, the higher the level of the TV picture,The color transition is relatively smooth and smooth

The wire refers to the size of the glass substrate.

The larger the generation line, the larger the area of the panel, and the more small LCD panels can be cut.

1. G5 = 1100 * 1300mm or 1000 * 1200mm, the 5th generation line roughly corresponds to the product size of 1100 * 1300 8 inches 32 inches mobile, notebook, monitor, TV.

2. G6 = 1500 * 1850, the 6th generation line roughly corresponds to the product size 1500 * 1850 18 inch 37 inch monitors and TVs.

3、g8=2200*2500

The 7th generation line roughly corresponds to the product size 1950*2250 32-inch 42-inch TV.

There is no mainstream distinction, mainly depending on the use. Look at what size of thing is used to cut. There is no difference in product technology, and the production process technology is slightly different.

Televisions have nameplates with model numbers on them. It is generally composed of letters and numbers.

The substrate size of the highest stage of the 5th generation line is 1200 1300mm, and it can cut up to 6 pieces of 27-inch widescreen LCD-TV substrates, and the upper limit of the 5th generation line is the mold rock core of the 27-inch widescreen Zaotong TV.

The size of the 6th generation line substrate is 1500 1800mm, and 8 pieces can be cut for 32-inch substrates, and 6 pieces can be cut for 37 inches, so the upper limit of economical cutting for 6th generation wire is 37 inches.

The substrate size of the 7th generation line is 1870 2200mm, and it can cut 8 pieces of 42-inch substrate and 6 pieces of 46-inch substrate. So the upper limit of the 7th generation line is 46 inches.

The substrate size of the Gen 8 cable is 2160 2460mm, and it can cut up to 8 46-inch LCD-TV substrates and 6 52-inch LCD-TV substrates. 52 inches is an economical cut size for the 8th generation line.

The substrate size of the 10th generation line is 2850 3050mm, and the number of panels that can be cut and produced is higher than that of any previous generation of production lines, and a glass motherboard of the 10th generation line can cut 15 40-inch LCD panels or 6 60-inch LCD panels or 8 50-inch LCD panels.
