Entering the fourth quarter of this year, the prices of panels in different application categories began to diverge. According to Trendsce's latest WitsView display panel display, although China National Day sales lacked surprises, TV panel demand remained unrelenting, and the rising trend of quotes has extended the notebook panel for more than half a year, eventually losing to the slowing market demand. The uptrend formally delineated this month.
Although the fourth quarter is the peak of sales for most consumer electronic terminal markets, it is often a watershed in which the demand for related parts and components has changed from strong to weak. For the panel industry, the moderate demand adjustments in the coming months are indeed beneficial to the healthy development of the industry. However, Qiu Yubin, Senior Research Associate of WitsView, stated that the Korean TV makers may strategically maintain purchasing power and panel makers Under the influence of expected psychological factors such as the rate adjustment measures, whether the panel demand in the fourth quarter is as expected, there are indeed a large number of variables, so that the price trend that should have been gradually clear, more than a hint of the smell of flowers.
In terms of TV panels, China’s National Day television sales results showed that although National Day’s shipments in the two weeks decreased by 2% compared with the same period of last year, the lackluster results did not weaken the purchasing power of TV panels. Qiu Yubin pointed out that in addition to the fact that the sales period is decentralized, the brand still has expectations for the sales of the next Chinese Singles Festival and Christmas holidays in Europe and the United States, and the low inventory level of supplementation also adds a justifiable reason for continuation of panel purchases. Because market demand is hot and supply is limited, prices in 32W and 50W continue to rise by US$1~3 this month, while 40W and 48W continue to increase by approximately US$1 since last month, while products with 55W and above are due to supply and demand. The gap is less obvious, and the quotation is flat to within 1%.
In the monitor panel, the fourth quarter is not the traditional IT peak season, and the demand for the monitor should enter a relatively lighter period. Therefore, in addition to the price increase of US$0.2~0.3 for 19.5W this month, other items such as 18.5W or 21.5W Although some of the foundries are still waiting for food, the overall demand has cooled compared with the previous month, and the prices are mostly flat this month. According to WitsView analysis, the current level of demand for the monitor itself seems to gradually retreat to the second line and become a supporting role in affecting prices. Instead, it comes from the capacity of television panels to squeeze out, which is the maximum strength to support the price of the monitor panel.
In terms of notebook panels, North America's back-to-school surge and business machine demand will push third-quarter notebook shipments to the peak of this year, and the recent correction of global stock markets, in addition to reflecting the uncertainty of the economic situation is increasing, but also seems to indicate Why did Europe and China and other regions fail to continue the sales of laptops? WitsView expects that shipments of notebook computers in the fourth quarter of this year will decline by 8% compared to the previous quarter. Weak demand for the whole machine will impact the purchase of notebook computer panels, and 14W will bear the brunt. This month, the price of US$0.3-0.4 will decline. With the upward trend of the previous month, it has become an indisputable fact that prices have entered the correction period. Although the trend of a full-price drop in the price of the pen-and-electricity panel has not yet taken shape, the panel makers have become more frequent in negotiating project purchases with customers, and prices are likely to be the first to be sacrificed in the process of winning orders.
A Small Computer System Interface (SCSI) connector, also pounced as [scuzzy" connector, is used for physically connecting and transferring data between computers and peripheral devices.
SCSI is the small computer system interface, which is an independent processor standard used for the system level interface between computer and intelligent devices (hard disk, floppy, optical drive, printer, scanner, etc.). It is an intelligent universal interface standard, which has the function of communicating with various types of peripherals. SCSI uses the standard software interface of ASPI (SCSI programming interface) to make the driver communicate with the SCSI adapter installed inside the computer. SCSI interface is widely used in high-speed data transmission technology on minicomputers. SCSI interface has many advantages, such as wide application range, multitask, wide bandwidth, low CPU utilization, and hot plug.
SCSI connectors type and interfaces
Centronics 50-pin connector: The Centronics 50-pin connector was once the most widely used SCSI connector. An external connector only, the Centronics is a SCSI-1 connector that looks the same as the Centronics cable that attaches to a parallel port printer. The Centronics 50-pin cable comes in male and female styles, and gender changers and cable converters are commonly available. Although used on older SCSI devices and external drive enclosures, this interface is no longer heavily used, due to its slow speed and short cable lengths.
High-density 50-pin connector: The high-density 50-pin connector is used on scanners and Jaz drives. It is one of the more common SCSI connectors and is usually used to connect SCSI-2 devices. Both ends of the cable are usually 50-pin male, while the sockets on the host adapter and external devices are 50-pin female.
DB 25-pin connector: The DB 25-pin or D Sub 25 is by far the most widely used connector. This connector is used for parallel and serial printers in addition to the many other devices available. Both ends of the cable are usually 25-pin male, while the sockets on the host adapter and external devices are 25-pin female. This cable is almost always an external connector.
Note: DB-25 SCSI CABLES are not compatible with and should not be used as serial or printer cables; serial cables and printer cables should not be used or attached to DB-25 SCSI adapters. You can short out the SCSI host adapter or the motherboard by using the wrong cable. Marking cables is the best way to avoid this.
IDC50 connector: The IDC50 is the most common internal SCSI connector. It is very similar to the standard IDE internal ribbon cable. The IDC50 SCSI cable is considerably wider then an IDE ribbon cable; in fact, it is usually the widest standard internal cable in use. This is a standard SCSI-2 10MBps internal SCSI cable. Many low-end cables have only two or three connectors, allowing for one or two devices to be attached to the cable. Seven-device cables are available, though they are often expensive and require a large case, as the cables may be four or five feet long.
High-density 68-pin connector: The high-density 68-pin connector is the SCSI connector of choice for SCSI-3 host adapters and peripherals. There is an internal ribbon cable version that looks very similar to the IDC50 connector. Many low-end cables have only two or three connectors, allowing for one or two devices to be attached to the cable. Seven-device cables are available, though they are often very expensive and require a large case, as the cables may be three or more feet long. Both ends of the external cable are usually 68-pin male, while the sockets on the host adapter and external devices are 68-pin female.
SCA 80-pin Micro-Centronics connector: SCA stands for Single Connector Attachment, a type of disk drive connector that includes connection pins for the power cables as well as the data wires. A SCA connector uses an 80-pin plug and socket to connect peripherals. This connector combines power, data channel, and ID configuration for fast installation and removal. SCA connectors are typically found only on high-end SCSI hard disks. The SCA interface was designed to provide a standard connection for systems using drives that can be hot-swapped. SCA makes swapping SCSI hard drives much easier than with traditional SCSI cables, plugs, and sockets. An adapter enables SCA drives to fit into standard SCSI enclosures.
SCSI SFF 8482: Also called "4x internal" by some vendors. This is a connector with the same form factor as SATA with the addition of a "bump" to key it specifically for SAS. (SATA drives can be plugged into SAS controllers, but SAS drives will not function with a SATA controller; hence, the necessity for the key bump on the connector.) As the name says, it's meant to be used internally, i.e., inside the computer case.
SCSI SFF 8484: Also called "32-pin" or "MultiLane". This is a high density connector usually intended to plug into the motherboard, controller, or backplane itself. Cables with this connector on one end usually have four individual SFF 8482 connectors on the other.
Serial Attached SCSI SFF 8470: Also called "4x external" by some vendors. This is simply a version of the SFF 8484 that's meant to be used with external (i.e., not located within the case) drives.
