In recent years, TV display technology has developed faster and faster, and various new concepts have been flooded. LED , OLED, ULED, and QLED are the most troublesome examples of these various LED concepts. The description is also to make consumers feel puzzled. Today, the author takes you to identify these "X" LEDs together and makes you become a "speaking emperor."
How many "X" LEDs can you buy TV? Can you tell the difference?
"X" LED concept explanation
led
LEDs are very common in our lives. The LEDs used in the large screens of various stages are LEDs. In Chinese, LEDs are LEDs. Some friends may ask, isn't LED TVs LCD TVs? How did it become a light-emitting diode?
The LED TV uses a liquid crystal panel as a display medium and a light-emitting diode as a backlight module. When the light passes through the liquid crystal layer, the liquid crystal molecules are controlled to be deflected to different degrees, and different brightness levels can be exhibited. Then pass a layer of colored filters, let the white light color, and finally present in front of us. So in general, the LED display will be thicker.
LED backlight technology has been used for many years, it seems that it can not meet the needs of today's consumers, in order to stand out, the major manufacturers are also "eight immortals across the sea, each show magic", research and development of a variety of display technology, in front of the LED added letters to distinguish In order to put a specific label on your high-end TV. For example, Samsung's QLED, LG's OLED, and Hisense's ULED look very similar, but they are completely different technologies.
ULED
ULED is a display quality technology launched by Hisense. It adopts multi-zone independent backlight control and HiView graphics engine technology. It is stronger than LED in contrast and color gamut, and uses 2 times more backlight source than ordinary LED screen. The screen is accurately divided into 576 areas for finer image quality adjustment, but in fact ULED is also LED technology .
ULED TV can be said to be the master technology of Hisense, Hisense's ULED TV does perform very well in the picture quality, and can even compete with OLED TV, but the strength of the manufacturer layout is thin, like singing a one-man show, not conducive to technology. development of.
Antenk extended its connector product range by SD card connectors. As already mentioned there are various applications, in the past driven by the computer industry, which are using memory cards as well in their end products, single sided pressure contact connectors can be designed and manufactured according to a customer specific requirement based on customer dedicated insulator- and contact dies. Such single sided pressure contact connectors are mainly used as board to board connection on the base of direct contact to the pads on the board.
Compact Flash Card Connector Overview
Store More Memories
Compact Flash storage cards are small, removable, mass-storage devices. They electrically comply with Compact Flash Association standards, the PC Card ATA standard, and run in True IDE mode. These 50-position cards typically hold between 32 MB and 2 GB of memory and are about the size of a matchbook. Antenk`s connectors include headers that can accept Type I (3.3mm thick) or Type II (5.0mm thick) storage cards, flush and raised mounting heights, and ejectors. Antenk Compact Flash card connectors also provide electrostatic discharge protection.Adapter for Compact Flash Card type I and II
