OLED, LCD screen of these things you know?

TV screen is divided into what kinds do you know? The current TV market, the frequency of updating is getting faster and faster, and a lot of new categories have been introduced. Like OLED, QLED some new picture quality technology Round LCD has also once again stimulated the desire of the majority of consumers to buy.

At present, the panel type and screen technology is too much, not to mention the ordinary consumer,UNB video wall is a professional player is also easy to confuse, today is here to do a layman's summary.

In fact, the mainstream screen material on the market is only divided into two categories: LCD (liquid crystal) and OLED (organic light-emitting diode), OLED is usually considered to be technically more advanced than the LCD,Industrial LCD but although the popularity of the OLED momentum is strong, but is limited by the price, so the LCD is still relatively more.

LCD is what we usually call LCD. it needs a backlight to display the content, and the backlight produces polarized light through the glass, color filter, optical film, substrate and alignment film, which inevitably leads to loss of color and brightness. tft is often referred to as thin film transistor. In an LCD, the TFT deposits a thin film on a glass substrate that serves as a channel region to improve image quality. The upper glass substrate is located next to the color filter, while the lower glass substrate is embedded with transistors.

A change in the electric field when current is passed through the transistors causes the liquid crystal molecules to deflect, changing the polarization state of the light, which in turn determines the brightness and darkness of the pixels using a polarizer. At the same time, the color filters affixed to the upper glass layer form the R, G, and B primary colors contained in each LCD pixel, making up the picture displayed on the screen.

OLED full name is OrganicLight-EmittingDiode (Organic Chemical Light Emitting Detection Diode), and we mentioned before the LCD is different, OLED does not need to carry out the backlighting system support. OLED is the innate surface light source information technology, light can be red, green, blue, white and other monochrome, and thus can be achieved to realize the effect of the full-color belongs to its own kind of light emitted through the A new luminous working principle. Plasma processing technology, OLED technology development and even the CRT technology in the early years of the picture quality is praised for the reason that the main problem is that the enterprise because they do not have "self-luminous" this important characteristic.

OLED technology turns off individual pixels to zero brightness. In theory, the contrast ratio of OLED technology can be infinite. As a result, OLEDs do not leak in black light fields, which improves contrast and image quality performance.

In addition, OLED technology does not require backlight support, so the liquid crystal and backlight module is eliminated, the structure is very simple, the body can naturally reach the ultimate ultra-thin, probably can be done in 1/3 the thickness of the traditional LED screen.

OLED also has the characteristics of flexible and bendable, not only can be applied to the TV, the future may be able to make smart devices full of imagination. Combined with the characteristics of OLED thin, the screen can be made into a piece of paper so thin, can be bent and folded at will, which is unthinkable in the LCD era.

Finally want to say, whether it is LCD or OLED, as long as the existence of its significance. As consumers, we do not have to get lost in a bunch of parameters, not as much as to try to go to the store to feel the real effect, so that you can choose a product suitable for their eyes.
