"LCD screen" and "OLED screen" are popular labels for mobile phones, computers and other products. However, it is estimated that many people can't answer the difference between the two screens. In fact, there are many differences between the two screens. In the application scenarios, there are both overlap and specialization. At this stage, no one can replace the other.
LCD and OLED have their own advantages
LCD (liquid crystal display) is what we initially called the LCD, its appearance makes the big bottom (CRT) screen gradually eliminated, out of the stage of history.
OLED is called organic light-emitting diode (OLED), also known as electromechanical laser display. It can be inferred from the name that it can emit light by itself. Unlike LCD screen, it needs additional light source, which is the main difference between OLED and LCD.
Due to different technologies, the traditional LCD screen has some disadvantages compared with the new OLED screen in some aspects
The shortage of LCD screen
1. High power consumption
2. Viewing angle limit (distortion when viewing the screen at a large angle)
3. Low contrast
Of course, there are also some advantages. LCD technology has developed for a long time and is more mature. It will not be easily eliminated by OLED
Advantages of LCD screen
1. The price is low
2. Not easy to damage
3. No screen flash, more eye protection
At present, OLED screen is mainly used in high-end mobile phones and tablets of various brands, while LCD screen is still widely used in TV, medium and low-end mobile phones and tablets of various brands.
Due to the high production cost and the lack of stability, OLED screen is difficult to replace LCD screen in a short time, which also gives the latter time and space to continue research and development.
Especially in the field of super large intelligent display, LCD screen is still the most cost-effective choice.
BD cell -- a new breakthrough in LCD technology
Because of the irreplaceable LCD screen at this stage, BOE (BOE) has launched BD cell display technology through continuous research and innovation.
BD cell can greatly improve the contrast of display screen, which is a new breakthrough of TFT-LCD technology.
Recently, the society for information display announced the award-winning information of its 26th global display industry awards (DIA). BOE's 65 inch BD cell display, Apple's Pro display XDR and Samsung's folding display won the 2020 display of the year award.
For the disadvantages of LCD screen mentioned above, BD cell technology has obvious complement.
1. Power consumption
The screen equipped with BD cell technology has more delicate picture quality, and its power consumption is about 40% lower than that of OLED products of the same size. two
2. Visual angle
Equipped with BOE's unique ads hard screen technology, BD cell display can see 178 degrees in all directions °。 3. Contrast
BOE BD cell adopts black-and-white and color double-layer cell design, which can achieve multi megapixel level divisional light control, and make more fine brightness adjustment within sub millimeter level, so that visitors can experience the image quality experience of multi megapixel ultra-high contrast.
The rebirth of LCD large screen products
At present, BOE BD cell technology has been applied to many high-end TV products. At this year's International Consumer Electronics Exhibition (ces2020), Hisense, LG, Changhong, Konka and other well-known enterprises at home and abroad displayed a series of new TV products equipped with BOE's 8K ultra high definition display screen.
In addition to the LCD display equipped with BD cell, BOE also launched its own large screen products
BOE's LCD large screen product IMAX
LCD screen technology is more mature, the price is relatively low, and not easy to damage. To sum up, LCD screen is still an irreplaceable solution in the field of display.
Analysts of Qunzhi consulting said that BD cell is BOE's new technological breakthrough in the field of high-end LCD panel. Through the innovation of TFT-LCD technology, BD cell displays have more delicate image quality and lower power consumption than OLED products of the same size by 40%, which has both image quality and cost advantages. The launch of BD cell technology will help color TV manufacturers to launch more competitive high-end TVs, and also bring new vitality and market growth space for the future development of large-size LCD industry.
