Both "lcd screen" and "oled screen" are popular labels for products such as mobile phones and computers. However, what is the difference between these two screens, it is estimated that many people cannot answer. In fact, there are many differences between these two screens. In the application scenarios, there are both overlaps and their own specializations. At this stage, no one can replace the other.
LCD and OLED have their own advantages
LCD (Liquid Crystal Display) is what we originally called a liquid crystal display. Its appearance has made the big butt (CRT picture tube) screen gradually eliminated and withdrawn from the stage of history.
OLED stands for Organic Light-Emitting Diode (Organic Light-Emitting Diode), also known as organic electric laser display. It can be inferred from the name that it can emit light by itself, unlike LCD screens that require additional light sources. This is also the main difference between OLED and LCD.
Due to different technologies, traditional LCD screens have certain deficiencies compared to emerging OLED screens in some aspects:
The lack of LCD screen
1. High power consumption
2, viewing angle limit (distortion will appear when viewing the screen at a large angle)
3, low contrast
Of course, there are also some strengths. LCD technology has been developed for a long time and is more mature. It will not be easily eliminated by OLED:
Advantages of LCD screen
1. Low price
2, not easy to damage
3, no screen flicker, more eye protection
Currently, OLED screens are mainly used in high-end mobile phones and tablets of various brands, while TVs, low-end mobile phones and tablets of various brands are still equipped with lcd screens.
Due to the high production cost and lack of stability, the OLED screen cannot fully replace the LCD screen in a short time, and this also gives the latter time and space to continue research and development and progress.
Especially in the field of super-large smart display, LCD screen is still the most cost-effective choice.
BD cell--a new breakthrough in LCD technology
It is precisely because of seeing the irreplaceability of LCD screens at this stage, after continuous research and development and innovation, BOE (BOE) launched the BD cell display technology.
BD cell can greatly improve the contrast of the display screen, which is a new breakthrough in TFT-LCD technology.
Recently, The Society for Information Display (The Society for Information Display) announced its 26th Global Display Industry Awards (Display Industry Awards, DIA) award information. 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 the LCD screen mentioned above, BD cell technology has obviously made up for it.
1. Power consumption
The screen equipped with BD cell technology has a more refined picture quality, and its power consumption is about 40% lower than that of OLED products of the same size. 2
2, the viewing angle
By being equipped with BOE’s unique ADS hard screen technology, the BD Cell display has a full viewing angle of 178°.
3, contrast aspect
BOE BD Cell adopts a black and white and color double-layer cell design, which can achieve megapixel-level partition control, and finer brightness adjustment in the sub-millimeter range, allowing visitors to experience a million-level ultra-high contrast image quality experience .
The new birth of large LCD products
Currently, BOE BD Cell technology has been applied to many high-end TV products. At this year's International Consumer Electronics Show (CES2020), well-known domestic and foreign companies such as Hisense, LG, Changhong, Konka, etc. all exhibited a series of new TV products equipped with BOE's 8K ultra-high-definition display, stunning the audience.
BOE's LCD large screen product iMAX
LCD screen technology is more mature, the price is relatively low, and it is not easy to damage. In summary, the LCD screen is still an irreplaceable solution in the display field.
Qunzhi Consulting analysts said that BD Cell is a brand-new technological breakthrough of BOE in the field of high-end LCD panels. Through the TFT-LCD technological innovation, the BD Cell display has a more delicate picture quality, and its power consumption is lower than 40% of the same size OLED products, which has both picture quality and cost advantages. The launch of BD Cell technology will help color TV manufacturers launch more competitive high-end TVs, and will also bring new vitality and market growth space for the future development of the large-size LCD industry.
