OLED (Organic Light-EmitTIng Diode), the full name of "organic light-emitting diode", is a display screen technology. The OLED TV manufactured by OLED technology no longer needs an LCD liquid crystal panel, and the RGB color signal is directly displayed by the OLED diode, and there is almost no problem of viewing angle of the liquid crystal. The blue light band produced by it mainly concentrates at 460 nm, which is not harmful blue light, and the energy is small, and the harm to the human eye is minimal. LED TV, in fact, is still an LCD screen, but the backlight is changed from the original CCFL fluorescent lamp to white LED illumination, so it is also called WLED (white light diode). OLED TV, LCD LCD panel is no longer needed, RGB color signal is directly displayed by OLED diode, almost no viewing angle problem of liquid crystal Today's LCD screens use LED backlights. Since backlights require the effect of white light, the industry uses blue LEDs to mix yellow phosphors to form white light. Since the blue LED is a main hardware, the blue spectrum in this white light has a peak, which forms what we call the harmful blue light. [2] LED LCD TV is the main carrier of living room entertainment. Most families choose to watch TV at night before going to bed. Even many people will turn off the lights when watching TV, plus the splash screen and other factors, causing harmful blue light to cause damage to the eyes. [2] The screen panel of the OLED TV can independently emit light from each pixel, and no backlight is needed. The OLED organic light-emitting body has 33.17 million solid particles, [2] can automatically emit light. As long as the voltage is input into the electrode, the excitation layer can generate the required colored light, and the generated blue light band is mainly concentrated at 460 nm, which is not harmful. Blue light, with less energy, is of little harm to the human eye. [2] The gap between PDP plasma TV and OLED TV is huge, and plasma technology can't escape the fate of “not yet popularized and eliminated firstâ€. PDP (Plasma Display Panel) plasma technology originated in the 1990s. Since the advent of the TV industry, it has been in advanced technology in the field of television. It is used in the high-end products of various brands. However, due to the high price, there are very few plasma TV products on the market. Failed to gain popularity. Coupled with the rapid development and market popularity of LCD LCD screens, plasma TVs are considered to be superior to LCDs, but their clumsy product size, several times higher than LCD prices, is actually like the Japanese royal family. There is a beautiful name, and the name is dead. Although PDP has higher contrast, color and response time than LCD products, its picture can be compared with OLED. However, OLED display products still significantly lead PDP technology in terms of display density, viewing angle and unit energy consumption brightness. The products, especially in the ideal thickness of the product, are less than one-tenth of the PDP and appear to be lighter and thinner. From the point of view of manufacturing cost, OLED and PDP are almost equal in terms of large-size display. However, in the construction of the production line, the cost of OLED is significantly higher than that of the PDP, which may reach several times or even 10 times the investment in the construction of the PDP product line. This is a major bottleneck in the mass production of OLED products. Although the investment in the preparation of OLED products is even greater, PDP products still have no advantage in the market. Because LCD products, which are also more expensive than PDPs, have gained market advantages for PDP's main large-size display devices. This advantage will be fully inherited by the OLED technology that can inherit the LCD production line. Or, it can be said that the success of LCD today has helped OLED to complete the first step of investment. The conversion and upgrade of LCD to OLED is inevitable, and the scene of LCD victory over PDP will be inherited by OLED in the near future. On March 27, 2017, Sony's annual charm "Sony Expo 2017" was officially held in Guangzhou. This event can see Sony's many black technology products, the most anticipated of which is that Sony will officially announce OLED. The official price of the A1 TV. All along, the predicted price of Sony OLED A1 is between 50,000 and 70,000 yuan. After all, the design is so outstanding and the performance is so excellent. The price of LG OLED G6 is 60,000 yuan. Sony OLED A1 is not reasonable. This year, the OLED market has attracted a lot of attention from high-end OLED TVs due to the entry of international companies such as SONY, and the products have won many praises in this year's market. The most representative product is Sony's latest OLED A1 series this year. Due to its excellent performance and numerous black technology blessings, shipments exceeded expectations, accounting for almost 30% of OLED TV's market share. However, Sony does not seem to be satisfied. Recently, the author found in Sony's official mall that Sony OLED A1 began a new round of price cuts. Among them, 55 inches straight down 3,000 yuan, the best-selling 65-inch product went straight down 4,000 yuan, while the 77-inch A1 TV dropped a lot, straight down 30,000 yuan, the price is only 119,999 yuan, local friends do not hesitate, can directly Get started! The A1 series is a great work for Sony to return to the OLED TV market after many years. It is equipped with Sony's original screen sound field technology and 4K HDR image processing chip X1 advanced version, which continues the brand's minimalist Japanese aesthetics and achieves more immersion. The sense of sound and picture performance further stabilized Sony's competitive advantage in the high-end large-screen market, and with many black technologies once again led the transformation and upgrading of the OLED TV field, which can be said to be a phenomenal product in the TV market this year. It is understood that Sony OLED TV A1 is equipped with 4K HDR image processing chip X1 advanced version, which can bring out the advantages of OLED "self-illumination, wide viewing angle, high contrast", bringing deeper and purer black, more realistic and delicate light and shadow performance. And more precise color management. At the same time, by integrating object-based HDR dynamic item-by-item reshaping technology, 4K HDR 14Bit smoothing gradient and dual image database, A1 series TV can analyze and optimize the picture object frame by frame to further enrich visual expression. The user's visual experience is pushed to new heights.
