OLED (Electro Luminescence) is highly anticipated as a light source that, like LED, contributes to energy conservation and can achieve higher degrees of lighting freedom than LED. OLED has not yet been fully put into practical use, and there are also quite a few topics. However, on OLED displays, there is a revolutionary aspect that can overturn traditional lighting concepts. Its unprecedented biggest feature is that the light source itself emits surface light. Existing lighting, including LED lighting, utilizes point and line light sources to illuminate space. When surface lighting is needed, multiple point and line light sources are always arranged together and covered externally

OLED manufacturers take you to understand the luminescence principle of organic EL
OLED manufacturers take you to understand the luminescence principle of organic EL. Organic EL, also known as Organic Electro Luminescence (OEL), means the electronic version of organic luminescence. Although the definition is very general, it covers a wide range, such as organic light-emitting diodes, luminescent polymers, and other organic substances that utilize physical luminescence phenomena. The principle is roughly the same as LED, except that it uses organic compounds with diode function. So, to put it simply, the difference between the two is that the mainstream organic EL technology is now developed by the American giant film company Ke

OLED TVs are getting cheaper, is LCD TVs still worth buying?
How to choose OLED and LCD TV? The development of technology has made people's lives simple and rich, and there are various ways to access video entertainment information. Apart from the generation of grandparents who still watch TV programs, the younger generation may be more inclined to browse their favorite programs on tablets or phones. This change came so suddenly that it almost caused television to withdraw from the historical stage and become the "background wall" of the living room. But this kind of stimulation is not necessarily a bad thing. It has accelerated the iteration of television display technology, and major manufacturers are also vigorously promoting the birth of new technologies, trying to show consumers that televisions are in demand

Nowadays, many Western countries have taken the lead in using OLED lighting fixtures. The emergence of this type of lighting fixture has brought the development of the lighting industry to a new stage of development, and has begun to spread worldwide. Although this technology started very late in China, there is also a rapid development trend. So what are the characteristics of OLED lighting fixtures? Let's listen to the analysis by the technical personnel of Tuo Wei. 1. Oled lamps, as a new type of lighting fixture, have the characteristics of a true flat light source, achieving the natural advantage of uniform and soft light distribution. 2. The LED lamp achieves low-voltage direct current drive and does not contain toxic substances such as mercury, which radiates from external sources

Is the widespread use of LED lights due to their advantages?
When it comes to OLED lights, many consumers may not be very familiar with them, because this type of lighting is a new technology that has not yet been widely adopted. However, the magical effects of OLED lights will inevitably lead the future development of the lighting industry. Why is this? Tuo Xiaobian, let me talk to you about OLED's current competitive advantages. Nowadays, the majority of our current applications are LED lighting fixtures, which are more energy-efficient and environmentally friendly, so they are highly favored by the market. However, this type of lighting fixture also has its own shortcomings. For example, LED lighting fixtures produce a large amount of blue light, which is very detrimental to our health

The Manufacturing Principle and Component Manufacturing of OLED
OLED display screen components are composed of n-type organic materials, p-type organic materials, cathode metals, and anode metals. Electrons (holes) are injected from the cathode (anode), transmitted through n-type (p-type) organic materials to the luminescent layer (usually n-type materials), and then recombined to emit light. Generally speaking, the glass substrate made of OLED components is first sputtered with ITO as the anode, and then sequentially coated with p-type and n-type organic materials, as well as low work function metal cathodes, through vacuum thermal evaporation. Due to the easy interaction between organic materials and water vapor or oxygen, dark spots (Darkspots) are generated, causing the components to not shine. Therefore, this component

What is the preparation process for OLED?
Due to its simple structure, the production process of OLED displays is not as complicated as the LCD manufacturing program. However, due to the continuous improvement of OLED process equipment and the lack of standardized mass production technology, the differences in active and passive driving as well as full color methods will affect the OLED process and unit design. However, the entire production process requires a clean environment and supporting processes and equipment. Improving the performance of devices not only requires starting from the chemical structure of the material, which forms the foundation of the device, but also improving the material performance and enriching the variety of materials; It is also necessary to have a deep understanding of the physical processes and internal physical mechanisms of the device, with a focus on

Nowadays, people's work and life are increasingly dependent on electronic devices. The typical life of urban white-collar workers is to watch their computers at work and their phones at leisure after work. It is normal to spend 8 to 10 hours a day watching the screen. So, is using a phone, LCD, or OLED screen every day more eye-catching? We can talk about the harm these two types of screens cause to the eyes. LCD screen - Shortwave blue light damage. Nowadays, LCD screens are displayed with LED backlight. Due to the need for white light in backlighting, the industry typically uses blue LEDs mixed with yellow fluorescent powder to form white light. Therefore, this type of screen sends

Why can OLED displays be bent, but LCDs cannot?
In terms of physical properties, LCDs are not suitable for curved surfaces. OLED displays can be bent or even folded to any extent. Currently, curved displays sold on the market are mostly fixed curvature, which may cause distortion and discoloration of the image. Their prices are also relatively high. Overall, curved LCD displays may be a transitional product for consumers to pay a high price, This is also a compromise in the current technological development. OLED has the characteristic of being flexible, and many people believe that OLED TVs will be the future star of the television industry rather than LCD or plasma TVs. But recently, a group of 13 companies and institutions

Why LCD screens lose to OLED displays
Friends who are more concerned about the electronic product industry should be aware that LCD screens are becoming increasingly "unpopular", not to say that LCD screens are particularly poor. On the contrary, some people are still accustomed to the flat and comfortable appearance of LCD screens. The unpopularity mentioned here is relative to enterprises, as the popularity of OLED screens far exceeds our imagination. The inherent natural characteristics of OLED displays make the selling points of terminal devices more diverse, and LCDs are now difficult to catch up with. OLED screens were indeed a drawback in their early days, such as being too rich in color, having a lower lifespan than LCDs, and having sparse pixel arrangements (graininess)
