What exactly is OLED? How is it different from the currently popular LCD screen?

The original text of Oled is Organic Light Emitting Diode, which is organic light-emitting diode in Chinese. The principle is to sandwich an organic light-emitting layer between two electrodes. When positive and negative electrons meet in this organic material, they will emit light. Its component structure is simpler than the currently popular TFT LCD. OLED also has many advantages, such as its own light-emitting characteristics. At present, LCDs all need a backlight module (add a lamp behind the liquid crystal), but OLED will emit light by itself after being powered on, which can save the weight, volume and power consumption of the lamp (the power consumption of the lamp accounts for almost half of the entire LCD screen). Not only does it make the product thickness only about two centimeters, the operating voltage is lower to 2 to 10 volts, and the response time (less than 10ms) and color of OLED are better than TFT LCD, and it has the characteristics of flexibility, which makes its application range extremely wide. The font clarity is quite high. In addition, the OLED screen still displays clearly under the sun, which is different from ordinary color screens. For example, the current color screen mobile phone appears eclipsed in the sun.

12V LED and Distributed Constant Current Technology

We believe that previous companies, when designing LED packages , mostly considered the LED package itself, and paid less attention to the application design, which will be the future lighting package form. LED lamp manufacturers strive to develop power supplies to adapt to LED package forms. Too many packag

Analysis and research of three layouts of half-bridge resonant converters

近年来随着“节能减排、低碳社会”的持续深入建设，LED照明技术得到了长足发展，LED(Light Emitting Diode)是一种新型半导体固态光源，具有节能环保、长寿命等显著优点，因此，在全球能源日趋紧张和环保压力日益加剧的情况下，使用LED半导体照明是最佳选择。作为LED照明最核心的部分，驱动电路也为了适应不同市场不同要求而发展出众多的设计架构。不同的架构直接影响着光源的发光效率和常态寿命。从目前已研发出的驱动电路品种来看，输入整流-PFC调整-DC／DC-输出端分块已成为综合情况最合理的设计模式。但是这种设计模式更多的是按经验摸索而来，还缺乏对局部电路深入的分析。本文就根据主流设计电路结构，对驱动电路中重要组成部

Practical Consideration for Simplified Analysis of a DCM Boost Converter Driving an LED String

Part 1 of this article is dedicated to the theoretical analysis of a boost converter driving an LED string. This research was motivated by the need to stabilize the backlight driver loop for automotive applications. Since pulse width modulation (PWM) is used for dimming control, loop control is an important design co

High power LED package options - K1 lead frame or ceramic package

As the unit brightness continues to increase, LEDs are increasingly used in the lighting field. In order to continue to increase the brightness of LEDs, it is inevitable to increase the area and power of a single epitaxial chip, but this also generates high heat. Before ceramic packaging became popular, the K1 pa
