Advanced displays are becoming an important feature of today's consumer electronics. BOE displays Seeing these new displays in action often strengthens the user's impression of the product, which will ultimately determine how successful the product is in the market. User impression is particularly important for mobile phones, handheld computers and other portable devices, so the high-resolution color screen has become an essential feature of these products.

Various OLED technologies and appropriate bias power supply circuits are discussed in this paper.

A variety of new display technologies are expanding their market share, including some emerging OLED displays, oled manufacturer which have extremely high ratio, fast response time and wide viewing angles. As with our other new technologies, manufacturers are evaluating and manufacturing different solutions using a variety of different LED materials (polymers or small molecules), active or passive matrix control, current and voltage drive technologies, and the company's different bias supply circuits. This article will discuss the various OLED technologies and the appropriate bias power supply circuit, and the choice of OLED technology and drive method will also affect the demand for power supply circuit. The challenge for engineers is to select the most appropriate power supply circuit to support the needs of battery-powered portable devices and specific OLED displays.

Advantages and disadvantages of OLED technology

Wide viewing angles and good color saturation are the main advantages of OLED displays, which are far superior to other technologies such as liquid crystal displays. In addition, the OLED display is also a self-lighting technology, so it does not require backlight lighting and can provide faster response times than LCD displays to support multimedia applications. At present, there are two kinds of organic light-emitting diode materials on the market, which are small molecules and light-emitting polymers; The circuit parameters of both technologies are very similar compared to standard leds. Their luminous intensity is determined by the forward bias current of the LED, and the pixel brightness of the LCD is determined by the voltage applied to the pixel. Another advantage of OLED displays is that they can use existing substrate technology, which is exactly the same as thin-film transistor (TFT) liquid crystal displays. Active matrix organic light-emitting diode displays can use amorphous silicon (a-Si) or low-temperature polycrystalline silicon (LTPS) TFT substrates.

One of the main challenges with existing OLED technology is its longevity, which is limited by the fact that RGB colors fade at different rates, especially when most of the display is white, it requires all three primary colors to emit the same brightness at the same time. Because of these color limitations, monochrome displays became the first to appear on the market, and full-color displays for application-only displays were shutting down most of the product's life.
