A high-resolution color screen has become an essential feature of mobile phones, handheld computers, and other portable devices because the user impression is particularly important.

This paper discusses various OLED technologies and bias power supply circuits.

Several cutting-edge display technologies are gaining popularity, such as emerging OLED displays. These displays boast outstanding features, including high contrast ratios, rapid response times, and wide viewing angles. As with our other advancements, manufacturers are implementing various solutions for OLED displays using different LED materials, control methods (active or passive matrix), and drive technologies (current or voltage). china oled Along with this, our company offers a range of bias supply circuits. In this article, we will explore the various OLED technologies and corresponding bias power supply circuits. It's worth noting that the choice of OLED technology and drive method can also impact the need for a power supply circuit. The key challenge for engineers is to select the most suitable power supply circuit to support battery-powered portable devices and specific OLED displays.

OLED technology's advantages and disadvantages

OLED displays offer a range of benefits, such as wide viewing angles and vibrant color saturation, that surpass other technologies like liquid crystal displays. Additionally, they have the advantage of being self-lit and do not require backlighting, resulting in quicker response times for multimedia usage compared to LCD displays. Currently, the market offers two types of organic light-emitting diode materials: small molecules and light-emitting polymers. These technologies have very similar circuit parameters to standard LEDs; their brightness is determined by forward bias current for LEDs and voltage for LCD pixels. Another key benefit of OLED displays is that they can utilize existing substrate technology, identical to that of thin-film transistor (TFT) liquid crystal displays. This means that active matrix organic light-emitting diode displays can use either amorphous silicon (a-Si) or low-temperature polycrystalline silicon (LTPS) TFT substrates.

In OLED technology, one of the main challenges is its longevity, which is limited by the fact that RGB colors fade differently, so it is necessary for all three primary colors to emit the same brightness at the same time, especially when the majority of the display is white. Due to these color restrictions, monochrome displays became the first to appear on the market, and full-color displays were shutting down most of the product's lifecycle.
