A transformer is an electrical device that is used to transfer electrical energy from one circuit to another through electromagnetic induction. It consists of two coils of wire, called the primary and secondary coils, which are wrapped around a common iron core. When an alternating current is passed through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil. The voltage in the secondary coil can be stepped up or stepped down depending on the number of turns in each coil. Transformers are used in power transmission and distribution systems to step up the voltage for long-distance transmission and step it down for distribution to homes and businesses. They are also used in electronic devices such as power supplies and audio amplifiers.

In recent years, as more color TV brands have entered the OLED market, OLED TVs are expected to maintain their strong presence in the high-end television segment. In 2018, it was forecasted that OLED TV shipments would reach a record high of 2.5 million units, showing a significant rise from 1.5 million units in 2017. This growth is driven by increasing consumer demand for premium display technologies.
According to industry insights, this year’s OLED TV market has seen active promotion from global players like Sony and Skyworth, with their products receiving positive feedback from consumers. The shipment performance of OLED TVs has exceeded expectations, despite some challenges related to color degradation over time. However, OLEDs still outperform LCDs in terms of color accuracy, contrast ratios, and slim design, which keeps major TV manufacturers interested in OLED development.
While QLED technology offers better color saturation and longer lifespan, it struggles with maintaining consistent brightness due to low external quantum efficiency, making commercialization difficult. As a result, OLED remains a more viable option for high-end displays.
In terms of pricing, the manufacturing cost of OLED panels has been steadily decreasing. For example, a 55-inch ultra-high-definition OLED panel saw a 55% price drop between the first quarter of 2015 and the second quarter of 2017. Compared to similar-sized LCD panels, the price gap shrank from 4.3 times to 2.5 times. By the first quarter of 2021, it's estimated that the cost will further decrease to around $242, bringing OLED and LCD prices much closer together.
This drop in panel costs directly impacts the final retail price of OLED TVs. According to AVC data, the average price of Chinese OLED TVs fell by 50% from 2014 to 2017 as panel prices declined. Domestic brands, in particular, have made OLED TVs more affordable, helping to increase their adoption among consumers.
Moreover, Chinese panel manufacturers are starting to invest heavily in the OLED TV panel market. BOE, for instance, has successfully developed OLED panels and is accelerating mass production. China’s first self-developed OLED TV from Skyworth uses BOE’s technology, signaling a shift away from reliance on imported panels.
With growing production capacity and increased competition among panel makers, OLED TV panel output is expected to rise rapidly. This will likely lead to further price reductions, pushing OLED TVs into a broader consumer market. It seems that the era of widespread OLED adoption is just around the corner.
