Smartphones have become an integral part of our lives, and one of the most significant technological advancements that revolutionized the industry was the introduction of the iPhone by Steve Jobs in 2007. The original iPhone boasted a groundbreaking LCD multi-touch panel that allowed users to interact with the device like never before. While LCD touch screens already existed in cell phones, Apple’s innovation made people truly care about this technology.
Over the years, Apple has made significant improvements to their displays, with the iPhone’s usability and design evolving around the screen. From the early models to the iPhone 3GS, the phones featured a 163 pixels per inch (PPI) density. However, it was the iPhone 4 that introduced the “retina” display, boasting a doubled pixel density of 326 PPI. This pixel size remained constant for seven years, while advancements in LCD technology continued.
But now, Apple is taking a bold step forward with the iPhone X, departing from its faithful LCD screens and embracing a new technology: OLED. Enter Samsung, Apple’s secret supplier and arch-rival, who has been manufacturing OLED displays in their Galaxy smartphones for years. This collaboration marks the first time that Apple enthusiasts will experience OLED technology firsthand.
So, what exactly sets LCD and OLED displays apart?
LCD, which stands for liquid crystal display, utilizes liquid crystals that change molecular orientation when an electrical current is applied. This manipulation of light passing through the liquid crystal allows for display control. LCD panels require a backlight to provide illumination, with modern panels using LED backlighting for even lighting distribution.
On the other hand, OLED operates differently, with each pixel being self-illuminating through electrophosphorescence. OLED displays consist of two organic compounds sandwiched between an anode and a cathode. As an electrical current flows through, energy is released in the form of light, resulting in vibrant colors and true zero pixel values, leading to incredible contrast ratios.
Samsung has a near-monopoly on the OLED manufacturing market, producing 90% of the world’s supply and holding the majority of the patents. This dominance has forced competitors like Apple to source OLED displays from them to stay up-to-date with the latest technology. It’s worth noting that Apple has reportedly invested billions in Samsung’s competitor, LG Display, in an attempt to reduce their reliance on Samsung.
While OLED displays offer many advantages, they also have some limitations. One of the chief concerns with OLED technology is burn-in, which occurs when prolonged static images cause decay in the organic layers of the pixel. This can result in less brightness compared to surrounding pixels, leading to ghost images. Additionally, the cost of OLED panels can be significantly higher than equivalent LCD panels.
Despite these challenges, OLED displays are paving the way for exciting advancements in the world of technology. LG Display, for example, has developed a consumer OLED television that is only 2.57mm thick. Transparent OLEDs that can be integrated into glass panels are also under development, and various manufacturers are working towards foldable displays.
With continuous improvements, OLED displays have the potential to revolutionize the way we consume and view information. Websites on our phones will look better than ever, and the possibilities for display usage in various industries are expanding rapidly.
In conclusion, the collaboration between Apple and Samsung on OLED displays marks a significant shift in the smartphone industry. OLED technology brings vibrant colors, deep blacks, and improved contrast ratios to our devices. While there are challenges to overcome, the future of display technology looks promising. Exciting times lie ahead as OLED continues to evolve, opening up new possibilities for how and where displays are used in our everyday lives.
