What is an OLED display?

An OLED display uses a new technology called OLED (Organic Light Emitting Diodes). OLED screens are brighter, more efficient, thinner and feature better refresh rates and contrast than LCD or Plasma.

OLEDs are made by placing thin films of organic (carbon based) materials between two conductors. When an electrical current is applied, a bright light is emitted. Since the OLED materials emit light, a backlight is not required (unlike LCDs).

OLEDs in mobile phones

Mobile phones that boast OLED screens are rapidly becoming more prevalent, with over 500 million AMOLED screens annually - mostly to satisfy demand from mobile phones. Samsung has been using AMOLEDs in its high-end phones for many years, and most phone makers are also adopting OLED displays (including Apple, LG, Xiaomi, Huawei, Oppo, Vivo, Lenovo, Motorola, and others).

OLED displays are advancing quickly, and today smartphone AMOLED displays outperform LCDs in all parameters - except the price which is still at a premium.

DSCC: the OLED market will decline 13% in 2023, growth to resume in 2024

DSCC estimates that OLED revenues in 2023 will be $36.1 billion - down 13% from last year. Just a few months ago DSCC's forecast for 2023 was $38.9 billion. This is the second year that the OLED market is contracting. In terms of shipments, there will be a 5% decrease in 2023. Looking forward to 2024, DSCC sees the market starting to recover, as demand for IT displays, TVs and smartphones will increase.

Looking at specific markets in 2023, DSCC says that OLED smartphone shipments will remain flat, but will drop 11% in revenues - as the demand for higher-end flexible displays is lower than in 2022. The only positive is the foldable display market, where shipments will increase 33% in 2023 compared to last year. 2023 also experiences a big drop in demand for OLED TVs - DSCC sees shipments declining 31% in 2023. The same goes for laptop OLEDs - a 32% decrease in sales in 2023.

Apple cancels BOE's iPhone 15 panel orders, orders more displays from Samsung

In March 2023 we reported that BOE is developing smartphone OLED displays for Apple's iPhone 15 range, but it is facing technical hurdles, and Apple has yet to approve BOE's displays (the main problem seemed to be around the punch-hole and selfie camera and FaceID sensors).

Apple may use an MLA AMOLED display in future iPhone devices

According to reports from Korea, both Samsung Display and LG Display have approached Apple, offering to produce MLA (Multi-Lens Array) AMOLED displays for a future iPhone device. Applying the MLA panel will increase the light output, but will carry higher costs and may also reduce the viewing angles (or actually reduce the side-view brightness).

It is not clear what kind of effect will MLA offer in Apple's case. When LG applied MLA to its TV panels, the company says it improved the brightness by 60% (it also stated that viewing angles actually increased by 30%). Apple will not be the first one to apple MLA to smartphone displays - Samsung itself adopted MLA panels in some of its high-end models (Galaxy S Ultra phones) and so did some other vendors.

New laser repair system developed to fix AMOLED smartphone screen defects

An interesting video review shows a new repair system, based on lasers, that can fix defects in smartphone AMOLED displays. The system uses optical microscopy to find defects in operating OLED displays, and then a laser is used to fix the problems:

Such systems can be useful, but of course won't be able to fix all problems and defects in AMOLED displays, only ones that were caused by physical problems in conductive lines in the OLED module, that can be fixed by lasers. It will be interesting to see if these machines will truly find a place in the OLED repair aftermarket scene.
