It's being reported today that Samsung Display started placing orders for 8G OLED equipment for IT use from domestic equipment makers last month, but orders for evaporators, which take the longest time to manufacture equipment, have not yet been placed. There is a prospect that Samsung Display will place an order for an evaporator from Canon Talkie in Japan when Apple's OLED MacBook specifications become concrete.

Apple plans to apply OLED to MacBooks starting with the release of the first OLED iPad next year, but the OLED MacBook specifications have not yet been specifically determined. Samsung Display can place an order for an evaporator from Canon Talkie by reflecting the size of the 8th generation glass plate optimized for the size of the MacBook only when the specifications of the OLED MacBook are materialized. It is known that Apple plans to make additional decisions about the OLED MacBook after seeing the market reaction after the release of the OLED iPad.

Apple’s OLED MacBook Air will be a Single Stack method with one light emitting layer while the OLED MacBook Pro will have a Two Stack design.

One of the delays for MacBook's with OLED displays is the current economy, but there could also be a technical reason. The Elec's report noted that the specifications for the displays are not yet concrete.

One of the known issues with OLED displays is burn-in and Apple was granted a patent relating to a solution for this yesterday by the U.S. Patent Office. This could be one of the last specifications to be nailed down prior to giving Samsung the green light to proceed with OLED displays for future iPads and MacBooks.

Apple's patent relates to image data processing and compensating for pixel burn-in/aging of pixels of an electronic display.

Numerous electronic devices—including televisions, portable phones, computers, wearable devices, vehicle dashboards, virtual-reality glasses, and more—display images on an electronic display. As electronic displays gain increasingly higher resolutions and dynamic ranges, they may also become increasingly more susceptible to image display artifacts due to pixel burn-in.

Apple's patent relates to identifying and compensating for burn-in and/or aging artifacts on an electronic display.

Burn-in is a phenomenon whereby pixels degrade over time owing to various factors, including the different amounts of light that different pixels may emit over time. For example, if certain pixels are used more frequently than others, or used in situations that are more likely cause undue aging, such as high temperature environments, those pixels may exhibit more aging than other pixels. As a result, those pixels may gradually emit less light when given the same driving current or voltage values, effectively becoming darker than other pixels when given a signal for the same brightness level. As such, without compensation, burn-in artifacts may be visibly perceived due to non-uniform sub-pixel aging.

In some embodiments, circuitry and/or software may monitor or model a burn-in effect that would be likely to occur in the electronic display as a result of the image data that is sent to the electronic display. For example, statistics surrounding the utilization of the pixels of the electronic display and/or environmental conditions (e.g., temperature) during operation of the pixels may be analyzed and tracked (e.g., via a burn-in history map). The statistics may then be used to derive gain maps for adjusting image data before it is sent to the electronic display to reduce or eliminate the appearance of burn-in artifacts on the electronic display.

Burn-in gain maps may be derived to compensate for the burn-in effects based on the tracked operation of the active area pixels using the panel-specific aging profile. In this way, the pixels of the electronic display that have suffered the greatest amount of aging will appear to be equally as bright as the pixels that have suffered the least amount of aging. As such, perceivable burn-in artifacts on the electronic display may be reduced or eliminated.

Apple's patent FIG. 8 below is a block diagram of the burn-in compensation (BIC) and burn-in statistics (BIS) collection block.

Apple's patent FIG. 12 above is a flow diagram of an example process using a panel-specific aging profile to determine compensated pixel values.

Apple's iPad and MacBook Pro models are some of the highest priced devices on the market. The last thing Pro fans will want to experience is display burn-in issues. Including a solution for this issue in their first-gen OLED based Pro iPads and MacBooks is paramount.
