hello. This is Technologytodaynow. When Apple unveiled its M4 MacBook Pro on Oct. 31, it has received positive reviews from consumers for its improved performance and upgrades to basic specifications. In particular, it has received positive responses from consumers due to the M4 chip’s excellent performance, price stability, and increased memory capacity.
However, Apple’s official announcement also reported improvements to the display technology, which is not mentioned, so we’ll look at the M4 MacBook Pro upgrades that aren’t revealed in this article.
Little-known M4 MacBook Pro upgrade
Equipped with new display technology using quantum dot film
According to Ross Young, CEO of Display Supply Chain Consultant (DSCC), the newly released M4 MacBook Pro features new quantum dot film technology. Apple has previously used KSF phosphor film, but this time it adopted quantum dot film, which is more efficient and has excellent color expression.
The reason why Apple has used KSF phosphor film so far is that it has been considered more economical because it contains cadmium, a toxic substance. When Apple started supporting P3 wide color on the iMac in 2015, Apple executives reviewed the Quantum Dot LED display, but the plan was canceled due to cadmium issues.
Advantages of Quantum Dot Films
However, the quantum dot film adopted by Apple this time is said to be a greatly improved film.
The advantages of the improved quantum dot film are as follows.
- Cadmium-free eco-friendly technology: the use of cadmium, which has been a problem with traditional quantum dot films, has been eliminated.
- Larger color areas: richer and more accurate color representation than before.
- Improved motion performance: Smoother transitions on fast-moving screens.
Quantum dot technology has already been applied to display products such as QLED and QD-OLED, and is widely known for providing excellent image quality and color.
M4 MacBook Pro with Improved Brightness
The M4 MacBook Pro’s display on board has significantly increased brightness from 600 nits to 1000 nits in SDR (standard dynamic range) mode. This allows users to experience clearer and more vibrant screens, especially for professionals working on photography and video.
Why Apple Didn’t Highlight New Technology?
Ross Young believes that Apple has not officially announced the introduction of quantum dot films on its M4 MacBook Pro displays because it does not want to disparage most Apple products except the MacBook Pro because they are currently equipped with KSF solutions. This is because promoting new technologies could reduce the value of existing products. Since there are also monitor products such as Apple Studio Display and Pro Display XDR, it seems to be a decision to prevent competition among its products and protect the brand image.
