In November, we introduced you to our new blog series, a sequence of posts dedicated to going behind the scenes of Xperia, introducing you to the people who work together to bring our innovative smartphones to life.
Today we’d like to introduce Takao Yagi, Display Engineer at Sony Mobile. After five years at the heart of Sony’s Bravia TV department, Takao Yagi focus took a shift towards mobile technology, and since 2004 has been a core part of the team delivering some of the world’s leading mobile displays.
Together we discussed his inspiration & passion for Sony, his BRAVIA TV experience & all things mobile.
What did you want to be when you were a kid?
I didn’t have a lot of time to think about my future when I was young. I was too busy playing, working & living! There just wasn’t enough time in-between to plan that far ahead.
How did you start working at Sony?
Since I was really young, Sony had always been my favourite brand – my ambition grew from there. Once I knew that Sony was a company I wanted to work for, I went out and worked hard to make it happen.
How long did you work on BRAVIA TV’s and how long have you worked at Sony Mobile?
I worked 5 years for BRAVIA TV & I’ve been a part of Sony Mobile since 2004, so 10 years now.
Were there particular things you learned that have made a difference to the development of Xperia displays?
When compared to TV? Yes, the biggest difference of all being power saving. It’s also important to remember that there is a difference in contents – what I mean by this is that when it comes to television displays, resolution is always fixed and the focus is on chasing super beautiful image quality. This isn’t the case with mobile, instead here the content is unspecified and so you want to balance beauty with power.
How do the displays of a television and a smartphone screen overlap, e.g. materials, techniques?
Understanding the human element of display technology is the same in both XPERIA and BRAVIA – take colour for example. When people think of a red rose, they imagine it being much redder than it really is and the same when you think of a blue sea. We need to reflect this in our displays. But when it comes to human skin, people want that to be an accurate reflection so that it looks real and genuine so this too needs to be incorporated. Understanding how people engage with their displays is an important insight that’s relevant whether it’s a TV or a smartphone.
What are the different restrictions that you face when creating displays for TVs and smartphones?
As I mentioned before, power saving is the biggest restriction due the different display nature between the devices. Again this is followed by the change in contents.
What’s been your greatest achievement since working on the Xperia series?
The greatest achievement for me is always the next Xperia I’m working on. It’s an achievement in itself delivering new devices that contain extraordinary engineering features.
That’s all from Yagi-san, keep your eyes peeled for another ‘People behind the Xperia series’ next month.
