Issue : TFT & AMOLED screen woe ?

encoreppc — Wed, 05 Aug 2009 03:59:08 +0000

Brandon Miniman from pocketnow.com highlight this issue during his comprehensive Omnia 2 review. He was claiming the Omnia 2 (AMOLED) has poor visibilty directly under sunlight.

* Im using this pictures as example, this is not Samsung Omnia 2

As far with my experience on OLED (1st gen of AMOLED) screen on my previous DAP (digital portable audio), its quite hard to see under direct sunlight. Its occurs when the screen blackness not much reflect the sunlight which reduce contrasity. Everything on screen is fade and its a bit troublesome. Its important to see incoming call, appointment and on the go. However I dont think most people would use and texting under sunlight. So you might need to take cover for better angle.

AMOLED or not, most touchscreen PDAs has common problem since TFT.

So the Zune HD is finally reveal. Alot of speculation this Zune HD will have similar interface with Windows Mobile 7 screen. Most likely is WM 6.5 today screen with smooth animation. Does Zune HD imitate WM 6.5 today screen or vice versa ?

I think Zune Hd present small part of WM7. The touch screen quite sensitive, and likely perform as well multitouch screen (perhaps its ready for it)….

Introducing – Qualcomm Snapdragon

encoreppc — Wed, 18 Mar 2009 03:13:54 +0000

Frankly, when anyone mentioning Qualcomm devices for reference, Iv no idea why I always imagining ’s-u-c-k-s’ in my mind. Previously HTC release lots of Qualcomm devices like Diamond, Touch Pro and Touch HD. With the VGA screen glory and ‘gorgeous’ looked, Qualcomm itself being culprit due poor performance involving 2D,3D graphic capabilty and video playback

However, the snapdragon platform preview in last MWC (Mobile World Congress) might change my view onto Qualcomm reputation. But was it ?

Specifications

Well it looks great, but I see they NOT mention about 2D drawing acceleration… Its important for smoothness screen scrolling, UI screen drawing and 2D gaming.

Combine a 1GHz processor core, our sixth generation DSP and 3G connectivity with ultra-low power consumption to create new mobile devices with the performance to revolutionize the world of mobile computing. The Qualcomm Snapdragon platform empowers a new generation of Pocketable Computing Devices (PCDs) and Mobile Computing Devices (MCDs) that deliver real-time ubiquitous communication, high performance multimedia, location-aware content, full Internet browsing and productivity applications, all with the lowest levels of power consumption for all-day battery life

-Qualcomm

And the benefits ?

Day-long battery life
Ubiquitous, real-time connectivity: WWAN, Wi-Fi® and/or Bluetooth® technology
Rich Internet experience with full Web browsing
Access to real-time “personalized” location-aware content with built in GPS
Streaming and playback of locally stored HD video content
High performance 3D UIs, games, maps and more
High-quality still pictures and video clips

Most current winmo devices already ’a day long’ battery life. Perhaps is offer lower battery consumption. Taking example from Toshiba TG01, its performance is promising (I hope)

Articles – Wide Resolution or Standard

This is good reading for choosing between VGA (640 x 480) vs WVGA 800 x 480) resolution. This articles post by my friend ‘Baronic” from lowyat.net PDA subforum.

With a Wide resolution device, whether WVGA or WQVGA, these games or applications no longer function at all, or if they do, leave a wide black gap or even worse, you could see the background of your Today screen -baronic.

This articles is highly recommended, kudos Baronic

Articles – HTC Diamond variant graphics performance issues!

encoreppc — Wed, 03 Dec 2008 01:26:50 +0000

Oh mine, HTC why you still developing brainless devices ? DSK from WMPowerUser.com discussing a matter of HTC variant facing similar issue like Kaiser/ Tytn. A lots of VGA enthutiast know that HTC Diamond variant doesnt fully utilize its GPU, but actually THERES MORE;

The fact is that the old X-scale intel chips had special MMX registers to speed up various things, including video decoding, which the Qualcom chips lack. If your codec cant take advantage of for example the mp4 decoding built into the qualcom chips then you will never benifit, even if you had all the drivers in the world.

HTC Diamond, Pro and HD is in the same family. Its believe the Touch HD users user will face same problem because alot of them expect to uses as multimediaplayer.

Gizmodo – Browser Battlemodo (FAILED)

encoreppc — Fri, 21 Nov 2008 01:59:05 +0000

Matt Buchanan from Gizmodo is making comparable review about browser usabilty using PDA’s. But when he commenting with WM base browser performance review, he’s akind biased towards WM platform. You see, comparison isnt fair due mixed of touchscreen and smartphones devices. Of course comparing iphone Safari browser with Samsung Epix WM smartphones that would make iPhone is alot better.

Okay what about Opera 9.5 ? how come youre so outdate and missleading

By the fact Opera 9.5 for Windows Mobile is ultimate desktop rendering capable browser, and Skyfire does too.
