Display Taiwan was in full effect today and there were a few gems on the show floor that we uncovered, the first that we found the most intriguing was a tranflective display that was extremely similar to Pixel Qi.
Here is what we know about the CPT screen so far, it offers 1366 x 768 screen resolution with a pixel pitch of 0.16305 x 0.16305, color gamut of 60% MTSC, 200 brightness, a contrast ratio of 400, reflectivity of 5 and viewing angle of 170/170. This is all a little techy even for me so what is important to note is the wide viewing angle, power savings and that it is sunlight readable.
We are still waiting on exact TPD numbers but said that it will draw 50% less power. Comparted to Pixel Qi this isn’t that great since their screen draws 0.5 when the backlight is off.
The biggest difference between CPT and Pixel Qi is that CPT is a display manufacturer so they do not have to find someone to make their product. The rumors around Taiwan have been that Pixel Qi is having trouble finding a fab, Pixel Qi says they have the means to produce, but the proof is in the pudding and we wait for either company to come to market in products. We really do hope this happens soon as we need a solution for computing outdoors.
I will update this article with the TDP for the CPT screen when i get it, but for a comparison here is the Pixel Qi video we did comparing this display to AMOLED screen on the Nexus One.
*** UPDATE***
The total Module Power of a normal 10.1″ transmissive LCD panel is about 3.2 watts,
where the Backlight Power is 2.2 watts and panel signal power is 1 watt.
Not quite as low as Pixel Qi but the numbers aren’t bad.

There's approx. dozen different videos trying to show how great is Pixel Qi/transflective technology. Virtually all of them show very little of the alleged effect. The reasons are quite obvious:
1. When choosing your camera man, don't use one with trembling, shaky hands. Or the one who cannot stand still for more than 5 minutes. Better put the camera on a tripod. Naturally, the presenter must exhibit the same virtues too, and if not (like she/he needs to dance a lot when talking), let him/her put the object on the stand, so the angle stays the best glare-less during the whole shot. Except for mere seconds to show critical (170+ degrees) viewing angles. Now you can dance and gesture away Thank you.
2. The shots made under direct sunlight are obviously the best demonstration of the principle. If in lack of natural sun, just use the strongest light bulbs you can find, plus virtually centimiters from the screen. Thank you for this (unshot yet) footage, too.
3. For the particular “CPT” shot, when talking about perceived irregularity of font rendering in transflective mode, you again may want to put your camera on the stand from the best (glareless) angle, the use the macromode/zoom carefully, slowly, so the AF picks correct distance. However, the modern font rendering technologies explicitly use color in their font hinting routines, so when the color is out the font outlines may become distorted/blurred at smaller pointsizes if the manufacturer forgot to switch the font renderer into the monochrome mode when the backlight is off.
4 The emerging transflective technology begs for making good (staged according to simple rules above) side by side comparisons of Pixel Qi, Liquavista, Bridgestone, whatever, and iPad, plus between transflective pairs. Any potential transflective screen manufacturer should be asked whether their technology is compatible with IPS, OLED, 4-color, 3D displays.
I’ll be sure to get all of those manufacturers to give me a sample to do a side by side. . .
I’ll take these notes with me and be sure to try to learn to ask them in Chinese.
Thanks for your input and I’m glad that you appreciate the free content we provide.
