CPT is the new kid on the transflective screen scene that is dominated almost exclusively by Pixel Qi right now. Of course, these two are not the only players in this segment as Liquavista, Mirasol and Bridgestone too are promising better and more exciting display technologies for future tablet or e-reader products. But as things stand now, its Pixel Qi that leading the pack with CPT showing its willingness to join the race in right earnest.
Coming to the actual screen, it’s a 1366 x 768 resolution transflective panel that its makers claim has a pixel pitch of 0.16305 x 0.16305. CPT further said their display panel has a contrast ratio of 400, reflectivity of 5 and viewing angle of 170/170. The new CPT display panel can boast of a color gamut of 60% MTSC while also having a brightness of 200 nits, all this while being 50 percent more efficient than a regular LCD display. These figures, CPT says translates to a brighter display while having a higher contrast ratio and an easy readability even in bright sunlight conditions.
However, in spite of all the high words, the display still seems to be a notch below that of the Pixel Qi screen and its energy efficiency is not in the same league as that of the former as the Pixel Qi technology is known to be 5 times less power sapping with backlight turned off than the CPT screen that promises to bring down power consumption by only 50 percent. While a 50 percent less power drawn from the battery can’t actually be termed bad but what can be said is there is still scope for development.
But there is one area where CPT scores comprehensively over Pixel Qi and it is in them being already a screen manufacturer. So producing the new transflective screen won’t be much of a problem for CPT. Pixel Qi is however is not as fortunate and latest reports is pointing to them having difficulty on zeroing in on a manufacturer that would give shape to their 3Qi screens.Pixel Qi is a more refined technology but if its products are nowhere in the market, than it comes to a naught. And it is where CPT has a distinct upper hand
Meanwhile, transflective screen are unique in that they include the best of an E Ink screen while also allowing full color displays. They can be just as easy to read indoors as it is out in the sun. The backlight can be shut off when reading outdoors or in bright light conditions thus saving considerably more power than an LCD screen.
More on this will be covered here as with all the current e-reader news.
