CPT is using Clairvoyante’s PenTile RGBW technology to manufacture 4.0″ and 7.0″ TFT LCDs that have a pixel format of 800 x 480 (typically called WVGA). The two panels are geared for UMPC-type devices that would do good with high resolutions, wide aspect ratios and low power consumption.
With the PenTile RGBW, there are 1600 source drivers compared to 2400 if a typical RGB Stripe display technology was used. Gate drivers remain the same at 480 for both. Transmittance is upped to 10.0% from a typical 5.5%. CPT is using 7 LEDs (420mW) to generate 400 cd/m2. The RGB stripe technology using the same 7 LEDs will generate much less brightness at only 220 cd/m2. Color gamut does not improve but is at a respectable 60% NTSC.
