T4 technology enhances TFT display readability

GPEG has announced that its Transflective TFT Technology (T4) enhances TFT readability in handheld display devices used in bright sunlight and high ambient light conditions.

With T4, design engineers have access to an easy-to-read, high-contrast, wide-viewing-angle TFT display where the displayed image actually gets brighter under high ambient light conditions, especially direct sunlight.

To ensure complete flexibility under all ambient light conditions, GPEG has incorporated an efficient LED backlight that ensures the TFT display exhibits the same viewing characteristics when the ambient light reduces.

The first of GPEG's T4 displays is a compact 3.5in QVGA (320x240) TFT with a viewing area of 71.0 x 54.0mm and an overall thickness of only 2.93mm.

The display has a wide viewing angle 55/55 L/R 45/45 U/D and will display 262K colours using the six-bit RGB or SPI interface.

The low-power LED backlight provides a surface brightness of 90cd/m2, which ensures good readability in low ambient light conditions.

GPEG has included the option of a touch screen for easy operator interface; currently this is a resistive type, however, full multi-touch projective capacitive will be available within two months, which supports all the functionality of modern touch technology, including zoom, swipe, pinch and so on.

The T4 Transflective TFTs from GPEG are said to overcome the existing constraints of TFTs, enabling designers of handheld equipment, medical instruments and any display device that needs to be used in sunlight, to have a high-visibility colour display that will enhance product performance.
