* Transmissive 8.8 cm (3.5-Type, Wide)
920k-Dot Color LCD Panel Features the
VSPEC III
TM Wide Viewing Angle LCD Mode

ACX391AKB

The ACX391AKB is a built-in driver diagonal 8.8 cm active matrix panel that uses low-temperature polycrystalline silicon transistors.
This panel features ultrahigh resolution (213 ppi) and provides a detailed and smooth display.
It also provides improved visibility from all viewpoints by adopting VSPEC III
TM, a new wide viewing angle LCD mode.
This panel allows direct connection to the DSP using a direct interface method and achieves a significant reduction in the number of peripheral components.

* Direct Interface (8-bit RGB Serial)
The driver IC is mounted on the panel itself, and the interface is 8-bit digital and achieves the expression of 16.77 million colors.
Furthermore, NVM is also included and the Vcom adjustment value is written prior to shipment. Thus there is no need for Vcom adjustment in end products.
* Increased Resolution
This panel features ultrahigh resolution (213 ppi) and provides a detailed and smooth display. The number of dots displayed is 640H × 3 × 480V = 921,600 dots.
* Wide Viewing Angle LCD Mode Adopted
This device adopts a wide viewing angle mode based on Sony’s new VSPEC IIITM technology. Visibility is increased at every viewing position and the panel achieves a viewing angle of 160° in the up/down and right/left directions.
* Thinner Panel Module
While the ACX391AKB is a 3.5-type wide aspect ratio panel, Sony has reduced the thickness of the glass used to hold the panel module thickness to under 1.01 mm. This can contribute to increasing flexibility in end product mechanical design.
* High Contrast
The ACX391AKB achieves the high contrast of 800:1 by adopting the VSPEC IIITM technology. In conjunction with the increased viewing angle characteristics, this creates a high picture quality panel.
* Up/Down and/or Right/Left Inverse Display Function
Since there are now digital still cameras that allow the monitor to be rotated, the ACX391AKB provides up/down and/or right/left inverse desplay function that can be controlled with just serial signals.
This provides a high degree of flexibility for end product design.
