Transmissive 6.3 cm (2.5-Type) 154k-Dot System
Display with LED Backlight for Digital Still Cameras
Features Narrow Frame and 8-Bit DAC
ACX392AKM
The ACX392AKM is a built-in driver 6.3 cm active matrix transmissive color LCD module that uses low-temperature
polycrystalline silicon transistors. This is an integrated drive circuit LCD panel that integrates an 8-bit DAC circuit
using system on glass technology. It includes all the required drive circuits and requires no external ICs.
The ACX392AKM adopts a direct interface system that supports direct connection to a DSP, and at the same time as
reducing the number of peripheral components, it also contributes to reduced power consumption.

Direct Interface Support
The ACX392AKM is an integrated drive
circuit LCD panel implemented using system
on glass technology. It includes all the required
drive circuits and requires no external ICs and supports direct connection to a DSP to achieve
a significant reduction in peripheral
components.
Increased Resolution
By increasing the pixel count from 480 × 240
to 640 × 240 in the same display size as
existing panels, the ACX392AKM can now
display 320 × 240 input signals as an integer
multiple thus resolving the problem of distorted
characters.
8-Bit RGB Serial Data Transfer
Existing system displays use a 6-bit DAC plus
FRC drive to achieve a simulated 7-bit
equivalent bit depth. In this product, Sony has
developed new circuits that achieve full 8-bit ×
RGB (16.77 million colors) display to
contribute to improved picture quality.
Integrated LED Backlight Module
The ACX392AKM includes a dedicated
backlight, which contributes to increased
flexibility in end product design.
The included LED backlight achieves a power
consumption level of 64 mW at a luminance of
250 cd/m2, allowing the ACX392AKM to achieve a 124 mW level as an integrated
module.
Image Coverage: 100%
With digital still cameras, it is necessary to
verify all pixels that were (or will be) captured
without any pixels being left out of the
displayed image. This panel supports an image
coverage of 100%.
Up/Down and/or Right/Left
Inversion Function
Since there are now digital still cameras that
allow the monitor to be rotated, the
ACX392AKM provides up/down and/or
right/left inversion function that can be
controlled with just serial signals. This provides
a high degree of flexibility for end product
designs.

By developing new RC DAC and sample-and-hold circuits, we were able to achieve
a full 8-bit 154k-dot display with the same
frame width as the existing 6-bit 115k-dot
system displays.
