product line, expanding the Sony lineup of products for use

in digital still cameras.

The ACX312AK achieves a viewing

area ratio of 100% by setting the

overscan to 0%. This allows all of the

image taken by the CCD to be displayed

with nothing missing to prevent the loss

of critical images.

By adopting Sony’s TFT polycrystalline

silicon technology developed over many

years, the ACX312AK manages to pro-

Of our low-temperature polycrys-

talline silicon LCD products, the

ACX312AK aims to become a

de facto standard due to its

specialization for use in digital

still cameras. This LCD repre-

sents the crystallization of efforts

and technologies contributed by

many engineers, and we are

convinced that this device is

superior to other manufacturers’

LCDs, both in performance and

quality. I hope many digital still

camera developers will adopt this

product.

tional ACX300 Series products (2.0

type to 3.5 type) despite its ultrasmall

form. In particular, it includes up/down

and/or right/left inversion functions to

increase the degrees of freedom avail-

able in end product design. Further-

more, it achieves high contrast (200:1)

and high transmittance (8.6%), and is

at the top level of number of effective

pixels per unit area (115.4 dots/mm

in the ACX300 Series. As a result, it

provides smooth fine-grained images

with no apparent dots and a high pic-

ture quality. At the same time it can

contribute to reduced overall power

consumption in end product designs.

Sony provides the new CXA3572R

system IC, which was developed along

with the ACX312AK. This system IC

integrates the timing generator and the

RGB drivers on a single chip. The

CXA3572R supports both NTSC and

PAL, and accepts either Y/color differ-

ence or RGB signals as input. It includes

up/down and/or right/left inversion

functions to take advantage of the pan-

els’ features. Furthermore, it includes

power saving functions to reduce power

consumption in standby mode even

further. (See figures 2 and 3.)

The CXA3572R provides many advan-

tages over the conventional CXA3522R.

(See table 2.) First, the package has been

reduced in size from a 72-pin LQFP to

a 48-pin LQFP, thus cutting in half the

space taken by the IC on the printed

circuit board. This increases the degrees

of freedom available in end product

design. Second, the VCO has been

integrated on the chip, obviating the

need for an external oscillator circuit

and reducing the number of external

components required. The previously

required PSIG buffer is planned to be

integrated as well, allowing a further

parts count reduction. Furthermore,

since this 1.8-type device has the same

number of dots as the conventional 1.5-

type device, the same printed circuit

board can also be used for end products

that use a 1.5-type device, thus contrib-

uting to reduced design costs when

creating a line of end products.
