(Hong
Kong - 08 Oct, 2004) - With respect to the
increasing demand on TFT module for smart phone
application, Solomon Systech Limited launched
today their first single chip TFT LCD driver IC
SSD1278 which supports 176x220 (QCIF+)
resolution and 262K color smart phone system.
SSD1278 is a single chip solution that includes
gate/source driver blocks and power management
circuit. SSD1278 with RGB interface, which is
supported by common image processors/graphic
controllers, is a perfect solution for speedy
data transfer when using CMOS/CCD camera in the
smart phone system.
SSD1278
is the smallest (with only 20.9 x 1.4mm²
die size) and the simplest solution commercially
available for QCIF+ resolution in the amorphous
TFT display. The advantages of the small die
size are not only in cost reduction of the
module but also achievement of compact design of
the phone. The smaller die allows thinner
contact ledge at the LCD module and therefore
smaller overall physical size. Besides, the
advanced design technology from Solomon Systech
achieves low power consumption in the TFT LCD
module system. This is one of the essential
factors in all portable systems. In an actual
measurement of a 1.9", 176x220 QCIF+
display module using Solomon Systech's TFT
driver SSD1278, the module power consumption at
262k color, 60Hz frame frequency and line
inversion is only 8mW, while the power
consumption at frame inversion is even 7mW.
These low power consumption values enable
Solomon Systech to become one of the most
competitive TFT LCD driver suppliers in the
market. |

The
Powerful Smart Phone System with RAMless driver
|
|
The
mobile phone has been improved by adding colorful
display, video clip, camera function and PDA features.
In order to cope with the demand on features
enhancement, a new innovative mobile phone system has
been created. Nowadays, the smart phone system does
not only include the MCU and DSP blocks but also an
image processor that can help on the MPEG4
acceleration, JPEG Codec, 2D/3D graphic engine and so
on. As image processor has already sufficient display
SRAM on chip, only a RAMless driver like SSD1278 is
needed in order to optimize the smart phone system.
This structure eliminates the duplication of RAM at
the driver IC and improves overall efficiency and cost
of the system. Therefore, SSD1278 is the most suitable
RAMless solutions for a smart phone system and this
would be the trend in the future handset market.
