SSD2080M – Enables New Technology For HD Smartphone Applications
Ideal Solution for WXGA High-Definition Metal Oxide Panels
(Hong Kong – 26 July, 2013) Solomon Systech today announced the launch of SSD2080M, a liquid crystal display driver supporting high-definition Metal Oxide panel technology. It is an ideal solution for HD smartphone applications.
The smartphone market has expanded exponentially in recent years, with an increase in display size and enhanced image quality and definition. Most of the HD720 (720RGB x 1280) solutions in the market today deploy a-Si, AMOLED or LTPS technologies. However, a-Si technology incurs relatively higher power consumption which is undesirable for portable smartphone devices, while AMOLED and LTPS solutions are constrained by their relatively high costs.
SSD2080M is an ideal solution for high-definition Metal Oxide panels. Apart from allowing the use of fewer mask layers in panel production compared to LTPS/AMOLED which helps reducing production costs effectively, and that it can achieve up to 350ppi, SSD2080M has the following key competitive features which set it apart from other solutions:
(1) Reduce Power Consumption by “Frame Skipping” Technology
The unique bistable feature of metal oxide panel facilitates the retaining of display quality with low frequency operation. SSD2080M, with its “frame skipping” technology, can help largely reduce the power consumption of metal oxide panels. The average frame frequency of an operating a-Si panel is 60Hz for ordinary application. SSD2080M, with its advanced function of “frame skipping”, can drive the average frame frequency of a metal oxide panel to as low as 1Hz without sacrificing the display quality. In the case of driving an average frame frequency of 30Hz, SSD2080M enabled metal oxide panel can reduce the average display power consumption by 25%.
This “frame skipping” function on metal oxide panel is extremely important for high-end smartphones with high power consumption applications. Besides, SSD2080M has a small amplitude interface (MIPI-DSI) to transfer mass data at a high speed and to support low-power operation.
(2) Support Wide Range of Resolutions and Panels
To cater to different customers’ needs, SSD2080M supports a wide range of resolutions including:
Source x Gate
|WXGA||800 RGB x 1280 dots (Windows Smartphone)|
|HD768||768 RGB x 1280 dots (Android Smartphone)|
|HD720||720 RGB x 1280 dots (Android Smartphone)|
|DVGA||640 RGB x 960 dots|
|QWERTY||640 RGB x 640 dots (QWERTY Smartphone)|
(3) Enable Display of Vivid Images
With SSD2080M, images are displayed by the newly developed Display Enhancement Engine, which enables enhancement of color (saturation), contrast, sharpness and sunlight readability; while the color correction function makes the images as vivid and clear as those adopting high cost AMOLED and LTPS displays. The high electronic mobility of metal oxide also helps reduce TFT cell size, thereby increases the light transmission rate, making the display looks much brighter and sharper.
(4) Enable Metal Oxide Panel to Achieve Narrow Bezel Design
SSD2080M is highly integrated with a competitive die size. Not only that it integrates the advanced GIP circuit to reduce the number of gate control signal, it also operates with a 4 lane MIPI-DSI that requires only 4 pairs of data lane and 1 pair of clock lane to achieve high speed data transfer of 2.2 Gbps/4 channels, which largely reduces pin count from the controller.
The compact design of SSD2080M together with the high electronic mobility feature of metal oxide panels enable modules with narrow bezel design (~1mm), which helps to maximize the display area of the screen. This makes a perfect match with the current trend of smartphone design.
