14 DAY TRIAL // Samsung Electronics, the world's largest provider of liquid crystal display (TFT-LCD) panels, has recently launched, during a dedicated event - Display International Symposium and Exhibition(SID), San Francisco, California - a 3.5" LCD with embedded touch screen, and the first-ever 7" LCD powered by a single chip.
The first panel Samsung unveiled - the 3.5" LCD, or the 3.5" hTSP (hybrid Touch Screen Panel) - features a wide range of innovations, such as a sensor circuitry built in the panel, as all other LCD touch screens previously launched had a separate printed circuit board (PCB) attached to the top of the monitor.
The manufacturer explained the way in which these panels were made, using a dedicated technology - thin-film transistor (TFT) - which is used in all the company's facilities where LCS displays are produced.
The little LCD display is used in the production of several devices which necessitate a special touch screen like media players or even navigation terminals. The manufacturer said that, in the near future, these LCD panels will be used in smart phones, PDA phones, ultra-mobile PCs and other multimedia mobile products manufactured by a Samsung division or another similar producer.
This is why all mobile devices which feature such a 3.5" display can be produced in smaller sizes, maintaining in the same time the brightness and, most of all, the high contrast image displayed on the panel.
But the highlight of the SID event was the industry's first 7 inch single-chip LCD display, which boasts a high (WVGA) resolution of 800x480 pixels.
As the most popular display format is the one featuring 7 inches, being used for digital multimedia broadcasting handsets, PMPs and car navigation systems, Samsung thought of innovating all the capabilities offered. Consequently, it has envisioned an embedded digital LCD chip, which simplifies the task of circuit design in the finished product.
Moreover, the 7 inch display uses Samsung's amorphous silicon gate technology, a patented invention of Samsung's scientists. The innovation is meant especially for the engineers who can design mobile devices with simplified functions and smaller sizes.
