DescriptionThe Realtek RTD2010 is a highly-integrated single chip IC controller solution for producing real time, top quality digital video and computer graphic images on LCD monitor/flat panel displays, such as XGA LCD monitors. LCD monitors and flat panel displays provide a sharp, flicker free display while saving space and energy for desktop PC applications. The RTD2010 provides an ideal interface between industry standard digital graphics controllers and a wide variety of LCD panel devices. Flat panel devices using the RTD2010 can support all incoming VESA modes and interface to any TFT LCD device, up to XGA (1024x768) resolution.
For increased flexibility, the RTD2010 supports both analog and digital interface inputs. The embedded 8-bit triple-channel 110MHz high-quality Analog to Digital Converter (ADC) and PLL support up to a 1024x768 75Hz RGB analog input signal.
The digital interface can support Transmission Minimized Differential Signaling (TMDS) receiver or Video-Decoder or DVO digital output signals up to 160MHz.
The RTD2010 features an embedded On-Screen Display (OSD) engine. This OSD enables either character based or bit map based menu display. Through this menu, display parameters, such as brightness and contrast, can be controlled, and information on resolution and frequency, can be displayed. The embedded display pattern generator is a function for panel testing.
Processing 24-bit RGB or 16-bit YUV input data streams, and conversion of input VGA signals to high resolution output, the RTD2010 implements a sophisticated scaling algorithm. This feature allows the RTD2010 to perform horizontal and vertical interpolation or replication and up & down image scaling, based on programmable parameters, to create images of the highest quality. The built-in advanced filtering engine enables independent vertical and horizontal zoom/shrink, and, through enhancement of individual pixels, enhances image sharpness, and provides superb visual quality. This allows appropriate sized display of crisp,sharp text and smooth, clear graphics, taking full advantage of LCD flat panel technology.
Also featured are enhanced color processing functions, including gamma correction and dithering logic. Brightness, contrast and gamma correction can be programmed through the internal gamma correction lookup tables. Full control of output panel data is obtained by color mapping input RGB data. The 8-bit/color pixel path offers up to 16.7 million color support for 24-bit TFT LCD panels. 18-bit LCD panels are also supported through spatial and temporal dither algorithms.
Increased integration in the RTD2010 includes components such as an 8032 compatible micro controller, and DDC RAM to provide monitor information the PC through the DDC1/DDC2B protocol. Internal System Programming (ISP) is accomplished through the DDC serial bus, supporting enhanced DDC-communication from PC to monitor, such as DDC/CI is also supported.
Finally, the Timing-Controller (TCON) generates the control signals for LCD-panel rather than LCD-monitor, and the embedded spread-spectrum technology reduces EMI effects.
All these features make the RTD2010 is the optimum solution for superior-quality image display.
