Overview
The LC74986NWF and LC74986NWV are video signal processing ICs that perform resolution conversion, interlaced
to progressive scan (IP) conversion, and image quality improvement without requiring the use of external field (frame)
memory. These ICs can display a wide variety of video signals and formats on a flat panel display. These ICs also
provide image quality improvement and adjustment functions to create the optimal image quality for the flat panel
display used. They also include an OSD function that displays characters with the sizes optimal for the size of panel
used. A flat panel TV monitor with the necessary video signal processing circuits can be formed easily by combining
one of these ICs with a video decoder, A/D converters, a microcontroller, and an LCD panel.
Features
Multi-source support
— NTSC, PAL, and DTV (480i and 480p) inputs
— Progressive scan inputs up to XGA (The LC74986NWV supports up to SVGA.)
— Supports both RGB and YCbCr (4:4:4 24 bits, 4:2:2 16 bits or 8 bits) inputs (built-in YCbCr to RGB converter).
Resolution conversion
— Independent horizontal and vertical expansion and reduction in the horizontal direction
— Interlaced to progressive scan conversion
Image quality correction
— Sharpness, color, tint, white/black stretch, brightness, contrast, white balance, black balance
— Built-in lookup table based gamma correction circuit (Common characteristics for each 8-bit RGB value can be
programmed.)
Panel interface
— Single RGB 24-bit or 18-bit, or dual RGB 48-bit or 36-bit signal output (built-in dither processing)
— Horizontal sync signal, vertical sync signal, data enable signal, and pixel clock outputs
Other features
— No external frame memory required (The input and output have the same frame period.)
— Built-in OSD function (510 characters, 8 colors, built-in 8-character font RAM)
—I2C bus interface (The OSD function can also be controlled over a 3-wire bus.)
— Low-power design
