The right silicon for your Display solutions
Hi3120 High Definition Display solutions

The Hi3120 is a highly-integrated video scan converter for flat panels and CRT TV with de-interlacing, image scaling, video enhancement, CPU and graphic interface. Therefore, the Hi3120 has various applications as follows:
With both digital and analog output interfaces, the Hi3120 can be applied in flat panels and CRT TV
Dynamic 3-D technology filters noise and provides high-quality image
By digital image processing technology,  Hi3120 outputs high-quality image to the terminal after converting the output formats according to different display timings
Integrated MCU, BITMAP-OSD and DAC into a single chip, Hi3120 provides cost-effective solutions with fewer peripherals
Adaptively detecting whether pixels are moving or static according to continuous and multi-field information of input video images
Supporting 16-color and 256-color palettes (Selecting only one type at the same time)
DLTI and DCTI process luminance or chroma signals and make the transition of the related edge steeper
