EL8323
Small Size LCD Processor
Preliminary Data Brief Version 0.1
GENERAL DESCRIPTION
The EL8323 is a high-quality image processing IC specifically designed for Portable DVD and Car
TV Panels. The EL8323 combines the functionality of scaling and timing control and applies to
commercial available analog and digital panels of various resolutions. The chip has two CCIR656
input channels, an analog output from DAC to support analog panels and a digital output to support
digital panel. The de-interlacing function, sharpness and gamma curve processing features generate
vivid images. In addition, the EL8323 supports 16:9/4:3 aspect ratio/zoom mode display type to meet
all application requirements.
This high quality and low cost single chip solution includes a CCIR656 decoder, one PLL circuit, one
three channel DAC, one internal On Screen Display (OSD), a sophisticated filter, an advanced
scaling engine, and a versatile timing controller (T-Con) for smart-panel integration. With this level of
integration, the EL8323 device simplifies and reduces the cost of portable LCD displays while
maintaining a high degree of flexibility and quality. The output format of EL8323 supports 2.5” ~ 10”
analog and digital TFT-LCD modules.
