The LC74982W is an LCD display scan converter IC that converts NTSC and PAL TV signals to XGA resolution. The video signal-processing circuits required to implement an LCD TV set can be easily formed by combining this IC with a digital decoder, a microcontroller, and an LCD panel. Since this IC does not require an external frame memory for resolution conversion, it can contribute to minimizing total costs. As additional functionality, it also provides inputs for personal computer video (up to XGA) and digital TV (480p/480i). Since LC74982W operation is based on expansion (resolution increasing) processing, depending on the input resolution, it can also support use of, for example, 800 x 600 and 800 x 480 dot resolution LCD panels. Thus the LC74982W can be used in a wide range of applications.
