Levetop Semiconductor

With the development of TFT/LCD technology, now more and more product is trend to apply a colorful TFT panel instead of old fashioned monochrome panel. In order to make the image smoothly displayed on the TFT panel , or to add some vivid effect such as rotation, sub-menu pop-up, even GIF animation, MCU need to do lots work and software developers takes weeks even months to realize the effect and debug. At this time, the TFT controller can play a very important role here, to release the MCU burden, and reduce software developers boring work.

Levetop is an uprising fabless IC design company derived from the market trend, with its main product : TFT LCD graphics acceleration display controller and serial TFT panel solution. LeveTop is a professional IC research and development company with independent intellectual property rights, with a strong R&D team, marketing team and FAE team. Now LeveTop Semiconductor is a technology leader in TFT LCD Controller field in China.
