Pixelworks, of the US, has caught our eye.

The processor firm -- famous for improving cinema flicks and home projectors -- is now driving a big push into 5G smartphones this year.

Pixelworks designs mobile visual processors for image and video processing, such as the i6 chip with AI and adaptive picture quality. The processors make your Hollywood movie or COD game by smartphone look smoother, brighter, crisper. Less video stutter, higher-def motion, and better picture quality.

In recent Q4 financial results, the CEO outlined how its global smartphone customer base roughly doubled (from a low base) in 2020. A strong focus on China and OLED displays has enabled it to work with OPPO, OnePlus, TCL and others. The Chinese brands like Pixelworks.
