Sharper images brighten prospect of smart projectors

Demand rising from younger consumers, lower-tier cities and overseas markets

With the new UEFA Champions League on, the home of Li Jielin, a 29-year-old software engineer, has become a popular gathering place for his friends.

While beers and Li's good cooking skills are already a draw, the projector he bought recently is even more appealing to his friends.

With the new device, livestreamed matches are projected onto a wall, making Li and his friends feel as if they were at the game.
