HTC says sales of its Windows Mobile- and Android-based phones rose 19 percent in the first quarter on its brand recognition efforts and strengthening consumer demand.

For the three months ending in March, HTC posted revenue of $1.19 billion compared with $997.38 million during the same period last year.

Though the company did not comment on its results, its financial results appear to have been boosted by rising demand for handsets resulting from the emerging global economic recovery. In addition, HTC’s efforts in increasing awareness of its brand appear to be paying off thanks in part to high-profile handset deals with AT&T, T-Mobile USA, Sprint and Verizon Wireless.

HTC is the manufacturer behind Sprint’s highly anticipated 4G handset, the EVO. The Android-based device features a 4.3-inch display, 8-megapixel camera and HD video.

The company made $158.7 million in its first quarter, up slightly from last year when it made $153.9 million.
