Abstract
The present disclosure provides an ultrasonic probe. The ultrasonic probe includes a piezoelectric layer, including a number of piezoelectric posts arranged in a number of rows along a first direction and arranged in a number of columns along a second direction, and an angle between the first direction and the second direction being an acute angle, a distance between the two adjacent piezoelectric posts along the first direction being greater than a distance between the two adjacent rows of the piezoelectric posts. The ultrasonic probe improves the density of the piezoelectric post by misaligning the two adjacent rows of piezoelectric posts and compressing the row spacing, which makes better use of the space between the two adjacent rows of piezoelectric posts. That is, the space utilization of the ultrasonic probe is improved and pixel density is high.
