ABSTRACT:
A liquid crystal display (LCD) for a sonar depth-finding device includes a matrix of pixels, each pixel having a first dimension and a second dimension greater than the first dimension such that a ratio of the second dimension to the first dimension is approximately an integer value greater than one. Pixels in the matrix are configured to be operatively associated by the sonar depth-finding device to define a substantially square combined pixel.
