A control device for a building includes a segment display. The segment display includes a first character comprising at least seven segments, a second character comprising at least nine segments proximate to the first character, and a connecting character comprising at least two segments located between the first and second character. The control device further includes a processing circuit that, in a first operation, illuminates at least one segment of each of the first character, the second character, and the connecting character to form a first letter and, in a second operation, illuminates at least one segment of each of the first character, the second character, and the connecting character to form a second letter.

Briefly, a method for verifying the visual perceptibility of a display is provided. An intended message is written to a bistable display. Pixels that comprise portions of the message are measured and evaluated to determine if the message actually displayed on the bistable display was perceptible by a human or a machine. In some cases, information regarding the message actually perceivable from the display may be stored for later use. Responsive to determining that a message is perceivable or not perceivable, alarms may be set, one or more third parties notified, or additional display features may be set.

A drive circuit for a liquid crystal panel includes a voltage output device, a resistive voltage dividing circuit, and a low-pass filter.
