## Abstract

An electronic device that may be a thermostat includes a TN display configured to display at least one icon being interactive, and display information requested via the at least one icon. A control module of the electronic device is coupled to the TN display and is configured to receive a control command from the at least one icon and output the information to the TN display. A computer readable memory of the electronic device is coupled to the control module for storing at least a portion of the information.

## Claims

### Claim 1

A heating, ventilation, and air conditioning thermostat comprising:
a twisted nematic display configured to selectively display an idle screen format and a home screen format, wherein the idle and home screen formats include a common pre-defined first segment configured to selectively display an interactive first icon and an interactive second icon to respectively effect immediately displaying a first set of data relating to the heating, ventilation, and air conditioning thermostat when the interactive first icon is singularly selected upon the idle screen format and immediately displaying a second set of data relating to the heating, ventilation, and air conditioning thermostat on the home screen format when the interactive second icon is singularly selected;
a control module coupled to the twisted nematic display and configured to switch between the idle and home screen formats upon command from the twisted nematic display; and
a non-transitory computer readable storage medium in communication with the control module, and configured to store the idle and home screen formats,
wherein the interactive first icon is displayed in the pre-defined first segment of the twisted nematic display and the first set of data is displayed in a pre-defined second segment of the twisted nematic display when in the idle screen format, and the interactive second icon is displayed in the pre-defined first segment of the twisted nematic display and the second set of data is displayed in the pre-defined second segment when the first set of data is not displayed in the home screen format, and wherein the interactive first icon and the interactive second icon are different in visual appearance;
wherein the twisted nematic display includes a common pre-defined third segment configured to selectively display an interactive advance icon and an interactive third icon, the interactive advance icon being displayed when in the idle screen format and configured to advance the twisted nematic display to the home screen format when selected and thereby change the interactive first icon to the interactive second icon in the pre-defined first segment and change the interactive advance icon to the interactive third icon in the pre-defined third segment;
wherein the interactive third icon is an interactive return icon displayed when in the home screen format and configured to return the twisted nematic display to the idle screen format when selected and change the interactive second icon to the interactive first icon in the pre-defined first segment when the interactive return icon is selected.

### Claim 2 (depends on 1)

The heating, ventilation, and air conditioning thermostat set forth in claim 1, wherein the first set of data includes at least one of outside temperature, outside weather conditions, inside humidity, outside humidity, time of day, replace filter reminder message, system malfunction information, energy usage information, equipment status, and lock status of thermostat.

### Claim 3 (depends on 1)

The heating, ventilation, and air conditioning thermostat set forth in claim 1, wherein the non-transitory computer readable storage medium is configured to store at least a portion of the first and second sets of data.

### Claim 4 (depends on 1)

The heating, ventilation, and air conditioning thermostat set forth in claim 1, wherein the second set of data includes at least one of a tutorial, dealer contact information and IEEE 802.11x registration information.

### Claim 5 (depends on 1)

The heating, ventilation, and air conditioning thermostat set forth in claim 1, wherein the twisted nematic display is configured to display in a plurality of colors as directed by the control module.

### Claim 6 (depends on 1)

The heating, ventilation, and air conditioning thermostat set forth in claim 1, wherein the interactive return icon displayed in the pre-defined third segment of the twisted nematic display is visually different than the interactive advance icon.
