Abstract

A control and display system for an electronic security system which comprises a thin flat multilayer panel which provides a touchpad for entry of data and display areas for the selective display of messages and legends. The system is contained within a small wall mounted housing which includes a microprocessor controller cooperative with the panel. The system operates as a data terminal in communication with a master control unit and is operative in response to touchpad actuation for providing data to the remote unit, and it is operative in response to data received from the remote unit for actuating displays and associated annuciators. The system is programmable via the front panel, and input and display modes can be tailored to suit particular operational requirements.

Claims

1. An interactive display system comprising:

a first layer containing touchpad areas providing electrical signals representative of respectively actuated areas;

a second layer containing messages in registration with respective ones of the touchpad areas of the first layer;

a third layer containing liquid crystal areas in registration with respective ones of the message areas of the second layer;

a fourth layer containing an electroluminescent illuminator; and

means for retaining the layers in laminated disposition.

2. The system of claim 1 wherein the touchpad areas are transparent.

3. The system of claim 1 wherein the touchpad areas are arranged in a matrix of areas.

4. The system of claim 1 wherein the second layer includes a matrix area containing alphanumeric information, a first contiguous area containing message data, and at least one second contiguous area containing additional message data.

5. The system of claim 4 wherein the third layer is in registration with only a portion of the message areas of the second layer.

6. A control and display system comprising:

a thin flat multilayer panel providing a touchpad for entry of data and display areas for the selective display of message data;

a housing containing the multilayer panel and having a window area for access to the touchpad and display areas;

control circuitry disposed in the housing and including a microprocessor controller cooperative with the panel for selective energization of the display areas and for decoding of touchpad actuation wherein at least some of the selectively energized display areas are in registration with said touchpad; and

means for coupling the microprocessor to a remote master control for data transmission between the microprocessor and master control.

7. The system of claim 6 wherein the housing includes a window area in which the multilayer panel is disposed;

an area contiguous to the window area and containing visual system data and a door for selectively uncovering the contiguous area.

8. The system of claim 6 wherein the housing includes a rear section attachable to a mounting surface, and a front section attachable to the rear section and having a circuit board mounted therein to which the panel is attached.

9. A display and control for an electronic security system comprising:

a housing adapted for attachment to a mounting surface and having a window area visible to a user;

control circuitry in the housing including a microprocessor and memory means;

a multilayer flat panel disposed in the window area of the housing and having transparent touch sensitive keypads coupled to the control circuitry and operative upon manual actuation to enter data into the memory of the control circuitry;

display areas at least some of which are in registration with the touchpad areas and coupled to the control circuitry for selective activation to provide selective visual displays in the window area.

10. The invention of claim 9 wherein the window area is blank when no messages are to be displayed.

11. The invention of claim 9 wherein portions of the window area provide touchpad input functions and display functions.

12. The invention of claim 9 wherein the control circuitry is coupled to a remote unit for communication of data therebetween.

13. The invention of claim 9 wherein the control circuitry is operative to decode inputs from the keypads and actuate corresponding messages on the display and to provide coded data for transmission to a remote unit in response to selected keypad actuation, and operative in response to data from a remote site to display messages and provide data in response thereto.

14. The invention of claim 9 further including visual indicators in the housing and visible via the window area and operative in response to actuation by the control circuitry to denote trouble and status conditions.

15. The invention of claim 14 further including an audible indicator in the housing and operative upon actuation by the control circuitry to audibly denote trouble and status conditions.

16. The invention of claim 15 wherein the audible indicator is operative to sound during each keypad actuation to provide audible feedback to a user.

17. The invention of claim 9 wherein the control circuitry is programmable via the keypad to establish intended operating conditions.

18. The invention of claim 9 wherein the control circuitry is programmable via the keypads to energize the display areas in selected intended manner.

19. The invention of claim 9 wherein the window area includes a matrix area having keypads for data entry and superimposed message areas for selective display.
