CONTROL HEAD WITH ELECTROLUMINESCENT PANEL IN LAND MOBILE RADIO
First Claim
1. A control head of a land mobile radio, the control head of the land mobile radio comprising:
- an electroluminescent display showing labels for a plurality of function buttons under the electroluminescent display and a symbol indicating operating status of the land mobile radio;
a control head controller configured to receive data to construct the data into one or more images; and
a video driver connected to the control head controller and buffering the one or more images into a video stream for rendering on the electroluminescent display,wherein the one or more images comprises the labels and the symbol,wherein the one or more images comprising the labels is displayed continuously,wherein the one or more images comprising the symbol is selectably displayed in response to a change in a state of the land mobile radio, andwherein the control head controller is further configured to detect the change in the state of the land mobile radio and to control activation of the one or more images comprising the symbol to indicate the changed state of the land mobile radio.

Abstract
An exemplary land mobile radio control head and method are provided. In one embodiment, the control head has the capability to utilize halo light of the control head to implement a multi-function indicator that communicates a state of the land mobile radio. In another embodiment, the control head has the capability to provide buffer images constructed from data received from the land mobile radio into a video stream for rendering on an electroluminescent display. In another embodiment, the control head provides the capability for a user to modify a configuration stored on the land mobile radio that defines one of several display modes to be utilized in generating data for use in forming images to be rendered on an electroluminescent display.

11. A system for configuring a control head of a land mobile radio having an electroluminescent display, the system comprising:
-
a computer memory storing a configuration; a controller configured to generate display data according to one of various display modes as defined by the configuration; a control head having the electroluminescent display rendering images formed of the display data, wherein the images comprise labels for a plurality of function buttons under the electroluminescent display, wherein the images comprise a symbol indicating operating status of the land mobile radio; a computer processor executing a process whereby a user of the computer processor specifies the display mode to be defined by the configuration; and a control head controller to determine the state of the land mobile radio, to detect a change in the state of the land mobile radio, and to control activation of the images displayed on the electroluminescent display to indicate the changed state of the land mobile radio and displaying the symbol indicating operating status of the land mobile radio proximate to the labels for the plurality of function buttons. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A control head of a land mobile radio, the control head of the land mobile radio comprising:
-
a plurality of indicator LEDs comprising at least a first color LED having a first hue, a second color LED having a second hue, and a third color LED having a third hue and controllable independently of the first color LED and independently of the second color LED, a signal line to the third color LED and connected to a control head controller; and the control head controller configured to determine a state of the land mobile radio as being one of a transmit state, a receive state, or an idle state, wherein the control head controller is further configured to detect the change in the state of the land mobile radio and to control activation of the plurality of indicator LEDs to indicate the changed state of the land mobile radio by illuminating the third color LED the third hue to indicate the changed state is the idle state, illuminating the first color LED a first hue to indicate the changed state is the transmit state, and illuminating the second color LED a second hue to indicate the changed state is the receive state, and wherein the first hue comprises a brightness separately controllable by the control head controller and different than a brightness of the second hue when the second color LED is illuminated and different than a brightness of the third hue when the third color LED is illuminated. - View Dependent Claims (19, 20)
