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:
- a plurality of function buttons;
an electroluminescent display showing a symbol indicating an operating status of the land mobile radio and showing labels for the plurality of function buttons,wherein the function buttons are positioned separate from and under the electroluminescent display;
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,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 one or more images comprising the symbol to indicate the changed state of the land mobile radio,wherein the symbol is depicted and not depicted responsive to changes in the state of the land mobile radio and on the electroluminescent display of the land mobile radio proximate to the labels for the plurality of function buttons, andwherein at least one of the labels is displayed continuously during the changes in the 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 video driver connected to the controller and buffering the one or more images into a video stream for rendering on the electroluminescent display, a control head having the electroluminescent display rendering images formed of the display data, a plurality of push buttons comprising function buttons on the control head separate from and under the electroluminescent display; wherein a first portion of the images comprise labels for the plurality of function buttons separate from and under the electroluminescent display, wherein a second portion of 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 second portion of the images comprising the symbol indicating operating status of the land mobile radio proximate to the first portion of the images comprising the labels for the plurality of function buttons separate from and under the electroluminescent display wherein the symbol is depicted and not depicted responsive to changes in the state of the land mobile radio and on the electroluminescent display of the land mobile radio proximate to the labels for the plurality of function buttons, and wherein at least one of the labels is displayed continuously during the changes in the state of the land mobile radio. - View Dependent Claims (12, 13, 14, 15, 16, 17, 19)
