Abstract
Abstract A vehicle brake light and display system employs a display screen having an array of light emitting diodes arranged to transmit a selected pattern or message in red light. A fixed or programmable memory has sets of data stored therein that can be selectively extracted to energize certain of the light emitting elements and display a single line of a selected message. Upon actuation of the brake of the vehicle in which the display screen is mounted, display of the message is disabled, and all of the light emitting elements are energized to provide a solid display of red over the entire screen. As a further safety feature, the display is maintained in a disable condition until initial application of the brake, and thereafter subsequent applications of the brake will cause display of the brake light over the entire display panel.

Claim 5
Dependent Claim
24 words
The apparatus of claim 1 wherein said control unit means comprises means for disabling said display prior to receipt of a first brake signal.
Claim 6
Dependent Claim
15 words
The apparatus of claim 1 wherein light transmitted from each of said elements is red.
Claim 7
Dependent Claim
61 words
The apparatus of claim 1 including a message selector having a keyboard, said selector including means responsive to operation of said keyboard for transmitting a message identifying signal to said control unit, said control unit including means responsive to said message identifying signal for transmitting to said display screen a set of data signals corresponding responding to said message identifying signal.
Claim 8
Independent Claim
144 words
A method of providing a rearwardly directed message from a vehicle comprising the steps of: mounting upon a rear portion of the vehicle a display screen having an array of light emitting elements, said array including different groups of elements that form different messages, energizing one of said groups of elements to display a message, and energizing a major part of said array when brakes of the vehicle are applied, said step of energizing one of said groups to display a message comprising the step of storing sets of data in a memory, each said set representing a message to be displayed, selectively extracting at least one of said sets of data from said memory, and employing the selectively extracted set to energize elements of said array of light emitting elements in a pattern that forms a message represented by the selectively extracted set.
Claim 9
Independent Claim
144 words
A method of providing a rearwardly directed message from a vehicle comprising the steps of: mounting upon a rear portion of the vehicle a display screen having an array of light emitting elements, said array including different groups of elements that form different messages, energizing one of said groups of elements to display a message, and energizing a major part of said array when brakes of the vehicle are applied, said step of energizing one of said groups to display a message comprising the step of storing sets of data in a memory, each said set representing a message to be displayed, selectively extracting at least one of said sets of data from said memory, and employing the selectively extracted set to energize elements of said array of light emitting elements in a pattern that forms a message represented by the selectively extracted set.
Claim 10
Independent Claim
108 words
A method of providing a rearwardly directed message from a vehicle comprising the steps of: mounting upon a rear portion of the vehicle a display screen having an array of light emitting elements, providing a plurality of sets of data, each set representing a message to be displayed, employing a selected one of said sets to energize a group of said elements to display a message represented by the selected set, and energizing a major part of said array when brakes of the vehicle are applied, said step of energizing a major part of said array comprising concomitantly interrupting display of said message represented by the selected set.
